Bypassing primary care facilities health-seeking behavior of middle age and olderadults in ChinaChangle Li12 Zhuo Chen23 and M Mahmud Khan2
Abstract
Background With economic development aging of the population improved insurance coverage and theabsence of a formal referral system bypassing primary healthcare facilities appear to have become more commonChinese patients tend to visit the secondary or tertiary healthcare facilities directly leading to overcrowding at thehigher-level facilities This study attempts to analyze the factors associated with bypassing primary care facilitiesamong patients of age 45 years or older in China
Methods Random effects logistic models were used to examine bypassing of primary health facilities among rural-urban patients Data from 2011 to 2015 waves of the China Health and Retirement Longitudinal Study were used
Results Two in five older patients in China bypass primary health centers (PHC) to access care from higher-tierfacilities Urban patients were nearly twice as likely as rural patients to bypass PHC Regardless of rural-urban residenceour analysis found that a longer travel time to primary facilities compared to higher-tier facilities increases thelikelihood of bypassing Patients with higher educational attainment were more likely to bypass PHCs In rural areaspatients who reported their health as poor or those who experienced a recent hospitalization had a higher probabilityof bypassing PHC In urban areas older adults (age 65 years or older) were more likely to bypass PHC than the youngergroup Patients with chronic conditions like diabetes also had a higher probability of bypassing
Conclusions The findings indicate the importance of strengthening the PHCs in China to improve the efficiency andeffectiveness of the health system Significantly lower out-of-pocket costs at the PHC compared to costs at the highertiers had little or no impact on increasing the likelihood of utilizing the PHCs Improving service quality providingcomprehensive person-centered care focusing on family health care needs and providing critical preventive serviceswill help increase utilization of PHCs as well as the effectiveness and efficiency of the health system

BackgroundHealth system of China established a three-tier health-care delivery structure in both rural and urban areassince 1950s The essential features of this system haveremained quite stable even today with a network con-necting healthcare providers at county township andvillage levels in rural areas and at municipal districtand community levels in urban areas [1] Despite struc-tural stability the 1978 economic liberalization signifi-cantly affected the functioning of the health facilities atall levels The multi-level referral system is now virtuallyabsent [2 3] With the rapid demographic transition andaging of the population the prevalence of chronic dis-eases and disabilities has increased [4] Many local levelprimary centers (PHCs) are not ready to offer chronicdisease management [5] Another significant change wasthe adoption of a universal health insurance scheme thathas provided coverage to 95 of the population since2011 [6] With rapid economic development aging ofthe population improved insurance coverage and lackof formal referral structure bypassing PHCs to seek carefrom secondary and tertiary healthcare facilities (STFs)have increased leading to overcrowding at the higher-tier facilities [7]Since the 2009 health reforms in China significant in-
vestments were made to strengthen primary care infra-structure [7 8] Many PHCs were constructed andorupgraded [9] In 2019 there were approximately 9300community health centers and 26000 community healthclinics in urban areas and 36000 township health cen-ters and 622000 village clinics in rural areas Today al-most every community has at least one PHC [10] Inaddition to encourage utilization of PHCs basic medicalinsurance schemes reimburse a higher proportion ofcosts to patients for seeking care from the PHCs ratherthan from STFs [11] The zero-profit drug policy as partof the national essential drug system (NSDS) was intro-duced in PHCs in 2009 Under the NSDS the PHCsmust sell drugs at cost without any mark-up [12 13]Despite these financial incentives in favor of PHCs thereappears to be no decline in the propensity to bypassPHCs [8]Bypassing the PHCs can adversely affect health system
performance and contributes to higher medical expendi-tures [14] People who bypass PHCs report spending ap-proximately two times more on healthcare than thosewho do not bypass PHCs [15 16] Although bypassingof PHCs has become widespread there is limited evi-dence on reasons and consequences of bypassing inChina Most studies on bypassing conducted in selectedcountries in Asia Africa and the Americas definedbypassing as incidents where people travel to another fa-cility to obtain care rather than using the nearby localfacility [17ndash23] Few other studies have defined
bypassing as skipping the PHCs to obtain care fromSTFs [24ndash26] without explicitly considering the distanceto facilities from patientsrsquo residencesIn the literature several factors are found to be im-
portant in explaining the bypassing phenomenon Im-portant demographic and socioeconomic factors includeage gender marital status educational attainment in-come health insurance status and health conditionsSanders et al [27] Shah [28] and Yao and Agadjanian[23] found that older patients are more likely to bypasslocal providers However Liu et al [29] Escarce andKapur [30] and Tai et al [31] reported the opposite forpatients in the USA Liu et al [29] found that patientswho have some college education are less likely to by-pass but Akin and Hutchinson [17] and Damrongplasitand Wangdi [25] observed the opposite Similarly Liuet al [29] and Perera and Weerasinghe [32] found apositive association between being married and bypass-ing but Damrongplasit and Wangdi concluded to thecontrary [25] In the USA like the Chinese health sys-tem most insurance plans allow patients to seek carefrom upper-level providers or facilities without formalreferralsEffects of gender socioeconomic status and health
conditions on bypassing tendency were similar acrossseveral studies Rao and Sheffel [26] and Akin andHutchinson [17] found that females are more likely thanmales to bypass local providers Rao and Sheffel [26] andYao and Agadjanian [23] reported a higher likelihood ofbypassing with increasing income or wealth Radcliffet al [33] found that uninsured patients have a lowertendency to bypass and Akin and Hutchinson [17] andTai et al [31] found that bypassing local facilities in-creases with increasing severity of medical conditionsSanders et al [27] on the other hand reported thatbypassing is more common among patients with betteroverall self-rated healthProvider characteristics associated with bypassing
include size of the practice availability of technologyservice quality and mix cost and ownership Escarceand Kapur [30] found that patients are less likely tobypass large local providers with extensive techno-logical capabilities Perceived poor quality of localhealthcare providers increases bypassing (Paul andRumsey [21] Kruk et al [18] Liu Bellamy et al [20]and Sanders et al [22]) Leonard et al [34] reportedthat patients in Tanzania bypass health providers thatoveruse injections or overprescribe drugs Patientswith relatively low income may bypass local providersto seek care from less expensive providers [16] Rohand Moon [35] and Escarce and Kapur [30] observedthat patients in rural USA are more likely to bypasslocal public-sector providers to access care from pri-vate providers
Li et al BMC Health Services Research (2021) 21895 Page 2 of 12
Patients are less likely to bypass local health care pro-viders when the distance to alternative providers is rela-tively high (Tai et al [31] Escarce and Kapur [30] andLeonard et al [34]) Varkevisser and van der Geest [36]reported that distance is an important factor in thechoice of hospitals ie patients are less likely to bypassthe nearest hospital when travel time to the next-nearesthospital increasesUnderstanding the reasons for bypassing PHCs will
help design government policies on how to make thePHCs more effective at the local level Despite the im-portance of the topic only a few studies have analyzedthis phenomenon using large longitudinal datasets Thisstudy is an attempt to understand the factors affectingthe propensity to bypass PHCs in China despite thecost-advantages created by policy makers to encouragethe utilization of PHCs
MethodsTheoretical and empirical modelsPatients have options in terms of health facilities theycan use For this analysis the current study defines theoptions as either seeking care from the ldquoprimary carecenterrdquo in the locality (PHC) or choosing an alternativeldquosecondary or tertiary facilityrdquo (STF) Patients in theorywill choose a facility-type that provides them a higherlevel of utility (u) ie if ui(PHC) lt ui(STF) patient i islikely to seek care from secondary or tertiary health fa-cilities The literature suggests that the utility u() associ-ated with the use of a health facility type may depend onseveral factors including patient characteristics illnesstype facility characteristics costs associated with seekingcare health system design Since the choice has been de-fined as a dichotomous outcome this study can developthe model by considering the likelihood of not selectingPHC [p(~PHC)] Therefore the generalized model ofbypassing PHCs can be written as

where X is a vector of individual characteristics (agegender income) Z is facility-specific characteristics (egfacility size technology availability perceived quality) Cis the out-of-pocket expenses associated with thefacility-types T is travel distances and R representsother factors (eg physician recommendations on choiceof facilities)Given patient characteristics choosing a health facility
will require comparing the relevant factors between thelocal facility and other potentially accessible facilities InChina utilization of PHCs will be less expensive thanobtaining care from upper-level facilities and insurancecoverage lowers the cost of using PHCs even furtherTherefore insurance status may be used as one of the
proxy variables of financial incentives to access PHCsHigher-tier facilities by definition provide more com-prehensive healthcare services using better equipmentand technology Therefore higher severity and relativelycomplex medical conditions may benefit from accessingcare from higher-tier facilities One important factor thataffects the choice of facilities is their relative distances Ifthe closest STF is located relatively far away from acommunity patients may elect to use PHC keepingother factors constant For empirical estimation the ra-tio of the distances to PHC and STFs may be used torepresent the relative degrees of accessibility of the facil-ities This ratio is expected to be less than 10 but thehigher the ratio the greater should be the likelihood ofbypassingFor the analysis of bypassing behavior the probability
of not using PHC [p(~PHC)] the first step was to carry-out simple descriptive analysis to understand the differ-ences between patients who bypass PHCs (bypassers)and those who do not (non-bypassers) Pearsonrsquos chi-square test was used to analyze the categorical inde-pendent variables For the multivariate analysis it is as-sumed that there is an unobserved latent variable yitaffecting the decision to bypass

Data sourceThe China Health and Retirement Longitudinal Study(CHARLS) conducted by the National School of Devel-opment of Peking University is the data set used for thisanalysis The sample of CHARLS was drawn from 450villages or urban communities of 150 counties or equiva-lent urban districts in 28 provinces A multistage strati-fied sampling with probability proportional to size wasused for the survey More details on the sampling anddata collection process are available in Zhao et al [38]The CHARLS is nationally representative and collectsdata from persons of age 45 years or older and theirspouses The CHARLS respondents are reinterviewedevery 2 years with the first wave in 2011 covering17705 persons and two follow-ups in 2013 and 2015with 18605 persons and 21095 persons respectivelyThe CHARLS questionnaires include questions onhousehold characteristics demographic backgroundhealth status and physical functioning health careutilization insurance status work retirement and pen-sion income expenditure asset ownership housingcharacteristics etc From the datasets only the individ-uals who sought outpatient care during the previous 4weeks before the date of interview were selected Thefinal sample consisted of a total of 10061 individuals inall three waves combined
MeasuresRural and urban definitionsIn the CHARLS each adult was asked ldquoWhat is the typeof your addressrdquo and ldquoIs it a rural village or urban com-munityrdquo All respondents were classified as either ruralor urban residents based on their responses
Dependent variableThe PHCs in China provide generalist clinical care andbasic public health services through community healthcenters and clinics in the urban areas and township hos-pitals and village clinics in the rural areas [13 39] Inthis study bypassing PHCs has been defined as skippingany primary care facilities to obtain care from the
secondary or tertiary level Responses to the followingsurvey questions were used to identify the incidence ofldquobypassingrdquo (1) Which healthcare provider did you visitmost recently during the past 4 weeks 1 General hos-pital 2 Specialized hospital 3 Chinese medicine hos-pital 4 Community healthcare center 5 Townshiphospital 6 Community health clinic 7 Village clinicPrivate clinic and 8 Other and (2) Did the providervisit you at home 1 Yes and 2 No If a respondent an-swered Question (1) by selecting any of General hospitalSpecialized hospital or Chinese medicine hospital andreported ldquoNordquo on Question (2) the patient is consideredto have had a ldquobypassingrdquo of the PHC The respondentswho reported using ldquoOtherrdquo providers in Question (1) orldquoYesrdquo to Question (2) were dropped from this studysample
Independent variablesIndependent variables were chosen based on theoreticalconsiderations and literature review The survey col-lected data on travel time to the facility for each of thepatients Therefore those who obtained care from PHCsreported travel time to the PHCs while those who vis-ited the upper-level facilities (STFs) reported travel timeto those facilities Reported travel times to facility-types(PHCs or STFs) were used to predict the travel times toPHCs and STFs for all patients living in a communitybut did not visit the facility-type The average travel timeto PHCs for patients living in a community for examplewas used to approximate the travel time of those livingin the same community but did not use the PHCs Thesame method was used to predict the travel time fromhome to an STF for patients in each community Rela-tive travel time was defined as the ratio of travel time toa PHC to travel time to an STFChina has two basic medical insurance schemes
Urban Employee Basic Medical Insurance and Urbanand Rural Resident Basic Medical Insurance (the medicalinsurance of integrating Urban Resident Basic MedicalInsurance and New Rural Cooperative Medical Schemeofficially in 2016) Insurance status affects out-of-pocketexpenses of patients differentially for seeking care fromPHCs and STFs Another critical factor affecting bypass-ing is patientsrsquo medical conditions especially the pres-ence of chronic conditions This analysis included anextensive list of chronic conditions including hyperten-sion dyslipidemia diabetes cancer chronic lung dis-eases liver disease heart diseases stroke emotionalnervous or psychiatric problems Definitions of the vari-ables are given in Table 1
Data analysisThis analysis is based on a sample of 10061 respon-dents who sought outpatient care during the 4 weeks

prior to the survey date Since follow-up visits maybias the results this study has estimated the modelsseparately for all visits (first visit and revisits) and thefirst visits The sample size for first visits for an epi-sode of illness was 4720 If the primary care providersin the first visits refer patients to specialists the sub-sequent visits may reflect physician recommendationsrather than patientsrsquo decision-making In other wordsat least some of the revisits may not be consideredbypassing of the PHCsLogistic regression models were employed to analyze
factors affecting propensity to bypass PHCs stratified byrural-urban residence Since access to health facilitiesdiffers significantly between rural and urban areas thestratification is important to avoid potential bias createdby rural-urban differences (see Table A1 of Additionalfile 1) The annex table also identifies a number of rele-vant variables for inclusion in the regression models Inmost panel studies the preferred empirical model wouldbe either the fixed-effects or the random-effects logisticmodel [37] and empirical results should guide the choicebetween the model-typesWhen estimating the patient fixed effects model
whenever patients bypass (or do not bypass) PHC in twowaves or all three waves by definition variations overtime becomes zero and the empirical model will dropthe cases In the full sample of the fixed effects logisticmodels 6620 out of 7672 rural patients and 2185 out of2389 urban patients were dropped because of lack ofinter-temporal variation The random-effects model usesall the available observations and allows estimation ofparameters and standard errors [40] This study usedHausmanrsquos specification test for the random effects lo-gistic regression models to test the orthogonality of therandom effects and the regressors [41] The Hausmantest suggests that the random-effects model is preferredover the fixed-effects model
ResultsAmong those who used outpatient services the percentof patients bypassing PHCs were 340 in Wave 1394 in Wave 2 and 418 in Wave 3 indicating an in-creasing trend of bypassing over the years In rural areasthe percent bypassing PHCs were 270 in Wave 1330 in Wave 2 and 346 in Wave 3 In contrast thepropensity to bypass PHCs remained almost static inurban areas over the years ndash 624 in Wave 1 611 inWave 2 and 601 in Wave 3 Urban patients werenearly twice as likely as rural patients to bypass PHCsThe results remained similar when only the first visitswere considered ie excluding the follow-up outpatientvisits Table A1 of Additional file 1 compares patientcharacteristics by bypassing behavior (patients bypassingPHCs vs those not bypassing) The results indicate thatbypassers differed from non-bypassers in terms of theirresidence educational attainment household incomemedical insurance coverage specific chronic conditionsand the incidence of hospitalizationThe odds ratios of the random effects logistic regres-
sion analysis are reported in Table 2 The results implythat rural patients aged 65 years or older were less likelyto bypass PHCs than patients in the age group 45ndash54years (OR = 064 p lt 0001) In contrast patients aged65 years or older show a higher probability of bypassingin urban areas (OR = 147 p = 0036) The probability ofbypassing PHCs increases with higher educational at-tainment in both rural and urban areas Compared toilliterate patients individuals who attended elementaryschool show increased odds of bypassing by 22 in ruralareas (OR = 122 p lt 0012) and completion of morethan 3 years of college increased the odds by 236 inurban areas (OR = 336 p lt 0001) Urban patients in thelower-middle income category were less likely to bypassPHCs than those with high income (OR = 056 p =0010) A similar trend was observed for patients in the

DiscussionThe nationally representative survey indicates that theproportion of outpatients bypassing PHCs increased overthe years in China Urban patients were nearly twice aslikely to bypass PHCs than rural patients This is not un-expected due to the easy access and availability of manySTFs in urban areas Travel distance and travel-relatedcosts are likely to be lower for the urban population [3642] Rural patients often must rely on PHCs in the areadue to the difficulty of accessing alternative health careproviders Especially for rural residents obtaining carefrom upper-level facilities may become quite expensivedue to higher out-of-pocket expenses and longer traveltimes [43]About two in five older adults in China bypassed
PHCs to obtain care from upper-level providers (STFs)
This is despite significantly lower out-of-pocket costs forservices and drugs at PHCs than at the STFs Thereforefinancial incentives have not been adequate to discour-age bypassing of PHCs in China The results imply thatpropensity to bypass PHCs is unlikely to decline signifi-cantly if the financial incentives in favor of PHCs aremade even stronger Given that the bypassing tendencyis related to age ruralurban location present of chronicconditions etc it points to supply-side concerns prob-ably related to availability and quality of service-mix of-fered at the PHCsThe random-effects logistic regression model identi-
fied several factors affecting bypassing of PHCs for ruraland urban residents separately The estimates suggestthat factors affecting the first visits are very similar tofactors affecting all outpatient visits (both new andfollow-up visits) implying that physician recommenda-tions were not important in influencing the choice offacility-types Regardless of rural-urban residence a rela-tive increase in travel time (ratio of travel times to PHCand STF) increased the probability of bypassing PHCsThe result is consistent with the findings in the litera-ture ie increased travel time lowers the utilization ofhealth care facilities [33 44ndash50] Without a formal refer-ral system in urban areas where health resources aremuch richer and STFs are more concentrated than thosein rural areas in China urban patients are more likely tobypass PHCs because of easy accessibility and availabilityof medical care services they needPatients with higher educational attainment show a
higher probability of bypassing PHCs Educational at-tainment is an indicator of socioeconomic status (SES)as well as knowledge about the relative quality of ser-vices facilities offer Middle-aged and older adults withhigher level of income are also more likely to bypassPHCs This probably indicates perception of lower qual-ity of services at the PHCs compared to the STFs Withan increase in income and educational attainment pa-tients become more sensitive to service quality and lesssensitive to cost savings that can be achieved by utilizingPHCsIn rural areas self-reported poor health status in-
creased the likelihood of bypassing PHCs Again thispossibly reflects a lack of confidence in the quality of

services andor non-availability of individualized servicesat the PHC [51 52] Offering individualized services is aperson-centered care approach [53] Patients who expe-rienced hospitalization in the past 12 months are morelikely to bypass PHCs as the hospitalization in the recentpast may be associated with actual or perceived higherseverity of illness or need for individualized services en-couraging utilization of STFs [29] A number of chronicconditions also affect the choice of facility-type Patientswith arthritis or rheumatism were less likely to bypassPHCs probably because these conditions make travelmore difficult [54] especially for rural patients who musttravel significantly longer distances to reach STFsOlder adults show high degree of bypassing PHCs in
urban areas but for rural areas the opposite was true(middle-aged individuals more likely to bypass than theolder adults) This tendency may be associated with lackof relevant services at the PHC level Older adults re-quire more personalized care and continuity of care isimportant for their health status In contrast for ruralareas social value of protecting the health of middle-aged individuals may be higher and travel to a STF ismore costly and difficult for the elderly Among urbanpatients older adults were more likely to bypass PHCsthan those aged 45ndash54 years Geriatric services have notbeen properly incorporated at the primary level in urbanChina [55] which may explain urban older adultsrsquo hesi-tancy to seek care from the PHCs Urban patients withdiabetes are also more likely to use upper-level facilitiesagain reflecting the lack of chronic disease managementat the primary level [56]In urban areas where the upper-level facilities are eas-
ily accessible the tendency to bypass is significantlyhigher With improvements in health status and theaging of the population patients need individualized aswell as continuity of care services Unless those servicesare offered from the PHCs bypassing problem is ex-pected to increase further [57 58]There are several limitations of this study The
CHARLS survey provides information only on the mostrecent outpatient service utilized in the previous 4weeks Measuring the incidence of bypassing using themost recent outpatient visits within the last 4 weeks may
bias the results The survey did not collect informationon facility and provider characteristics and the studycould not analyze the effect of provider characteristicson the choice of health facilities
ConclusionsAbout two in five older adults in China bypassed PHCsto obtain care from upper-level providers (STFs) Urbanpatients were twice as likely as rural patients to bypassPHCs The present study found that relative increase intravel time and more educated had a higher likelihoodof bypassing primary care in rural and urban areasMoreover poor health status and being hospitalized inthe past 12 months had a higher likelihood of bypassingprimary care in rural areas On the other hand arthritisor rheumatism decreased the odds of bypassing Further-more older age and diabetes had a higher likelihood ofbypassing primary care in urban areasContinuity of care and individualized attention require
redesigning the mode of care delivery at the PHC levelwith emphasis on patient-provider trust and adoption ofproactive health promotion and disease prevention Struc-tural changes including the staffing of the PHCs will beneeded to make the PHCs more effective in addressing theneeds of the elderly and middle-aged individuals The find-ings of the study indicate the importance of strengtheningthe service provision in rural PHCs to address commonchronic conditions In fact improving the service deliveryfor addressing the needs of chronic conditions will im-prove utilization of PHCs in both rural and urban areasIn conclusion improving the utilization of PHCs in
China will require improving the quality of services ren-dered from these facilities Perceived quality of medicalcare delivered from the PHCs can be improved if the facil-ities are able to offer comprehensive person-centeredhealth care focusing on the family health care needs andmaking critical screening and preventive services availableAvailability of services alone will not improve overall qual-ity of services ndash it will require a system of continuity ofcare by ensuring good rapport between patients and phy-sicians If patients feel that they have their own primarycare physician in the PHCs the likelihood of seeking carefrom PHCs should be significantly higher

BackgroundHealth system of China established a three-tier health-care delivery structure in both rural and urban areassince 1950s The essential features of this system haveremained quite stable even today with a network con-necting healthcare providers at county township andvillage levels in rural areas and at municipal districtand community levels in urban areas [1] Despite struc-tural stability the 1978 economic liberalization signifi-cantly affected the functioning of the health facilities atall levels The multi-level referral system is now virtuallyabsent [2 3] With the rapid demographic transition andaging of the population the prevalence of chronic dis-eases and disabilities has increased [4] Many local levelprimary centers (PHCs) are not ready to offer chronicdisease management [5] Another significant change wasthe adoption of a universal health insurance scheme thathas provided coverage to 95 of the population since2011 [6] With rapid economic development aging ofthe population improved insurance coverage and lackof formal referral structure bypassing PHCs to seek carefrom secondary and tertiary healthcare facilities (STFs)have increased leading to overcrowding at the higher-tier facilities [7]Since the 2009 health reforms in China significant in-
vestments were made to strengthen primary care infra-structure [7 8] Many PHCs were constructed andorupgraded [9] In 2019 there were approximately 9300community health centers and 26000 community healthclinics in urban areas and 36000 township health cen-ters and 622000 village clinics in rural areas Today al-most every community has at least one PHC [10] Inaddition to encourage utilization of PHCs basic medicalinsurance schemes reimburse a higher proportion ofcosts to patients for seeking care from the PHCs ratherthan from STFs [11] The zero-profit drug policy as partof the national essential drug system (NSDS) was intro-duced in PHCs in 2009 Under the NSDS the PHCsmust sell drugs at cost without any mark-up [12 13]Despite these financial incentives in favor of PHCs thereappears to be no decline in the propensity to bypassPHCs [8]Bypassing the PHCs can adversely affect health system
performance and contributes to higher medical expendi-tures [14] People who bypass PHCs report spending ap-proximately two times more on healthcare than thosewho do not bypass PHCs [15 16] Although bypassingof PHCs has become widespread there is limited evi-dence on reasons and consequences of bypassing inChina Most studies on bypassing conducted in selectedcountries in Asia Africa and the Americas definedbypassing as incidents where people travel to another fa-cility to obtain care rather than using the nearby localfacility [17ndash23] Few other studies have defined
bypassing as skipping the PHCs to obtain care fromSTFs [24ndash26] without explicitly considering the distanceto facilities from patientsrsquo residencesIn the literature several factors are found to be im-
portant in explaining the bypassing phenomenon Im-portant demographic and socioeconomic factors includeage gender marital status educational attainment in-come health insurance status and health conditionsSanders et al [27] Shah [28] and Yao and Agadjanian[23] found that older patients are more likely to bypasslocal providers However Liu et al [29] Escarce andKapur [30] and Tai et al [31] reported the opposite forpatients in the USA Liu et al [29] found that patientswho have some college education are less likely to by-pass but Akin and Hutchinson [17] and Damrongplasitand Wangdi [25] observed the opposite Similarly Liuet al [29] and Perera and Weerasinghe [32] found apositive association between being married and bypass-ing but Damrongplasit and Wangdi concluded to thecontrary [25] In the USA like the Chinese health sys-tem most insurance plans allow patients to seek carefrom upper-level providers or facilities without formalreferralsEffects of gender socioeconomic status and health
conditions on bypassing tendency were similar acrossseveral studies Rao and Sheffel [26] and Akin andHutchinson [17] found that females are more likely thanmales to bypass local providers Rao and Sheffel [26] andYao and Agadjanian [23] reported a higher likelihood ofbypassing with increasing income or wealth Radcliffet al [33] found that uninsured patients have a lowertendency to bypass and Akin and Hutchinson [17] andTai et al [31] found that bypassing local facilities in-creases with increasing severity of medical conditionsSanders et al [27] on the other hand reported thatbypassing is more common among patients with betteroverall self-rated healthProvider characteristics associated with bypassing
include size of the practice availability of technologyservice quality and mix cost and ownership Escarceand Kapur [30] found that patients are less likely tobypass large local providers with extensive techno-logical capabilities Perceived poor quality of localhealthcare providers increases bypassing (Paul andRumsey [21] Kruk et al [18] Liu Bellamy et al [20]and Sanders et al [22]) Leonard et al [34] reportedthat patients in Tanzania bypass health providers thatoveruse injections or overprescribe drugs Patientswith relatively low income may bypass local providersto seek care from less expensive providers [16] Rohand Moon [35] and Escarce and Kapur [30] observedthat patients in rural USA are more likely to bypasslocal public-sector providers to access care from pri-vate providers
Li et al BMC Health Services Research (2021) 21895 Page 2 of 12
Patients are less likely to bypass local health care pro-viders when the distance to alternative providers is rela-tively high (Tai et al [31] Escarce and Kapur [30] andLeonard et al [34]) Varkevisser and van der Geest [36]reported that distance is an important factor in thechoice of hospitals ie patients are less likely to bypassthe nearest hospital when travel time to the next-nearesthospital increasesUnderstanding the reasons for bypassing PHCs will
help design government policies on how to make thePHCs more effective at the local level Despite the im-portance of the topic only a few studies have analyzedthis phenomenon using large longitudinal datasets Thisstudy is an attempt to understand the factors affectingthe propensity to bypass PHCs in China despite thecost-advantages created by policy makers to encouragethe utilization of PHCs
MethodsTheoretical and empirical modelsPatients have options in terms of health facilities theycan use For this analysis the current study defines theoptions as either seeking care from the ldquoprimary carecenterrdquo in the locality (PHC) or choosing an alternativeldquosecondary or tertiary facilityrdquo (STF) Patients in theorywill choose a facility-type that provides them a higherlevel of utility (u) ie if ui(PHC) lt ui(STF) patient i islikely to seek care from secondary or tertiary health fa-cilities The literature suggests that the utility u() associ-ated with the use of a health facility type may depend onseveral factors including patient characteristics illnesstype facility characteristics costs associated with seekingcare health system design Since the choice has been de-fined as a dichotomous outcome this study can developthe model by considering the likelihood of not selectingPHC [p(~PHC)] Therefore the generalized model ofbypassing PHCs can be written as
p PHCeth THORN frac14 f ZCT RjXeth THORN
where X is a vector of individual characteristics (agegender income) Z is facility-specific characteristics (egfacility size technology availability perceived quality) Cis the out-of-pocket expenses associated with thefacility-types T is travel distances and R representsother factors (eg physician recommendations on choiceof facilities)Given patient characteristics choosing a health facility
will require comparing the relevant factors between thelocal facility and other potentially accessible facilities InChina utilization of PHCs will be less expensive thanobtaining care from upper-level facilities and insurancecoverage lowers the cost of using PHCs even furtherTherefore insurance status may be used as one of the
proxy variables of financial incentives to access PHCsHigher-tier facilities by definition provide more com-prehensive healthcare services using better equipmentand technology Therefore higher severity and relativelycomplex medical conditions may benefit from accessingcare from higher-tier facilities One important factor thataffects the choice of facilities is their relative distances Ifthe closest STF is located relatively far away from acommunity patients may elect to use PHC keepingother factors constant For empirical estimation the ra-tio of the distances to PHC and STFs may be used torepresent the relative degrees of accessibility of the facil-ities This ratio is expected to be less than 10 but thehigher the ratio the greater should be the likelihood ofbypassingFor the analysis of bypassing behavior the probability
of not using PHC [p(~PHC)] the first step was to carry-out simple descriptive analysis to understand the differ-ences between patients who bypass PHCs (bypassers)and those who do not (non-bypassers) Pearsonrsquos chi-square test was used to analyze the categorical inde-pendent variables For the multivariate analysis it is as-sumed that there is an unobserved latent variable yitaffecting the decision to bypass

Data sourceThe China Health and Retirement Longitudinal Study(CHARLS) conducted by the National School of Devel-opment of Peking University is the data set used for thisanalysis The sample of CHARLS was drawn from 450villages or urban communities of 150 counties or equiva-lent urban districts in 28 provinces A multistage strati-fied sampling with probability proportional to size wasused for the survey More details on the sampling anddata collection process are available in Zhao et al [38]The CHARLS is nationally representative and collectsdata from persons of age 45 years or older and theirspouses The CHARLS respondents are reinterviewedevery 2 years with the first wave in 2011 covering17705 persons and two follow-ups in 2013 and 2015with 18605 persons and 21095 persons respectivelyThe CHARLS questionnaires include questions onhousehold characteristics demographic backgroundhealth status and physical functioning health careutilization insurance status work retirement and pen-sion income expenditure asset ownership housingcharacteristics etc From the datasets only the individ-uals who sought outpatient care during the previous 4weeks before the date of interview were selected Thefinal sample consisted of a total of 10061 individuals inall three waves combined
MeasuresRural and urban definitionsIn the CHARLS each adult was asked ldquoWhat is the typeof your addressrdquo and ldquoIs it a rural village or urban com-munityrdquo All respondents were classified as either ruralor urban residents based on their responses
Dependent variableThe PHCs in China provide generalist clinical care andbasic public health services through community healthcenters and clinics in the urban areas and township hos-pitals and village clinics in the rural areas [13 39] Inthis study bypassing PHCs has been defined as skippingany primary care facilities to obtain care from the
secondary or tertiary level Responses to the followingsurvey questions were used to identify the incidence ofldquobypassingrdquo (1) Which healthcare provider did you visitmost recently during the past 4 weeks 1 General hos-pital 2 Specialized hospital 3 Chinese medicine hos-pital 4 Community healthcare center 5 Townshiphospital 6 Community health clinic 7 Village clinicPrivate clinic and 8 Other and (2) Did the providervisit you at home 1 Yes and 2 No If a respondent an-swered Question (1) by selecting any of General hospitalSpecialized hospital or Chinese medicine hospital andreported ldquoNordquo on Question (2) the patient is consideredto have had a ldquobypassingrdquo of the PHC The respondentswho reported using ldquoOtherrdquo providers in Question (1) orldquoYesrdquo to Question (2) were dropped from this studysample
Independent variablesIndependent variables were chosen based on theoreticalconsiderations and literature review The survey col-lected data on travel time to the facility for each of thepatients Therefore those who obtained care from PHCsreported travel time to the PHCs while those who vis-ited the upper-level facilities (STFs) reported travel timeto those facilities Reported travel times to facility-types(PHCs or STFs) were used to predict the travel times toPHCs and STFs for all patients living in a communitybut did not visit the facility-type The average travel timeto PHCs for patients living in a community for examplewas used to approximate the travel time of those livingin the same community but did not use the PHCs Thesame method was used to predict the travel time fromhome to an STF for patients in each community Rela-tive travel time was defined as the ratio of travel time toa PHC to travel time to an STFChina has two basic medical insurance schemes
Urban Employee Basic Medical Insurance and Urbanand Rural Resident Basic Medical Insurance (the medicalinsurance of integrating Urban Resident Basic MedicalInsurance and New Rural Cooperative Medical Schemeofficially in 2016) Insurance status affects out-of-pocketexpenses of patients differentially for seeking care fromPHCs and STFs Another critical factor affecting bypass-ing is patientsrsquo medical conditions especially the pres-ence of chronic conditions This analysis included anextensive list of chronic conditions including hyperten-sion dyslipidemia diabetes cancer chronic lung dis-eases liver disease heart diseases stroke emotionalnervous or psychiatric problems Definitions of the vari-ables are given in Table 1
Data analysisThis analysis is based on a sample of 10061 respon-dents who sought outpatient care during the 4 weeks

prior to the survey date Since follow-up visits maybias the results this study has estimated the modelsseparately for all visits (first visit and revisits) and thefirst visits The sample size for first visits for an epi-sode of illness was 4720 If the primary care providersin the first visits refer patients to specialists the sub-sequent visits may reflect physician recommendationsrather than patientsrsquo decision-making In other wordsat least some of the revisits may not be consideredbypassing of the PHCsLogistic regression models were employed to analyze
factors affecting propensity to bypass PHCs stratified byrural-urban residence Since access to health facilitiesdiffers significantly between rural and urban areas thestratification is important to avoid potential bias createdby rural-urban differences (see Table A1 of Additionalfile 1) The annex table also identifies a number of rele-vant variables for inclusion in the regression models Inmost panel studies the preferred empirical model wouldbe either the fixed-effects or the random-effects logisticmodel [37] and empirical results should guide the choicebetween the model-typesWhen estimating the patient fixed effects model
whenever patients bypass (or do not bypass) PHC in twowaves or all three waves by definition variations overtime becomes zero and the empirical model will dropthe cases In the full sample of the fixed effects logisticmodels 6620 out of 7672 rural patients and 2185 out of2389 urban patients were dropped because of lack ofinter-temporal variation The random-effects model usesall the available observations and allows estimation ofparameters and standard errors [40] This study usedHausmanrsquos specification test for the random effects lo-gistic regression models to test the orthogonality of therandom effects and the regressors [41] The Hausmantest suggests that the random-effects model is preferredover the fixed-effects model
ResultsAmong those who used outpatient services the percentof patients bypassing PHCs were 340 in Wave 1394 in Wave 2 and 418 in Wave 3 indicating an in-creasing trend of bypassing over the years In rural areasthe percent bypassing PHCs were 270 in Wave 1330 in Wave 2 and 346 in Wave 3 In contrast thepropensity to bypass PHCs remained almost static inurban areas over the years ndash 624 in Wave 1 611 inWave 2 and 601 in Wave 3 Urban patients werenearly twice as likely as rural patients to bypass PHCsThe results remained similar when only the first visitswere considered ie excluding the follow-up outpatientvisits Table A1 of Additional file 1 compares patientcharacteristics by bypassing behavior (patients bypassingPHCs vs those not bypassing) The results indicate thatbypassers differed from non-bypassers in terms of theirresidence educational attainment household incomemedical insurance coverage specific chronic conditionsand the incidence of hospitalizationThe odds ratios of the random effects logistic regres-
sion analysis are reported in Table 2 The results implythat rural patients aged 65 years or older were less likelyto bypass PHCs than patients in the age group 45ndash54years (OR = 064 p lt 0001) In contrast patients aged65 years or older show a higher probability of bypassingin urban areas (OR = 147 p = 0036) The probability ofbypassing PHCs increases with higher educational at-tainment in both rural and urban areas Compared toilliterate patients individuals who attended elementaryschool show increased odds of bypassing by 22 in ruralareas (OR = 122 p lt 0012) and completion of morethan 3 years of college increased the odds by 236 inurban areas (OR = 336 p lt 0001) Urban patients in thelower-middle income category were less likely to bypassPHCs than those with high income (OR = 056 p =0010) A similar trend was observed for patients in the

when only the first contact outpatient visits are used inthe estimation The results are similar to the estimatesobtained when all visits including the revisits were usedin the analysis
DiscussionThe nationally representative survey indicates that theproportion of outpatients bypassing PHCs increased overthe years in China Urban patients were nearly twice aslikely to bypass PHCs than rural patients This is not un-expected due to the easy access and availability of manySTFs in urban areas Travel distance and travel-relatedcosts are likely to be lower for the urban population [3642] Rural patients often must rely on PHCs in the areadue to the difficulty of accessing alternative health careproviders Especially for rural residents obtaining carefrom upper-level facilities may become quite expensivedue to higher out-of-pocket expenses and longer traveltimes [43]About two in five older adults in China bypassed
PHCs to obtain care from upper-level providers (STFs)
This is despite significantly lower out-of-pocket costs forservices and drugs at PHCs than at the STFs Thereforefinancial incentives have not been adequate to discour-age bypassing of PHCs in China The results imply thatpropensity to bypass PHCs is unlikely to decline signifi-cantly if the financial incentives in favor of PHCs aremade even stronger Given that the bypassing tendencyis related to age ruralurban location present of chronicconditions etc it points to supply-side concerns prob-ably related to availability and quality of service-mix of-fered at the PHCsThe random-effects logistic regression model identi-
fied several factors affecting bypassing of PHCs for ruraland urban residents separately The estimates suggestthat factors affecting the first visits are very similar tofactors affecting all outpatient visits (both new andfollow-up visits) implying that physician recommenda-tions were not important in influencing the choice offacility-types Regardless of rural-urban residence a rela-tive increase in travel time (ratio of travel times to PHCand STF) increased the probability of bypassing PHCsThe result is consistent with the findings in the litera-ture ie increased travel time lowers the utilization ofhealth care facilities [33 44ndash50] Without a formal refer-ral system in urban areas where health resources aremuch richer and STFs are more concentrated than thosein rural areas in China urban patients are more likely tobypass PHCs because of easy accessibility and availabilityof medical care services they needPatients with higher educational attainment show a
higher probability of bypassing PHCs Educational at-tainment is an indicator of socioeconomic status (SES)as well as knowledge about the relative quality of ser-vices facilities offer Middle-aged and older adults withhigher level of income are also more likely to bypassPHCs This probably indicates perception of lower qual-ity of services at the PHCs compared to the STFs Withan increase in income and educational attainment pa-tients become more sensitive to service quality and lesssensitive to cost savings that can be achieved by utilizingPHCsIn rural areas self-reported poor health status in-
creased the likelihood of bypassing PHCs Again thispossibly reflects a lack of confidence in the quality of

services andor non-availability of individualized servicesat the PHC [51 52] Offering individualized services is aperson-centered care approach [53] Patients who expe-rienced hospitalization in the past 12 months are morelikely to bypass PHCs as the hospitalization in the recentpast may be associated with actual or perceived higherseverity of illness or need for individualized services en-couraging utilization of STFs [29] A number of chronicconditions also affect the choice of facility-type Patientswith arthritis or rheumatism were less likely to bypassPHCs probably because these conditions make travelmore difficult [54] especially for rural patients who musttravel significantly longer distances to reach STFsOlder adults show high degree of bypassing PHCs in
urban areas but for rural areas the opposite was true(middle-aged individuals more likely to bypass than theolder adults) This tendency may be associated with lackof relevant services at the PHC level Older adults re-quire more personalized care and continuity of care isimportant for their health status In contrast for ruralareas social value of protecting the health of middle-aged individuals may be higher and travel to a STF ismore costly and difficult for the elderly Among urbanpatients older adults were more likely to bypass PHCsthan those aged 45ndash54 years Geriatric services have notbeen properly incorporated at the primary level in urbanChina [55] which may explain urban older adultsrsquo hesi-tancy to seek care from the PHCs Urban patients withdiabetes are also more likely to use upper-level facilitiesagain reflecting the lack of chronic disease managementat the primary level [56]In urban areas where the upper-level facilities are eas-
ily accessible the tendency to bypass is significantlyhigher With improvements in health status and theaging of the population patients need individualized aswell as continuity of care services Unless those servicesare offered from the PHCs bypassing problem is ex-pected to increase further [57 58]There are several limitations of this study The
CHARLS survey provides information only on the mostrecent outpatient service utilized in the previous 4weeks Measuring the incidence of bypassing using themost recent outpatient visits within the last 4 weeks may
bias the results The survey did not collect informationon facility and provider characteristics and the studycould not analyze the effect of provider characteristicson the choice of health facilities
ConclusionsAbout two in five older adults in China bypassed PHCsto obtain care from upper-level providers (STFs) Urbanpatients were twice as likely as rural patients to bypassPHCs The present study found that relative increase intravel time and more educated had a higher likelihoodof bypassing primary care in rural and urban areasMoreover poor health status and being hospitalized inthe past 12 months had a higher likelihood of bypassingprimary care in rural areas On the other hand arthritisor rheumatism decreased the odds of bypassing Further-more older age and diabetes had a higher likelihood ofbypassing primary care in urban areasContinuity of care and individualized attention require
redesigning the mode of care delivery at the PHC levelwith emphasis on patient-provider trust and adoption ofproactive health promotion and disease prevention Struc-tural changes including the staffing of the PHCs will beneeded to make the PHCs more effective in addressing theneeds of the elderly and middle-aged individuals The find-ings of the study indicate the importance of strengtheningthe service provision in rural PHCs to address commonchronic conditions In fact improving the service deliveryfor addressing the needs of chronic conditions will im-prove utilization of PHCs in both rural and urban areasIn conclusion improving the utilization of PHCs in
China will require improving the quality of services ren-dered from these facilities Perceived quality of medicalcare delivered from the PHCs can be improved if the facil-ities are able to offer comprehensive person-centeredhealth care focusing on the family health care needs andmaking critical screening and preventive services availableAvailability of services alone will not improve overall qual-ity of services ndash it will require a system of continuity ofcare by ensuring good rapport between patients and phy-sicians If patients feel that they have their own primarycare physician in the PHCs the likelihood of seeking carefrom PHCs should be significantly higher

Patients are less likely to bypass local health care pro-viders when the distance to alternative providers is rela-tively high (Tai et al [31] Escarce and Kapur [30] andLeonard et al [34]) Varkevisser and van der Geest [36]reported that distance is an important factor in thechoice of hospitals ie patients are less likely to bypassthe nearest hospital when travel time to the next-nearesthospital increasesUnderstanding the reasons for bypassing PHCs will
help design government policies on how to make thePHCs more effective at the local level Despite the im-portance of the topic only a few studies have analyzedthis phenomenon using large longitudinal datasets Thisstudy is an attempt to understand the factors affectingthe propensity to bypass PHCs in China despite thecost-advantages created by policy makers to encouragethe utilization of PHCs
MethodsTheoretical and empirical modelsPatients have options in terms of health facilities theycan use For this analysis the current study defines theoptions as either seeking care from the ldquoprimary carecenterrdquo in the locality (PHC) or choosing an alternativeldquosecondary or tertiary facilityrdquo (STF) Patients in theorywill choose a facility-type that provides them a higherlevel of utility (u) ie if ui(PHC) lt ui(STF) patient i islikely to seek care from secondary or tertiary health fa-cilities The literature suggests that the utility u() associ-ated with the use of a health facility type may depend onseveral factors including patient characteristics illnesstype facility characteristics costs associated with seekingcare health system design Since the choice has been de-fined as a dichotomous outcome this study can developthe model by considering the likelihood of not selectingPHC [p(~PHC)] Therefore the generalized model ofbypassing PHCs can be written as
p PHCeth THORN frac14 f ZCT RjXeth THORN
where X is a vector of individual characteristics (agegender income) Z is facility-specific characteristics (egfacility size technology availability perceived quality) Cis the out-of-pocket expenses associated with thefacility-types T is travel distances and R representsother factors (eg physician recommendations on choiceof facilities)Given patient characteristics choosing a health facility
will require comparing the relevant factors between thelocal facility and other potentially accessible facilities InChina utilization of PHCs will be less expensive thanobtaining care from upper-level facilities and insurancecoverage lowers the cost of using PHCs even furtherTherefore insurance status may be used as one of the
proxy variables of financial incentives to access PHCsHigher-tier facilities by definition provide more com-prehensive healthcare services using better equipmentand technology Therefore higher severity and relativelycomplex medical conditions may benefit from accessingcare from higher-tier facilities One important factor thataffects the choice of facilities is their relative distances Ifthe closest STF is located relatively far away from acommunity patients may elect to use PHC keepingother factors constant For empirical estimation the ra-tio of the distances to PHC and STFs may be used torepresent the relative degrees of accessibility of the facil-ities This ratio is expected to be less than 10 but thehigher the ratio the greater should be the likelihood ofbypassingFor the analysis of bypassing behavior the probability
of not using PHC [p(~PHC)] the first step was to carry-out simple descriptive analysis to understand the differ-ences between patients who bypass PHCs (bypassers)and those who do not (non-bypassers) Pearsonrsquos chi-square test was used to analyze the categorical inde-pendent variables For the multivariate analysis it is as-sumed that there is an unobserved latent variable yitaffecting the decision to bypass

Data sourceThe China Health and Retirement Longitudinal Study(CHARLS) conducted by the National School of Devel-opment of Peking University is the data set used for thisanalysis The sample of CHARLS was drawn from 450villages or urban communities of 150 counties or equiva-lent urban districts in 28 provinces A multistage strati-fied sampling with probability proportional to size wasused for the survey More details on the sampling anddata collection process are available in Zhao et al [38]The CHARLS is nationally representative and collectsdata from persons of age 45 years or older and theirspouses The CHARLS respondents are reinterviewedevery 2 years with the first wave in 2011 covering17705 persons and two follow-ups in 2013 and 2015with 18605 persons and 21095 persons respectivelyThe CHARLS questionnaires include questions onhousehold characteristics demographic backgroundhealth status and physical functioning health careutilization insurance status work retirement and pen-sion income expenditure asset ownership housingcharacteristics etc From the datasets only the individ-uals who sought outpatient care during the previous 4weeks before the date of interview were selected Thefinal sample consisted of a total of 10061 individuals inall three waves combined
MeasuresRural and urban definitionsIn the CHARLS each adult was asked ldquoWhat is the typeof your addressrdquo and ldquoIs it a rural village or urban com-munityrdquo All respondents were classified as either ruralor urban residents based on their responses
Dependent variableThe PHCs in China provide generalist clinical care andbasic public health services through community healthcenters and clinics in the urban areas and township hos-pitals and village clinics in the rural areas [13 39] Inthis study bypassing PHCs has been defined as skippingany primary care facilities to obtain care from the
secondary or tertiary level Responses to the followingsurvey questions were used to identify the incidence ofldquobypassingrdquo (1) Which healthcare provider did you visitmost recently during the past 4 weeks 1 General hos-pital 2 Specialized hospital 3 Chinese medicine hos-pital 4 Community healthcare center 5 Townshiphospital 6 Community health clinic 7 Village clinicPrivate clinic and 8 Other and (2) Did the providervisit you at home 1 Yes and 2 No If a respondent an-swered Question (1) by selecting any of General hospitalSpecialized hospital or Chinese medicine hospital andreported ldquoNordquo on Question (2) the patient is consideredto have had a ldquobypassingrdquo of the PHC The respondentswho reported using ldquoOtherrdquo providers in Question (1) orldquoYesrdquo to Question (2) were dropped from this studysample
Independent variablesIndependent variables were chosen based on theoreticalconsiderations and literature review The survey col-lected data on travel time to the facility for each of thepatients Therefore those who obtained care from PHCsreported travel time to the PHCs while those who vis-ited the upper-level facilities (STFs) reported travel timeto those facilities Reported travel times to facility-types(PHCs or STFs) were used to predict the travel times toPHCs and STFs for all patients living in a communitybut did not visit the facility-type The average travel timeto PHCs for patients living in a community for examplewas used to approximate the travel time of those livingin the same community but did not use the PHCs Thesame method was used to predict the travel time fromhome to an STF for patients in each community Rela-tive travel time was defined as the ratio of travel time toa PHC to travel time to an STFChina has two basic medical insurance schemes
Urban Employee Basic Medical Insurance and Urbanand Rural Resident Basic Medical Insurance (the medicalinsurance of integrating Urban Resident Basic MedicalInsurance and New Rural Cooperative Medical Schemeofficially in 2016) Insurance status affects out-of-pocketexpenses of patients differentially for seeking care fromPHCs and STFs Another critical factor affecting bypass-ing is patientsrsquo medical conditions especially the pres-ence of chronic conditions This analysis included anextensive list of chronic conditions including hyperten-sion dyslipidemia diabetes cancer chronic lung dis-eases liver disease heart diseases stroke emotionalnervous or psychiatric problems Definitions of the vari-ables are given in Table 1

prior to the survey date Since follow-up visits maybias the results this study has estimated the modelsseparately for all visits (first visit and revisits) and thefirst visits The sample size for first visits for an epi-sode of illness was 4720 If the primary care providersin the first visits refer patients to specialists the sub-sequent visits may reflect physician recommendationsrather than patientsrsquo decision-making In other wordsat least some of the revisits may not be consideredbypassing of the PHCsLogistic regression models were employed to analyze
factors affecting propensity to bypass PHCs stratified byrural-urban residence Since access to health facilitiesdiffers significantly between rural and urban areas thestratification is important to avoid potential bias createdby rural-urban differences (see Table A1 of Additionalfile 1) The annex table also identifies a number of rele-vant variables for inclusion in the regression models Inmost panel studies the preferred empirical model wouldbe either the fixed-effects or the random-effects logisticmodel [37] and empirical results should guide the choicebetween the model-typesWhen estimating the patient fixed effects model
whenever patients bypass (or do not bypass) PHC in twowaves or all three waves by definition variations overtime becomes zero and the empirical model will dropthe cases In the full sample of the fixed effects logisticmodels 6620 out of 7672 rural patients and 2185 out of2389 urban patients were dropped because of lack ofinter-temporal variation The random-effects model usesall the available observations and allows estimation ofparameters and standard errors [40] This study usedHausmanrsquos specification test for the random effects lo-gistic regression models to test the orthogonality of therandom effects and the regressors [41] The Hausmantest suggests that the random-effects model is preferredover the fixed-effects model
ResultsAmong those who used outpatient services the percentof patients bypassing PHCs were 340 in Wave 1394 in Wave 2 and 418 in Wave 3 indicating an in-creasing trend of bypassing over the years In rural areasthe percent bypassing PHCs were 270 in Wave 1330 in Wave 2 and 346 in Wave 3 In contrast thepropensity to bypass PHCs remained almost static inurban areas over the years ndash 624 in Wave 1 611 inWave 2 and 601 in Wave 3 Urban patients werenearly twice as likely as rural patients to bypass PHCsThe results remained similar when only the first visitswere considered ie excluding the follow-up outpatientvisits Table A1 of Additional file 1 compares patientcharacteristics by bypassing behavior (patients bypassingPHCs vs those not bypassing) The results indicate thatbypassers differed from non-bypassers in terms of theirresidence educational attainment household incomemedical insurance coverage specific chronic conditionsand the incidence of hospitalizationThe odds ratios of the random effects logistic regres-
sion analysis are reported in Table 2 The results implythat rural patients aged 65 years or older were less likelyto bypass PHCs than patients in the age group 45ndash54years (OR = 064 p lt 0001) In contrast patients aged65 years or older show a higher probability of bypassingin urban areas (OR = 147 p = 0036) The probability ofbypassing PHCs increases with higher educational at-tainment in both rural and urban areas Compared toilliterate patients individuals who attended elementaryschool show increased odds of bypassing by 22 in ruralareas (OR = 122 p lt 0012) and completion of morethan 3 years of college increased the odds by 236 inurban areas (OR = 336 p lt 0001) Urban patients in thelower-middle income category were less likely to bypassPHCs than those with high income (OR = 056 p =0010) A similar trend was observed for patients in the

when only the first contact outpatient visits are used inthe estimation The results are similar to the estimatesobtained when all visits including the revisits were usedin the analysis
DiscussionThe nationally representative survey indicates that theproportion of outpatients bypassing PHCs increased overthe years in China Urban patients were nearly twice aslikely to bypass PHCs than rural patients This is not un-expected due to the easy access and availability of manySTFs in urban areas Travel distance and travel-relatedcosts are likely to be lower for the urban population [3642] Rural patients often must rely on PHCs in the areadue to the difficulty of accessing alternative health careproviders Especially for rural residents obtaining carefrom upper-level facilities may become quite expensivedue to higher out-of-pocket expenses and longer traveltimes [43]About two in five older adults in China bypassed
PHCs to obtain care from upper-level providers (STFs)
This is despite significantly lower out-of-pocket costs forservices and drugs at PHCs than at the STFs Thereforefinancial incentives have not been adequate to discour-age bypassing of PHCs in China The results imply thatpropensity to bypass PHCs is unlikely to decline signifi-cantly if the financial incentives in favor of PHCs aremade even stronger Given that the bypassing tendencyis related to age ruralurban location present of chronicconditions etc it points to supply-side concerns prob-ably related to availability and quality of service-mix of-fered at the PHCsThe random-effects logistic regression model identi-
fied several factors affecting bypassing of PHCs for ruraland urban residents separately The estimates suggestthat factors affecting the first visits are very similar tofactors affecting all outpatient visits (both new andfollow-up visits) implying that physician recommenda-tions were not important in influencing the choice offacility-types Regardless of rural-urban residence a rela-tive increase in travel time (ratio of travel times to PHCand STF) increased the probability of bypassing PHCsThe result is consistent with the findings in the litera-ture ie increased travel time lowers the utilization ofhealth care facilities [33 44ndash50] Without a formal refer-ral system in urban areas where health resources aremuch richer and STFs are more concentrated than thosein rural areas in China urban patients are more likely tobypass PHCs because of easy accessibility and availabilityof medical care services they needPatients with higher educational attainment show a
higher probability of bypassing PHCs Educational at-tainment is an indicator of socioeconomic status (SES)as well as knowledge about the relative quality of ser-vices facilities offer Middle-aged and older adults withhigher level of income are also more likely to bypassPHCs This probably indicates perception of lower qual-ity of services at the PHCs compared to the STFs Withan increase in income and educational attainment pa-tients become more sensitive to service quality and lesssensitive to cost savings that can be achieved by utilizingPHCsIn rural areas self-reported poor health status in-
creased the likelihood of bypassing PHCs Again thispossibly reflects a lack of confidence in the quality of

services andor non-availability of individualized servicesat the PHC [51 52] Offering individualized services is aperson-centered care approach [53] Patients who expe-rienced hospitalization in the past 12 months are morelikely to bypass PHCs as the hospitalization in the recentpast may be associated with actual or perceived higherseverity of illness or need for individualized services en-couraging utilization of STFs [29] A number of chronicconditions also affect the choice of facility-type Patientswith arthritis or rheumatism were less likely to bypassPHCs probably because these conditions make travelmore difficult [54] especially for rural patients who musttravel significantly longer distances to reach STFsOlder adults show high degree of bypassing PHCs in
urban areas but for rural areas the opposite was true(middle-aged individuals more likely to bypass than theolder adults) This tendency may be associated with lackof relevant services at the PHC level Older adults re-quire more personalized care and continuity of care isimportant for their health status In contrast for ruralareas social value of protecting the health of middle-aged individuals may be higher and travel to a STF ismore costly and difficult for the elderly Among urbanpatients older adults were more likely to bypass PHCsthan those aged 45ndash54 years Geriatric services have notbeen properly incorporated at the primary level in urbanChina [55] which may explain urban older adultsrsquo hesi-tancy to seek care from the PHCs Urban patients withdiabetes are also more likely to use upper-level facilitiesagain reflecting the lack of chronic disease managementat the primary level [56]In urban areas where the upper-level facilities are eas-
ily accessible the tendency to bypass is significantlyhigher With improvements in health status and theaging of the population patients need individualized aswell as continuity of care services Unless those servicesare offered from the PHCs bypassing problem is ex-pected to increase further [57 58]There are several limitations of this study The
CHARLS survey provides information only on the mostrecent outpatient service utilized in the previous 4weeks Measuring the incidence of bypassing using themost recent outpatient visits within the last 4 weeks may
bias the results The survey did not collect informationon facility and provider characteristics and the studycould not analyze the effect of provider characteristicson the choice of health facilities
ConclusionsAbout two in five older adults in China bypassed PHCsto obtain care from upper-level providers (STFs) Urbanpatients were twice as likely as rural patients to bypassPHCs The present study found that relative increase intravel time and more educated had a higher likelihoodof bypassing primary care in rural and urban areasMoreover poor health status and being hospitalized inthe past 12 months had a higher likelihood of bypassingprimary care in rural areas On the other hand arthritisor rheumatism decreased the odds of bypassing Further-more older age and diabetes had a higher likelihood ofbypassing primary care in urban areasContinuity of care and individualized attention require
redesigning the mode of care delivery at the PHC levelwith emphasis on patient-provider trust and adoption ofproactive health promotion and disease prevention Struc-tural changes including the staffing of the PHCs will beneeded to make the PHCs more effective in addressing theneeds of the elderly and middle-aged individuals The find-ings of the study indicate the importance of strengtheningthe service provision in rural PHCs to address commonchronic conditions In fact improving the service deliveryfor addressing the needs of chronic conditions will im-prove utilization of PHCs in both rural and urban areasIn conclusion improving the utilization of PHCs in
China will require improving the quality of services ren-dered from these facilities Perceived quality of medicalcare delivered from the PHCs can be improved if the facil-ities are able to offer comprehensive person-centeredhealth care focusing on the family health care needs andmaking critical screening and preventive services availableAvailability of services alone will not improve overall qual-ity of services ndash it will require a system of continuity ofcare by ensuring good rapport between patients and phy-sicians If patients feel that they have their own primarycare physician in the PHCs the likelihood of seeking carefrom PHCs should be significantly higher

Data sourceThe China Health and Retirement Longitudinal Study(CHARLS) conducted by the National School of Devel-opment of Peking University is the data set used for thisanalysis The sample of CHARLS was drawn from 450villages or urban communities of 150 counties or equiva-lent urban districts in 28 provinces A multistage strati-fied sampling with probability proportional to size wasused for the survey More details on the sampling anddata collection process are available in Zhao et al [38]The CHARLS is nationally representative and collectsdata from persons of age 45 years or older and theirspouses The CHARLS respondents are reinterviewedevery 2 years with the first wave in 2011 covering17705 persons and two follow-ups in 2013 and 2015with 18605 persons and 21095 persons respectivelyThe CHARLS questionnaires include questions onhousehold characteristics demographic backgroundhealth status and physical functioning health careutilization insurance status work retirement and pen-sion income expenditure asset ownership housingcharacteristics etc From the datasets only the individ-uals who sought outpatient care during the previous 4weeks before the date of interview were selected Thefinal sample consisted of a total of 10061 individuals inall three waves combined
MeasuresRural and urban definitionsIn the CHARLS each adult was asked ldquoWhat is the typeof your addressrdquo and ldquoIs it a rural village or urban com-munityrdquo All respondents were classified as either ruralor urban residents based on their responses
Dependent variableThe PHCs in China provide generalist clinical care andbasic public health services through community healthcenters and clinics in the urban areas and township hos-pitals and village clinics in the rural areas [13 39] Inthis study bypassing PHCs has been defined as skippingany primary care facilities to obtain care from the
secondary or tertiary level Responses to the followingsurvey questions were used to identify the incidence ofldquobypassingrdquo (1) Which healthcare provider did you visitmost recently during the past 4 weeks 1 General hos-pital 2 Specialized hospital 3 Chinese medicine hos-pital 4 Community healthcare center 5 Townshiphospital 6 Community health clinic 7 Village clinicPrivate clinic and 8 Other and (2) Did the providervisit you at home 1 Yes and 2 No If a respondent an-swered Question (1) by selecting any of General hospitalSpecialized hospital or Chinese medicine hospital andreported ldquoNordquo on Question (2) the patient is consideredto have had a ldquobypassingrdquo of the PHC The respondentswho reported using ldquoOtherrdquo providers in Question (1) orldquoYesrdquo to Question (2) were dropped from this studysample
Independent variablesIndependent variables were chosen based on theoreticalconsiderations and literature review The survey col-lected data on travel time to the facility for each of thepatients Therefore those who obtained care from PHCsreported travel time to the PHCs while those who vis-ited the upper-level facilities (STFs) reported travel timeto those facilities Reported travel times to facility-types(PHCs or STFs) were used to predict the travel times toPHCs and STFs for all patients living in a communitybut did not visit the facility-type The average travel timeto PHCs for patients living in a community for examplewas used to approximate the travel time of those livingin the same community but did not use the PHCs Thesame method was used to predict the travel time fromhome to an STF for patients in each community Rela-tive travel time was defined as the ratio of travel time toa PHC to travel time to an STFChina has two basic medical insurance schemes
Urban Employee Basic Medical Insurance and Urbanand Rural Resident Basic Medical Insurance (the medicalinsurance of integrating Urban Resident Basic MedicalInsurance and New Rural Cooperative Medical Schemeofficially in 2016) Insurance status affects out-of-pocketexpenses of patients differentially for seeking care fromPHCs and STFs Another critical factor affecting bypass-ing is patientsrsquo medical conditions especially the pres-ence of chronic conditions This analysis included anextensive list of chronic conditions including hyperten-sion dyslipidemia diabetes cancer chronic lung dis-eases liver disease heart diseases stroke emotionalnervous or psychiatric problems Definitions of the vari-ables are given in Table 1
Data analysisThis analysis is based on a sample of 10061 respon-dents who sought outpatient care during the 4 weeks

prior to the survey date Since follow-up visits maybias the results this study has estimated the modelsseparately for all visits (first visit and revisits) and thefirst visits The sample size for first visits for an epi-sode of illness was 4720 If the primary care providersin the first visits refer patients to specialists the sub-sequent visits may reflect physician recommendationsrather than patientsrsquo decision-making In other wordsat least some of the revisits may not be consideredbypassing of the PHCsLogistic regression models were employed to analyze
factors affecting propensity to bypass PHCs stratified byrural-urban residence Since access to health facilitiesdiffers significantly between rural and urban areas thestratification is important to avoid potential bias createdby rural-urban differences (see Table A1 of Additionalfile 1) The annex table also identifies a number of rele-vant variables for inclusion in the regression models Inmost panel studies the preferred empirical model wouldbe either the fixed-effects or the random-effects logisticmodel [37] and empirical results should guide the choicebetween the model-typesWhen estimating the patient fixed effects model
whenever patients bypass (or do not bypass) PHC in twowaves or all three waves by definition variations overtime becomes zero and the empirical model will dropthe cases In the full sample of the fixed effects logisticmodels 6620 out of 7672 rural patients and 2185 out of2389 urban patients were dropped because of lack ofinter-temporal variation The random-effects model usesall the available observations and allows estimation ofparameters and standard errors [40] This study usedHausmanrsquos specification test for the random effects lo-gistic regression models to test the orthogonality of therandom effects and the regressors [41] The Hausmantest suggests that the random-effects model is preferredover the fixed-effects model
ResultsAmong those who used outpatient services the percentof patients bypassing PHCs were 340 in Wave 1394 in Wave 2 and 418 in Wave 3 indicating an in-creasing trend of bypassing over the years In rural areasthe percent bypassing PHCs were 270 in Wave 1330 in Wave 2 and 346 in Wave 3 In contrast thepropensity to bypass PHCs remained almost static inurban areas over the years ndash 624 in Wave 1 611 inWave 2 and 601 in Wave 3 Urban patients werenearly twice as likely as rural patients to bypass PHCsThe results remained similar when only the first visitswere considered ie excluding the follow-up outpatientvisits Table A1 of Additional file 1 compares patientcharacteristics by bypassing behavior (patients bypassingPHCs vs those not bypassing) The results indicate thatbypassers differed from non-bypassers in terms of theirresidence educational attainment household incomemedical insurance coverage specific chronic conditionsand the incidence of hospitalizationThe odds ratios of the random effects logistic regres-
sion analysis are reported in Table 2 The results implythat rural patients aged 65 years or older were less likelyto bypass PHCs than patients in the age group 45ndash54years (OR = 064 p lt 0001) In contrast patients aged65 years or older show a higher probability of bypassingin urban areas (OR = 147 p = 0036) The probability ofbypassing PHCs increases with higher educational at-tainment in both rural and urban areas Compared toilliterate patients individuals who attended elementaryschool show increased odds of bypassing by 22 in ruralareas (OR = 122 p lt 0012) and completion of morethan 3 years of college increased the odds by 236 inurban areas (OR = 336 p lt 0001) Urban patients in thelower-middle income category were less likely to bypassPHCs than those with high income (OR = 056 p =0010) A similar trend was observed for patients in the

upper-middle income category (OR = 069 p = 0018)Rural patients enrolled in Urban Employee Basic Med-ical Insurance had three times the odds (OR = 301 p lt0001) of bypassing PHCs than the uninsured Comparedwith the uninsured patients urban patients enrolled inNew Rural Cooperative Medical Scheme had a lowerodds of bypassing (OR = 047 p = 0012)Rural patients with poor health were more likely to by-
pass PHCs than those who reported their health beinglsquofairrsquo (OR = 134 p lt 0001) Patients with heart diseasesin rural areas and urban patients with diabetes had ahigher odds of bypassing PHCs (OR = 140 p = 0001OR = 176 p = 0009) and the opposite was true for ruralpatients with arthritis or rheumatism and patients withother major chronic conditions in urban areas (OR =083 p = 0006 OR = 064 p = 0015) Patients who expe-rienced hospitalization in the past 12 months had ahigher odds of bypassing in both the rural and urbanareas (OR = 208 p lt 0001 OR = 215 p lt 0001) Rela-tive travel time was positively associated with patientsbypassing PHCs in rural and urban areas (OR = 115 p lt0001 OR = 128 p lt 0001)Table 3 presents factors affecting bypassing PHCs
when only the first contact outpatient visits are used inthe estimation The results are similar to the estimatesobtained when all visits including the revisits were usedin the analysis
DiscussionThe nationally representative survey indicates that theproportion of outpatients bypassing PHCs increased overthe years in China Urban patients were nearly twice aslikely to bypass PHCs than rural patients This is not un-expected due to the easy access and availability of manySTFs in urban areas Travel distance and travel-relatedcosts are likely to be lower for the urban population [3642] Rural patients often must rely on PHCs in the areadue to the difficulty of accessing alternative health careproviders Especially for rural residents obtaining carefrom upper-level facilities may become quite expensivedue to higher out-of-pocket expenses and longer traveltimes [43]About two in five older adults in China bypassed
PHCs to obtain care from upper-level providers (STFs)
This is despite significantly lower out-of-pocket costs forservices and drugs at PHCs than at the STFs Thereforefinancial incentives have not been adequate to discour-age bypassing of PHCs in China The results imply thatpropensity to bypass PHCs is unlikely to decline signifi-cantly if the financial incentives in favor of PHCs aremade even stronger Given that the bypassing tendencyis related to age ruralurban location present of chronicconditions etc it points to supply-side concerns prob-ably related to availability and quality of service-mix of-fered at the PHCsThe random-effects logistic regression model identi-
fied several factors affecting bypassing of PHCs for ruraland urban residents separately The estimates suggestthat factors affecting the first visits are very similar tofactors affecting all outpatient visits (both new andfollow-up visits) implying that physician recommenda-tions were not important in influencing the choice offacility-types Regardless of rural-urban residence a rela-tive increase in travel time (ratio of travel times to PHCand STF) increased the probability of bypassing PHCsThe result is consistent with the findings in the litera-ture ie increased travel time lowers the utilization ofhealth care facilities [33 44ndash50] Without a formal refer-ral system in urban areas where health resources aremuch richer and STFs are more concentrated than thosein rural areas in China urban patients are more likely tobypass PHCs because of easy accessibility and availabilityof medical care services they needPatients with higher educational attainment show a
higher probability of bypassing PHCs Educational at-tainment is an indicator of socioeconomic status (SES)as well as knowledge about the relative quality of ser-vices facilities offer Middle-aged and older adults withhigher level of income are also more likely to bypassPHCs This probably indicates perception of lower qual-ity of services at the PHCs compared to the STFs Withan increase in income and educational attainment pa-tients become more sensitive to service quality and lesssensitive to cost savings that can be achieved by utilizingPHCsIn rural areas self-reported poor health status in-
creased the likelihood of bypassing PHCs Again thispossibly reflects a lack of confidence in the quality of

services andor non-availability of individualized servicesat the PHC [51 52] Offering individualized services is aperson-centered care approach [53] Patients who expe-rienced hospitalization in the past 12 months are morelikely to bypass PHCs as the hospitalization in the recentpast may be associated with actual or perceived higherseverity of illness or need for individualized services en-couraging utilization of STFs [29] A number of chronicconditions also affect the choice of facility-type Patientswith arthritis or rheumatism were less likely to bypassPHCs probably because these conditions make travelmore difficult [54] especially for rural patients who musttravel significantly longer distances to reach STFsOlder adults show high degree of bypassing PHCs in
urban areas but for rural areas the opposite was true(middle-aged individuals more likely to bypass than theolder adults) This tendency may be associated with lackof relevant services at the PHC level Older adults re-quire more personalized care and continuity of care isimportant for their health status In contrast for ruralareas social value of protecting the health of middle-aged individuals may be higher and travel to a STF ismore costly and difficult for the elderly Among urbanpatients older adults were more likely to bypass PHCsthan those aged 45ndash54 years Geriatric services have notbeen properly incorporated at the primary level in urbanChina [55] which may explain urban older adultsrsquo hesi-tancy to seek care from the PHCs Urban patients withdiabetes are also more likely to use upper-level facilitiesagain reflecting the lack of chronic disease managementat the primary level [56]In urban areas where the upper-level facilities are eas-
ily accessible the tendency to bypass is significantlyhigher With improvements in health status and theaging of the population patients need individualized aswell as continuity of care services Unless those servicesare offered from the PHCs bypassing problem is ex-pected to increase further [57 58]There are several limitations of this study The
CHARLS survey provides information only on the mostrecent outpatient service utilized in the previous 4weeks Measuring the incidence of bypassing using themost recent outpatient visits within the last 4 weeks may
bias the results The survey did not collect informationon facility and provider characteristics and the studycould not analyze the effect of provider characteristicson the choice of health facilities
ConclusionsAbout two in five older adults in China bypassed PHCsto obtain care from upper-level providers (STFs) Urbanpatients were twice as likely as rural patients to bypassPHCs The present study found that relative increase intravel time and more educated had a higher likelihoodof bypassing primary care in rural and urban areasMoreover poor health status and being hospitalized inthe past 12 months had a higher likelihood of bypassingprimary care in rural areas On the other hand arthritisor rheumatism decreased the odds of bypassing Further-more older age and diabetes had a higher likelihood ofbypassing primary care in urban areasContinuity of care and individualized attention require
redesigning the mode of care delivery at the PHC levelwith emphasis on patient-provider trust and adoption ofproactive health promotion and disease prevention Struc-tural changes including the staffing of the PHCs will beneeded to make the PHCs more effective in addressing theneeds of the elderly and middle-aged individuals The find-ings of the study indicate the importance of strengtheningthe service provision in rural PHCs to address commonchronic conditions In fact improving the service deliveryfor addressing the needs of chronic conditions will im-prove utilization of PHCs in both rural and urban areasIn conclusion improving the utilization of PHCs in
China will require improving the quality of services ren-dered from these facilities Perceived quality of medicalcare delivered from the PHCs can be improved if the facil-ities are able to offer comprehensive person-centeredhealth care focusing on the family health care needs andmaking critical screening and preventive services availableAvailability of services alone will not improve overall qual-ity of services ndash it will require a system of continuity ofcare by ensuring good rapport between patients and phy-sicians If patients feel that they have their own primarycare physician in the PHCs the likelihood of seeking carefrom PHCs should be significantly higher

prior to the survey date Since follow-up visits maybias the results this study has estimated the modelsseparately for all visits (first visit and revisits) and thefirst visits The sample size for first visits for an epi-sode of illness was 4720 If the primary care providersin the first visits refer patients to specialists the sub-sequent visits may reflect physician recommendationsrather than patientsrsquo decision-making In other wordsat least some of the revisits may not be consideredbypassing of the PHCsLogistic regression models were employed to analyze
factors affecting propensity to bypass PHCs stratified byrural-urban residence Since access to health facilitiesdiffers significantly between rural and urban areas thestratification is important to avoid potential bias createdby rural-urban differences (see Table A1 of Additionalfile 1) The annex table also identifies a number of rele-vant variables for inclusion in the regression models Inmost panel studies the preferred empirical model wouldbe either the fixed-effects or the random-effects logisticmodel [37] and empirical results should guide the choicebetween the model-typesWhen estimating the patient fixed effects model
whenever patients bypass (or do not bypass) PHC in twowaves or all three waves by definition variations overtime becomes zero and the empirical model will dropthe cases In the full sample of the fixed effects logisticmodels 6620 out of 7672 rural patients and 2185 out of2389 urban patients were dropped because of lack ofinter-temporal variation The random-effects model usesall the available observations and allows estimation ofparameters and standard errors [40] This study usedHausmanrsquos specification test for the random effects lo-gistic regression models to test the orthogonality of therandom effects and the regressors [41] The Hausmantest suggests that the random-effects model is preferredover the fixed-effects model
ResultsAmong those who used outpatient services the percentof patients bypassing PHCs were 340 in Wave 1394 in Wave 2 and 418 in Wave 3 indicating an in-creasing trend of bypassing over the years In rural areasthe percent bypassing PHCs were 270 in Wave 1330 in Wave 2 and 346 in Wave 3 In contrast thepropensity to bypass PHCs remained almost static inurban areas over the years ndash 624 in Wave 1 611 inWave 2 and 601 in Wave 3 Urban patients werenearly twice as likely as rural patients to bypass PHCsThe results remained similar when only the first visitswere considered ie excluding the follow-up outpatientvisits Table A1 of Additional file 1 compares patientcharacteristics by bypassing behavior (patients bypassingPHCs vs those not bypassing) The results indicate thatbypassers differed from non-bypassers in terms of theirresidence educational attainment household incomemedical insurance coverage specific chronic conditionsand the incidence of hospitalizationThe odds ratios of the random effects logistic regres-
sion analysis are reported in Table 2 The results implythat rural patients aged 65 years or older were less likelyto bypass PHCs than patients in the age group 45ndash54years (OR = 064 p lt 0001) In contrast patients aged65 years or older show a higher probability of bypassingin urban areas (OR = 147 p = 0036) The probability ofbypassing PHCs increases with higher educational at-tainment in both rural and urban areas Compared toilliterate patients individuals who attended elementaryschool show increased odds of bypassing by 22 in ruralareas (OR = 122 p lt 0012) and completion of morethan 3 years of college increased the odds by 236 inurban areas (OR = 336 p lt 0001) Urban patients in thelower-middle income category were less likely to bypassPHCs than those with high income (OR = 056 p =0010) A similar trend was observed for patients in the

upper-middle income category (OR = 069 p = 0018)Rural patients enrolled in Urban Employee Basic Med-ical Insurance had three times the odds (OR = 301 p lt0001) of bypassing PHCs than the uninsured Comparedwith the uninsured patients urban patients enrolled inNew Rural Cooperative Medical Scheme had a lowerodds of bypassing (OR = 047 p = 0012)Rural patients with poor health were more likely to by-
pass PHCs than those who reported their health beinglsquofairrsquo (OR = 134 p lt 0001) Patients with heart diseasesin rural areas and urban patients with diabetes had ahigher odds of bypassing PHCs (OR = 140 p = 0001OR = 176 p = 0009) and the opposite was true for ruralpatients with arthritis or rheumatism and patients withother major chronic conditions in urban areas (OR =083 p = 0006 OR = 064 p = 0015) Patients who expe-rienced hospitalization in the past 12 months had ahigher odds of bypassing in both the rural and urbanareas (OR = 208 p lt 0001 OR = 215 p lt 0001) Rela-tive travel time was positively associated with patientsbypassing PHCs in rural and urban areas (OR = 115 p lt0001 OR = 128 p lt 0001)Table 3 presents factors affecting bypassing PHCs
when only the first contact outpatient visits are used inthe estimation The results are similar to the estimatesobtained when all visits including the revisits were usedin the analysis
DiscussionThe nationally representative survey indicates that theproportion of outpatients bypassing PHCs increased overthe years in China Urban patients were nearly twice aslikely to bypass PHCs than rural patients This is not un-expected due to the easy access and availability of manySTFs in urban areas Travel distance and travel-relatedcosts are likely to be lower for the urban population [3642] Rural patients often must rely on PHCs in the areadue to the difficulty of accessing alternative health careproviders Especially for rural residents obtaining carefrom upper-level facilities may become quite expensivedue to higher out-of-pocket expenses and longer traveltimes [43]About two in five older adults in China bypassed
PHCs to obtain care from upper-level providers (STFs)
This is despite significantly lower out-of-pocket costs forservices and drugs at PHCs than at the STFs Thereforefinancial incentives have not been adequate to discour-age bypassing of PHCs in China The results imply thatpropensity to bypass PHCs is unlikely to decline signifi-cantly if the financial incentives in favor of PHCs aremade even stronger Given that the bypassing tendencyis related to age ruralurban location present of chronicconditions etc it points to supply-side concerns prob-ably related to availability and quality of service-mix of-fered at the PHCsThe random-effects logistic regression model identi-
fied several factors affecting bypassing of PHCs for ruraland urban residents separately The estimates suggestthat factors affecting the first visits are very similar tofactors affecting all outpatient visits (both new andfollow-up visits) implying that physician recommenda-tions were not important in influencing the choice offacility-types Regardless of rural-urban residence a rela-tive increase in travel time (ratio of travel times to PHCand STF) increased the probability of bypassing PHCsThe result is consistent with the findings in the litera-ture ie increased travel time lowers the utilization ofhealth care facilities [33 44ndash50] Without a formal refer-ral system in urban areas where health resources aremuch richer and STFs are more concentrated than thosein rural areas in China urban patients are more likely tobypass PHCs because of easy accessibility and availabilityof medical care services they needPatients with higher educational attainment show a
higher probability of bypassing PHCs Educational at-tainment is an indicator of socioeconomic status (SES)as well as knowledge about the relative quality of ser-vices facilities offer Middle-aged and older adults withhigher level of income are also more likely to bypassPHCs This probably indicates perception of lower qual-ity of services at the PHCs compared to the STFs Withan increase in income and educational attainment pa-tients become more sensitive to service quality and lesssensitive to cost savings that can be achieved by utilizingPHCsIn rural areas self-reported poor health status in-
creased the likelihood of bypassing PHCs Again thispossibly reflects a lack of confidence in the quality of

services andor non-availability of individualized servicesat the PHC [51 52] Offering individualized services is aperson-centered care approach [53] Patients who expe-rienced hospitalization in the past 12 months are morelikely to bypass PHCs as the hospitalization in the recentpast may be associated with actual or perceived higherseverity of illness or need for individualized services en-couraging utilization of STFs [29] A number of chronicconditions also affect the choice of facility-type Patientswith arthritis or rheumatism were less likely to bypassPHCs probably because these conditions make travelmore difficult [54] especially for rural patients who musttravel significantly longer distances to reach STFsOlder adults show high degree of bypassing PHCs in
urban areas but for rural areas the opposite was true(middle-aged individuals more likely to bypass than theolder adults) This tendency may be associated with lackof relevant services at the PHC level Older adults re-quire more personalized care and continuity of care isimportant for their health status In contrast for ruralareas social value of protecting the health of middle-aged individuals may be higher and travel to a STF ismore costly and difficult for the elderly Among urbanpatients older adults were more likely to bypass PHCsthan those aged 45ndash54 years Geriatric services have notbeen properly incorporated at the primary level in urbanChina [55] which may explain urban older adultsrsquo hesi-tancy to seek care from the PHCs Urban patients withdiabetes are also more likely to use upper-level facilitiesagain reflecting the lack of chronic disease managementat the primary level [56]In urban areas where the upper-level facilities are eas-
ily accessible the tendency to bypass is significantlyhigher With improvements in health status and theaging of the population patients need individualized aswell as continuity of care services Unless those servicesare offered from the PHCs bypassing problem is ex-pected to increase further [57 58]There are several limitations of this study The
CHARLS survey provides information only on the mostrecent outpatient service utilized in the previous 4weeks Measuring the incidence of bypassing using themost recent outpatient visits within the last 4 weeks may
bias the results The survey did not collect informationon facility and provider characteristics and the studycould not analyze the effect of provider characteristicson the choice of health facilities
ConclusionsAbout two in five older adults in China bypassed PHCsto obtain care from upper-level providers (STFs) Urbanpatients were twice as likely as rural patients to bypassPHCs The present study found that relative increase intravel time and more educated had a higher likelihoodof bypassing primary care in rural and urban areasMoreover poor health status and being hospitalized inthe past 12 months had a higher likelihood of bypassingprimary care in rural areas On the other hand arthritisor rheumatism decreased the odds of bypassing Further-more older age and diabetes had a higher likelihood ofbypassing primary care in urban areasContinuity of care and individualized attention require
redesigning the mode of care delivery at the PHC levelwith emphasis on patient-provider trust and adoption ofproactive health promotion and disease prevention Struc-tural changes including the staffing of the PHCs will beneeded to make the PHCs more effective in addressing theneeds of the elderly and middle-aged individuals The find-ings of the study indicate the importance of strengtheningthe service provision in rural PHCs to address commonchronic conditions In fact improving the service deliveryfor addressing the needs of chronic conditions will im-prove utilization of PHCs in both rural and urban areasIn conclusion improving the utilization of PHCs in
China will require improving the quality of services ren-dered from these facilities Perceived quality of medicalcare delivered from the PHCs can be improved if the facil-ities are able to offer comprehensive person-centeredhealth care focusing on the family health care needs andmaking critical screening and preventive services availableAvailability of services alone will not improve overall qual-ity of services ndash it will require a system of continuity ofcare by ensuring good rapport between patients and phy-sicians If patients feel that they have their own primarycare physician in the PHCs the likelihood of seeking carefrom PHCs should be significantly higher

prior to the survey date Since follow-up visits maybias the results this study has estimated the modelsseparately for all visits (first visit and revisits) and thefirst visits The sample size for first visits for an epi-sode of illness was 4720 If the primary care providersin the first visits refer patients to specialists the sub-sequent visits may reflect physician recommendationsrather than patientsrsquo decision-making In other wordsat least some of the revisits may not be consideredbypassing of the PHCsLogistic regression models were employed to analyze
factors affecting propensity to bypass PHCs stratified byrural-urban residence Since access to health facilitiesdiffers significantly between rural and urban areas thestratification is important to avoid potential bias createdby rural-urban differences (see Table A1 of Additionalfile 1) The annex table also identifies a number of rele-vant variables for inclusion in the regression models Inmost panel studies the preferred empirical model wouldbe either the fixed-effects or the random-effects logisticmodel [37] and empirical results should guide the choicebetween the model-typesWhen estimating the patient fixed effects model
whenever patients bypass (or do not bypass) PHC in twowaves or all three waves by definition variations overtime becomes zero and the empirical model will dropthe cases In the full sample of the fixed effects logisticmodels 6620 out of 7672 rural patients and 2185 out of2389 urban patients were dropped because of lack ofinter-temporal variation The random-effects model usesall the available observations and allows estimation ofparameters and standard errors [40] This study usedHausmanrsquos specification test for the random effects lo-gistic regression models to test the orthogonality of therandom effects and the regressors [41] The Hausmantest suggests that the random-effects model is preferredover the fixed-effects model
ResultsAmong those who used outpatient services the percentof patients bypassing PHCs were 340 in Wave 1394 in Wave 2 and 418 in Wave 3 indicating an in-creasing trend of bypassing over the years In rural areasthe percent bypassing PHCs were 270 in Wave 1330 in Wave 2 and 346 in Wave 3 In contrast thepropensity to bypass PHCs remained almost static inurban areas over the years ndash 624 in Wave 1 611 inWave 2 and 601 in Wave 3 Urban patients werenearly twice as likely as rural patients to bypass PHCsThe results remained similar when only the first visitswere considered ie excluding the follow-up outpatientvisits Table A1 of Additional file 1 compares patientcharacteristics by bypassing behavior (patients bypassingPHCs vs those not bypassing) The results indicate thatbypassers differed from non-bypassers in terms of theirresidence educational attainment household incomemedical insurance coverage specific chronic conditionsand the incidence of hospitalizationThe odds ratios of the random effects logistic regres-
sion analysis are reported in Table 2 The results implythat rural patients aged 65 years or older were less likelyto bypass PHCs than patients in the age group 45ndash54years (OR = 064 p lt 0001) In contrast patients aged65 years or older show a higher probability of bypassingin urban areas (OR = 147 p = 0036) The probability ofbypassing PHCs increases with higher educational at-tainment in both rural and urban areas Compared toilliterate patients individuals who attended elementaryschool show increased odds of bypassing by 22 in ruralareas (OR = 122 p lt 0012) and completion of morethan 3 years of college increased the odds by 236 inurban areas (OR = 336 p lt 0001) Urban patients in thelower-middle income category were less likely to bypassPHCs than those with high income (OR = 056 p =0010) A similar trend was observed for patients in the

upper-middle income category (OR = 069 p = 0018)Rural patients enrolled in Urban Employee Basic Med-ical Insurance had three times the odds (OR = 301 p lt0001) of bypassing PHCs than the uninsured Comparedwith the uninsured patients urban patients enrolled inNew Rural Cooperative Medical Scheme had a lowerodds of bypassing (OR = 047 p = 0012)Rural patients with poor health were more likely to by-
pass PHCs than those who reported their health beinglsquofairrsquo (OR = 134 p lt 0001) Patients with heart diseasesin rural areas and urban patients with diabetes had ahigher odds of bypassing PHCs (OR = 140 p = 0001OR = 176 p = 0009) and the opposite was true for ruralpatients with arthritis or rheumatism and patients withother major chronic conditions in urban areas (OR =083 p = 0006 OR = 064 p = 0015) Patients who expe-rienced hospitalization in the past 12 months had ahigher odds of bypassing in both the rural and urbanareas (OR = 208 p lt 0001 OR = 215 p lt 0001) Rela-tive travel time was positively associated with patientsbypassing PHCs in rural and urban areas (OR = 115 p lt0001 OR = 128 p lt 0001)Table 3 presents factors affecting bypassing PHCs
when only the first contact outpatient visits are used inthe estimation The results are similar to the estimatesobtained when all visits including the revisits were usedin the analysis
DiscussionThe nationally representative survey indicates that theproportion of outpatients bypassing PHCs increased overthe years in China Urban patients were nearly twice aslikely to bypass PHCs than rural patients This is not un-expected due to the easy access and availability of manySTFs in urban areas Travel distance and travel-relatedcosts are likely to be lower for the urban population [3642] Rural patients often must rely on PHCs in the areadue to the difficulty of accessing alternative health careproviders Especially for rural residents obtaining carefrom upper-level facilities may become quite expensivedue to higher out-of-pocket expenses and longer traveltimes [43]About two in five older adults in China bypassed
PHCs to obtain care from upper-level providers (STFs)
This is despite significantly lower out-of-pocket costs forservices and drugs at PHCs than at the STFs Thereforefinancial incentives have not been adequate to discour-age bypassing of PHCs in China The results imply thatpropensity to bypass PHCs is unlikely to decline signifi-cantly if the financial incentives in favor of PHCs aremade even stronger Given that the bypassing tendencyis related to age ruralurban location present of chronicconditions etc it points to supply-side concerns prob-ably related to availability and quality of service-mix of-fered at the PHCsThe random-effects logistic regression model identi-
fied several factors affecting bypassing of PHCs for ruraland urban residents separately The estimates suggestthat factors affecting the first visits are very similar tofactors affecting all outpatient visits (both new andfollow-up visits) implying that physician recommenda-tions were not important in influencing the choice offacility-types Regardless of rural-urban residence a rela-tive increase in travel time (ratio of travel times to PHCand STF) increased the probability of bypassing PHCsThe result is consistent with the findings in the litera-ture ie increased travel time lowers the utilization ofhealth care facilities [33 44ndash50] Without a formal refer-ral system in urban areas where health resources aremuch richer and STFs are more concentrated than thosein rural areas in China urban patients are more likely tobypass PHCs because of easy accessibility and availabilityof medical care services they needPatients with higher educational attainment show a
higher probability of bypassing PHCs Educational at-tainment is an indicator of socioeconomic status (SES)as well as knowledge about the relative quality of ser-vices facilities offer Middle-aged and older adults withhigher level of income are also more likely to bypassPHCs This probably indicates perception of lower qual-ity of services at the PHCs compared to the STFs Withan increase in income and educational attainment pa-tients become more sensitive to service quality and lesssensitive to cost savings that can be achieved by utilizingPHCsIn rural areas self-reported poor health status in-
creased the likelihood of bypassing PHCs Again thispossibly reflects a lack of confidence in the quality of

services andor non-availability of individualized servicesat the PHC [51 52] Offering individualized services is aperson-centered care approach [53] Patients who expe-rienced hospitalization in the past 12 months are morelikely to bypass PHCs as the hospitalization in the recentpast may be associated with actual or perceived higherseverity of illness or need for individualized services en-couraging utilization of STFs [29] A number of chronicconditions also affect the choice of facility-type Patientswith arthritis or rheumatism were less likely to bypassPHCs probably because these conditions make travelmore difficult [54] especially for rural patients who musttravel significantly longer distances to reach STFsOlder adults show high degree of bypassing PHCs in
urban areas but for rural areas the opposite was true(middle-aged individuals more likely to bypass than theolder adults) This tendency may be associated with lackof relevant services at the PHC level Older adults re-quire more personalized care and continuity of care isimportant for their health status In contrast for ruralareas social value of protecting the health of middle-aged individuals may be higher and travel to a STF ismore costly and difficult for the elderly Among urbanpatients older adults were more likely to bypass PHCsthan those aged 45ndash54 years Geriatric services have notbeen properly incorporated at the primary level in urbanChina [55] which may explain urban older adultsrsquo hesi-tancy to seek care from the PHCs Urban patients withdiabetes are also more likely to use upper-level facilitiesagain reflecting the lack of chronic disease managementat the primary level [56]In urban areas where the upper-level facilities are eas-
ily accessible the tendency to bypass is significantlyhigher With improvements in health status and theaging of the population patients need individualized aswell as continuity of care services Unless those servicesare offered from the PHCs bypassing problem is ex-pected to increase further [57 58]There are several limitations of this study The
CHARLS survey provides information only on the mostrecent outpatient service utilized in the previous 4weeks Measuring the incidence of bypassing using themost recent outpatient visits within the last 4 weeks may
bias the results The survey did not collect informationon facility and provider characteristics and the studycould not analyze the effect of provider characteristicson the choice of health facilities
ConclusionsAbout two in five older adults in China bypassed PHCsto obtain care from upper-level providers (STFs) Urbanpatients were twice as likely as rural patients to bypassPHCs The present study found that relative increase intravel time and more educated had a higher likelihoodof bypassing primary care in rural and urban areasMoreover poor health status and being hospitalized inthe past 12 months had a higher likelihood of bypassingprimary care in rural areas On the other hand arthritisor rheumatism decreased the odds of bypassing Further-more older age and diabetes had a higher likelihood ofbypassing primary care in urban areasContinuity of care and individualized attention require
redesigning the mode of care delivery at the PHC levelwith emphasis on patient-provider trust and adoption ofproactive health promotion and disease prevention Struc-tural changes including the staffing of the PHCs will beneeded to make the PHCs more effective in addressing theneeds of the elderly and middle-aged individuals The find-ings of the study indicate the importance of strengtheningthe service provision in rural PHCs to address commonchronic conditions In fact improving the service deliveryfor addressing the needs of chronic conditions will im-prove utilization of PHCs in both rural and urban areasIn conclusion improving the utilization of PHCs in
China will require improving the quality of services ren-dered from these facilities Perceived quality of medicalcare delivered from the PHCs can be improved if the facil-ities are able to offer comprehensive person-centeredhealth care focusing on the family health care needs andmaking critical screening and preventive services availableAvailability of services alone will not improve overall qual-ity of services ndash it will require a system of continuity ofcare by ensuring good rapport between patients and phy-sicians If patients feel that they have their own primarycare physician in the PHCs the likelihood of seeking carefrom PHCs should be significantly higher

upper-middle income category (OR = 069 p = 0018)Rural patients enrolled in Urban Employee Basic Med-ical Insurance had three times the odds (OR = 301 p lt0001) of bypassing PHCs than the uninsured Comparedwith the uninsured patients urban patients enrolled inNew Rural Cooperative Medical Scheme had a lowerodds of bypassing (OR = 047 p = 0012)Rural patients with poor health were more likely to by-
pass PHCs than those who reported their health beinglsquofairrsquo (OR = 134 p lt 0001) Patients with heart diseasesin rural areas and urban patients with diabetes had ahigher odds of bypassing PHCs (OR = 140 p = 0001OR = 176 p = 0009) and the opposite was true for ruralpatients with arthritis or rheumatism and patients withother major chronic conditions in urban areas (OR =083 p = 0006 OR = 064 p = 0015) Patients who expe-rienced hospitalization in the past 12 months had ahigher odds of bypassing in both the rural and urbanareas (OR = 208 p lt 0001 OR = 215 p lt 0001) Rela-tive travel time was positively associated with patientsbypassing PHCs in rural and urban areas (OR = 115 p lt0001 OR = 128 p lt 0001)Table 3 presents factors affecting bypassing PHCs
when only the first contact outpatient visits are used inthe estimation The results are similar to the estimatesobtained when all visits including the revisits were usedin the analysis
DiscussionThe nationally representative survey indicates that theproportion of outpatients bypassing PHCs increased overthe years in China Urban patients were nearly twice aslikely to bypass PHCs than rural patients This is not un-expected due to the easy access and availability of manySTFs in urban areas Travel distance and travel-relatedcosts are likely to be lower for the urban population [3642] Rural patients often must rely on PHCs in the areadue to the difficulty of accessing alternative health careproviders Especially for rural residents obtaining carefrom upper-level facilities may become quite expensivedue to higher out-of-pocket expenses and longer traveltimes [43]About two in five older adults in China bypassed
PHCs to obtain care from upper-level providers (STFs)
This is despite significantly lower out-of-pocket costs forservices and drugs at PHCs than at the STFs Thereforefinancial incentives have not been adequate to discour-age bypassing of PHCs in China The results imply thatpropensity to bypass PHCs is unlikely to decline signifi-cantly if the financial incentives in favor of PHCs aremade even stronger Given that the bypassing tendencyis related to age ruralurban location present of chronicconditions etc it points to supply-side concerns prob-ably related to availability and quality of service-mix of-fered at the PHCsThe random-effects logistic regression model identi-
fied several factors affecting bypassing of PHCs for ruraland urban residents separately The estimates suggestthat factors affecting the first visits are very similar tofactors affecting all outpatient visits (both new andfollow-up visits) implying that physician recommenda-tions were not important in influencing the choice offacility-types Regardless of rural-urban residence a rela-tive increase in travel time (ratio of travel times to PHCand STF) increased the probability of bypassing PHCsThe result is consistent with the findings in the litera-ture ie increased travel time lowers the utilization ofhealth care facilities [33 44ndash50] Without a formal refer-ral system in urban areas where health resources aremuch richer and STFs are more concentrated than thosein rural areas in China urban patients are more likely tobypass PHCs because of easy accessibility and availabilityof medical care services they needPatients with higher educational attainment show a
higher probability of bypassing PHCs Educational at-tainment is an indicator of socioeconomic status (SES)as well as knowledge about the relative quality of ser-vices facilities offer Middle-aged and older adults withhigher level of income are also more likely to bypassPHCs This probably indicates perception of lower qual-ity of services at the PHCs compared to the STFs Withan increase in income and educational attainment pa-tients become more sensitive to service quality and lesssensitive to cost savings that can be achieved by utilizingPHCsIn rural areas self-reported poor health status in-
creased the likelihood of bypassing PHCs Again thispossibly reflects a lack of confidence in the quality of

services andor non-availability of individualized servicesat the PHC [51 52] Offering individualized services is aperson-centered care approach [53] Patients who expe-rienced hospitalization in the past 12 months are morelikely to bypass PHCs as the hospitalization in the recentpast may be associated with actual or perceived higherseverity of illness or need for individualized services en-couraging utilization of STFs [29] A number of chronicconditions also affect the choice of facility-type Patientswith arthritis or rheumatism were less likely to bypassPHCs probably because these conditions make travelmore difficult [54] especially for rural patients who musttravel significantly longer distances to reach STFsOlder adults show high degree of bypassing PHCs in
urban areas but for rural areas the opposite was true(middle-aged individuals more likely to bypass than theolder adults) This tendency may be associated with lackof relevant services at the PHC level Older adults re-quire more personalized care and continuity of care isimportant for their health status In contrast for ruralareas social value of protecting the health of middle-aged individuals may be higher and travel to a STF ismore costly and difficult for the elderly Among urbanpatients older adults were more likely to bypass PHCsthan those aged 45ndash54 years Geriatric services have notbeen properly incorporated at the primary level in urbanChina [55] which may explain urban older adultsrsquo hesi-tancy to seek care from the PHCs Urban patients withdiabetes are also more likely to use upper-level facilitiesagain reflecting the lack of chronic disease managementat the primary level [56]In urban areas where the upper-level facilities are eas-
ily accessible the tendency to bypass is significantlyhigher With improvements in health status and theaging of the population patients need individualized aswell as continuity of care services Unless those servicesare offered from the PHCs bypassing problem is ex-pected to increase further [57 58]There are several limitations of this study The
CHARLS survey provides information only on the mostrecent outpatient service utilized in the previous 4weeks Measuring the incidence of bypassing using themost recent outpatient visits within the last 4 weeks may
bias the results The survey did not collect informationon facility and provider characteristics and the studycould not analyze the effect of provider characteristicson the choice of health facilities
ConclusionsAbout two in five older adults in China bypassed PHCsto obtain care from upper-level providers (STFs) Urbanpatients were twice as likely as rural patients to bypassPHCs The present study found that relative increase intravel time and more educated had a higher likelihoodof bypassing primary care in rural and urban areasMoreover poor health status and being hospitalized inthe past 12 months had a higher likelihood of bypassingprimary care in rural areas On the other hand arthritisor rheumatism decreased the odds of bypassing Further-more older age and diabetes had a higher likelihood ofbypassing primary care in urban areasContinuity of care and individualized attention require
redesigning the mode of care delivery at the PHC levelwith emphasis on patient-provider trust and adoption ofproactive health promotion and disease prevention Struc-tural changes including the staffing of the PHCs will beneeded to make the PHCs more effective in addressing theneeds of the elderly and middle-aged individuals The find-ings of the study indicate the importance of strengtheningthe service provision in rural PHCs to address commonchronic conditions In fact improving the service deliveryfor addressing the needs of chronic conditions will im-prove utilization of PHCs in both rural and urban areasIn conclusion improving the utilization of PHCs in
China will require improving the quality of services ren-dered from these facilities Perceived quality of medicalcare delivered from the PHCs can be improved if the facil-ities are able to offer comprehensive person-centeredhealth care focusing on the family health care needs andmaking critical screening and preventive services availableAvailability of services alone will not improve overall qual-ity of services ndash it will require a system of continuity ofcare by ensuring good rapport between patients and phy-sicians If patients feel that they have their own primarycare physician in the PHCs the likelihood of seeking carefrom PHCs should be significantly higher

upper-middle income category (OR = 069 p = 0018)Rural patients enrolled in Urban Employee Basic Med-ical Insurance had three times the odds (OR = 301 p lt0001) of bypassing PHCs than the uninsured Comparedwith the uninsured patients urban patients enrolled inNew Rural Cooperative Medical Scheme had a lowerodds of bypassing (OR = 047 p = 0012)Rural patients with poor health were more likely to by-
pass PHCs than those who reported their health beinglsquofairrsquo (OR = 134 p lt 0001) Patients with heart diseasesin rural areas and urban patients with diabetes had ahigher odds of bypassing PHCs (OR = 140 p = 0001OR = 176 p = 0009) and the opposite was true for ruralpatients with arthritis or rheumatism and patients withother major chronic conditions in urban areas (OR =083 p = 0006 OR = 064 p = 0015) Patients who expe-rienced hospitalization in the past 12 months had ahigher odds of bypassing in both the rural and urbanareas (OR = 208 p lt 0001 OR = 215 p lt 0001) Rela-tive travel time was positively associated with patientsbypassing PHCs in rural and urban areas (OR = 115 p lt0001 OR = 128 p lt 0001)Table 3 presents factors affecting bypassing PHCs
when only the first contact outpatient visits are used inthe estimation The results are similar to the estimatesobtained when all visits including the revisits were usedin the analysis
DiscussionThe nationally representative survey indicates that theproportion of outpatients bypassing PHCs increased overthe years in China Urban patients were nearly twice aslikely to bypass PHCs than rural patients This is not un-expected due to the easy access and availability of manySTFs in urban areas Travel distance and travel-relatedcosts are likely to be lower for the urban population [3642] Rural patients often must rely on PHCs in the areadue to the difficulty of accessing alternative health careproviders Especially for rural residents obtaining carefrom upper-level facilities may become quite expensivedue to higher out-of-pocket expenses and longer traveltimes [43]About two in five older adults in China bypassed
PHCs to obtain care from upper-level providers (STFs)
This is despite significantly lower out-of-pocket costs forservices and drugs at PHCs than at the STFs Thereforefinancial incentives have not been adequate to discour-age bypassing of PHCs in China The results imply thatpropensity to bypass PHCs is unlikely to decline signifi-cantly if the financial incentives in favor of PHCs aremade even stronger Given that the bypassing tendencyis related to age ruralurban location present of chronicconditions etc it points to supply-side concerns prob-ably related to availability and quality of service-mix of-fered at the PHCsThe random-effects logistic regression model identi-
fied several factors affecting bypassing of PHCs for ruraland urban residents separately The estimates suggestthat factors affecting the first visits are very similar tofactors affecting all outpatient visits (both new andfollow-up visits) implying that physician recommenda-tions were not important in influencing the choice offacility-types Regardless of rural-urban residence a rela-tive increase in travel time (ratio of travel times to PHCand STF) increased the probability of bypassing PHCsThe result is consistent with the findings in the litera-ture ie increased travel time lowers the utilization ofhealth care facilities [33 44ndash50] Without a formal refer-ral system in urban areas where health resources aremuch richer and STFs are more concentrated than thosein rural areas in China urban patients are more likely tobypass PHCs because of easy accessibility and availabilityof medical care services they needPatients with higher educational attainment show a
higher probability of bypassing PHCs Educational at-tainment is an indicator of socioeconomic status (SES)as well as knowledge about the relative quality of ser-vices facilities offer Middle-aged and older adults withhigher level of income are also more likely to bypassPHCs This probably indicates perception of lower qual-ity of services at the PHCs compared to the STFs Withan increase in income and educational attainment pa-tients become more sensitive to service quality and lesssensitive to cost savings that can be achieved by utilizingPHCsIn rural areas self-reported poor health status in-
creased the likelihood of bypassing PHCs Again thispossibly reflects a lack of confidence in the quality of

services andor non-availability of individualized servicesat the PHC [51 52] Offering individualized services is aperson-centered care approach [53] Patients who expe-rienced hospitalization in the past 12 months are morelikely to bypass PHCs as the hospitalization in the recentpast may be associated with actual or perceived higherseverity of illness or need for individualized services en-couraging utilization of STFs [29] A number of chronicconditions also affect the choice of facility-type Patientswith arthritis or rheumatism were less likely to bypassPHCs probably because these conditions make travelmore difficult [54] especially for rural patients who musttravel significantly longer distances to reach STFsOlder adults show high degree of bypassing PHCs in
urban areas but for rural areas the opposite was true(middle-aged individuals more likely to bypass than theolder adults) This tendency may be associated with lackof relevant services at the PHC level Older adults re-quire more personalized care and continuity of care isimportant for their health status In contrast for ruralareas social value of protecting the health of middle-aged individuals may be higher and travel to a STF ismore costly and difficult for the elderly Among urbanpatients older adults were more likely to bypass PHCsthan those aged 45ndash54 years Geriatric services have notbeen properly incorporated at the primary level in urbanChina [55] which may explain urban older adultsrsquo hesi-tancy to seek care from the PHCs Urban patients withdiabetes are also more likely to use upper-level facilitiesagain reflecting the lack of chronic disease managementat the primary level [56]In urban areas where the upper-level facilities are eas-
ily accessible the tendency to bypass is significantlyhigher With improvements in health status and theaging of the population patients need individualized aswell as continuity of care services Unless those servicesare offered from the PHCs bypassing problem is ex-pected to increase further [57 58]There are several limitations of this study The
CHARLS survey provides information only on the mostrecent outpatient service utilized in the previous 4weeks Measuring the incidence of bypassing using themost recent outpatient visits within the last 4 weeks may
bias the results The survey did not collect informationon facility and provider characteristics and the studycould not analyze the effect of provider characteristicson the choice of health facilities
ConclusionsAbout two in five older adults in China bypassed PHCsto obtain care from upper-level providers (STFs) Urbanpatients were twice as likely as rural patients to bypassPHCs The present study found that relative increase intravel time and more educated had a higher likelihoodof bypassing primary care in rural and urban areasMoreover poor health status and being hospitalized inthe past 12 months had a higher likelihood of bypassingprimary care in rural areas On the other hand arthritisor rheumatism decreased the odds of bypassing Further-more older age and diabetes had a higher likelihood ofbypassing primary care in urban areasContinuity of care and individualized attention require
redesigning the mode of care delivery at the PHC levelwith emphasis on patient-provider trust and adoption ofproactive health promotion and disease prevention Struc-tural changes including the staffing of the PHCs will beneeded to make the PHCs more effective in addressing theneeds of the elderly and middle-aged individuals The find-ings of the study indicate the importance of strengtheningthe service provision in rural PHCs to address commonchronic conditions In fact improving the service deliveryfor addressing the needs of chronic conditions will im-prove utilization of PHCs in both rural and urban areasIn conclusion improving the utilization of PHCs in
China will require improving the quality of services ren-dered from these facilities Perceived quality of medicalcare delivered from the PHCs can be improved if the facil-ities are able to offer comprehensive person-centeredhealth care focusing on the family health care needs andmaking critical screening and preventive services availableAvailability of services alone will not improve overall qual-ity of services ndash it will require a system of continuity ofcare by ensuring good rapport between patients and phy-sicians If patients feel that they have their own primarycare physician in the PHCs the likelihood of seeking carefrom PHCs should be significantly higher

services andor non-availability of individualized servicesat the PHC [51 52] Offering individualized services is aperson-centered care approach [53] Patients who expe-rienced hospitalization in the past 12 months are morelikely to bypass PHCs as the hospitalization in the recentpast may be associated with actual or perceived higherseverity of illness or need for individualized services en-couraging utilization of STFs [29] A number of chronicconditions also affect the choice of facility-type Patientswith arthritis or rheumatism were less likely to bypassPHCs probably because these conditions make travelmore difficult [54] especially for rural patients who musttravel significantly longer distances to reach STFsOlder adults show high degree of bypassing PHCs in
urban areas but for rural areas the opposite was true(middle-aged individuals more likely to bypass than theolder adults) This tendency may be associated with lackof relevant services at the PHC level Older adults re-quire more personalized care and continuity of care isimportant for their health status In contrast for ruralareas social value of protecting the health of middle-aged individuals may be higher and travel to a STF ismore costly and difficult for the elderly Among urbanpatients older adults were more likely to bypass PHCsthan those aged 45ndash54 years Geriatric services have notbeen properly incorporated at the primary level in urbanChina [55] which may explain urban older adultsrsquo hesi-tancy to seek care from the PHCs Urban patients withdiabetes are also more likely to use upper-level facilitiesagain reflecting the lack of chronic disease managementat the primary level [56]In urban areas where the upper-level facilities are eas-
ily accessible the tendency to bypass is significantlyhigher With improvements in health status and theaging of the population patients need individualized aswell as continuity of care services Unless those servicesare offered from the PHCs bypassing problem is ex-pected to increase further [57 58]There are several limitations of this study The
CHARLS survey provides information only on the mostrecent outpatient service utilized in the previous 4weeks Measuring the incidence of bypassing using themost recent outpatient visits within the last 4 weeks may
bias the results The survey did not collect informationon facility and provider characteristics and the studycould not analyze the effect of provider characteristicson the choice of health facilities
ConclusionsAbout two in five older adults in China bypassed PHCsto obtain care from upper-level providers (STFs) Urbanpatients were twice as likely as rural patients to bypassPHCs The present study found that relative increase intravel time and more educated had a higher likelihoodof bypassing primary care in rural and urban areasMoreover poor health status and being hospitalized inthe past 12 months had a higher likelihood of bypassingprimary care in rural areas On the other hand arthritisor rheumatism decreased the odds of bypassing Further-more older age and diabetes had a higher likelihood ofbypassing primary care in urban areasContinuity of care and individualized attention require
redesigning the mode of care delivery at the PHC levelwith emphasis on patient-provider trust and adoption ofproactive health promotion and disease prevention Struc-tural changes including the staffing of the PHCs will beneeded to make the PHCs more effective in addressing theneeds of the elderly and middle-aged individuals The find-ings of the study indicate the importance of strengtheningthe service provision in rural PHCs to address commonchronic conditions In fact improving the service deliveryfor addressing the needs of chronic conditions will im-prove utilization of PHCs in both rural and urban areasIn conclusion improving the utilization of PHCs in
China will require improving the quality of services ren-dered from these facilities Perceived quality of medicalcare delivered from the PHCs can be improved if the facil-ities are able to offer comprehensive person-centeredhealth care focusing on the family health care needs andmaking critical screening and preventive services availableAvailability of services alone will not improve overall qual-ity of services ndash it will require a system of continuity ofcare by ensuring good rapport between patients and phy-sicians If patients feel that they have their own primarycare physician in the PHCs the likelihood of seeking carefrom PHCs should be significantly higher

services andor non-availability of individualized servicesat the PHC [51 52] Offering individualized services is aperson-centered care approach [53] Patients who expe-rienced hospitalization in the past 12 months are morelikely to bypass PHCs as the hospitalization in the recentpast may be associated with actual or perceived higherseverity of illness or need for individualized services en-couraging utilization of STFs [29] A number of chronicconditions also affect the choice of facility-type Patientswith arthritis or rheumatism were less likely to bypassPHCs probably because these conditions make travelmore difficult [54] especially for rural patients who musttravel significantly longer distances to reach STFsOlder adults show high degree of bypassing PHCs in
urban areas but for rural areas the opposite was true(middle-aged individuals more likely to bypass than theolder adults) This tendency may be associated with lackof relevant services at the PHC level Older adults re-quire more personalized care and continuity of care isimportant for their health status In contrast for ruralareas social value of protecting the health of middle-aged individuals may be higher and travel to a STF ismore costly and difficult for the elderly Among urbanpatients older adults were more likely to bypass PHCsthan those aged 45ndash54 years Geriatric services have notbeen properly incorporated at the primary level in urbanChina [55] which may explain urban older adultsrsquo hesi-tancy to seek care from the PHCs Urban patients withdiabetes are also more likely to use upper-level facilitiesagain reflecting the lack of chronic disease managementat the primary level [56]In urban areas where the upper-level facilities are eas-
ily accessible the tendency to bypass is significantlyhigher With improvements in health status and theaging of the population patients need individualized aswell as continuity of care services Unless those servicesare offered from the PHCs bypassing problem is ex-pected to increase further [57 58]There are several limitations of this study The
CHARLS survey provides information only on the mostrecent outpatient service utilized in the previous 4weeks Measuring the incidence of bypassing using themost recent outpatient visits within the last 4 weeks may
bias the results The survey did not collect informationon facility and provider characteristics and the studycould not analyze the effect of provider characteristicson the choice of health facilities
ConclusionsAbout two in five older adults in China bypassed PHCsto obtain care from upper-level providers (STFs) Urbanpatients were twice as likely as rural patients to bypassPHCs The present study found that relative increase intravel time and more educated had a higher likelihoodof bypassing primary care in rural and urban areasMoreover poor health status and being hospitalized inthe past 12 months had a higher likelihood of bypassingprimary care in rural areas On the other hand arthritisor rheumatism decreased the odds of bypassing Further-more older age and diabetes had a higher likelihood ofbypassing primary care in urban areasContinuity of care and individualized attention require
redesigning the mode of care delivery at the PHC levelwith emphasis on patient-provider trust and adoption ofproactive health promotion and disease prevention Struc-tural changes including the staffing of the PHCs will beneeded to make the PHCs more effective in addressing theneeds of the elderly and middle-aged individuals The find-ings of the study indicate the importance of strengtheningthe service provision in rural PHCs to address commonchronic conditions In fact improving the service deliveryfor addressing the needs of chronic conditions will im-prove utilization of PHCs in both rural and urban areasIn conclusion improving the utilization of PHCs in
China will require improving the quality of services ren-dered from these facilities Perceived quality of medicalcare delivered from the PHCs can be improved if the facil-ities are able to offer comprehensive person-centeredhealth care focusing on the family health care needs andmaking critical screening and preventive services availableAvailability of services alone will not improve overall qual-ity of services ndash it will require a system of continuity ofcare by ensuring good rapport between patients and phy-sicians If patients feel that they have their own primarycare physician in the PHCs the likelihood of seeking carefrom PHCs should be significantly higher
