Abstract
The costs of pediatric telemedicine services remain underreportedand understudied; however, there is evidence that telepediatric ser-
vices can be cost competitive with traditional ones. For 15 years, the
University of Kansas Center for Telemedicine and Telehealth has
been providing telemental health outreach from the University of
Kansas Medical Center (KUMC). One service site is located in
Crawford County, Kansas, which provides telepsychiatry services to
children and adolescents. The purpose of this study was to examine
the costs of operating the Crawford County site relative to accessing
services at KUMC, the likely alternative service location. The cost of
travel time to parents who accompanied a dependent to either lo-
cation also was estimated. Patients and parents were examined over
a 6-month period in 2006. One hundred thirty-two patients received
257 telemedicine psychiatric consultations during this period. Costestimates for using the pediatric telemedicine service were assessed
for all patients; however, travel and related costs were collected from
a sample of 26 patientparent dyads. The estimated costs of services
were obtained using standard cost-accounting procedures. An av-
erage cost per consultation in Crawford County was $168.61. The
cost savings in travel time and other expenses to parents and patients
were substantial between use of the county site and KUMC. Sub-
tracting average savings in travel costs to patients and parents
produced an average cost of a telepsychiatry consult in Crawford
County of only $30.99. This study was conducted over 6 months with
a small number of observations; it should be replicated over a longer
study period, with more patients, and with more data that might
capture marginal costs of services.

Introduction and Literature Review
The University of Kansas Center for Telemedicine and Tele-
health at the University of Kansas Medical Center (KUMC)
has been providing telemental health services for 15 years
in Kansas. For*12 of these years, a robust telepsychiatry
clinic has been operating at a community mental health center lo-
cated in Crawford County in the southeast region of Kansas. In co-
operation with the community mental health center administrators
and the attending telepsychiatrist, a cost-accounting analysis was
completed to better understand the institutional and patient costs
associated with providing telepsychiatry in rural Kansas.
A PubMed search of articles and reports was conducted on
September11, 2009, forthe years 2000 to present using thefollowing
search terms: telemedicinepsychiatry (379); telemedicinepsy-
chiatrypediatrics (14); and telemedicinepsychiatry cost (5).
The number of articles or reports found is shown in parentheses. Of
the five articles found that deal with the topic of this analysis, only
twocontained empiricalcost data. Theotherthreewere reviews of the
literature.
Hersh et al.1 reviewed the literature in telemedicine used for
Medicare before 2000, of which our interest in pediatric tele-
psychiatry would only be a small subset. In any case, the Hersh et al.1
review identified only 28 studies; none of these dealt with pediatric
service cost, the topic of this study. The authors conclusions were
that, studies assessing the efficacy or cost are insufficient to permit
definitive statements about the evidence supporting (or not sup-
porting) the benefits of telemedicine. Pesamaa et al.2 searched for
articles covering the period of 1966 to June 2003 for videoconfer-
encing in child and adolescent telepsychiatry, and found 27 articles
covering patient care or consultation, evaluation of a clinical service
or education, and assessments of satisfaction with videoconferenc-
ing. Three studies presented some calculations of cost-effectiveness;
however, costs were very crudely measured, and procedures used
were not reported in sufficient detail to determine exactly how or
which costs were measured. A more recent review of clinical tele-
health across the disciplines by Jarvis-Selinger et al.3 identified 397
articles focused on videoconferencing in clinical contexts, but this
included a wide array of medical disciplines both adult and pediatric.
Those studies providing explicit cost estimates were not identified by
the authors, but they stated, because fixed costs of establishing
telemedicine programs are substantial a sufficient amount of work-load is required to justify equipmentexpenditures. They did notnote
that these costs have fallen sharply over the last decade, and the data
supporting their assertion are not provided.
The two cost studies found in the current search were quite dif-
ferent. Edwards and Patel4 provided an important description of a
telemedicine program designed to meet needs of a remote rural
population in Maine. Forty-one percent of the clinical consultations
(n518) were provided to mental health/psychiatry patients, but the
number of services provided to children versus adults is not given.

The costs reported were those saved by staff engaged in distant
clinical, educational, and administrative activities versus provider
and participant on-site delivery of services. The reported savings are
substantial from $386 to $491 perconsultation. The costs reported by
Edwards and Patel4 have little relevance to this article, which is fo-
cused on the delivery of distant psychiatric consultations to childrenand adolescents.
The article by Smith et al.5 comes closest to addressing our con-
cerns. They examined the costs of providing 1,499 clinical consul-
tations to patients over 5 years through a telepediatric service in
Queensland, Australia. Only 2% of consultations were telepsychiatry
services. They found average telemedicine costs per consultation to
be A$637.76 (about U.S. $551.08) versus average face-to-face or
traditional service costs of A$1,036.20 (about U.S. $895.38). The
authors conducted a break-even analysis to find that costs of tele-
medicine services reach a threshold of cost equality with traditional
services when 774 telemedicine consultations are provided. Con-
sultations beyond774 would provide a cost advantageto the distance
modality. Unfortunately, linear break-even analysis can be mis-
leading when cost-curves are declining sharply and nonlinearly as
commonly observed in telemedicine services.
Doolittle et al.6 were able to estimate pseudo-cost-curves for 386
telemedicine consultations provided to children in 10 school clinics,
including total, average, and marginal costs of the service. This
analysis indicated that a cost savings in favor of telemedicine oc-
curred when 165200 consultations were provided annually at a
service site. About 23% of the consultations provided in the study
were psychiatric and the rest were ambulatory pediatric consultations
of various types. The average cost of a consultation at a point of
equality between telemedicine and traditional face-to-face consul-
tation was about $153. The University of Kansas Center for Tele-medicine and Telehealth was the telemedicine service provider.
While there appears to be a substantial discrepancy between these
estimates and the Australian study, these may arise due to the use of
cost-curves versus break-even analysis, where the later would
overestimate costs that had a sharply declining marginal cost-curve
as illustrated in Doolittle et al.6 Additionally, the consultations pro-
vided at KUMC were predominantly well-child and preventive care
that may be less costly than the variety of specialty services required
by and provided to children in the Australian study. Last, it is highly
likely that fixed and variable costs were accounted for differently in
the two studies. Telepsychiatry for children and adolescents is only
one of a number of services provided at KUMC using dedicated
equipment and staff; therefore, overhead costs were apportioned bypercentage usage among the services provided to children in school
and other uses of the KUMC telemedicine facility. At >165 consults
the KUMC and school-clinic-site fixed costs become relatively small
and total costs approach variable costs. After adjusting the average
Australian variable cost in U.S. dollars per consultation by various
deflators to 2002 U.S. dollars, the adjusted Australian average vari-
able costs to be about $170, which is quite close to our estimate of
$153 at the U.S. threshold. This lends some concurrent validity to the
results of both studies.
In previous studies, we have shown that travel time and costs of
providers to distant service sites are not cost competitive with tele-
medicine.7,8 This finding is consistent with Edwards and Patel4
however, our previous cost studies were in adult teleoncology. The
purpose of this article is to report some findings concerning costs of
providing telepsychiatry services to children and adolescents. Anoted above, costs of telemedicine remain underreported and the
provision of pediatric services is particularly understudied, but there
is some evidence that telepediatric consultations can be more than
cost competitive with traditional ones.
The data accumulated in this study permit cost reporting of the
telepsychiatry service relevant to the providers, KUMC, and the dis
tant site in a rural Kansas county. Included are estimated average
costs of service provision by the providers and savings in travel costs
to patients and families as they utilize telemedicine for the psychi-
atric care of children.
Service SettingFrom January 1, 2006, through June 30, 2006, all psychiatric
consultations provided to child (up to 12 years) and adolescent (1318
years) patients through a telemedicine modality in Crawford County
Kansas, were monitored for later calculations of the cost of the ser-
vice to both providers and to patients. Two hundred fifty-seven tele
medicine psychiatric consultations were provided to 132 uniqu
patients during this 6-month observation period. Personnel changes a
both the service and KUMC sites delayed these data from earlie
publication. Although some time has passed, these data suggest cos
savings that may be even more significant in current dollars.
The Crawford County service site was *136 miles from KUMC o
*2 h and 19 min average one-way travel time. Crawford County in
the southeast corner of Kansas has a population of 38,242, 93%white, 23% under 18 years of age, and 17% of youth live below the
poverty line. Pittsburg is the largest town in the county with a pop-
ulation of 19,152. KUMC-affiliated providers, county govern
ment, and private practitioners are the sources of primary medica
care for the populace. There is only one pediatric psychiatrist in the
county.
MethodsInstitutional Review Board approval was obtained for this study
due to the involvement of human subjects, particularly children
under the age of 18, and all participants provided signed consent. Fo
analysis,two types of cost data were collected. Thefirst were thecost
of operating the two service sites. The second was the cost of travetime of the accompanying parent or parents in cases in which more
than one parent accompanied the child or adolescent.
The estimated costs of services provided are comprehensive. Al
costs, including overheads arising from the treatment of these pa-
tients at the service site in Crawford County and at the originating
telemedicine site at KUMC, are calculated using common hospi
tal accounting procedures to measure fixed and variable costs.
Applications of these procedures in this study are briefly mentioned
below.

COSTS TO PROVIDERS
All telemedicine services were provided by psychiatrists at KUMC.
This service was provided under contract with the patient service site.
All related minor administrative needs and costs, such as record-
keeping for the teleconsultations, were covered by the KUMC phy-
sician contract. Despite this, the contracted physician costs may
underestimate actual physician time costs, since the negotiated
contract was priced attractively for the service site and was estimated
to be close to the Medicaid reimbursed cost. Thus, the degree of
underestimation in the contract would be similar to underpayments
by Medicaid for this service. Nevertheless, this cost roughly ap-
proximated the actual variable costs of physician services.
The one pediatric psychiatrist regularly practicing on-site in
Crawford County was not a member of the KUMC faculty, and he
rendered face-to-face services to patients throughout this observa-
tion period but not to patients receiving telemedicine consultations.
Costs related to this on-site physician are not included in the service
costs of this report. In our results, these physician contracted ex-
penses are recorded under Crawford County costs.
All other personnel expenses were directly paid by the Crawford
County site. These included a nurse practitioner, a registered nurse or
licensed practical nurse, and clerical time. The costs reported below
were calculated on a percentage use of time by pediatric tele-
psychiatry patients. Equipment costs were fully amortized annual
expenses of all telemedicine equipment.
The only operating expenses or variable costs recorded at the
KUMC site were annual line charges and the use of technical/main-
tenance support. Equipment at KUMC was fully amortized; therefore,
we adjusted the estimate of annual charges to be equal to those
charged under Crawford County costs. Technical/maintenance sup-
port was much lower than would be encountered during a start-up orearly operation, since the delivery of other telemedicine services had
led to the training of on-site personnel in trouble shooting. Required
trouble-shooting operations beyond the expertise of these personnel
were conveniently handled by telephone with a technician at KUMC
during the 6-month observation period.
Fixed costs were allocated as follows. The cost of office space for
service delivery was theprice per square foot forsimilar officespace in
Pittsburg and Kansas City, Kansas, multiplied by the actual percentage
of square footage utilized for service delivery. Prices were obtained
from real estate data searches in the two communities utilizing both
Web searches and inquiries with real estate agents. The price used per
square foot was almost 50% higher in Kansas City, Kansas, at $17 per
square foot versus $12 per square foot in Pittsburg, Kansas. Despitethis lower cost persquare foot in Pittsburg,the total facilityspace used
for the consultations was much larger than the Kansas City space,
resulting in a much higher office space cost. Space utilized was al-
located on a percentage of space available that was used for service to
telepsychiatry patients. This percent allocated space amounted to
slightly>337 sq. ft. in Crawford County and 22 sq. ft. at KUMC.
Administrative costs were allocated to the Crawford County site
based on the percentage of pediatric telepsychiatry services of the
total of all patient services delivered at the site during the 6-month
period. Medical records costs and insurance costs were similarly al-
located. Although some might consider utility costs a variable cost,
these are considered under administrative costs, since the percentage
of actual utility expenses consumed by the service under observation
was minimal and not easily separated from other administrative
expenses at the service site.Average costs of a consultation to providers (Crawford and KUMC)
separately and combined are reported below. The results were care-
fully reviewed by the health economist on the study team.
TRAVEL COSTS SAVINGS TO PATIENTS
Data permitting cost estimates to be made for accessing the pe-
diatric telemedicine service by patients were obtained prospectively
from 26 unique patientadult dyads, almost a 20% sampling of
patients actually served. These 26 dyads were chosen because they
provided the most complete records of information for these sim-
ulations. The data obtained provided calculations of travel distances
and time by patients to the Crawford County service site and KUMC
as an alternative site. Mode of transportation was uniformly by
private car, and all but three of the patients were accompanied by
an adult. No cost of travel time was estimated for the patient, but
those with accompanying adults had estimated travel-time costs
that were obtained by multiplying estimated round-trip travel times
by the hourly wage rate for the self-identified occupations of the
accompanying adults. These wage rates were obtained from the
Bureau of Labor Statistics, U.S. Department of Labor, using 2006
reported Kansas nonmetropolitan wage estimates for employment
classifications.10Although annual salary data were gathered for this
study, a poor response rate on this item prevented an accurate
travel cost calculation. In a pilot study of the use of our data col-
lection form in this setting, parents refused to answer an incomequestion even though this form used salary ranges not actual in-
comes. It is not known why respondents were reluctant to answer
this question, except to suggest that income level remains a sen-
sitive issue.
Accurate data relating to the time spent by patients receiving the
actual consultations or by the accompanying adult were also not
available, so this information is not included in these estimates.
Monte Carlo resamplings are reported below using information from
the 26 patients, probability distributions of the number of accom-
panying parents, travel-times, wage rates, and the additional 231
observations included in the study database.
The reported travel costs are average savings in the difference in
travel time between the local site and KUMC, plus $0.35/mile forround-trip automobile travel expenses using the distance saved by
travel to the local site. We believe that these costs and mileages
are suitably conservative estimates of real travel costs at the time
of this study. The three patients who drove themselves to the service
site are included in the calculation of average distance travel cost
savings.
Our survey responses from these 26 dyads indicated no other large
potential patient cost savings to accessing the telepsychiatry service
than travel-related ones. Therefore, our report is solely one of travel

cost savings arising from local access to patients versus a trip to
KUMC.
MONTE CARLO RESAMPLINGS OF TRAVEL DISTANCES,
TIMES, AND COSTS
The costs in Table 1 were generated using 150,000 Monte Carlo
resamplings of the driving distances and times for the 257 observa-
tions provided through telepsychiatry. Empirical distributions of
actual patient driving distances to the local Clinic and KUMC were
calculated using averages of Mapquest and Google Map to insure
accurate times and distances. These times and distances were based
on the 257 patient, local clinic, and KUMC addresses. Using these
actual distributions of distances and times, 5,000 resamplings and 30
replications yielded the means and standard deviations of times,
distances, and costs reported in Table 1.
11
Resamplings used threerandom numbers to define the distances and times to the Crawford
clinic site and KUMC as well as whether there were, in addition to the
patient, 0, 1, or 2 accompanying adults in the vehicle.
ResultsTRAVEL COSTS SAVINGS TO PATIENTS
Table 1 reports the means and standard deviation for local travel
costs, KUMC travel time costs, differences between local and KUMC
travel time costs, the vehicle mileage cost differentials to KUMC, and
the total cost differential of KUMC versus using the local pediatric
telepsychiatry site.
COSTS TO PROVIDERSTable 2 below reports study results relative to the costs of services
provided through the Crawford County site and KUMC. The average
or mean per consult cost of this telemedicine service is $168.61. This
estimated cost does not include any research costs or start-up costs.
It might be seen as an average cost of clinicalserviceas a goingconcern.
These data suggest substantial average or mean cost savings to the
patients and families of $137.62 per consult. If this figure is multi-
plied over the 257 study consults, it suggests that the average savings
to patients of this service over 6 months was $35,369.

COMPARISON OF PROVIDER COSTS AND PATIENT
SAVINGS IN TRAVEL COSTS
The savings in patient travel costs substantially offset the provider
costs of the service. The provider cost is only $7,964 in excess of
patient savings (i.e., $43,333$35,369); therefore, the net average cost
of a consult after subtracting patient travel costs savings is $30.99 (i.e.,
$7,964/257). This figure does not include many other potential cost
savings to the patient and the service sites, nor does this cost ac-
counting figure account for the additional service rendered to the
community through the availability of thetelemedicine service andthe
freeing of time of the one resident psychiatrist to serve other patients.
Discussion and ConclusionsOne must not lose sight of the fact that providers of a service and
patients are different entities. Provider institutions must meet their
total financial requirements, whereas patients would prefer to min-
imize their costs and even shift cost burdens to someone else. For
these reasons, careful attention must be paid to how service costs areactually allocated in an economy. The situation examined in this
report seems to suggest benefits from telepsychiatry to both providers
and patients.
It should be noted that the costs of the on-site pediatric psychia-
trist were not factored into this study for comparison purposes. U.S.
Department of Labor Statistics from 2006 indicate that the average
hourly wage of a psychiatrist was $70.97, not including benefits,
insurance, licensing, or other expenses. At an average cost of U.S.
$168.61 per consultation, the telepsychiatry service appears similar
to earlier estimated costs reported by Doolittle et al.6 and other
studies of telemedicine services. This cost per consultation is clearly
more than cost-competitive compared to the cost of a psychiatrist
who physically travels to this site. Given the limited availability ofchild psychiatrists in rural areas, the costs identified are likely to be
acceptable for centers that are unable to recruit a resident psychia-
trist. Given the context of this study, the arrangement described
appears to be financially and operationally beneficial to the com-
munity mental health center, even with an existing staff psychiatrist
in the community.
While the telepsychiatry service studied here is relatively isolated
and occurs at a single site, there is no reason to believe that similar
cost figures could not be observed for other telepsychiatry practices
in rural areas. Practices that employ similar videoconference
equipment and Internet protocol connectivity would share compa-
rable technical costs, and many of the clinical and administrative
expenses would be similar. The physician cost is likely the mostvariable expense, depending on the negotiated components of the
contract. Nonetheless, this study can serve as a guide forthe financial
considerations of a rural telepsychiatry practice, as well as a method
for conducting a cost-accounting analysis of the program.
This was a limited study conducted over 6 months with a small
number of observations. A longer study period with more unique
patients and observations is suggested to refine the cost model. A
comparison with on-site psychiatry expenses would also be valuable
in helping rural centers determine the best service choice for psy-
chiatry.
