UNDERSTANDING DIMENSIONALITY IN HEALTH CARE
Abstract
In recent years, the quality of non-clinical elements of health care has beenchallenged in the UK. While elements such as communications, empathy,
environment etc. all contribute hugely to care of patients, they often fall short of what
they should be. This paper considers how these are currently evaluated
operationally before a review of extant literature on dimensionality in services
generally. It goes on to describe the methodology behind the exploratory phase of a
larger project to generate a greater understanding of the dimensionality of health
care with the ultimate aim of devising an evaluation model designed specifically for
the health sector.
Key words: quality, health, service, SERVQUAL, dimensionality
1. Aim and Objectives
Aim
To understand the dimensionality of quality in health services
Objectives
I. Review existing means of evaluating the quality of non-clinical elements of
care in health services
II. Critique the SERVQUAL model with particular reference to health services
III. Identify what dimensions are important to service users.
2. Introduction
The service sector is an important part of the UK economy with a workforce of
25.76m out of a total UK workforce of 31.26m. Of this the public sector represents
21% of the overall UK workforce (Office for National Statistics, 2011). Economically,
the NHS alone accounts for a budget of 114bn (Department of Health, 2010).
With one million people accessing health services every 36 hours (Triggle, 2012),
health services is a major contributor to both social and economic influences, yet
despite ongoing debate, service quality in this sector remains an enigmatic elementand has attracted little academic progression in its measurement since the
development of SERVQUAL 25 years ago.

3. Review of the Evaluation of Health Care
Health care organisations are facing pressures from a variety of directions, one of
which is the introduction of competition in the sector. This new phenomenon is
pushing hospitals and community services to take a hard look at the quality of the
services they offer as they face increasing demands to meet or exceed patient
expectations (Dougall et al., 1999). This is a difficult aspiration, especially in an
environment where some elements of patient dissatisfaction may be out of their
control (Vukmir, 2006), such as the needs of different demographic groups, the
involvement of partner agencies, government intervention, etc.
The quality of health care remains a problem (Gummesson, 2001) and in the UK,
where the National Health Service (NHS) has an almost monopolistic place in the
sector, the challenges it faces are many and varied and have been categorised as:
(O'Connor et al., 1988)
i. Service elusiveness the nature of health care often means that the patient
does not know what to expect; it is difficult for them to assimilate what the service
means (Berry et al., 1988).
ii. Employee diversity health care is dependent on a huge diversity of
employees with different skills and personalities who have to work together (Bellou,
2007). Each plays a crucial role contributing to the patients perception of quality.
iii. Interrelatedness patients require education to help them to understand the
service and thus help them in their evaluation (O'Connor et al., 1988).
The complexities of delivering health care means that its evaluation is challenging
with a lack of resources, resistance by staff to data collection and inexperience andpoor training for managers and staff (Eiriz & Figueiredo, 2005). Often those who are
delegated the responsibility of managing quality are given the role as an add on to
their main job (Desombre & Eccles, 1998).
While numerous attempts are made to measure quality in health care, they are
often complex in nature, are usually national and based on political issues such as
targets rather than elements of care based on qualitative work with patients
(Goodrich & Cornwell, 2008). The NHS has been said to be awash with data but
short on information (Dr. Foster, 2009). It measures performance rather than
quality.
Of the plethora of measures used to monitor health care, the four key ones are
through Dr. Foster, Care Quality Commission (CQC), National Patient Survey and
Quality and Outcomes Framework (QOF). None of these have strong local
ownership or are designed with local priorities in mind.

2.1 Dr Foster
Dr Foster is an independent organisation which provides comparative records for
every hospital in the country, on-line tools for the public to complete and records
data in consumer guides allowing prospective patients to make informed decisions
on which hospital they wish to attend. Data is used to benchmark trusts against
national trends in quality, safety and efficiency.
An on-line tool allows the public to prioritise six pre-selected elements that areimportant to them by use of a Likert scale.
Cleanliness
Comfort
Right information, participation in decisions, confident and in control
Timely and well co-ordinated care
Respect and honesty
Treated with compassion
2.2. Care Quality Commission
This Commission monitors care offered by all health care providers to ensure they
meet government standards of quality and safety.
The Care Quality Commission (CQC) offers integrated regulation for health and
social care in England. Its aim is to ensure better care for everyone in hospital, in a
care home and at home. (Care Quality Commission, 2011a).
All NHS trusts are required to register with the CQC, which in turn monitors their
performance through annual self completion assessments, visits, surveys, MPs, local
authorities, LINks (Local Involvement Networks), Patient Advice Liaison Services(PALS), comments from the public etc. The Commission has the power to remove
registration from any trust failing to comply with essential standards. Nevertheless
there have been concerns that the organisation is toothless after reports of poor care
following visits.
Trusts are measured against a number of essential standards which they state are
based on the type of care provided rather than systems and processes.
Patients can expect to be involved and told what is happening at every stageof their care
Patients can expect care, treatment and support which meets their needs Patients can expect to be safe
Patients can expect to be cared for by qualified staff
Patients can expect their hospital to constantly check the quality of itsservices
(Care Quality Commission, 2011b).

The dimensions are limited in some aspects of overall patient experience,particularly around empathy and the complexities of communications.
2.3. Patient surveys on behalf of the Department of Health (DoH)
Patient surveys are underpinned by research to determine priorities that the public
place on service elements. Since 1997 hospitals in the UK have been required tocarry out a survey annually. The CQC determines the core questions which fall into
seven categories: admission to hospital; hospital and ward; staff; care and
treatment; operations and procedures; leaving hospital and overall. These can be
augmented at local level though this opportunity is treated with caution since the
core questionnaire is unduly long. Unfortunately, more recently there has been a
tendency to incorporate questions of a political essence such as waiting times,
cleanliness and mixed sex wards going against the spirit of the original framework
(Goodrich & Cornwell, 2008).
The survey is annual through which longitudinal trends can be extracted at each
trust. One of the major challenges of the survey is that a patient merely registersdissatisfaction with an element rather than being able to explain what they were
unhappy about (Coulter et al., 2009; Goodrich & Cornwell, 2008; Richards & Coulter,
2007).
Vigilance is also recommended since studies have indicated that even where a
patient has perceived their care as excellent they have often experienced a number
of problems (Goodrich & Cornwell, 2008). This may be because of the inherent
trust that patients have in the medical profession (Richards & Coulter, 2007) and do
not feel in a position to be critical.
2.4. Quality Outcomes Framework.
This process assesses general practice on behalf of the Department of Health. It is
carried out by panels of clinicians and lay people who visit each general practice on
an annual basis. It provides the basis for an incentive programme through scoring
management of common chronic diseases; practice organisation, how patients view
their experience and extra services offered. The QOF accounts for up to 20% of the
income of participating practices.
The process has been criticized for removing the autonomy of general practitioners;
micromanagement by the state; ignoring elements patients value such as trust and
results in coercing patients to accept specific treatments (Mangin & Toop, 2007).

4. Critique of SERVQUAL
Until the development of SERVQUAL in 1985 by Parasuraman et al. the
measurement of service quality traditionally came from theory around the marketing
of goods. The SERVQUAL model employs the theoretical framework of expectation
versus satisfaction and measures five gaps:
Management perceptions of customer expectation and actual customer
expectation
1. Management perceptions of customer expectations and company stated
service specification
2. Company stated service specification and service delivery
3. Company stated service specification and the external communication of this
4. Customer expectation and customer experience. This gap is influenced by
gaps 1-4
(Parasuraman et al., 1985)
It comprises first a set of 22 questions which asks the respondent the extent to which
the firm delivering the service should possess each feature followed by a similar
series of 22 questions, this time asking the extent to which the respondent feels the
firm possesses each item. It does not, however, ask respondents to place the
priority they would place on each item. With almost 200 questions to answer, the
process is lengthy and potentially unwieldy. The first model comprised 10 factors
(Table 1) In either model, with almost 200 questions to answer, the process was
lengthy and potentially unwieldy.

Table 1 SERVQUAL Determinants of service quality(Ten dimensions)DIMENSION DEFINITION
Reliability Consistency of performance and dependability. It means that the firm performsthe service right for the first time. It also means that the firm honours its promises.Specifically, it involves:
- Accuracy in billing;- Keeping records correctly
- Performing the service at the designated time.Responsiveness Willingness or readiness of employees to provide service. It involves timeliness
of service:- Mailing a transaction slip immediately;- Calling the customer back quickly;- Giving prompt service (e.g. setting up appointments quickly).
Competence Possession of the required skills and knowledge to perform the service. Itinvolves:
- Knowledge and skill of the contact personnel;- Knowledge and skill of operational support personnel;- Research capability of the organisation, e.g. securities brokerage firm.
Access Approachability and ease of contact. It means:- The service is easily accessible by telephone (lines are not busy and
they dont put you on hold);
- Waiting time to receive service (e.g. at a bank) is not excessive;- Convenience hours of operation;- Convenient location of service facility.
Courtesy Politeness, respect, consideration and friendliness of contact personnel (includingreceptionists, telephone operators etc.). It includes:
- Consideration or the consumers property (e.g. no muddy shoes on thecarpet)
- Clean and neat appearance of public contact personnel.
Communication Keeping customers informed in language they can understand and listening tothem. It may mean that the company has to adjust its language for differentconsumers increasing the level of sophistication with a well-educated customerand speaking simply and plainly with a novice. It involves:
- Explaining the service itself;- Explaining how much the service will cost;
- Explaining the trade-offs between service and costly;- Assuring the consumer that a problem will be handled.
Credibility Trustworthiness, believability, honesty. It involves having the customers bestinterests at heart. Contributing the credibility are:
- Company name;- Company reputation;- Personal characteristics of the contact personnel;- The degree of hard sell involved in interactions with the customer.
Security Freedom from danger, risk or doubt. It involves:- Physical safety (Will I get mugged at the automatic teller machine?);- Financial security (Does the company know where my documents are?);- Confidentiality. (Are my dealings with the company private?
Understanding/Knowing the
customer
Making the effort to understand the customers needs. It involves:- Learning the customers specific requirements;
- Providing individualised attention;- Recognising the regular customer.
Tangibles Physical evidence of the service:- Physical facilities;- Appearance of personnel;- Tools or equipment used to provide the service;- Physical representations of the service - plastic credit card or a bank
statement;- Other customers in the service facility.
(Parasuraman et al., 1985)

A later piece of work refined these to five dimensions (Table 2). This was based on
a study of 200 respondents, each of whom had used one of the five sectors included
in the research appliance repair/maintenance, retail banking, long-distance
telephone, securities brokerage and credit cards.

4.1. Challenging the Model
SERVQUAL is widely accepted as having made an enormous contribution to theory
around the measurement of service quality with claims that service quality has
become SERVQUAL. (Woodall, 2001, pg 596). It has, nevertheless, received
considerable critical analysis over the years. A review of extent literature raises a
number of concerns as described in Table 3. Omitted from these are a number of
potential methodological flaws.
4.1.1. Sectors Used - The authors state the firms they used represented both high
and low contact services; a debatable claim since high contact services are those
where transactions involve consumers and staff in complex interactions as
contextualised by the theory of co-creation (Vargo & Lusch, 2004). None of those
selected acknowledge the true complexities of professional services such as health

care where human elements such as courtesy, empathy or the communication skills
which are so important, especially where services are tailored to individual needs.
4.1.2 Sample - the sample of participants used in the work was limited. Fourteen
senior executives were interviewed across the four sectors. No front of house staff
were included. This risks losing rich and valuable data gleaned from their working
relationships with consumers. The later work to refine the model in 1988 targeted
just 200 respondents across the sectors collectively. For such a seminal piece of
work, this was a modest sample
4.1.3. Dimensions Dimensionality is a pragmatic way of measuring service quality
but a question lies in the nature of the dimensions. The influence of SERVQUAL is
diminished since sector specific dimensions were omitted from the research, only
general dimensions being deemed relevant (Parasuraman et al., 1985). While this
ensures a more flexible model across services, it misses some key components
relevant to specific sector contexts where items are not transferable from one sector
to another.
4.1.4. Validity of Expectations - Fundamental to the model is the gap between
expectations and perceptions, a concept which has attracted debate over its validity
(Robinson, 1999; Buttle, 1996; Cronin & Taylor, 1994; Babakus & Boller, 1992).
Problems arise around what people base their expectations on, when they form them
or whether these can be carried across sectors. Expectations can change with
familiarity (Rosen et al., 2003) which will alter perceived level of quality and affect
the validity of the disconfirmation model on which SERVQUAL is based. Experience
is also polysemic with a variety of meanings and using the concept alone is too
simplistic.
An alternative model is SERVPERF (Cronin & Taylor, 1994) which, while based on
the same 22 attributes as SERVQUAL,questions the concept of comparing
experience with expectation (Cronin & Taylor, 1994). The model is more
parsimonious, removing expectation and relying on data around performance only.
This pragmatic advantage over SERVQUAL cannot be ignored since only one
questionnaire is required (Jain & Gupta, 2004).

Table 3 Validity of SERVQUAL
AUTHORS LIMITATIONS
(Ladhari, 2009) SERVQUAL limitations: scoring, reliability, validity, emphasis on process rather thanoutcome, hierarchical service quality constructs, reflective scales, use of generic scalefor all sectors, applicability for online use and culturally. It can be useful if adapted forspecific industry use and it is validated through reliability and validity analysis.
(Rhee & Rha,2009)
SERVQUAL does not explore the validity of its constructs in the public sector whereservice issues are more complex and there is a greater diversity of stakeholders.
(Carrillat et al.,2007)
SERVQUAL and SERVPERF are of equal validity for diagnostic purposes, althoughSERVQUAL required more adaptation for different sectors. The choice between thetwo should be based on if the tool is to be used for diagnostic uses andoperationalisation taking into consideration the length of the SERQUAL model.
(Jain & Gupta,2004)
SERVPERF is simpler to use and explains variations in overall quality service,SERVQUAL is better diagnostically. SERVPERF is preferable for assessing overallservice quality; SERVQUAL is superior in identifying quality shortfalls.
(Kilbourne etal., 2004)
The use of SERVQUAL in care homes across the USA identified limitations in theoriginal version Some items were irrelevant. They conclude that SERVQUAL isconvenient and reliable in measuring quality across countries, but more work is
needed in cross national reliability in healthcare.(G.S.Sureshchandaret al., 2002b)
SERVQUAL model overlooks key factors of service quality: the core service,systemization/standardization of service delivery (non-human) and social responsibilityof the provider
(Winsted,2000)
SERVQUAL doesnt ask what consumers want service providers to do; constructs arepredetermined; service literature is still confused about the meanings of some ofSERVQUAL constructs; it is not as effective as service specific models
(Robinson,1999)
While SERVQUAL has been the preferred method of measuring service quality sincethe 1980s, too many questions arise concerning its efficacy for it to retain its primeposition. Concerns include: generalisability across sectors; the measurement ofcustomer satisfaction rather than service quality; the wording of questions, therelevance of measuring expectation.
SERVQUAL has a major impact on business. But there are limitations around validity
of constructs; doubts consumers assess quality as perception v expectations (hey donot consider expectations); dimensions are not universal; moments of truth can varyfrom event to event; use of two questionnaires causes confusion.
(Buttle, 1996) There is little evidence of the validity of customers evaluating service quality based onexpectation versus performance. Concern is also raised about the global use of thedimensions across sectors.
(Cronin &Taylor, 1994)
Published SERVPERF model as an alternative to SERVQUAL. Saw the SERVQUALmodel as too subjective relying on the transitory element of customer satisfactionrather than long term service quality.
(McAlexanderet al., 1994)
SERVPERF is superior as predictive tool and looks at weighting performance items.They question the inclusion of SERVQUALS expectations in health care whereexpectations are high across all dimensions; they also consider it the more useful as adiagnostic tool for managers.
(Carman,
1990)
The dimensions of SERVQUAL cannot be applied cross industry.

5. Dimensionality
Understanding dimensionality underpins everything else in evaluating service quality.
This section explores the dimensions identified by literature and their relation to
functional and technical elements of service. It also reflects on the importance of
relationships in the process.

5.2. Defining Dimensions
Theorists have come up with numerous variations of these core dimensions, (Table
4) and while similarities do exist, there is no overall consensus about them, or
whether they can be generalised across sectors (Brady & Cronin, 2001). Some
have attempted to categorise dimensions into the Nordic approach, technical and
functional, or the US school of thought as in SERVQUAL, but this is an
oversimplification where neither fully define the service quality construct (Brady &
Cronin, 2001). Dimensions often comprise a number of items, each of which may
influence more than one dimension. While these offer a more detailed and well
defined construct, they do not overcome the complexities of use across sectors.
While authors present a variety of sets of dimensions they see as relevant (Table 5),
there is some consensus that the technical and functional dimensions come together
to contribute to the overall experience in health care (Dagger et al., 2007; Zineldin,
2006; Lytle & Mokwa, 1992). These have been described as care and cure (Conway
& Huffcutt, 2003) where care is conceptualised as the functional elements such asthe environment, interactions, comfort etc and are deemed as contributing to the
overall concept of service quality (McAlexander et al., 1994). Being at ease with an
employee can reduce anxiety as well as make the customer feel respected (Lloyd,
2009; Macintosh, 2009). This is particularly relevant in the case of health care where
dignity and respect are high on the agenda and often quoted in official guidelines
and regulations. Where comfort or intimacy exists, it is more likely that the customer
will provide the necessary information to help the provider deliver the most
appropriate service (Lloyd, 2009) especially in health care where patients are
anxious and may feel uneasy in confiding everything or fail to identify important
snippets of information.
Dimensionality in health care is difficult to contextualise as it is such a complex
service. It can be delivered from a range of environments including hospitals, clinics,
and surgeries and even from the home. It includes every citizen since everyone is a
potential patient and it covers a huge range of services and professionals.
WHO use the word responsiveness to express a patients experience of health care
in its widest context, defining this as including: dignity, autonomy, confidentiality,
information, prompt attention, access to social support, quality of amenities and
choice (Gostin et al., 2003).
Key to health care are respect and dignity, each of which features surprisingly
infrequently in extent academic models. Together, these allow patients to feel in
control, valued, confident, comfortable and able to make decisions for themselves
(Scrivener, 2011). These omissions need addressing to reflect the priority most UK
Government papers referring to health care place on them. Nor is privacy mentioned
which is a basic human right and is an antecedent of dignity (Tabak & Ozon, 2004).

5.2. Relationships rapport, respect and trust
The nature of services makes the proposition of value and quality especially
unpredictable. There are many opportunities for something to go wrong when the
service provider and the customer interact, when both parties experience and
respond to each others mannerisms, attitude, competence, mood, dress, language,
and so forth. (Berry et al., 1988 p.38). Service is based on the interaction between
two parties to create value and the importance of them, especially in professional
and high contact services is clear (Lehtinen, 1991; G.S. Sureshchandar et al.,
2002), since interactions help build professional relationships which should ultimately
lead to trust. Drawing on literature suggests a basic hierarchy of constructs (Fig 1)
although these will vary according to the nature of the service.
Fig 1 Hierarchy of Constructs
Compiled by the author
5.2.1. Respect and Rapport
Of the five dimensions central to SERVQUAL, four of these are based on the human
element of service: responsiveness, reliability, assurance and empathy of which
responsiveness and reliability have been seen to be especially crucial (Rhee & Rha,
2009; Angelopoulou et al., 1998; Berry et al., 1988; Parasuraman et al., 1988).
Missing from the model, however, are rapport and respect which, although may be
implicit within assurance or empathy (polite staff and understanding/knowing theclient), they should be first order constructs in their own right (Macintosh, 2009) and
explicit as dimensions.
Respect is giving attention to a person and valuing them, understanding the
individual, responsibility, an interest in humanity and acceptance of differences in
people beyond tolerance (Abbott, 1991). Rapport goes much further than polite
staff and understanding or knowing the client as defined by SERVQUAL. It has been

deconstructed to include mutual self-disclosure (shared information and open
communications); extras (responses to simple requests for customisation or
exemplary behaviours) civility/courtesy (Macintosh, 2009) and interaction (Gremler &
Gwinner, 2000). It creates a bond and cohesiveness which in turn generates trust
and can help consumers relax (Macintosh, 2009).
To ignore the significance of either respect or rapport leaves the organisation
vulnerable to poor relationships with the customer/client, potentially breaking down
levels of trust.
5.2.2. Credence and Trust
Trust is a construct that should be inherent in all professional services but is one that
does not appear as a dimension in its own right in much of the literature. This may
be because it is assumed that the customer has a right to be able to trust the
integrity, knowledge, experience, skills and expertise of the professional providing
the service. Confidence in expertise, dependability of staff and familiarity are each
antecedents to trust (Macintosh, 2009). The fact that rofessionals are bound by
regulations set by governing bodies such as the UK Law Society, General Medical
Council, and Royal Colleges helps in building confidence for customers/clients.
Perhaps more than any other sector, health care is one sector that is highly
specialised and personal demanding immense trust leading to an assumption that
this construct should be reflected in dimensionality. Quality in health care has been
conceptualised as the provision of appropriate and technically sound care that
produces the anticipated effect. (McAlexander et al., 1994 p.34). The clinical
procedures and outcomes are the shared aims of the patient and physician and are
seen as an implicit rather than explicit element of services which patients feel theyare not qualified to evaluate (Rashid & Jusoff, 2009; Conway & Huffcutt, 2003).
They, therefore, depend on being able to have a trust in the expertise of the
professional. They seek other prompts such as the soft elements, which although
subjective are easier to assess. Much literature has been based on these peripheral
(functional) items (Lytle & Mokwa, 1992), but debate continues around how they are
defined (table 5) and their subjectivity compared with technical processes and
outcomes which are reported through performance indicators and used for
accountability, regulation and accreditation (Rubin et al., 2001).

6. Methodology
The research uses multiple methods to exploit the advantages of both qualitative and
quantitative techniques (Johnson & Onwuegbuzie, 2007). It is the approach
favoured by pragmatists where all that matters is whether a strategy works
satisfactorily. There is no distinction between theory and practice. This
epistemology is gaining increasing amounts of attention in social sciences which is
becoming more complex and dynamic with an increasing need for a more pluralistic
approach. It uses the most appropriate means to understand the question and solve
the problem and is ideally suited to the health care sector where structures,
processes and patterns are complex (Lowe et al., 2005).
Qualitative techniques were used to generate in-depth data about the meaning of
quality to both service users and providers. This data was then be used as the basis
of a questionnaire distributed across a wide demographic sample.
6.1. Qualitative Process
6.1.1. Interviews
A literature review was followed by a series of interviews to understand how quality
is currently measured and what issues staff believe are important to patients/carers.
These were carried out with representatives from stakeholders, managers and
clinicians including:
the chair of large teaching hospital trust
director of facilities of a large teaching hospital trust
the regional director of the Care Quality Commission
a local MP
a local authority representative
medical director of a district general hospital
matron of a hospice
accident and emergency receptionist
a senior nurse with responsibility for cancer patients
a director of nursing
a physiotherapist
Each interview was semi-structured and lasted approximately one hour in length.
The aim was to understand what priorities organisations place on service quality
elements and to understand measures taken to evaluate these qualities
6.1.2. Focus groups
A series of eight focus groups comprising patients, carers and general members of
the public was held. These included groups comprising people with multiple needs,
young mothers, elderly, a user group at a local surgery and general members of the

public and represented a wide age range from early 20s upwards. Members were
selected from personal contacts and recommendations from organisations
comprising the health economy in Greater Manchester. The objective was to
discuss participants own ideas about the priorities they would apply to elements of
quality (Cohen & Mallon, 2001).
6.1.3. Analysis
The interviews and group discussions were digitally recorded and later transcribed.
Copies were sent to the interviewees and to at least one member of each focus
group to ensure that they were an accurate reflection of what had taken place. In the
case of the groups which comprised participants with multiple and complex needs
and the elderly, escorts who were present were asked to check for reliability on
behalf of the group members. The transcripts were then coded via open coding and
against SERVQUAL to draw out themes and items which were then used in the
design of a questionnaire. This was an iterative process as the complexity of data
required revisits in order to ensure reliability and effectiveness in the coding. Thiswas especially the case when transcribing groups comprising participants who had
complex needs and for whom communication was difficult.
An earlier career in the NHS equipped the researcher with experience in
communicating with staff at all levels and in dealing with sensitive issues among a
wide cross-section patients and carers.
6.2. Quantitative Process
6.2.1. Distribution of Questionnaires
A self-administered questionnaire was designed comprising seven themes with atotal of 104 items derived from the qualitative data. Respondents were asked to rate
the importance they placed on each item on a seven point Likert scale ranging from
not so important to very important.
The questionnaire was designed with the support of two senior academics and then
piloted twice among personal contacts.
As health care is relevant to everyone it was important the sample for distribution
comprised a wide demographic. Anyone over the age of 18 was deemed relevant.
This age was chosen as a cut off as approaching anyone under 18 would create
ethical issues.
Distribution was via a number of channels:
Snowballing techniques through personal contacts
Convenience sampling using personal contacts of the researcher
A database 950 from the voluntary sector based in the north east of
Manchester

A national database of 5,500 taken from mail order customers and
representing all socio-economic groups and demographics
More than 1,100 responses were received.
6.2.2. Analysis
At the time of writing analysis of the quantitative work had not been completed.
SPSS will be used to complete a factor analysis and produce regression tables. The
data will ultimately confirm or falsify dimensions currently used in the evaluation of
service quality in health care and will lead to the development of an instrument which
can be adapted for use in clinics, local doctors surgeries or hospitals.
7. Results
The results discussed here are interim since only data from the qualitative work are
available.
The dimension that featured most prominently was aligned with SERVQUALs
empathy. When deconstructed into items to reflect comments made by participants,
the open coding suggested the factor was far more complex than suggested by
either SERVQUALs original model of ten elements, or the later model of five. The
open coding broke the dimension down into five distinct items: attitude, reception,
empathy, respect and privacy. The last two of these reflect the importance literature
places on each as dimensions important to professional services. Neither is made
distinct in the SERVQUAL model.
Assurance also received high scores and was easier to assimilate with both
SERVQUAL versions, although the inclusion of polite staff and staff getting supportin the refined model of five dimensions did not fit with the open coding which focused
mainly on trust and safety.
The most apparent omission within either SERVQUAL model was communications.
This appeared as a factor in its own right within open coding, featuring third in
priority. It proved to be a complex factor breaking down into 15 individual items.
See Appendix 2.
Access to services was yet another factor which didnt easily fit within the refined
SERVQUAL model where it was represented as simply convenient hours are in
place within the empathy factor, although it did appear independently in the originalmodel. Yet again, open coding revealed it to be a dimension high on respondents
agendas and one which comprised several individual items (appendix 2).
There was some synergy with tangibles, although health care raises an extra item
with the provision of food. Responsiveness and reliability were also aligned fairly
closely with SERVQUAL.

These interim results suggest a degree of synergy between the original SERVQUAL
model with 10 dimensions. They do not, however, reflect the complexity of each
with reference to health care.
8. Limitations
It is likely that everyone has contact with health services at some part of their lives
which means that it is not viable to reach every potential user group. Some groups
were over represented, while others lacked representation. In the qualitative work,
focus groups were, in the main, from north east Manchester and despite the high
levels of black and minority ethnic (BME) groups in the area, these were not
included, largely due to potential language difficulties and access problems where
community members are less likely to participate in mainstream projects.
Surprisingly few were included in the national database or the local voluntary sector
for the quantitative work.
9. Ethics
The nature of the work was very sensitive where a number of respondents were
reflecting on the circumstances of serious illness, or even death. Ethical approval
was obtained from the National Research Ethics Committee North West for generic
coverage across all sites. Focus group participants were asked to sign a form
setting out the purpose of the study and where it is likely to be published. A similar
explanation was included with the questionnaire the completion of which signified
permission for inclusion in the study. All data has been treated confidentially and in
the case of the qualitative work, anonymously.

10. Contribution to Knowledge
There has been little work done in developing new concepts for the measurement of
service quality since the development of SERVQUAL 25 years ago. Evidence
supports the view that the model is not ideal for general cross-sector usage and a
gap exists, particularly in the provision of a service specific framework bespoke to
health care. This is an area of immense topical relevance of which every member of
the population is a stakeholder. The aim of the study is to overcome this anomaly by
contextualising service quality in a health care setting, thus adding to the theoretical
debate. It marries local strategic decision making with contemporary Government
policy which clearly sets out a direction where patients are central to service delivery,
focus is placed on quality and competition is likely to become a feature. The aim of
the project is to tackle the miscellany of methods currently used in the sector by
developing a fresh diagnostic framework to evaluate quality and tailored to local
needs. In achieving this, it will help health care providers to identify failings and set
strategy in accordance with Government policy aspirations to improve patient
experience and in so doing establish themselves as a place of patient choice.
11. Conclusion
The evaluation of quality in health care is extremely complex and over recent years,
has become high on the Government agenda in the UK. Despite this, there remain
concerns about the overall issue of quality in this sector. While there is an
abundance of work carried out nationally, much of it is performance which, although
important, leaves room for more priority to be placed on the human elements of
quality.
As the most widely used operational model, SERVQUAL claims to be suitable forcross sector application, although further investigation suggests otherwise. It omits
some key dimensions and items which contribute towards overall patient experience
within health care, especially around professional relationships and communications
both of which are multifaceted with a number of second level items. It also ignores
basic constructs such as privacy, dignity and respect, each of which can be seen as
human rights (Gostin et al., 2003).
While recognising the effectiveness of using dimensionality in evaluating health care,
findings from the qualitative part of this project support the need for service specific
models to reflect the unique needs of the health care sector.
12. Future Research
More extensive research over if or how dimensions vary according to different user
groups would create an opportunity to develop evaluation instruments for individual
specialities. The principles of this research can also be extended to other sectors in
order to create sector specific tools for service evaluation.

There are also openings for further research into the relevance of customer service
versus service quality in a sector where patients (especially older ones) often
experience services in the long term giving them more experience allowing them to
judge long term quality more effectively rather than transactional and short term
customer service.
