The appropriate uses of qualitative methods in health economics

Content validity of the EQ-HWB and EQ-HWB-S in a sample of Italian patients, informal caregivers and members of the general public

BACKGROUND

The EuroQol Group recently developed two new instruments, the EQ Health and Wellbeing (EQ-HWB) and the EQ Health and Wellbeing short version (EQ-HWB-S). The EQ-HWB and EQ-HWB-S are intended to capture a broad range of health and broader quality of life aspects, which may be relevant to general public members, patients, their families, social care users and informal carers. This study assesses the content validity of the Italian version of the two instruments in a sample of Italian patients, social care users and informal carers.

METHODS

Participants were recruited using a convenience sampling approach. One-on-one interviews were carried out using video-conferencing interviews. A semi-structured topic guide was used to guide the interview procedures, with open-ended questions supplemented by probes. Participants were asked to explain important aspects of their health and quality of life, to complete the questionnaires and verbalize their thoughts.

RESULTS

Twenty participants comprising of patients (n = 9), informal carers (n = 6), and members of the general public (n = 5) participated to the study. Content validity was summarized into six main themes: comprehension, interpretation, acceptability, relevance, response options and recall period. All participants found the instruments easy or quite easy to understand and to respond to. Items were relevant for all three groups of participants, and response options appropriate.

CONCLUSIONS

The Italian version of the EQ-HWB showed content validity in measuring health and wellbeing in a mixed Italian population.

Evidence-Based Medicine in Otolaryngology Part XII: Assessing Patient Preferences

OBJECTIVE

To provide a contemporary resource to update clinicians and researchers on the current state of assessment of patient preferences.

DATA SOURCES

Published studies and literature regarding patient preferences, evidence-based practice, and patient-centered management in otolaryngology.

REVIEW METHODS

Patients make choices based on both physician input and their own preferences. These preferences are informed by personal values and attitudes, and they ideally result from a deliberative evaluation of the risks, benefits, and other outcomes pertaining to medical care. To date, rigorous evaluation of patient preferences for otolaryngologic conditions has not been integrated into clinical practice or research. This installment of the "Evidence-Based Medicine in Otolaryngology" series focuses on formal assessment of patient preferences and the optimal methods to determine them.

CONCLUSIONS

Methods have been developed to optimize our understanding of patient preferences.

IMPLICATIONS FOR PRACTICE

Understanding these patient preferences may help promote an evidence-based approach to the care of individual patients.

Evaluating unintended program outcomes through Ripple Effects Mapping (REM): Application of REM using grounded theory

Several evaluation models exist for investigating unintended outcomes, including goal-free and systems evaluation. Yet methods for collecting and analyzing data on unintended outcomes remain under-utilized. Ripple Effects Mapping (REM) is a promising qualitative evaluation method with a wide range of program planning and evaluation applications. In situations where program results are likely to occur over time within complex settings, this method is useful for uncovering both intended and unintended outcomes. REM applies an Appreciative Inquiry facilitation technique to engage stakeholders in visually mapping sequences of program outcomes. Although it has been used to evaluate community development and health promotion initiatives, further methodological guidance for applying REM is still needed. The purpose of this paper is to contribute to the methodological development of evaluating unintended outcomes and extend the foundations of REM by describing steps for integrating it with grounded theory.

A qualitative investigation of the health economic impacts of bariatric surgery for obesity and implications for improved practice in health economics

Obesity is an economic problem. Bariatric surgery is cost-effective for severe and resistant obesity. Most economic evaluations of bariatric surgery use administrative data and narrowly defined direct medical costs in their quantitative analyses. Demand far outstrips supply for bariatric surgery. Further allocation of health care resources to bariatric surgery (particularly public) could be stimulated by new health economic evidence that supports the provision of bariatric surgery. We postulated that qualitative research methods would elicit important health economic dimensions of bariatric surgery that would typically be omitted from the current economic evaluation framework, nor be reported and therefore not considered by policymakers with sufficient priority. We listened to patients: Focus group data were analysed thematically with software assistance. Key themes were identified inductively through a dialogue between the qualitative data and pre-existing economic theory (perspective, externalities, and emotional capital). We identified the concept of emotional capital where participants described life-changing desires to be productive and participate in their communities postoperatively. After self-funding bariatric surgery, some participants experienced financial distress. We recommend a mixed-methods approach to the economic evaluation of bariatric surgery. This could be operationalised in health economic model conceptualisation and construction, through to the separate reporting of qualitative results to supplement quantitative results.

How Qualitative Methods Can be Used to Inform Model Development

Decision-analytic models play a key role in informing healthcare resource allocation decisions. However, there are ongoing concerns with the credibility of models. Modelling methods guidance can encourage good practice within model development, but its value is dependent on its ability to address the areas that modellers find most challenging. Further, it is important that modelling methods and related guidance are continually updated in light of any new approaches that could potentially enhance model credibility. The objective of this article was to highlight the ways in which qualitative methods have been used and recommended to inform decision-analytic model development and enhance modelling practices. With reference to the literature, the article discusses two key ways in which qualitative methods can be, and have been, applied. The first approach involves using qualitative methods to understand and inform general and future processes of model development, and the second, using qualitative techniques to directly inform the development of individual models. The literature suggests that qualitative methods can improve the validity and credibility of modelling processes by providing a means to understand existing modelling approaches that identifies where problems are occurring and further guidance is needed. It can also be applied within model development to facilitate the input of experts to structural development. We recommend that current and future model development would benefit from the greater integration of qualitative methods, specifically by studying 'real' modelling processes, and by developing recommendations around how qualitative methods can be adopted within everyday modelling practice.

Discrete choice experiments of pharmacy services: a systematic review

Background Two previous systematic reviews have summarised the application of discrete choice experiments to value preferences for pharmacy services. These reviews identified a total of twelve studies and described how discrete choice experiments have been used to value pharmacy services but did not describe or discuss the application of methods used in the design or analysis. Aims (1) To update the most recent systematic review and critically appraise current discrete choice experiments of pharmacy services in line with published reporting criteria and; (2) To provide an overview of key methodological developments in the design and analysis of discrete choice experiments. Methods The review used a comprehensive strategy to identify eligible studies (published between 1990 and 2015) by searching electronic databases for key terms related to discrete choice and best-worst scaling (BWS) experiments. All healthcare choice experiments were then hand-searched for key terms relating to pharmacy. Data were extracted using a published checklist. Results A total of 17 discrete choice experiments eliciting preferences for pharmacy services were identified for inclusion in the review. No BWS studies were identified. The studies elicited preferences from a variety of populations (pharmacists, patients, students) for a range of pharmacy services. Most studies were from a United Kingdom setting, although examples from Europe, Australia and North America were also identified. Discrete choice experiments for pharmacy services tended to include more attributes than non-pharmacy choice experiments. Few studies reported the use of qualitative research methods in the design and interpretation of the experiments (n = 9) or use of new methods of analysis to identify and quantify preference and scale heterogeneity (n = 4). No studies reported the use of Bayesian methods in their experimental design. Conclusion Incorporating more sophisticated methods in the design of pharmacy-related discrete choice experiments could help researchers produce more efficient experiments which are better suited to valuing complex pharmacy services. Pharmacy-related discrete choice experiments could also benefit from more sophisticated analytical techniques such as investigations into scale and preference heterogeneity. Employing these sophisticated methods for both design and analysis could extend the usefulness of discrete choice experiments to inform health and pharmacy policy.

Economic Evaluation in Ethiopian Healthcare Sector Decision Making: Perception, Practice and Barriers

BACKGROUND

Globally, economic evaluation (EE) is increasingly being considered as a critical tool for allocating scarce healthcare resources. However, such considerations are less documented in low-income countries, such as in Ethiopia. In particular, to date there has been no assessment conducted to evaluate the perception and practice of and barriers to health EE.

OBJECTIVE

This paper assesses the use and perceptions of EE in healthcare decision-making processes in Ethiopia.

METHODS

In-depth interview sessions with decision makers/healthcare managers and program coordinators across six regional health bureaus were conducted. A qualitative analysis approach was conducted on three thematic areas.

RESULTS

A total of 57 decision makers/healthcare managers were interviewed from all tiers of the health sector in Ethiopia, ranging from the Federal Ministry of Health down to the lower levels of the health facility pyramid. At the high-level healthcare decision-making tier, only 56 % of those interviewed showed a good understanding of EE when explaining in terms of cost and consequences of alternative courses of action and value for money. From the specific program perspective, 50 % of the prevention of mother-to-child transmission of HIV/AIDS program coordinators indicated the relevance of EE to program planning and decision making. These respondents reported a limited application of costing studies on the HIV/AIDS prevention and control program, which were most commonly used during annual planning and budgeting.

CONCLUSION

The study uncovered three important barriers to growth of EE in Ethiopia: a lack of awareness, a lack of expertise and skill, and the traditional decision-making culture.

The Role of Qualitative Research Methods in Discrete Choice Experiments

Background. The use of qualitative research (QR) methods is recommended as good practice in discrete choice experiments (DCEs). This study investigated the use and reporting of QR to inform the design and/or interpretation of healthcare-related DCEs and explored the perceived usefulness of such methods. Methods. DCEs were identified from a systematic search of the MEDLINE database. Studies were classified by the quantity of QR reported (none, basic, or extensive). Authors (n = 91) of papers reporting the use of QR were invited to complete an online survey eliciting their views about using the methods. Results. A total of 254 healthcare DCEs were included in the review; of these, 111 (44%) did not report using any qualitative methods; 114 (45%) reported “basic” information; and 29 (11%) reported or cited “extensive” use of qualitative methods. Studies reporting the use of qualitative methods used them to select attributes and/or levels (n = 95; 66%) and/or pilot the DCE survey (n = 26; 18%). Popular qualitative methods included focus groups (n = 63; 44%) and interviews (n = 109; 76%). Forty-four studies (31%) reported the analytical approach, with content (n = 10; 7%) and framework analysis (n = 5; 4%) most commonly reported. The survey identified that all responding authors (n = 50; 100%) found that qualitative methods added value to their DCE study, but many (n = 22; 44%) reported that journals were uninterested in the reporting of QR results. Conclusions. Despite recommendations that QR methods be used alongside DCEs, the use of QR methods is not consistently reported. The lack of reporting risks the inference that QR methods are of little use in DCE research, contradicting practitioners’ assessments. Explicit guidelines would enable more clarity and consistency in reporting, and journals should facilitate such reporting via online supplementary materials.

How do individuals value health states? A qualitative investigation

Despite the importance of health state values in informing resource allocation in health care, there is arguably little known about how individuals value health. Previous studies have shown that a variety of non-health factors and beliefs are important in valuing health, but there is less evidence in the literature about how individuals' beliefs affect their preferences or what role non-health factors play in the process of forming preferences. This study investigated the thought processes of 21 U.K. based participants in March 2013 who valued health states using semi-structured interviews and a think-aloud protocol, with the aim to better understand the relationship between health states, the individual's underlying beliefs, and the individual's preferences. Participants followed several stages in valuing health. First, participants interpreted the health states more concretely, relying on their imagination and their experience of ill health. Participants judged how the concrete health problems combined with their personal interests, circumstances, and environment would affect them personally. Ultimately, participants valued health by estimating and weighing the non-health consequences of the health states. Six consequences were most frequently mentioned: activities, enjoyment, independence, relationships, dignity, and avoiding being a burden. At each stage participants encountered difficulties and expressed concerns. The findings have implications for methods of describing health, for example, whether the focus should be on health or a broader notion of well-being and capability. This is because the consequences are similar to the domains of broader measures such as the ICECAP measures for adults and older people, and the Warwick-Edinburgh Mental Wellbeing Scale. The findings suggest the need for testing whether individuals are informed about the health states they are valuing. Participants valued health by estimating the non-health consequences of health states and these estimates relied on individuals' beliefs about the interaction of the health state and their personal and social circumstances.

A discrete choice experiment studying students' preferences for scholarships to private medical schools in Japan

BACKGROUND

The shortage of physicians in rural areas and in some specialties is a societal problem in Japan. Expensive tuition in private medical schools limits access to them particularly for students from middle- and low-income families. One way to reduce this barrier and lessen maldistribution is to offer conditional scholarships to private medical schools.

METHODS

A discrete choice experiment is carried out on a total of 374 students considering application to medical schools. The willingness to receive a conditional scholarship program to private medical schools is analyzed.

RESULTS

The probability of attending private medical schools significantly decreased because of high tuition, a postgraduate obligation to provide a service in specific specialty areas, and the length of time of this obligation. An obligation to provide a service in rural regions had no significant effect on this probability. To motivate non-applicants to private medical schools to enroll in such schools, a decrease in tuition to around 1.2 million yen (US$ 12,000) or less, which is twice that of public schools, was found to be necessary. Further, it was found that non-applicants to private medical schools choose to apply to such schools even with restrictions if they have tuition support at the public school level.

CONCLUSIONS

Conditional scholarships for private medical schools may widen access to medical education and simultaneously provide incentives to work in insufficiently served areas.

Understanding Academic Clinicians' Decision Making for the Treatment of Childhood Obesity

BACKGROUND

Although most clinicians agree that obesity is a major problem, treatment rates remain low. We conducted this discrete choice experiment (DCE) to understand academic clinicians' decisions in treating childhood obesity.

METHODS

A total of 198 academic pediatric surgeons, pediatricians, family physicians, and allied health professionals were recruited from 15 teaching hospitals across Canada to participate in this DCE. Participants completed 15 tasks choosing between three obesity treatment scenarios to identify the scenario in which they would most likely treat pediatric obesity.

RESULTS

Latent class analysis revealed two classes with early intervention and late intervention preferences. Participants in the early intervention group (30%) were sensitive to variations in patient and family support. They would likely intervene if patients were obese, with normal lipid levels, were prediabetic, had high blood pressure, and when obesity was lifestyle associated. Late intervention clinicians (70%) were more likely to intervene if patients were morbidly obese, had abnormal lipid levels, required insulin for diabetes, had very high blood pressure, or when obesity impacted the patient's mental health. Simulations predicted that increasing colleague support for intervention, providing expert consultation, and mobilizing multidisciplinary support would increase the likelihood of treating pediatric obesity earlier from 16.1% to 81.5%.

CONCLUSIONS

This DCE was implemented to understand the factors clinicians use in making decisions. Most academic clinicians choose to intervene late in the clinical course when more-severe obesity-related morbidities are present. Increased support from colleagues, expert consultation, and multidisciplinary support are likely to lead to earlier treatment of obesity among academic clinicians caring for children.

Knowledge of and preferences for health insurance among formal sector employees in Addis Ababa: a qualitative study

Background

The Ethiopian health system has been undergoing through reforms. One of the reforms stipulated in policy documents is the introduction of health insurance at national level. Having the majority of the population without any experience of health insurance, investigating preferences and knowledge of the essence of health insurance among potential enrolees will provide vital information for policy makers. This formative study seeks to explore the knowledge and the preference for health insurance among formal sector employees in Addis Ababa.

Methods

Six focus group discussions with formal sector employees and five key informant interviews were conducted in Addis Ababa. A thematic analysis is used to analyse the results.

Results

The findings suggest that there is little knowledge about the concept and elements of health insurance. Some concepts such as, risk pooling and sharing are not well understood. The participants of the study considered health insurance as only a prepayment mechanism without risk sharing among members of the scheme. Regarding preference for health insurance, they have revealed quality of care as the most important factor. Comprehensiveness of benefit packages and the amount of premium level are also found to be concerns related to health insurance. However, a trade-off is also observed among premium level, comprehensive benefit packages, and healthcare facilities.

Conclusions

Improvements on availability and quality of services need to precede the introduction of social health insurance. There is also a need to work on awareness creation regarding concepts of health insurance. Further studies may explore if the knowledge gap is real or appeared due to reservations of the participants on the introduction of health insurance.

Assessing sufficient capability: A new approach to economic evaluation

Amartya Sen's capability approach has been discussed widely in the health economics discipline. Although measures have been developed to assess capability in economic evaluation, there has been much less attention paid to the decision rules that might be applied alongside. Here, new methods, drawing on the multidimensional poverty and health economics literature, are developed for conducting economic evaluation within the capability approach and focusing on an objective of achieving "sufficient capability". This objective more closely reflects the concern with equity that pervades the capability approach and the method has the advantage of retaining the longitudinal aspect of estimating outcome that is associated with quality-adjusted life years (QALYs), whilst also drawing on notions of shortfall associated with assessments of poverty. Economic evaluation from this perspective is illustrated in an osteoarthritis patient group undergoing joint replacement, with capability wellbeing assessed using ICECAP-O. Recommendations for taking the sufficient capability approach forward are provided.

Occupational Therapy can Flourish in the 21st Century — A Case for Professional Engagement with Health Economics

The view that the profession of occupational therapy will flourish in the 21st century was expressed before the banking system and financial market collapse in 2008. The profession now competes for scarce resources as austerity measures take effect. A summit meeting at the College of Occupational Therapists, in May 2013, discussed how to improve the profession's understanding and use of health economics. At this meeting, short-, medium-, and longer-term approaches were discussed, with the aim of improving the quality and quantity of publications on economic evaluations in occupational therapy. Despite an increasing number of publications on health economics across professions, occupational therapy lags behind. This focus is now vital for the profession.

A think aloud study comparing the validity and acceptability of discrete choice and best worst scaling methods

Objectives

This study provides insights into the validity and acceptability of Discrete Choice Experiment (DCE) and profile-case Best Worst Scaling (BWS) methods for eliciting preferences for health care in a priority-setting context.

Methods

An adult sample (N = 24) undertook a traditional DCE and a BWS choice task as part of a wider survey on Health Technology Assessment decision criteria. A ‘think aloud’ protocol was applied, whereby participants verbalized their thinking while making choices. Internal validity and acceptability were assessed through a thematic analysis of the decision-making process emerging from the qualitative data and a repeated choice task.

Results

A thematic analysis of the decision-making process demonstrated clear evidence of ‘trading’ between multiple attribute/levels for the DCE, and to a lesser extent for the BWS task. Limited evidence consistent with a sequential decision-making model was observed for the BWS task. For the BWS task, some participants found choosing the worst attribute/level conceptually challenging. A desire to provide a complete ranking from best to worst was observed. The majority (18,75%) of participants indicated a preference for DCE, as they felt this enabled comparison of alternative full profiles. Those preferring BWS were averse to choosing an undesirable characteristic that was part of a ‘package’, or perceived BWS to be less ethically conflicting or burdensome. In a repeated choice task, more participants were consistent for the DCE (22,92%) than BWS (10,42%) (p = 0.002).

Conclusions

This study supports the validity and acceptability of the traditional DCE format. Findings relating to the application of BWS profile methods are less definitive. Research avenues to further clarify the comparative merits of these preference elicitation methods are identified.

Qualitative exploration of the suitability of capability based instruments to measure quality of life in family carers of people with dementia

Background. In an ageing population, many individuals find themselves becoming a carer for an elderly relative. This qualitative study explores aspects of quality of life affected by caring for a person with dementia, with the aim of identifying whether capability based questionnaires are suitable for measuring carer quality of life. Methods. Semistructured interviews lasting up to an hour were conducted, November 2010-July 2011, with eight family carers of people with dementia. Interviews typically took place at the participants' homes and were recorded and transcribed verbatim. Framework analysis was used to code and analyse data. Domains from three capability based questionnaires (ICECAP-O, Carer Experience Scale, and ASCOT) were used as initial codes. Similar codes were grouped into categories, and broader themes were developed from these categories. Results. Four themes were identified: social network and relationships; interactions with agencies; recognition of role; and time for oneself. Conclusions. By identifying what affects carers' quality of life, an appropriate choice can be made when selecting instruments for future carer research. The themes identified had a high degree of overlap with the capability instruments, suggesting that the capabilities approach would be suitable for future research involving carers of people with dementia.

Design of Economic Evaluations of Mindfulness-Based Interventions: Ten Methodological Questions of Which to Be Mindful

Mindfulness-based interventions (MBIs) are being increasingly applied in a variety of settings. A growing body of evidence to support the effectiveness of these interventions exists and there are a few published cost-effectiveness studies. With limited resources available within public sectors (health care, social care, and education), it is necessary to build in concurrent economic evaluations alongside trials in order to inform service commissioning and policy. If future research studies are well-designed, they have strong potential to investigate the economic impact of MBIs. The particular challenge to the health economist is how best to capture the ways that MBIs help people adjust to or build resilience to difficult life circumstances, and to disseminate effectively to enable policy makers to judge the value of the contribution that MBIs can make within the context of the limited resourcing of public services. In anticipation of more research worldwide evaluating MBIs in various settings, this article suggests ten health economics methodological design questions that researchers may want to consider prior to conducting MBI research. These questions draw on both published standards of good methodological practice in economic evaluation of medical interventions, and on the authors’ knowledge and experience of mindfulness-based practice. We argue that it is helpful to view MBIs as both complex interventions and as public health prevention initiatives. Our suggestions for well-designed economic evaluations of MBIs in health and other settings, mirror current thinking on the challenges and opportunities of public health economics.

Exploring what lies behind public preferences for avoiding health losses caused by lapses in healthcare safety and patient lifestyle choices

Background

Although many studies have identified public preferences for prioritising health care interventions based on characteristics of recipient or care, very few of them have examined the reasons for the stated preferences. We conducted an on-line person trade-off (PTO) study (N=1030) to investigate whether the public attach a premium to the avoidance of ill health associated with alternative types of responsibilities: lapses in healthcare safety, those caused by individual action or lifestyle choice; or genetic conditions. We found that the public gave higher priority to prevention of harm in a hospital setting such as preventing hospital associated infections than genetic disorder but drug administration errors were valued similar to genetic disorders. Prevention of staff injuries, lifestyle diseases and sports injuries, were given lower priority. In this paper we aim to understand the reasoning behind the responses by analysing comments provided by respondents to the PTO questions.

Method

A majority of the respondents who participated in the survey provided brief comments explaining preferences in free text responses following PTO questions. This qualitative data was transformed into explicit codes conveying similar meanings. An overall coding framework was developed and a reliability test was carried out. Recurrent patterns were identified in each preference group. Comments which challenged the assumptions of hypothetical scenarios were also investigated.

Results

NHS causation of illness and a duty of care were the most cited reasons to prioritise lapses in healthcare safety. Personal responsibility dominated responses for lifestyle related contexts, and many respondents mentioned that health loss was the result of the individual’s choice to engage in risky behaviour. A small proportion of responses questioned the assumptions underlying the PTO questions. However excluding these from the main analysis did not affect the conclusions.

Conclusion

Although some responses indicated misunderstanding or rejection of assumptions we put forward, the results were still robust. The reasons put forward for responses differed between comparisons but responsibility was the most frequently cited. Most preference elicitation studies only focus on eliciting numerical valuations but allowing for qualitative data can augment understanding of preferences as well as verifying results.

The interim service preferences of parents waiting for children's mental health treatment: a discrete choice conjoint experiment

Parents seeking help for children with mental health problems are often assigned to a waiting list. We used a discrete choice conjoint experiment to model preferences for interim services that might be used while waiting for the formal assessment and treatment process to begin. A sample of 1,059 parents (92 % mothers) seeking mental health services for 4 to 16 year olds chose between hypothetical interim services composed by experimentally varying combinations of the levels of 13 interim service attributes. Latent Class analysis yielded a four-segment solution. All segments preferred interim options helping them understand how agencies work, enhancing their parenting knowledge and skill, and providing an opportunity to understand or begin dealing with their own difficulties. The Group Contact segment (35.1 %) preferred interim services in meetings with other parents, supported by phone contacts, frequent checkup calls, and wait-time updates. Virtual Contact parents (29.2 %) preferred to meet other parents in small internet chat groups supported by e-mail contact. Membership in this segment was linked to higher education and computer skills. Frequent Contact parents (24.4 %) preferred face-to-face interim services supported by weekly progress checks and wait time updates. Limited Contact parents (11.3 %) were less intent on using interim services. They preferred to pursue interim services alone, with contacts by phone, supported by fewer check-up calls and less frequent wait time updates. All segments were more likely to enroll in interim services involving their child.

Global Health Initiatives and aid effectiveness: insights from a Ugandan case study

Background

The emergence of Global Health Initiatives (GHIs) has been a major feature of the aid environment of the last decade. This paper seeks to examine in depth the behaviour of two prominent GHIs in the early stages of their operation in Uganda as well as the responses of the government.

Methods

The study adopted a qualitative and case study approach to investigate the governance of aid transactions in Uganda. Data sources included documentary review, in-depth and semi-structured interviews and observation of meetings. Agency theory guided the conceptual framework of the study.

Results

The Ugandan government had a stated preference for donor funding to be channelled through the general or sectoral budgets. Despite this preference, two large GHIs opted to allocate resources and deliver activities through projects with a disease-specific approach. The mixed motives of contributor country governments, recipient country governments and GHI executives produced incentive regimes in conflict between different aid mechanisms.

Conclusion

Notwithstanding attempts to align and harmonize donor activities, the interests and motives of the various actors (GHIs and different parts of the government) undermine such efforts.

How is Telemedicine perceived? A qualitative study of perspectives from the UK and India

Background

Improvements in communication and information technologies have allowed for the globalisation of health services, especially the provision of health services from other countries, such as the use of telemedicine. This has led countries to evaluate their position on whether and to what extent they should open their health systems to trade. This often takes place from the context of multi-lateral trade agreements (under the auspices of the World Trade Organisation), which is misplaced as a significant amount of trade takes place regionally or bi-laterally. We report here the results of a qualitative study assessing stakeholders' views on the potential for a bi-lateral trade relationship between India and the UK, where India acts as an exporter and the UK as an importer of telemedicine services.

Methods

19 semi-structured interviews were carried out with stakeholders from India and the UK. The themes discussed include prospects on the viability of a bi-lateral relationship between the UK and India on telemedicine, current activities and operations, barriers, benefits and risks.

Results

The participants in general believed there were good prospects for telemedicine trade, and that this could bring benefits to "importing" countries in terms of cost-savings and faster delivery of care and to "exporting" countries in the form of foreign exchange and quality improvement. However, there were some concerns regarding quality of care, regulation, accreditation and data security.

Conclusions

There is potential for trade in this type of health services to succeed and bring about important benefits to the countries involved. However, issues around data security and accreditation need to be taken into consideration. Countries may wish to consider entering bi-lateral agreements, as they provide more potential to address the concerns and capitalise on the benefits. Finally, this paper concludes that more data should be collected, both on the volume of telemedicine trade and on the impact it is having on health systems, as currently there is very limited data on this.

The potential for bi-lateral agreements in medical tourism: A qualitative study of stakeholder perspectives from the UK and India

Background

Globalisation has prompted countries to evaluate their position on trade in health services. However, this is often done from a multi-lateral, rather than a regional or bi-lateral perspective. In a previous review, we concluded that most of the issues raised could be better addressed from a bi-lateral relationship. We report here the results of a qualitative exercise to assess stakeholders' perceptions on the prospects for such a bi-lateral system, and its ability to address concerns associated with medical tourism.

Methods

30 semi-structured interviews were carried out with stakeholders, 20 in India and 10 in the UK, to assess their views on the potential offered by a bi-lateral relationship on medical tourism between both countries. Issues discussed include data availability, origin of medical tourists, quality and continuity of care, regulation and litigation, barriers to medical tourism, policy changes needed, and prospects for such a bi-lateral relationship.

Results

The majority of stakeholders were concerned about the quality of health services patients would receive abroad, regulation and litigation procedures, lack of continuity of care, and the effect of such trade on the healthcare available to the local population in India. However, when considering trade from a bi-lateral point of view, there was disagreement on how these issues would apply. There was further disagreement on the importance of the Diaspora and the validity of the UK's 'rule' that patients should not fly more than three hours to obtain care. Although the opinion on the prospects for an India-UK bi-lateral relationship was varied, there was no consensus on what policy changes would be needed for such a relationship to take place.

Conclusions

Whilst the literature review previously carried out suggested that a bi-lateral relationship would be best-placed to address the concerns regarding medical tourism, there was scepticism from the analysis provided in this paper based on the over-riding feeling that the political 'cost' involved was likely to be the major impediment. This makes the need for better evidence even more acute, as much of the current policy process could well be based on entrenched ideological positions, rather than secure evidence of impact.

Providing information to parents of children with mental health problems: a discrete choice conjoint analysis of professional preferences

We used discrete choice conjoint analysis to model the ways 645 children's mental health (CMH) professionals preferred to provide information to parents seeking CMH services. Participants completed 20 choice tasks presenting experimentally varied combinations of the study's 14 4-level CMH information transfer attributes. Latent class analysis revealed three segments. Open Access professionals (32.2%) preferred that intake workers automatically provide all parents with CMH information. They preferred information prepared by professional organizations and located at accessible settings such as public schools. They responded favorably to the internet as a source of information for parents. Controlled Access professionals (22.2%) preferred information that was approved and recommended by a child's therapist, prepared by an experienced clinician, and located at hospitals and CMH clinics. Process Sensitive professionals (45.6%) showed a stronger preference for active learning materials with parenting groups and therapist "coaching" calls supporting the knowledge transfer process. Simulations suggested that realizing the benefits of CMH information requires the development of knowledge transfer strategies that align the preferences of professionals with those of the families they serve.

Qualitative methodologies in health-care priority setting research

Priority setting research in health economics has traditionally employed quantitative methodologies and been informed by post-positivist philosophical assumptions about the world and the nature of knowledge. These approaches have been rewarded with well-developed and validated tools. However, it is now commonly noted that there has been limited uptake of economic analysis into actual priority setting and resource allocation decisions made by health-care systems. There seem to be substantial organizational and political barriers. The authors argue in this paper that understanding and addressing these barriers will depend upon the application of qualitative research methodologies. Some efforts in this direction have been attempted; however these are theoretically under-developed and seldom rooted in any of the established qualitative research traditions. Two such approaches - narrative inquiry and discourse analysis - are highlighted here. These are illustrated with examples drawn from a real-world priority setting study. The examples demonstrate how such conceptually powerful qualitative traditions produce distinctive findings that offer unique insight into organizational contexts and decision-maker behavior. We argue that such investigations offer untapped benefits for the study of organizational priority setting and thus should be pursued more frequently by the health economics research community.

Modeling the bullying prevention program preferences of educators: a discrete choice conjoint experiment

We used discrete choice conjoint analysis to model the bullying prevention program preferences of educators. Using themes from computerized decision support lab focus groups (n = 45 educators), we composed 20 three-level bullying prevention program design attributes. Each of 1,176 educators completed 25 choice tasks presenting experimentally varied combinations of the study's attribute levels. Latent class analysis yielded three segments with different preferences. Decision Sensitive educators (31%) preferred that individual schools select bullying prevention programs. In contrast, Support Sensitive educators (51%) preferred that local school boards chose bullying prevention programs. This segment preferred more logistical and social support at every stage of the adoption, training, implementation, and long term maintenance processes. Cost Sensitive educators (16%) showed a stronger preference for programs minimizing costs, training, and implementation time demands. They felt prevention programs were less effective and that the time and space in the curriculum for bullying prevention was less adequate. They were less likely to believe that bullying prevention was their responsibility and more likely to agree that prevention was the responsibility of parents. All segments preferred programs supported by the anecdotal reports of colleagues from other schools rather than those based on scientific evidence. To ensure that the bullying prevention options available reflect the complex combination of attributes influencing real world adoption decisions, program developers need to accommodate the differing views of the Decision, Support, and Cost Sensitive segments while maximizing the support of parents and students.

Affordability, availability and acceptability barriers to health care for the chronically ill: longitudinal case studies from South Africa

Background

There is an increasing burden of chronic illness in low and middle income countries, driven by TB/HIV, as well as non-communicable diseases. Few health systems are organized to meet the needs of chronically ill patients, and patients' perspectives on the difficulties of accessing care need to be better understood, particularly in poor resourced settings, to achieve this end. This paper describes the experience of poor households attempting to access chronic care in a rural area of South Africa.

Methods

A household survey (n = 1446 individuals) was combined with qualitative longitudinal research that followed 30 case study households over 10 months. Illness narratives and diaries provided descriptive textual data of household interactions with the health system.

Results

In the survey 74% of reported health problems were 'chronic', 48% of which had no treatment action taken in the previous month. Amongst the case study households, of the 34 cases of chronic illness, only 21 (62%) cases had an allopathic diagnosis and only 12 (35%) were receiving regular treatment. Livelihoods exhausted from previous illness and death, low income, and limited social networks, prevented consultation with monthly expenditure for repeated consultations as high as 60% of income. Interrupted drug supplies, insufficient clinical services at the clinic level necessitating referral, and a lack of ambulances further hampered access to care. Poor provider-patient interaction led to inadequate understanding of illness, inappropriate treatment action, 'healer shopping', and at times a break down in cooperation, with the patient 'giving up' on the public health system. However, productive patient-provider interactions not only facilitated appropriate treatment action but enabled patients to justify their need for financial assistance to family and neighbours, and so access care. In addition, patients and their families with understanding of a disease became a community resource drawn on to assist others.

Conclusion

In strengthening the public sector it is important not only to improve drug supply chains, ambulance services, referral systems and clinical capacity at public clinics, and to address the financial constraints faced by the socially disadvantaged, but also to think through how providers can engage with patients in a way that strengthens the therapeutic alliance.

Rationalising the 'irrational': a think aloud study of discrete choice experiment responses

Stated preference methods assume respondents' preferences are consistent with utility theory, but many empirical studies report evidence of preferences that violate utility theory. This evidence is often derived from quantitative tests that occur naturally within, or are added to, stated preference tasks. In this study, we use qualitative methods to explore three axioms of utility theory: completeness, monotonicity, and continuity. We take a novel approach, adopting a 'think aloud' technique to identify violations of the axioms of utility theory and to consider how well the quantitative tests incorporated within a discrete choice experiment are able to detect these. Results indicate that quantitative tests classify respondents as being 'irrational' when qualitative statements would indicate they are 'rational'. In particular, 'non-monotonic' responses can often be explained by respondents inferring additional information beyond what is presented in the task, and individuals who appear to adopt non-compensatory decision-making strategies do so because they rate particular attributes very highly (they are not attempting to simplify the task). The results also provide evidence of 'cost-based responses': respondents assumed tests with higher costs would be of higher quality. The value of including in-depth qualitative validation techniques in the development of stated preference tasks is shown.

The greatest happiness of the greatest number? Policy actors' perspectives on the limits of economic evaluation as a tool for informing health care coverage decisions in Thailand

Background

This paper presents qualitative findings from an assessment of the acceptability of using economic evaluation among policy actors in Thailand. Using cost-utility data from two economic analyses a hypothetical case scenario was created in which policy actors had to choose between two competing interventions to include in a public health benefit package. The two competing interventions, laparoscopic cholecystectomy (LC) for gallbladder disease versus renal dialysis for chronic renal disease, were selected because they highlighted conflicting criteria influencing the allocation of healthcare resources.

Methods

Semi-structured interviews were conducted with 36 policy actors who play a major role in resource allocation decisions within the Thai healthcare system. These included 14 policy makers at the national level, five hospital directors, ten health professionals and seven academics.

Results

Twenty six out of 36 (72%) respondents were not convinced by the presentation of economic evaluation findings and chose not to support the inclusion of a proven cost-effective intervention (LC) in the benefit package due to ethical, institutional and political considerations. There were only six respondents, including three policy makers at national level, one hospital director, one health professional and one academic, (6/36, 17%) whose decisions were influenced by economic evaluation evidence.

Conclusion

This paper illustrates limitations of using economic evaluation information in decision making priorities of health care, perceived by different policy actors. It demonstrates that the concept of maximising health utility fails to recognise other important societal values in making health resource allocation decisions.

Can urban methadone patients complete health utility assessments?

OBJECTIVE

To assess the ability of methadone maintenance treatment (MMT) patients to use two standardized health assessment tools to value health states related to chronic hepatitis C virus (HCV) infection and HCV treatment-associated side effects. An estimated 65-90% of MMT patients are chronically infected with HCV.

METHODS

We employed qualitative methods to explore how patients completed computerized rating scale assessments and standard gamble utility assessments by (1) having them discuss their responses in a think-aloud interview immediately after each health state assessment, and (2) allowing them the opportunity to recalibrate prior responses after considering subsequent health states.

RESULTS

MMT patients used the rating scale boundaries appropriately and used the standard gamble to rank the health states in an a priori logical order. A guided assessment approach that allowed recalibration provided additional insight into values assigned to the health states presented.

CONCLUSION

MMT patients are able to perform the tasks associated with rating scale assessments and standard gamble utility assessments of HCV health states.

PRACTICE IMPLICATIONS

These assessment methods should be considered as a means to elicit MMT patients' values for HCV treatment, since the treatment outcome is uncertain but it is likely that side effects will adversely affect current health.

Extrinsic goals and time tradeoff

BACKGROUND

The aim of this article is to investigate the extrinsic goals hypothesis in time tradeoff (TTO). The extrinsic goal of interest here is seeing children through to maturity. In TTO, the time it takes to attain this goal becomes a target life expectancy, with no trades happening below the critical value implied by the target, no matter how severe the health state.

METHODS

A combined quantitative and qualitative approach was used to elicit values for 4 EQ-5D states from 30 recent mothers. The qualitative analysis allowed the researchers to explore with participants whether a target life expectancy was being used.

RESULTS

The differences in the visual analogue scale and TTO scores of the mothers compared with the general population suggest that the mothers value life-years differently than the general population does. The finding was also consistent with the target life expectancy hypothesis. However, the interview data were not so strongly supportive of the target life expectancy hypothesis. Although some women suggested this had motivated their responses to the TTO, the interviews paint a more complicated and nuanced picture of what drives a person's responses to health valuation surveys.

CONCLUSIONS

A higher value was assigned to life-years relative to quality of life by recent parents, but there was no reduction in the willingness to trade per se. Parenthood affects how much one will trade for better health but not whether one will trade in the 1st place. This conclusion became apparent only when the qualitative and quantitative data were combined.

The relationship between reliability and size of willingness-to-pay values: a qualitative insight

In a previous paper, the reliability of willingness-to-pay (WTP) values was found to be an increasing function of the size of WTP expressed. Here, the results of a qualitative exercise conducted alongside this quantitative study are presented. The results of this exercise suggest that higher WTP values may require more thought from the respondent which, in turn, gives them greater stability. At low levels of WTP, values appear to be taken from a 'discretionary account', where expenditure is more volatile. Caveats to this result, and suggestions for future research, are considered in the discussion.

Are health services protecting the livelihoods the urban poor in Sri Lanka? Findings from two low-income areas of Colombo

Investing in pro-poor health services is central to poverty reduction and achievement of the Millennium Development Goals. As health care financing mechanisms have an important influence over access and treatment costs they are central to the debates over health systems and their impact on poverty. This paper examines people's utilisation of health care services and illness cost burdens in a setting of free public provision, Sri Lanka. It assesses whether and how free health care protected poor and vulnerable households from illness costs and illness-induced impoverishment, using data from a cross-sectional survey (423 households) and longitudinal case study household research (16 households). The findings inform policy debates about how to improve protection levels, including the contribution of free health care services to poverty reduction. Assessment of policy options that can improve health system performance must start from a better understanding of the demand-side influences over performance.

Scaling up health interventions in resource-poor countries: what role does research in stated-preference framework play?

Despite improved supply of health care services in low-income countries in the recent past, their uptake continues to be lower than anticipated. This has made it difficult to scale-up those interventions which are not only cost-effective from supply perspectives but that might have substantial impacts on improving the health status of these countries. Understanding demand-side barriers is therefore critically important. With the help of a case study from Nepal, this commentary argues that more research on demand-side barriers needs to be carried out and that the stated-preference (SP) approach to such research might be helpful. Since SP techniques place service users' preferences at the centre of the analysis, and because preferences reflect individual or social welfare, SP techniques are likely to be helpful in devising policies to increase social welfare (e.g. improved service coverage). Moreover, the SP data are collected in a controlled environment which allows straightforward identification of effects (e.g. that of process attributes of care) and large quantities of relevant data can be collected at moderate cost. In addition to providing insights into current preferences, SP data also provide insights into how preferences are likely to respond to a proposed change in resource allocation (e.g. changing service delivery strategy). Finally, the SP-based techniques have been used widely in resource-rich countries and their experience can be valuable in conducting scaling-up research in low-income countries.

Using participatory action research to build a priority setting process in a Canadian Regional Health Authority

Due to resource scarcity, every health system worldwide must decide what services to fund, and conversely, what services not to fund. In order to institute and refine a macro-level priority setting framework within a large, urban health authority in Alberta, Canada, researchers and decision makers together embarked on a participatory action research (PAR) project. The focus of this paper is the PAR process in this context, including reflections from PAR participants about the contribution of the research methodology to their own practice as health care managers and clinicians. The use of qualitative research in health economics--in this case, to refine the application of a macro-level priority setting model--is a relatively new advancement. PAR proved to be an appropriate and helpful approach to introducing a theoretically driven model of macro-level priority setting within a large, complex health organization. However, it is important that support for the change is sustained as long as necessary to embed the new practices into the organization.

Patients' preferences for healthcare system reforms in Hungary: a conjoint analysis

OBJECTIVES

To illustrate how conjoint analysis can be used to identify patient preferences for healthcare policies, and to measure preferences for healthcare reforms in Hungary.

DATA SOURCE/STUDY SETTING

Data was collected via a mail-based survey and a direct survey administered in a rheumatology out-patient centre in Flór Ferenc County Hospital, Budapest, Hungary (n = 86).

STUDY DESIGN

We designed and administered a conjoint analysis to the study population. Attributes and attribute levels were developed on the basis of key informant interviews and a literature review. Additional demographic, occupation and healthcare utilisation data were also collected using surveys. A mixed effects linear probability model was estimated holding respondent characteristics constant and correcting for clustering.

DATA COLLECTION

Conjoint analysis questionnaires were administered by a physician to 50 consecutive rheumatology patients in a clinic and an additional 36 were mailed by post.

PRINCIPAL FINDINGS

The response rate for the physician-administered survey was 98% (but 18% of these were excluded for inconsistent preferences) and 53% for the mail survey, leaving a final sample of 59. Regression results (R2 = 56.8%) indicated that patients preferred a health system that was not cost constrained (p = 0.003), was based on solidarity (p < 0.001) and where patients were empowered (p = 0.024). Further, they would choose a system with no choice of provider to avoid co-payments (p = 0.005).

CONCLUSIONS

This study demonstrates that patients have clear preferences for healthcare system policy. In order to develop evidence-based healthcare policy and to empower patients in the healthcare system, methods such as conjoint analysis offer a simple yet theoretically grounded basis for policy making.

"To enrol or not to enrol?": A qualitative investigation of demand for health insurance in rural West Africa

In spite of the fact that feeble levels of participation have long been identified as a major constraint to the successful long-term implementation of community-based health insurance (CBI) in low-income countries, evidence on determinants of enrolment in CBI is still lacking. The application of econometric modelling has provided a partial answer to the question, but on its own it has proved to be insufficient to guide policy making. This paper aims to fill this gap in knowledge using qualitative research methods. In-depth interviews with 32 household heads were conducted in the Nouna Health District, Burkina Faso, West Africa to assess determinants of enrolment in a newly established CBI scheme. The findings highlight that factors previously neglected in the literature, such as institutional rigidities and socio-cultural practices, play an important role in shaping the decision to enrol. The discussion of the findings focuses on the policy implications, offering concrete recommendations to maximise enrolment, within and beyond Burkina Faso.

Illuminating cases: understanding the economic burden of illness through case study household research

Understanding the economic burden of illness for households can inform pro-poor health and social protection policy, yet research is in its infancy and appropriate methods require further debate. Quantitative studies are powerful when applied to the right health policy questions, including the measurement of illness cost burden indicators. However, this paper argues that not all dimensions of economic burden can be measured easily, some dimensions relevant to policy, such as social actors' responses to illness and their strategies to cope with illness costs, cannot be reduced to quantitative indicators at all, and large-scale surveys may overlook context-specific processes operating at household level that influence people's paths in and out of poverty as a result of illness. This leaves scope for longitudinal case-study household research to enhance understanding of economic burden and provide additional policy insights on how to better protect households from cost burdens and improve resilience. Drawing on the experience of research in urban Sri Lanka, the paper sets out several comparative advantages of case study research in this area. First, it complemented household survey data by revealing the complex and dynamic nature of illness costs and how these cost patterns (for example, sudden cost peaks) influenced household ability to manage costs. Secondly, it improved understanding of vulnerability or resilience to illness costs by capturing the diverse resources, within and outside the household, used by people to cope with illness costs, and the social institutions and decision-making processes that influenced access to them. Thirdly, the cases enabled the research to develop a picture of the inter-connected factors mediating the impact of illness on livelihood outcomes.

Understanding consumers' preferences and decision to enrol in community-based health insurance in rural West Africa

This paper presents a qualitative investigation of consumers' preferences regarding the single elements of a community-based health insurance (CBI) scheme recently implemented in a rural region in west Africa. The aim is to provide adequate policy-guidance to decision makers in low and middle income countries by producing an in-depth understanding of how consumers' preferences may affect decision to participate in such schemes. Although it has long been suggested that feeble levels of participation may very well be an expression of consumers' dissatisfaction with scheme design, little systematic efforts have so far been channelled towards supporting such argument with empirical evidence. Consumers' preferences were explored through means of 32 individual interviews with household heads. Analysis used the method of constant comparison and was conducted by two independent researchers. Data from 10 focus group discussions provided an additional valuable source of triangulation. Findings suggest that decision to enrol is closely linked to whether the single elements of the scheme match consumers' needs and expectations. In particular, consumers justified decision to join or not to join the insurance scheme in relation to their preference for the unit of enrolment, the premium level and the payment modalities, the benefit package, the health service provider network and the CBI managerial structure. The discussion of the findings focuses on how understanding consumers' preferences and incorporating them in the design of a CBI scheme may result in increased participation rates, ensuring that poor populations gain better access to health services and enjoy greater protection against the cost of illness.

Classical versus relational approaches to understanding controls on a contract with independent GPs in South Africa

Contracts have played a central role in public sector reforms in developed countries over the last decade, and research increasingly highlights their varied nature. In low and middle income countries the use of contracts is encouraged but little attention has been paid to features of the setting that may influence their operation. A qualitative case study was used to examine different dimensions of a contract with private GPs in South Africa. Features of the contract are compared with the notions of classical and relational contracts. Formal aspects of the contract such as design, monitoring and resort to sanctions were found to offer little control over its outcome. The relational rather than classical model of contracting offered a more meaningful framework of analysis, with social and institutional factors found to play an important role. In particular, the individual nature of GP practices highlighted the role played by individual motivation where a contract exercised little formal control. Due to the similarity of factors likely to be present, results are argued to be relevant in many other LMIC settings, and policy-makers considering contracts for clinical services are advised to consider the possibility of experiencing a similar outcome.

Priority setting in health authorities: a novel approach to a historical activity

As resources in health care are scarce, health authorities and other health organizations are charged with determining how best to spend limited resources. While a number of formal approaches to priority setting within health authorities have been used internationally, there has been limited success with such activity, particularly across major service portfolios. This participatory action research project instituted a novel priority setting framework, coined macro-marginal analysis (MMA), in a fully integrated urban health region in Alberta, Canada. The focus of MMA is on identifying areas for service growth and areas for resource release, then determining, based on pre-defined, locally generated criteria, if actual shifts or re-allocation of resources should occur. For fiscal year 2002/03, the Calgary Health Region identified over 40 M dollars in resource releases (approximately 3% of the total budget), which were made available for servicing the deficit, and more importantly for our purposes, re-investing in service growth areas. The MMA framework is pragmatic in nature and has the ability to incorporate relevant evidence directly into the decision-making process. This work constitutes a significant advancement in health economics, and responds where previous priority setting approaches have failed in that it allows decision-makers to achieve genuine re-allocation of resources with the aim of improving population health or better meeting other important criteria.

Economic evaluation of specialist cancer and palliative nursing: Macmillan Evalution Study findings

Economic evaluation of specialist nursing interventions is challenging because of the complex nature of interventions and the difficulty of describing nursing outcomes in simple ways. This article discusses data from a study of Macmillan specialist cancer nursing. Resource-use data and nursing-outcome data were collated from 76 case studies of patients referred to 12 specialist cancer and palliative nursing teams (home-based and hospital-based) in the UK. Specific outcomes related to nursing were defined, and cost and nursing outcome data were analysed together. The data suggested that patients who reported better nursing outcomes had a higher proportion of specialist nursing interventions than those reporting poor nursing outcomes (45% versus 25%). Also, the overall pattern of health-care use was different for those patients who reported positive nursing outcomes. This suggests that positive nursing outcomes can influence patients' access to other health services. The data supported specific hypotheses regarding ways that specialist nurses can influence the cost-effectiveness of care. These data do not constitute a comparative evaluation study, as no control group was identified. Such results are nevertheless important as this type of data has not been gathered previously.

Citizens, their agents and health care rationing: an exploratory study using qualitative methods

This paper considers the application of the theoretical notion of a principal-agent relationship to societal health care decision making. Current literature sheds little light upon whether a citizen-agent relationship exists in health care, with ambiguity about whether citizens want agents to make rationing decisions on their behalf, and if so, who these societal agents might be. A qualitative approach, using semi-structured interviews as the main instrument of data collection and analysis by constant comparison, was used to explore these issues with groups of both citizens and their potential agents. The findings of the research suggest that citizens vary considerably in the extent to which they want to be directly involved in making rationing decisions. Important influences on this issue appear to be knowledge and experience, objectivity and the potential distress that denying care may cause. Agents, in contrast, view citizens as needing agents to make decisions for them and suggest that it is primarily the health authority's role to act in this capacity. It is, however, apparent that the citizen-agent relationship in health care is both imperfect and complex, with final decisions resulting from the interaction between the utility functions of the various actors in the health care system. In practice a system of equivocation can be envisaged in which different groups collude as they attempt to avoid the disutility associated with denying care, with the consequence that the impact of decisions taken on an explicitly societal or citizen basis may be relatively small.

The impact of health economics on healthcare delivery. A primary care perspective

With the increasing emphasis on providing efficient and equitable services from primary care and against a background of increasing demands on limited resources, economic theory seeks to facilitate both the direction of primary care and the decisions that are made within it. This paper argues that the impact of health economics, particularly at the microeconomic level, has been limited. This is because health economists have failed to recognise the importance of context, and also reflects their attempts to force reality into a disciplinary matrix which is not always accessible and acceptable to end users. Argument is made for a closer relationship between health economists and those who commission and deliver primary care. It is also desirable to develop pragmatic decision-making frameworks which draw upon economic concepts and principles but reflect the realities of the environment in which they are applied.
