Using discrete choice experiments to estimate a preference-based measure of outcome--an application to social care for older people.

This paper reports the results of a study that used discrete choice experiment (DCE) methodology to estimate quality weights for a of social care outcome measure. To reflect different states of need, a five-dimensional profile measure was developed. Experimental design techniques were used to derive a sample of states for which preferences were elicited. The DCE approach was employed to elicit values and regression techniques used to estimate a model that could predict index scores for all 243 possible outcomes. The utility model, estimated on the basis of 297 responses, had good test-retest reliability and converged with preferences elicited from a rating exercise.

Women's preferences for cervical cancer screening: a study using a discrete choice experiment.

OBJECTIVES: Recent policy recommendations for cervical screening include liquid-based cytology. This new approach could improve laboratory throughput, reducing the waiting time for test results. New guidelines also standardize the interval for screening, with women aged 25-50 offered screening every 3 years and women aged 50-64 every 5 years. Quantitative evidence on the preferences of women for alternative screening programs is limited; this study, therefore, elicits such preferences. METHODS: A postal questionnaire using a discrete choice experiment was mailed to 2,000 women in the Tayside Health Board region of Scotland. RESULTS: A response rate of 44 percent from those women who had previously had a smear was achieved. Women had a significant positive preference for reductions in recall rates and waiting time for results. Women preferred more frequent screening, particularly those aged 50+. Expected reductions in the chance of recall from the conventional Pap smear to the new liquid-based cytology were associated with a willingness to pay of pound 41. Women aged 50+ would be willing to pay pound 42 to increase the frequency of screening from every 5 to every 3 years. Service characteristics did not influence screening participation. CONCLUSIONS: Guidance to move to liquid-based cytology will meet women's preferences for fewer repeat cervical smears and should reduce waiting time for results. However, proposals to increase screening intervals for those aged 50+ are inconsistent with the preferences for this age group. From a policy perspective, our study results suggest that the changes in attributes of the service such as unsatisfactory smear rates and frequency of screening, will improve service efficiency without affecting participation rates.

Using discrete choice experiments to go beyond clinical outcomes when evaluating clinical practice.

BACKGROUND: This study builds on the results of a randomized controlled trial concerned with examining the effect of reducing waiting times on the health status of patients referred for non-urgent rheumatology opinion. No difference in clinical outcomes was found between a 'fast-track' and 'ordinary' appointment system. This suggests that rationing by waiting times is not detrimental to health. However, such an approach ignores the value patients attach to reducing waiting time. OBJECTIVES: To estimate the monetary value of reducing waiting time, as well as changes in duration of appointment and the introduction of a pain management service, in the provision of rheumatology services. METHODS: Discrete choice experiment (DCE). SETTING: The main outpatient clinic of the rheumatology service for the Lothian and Borders region. SUBJECTS: 262 patients who had received a specialist rheumatology opinion--73 had received fast-track treatment, 65 standard care and 124 were non-trial patients. RESULTS: A response rate of 71% was achieved. Patients valued a 9-week reduction in waiting time at 131 pounds sterling. However, the introduction of a pain management service was valued at 209 pounds sterling. Thus, the latter is of more value to respondents. Evidence was also found of the internal consistency and theoretical validity of the DCE approach. CONCLUSIONS: The reduction of waiting times is a central plank of NHS policy. Whilst a reduction in waiting time is of value, a pain management service is of more benefit than a 9-week reduction in waiting time. DCE were shown to be a potentially useful technique for valuing different aspects of health care interventions.

Modelling non-demanders in choice experiments.

Discrete choice experiments have the advantage that they can study preferences in health care where revealed preference data is not readily available. However, as a substitute for actual observed market led data, the experimental set-up for hypothetical situations must mimic the circumstances under which actual choices are made. One situation that a consumer/patient might face is an opt-out option. They might not choose to accept any of the positive actions available and as such will be a non-demander of the health care on offer. This paper explores issues raised in the modelling of such data within an experiment looking at women's preferences for cervical screening services.

Preferences for general practice jobs: a survey of principals and sessional GPs.

BACKGROUND: Many countries are experiencing recruitment and retention problems in general practice, particularly in rural areas. In the United Kingdom (UK), recent contractual changes aim to address general practitioner (GP) recruitment and retention difficulties. However, the evidence base for their impact is limited, and preference differences between principals and sessional GPs (previously called non-principals) are insufficiently explored. AIM: To elicit GP principals' and sessional GPs' preferences for alternative jobs in general practice, and to identify the most important work attributes. DESIGN OF STUDY: A discrete choice experiment. SETTING: National Health Service (NHS) general practices throughout Scotland. METHOD: A postal questionnaire was sent to 1862 principals and 712 sessional GPs. The questionnaire contained a discrete choice experiment to quantify GPs' preferences for different job attributes. RESULTS: A response rate of 49% (904/1862) was achieved for principals and 54% (388/712) for sessional GPs. Of responders, most principals were male (60%), and sessional GPs female (75%), with the average age being 42 years. All GPs preferred a job with longer consultations, no increase in working hours, but an increase in earnings. A job with outside commitments (for example, a health board or hospital) was preferable; one with additional out-of-hours work was less preferable. Sessional GPs placed a lower value on consultation length, were less worried about hours of work, and a job offering sufficient continuing professional development was less important. CONCLUSION: The differences in preferences between principals and sessional GPs, and also between different personal characteristics, suggests that a general contract could fail to cater for all GPs. Recruitment and retention of GPs may improve if the least preferred aspects of their jobs are changed. However, the long-term success of contractual reform will require enhancement of the positive aspects of working, such as patient contact.
