Using mixed methods research to explore the effect of an adaptation exercise on general population valuations of health states

Hypothetical versus experienced health state valuation: a qualitative study of adult general public views and preferences

OBJECTIVES

Responses from hypothetical and experienced valuation tasks of health-related quality of life differ, yet there is limited understanding of why these differences exist, what members of the public think about them, and acceptable resolutions. This study explores public understanding of, opinions on, and potential solutions to differences between hypothetical versus experienced responses, in the context of allocating health resources.

METHODS

Six focus groups with 30 members of the UK adult public were conducted, transcribed verbatim, and analysed using framework analysis. Participants self-completed the EQ-5D-5L, before reporting the expected consequences of being in two hypothetical EQ-5D-5L health states for ten years. Second, participants were presented with prior results on the same task from a public (hypothetical) and patient (experienced) sample. Third, a semi-structured discussion explored participants': (1) understanding, (2) opinions, and (3) potential resolutions.

RESULTS

Twenty themes emerged, clustered by the three discussion points. Most participants found imagining the health states difficult without experience, with those aligned to mental health harder to understand. Participants were surprised that health resource allocation was based on hypothetical responses. They viewed experienced responses as more accurate, but noted potential biases. Participants were in favour of better informing, but not influencing the public. Other solutions included incorporating other perspectives (e.g., carers) or combining/weighting responses.

CONCLUSION

Members of the UK public appear intuitively not to support using potentially uninformed public values to hypothetical health states in the context of health resource allocation. Acceptable solutions involve recruiting people with greater experience, including other/combinations of views, or better informing respondents.

Whom should we ask? A systematic literature review of the arguments regarding the most accurate source of information for valuation of health states

To determine and critically evaluate the arguments in the published literature regarding the most accurate source of information for valuation of health states: values based on experienced health states (patient values) or values based on described health states (general public values).

Future Directions in Valuing Benefits for Estimating QALYs: Is Time Up for the EQ-5D?

The widespread adoption of the EuroQol 5-dimensional questionnaire (EQ-5D) has been important for the comparability, transparency, and consistency of economic evaluations for informing resource allocation in healthcare. The objectives of this article were to (1) critically assess whether the widespread adoption of the EQ-5D and its time trade-off-based value sets to inform economic evaluation is likely to continue and (2) speculate about how benefits may be measured and valued to inform economic evaluation in the future. Evidence supports the use of the EQ-5D in many areas of health, but there are notable gaps. Furthermore, there has been interest among some policy makers in measuring changes in well-being, and in using common outcomes across sectors. Possibilities for measuring well-being alongside health can be achieved through bolt-on dimensions or an entirely new measure capturing both health and well-being. Nevertheless, there are significant concerns about the logic of estimating a common utility function. The development of online valuation methods has had a major impact on the field, which is likely to continue. We, however, recommend more allowance for respondents to consider their answers. There is an ongoing debate on the role of patient values or experience-based values. To date, this has seen limited take-up by decision makers and there are significant technical problems to obtaining representative and meaningful values. Policy makers and the general population must decide on the focus and scope of benefits that are incorporated into economic evaluation, and current evidence on this is mixed. In part, this will determine whether the widespread adoption will continue.

The role of enjoyment in exercise for people with arthritis: Four different viewpoints from a Q-methodology study

PURPOSE

There is limited research on the role of enjoyment of exercise among people with arthritis. The aim of the present study was to determine distinct viewpoints on exercise held by people with arthritis, and how enjoyment features in these viewpoints.

METHODS

A Q-methodology study was conducted, which involved two interviews with people with rheumatoid arthritis, osteoarthritis or ankylosing spondylitis (aged 20-85 years). In the first interviews, 11 participants helped to create the Q-set, a set of statements reflecting a range of existing views on exercising. In the second interviews, 12 participants (nine of the 11 from the first interviews and three others) ranked the Q-set on a forced quasi-normal distribution of agreement. A Q-method factor analysis was carried out to determine groupings of participants with similar views on exercise.

RESULTS

Four groupings were discovered, and defined in terms of rankings of statements and illustrative quotes from the ranking procedure. The first grouping had all changed their exercise habits after diagnosis with arthritis. The second grouping had a shared enjoyment for walking to stay healthy. The third grouping's viewpoints focused on knowledge about how much exercise they should carry out. The fourth grouping shared a sense of importance of being responsible for their health by exercising.

CONCLUSION

These findings provide information about the role that enjoyment plays in motivating people with arthritis to exercise, although enjoyment of exercise was not expressed by all participants. People with arthritis who share these viewpoints on exercise enjoyment may require different forms of advice regarding feasible and enjoyable exercise.
