Summary
Public preferences in healthcare priority setting often diverge from the quality adjusted life year (QALY) maximization model. People prioritize quality of life over maximizing QALYs, especially when treatment offers little improvement in health states.
Area of Science:
- Health economics
- Public health policy
- Decision science
Background:
- UK policy promotes public involvement in healthcare decision-making and priority setting.
- Health economists often advocate for Quality Adjusted Life Years (QALYs) maximization in resource allocation.
- Current QALY calculations inadequately incorporate broad societal preferences, particularly regarding quality of life.
Purpose of the Study:
- To investigate if the traditional QALY maximization model accurately predicts public responses to healthcare priority setting.
- To explore public preferences in healthcare resource allocation beyond standard QALY metrics.
Main Methods:
- An interview-based survey was conducted with 91 members of the general public.
- Participants' choices in hypothetical healthcare priority settings were analyzed.
- The study assessed consistency with QALY maximization objectives.
Main Results:
- Public responses frequently deviated from QALY maximization predictions.
- Quality of life was a primary influence on public decision-making.
- Limited public support was found for interventions offering prognostic gains but resulting in poor health states.
Conclusions:
- The standard QALY maximization model may not fully capture public preferences for healthcare resource allocation.
- Societal values, particularly concerning quality of life, should be more integrated into priority-setting frameworks.
- Public engagement in priority setting is complex and not solely driven by clinical data.
