OP94 Online Elicitation Of Personal Utility Functions (OPUF): A New Tool For Eliciting EQ-5D-5L Value Sets On The Societal-, Group-, Subgroup-, And Individual-Level

Introduction The ‘Online elicitation of Personal Utility Functions’ (OPUF) is a new method for valuing health states. It based on compositional preference techniques. In contrast to established, decompositional techniques, such as time trade-off or discrete choice experiment (DCE), the OPUF approach does not require hundreds thousands respondents, but allows estimating utility functions small (patient) groups and even individual level. objective this study was generate compare EQ-5D-5L value sets societal-, group-, subgroup-, individual-level. Methods A demonstration version Tool available at: https://eq5d5l.me. broadly consists three valuation steps: dimension weighting, level rating, anchoring. Responses were combined construct personal functions. Every respondent also completed conventional DCEs. Preferences aggregated across individuals estimate societal various group-level We then assessed heterogeneity preferences between using descriptive statistics k-means cluster analysis. Results representative sample (n = 1,000) United Kingdom (UK) population recruited through prolific online platform. On average, it took participants about 7 minutes complete survey. Data 874 respondents included in For each respondent, we constructed set. derived predicted respondents’ choices DCE with an accuracy 78 percent. level, values states ranged from -0.376 1. Health state varied greatly groups. This largely due differences anchoring, while there near consensus relative importance five EQ-5D dimensions Demographic characteristics explained only proportion variability. Conclusions Using approach, able set UK, examine underlying unprecedented detail.
