OBJECTIVES: EQ-5D-5L is a widely-used measure of patient-reported health. Its use in economic evaluation requires a 'value set': numerical summaries of how good or bad each health state is. No EQ-5D-5L value sets are currently available in the Middle East. Our study is, to our knowledge, the first to investigate the potential for using standard health state valuation methods in this region. To test the feasibility of eliciting EQ-5D-5L values from a sample of the UAE general public using the EuroQol Group’s standardised protocol; and to investigate any cultural issues relating to the use of the methods amongst Emirati nationals. METHODS: Values were elicited using face-to-face computer-assisted personal interviews, following the standardised protocol for valuing EQ-5D-5L. Adult members of the Emirati general public were recruited in public places Respondents each completed 10 time trade-off (TTO) tasks and seven discrete choice experiment (DCE) tasks. In addition, they answered debriefing questions about their experience of completing the valuation tasks. Descriptive analyses were used to assess the face validity of the data. RESULTS: Two-hundred individuals were interviewed in December 2013. The face validity of the data appear to be reasonably high, with higher (lower) values elicited for mild (severe) health states. In the TTO tasks, mean values ranged from 0.812 for the mildest state (21111) to 0.194 for the worst state (55555). Health states were rarely valued as being worse than dead (6.1% of all observations). In a rationality check included in the DCE tasks, 99.5% of the respondents chose the dominant state (55221) over the dominated state (55554). CONCLUSIONS: Analysis is currently underway - final conclusions will be available by the time of the AP ISPOR meeting. We will discuss whether the standard methods are suitable for use in the UAE (and other countries with predominantly Muslim populations), or if some adaption of the methods is required.
