ABSTRACT WITHDRAWN
OBJECTIVES: There is some evidence that the results from one country cannot be transferred to other countries. As discrete choice experiment (DCE) is not affected by the feelings about euthanasia, time preference and interviewer effects that were presented in time trade-off (TTO) method, the exploration of the differences in DCE data could provide more insight on how the preference varies. In this study, we compare the EQ-5D-5L data from the DCE part in 11 Asian regions to understand who health preference in Asia vary. METHODS: From 2012 to 2017, 11 regions completed their EQ-5D-5L valuation studies. In each study, 196 pairs of EQ-5D-5L health states were valued using DCE, with each respondent valued 7 pairs. A main effect conditional logit model was used to estimate the regression coefficients for each study. For comparison, we tested the difference statistically and presented the relative importance of dimensions and severity levels. We also calculated the health state values for each region and explored the difference between regions. RESULTS: Between region comparison showed significant difference in regression coefficients, especially for the severe/extreme levels. By eyeballing the relative weights of five dimensions, there appeared to be some similarities among regions, e.g. mobility is the most weighted dimension for all countries except for Vietnam; the relative importance of severity levels were similar across countries (20% for level 2, 30% for level 3, 65% for level 4). More differences can be observed from the analysis suggesting heterogeneity of health preferences among these regions. CONCLUSIONS: This study confirmed that health preferences differed over regions, even in absence of the extraneous TTO factors. It is therefore justifiable to announce that the difference in EQ-5D-5L value set reflects the genuine difference in cultural notions and that therefore different national values sets have to be used in different countries/regions.
