PURPOSE: Although several EQ-5D-5L valuation studies have been conducted in the Asian region, including China, Hong Kong, Indonesia, Japan, Malaysia, Singapore, South Korea, Taiwan, Thailand, and Vietnam, published value sets differ across health jurisdictions. Accounting for these variations is complicated by several factors that include underlying differences in healthcare governance, finance and organization. Variability attributable to the valuation methods used is imperfectly understood. The use of EQ-VT (a standardized method for eliciting health state valuations) has helped to improve data quality; differences in data analysis strategies and the details of modelling methods may nevertheless still contribute to variations between value sets.

This workshop is intended to improve our understanding of how EQ-5D values differs across the Asian region and to explore their implications for future valuation studies. Findings based on the analysis of primary data collected in Asian 5L valuation studies will form the basis of the workshop. PIs of 5L valuation studies whose data have been shared with the workshop leaders, will be invited to participate.

DESCRIPTION: The workshop will begin with an introduction to the current state of play in EQ-5D-5L valuation in the Asian region. Key elements of the EQ-VT procedure will be described, for example the use of the lead-time form of TTO to value states worse than dead. The robustness of data across valuation studies will demonstrated using pre-defined criteria. Internal consistency between DCE and TTO methods will be compared. A panel-led discussion will explore potential explanations for the observed differences in regional EQ-5D-5L value sets. The implications of this variation in values for health policy will be exemplified. Recommendations for the future conduct of valuation studies will be proposed

The workshop will conclude with an interactive Q&A session during which audience will have the opportunity to discuss with members of the panel and valuation study PIs.
