Where Next for EQ-5D-5L National Value Sets and the EQ-VT Protocol?

Abstract

AbstractThe purpose of this chapter is to reflect on the future of EQ-5D-5L valuation studies, going beyond the value sets summarised in this book. This includes a number of linked themes. First, the EQ-5D-5L valuation research programme has allowed the continued evolution of methods, as methodological studies have demonstrated that aspects of the EQ-VT protocol could be strengthened or improved. This chapter describes some of the key candidates for future refinement of the methods for valuing EQ-5D-5L. Second, while the standardisation of valuation methodology is important, it is anticipated that many countries may require a less resource-intensive, but still rigorous version of the valuation protocol. This chapter outlines the progress towards developing a ‘lite’ version of the EQ-VT protocol, and considers the future possibility of valuation protocols based exclusively on discrete choice experiments, with accompanying strengths and weaknesses. Finally, the ‘shelf-life’ of value sets is considered, along with how demographic and other societal changes may manifest in how people value health, and the implications of that for the need to update EQ-5D-5L value sets.
