EQ-5D-5L


The EQ-5D comprises five dimensions of health: mobility, ability to self-care, ability to undertake usual activities, pain and discomfort, and anxiety and depression. The original version of EQ-5D allows respondents to indicate the degree of impairment on each dimension according to three levels (no problems, some problems, extreme problems). This is the EQ-5D-3L. A new version of the instrument, EQ-5D-5L, includes five levels of severity for each dimension (no problems, slight problems, moderate problems, severe problems, and extreme problems).

DSU Reports

This report considers how using 5L instead of 3L affects the results of economic evaluations, using case studies of economic models from NICE’s Technology Appraisals programme.

Comparing the EQ-5D-3L and 5L versions. What are the implications for model-based cost effectiveness estimates?

This report describes and assesses different options for linking evidence (“mapping”) from 3L to 5L and vice versa.

Methods for mapping between the EQ-5D-5L and the 3L for technology appraisal (July 2017)

This report is intended to provide information on how using 5L instead of 3L is likely to affect the results of economic evaluations, and highlight the implications of the findings for NICE.
