How can EQ-5D be used
EQ-5D can be used in clinical trials, in population health surveys, in routine outcome measurement and many other types of studies where a generic measure of health status is useful.
In clinical trials: Treatment effects can be assessed by measuring health status with EQ-5D at different points in time, e.g. before and after treatment, and then investigating the gains (or losses) in reported health status.
In population health surveys: Data collected with EQ-5D can be used to assess and compare health status between groups of patients, between patients and the general population, or between the general populations of different countries.
Routine outcome measurement: Longitudinal data collected with EQ-5D can be used at the individual level to monitor a patient’s health status over time, at the institutional (e.g. hospital) level to monitor the institute’s performance as a health care provider, or at the national level to monitor the population’s health over time.
Instructions on how to fill in EQ-5D and suggestions on how to report results obtained with EQ-5D can be found in the User Guides.
