Mapping between EQ-5D-5L and EQ-5D-3L
This is a project was part-funded by The Department of Health’s Policy Research Unit in Economic Methods of Evaluation of Health and Social Care Interventions (EEPRU). The aim of the project was to develop a reference case mapping between 3L and 5L, suitable for mapping in either direction.
Further details can be found on the EEPRU project page, estimating the relationship between EQ-5D-5L and EQ-5D-3L.
DSU work
In order for analysts to be able to easily implement the results from the mapping model, Stata, Excel and R commands have been developed. These are available below, along with instructions on how to use them.
When using these commands, please cite the associated Hernández Alava, M., Pudney, S. & Wailoo, A. Estimating the Relationship Between EQ-5D-5L and EQ-5D-3L: Results from a UK Population Study. PharmacoEconomics 41, 199–207 (2023). https://doi.org/10.1007/s40273-022-01218-7.
The Stata eq5dmap command has been updated and can now be installed from within Stata by typing search eq5dmap and following the on-screen instructions.
