EQ-5D-5L | Valuation
A standardized valuation study protocol (called EQ-VT) was developed by the EuroQol Group to create standard value sets for the EQ-5D-5L. This protocol is based on the use of the composite time trade-off (cTTO) valuation technique, supplemented by a discrete choice experiment (DCE). We recommend EQ-5D-5L users to use the standard value sets, as these were produced with the EuroQol Group’s standardised valuation technology EQ-VT.
A list of all currently available standard value sets for the EQ-5D-5L can be found in the table below (Last updated on 26JUL2021).
If a value set for your preferred adult EQ-5D version (5L or 3L) is not available for your country/region but a value set for a different EQ-5D version is available, then a “crosswalk” mapping function can be used to derive utility values. The mapping function links EQ-5D descriptive system responses to the available value set.
EuroQol researchers have developed crosswalk functions to:
- Map EQ-5D-5L descriptive system data to value sets for the EQ-5D-3L (van Hout et al, 2012)
- Map EQ-5D-3L descriptive system data to value sets for the EQ-5D-5L (van Hout et al, 2021).
The Van Hout (2012, 2021) crosswalks are based on international datasets, with mapping between response options, and can therefore be implemented with any EQ-5D value set.
Please note that in the UK, as an interim measure whilst a new UK EQ-5D-5L value set is being developed, a different mapping function is recommended for use in submissions to NICE (see EQ-5D-5L valuation webpage) for more information.
