EQ-5D-5L | Valuation | Crosswalk Index Value Calculator
“In the NICE position statement on the use of the English EQ-5D-5L valuation set, published in August 2017, reference is made to the van Hout et al. (2012) mapping function, which is described and made available below.“
The EuroQol Group coordinated a study that administered both the 3-level and 5-level versions of the EQ-5D, in order to develop a “crosswalk” between the EQ-5D-3L value sets and the new EQ-5D-5L descriptive system, resulting in crosswalk value sets for the EQ-5D-5L. A total of 3691 respondents completed both the 3L and 5L across 6 countries: Denmark, England, Italy, the Netherlands, Poland and Scotland. Different subgroups were targeted, and in most countries, a screening protocol was implemented to ensure that a broad spectrum of levels of health would be captured across the dimensions of EQ-5D for both the 5L and 3L descriptive systems.
Crosswalk value sets for the EQ-5D-5L are available for the following countries: Denmark, France, Germany, Japan, the Netherlands, Spain, Thailand, UK, US and Zimbabwe. A scientific publication by Van Hout et al. (2012) describing the mapping methodology behind the study in detail is published in Value In Health Journal. A more detailed description of the crosswalk model and methodology, and the actual index values can be downloaded below:
A tool “EQ-5D-5L Crosswalk Index Value Calculator” calculates the crosswalk index values for the EQ-5D-5L dimension scores and can be downloaded below:
