Why is it not appropriate to use the adult EQ-5D-3L to calculate the EQ-5D-Y index value?

Until recently, no value sets were available for EQ-5D-Y because research showed that the approach used to value EQ-5D-3L health states for use in adult populations was not appropriate when valuing EQ-5D-Y health states for use in economic evaluations of healthcare interventions for paediatric-age populations. Evidence has showed that health states are valued differently when…

What is the difference between the VAS, TTO and DCE techniques? Can they all be used to generate a quality adjusted life year (QALY) score?

The time trade-off (TTO), visual analogue scale (VAS) and discrete choice experiment (DCE) value sets differ in the technique used to elicit the values for the models. In the TTO task, respondents are asked to imagine they live in a certain suboptimal health state for 10 years and then to specify the amount of time…

How should EQ-5D data (value sets) from multinational clinical trials be used?

Data on EQ-5D health states gathered in the context of a multinational trial may be converted into a single summary index using one of the available EQ-5D-3L value sets. There are different options available to do this using appropriate value sets, however, the choice depends on the context in which researchers or decision makers will…

Why are general population values sets used?

To undertake a utility analysis, you will need to use a value set. Generally speaking, utility analysis requires a value set based on preferences from a general population. The rationale behind this is that the values are supposed to reflect the preferences of local taxpayers and potential receivers of healthcare. The EQ-5D value sets are…
