If there is no value set for my country, I am supposed to use an existing value set for a similar population. How do I assess whether a population is sufficiently similar?

Please see this webpage on choosing a value set. Many factors determine if another country’s value set can be used, such as geography, religion, language, level of development of the country, healthcare system etc. In addition, local HTA guidelines may come into play. Therefore, it is advised to contact local regulatory authorities about their requirements.

Please note, if a standard EQ-5D-5L value set is not available for your country, then an interim “crosswalk” value set can be used, if available. A crosswalk value set is one that has been created for the EQ-5D-3L and then adapted to fit the EQ-5D-5L descriptive system. More information on the crosswalk can be found here.
