EQ-5D Value Sets

Ugandan and Ethiopian tariffs produced different absolute scores and dimension weights. International health economic studies should use country-specific value sets where possible. Utility scores depend on the value set because value sets encode population preferences about health dimensions. The Ugandan tariff produced a larger estimated utility loss because pain and discomfort were prominent and heavily weighted. Tanzania did not have its own EQ-5D value set, so the study used Uganda for the base case and Ethiopia for sensitivity analysis. The absence of a Tanzanian EQ-5D value set was a key limitation of the study.
