Valuing health‐related quality of life : an EQ‐5D‐5L value set for Morocco

Purpose There is a growing interest in Health Technology Assessment (HTA) in Morocco. A national EQ-5D-5L value set would allow for the computation of Quality Adjusted Life Years (QALYs) in economic evaluations of healthcare interventions to support decision-making. This study aimed to develop a Moroccan EQ-5D-5L value set based on data from a representative sample of the Moroccan adult general population. Methods A Moroccan representative sample of adults was recruited using stratified quota sampling based on gender, age category, and place of residence. Data were collected between November 2022 and December 2023 using the international EuroQol valuation protocol, EQ-VT version 2.6.1. This protocol includes two elicitation techniques: the composite time trade-off (cTTO) and the discrete choice experiment (DCE). cTTO and DCE data were modeled using a heteroskedastic Tobit model and a conditional logit model, respectively. In addition, these models were combined using a hybrid model. Results A total of 976 respondents were included in the final analysis. The hybrid heteroskedastic model was considered the preferred model. The predicted utility values ranged from −1.492 for the worst health state (55555) to 1 for full health (11111), where the two mildest impaired states (11211 and 21111) had a utility value of 0.979. Pain/discomfort had the largest effect on health utility values, followed by anxiety/depression, mobility, self-care and usual activities. Conclusion Morocco is the third country in the Middle East and North Africa (MENA) region with an EQ-5D-5L value set. This study supports the use of EQ-5D-5L data for healthcare decision-making in the Moroccan context.
