OBJECTIVES: EQ-5D is the most widely recommended instrument in guidance from health technology assessments bodies. The presence of multiple value sets within some countries highlights the need to select the most appropriate one. Since the reviews by Rowen et al (2022) and Poudel et al (2022) the number of published EQ-5D-5L value sets has grown substantially. This systematic review updates the evidence base by identifying EQ-5D-5L value sets and comparing their methodologies, valuation techniques, and reporting quality.
METHODS: A systematic literature review was conducted in accordance with PRISMA 2020 guidelines. Searches were performed in PubMed, Scopus, the EuroQol website, and grey literature. Studies since inception published up to 7 May 2025 were included if they reported the development of EQ-5D-5L value sets. Data on valuation methods, modelling strategies, and participant characteristics were extracted. Reporting quality was assessed using the CREATE checklist, with ≥80% indicating good quality.
RESULTS: Of the 5,215 records screened, we identified 51 studies that were used to derive 55 value sets, 46 studies were undertaken with the general population, 5 with patients with specific conditions (e.g., cancer, diabetes). Value sets were derived across all World Bank regions (Europe/Central Asia = 23, East Asia/Pacific/South Asia = 16, Latin America/Caribbean/North Africa = 8, Middle East and North Africa/Sub-Saharan Africa =8). Hybrid valuation (TTO + DCE) was most common (51%), with 87.3% using the EQ-VT standardised valuation protocol. Tobit models were frequently used for TTO data; newer studies applied more sophisticated methods including cross-attribute level effects and Bayesian models. Most studies showed good reporting quality though some could be improved in areas such as model selection transparency, response rates, and scoring algorithm details.
CONCLUSIONS: The review provides an important overview of the current state of valuation studies for the EQ-5D-5L, it shows good geographical coverage, methodological rigor and recency of the valuation evidence base.
