Abstract: Objectives Traditional economic evaluations in healthcare focus on efficiency but rarely address how health gains are distributed across populations. This project aims to develop, adapt, and test methodologies that explicitly integrate equity into economic evaluations to support fairer health decision-making in the French context. Methods Two complementary approaches will be operationalized: (1) Equity weighting methods, which will adjust cost-effectiveness metrics using weights reflecting population vulnerability; and (2) Distributional Cost-Effectiveness Analysis (DCEA), which will quantify the redistributive impact of health interventions across socioeconomic groups. These methods will be adapted to the French healthcare system, using both aggregated and individual-level data (e.g., from administrative sources and clinical studies). A series of Algorithms and implementation guides will be developed, and the methodologies will be applied to multiple use cases (diabetes, cancer, depression, hearing loss, care coordination). Results The project will generate enhanced cost-effectiveness estimates that incorporate socioeconomic variables. It is expected that applying these equity-informed methods will, in some cases, significantly shift the conclusions of conventional economic evaluations: interventions previously deemed efficient may appear less favorable when considering their distributive impact—and vice versa. The project will also produce practical tools (e.g., equity weighting tables, code libraries, methodological guides) for routine use. These results will help identify interventions most likely to reduce health inequalities while maintaining acceptable levels of efficiency. Conclusions The INEES project will deliver actionable, equity-sensitive economic evaluation tools tailored to the French context. By explicitly integrating both efficiency and equity, this project will contribute to the development of more socially responsive decision-making frameworks, with potential to inform HTA practices, resource allocation, and health policy at the national level.
