Generalized Cost-Effectiveness Analysis (GCEA / WHO-CHOICE)
Generalized Cost-Effectiveness Analysis (GCEA) helps countries decide which health interventions offer the best value for money by comparing costs and health outcomes across a wide range of diseases and interventions. Developed through the WHO-CHOICE project, it provides cost-effectiveness estimates that can be adapted to specific country contexts.
At a glance
Use when
Setting national or regional health priorities, allocating limited health budgets efficiently, guiding investment in new or underfunded interventions, supporting health policy decisions with economic evidence.
Avoid when
Highly context-specific interventions with poor transferability, when local data are too weak to adapt models, or when political and social factors dominate decision-making beyond efficiency considerations.
Inputs
Intervention costs (unit prices, quantities), epidemiological data, coverage rates, efficacy and adherence estimates, disability weights, demographic data, and health system context parameters.
Outputs
Cost-effectiveness ratios (e.g., cost per DALY averted), rankings of interventions by efficiency, tailored national-level priority lists, and efficiency frontiers.
How it works
GCEA is a form of sector-wide cost-effectiveness analysis that generates sub-regional estimates of intervention costs and health effects (e.g., DALYs averted) for major diseases and risk factors. These estimates are transferable and customizable to national settings by adjusting input costs, coverage, efficacy, and adherence. WHO-CHOICE uses standardized modeling to assess a broad intervention portfolio, enabling comparison across health programs and supporting priority-setting based on efficiency. It also allows integration with equity considerations and other policy goals.

- Assumptions
- Interventions can be meaningfully compared using common metrics like DALYs; scalability and transferability of interventions across settings are feasible with adjustments; health system constraints are accounted for in coverage and delivery assumptions.
- Strengths
- Provides comparable evidence across a wide range of interventions and regions; allows customization to national contexts; supports transparent, evidence-based priority setting; incorporates efficiency and equity considerations.
- Limitations
- Relies on modeling and assumptions that may not reflect local realities; data quality and availability can affect accuracy; may not capture all implementation barriers or social preferences.
