Key result

Distributional cost-effectiveness analysis quantitatively incorporates equity weights (typically 0.5-3.0 in the US) to weigh trade-offs between health disparities and cost efficiency.

Key Points

To describe the principles and practical role of distributional cost-effectiveness analysis (DCEA) in balancing healthcare efficiency and distributional equity within cardiovascular medicine and health policy.
Characterized the 3-step DCEA framework: defining subgroup disparities, quantifying subgroup-specific health and cost impacts, and applying an equity weight within a social welfare function.
Outlined threshold equity weight evaluation using United States benchmark ranges (0.5 to 3.0) against conventional cost-effectiveness thresholds ($50,000 to $150,000 per quality-adjusted life year [QALY]).
Showed that while conventional cost-effectiveness analysis treats every QALY equally, DCEA assigns nonlinear value favoring health gains and cost savings in worse-off populations based on declining marginal utility.
Highlighted a previous evaluation in sickle cell disease gene therapy ($2.45 million; ICER $176,000/QALY), demonstrating that a threshold equity weight of 0.9 falls within standard US ranges (0.5 to 3.0) to favor adoption.
Identified that selecting an equity weight remains a normative choice that cannot capture non-quantifiable dimensions of health equity such as patient autonomy, non-maleficence, and dignity.

Conventional Cost-Effectiveness Analysis (CEA)

Limitations

Cannot exclude subjectivity and bias in the choice of an equity weight value
Most settings lack empirically estimated values for equity weights for specific health disparities
Does not remove the need for qualitative deliberation when decision-makers confront equity-efficiency trade-offs
Cannot capture non-quantifiable aspects of health equity such as autonomy, non-maleficence, and dignity
Most settings lack empirically estimated values for equity weights for specific health disparities (e.g., disease-based or race/ethnicity-specific)
Does not remove the need for qualitative deliberation when confronting equity-efficiency trade-offs

Implication

Distributional cost-effectiveness analysis provides a quantitative framework for cardiovascular researchers and policymakers to explicitly weigh health equity alongside cost efficiency when evaluating healthcare interventions.

Goshua et al. (2025) conducted an editorial in Cardiovascular health disparities. Distributional Cost-Effectiveness Analysis (DCEA) vs. Conventional Cost-Effectiveness Analysis (CEA) was evaluated. Distributional cost-effectiveness analysis quantitatively incorporates equity weights (typically 0.5-3.0 in the US) to weigh trade-offs between health disparities and cost efficiency.
