What Are Cost-Effectiveness and Cost-Benefit Analyses?
Cost-effectiveness analysis (CEA) and cost-benefit analysis (CBA) are two critical tools in epidemiology. CEA compares the relative costs and outcomes of different interventions, often expressed as cost per QALY gained. For example, CEA might compare the cost-effectiveness of two different vaccination programs. CBA, on the other hand, evaluates the financial benefits of an intervention relative to its costs, often used to justify public health expenditures.
