Economic evaluation is a research area that involves assessing the value of healthcare interventions or programs in terms of their costs and outcomes. This evaluation can help decision-makers, such as policymakers or healthcare providers, make informed choices about which interventions to prioritize or invest in. Economic evaluation methods often include cost-effectiveness analysis, cost-benefit analysis, and cost-utility analysis. These methods help determine the most efficient ways to allocate resources in healthcare to maximize health benefits for individuals and society as a whole.
