This document discusses different types of economic evaluation used for decision making in health care: Cost-effectiveness analysis compares the costs and effects of different interventions to achieve a health objective. Cost-minimization analysis compares costs of programs that achieve identical outcomes. Cost-utility analysis considers both quality and quantity of life by using quality-adjusted life years, allowing comparison across health programs. Cost-benefit analysis values both costs and benefits in monetary terms to directly compare options through a benefit-cost ratio. Economic evaluations are important tools for assessing the efficiency and feasibility of health interventions and identifying relevant alternatives systematically.
