The quality-adjusted life year (QALY) is a metric used in health economics to assess the value of medical interventions by combining both the quantity and quality of life gained. It provides a standardized way to evaluate the cost-effectiveness of healthcare treatments, policies, and interventions by assigning a weight to each year of life based on health-related quality of life measures.
