Quality Adjusted Life Years (QALY) is another measure used in public health and health economics. While DALY focuses on the burden of disease, QALY is used to assess the value of medical interventions. QALY combines the quantity and quality of life lived, with one QALY equating to one year in perfect health. The main difference lies in their application: DALY measures the burden of disease, and QALY assesses the effectiveness of interventions.
