1. Cost-Effectiveness Analysis (CEA): QALYs are often used in CEA to compare the cost per QALY gained for different interventions. This helps in identifying treatments that provide the best value for money. 2. Health Technology Assessment (HTA): Organizations like the National Institute for Health and Care Excellence (NICE) use QALYs to assess the benefits of new medical technologies and drugs. 3. Burden of Disease Studies: QALYs help in measuring the overall burden of diseases, taking into account both premature death and reduced quality of life.
