Quality-adjusted life year

Demonstration of quality-adjusted life years (QALYs) for two individuals. Individual A (who did not receive an intervention) has fewer QALYs than individual B (who received an intervention). The letters A and B designate the boundary lines, with the QALY for A being only the blue area, the QALY for B being the blue area plus the additional tan area. NB It is possible to experience an improvement in health-related quality of life with age, for example through healthier life choices.

The quality-adjusted life year (QALY) is a generic measure of disease burden, including both the quality and the quantity of life lived.[1][2] It is used in economic evaluation to assess the value of medical interventions.[1] One QALY equates to one year in perfect health.[2] QALY scores range from 1 (perfect health) to 0 (dead).[3] QALYs can be used to inform health insurance coverage determinations, treatment decisions, to evaluate programs, and to set priorities for future programs.[3]

Critics argue that the QALY oversimplifies how actual patients would assess risks and outcomes, and that its use may restrict patients with disabilities from accessing treatment. Proponents of the measure acknowledge that the QALY has some shortcomings, but that its ability to quantify tradeoffs and opportunity costs from the patient and societal perspective make it a critical tool for equitably allocating resources.
