Quality Adjusted Life Year
A measure of disease burden that combines length of life and quality of life into a single metric.
Definition
A QALY is a generic measure of disease burden that accounts for both the quantity and quality of life generated by a healthcare intervention. One QALY equates to one year in perfect health. A year in a health state with a utility weight of 0.5 is worth 0.5 QALYs. QALYs are the standard outcome measure used in cost-effectiveness analysis by health technology assessment bodies such as NICE.
