A year of life lived in perfect health is worth 1 QALY (1 year of life × 1 Utility value)

The quality-adjusted life year or 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 for money of medical interventions.[1] One QALY equates to one year in perfect health.
