  1. Quality-adjusted life year

    The quality-adjusted life year or quality-adjusted life-year is a generic measure of disease burden, including both the quality and the quantity of life lived. It is used in assessing the value for money of a medical intervention. One QALY equates to one year in perfect health. If an individual's health is below this maximum, QALYs are accrued at a rate of less than 1 per year. To be dead is associated with 0 QALYs, and in some circumstances it is possible to accrue negative QALYs to reflect health states deemed 'worse than dead'.
