Quality-adjusted life years (QALYs)

Calculated by adjusting the estimated number of life-years an individual is expected to gain from an intervention for the expected quality of life in those years. The quality of life score will range between 0 for death, to 1 for perfect health, with negative scores being allowed for states considered worse than death.
