Quality Adjusted Life Year (QALY)

A method for comparing health outcomes, which assigns each year of life a weight, from 1 (perfect health) to 0 (judged equivalent to death), dependent on the individual’s health-related quality of life during that year. A total score of years multiplied by weight can then be compared across different interventions. There is disagreement about the best methods for measuring health-related quality of life.
