A QALY is best described as which type of measure?

Explanation:
A QALY is a preference-based measure of health utility that combines how long you live with how good your health is during that time. The quality part is derived from people's preferences for different health states, typically scaled from 0 (death) to 1 (perfect health), with possible values below 0 for states considered worse than death. This means each year of life is weighted by the quality of that year, so a total QALY reflects both duration and quality. Because of this, QALYs are used in cost-utility analyses to compare treatments by cost per QALY gained, rather than just counting years lived, costs, or patient satisfaction.
