A QALY score of 1 represents what state?

Explanation:
Quality-adjusted life years (QALYs) combine how long you live with how good your health is during that time. Each year is weighted by a health-state utility between 0 and 1, where 0 means death and 1 means perfect health. So a QALY score of 1 means one year lived in perfect health—the best possible health state. If health isn’t perfect, the utility falls below 1, giving a QALY less than 1 for that year. Death is 0 QALYs, and “unknown” isn’t a defined state in this framework.
