QALY
Version 1.0.0 · Updated 2026-07-30
CORE DEFINITION
Quality-Adjusted Life Year. 1 QALY = one year in perfect health. Living in a vegetative state for a year might be valued at only 0.1 QALY.
SCAFFOLDING EFFECT
Reduce cognitive load
Life quality decisions. Do not just pursue 'being alive' (longevity); calculate QALY. If a decision gives you 5 more years but with extreme suffering (low QALY), it may be worse than a decision that gives you 3 happy years.
Anchor fast decisions
The quality-adjusted life year (QALY) combines survival time and quality of life into a single metric: 1 QALY equals one year in perfect health. It is used to compare the cost-effectiveness of different medical interventions and to aid resource allocation.
