Dictionary meaning
a summary measure of population health that combines in a single metric the number of years of life lost due to premature death and the number of years lived in states of less than full health, weighted by the severity of disability; one DALY represents one year of healthy life lost; DALYs enable comparison of the health impact of conditions with very different clinical profiles — a condition that causes early death contributes years of life lost, while a chronic disabling condition that rarely causes death contributes years lived with disability; the metric is central to the Global Burden of Disease project and to cost-effectiveness analyses used in health policy decisions
