Video - DALY and QALY

The Disability-Adjusted Life Year (DALY) and Quality-Adjusted Life Year (QALY) are measures of population health used to quantify the burden of disease and injury. A DALY is a measure of lost healthy life years, while a QALY is a measure of how many years of life are lived in good health. Both measures incorporate the severity and duration of illness or injury and the age at which it occurs. They can be used to compare different diseases or injuries, or to compare the burden of disease between different populations.
