Introduction[edit | edit source]
Health-Adjusted Life Years are a measurement of the health of a population, typically used in estimates of the burden of disease.
HALYs are used to measure the combined effects of mortality and morbidity in populations; they permit comparisons between illnesses or interventions as well as between populations[1]
They are commonly used to compare the cost-effectiveness of different health interventions.
Calculation of HALY[edit | edit source]
The two most common ways of measuring HALYs are:
- Disability-Adjusted Life Years (DALYs)
- Quality-Adjusted Life Years (QALYs)
Function/Uses of HALYs[edit | edit source]
HALYs are based on the latest available epidemiological data, and the accuracy & usefulness of the HALY measurement depends on the completeness & accuracy of the data used.
Data can be taken from a variety of sources, including: census & national surveillance data; hospital records; surveys (eg. road safety surveys, or health surveys); police records; mortuary records; death certificate information.
Ideally the data should all be recent, locally derived and disaggregated by age and sex.
