The disability-adjusted life year (DALY) is an increasingly used population health metric (Murray et al. 2013; Devleesschauwer et al. 2014). DALYs are healthy life years lost, calculated by adding the adjusted number of years lived with disability (YLDs) and the number of years of life lost due to premature mortality (YLLs):
$${\text{YLD}} = {\text{Number}}\,{\text{of}}\,{\text{cases}} \times {\text{duration}}\,{\text{till}}\,{\text{remission}}\,{\text{or}}\,{\text{death}} \times {\text{disability}}\,{\text{weight}}$$
(1)
$${\text{YLL}} = {\text{Number}}\,{\text{of}}\,{\text{deaths}} \times {\text{life}}\,{\text{expectancy}}\,{\text{at}}\,{\text{the}}\,{\text{age}}\,{\text{of}}\,{\text{death}}$$
(2)
$${\text{DALY}} = {\text{YLD}} + {\text{YLL}}$$
