From: Incidence, prevalence, and hybrid approaches to calculating disability-adjusted life years
Incidence DALYs. To calculate I-DALYs for year #2, look for events – color changes – in year #2, and then add up the future stream of ill health connected to those events. A sequela-based measurement (see below) will count only Frank’s two years of disability; a pathology-based measurement will also count his 2+ years of premature mortality, but will not count Carol’s four years of premature mortality (unless her death was unrelated to her disability).
