3.6 Years of life lost due to AMR

Years of life lost (YLL) is a measure of premature mortality. It is a calculation of the number of years a person would have lived had they not died prematurely from a resistant infection.

For example, consider a situation in which ten neonates died due to sepsis caused by 3GCR bacteria in District X, which has a standard life expectancy of 70 years. Each neonate is assumed to have lost 70 years of life due to premature death so for ten neonates the total YLL would be 10 × 70 or 700 life years.

This measurement is an important metric in the calculation of the economic burden of AMR, which will be discussed later in this course.
