Years of potential life lost
From Wikipedia, the free encyclopedia
Years of potential life lost (YPLL) or potential years of life lost (PYLL) is an estimate of the average years a person would have lived if they had not died prematurely.[1] It is, therefore, a measure of premature mortality. As an alternative to death rates, it is a method that gives more weight to deaths that occur among younger people. An alternative is to consider the effects of both disability and premature death using disability adjusted life years.
This article may be confusing or unclear to readers. In particular, Examples, instead of using the YPLL as defined, show the value YPLL × 100000 or use different undefined terms such as 'Person Years Lost' or YLL. (May 2016) |
