A model for clinical decision making in which estimates of impairment or disability are factored into calculation of life expectancy. It is also a method of adjusting life expectancy to allow for reduced quality of life caused by chronic conditions. Many chronic conditions shorten life on average by predictable amounts. These expected amounts can be estimated from available sources, such as hospital discharge data and health survey data, and used to produce a QALE for individuals or subsets of the population. At the individual level, the QALE is based on clinical judgment and subjective opinions of patients about their quality of life, preferably arrived at by consensus between clinicians and patients.
