Sullivan's index also known as Disability Free Life Expectancy (DFLE) is a method to compute life expectancy free of disability. It is calculated by formula:
Life expectancy
duration of disability
Health expectancy calculated by Sullivan’s method is the number of remaining years, at a particular age, that an individual can expect to live in a healthy state. It is computed by subtracting the probable duration of bed
disability
Disability is the experience of any condition that makes it more difficult for a person to do certain activities or have equitable access within a given society. Disabilities may be cognitive, developmental, intellectual, mental, physical, ...
and inability to perform major activities from the life expectancy. The data for calculation is obtained from population surveys and period life table. The Sullivan's index collects
mortality and disability data separately, and this data is almost often readily available. The Sullivan health expectancy reflects the current health of a real population adjusted for mortality levels and independent of age structure.
