Policy applications of health expectancy

Empirical estimates of trends in health expectancy throughout the nations of the developed world provide conflicting evidence on the debate whether increasing life expectancy is accompanied by a compression or expansion of morbidity and disability. Complicating this issue is the fact that various methods are available for calculating health expectancy, each requiring a unique and often difficult to obtain source of data. It is suggested here that to reliably communicate the policy relevance of the measure of health expectancy it is necessary for countries such as the United Kingdom to make a long-term commitment to developing longitudinal databases that permit the most reliable estimates of trends in the health status of the population.
