去病因健康调整期望寿命——一个新的疾病负担评价指标

Cause-excluded health adjusted life expectancy：a new indicator in measuring the burden of diseases

利用去死因期望寿命、健康调整期望寿命、失能调整寿命年的原理和计算方法构建了一个全新的疾病负担评价指标——去病因健康调整期望寿命。去病因健康调整期望寿命通过虚拟死亡人数的概念将疾病导致的伤残和死亡结合到一起，从而解决了健康调整期望寿命难于应用于单个疾病的问题。去病因健康调整期望寿命概念上容易理解，在理论上有依据，计算方法上简单可行，不受评价人口的年龄构成影响，更有利于不同疾病、不同人群间疾病负担的比较。

Based on the integration of concept and methods of cause-eliminated life expectancy （CELE）, health-adjusted life expectancy （HALE） and disability-adjusted life year （DALY）, a new index named canse-excluded health adjusted life expectancy （CEHALE） was developed in this study to evaluate the health impact（both fetal and non-fetal） of single disease. In order to include the impact of both premature death and health problems among those who are alive, the concept of suppositional death was introduced to calculate CEHALE. Cause-excluded health adjusted life expectancy developed in this study, should be not only easy to understand in concept, but also has theoretical support and be not affected by age structure, and be more suitable to use in comparison among different diseases and different population. Moreover, the new index is easy to calculate. So, CEHALE should be an ideal index to evaluate the impact of disease to population health.
