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 cause-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.
基于消除病因期望寿命（CELE）、健康调整期望寿命（HALE）和伤残调整生命年（DALY）的概念与方法整合，本研究开发了一种名为排除病因健康调整期望寿命（CEHALE）的新指标，以评估单一疾病对健康的影响（包括胎儿期和非胎儿期）。为了纳入过早死亡和在世者健康问题的影响，引入了假设死亡的概念来计算CEHALE。本研究中开发的排除病因健康调整期望寿命不仅在概念上易于理解，而且有理论支持，不受年龄结构影响，更适合用于不同疾病和不同人群之间的比较。此外，新指标易于计算。因此，CEHALE应该是评估疾病对人群健康影响的理想指标。
