The periodic calculation of healthy life expectancies permits the evaluation of the impact of new health policies at a given moment, as well as the assessment of trends under changing health conditions. In spite of their apparent simplicity, the results obtained will have to be interpreted by experts. Useful reference values can be provided by international comparisons. However, several choices remain to be made, such as (i) the types of morbidity and disability data to be associated with mortality data; (ii) the multiple indicators available; (iii) the type of observations to be recorded, i.e., "abilities" or "performances"; (iv) whether or not the recovery of lost functions should be considered; (v) the mode of computation, i.e., life expectancy before the first morbid event or global healthy life expectancy; and (vi) the determination of thresholds based on either relative or absolute criteria.
定期计算健康预期寿命有助于评估特定时刻新卫生政策的影响，以及评估健康状况变化时的趋势。尽管计算结果看似简单，但仍需专家进行解读。国际比较可提供有用的参考值。然而，仍有几个问题有待抉择，例如：（i）与死亡率数据相关联的发病率和残疾数据类型；（ii）可用的多个指标；（iii）要记录的观察类型，即“能力”或“表现”；（iv）是否应考虑丧失功能的恢复情况；（v）计算方式，即首次发病事件前的预期寿命或总体健康预期寿命；以及（vi）基于相对或绝对标准确定阈值。
