摘要 卫生体系的差异往往使得在某种环境下适用的卫生政策或规划不适用于其他情况,或这种差异使相同的卫生政策或规划在不同环境下起作用的方式不同,甚至使其效果大相径庭。因此,决策者及其支持者所面临的最大挑战是需弄清支持某一决策的研究证据是否适用于他们所处的环境。系统评价通过总结各种背景下的研究证据而使这一问题迎刃而解。但许多系统评价并未对描述原始研究的实施背景。本文建议用下面几个问题来指导决策者评价系统评价结果在特定环境下的适用性:①系统评价纳入研究的实施背景是否相同或研究结果是否能在不同环境下或不同时期内保持一致性?②有可能明显改变决策的可接受性和可行性的现实条件和制约因素是否存在重要差异?③在卫生系统制度方面是否存在重要差异从而意味着某种决策不能以同样的方式起作用?④基线情况是否存在重要差异以至于产生不同的绝对效应,尽管相对效应是一致的?⑤从决策、实施、监测及评估中还能得到哪些启示?尽管有理由推断某决策在某特定环境下的作用可能不同,但我们几乎总是可以从对各种可能的决策方案及其实施、监测、评估方法的系统评价中获得一些启示。
