一个新的文献评价系统——GRADE评价系统

A New Literature Evaluation System——GRADE System

循证医学要求对现有临床证据进行综合评价以指导临床实践。临床文献的正确评价不但有利于临床指南的制定,也有利于临床决策。目前存在的诸多文献评价系统虽然方便了临床文献的评价,但对于文献评价过程中有争议证据的评价却没有合适的解决方法。本文介绍一种新的文献评价系统,将该系统的文献评价方式及有争议证据的评价方式进行介绍,为我国临床工作人员和政策制定者开展文献评价工作提供参考。

Evidence-based medicine is an approach to medical practice intended to optimize decision-making by evaluating currently available evidence.Proper evaluation of clinical literature could not only facilitate development of clinical guidelines,but also help make good decision of medical practice.Although current literature-evaluating systems improve the progress of literature evaluation,but it is still unsolvable to correctly resolve the uncertainty between different opinions.This article is to introduce a new literature-evaluating system by elaborating how it grades literature and how it resolves the dispute between different opinions,which might help clinical practitioners and policy makers make better decisions.
