越来越多的卫生保健专业人员需要根据现有的最佳证据做出临床决策。循证医学(EBM)是一种解决临床问题的系统方法，它允许将最好的可用研究证据与临床专业知识和患者价值相结合。本文阐述了循证医学的概念，介绍了循证医学的五个步骤：提出可回答的临床问题；寻找证据；批判性评价；证据的适用性；绩效评价。随后的文章将集中于随机对照试验、系统评价和荟萃分析的原则和关键评估，并使用现实生活中的临床场景提供五步循证医学模型的实际演示。
Health care professionals are increasingly required to base clinical decisions on the best available evidence. Evidence based medicine (EBM) is a systematic approach to clinical problem solving which allows the integration of the best available research evidence with clinical expertise and patient values. This paper explains the concept of EBM and introduces the five step EBM model: formulation of answerable clinical questions; searching for evidence; critical appraisal; applicability of evidence; evaluation of performance. Subsequent articles will focus on the principles and critical appraisal of randomised controlled trials, systematic reviews, and meta-analyses, and provide a practical demonstration of the five step EBM model using a real life clinical scenario.
