As evidence-based practice has become an important issue in healthcare settings, the educational needs for knowledge and skills for the generation and utilization of healthcare evidence are increasing. Systematic review (SR), a way of evidence generation, is a synthesis of primary scientific evidence, which summarizes the best evidence on a specific clinical question using a transparent, a priori protocol driven approach. SR methodology requires a critical appraisal of primary studies, data extraction in a reliable and repeatable way, and examination for validity of the results. SRs are considered hierarchically as the highest form of evidence as they are a systematic search, identification, and summarization of the available evidence to answer a focused clinical question with particular attention to the methodological quality of studies or the credibility of opinion and text. The purpose of this paper is to introduce an overview of the fundamental knowledge, principals and processes in SR. The focus of this paper is on SR especially for the synthesis of quantitative data from primary research studies that examines the effectiveness of healthcare interventions. To activate evidence-based nursing care in various healthcare settings, the best and available scientific evidence are essential components. This paper will include some examples to promote understandings.
随着循证实践已成为医疗保健环境中的一个重要问题，对医疗保健证据的产生和利用所需的知识和技能的教育需求正在增加。系统评价（SR）作为一种证据产生方式，是对原始科学证据的综合，它使用一种透明的、预先设定的方案驱动方法来总结关于特定临床问题的最佳证据。SR方法需要对原始研究进行批判性评价，以可靠且可重复的方式提取数据，并检验结果的有效性。SR被视为最高级别的证据，因为它们是对现有证据进行系统的搜索、识别和总结，以回答一个重点突出的临床问题，尤其关注研究的方法学质量或观点及文本的可信度。本文的目的是介绍SR的基础知识、原则和过程的概述。本文的重点是SR，特别是用于综合来自检验医疗保健干预效果的原始研究的定量数据。为了在各种医疗保健环境中激活循证护理，最佳且可得的科学证据是必不可少的组成部分。本文将包括一些示例以促进理解。
