卫生研究中证据的定义与循证规范

Definition of Evidence and Evidence-based Paradigm in Health Research

近20年随着循证医学的发展及其方法学的不断完善,证据概念和循证原则不仅在医学各领域广泛应用,且逐渐渗透于非医学领域。我们调查了不同组织对卫生研究中证据的定义,结合实际工作提出对证据的新定义:"证据是系统评价后的信息";同时论述循证规范的形成,为其服务于其他学科和行业提供借鉴和参考。

With the rapid development of evidence-based medicine during the past two decades, evidence and evidence-based methods were not only used in the field of health care, but also applied to other non-medical fields. A systematic literature search and a comparative study were conducted to investigate the definition of evidence. We also put forward our own definition of evidence： Evidence is the information from the systematic review process. We also discussed the development of evidence-based paradigm and hope this will act as a reference for other subjects and industries.
