Evidence-based medicine (EBM) has experienced numerous advances since its inception over 2 decades ago. Yet a persistent gulf remains between how medicine is actually practiced and the goal of providing care based on best available research evidence integrated with patient perspective and clinical expertise. A primary source of challenge for EBM is induced by inefficiencies in the generation, synthesis, and translation of evidence. During the 8th International Conference for Evidence-based Healthcare Teachers and Developers, GIMBE Foundation presented an innovative approach by defining an ecosystem of evidence. Based on the features of a natural ecosystem, the ecosystem of evidence is influenced by living organisms: stakeholders replete with competition and collaboration among and between them, as well as their conflicts of interest; the environment: social, cultural, economic, and/or political contexts; and nonliving components: scientific evidence, influenced by the rules, standards, and frameworks associated with evidence generation, synthesis, and translation. This article provides an analysis of the strengths and weaknesses of this ecosystem with a focus on nonliving components, specifically evidence generation, synthesis, and translation. Specific suggestions are outlined for building a stable and resilient ecosystem of evidence.
循证医学(EBM)自 20 多年前诞生以来经历了许多发展。然而,医学实践的实际情况与基于最佳现有研究证据并结合患者观点和临床专业知识提供护理的目标之间仍然存在着持久的差距。EBM 的一个主要挑战来源是证据的生成、综合和转化效率低下。在第 8 届国际循证医疗教师和开发者大会上,GIMBE 基金会提出了一种创新方法,通过定义证据生态系统来解决这个问题。基于自然生态系统的特点,证据生态系统受到生物体的影响:利益相关者之间充满竞争与合作,以及他们的利益冲突;环境:社会、文化、经济和/或政治背景;非生物成分:科学证据,受与证据生成、综合和转化相关的规则、标准和框架的影响。本文对该生态系统的优势和劣势进行了分析,重点是非生物成分,特别是证据的生成、综合和转化。为建立一个稳定和有弹性的证据生态系统,本文提出了具体建议。
