为医学教育的最佳实践寻找证据是一项复杂的工作。由于几乎没有专门用于医学教育本身的信息来源，人们被迫查阅广泛的、往往是巨大的来源--这些资源要么专门用于医学，要么专门用于教育，这使得医学教育搜索变得更加具有挑战性。本指南全面概述了相关的信息来源和方法(包括书目数据库、灰色文献、手工搜索和互联网)，并说明了何时应查阅它们。说明了构建搜索的过程：识别和组合核心概念，使用布尔代数和搜索语法，限制结果集，并最大限度地利用数据库的受控词汇。这一过程用搜索屏幕上的图片进行了说明，随后是许多旨在加强所涵盖的技能和概念的例子。该指南是从为最佳证据医学教育合作进行的系统搜索中获得的持续经验发展而来的，最后展望了将塑造未来医学教育证据搜索的倡议。
Searching for evidence to inform best practice in medical education is a complex undertaking. With very few information sources dedicated to medical education itself, one is forced to consult a wide range of often enormous sources-and these are dedicated to either medicine or education, making a medical education search all the more challenging. This guide provides a comprehensive overview of relevant information sources and methods ( including bibliographic databases, grey literature, hand searching and the Internet) and describes when they should be consulted. The process of constructing a search is explained: identifying and combining core concepts, using Boolean algebra and search syntax, limiting results sets, and making best use of databases' controlled vocabularies. This process is illustrated with images from search screens and is followed by numerous examples designed to reinforce skills and concepts covered. The guide has been developed from the ongoing experience gained from the systematic searches conducted for the Best Evidence Medical Education Collaboration, and concludes by looking ahead to initiatives that will shape future searching for medical education evidence.
