The concepts of evidence-based practice and clinical effectiveness are reliant on up to date, accurate, high quality, and relevant information. Although this information can be obtained from a range of sources, computerised databases such as MEDLINE offer a fast, effective means of bringing up to date information to clinicians, as well as health service and information professionals. Common problems when searching for information from databases include missing important relevant papers or retrieving too much information. Effective search strategies are therefore necessary to retrieve a manageable amount of relevant information. This paper presents a range of strategies which can be used to locate information on MEDLINE efficiently and effectively.
循证医学实践和临床疗效的概念依赖于最新、准确、高质量且相关的信息。尽管这些信息可从多种来源获取，但诸如MEDLINE之类的计算机化数据库为临床医生以及卫生服务和信息专业人员提供了一种快速、有效的获取最新信息的方式。从数据库中搜索信息时常见的问题包括遗漏重要的相关论文或检索到过多信息。因此，需要有效的搜索策略来检索数量可控的相关信息。本文介绍了一系列可用于高效且有效地在MEDLINE上查找信息的策略。
