循证实践和临床有效性的概念依赖于最新的、准确的、高质量的和相关的信息。虽然这些信息可以从多种来源获得，但是像MEDLINE这样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、有效的方法来获取最新信息。从数据库中搜索信息时，常见的问题包括丢失重要的相关论文或检索过多的信息。因此，需要有效的搜索策略来检索可管理数量的相关信息。本文提出了一系列可用于高效定位MEDLINE信息的策略。
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.
