Finding current evidence: search strategies and common databases.

With more than 100 orthopaedic, sports medicine, or hand surgery journals indexed in MEDLINE, it is no longer possible to keep abreast of developments in orthopaedic surgery by reading a few journals each month. Electronic resources are easier to search and more current than most print sources. We provide a practical approach to finding useful information to guide orthopaedic practice. We focus first on where to find the information by providing details about many useful databases and web links. Sources for identifying guidelines, systematic reviews, and randomized controlled trials are identified. The second section discusses how to find the information, from the first stage of formulating a question and identifying the concepts of interest, through to writing a simple strategy. Sources for additional self-directed learning are provided.
