All details of the search should be documented so that: ◦ It is transparent and reproducible ◦ It can be evaluated
Describe in detail all searches, including: ◦ Bibliographic databases ◦ Internet/grey literature ◦ Hand-searching ◦ Contact with experts Good practice to document the search whilst doing it rather than retrospectively!
Database or resource searched Database service provider or URL Date of search Date span of search The search strategy itself, in full Number of records identified
Database or resource e.g. Medline, PubMed, CEA Registry etc The database service provider e.g. Ovid, EBSCO, ISI Web of knowledge etc The website/organisation providing the resource e.g.
Date of the search Date of the database or resource (inception to latest update) Not always easy to find the latest update date – might have to do a bit further investigation
Ideally, reproduce the search strategy directly from the search interface (If using PubMed each search listed in Advanced area as you search, copy & paste! ) May prefer to edit strategies for consistency and/or readability May want to annotate and provide key to symbols/commands used
Flow charts e.g. PRISMA flow diagram, template at: Tables Or simply in the search strategy itself (As you search in PubMed number of ‘Items found’ are listed in Advanced area)
Should not simply be a technical exercise – it is an opportunity to justify decisions made when developing the search strategy Why certain limits were introduced Why methodological filters were not used Why particular databases were not searched How search terms were derived Describe the conceptual breakdown of the search
Always write up in full (record absolutely everything) while undertaking the searches It is often not possible to include everything in the main body of the final report, and certainly not in a journal article But should be able to include details in appendices or at least be able to refer reader to the full search strategies
