How To Conduct A Systematic Review: The Search

The Search

The research team will:

  • Decide whether to search Medline through PubMed or Embase
  • Select which journal article databases are relevant to their research topic
  • Identify types of grey literature that are relevant to their topic
  • Decide if hand searching will improve their search strategy and what sources are appropriate for this method

Note: the search should be repeated before the final analysis in order to capture literature that was published since the initial search. This helps to create an up-to-date systematic review that includes the most recent literature available.

Databases To Search

Databases index journals and no single database includes all journals in a particular subject area. PubMed is a common starting point for health sciences reviews. You should use other database in addition to PubMed. Some of the more common databases are listed below.  Check the A-Z list of databases for a complete list.

Hand Searching

Hand searching refers to reading through specific journal table of contents and selecting articles relevant to the research topic. This is an additional search strategy that can be used to capture literature that may have been missed by searching a journal article database.
