Medicine, Nursing and Health Sciences: Search filters

Search filters

What are search filters?

A search filter is a defined search strategy designed to find certain types of articles in a particular database. They are usually validated for recall and precision. There are two types of search filters. Methodological filters target certain study designs, such as randomised controlled trials. Subject search filters target a particular subject field.

Paramedic search filters for Ovid Medline and PubMed

Sensitive filter  for OVID Medline is optimal for use by researchers in order to capture all relevant papers.

Specificity filter for OVID Medline is optimal for use by clinicians and students who are requiring a strategy that may not identify all papers however will retrieve the most relevant papers.

Sensitive filter for PubMed (note: select Best Match in the new PubMed when viewing the results)

Clicking on these links will connect to the database indicated and run the chosen filter. You can then combine your other concepts with the results of the filter by using AND.
