Evidence-Based Medicine (EBM) is defined as: "The conscientious, explicit and judicious use of current best evidence in making decisions about the care of individual patients." (Sackett, Straus, Richardson, Rosenberg, & Haynes, 2000).

Searching PubMed and filtering for best evidence can be done by applying categorical limits to your PubMed searches, or by using the pre-formulated filters: Clinical Queries, and Special Queries.

Filter (or apply LIMITS) to your search results to:

• Limit by Popular Study Type
• Restrict results by research methodology ("clinical trial," "meta-analysis," etc.)
• Age group
• Publication date
• Language
• more
• Limit by Study Type using MeSH terms

Preformulated LIMITS have been created to assist you in filtering results:

• PubMed Clinical Queries (see box on right) display citations filtered to a specific clinical study category and scope. (Pubmed equivalents)

• PubMed Special Queries provide preformulated interfaces for:

• Health Services Research (HSR) filters: A search interface to find PubMed citations relating to health care quality or to health care costs (Pubmed equivalents)
• Healthy People 2020: Structured Evidence Queries (SEQs) retrieves citations to published literature related to Healthy People 2020 topic areas and objectives.
