Evidence-based medicine is the "conscientious, explicit and judicious use of current best evidence in making decisions about the care of individual patients" (Sackett, DL. BMJ. 1996 Jan 13;312(7023):71-2).
Simultaneously searches evidence-based sources of systematic reviews, practice guidelines, and critically-appraised topics and articles -- including most of those listed above and many more. Also searches MEDLINE's Clinical Queries, medical image databases, e-textbooks, and patient information leaflets.
TRIP Database allows a limited number of free searches.
Filtered resources appraise the quality of studies and often make recommendations for practice.
Authors of a systematic review ask a specific clinical question, perform a comprehensive literature search, eliminate the poorly done studies and attempt to make practice recommendations based on the well-done studies. A meta-analysis is a systematic review that combines all the results of all the studies into a single statistical analysis of results.
Consists of detailed, structured topic reviews of hundreds of articles. Teams of experts complete comprehensive literature reviews, evaluate the literature, and present summaries of the findings of the best studies. Published by the International Cochrane Collaboration.
Full-text database containing structured abstracts of systematic reviews from a variety of medical journals. DARE is produced by the National Health Services' Centre for Reviews and Dissemination (NHS CRD) at the University of York. DARE records cover topics such as diagnosis, prevention, rehabilitation, screening, and treatment.
Also available via Ovid
Systematic Reviews are also searchable in MEDLINE:
Authors of critically-appraised topics evaluate and synthesize multiple research studies.
A comprehensive database of evidence-based clinical practice guidelines and related documents produced by the Agency for Health Care Research and Quality, in partnership with the American Medical Association and the American Association of Health Plans. Updated weekly.
Authors of critically-appraised individual articles evaluate and synopsize individual research studies.
The editors of this journal screen the top 100+ clinical journals and identify studies that are methodologically sound and clinically relevant. An enhanced abstract, with conclusions clearly stated, and a commentary are provided for each selected article. Published by the American College of Physicians-American Society of Internal Medicine.

(e.g., Evidence-Based Medicine, Evidence-Based Mental Health, Evidence-Based Nursing) Primary research articles within the discipline are selected for quality and clinical relevance. A structured abstract and expert commentary are provided for each study.

Evidence is not always available via filtered resources. Searching the primary literature may be required. It is possible to use specific search strategies in MEDLINE and other databases to achieve the highest possible level of evidence. A randomized controlled trial (RCT) is a research study in which participants are randomly allocated into an experimental group or a control group and followed over time for the variables/outcomes of interest. A cohort study is a research study that compares two groups (cohorts) of patients, one that received the exposure of interest and one that did not, and follows these cohorts forward for the outcome of interest. A case-controlled study is a research study which identifies patients with the outcome of interest (cases) and patients without the same outcome (controls), and looks back to see if they had the exposure of interest. A case series is a report on a series of patients with an outcome of interest. No control group is involved. A case report is a report of a patient with an exposure or an outcome of interest.

To limit your PubMed search to the best evidence-producing studies: Click on "clinical queries" (on the left side of the screen). This specialized search is intended for clinicians and has built-in search "filters." Four study categories--therapy, diagnosis, etiology, prognosis--are provided, and you may indicate whether you wish your search to be more sensitive (i.e., include most relevant articles but probably including some less relevant ones) or more specific (i.e., including mostly relevant articles but probably omit a few).

Background Information/Expert Opinion
Physician authors and editors contribute to the eMedicine Clinical Knowledge Base, which contains articles on 7,000 diseases and disorders. The evidence-based content provides the latest practice guidelines in 62 medical specialties. eMedicine's professional content undergoes multiple levels of physician peer review.
