4
MEDLINE
  • Produced by the National Library of Medicine
  • Indexes over 4,700 journals from the mid-1960s
    forward
  • Controlled vocabulary (MeSH) available
  • Premier bibliographic database for information in

ACP Journal Club
  • Database consists of two journals
  • ACP Journal Club
  • Evidence-Based Medicine (BMJ)
  • Titles merged in 2000 new content appears in ACP
    Journal Club
  • Editors of ACP Journal Club

    article for clinical practice
  • No controlled vocabulary

10
Cochrane Central Register of Controlled Trials
  • Bibliographic database of definitive controlled
    trials
  • Intent systematically search the international
    health care literature and create an unbiased
    source of data for those preparing systematic
    reviews
  • Utilizes MeSH and natural language

11
Cochrane Database of Systematic Reviews
  • Produced by the Cochrane Collaboration - an
    international network of individuals and
    institutions
  • Includes two types of reviews
  • Complete Reviews full text systematic reviews,

  • Protocols background, objectives, methods, and
    expected date of completion for reviews currently
    being prepared
  • No controlled vocabulary

12
Database of Abstracts of Reviews of Effects (DARE)
  • Produced by the expert reviewers and information
    staff of the National Health Services' Centre for
    Reviews and Dissemination (NHS CRD) at the

  • Low back pain treatment (drug)

15
Additional Resources
  • ACP Pier
  • National Guideline Clearinghouse
  • Evidence Based Medicine Tool Kit
  • Netting the Evidence
  • Evidence-Based Medicine How to Teach and
    Practice EBM

16
ACP Pier (Physician's Information and Education
Resource)
  • Developed by the American College of Physicians
  • Medical knowledge and guidance resource based on
    evidence
  • Covers 360 disease modules

    Healthcare Research and Quality (AHRQ)
  • Resource to identify clinical practice guidelines
  • Includes links to additional resources, a
    guideline compare tool, and full-text if
    available

18
Evidence Based Medicine Tool Kit
  • Collection of tools for identifying, assessing
    and applying relevant evidence
  • Originally published in JAMA as a result Evidence
    Based Medicine Working Group
  • http//www.med.ualberta.ca/ebm/ebm.htm

19
Netting the Evidence
  • Intended to facilitate evidence-based healthcare
    by providing support and access to helpful
    organizations and useful learning resources
  • Resources can be browsed by type
  • Search engine available
  • http//www.shef.ac.uk/scharr/ir/netting/

20
Evidence-Based Medicine How to Teach and
Practice EBM
  • Tells how to integrate best available evidence
    into clinical expertise
  • Available BHS Library WB 102 F933 2005 (copy on
    reserve and one circulating copy)

21
Things to Keep in Mind
  • All of these resources are
  • Keyword searchable
  • Under development thus limited in scope
