EBM In General
  • David L. Sackett, OC, FRSC, M.D.
  • The conscientious, explicit and judicious use of
    current best evidence in making decisions about
    the care of individual patients.
  • The practice of Evidence-Based Medicine means
    integrating individual clinical expertise with
    the best available external clinical evidence
    from systematic research.- CEBM, Oxford, UK
  • Current best evidence, Best available
    evidence
  • Integrates clinical expertise
  • Implies levels of evidence
  • No literature may exist

4
Levels of Evidence
5
Types of Questions
  • Therapy, Prevention
  • Etiology, Harm
  • Prognosis
  • Diagnosis
  • Cost Analysis
  • See http//www.cebm.net/levels_of_evidence

6
EBM Components
  • Formulate a clinical question
  • Patient
  • Intervention
  • Comparison
  • Outcome
  • Search information sources
  • Critical appraisal of evidence
  • Apply evidence to care

7
Many EBM Resources
  • Cochrane Library
  • Cochrane Reviews Database of Systematic Reviews
  • D.A.R.E. Database of Abstracts of Reviews of
    Evidence
  • CENTRAL Central Register of Controlled Trials
  • Up-To-Date
  • InfoPOEMs/InfoRetriever

8
EBVM
  • No differences in the processes or goals of EBM
    and EBVM
  • Currently no EBM-focused resources or
    organizations (i.e. Cochrane)
  • Clinical Queries feature in Medline does search
    JAVMA and Veterinary Record
  • Less literature, fewer sources of high-level
    evidence
