Conducting a Literature Review for Health Sciences: Evidence-based Literature

What is Evidence-based Literature?

  • Evidence-based literature often has the "good housekeeping seal"
  • Systematic reviews, meta-analysis, randomized controlled trials (RCTs), guidelines, etc. are considered evidence-based.  These documents are often available in databases where the information has been already filtered (e.g. Cochrane Library)
  • Helpful in locating the best interventions, programs, etc.
  • Evidence-based practice is "a problem-solving approach to clinical practice that integrates appraisal of the most relevant scientific evidence to answer a clinical question, one’s own clinical experience, and client preferences and values."
