What is Evidence-Based Practice?

Originally coined as Evidence-Based Medicine, the concept has been expanded over the years to include a variety of disciplines and fields.  As such, you may see references to Evidence-Based Medicine, Evidence-Based Dentistry, Evidence-Based Nursing, and others.

However, for the most part these all refer to the same basic concept of Evidence-Based Practice (EBP), or using the best evidence available, combined with the practitioner's clinical expertise and the patient's preferences, to inform the care of patients.

EBP is typically broken down into 5 main steps:

  • Ask a focused clinical question
  • Acquire evidence to answer the question
  • Appraise the evidence found for quality and rigor
  • Apply the evidence to patient care
  • Assess the effect of this application on patient outcomes

What is evidence based nursing?

"an integration of the best evidence available, nursing expertise, and the values and preferences of the individuals, families, and communities who are served."

What is evidence based medicine?

"Evidence based medicine is 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."
