What is Evidence-Based Practice?

Evidence-based medicine is the conscientious, explicit and judicious use of current best evidence in making decisions about the care of individual patients.1

Evidence-based practice (EBP) is therefore the process of combining both expertise and research in order to make informed decisions in the care of patients.2


EBP involves:

  1. Asking focused questions (using the PICO model) about how to care for or address a problem in the clinical setting;
  2. Finding the evidence to support specific treatment methods or solutions;
  3. Appraising the evidence for validity, clinical relevance, and applicability;
  4. Making a decision, and applying research evidence in practice;
  5. and Evaluating the performance of the medical intervention, treatment, or solution for future practice.

Strong, refined research and information literacy skills are essential for evidence-based practice, and practitioners must be able to locate, evaluate, and apply research to their clinical practice.

Evidence-Based Practice requires a clinician or researcher to locate the best evidence and information to inform healthcare decision-making.

To refine your search in CINAHL, try one of the following:

  • Select Evidence-Based Practice under Refine Your Results;
  • In the Advanced Search menu, select Systematic Review or Practice Guidelines from the Publication Type list;
  • In the Advanced Search menu, select Review from the Clinical Queries list:
  • Sensitivity retrieves all related articles, including some material that may not be relevant to your search.
    • High Specificity is a targeted search that will only retrieve highly relevant results - some results may therefore be missed.
    • Best Balance balances the search between sensitivity and specificity.
