What is Evidence-Based Practice?

In medicine, evidence-based practice (or EBP) is a decision making process about patient care that integrates clinical expertise with the most up-to-date scientific research and evidence and the patient's preference for treatment.

The process of EBP can understood in five steps - the 5 A's:

  1. Ask a clear clinical question - also called a PICO question.
  2. Acquire the best evidence available for your question.
  3. Appraise the evidence for validity using clinical experience and the patient's preferences to determine an intervention/treatment.
  4. Apply the evidence.
  5. Assess the treatment and evaluate the outcomes.

The EBP process is a cycle. After you assess you begin again asking questions about the assessment.
