Definition

Evidence-based practice (EBP) can be defined using different words and descriptions, but all definitions include these 3 basic parts: best available evidence, the professional's clinical expertise, and the patient's circumstances and values.

                                     3 overlapping circles labeled best available evidence, patient values & concerns, and clinical expertise, with the center overlap being EBP

 

The EBP cycle starts with a patient condition, and then moves through 5 steps to aid in the decision making process to provide the best medical care for the patient.

  1. Ask a well-built clinical question
  2. Acquire the best evidence 
  3. Appraise the evidence
  4. Apply the results to the patient  
  5. Evaluate the application to the patient

                                  A semi-circle starting with ask, acquire, appraise, apply, and ending in evealuate to represent the steps of the EBP cycle.

Levels of Evidence

Evidence levels in EBP reflect study design rigor. Higher-tier methods, like RCTs, offer stronger evidence but are less common. The evidence pyramid illustrates this hierarchy-fewer high-level studies, more lower-tier ones. Aim to find/use articles from the RCT level or above when possible.
