Definition of evidence-based practice (EBP)

EBP delivers the most appropriate care to patients with the use of current research evidence, clinical expertise, and an understanding of the patient (Klem & Weiss, 2005).

Steps of EBP

1. Ask: Formulate an answerable question (Do you have an example of a PICO clinical question?)

2. Acquire: Find the best available evidence or resources to answer the question

3. Appraise: Critically appraise the evidence for validity, impact, relevance, and applicability

4. Apply: Implement the results by combining  the evidence and clinical expertise

5. Evaluate:  Access effectiveness of the decision
