What Is Evidence-Based Practice?

Evidence Based Practice in Nursing

According to Johns Hopkins University, EBP is "a three-phase approach referred to as the PET process: practice question, evidence, and translation. In the first phase, the team develops a practice question by identifying the patient population, interventions, and outcomes (PICO). In the second phase, a literature search is performed, and the evidence is appraised for strength and quality. In the third phase, the findings are synthesized to develop recommendations for practice."
