Evidence-based practice (EBP) uses scientific evidence to determine the best practices. EBP emerged in the 1980s and started in England in the early 1990s. EBP involves using the best current evidence from research, clinical expertise, and patient preferences to make decisions about patient care. Implementing EBP requires finding and applying effective interventions through a systematic process. Barriers to EBP include lack of time, support, and research knowledge, but EBP can improve outcomes, consistency of care, and decision-making. Common models for EBP include the John Hopkins, Iowa, and Stetler models.
