what is the meaning of evidence based practice
Evidence-based practice (EBP) is an interdisciplinary approach to clinical practice that has been gaining ground following its formal introduction in 1992. It started in medicine as evidence-based medicine (EBM) and spread to allied health professions, educational fields, and others. EBP is traditionally defined in terms of a "three legged stool" integrating three basic principles: (1) the best available research evidence bearing on whether and why a treatment works, (2) clinical expertise (clinical judgment and experience) to rapidly identify each patient's unique health state and diagnosis, their individual risks and benefits of potential interventions, and (3) client preferences and values.
