What is Evidence based practice?

First defined by David Sacket (1996), evidence based practice is “the conscientious, explicit and judicious use of current best evidence in making decisions about the care of the individual patient. It means integrating individual clinical expertise with the best available external clinical evidence from systematic research".

More recently Hoffman et al. (2016), defines Evidence based practice (EBP) as "the integration of the best research evidence with clinical expertise and the patient’s unique values and circumstances. Additionally, it also requires the health professional to take into account characteristics of the practice context in which they work" (p.3).

Five steps of Evidence-based practice

Five key steps in Evidence based practice, these include:

1. Ask: a structured and focused clinical question

2. Acquire: Identify appropriate resources & search for the best research evidence to answer your question. 

3. Appraise: Appraise the evidence for its validity (closeness to the truth), impact and applicability (usefulness in clinical practice)

4. Apply: the evidence to the practice setting

5. Assess: evaluating effectiveness and efficiency in executing steps 1 to 4
