Evidence Based Practice was first defined by Dr David Sackett in the 1990s, but a more recent definition is:
“integrating the best available research evidence with clinical expertise and the patient’s unique values and circumstances” (Straus, Glasziou, Richardson, & Haynes, 2011).
In addition, it "...requires the health professional to take into account characteristics of the practice context in which they work" (Hoffman, Bennett, & Mar, 2016, p.4).
Evidence-Based Practice has expanded from the original Evidence-Based Medicine to apply to other health professions and many other disciplines such as librarianship and education.
There are various models for listing the steps in the Evidence-Based Practice process. Here is a common 5-step approach:
|1||Ask the question - Express the problem as a clinical question|
|2||Acquire the evidence - Find evidence-based research to address the question|
|3||Appraise the evidence - Critically appraise the evidence to assess its validity|
|4||Apply the evidence - to the patient or the problem|
|5||Re-evaluate the evidence - Assess and audit the process|
