Evidence-Based Practice (EBP) is defined as the conscientious, explicit, and judicious use of current best evidence in making decisions (Sackett, Rosenberg, Gray, Haynes, & Richardson, 1996).
With its origins in medicine, evidence-based practice has been applied to other health fields, and also to social science (e.g., criminal justice, social work) and education fields. Evidence-based practice is constantly being modified to best suit the subject to where it is applied.
Various disciplines have defined evidence-based practice steps based on their needs. They have their specific steps, but the general steps consist of the following (Booth & Brice, 2004):
1. Defining the Problem: convert a precise information need from practice into an answerable, focused, structured question.
2. Finding Evidence: search the information resources (professional literature, databases, etc.) relevant to the topic in question
3. Critical Appraisal/ Appraising Evidence: examine a resource's validity, reliability, and applicability to the question or problem.
4. Integrating or Applying Results of Appraisal: integrate new information with one's own knowledge base and patient/scenario preferences, and apply to practice.
5. Re-evaluating the Process: review the process, outcome, and possible ways to improve practice.
