Interdisciplinary Studies in Health Science (IDS): Evidence-Based Practice

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.
