The 5 As of Evidence-based Practice (EBP)

Five Step Model of Evidence Based Practice


The 5 "A's" will help you to remember the EBP process:

  1. ASK:  Information needs from practice are converted into focused, structured questions.
  2. ACCESS / ACQUIRE:  The focused questions are used as a basis for literature searching in order to identify relevant external  evidence from research.
  3. APPRAISE:  The research evidence is critically appraised for validity.
  4. APPLY: The best available evidence is used alongside clinical expertise and the patient's perspective to plan care.
  5. ASSESS / AUDIT:  Performance is evaluated through a process of self reflection, audit, or peer assessment.

Please note, there are several models for EBP with various named and numbered steps.  This guide will detail the first three steps ASK, ACCESS/ACQUIRE, APPRAISE.  Some models include a 6th step for DISSEMINATE.
