Some commentators have the EBP practice of consisting of only four steps - Ask, Acquire, Appraise, Apply - see for example Part 2 of Del Mar, Glasziou, & Salisbury's Evidence-Based Practice Workbook (2007) - but most commentators add a fifth step of assess and/or audit.
This involves assessing/auditing the effectiveness and efficiency of the process and practice of evidence-based practice, identifying strengths and weaknesses and ways that it might be improved the next time.
