Audit and feedback effective in improving professional practice

Clinical question: 
How effective are audit and feedback on the practice of healthcare professionals and on patient outcomes?
Bottom line: 
Audit and feedback generally led to small but potentially important improvements in professional practice. Feedback was more effective when baseline performance was low, when the source was a supervisor or senior colleague, when it was provided more than once, when it was delivered both verbally and written down, and when it included both measurable targets and an action plan. The effect size varied based on the particular clinical behaviour targeted by the intervention.
Most of the studies measured the effects of audit and feedback on doctors, although some of the studies measured the effect on nurses or pharmacists. It was uncertain whether audit and feedback were more effective when combined with other interventions.
Audit and feedback is widely used as a strategy to improve professional practice either on its own or as a component of multifaceted quality-improvement interventions. This is based on the belief that healthcare professionals are prompted to modify their practice when given performance feedback showing that their clinical practice is inconsistent with a desirable target.
