Audit and feedback continues to be widely used as a strategy to improve professional practice. It appears logical that healthcare professionals would be prompted to modify their practice if given feedback that their clinical practice was inconsistent with that of their peers or accepted guidelines. Yet, audit and feedback has not consistently been found to be effective. Providing healthcare professionals with data about their performance (audit and feedback) may help improve their practice. Audit and feedback can improve professional practice, but the effects are variable. When it is effective, the effects are generally small to moderate. The results of this review do not support mandatory or unevaluated use of audit and feedback as an intervention to change practice.
