Clinical audit is a professional service quality improvement process that promotes quality of patient care and treatment outcomes through a systematic review of activities based on precise criteria and from a perspective of change. Structural, process and outcome aspects are systematically selected and evaluated according to explicit criteria. The changes are implemented at the individual, team, or service level where indicated, and subsequent monitoring is conducted for feedback on any improvement iin provided health care. The clinical audit’s objective is to measure nursing practice in reference to a series of standards. Compared to research activity ( where the main question is what is the right thing to do), in clinical audit the question is whether the right thing is done in the right way. As a part of “clinical governance”, clinical audit aims to ensure that patients receive the best quality of care.
