Nursing audit is defined as the process of collecting information from nursing reports and other documented evidence about patient care and assessing the quality of care using quality assurance programs. The purposes of nursing audit include evaluating nursing care given, achieving desired quality of nursing care, stimulating better record keeping, focusing on care provided rather than the care provider, and contributing to research. Nursing audit uses written standards of care to evaluate nursing practice and identify areas for corrective action and quality improvement. It can be used as a tool for quality control through outcome, process, and structure audits.
