- This report describes how audit can be made effective. Drawing on the experience of people who have been involved in organising audit in primary care, it suggests how medical audit advisory groups (MAAGs) could help all practitioners to take part in relevant and worthwhile audit. With the help of lively and succinct examples, the authors show how audit can help in the development of primary care, from solving modest individual problems to implementing and evaluating service-wide changes in care. They recommend changes in the way audit is carried out to increase its impact on the quality of primary care. The report concludes with a positive assessment of the future for audit as part of the wider concern for quality and accountability in health.
