Impact of audit on preventive measures

Abstract

The results of two reviews of practice records for information about various preventive measures are reported. The reviews were conducted two and a half years apart in the same 29 practices, on roughly 6500 records on each occasion. The first review was carried out during a postgraduate education course involving audit. Two main analyses were undertaken: one concerned with the entire record sample and the other with the individual practice results. Important and substantial improvements were shown in both analyses, which were spread throughout the practices and were not confined to practices at the lower end of the range simply "catching up." The change between the reviews in the mean recorded rates for cervical cytology was 56% to 64%; for rubella immunity 28% to 40%; for polio immunity in adults 15% to 21%; for completed primary immunisation 68% to 78%; for recorded blood pressure 53% to 61%; and for smoking information 22% to 30%. Improvement has been steady but the rate of improvement, especially for recording blood pressure and rubella immunity, has increased since the postgraduate education course.
