title: Long-lasting improvement in general practitioners' prescribing of antibiotics by means of medical audit.
abstract: OBJECTIVE
  To evaluate the usefulness of medical audit of GPs' antibiotic prescription habits.
  
  
  METHODS
  Medical audit according to the APO method. Registration of antibiotic prescriptions for respiratory tract infections during a 3 year period. Intervention with courses, visits to the laboratory, and distribution of recommendations concerning diagnosis and treatment of respiratory infections.
  
  
  METHODS
  24 Danish GPs in cooperation with Audit Project Odense (APO) and Department of Clinical Microbiology, Odense University Hospital. 207 GPs acted as controls.
  
  
  METHODS
  Changes in the number of antibiotic prescriptions and in the penicillin/broad-spectrum antibiotic ratio.
  
  
  RESULTS
  The proportion of antibiotic prescriptions was reduced during the investigation period, but a similar reduction was found in the control groups. Only for acute sinusitis was a lasting decrease not found in the control groups recorded. The penicillin/broad-spectrum antibiotic ratio increased in the intervention group (1.33 in 1992, 1.94 in 1993 and 2.70 in 1995). This increase was significantly higher than in the control groups. The change was seen for acute sinusitis, bronchitis, and pneumonia, but not for acute otitis media or acute tonsillitis. The changes induced from 1992 to 1993 were maintained or increased from 1993 to 1995 although the educational measures had stopped.
  
  
  CONCLUSIONS
  Medical audit according to the APO method is a useful tool for inducing and maintaining desirable changes in GPs' prescription habits.
