title: [Adequate prescription of antibiotic therapy for urinary tract infections in hospital: identifying and correcting non-observance of guidelines].
abstract: OBJECTIVE
  We analyzed the adequacy of antibiotic therapy prescribed for urinary tract infections (UTI): prostatitis, pyelonephritis, indwelling catheter-associated UTIs, or other undefined UTIs.
  
  
  METHODS
  The adequacy of prescriptions to local guidelines was assessed retrospectively in two wards (Internal Medicine and Surgical Urology) of the Nantes University Hospital. The principal criteria involved simultaneously: choice of the molecule, dose, and treatment duration. Non-observances of guidelines were major (non-adequacy of the molecule, prescription of a non-active molecule according to in vitro susceptibility tests, non-appropriate treatment abstention), or minor (non-justified treatment, non-justified bitherapy, no prescription of bitherapy when requested, no treatment adaptation when requested, too short or too long treatment length, dosage mistakes).
  
  
  RESULTS
  One thousand eighty-six infections were collected over a 24-month period. The overall rate of adequate prescriptions was 40.1% (46.6% in Internal Medicine and 36.5% in Surgical Urology). In Internal Medicine (226 non observance among 389 prescriptions), the ratio of major non-observance of guidelines was 9.8%. Among them, 44.7% were non-appropriate treatment abstentions. In Surgical Urology (539 non observance out of 695 prescriptions), non-observance related to treatment length were the most frequent. The ratio of major non-observance was 19.9%. Among them, non-adequacy of the molecule reached 60.7%. Non-justified treatment and non-appropriate bitherapies were frequent.
  
  
  CONCLUSIONS
  For both units, indwelling catheter-related UTIs and other UTIs accounted for more than 50% of the infections although not detailed in the local guidelines. Identifying and analyzing Non observance may lead to targeted correcting actions to improve prescription quality.
