RESUMO
Purpose: To estimate the consumption of antibiotics in our hospital and to determine the points at which the recommendations of good practice of antibiotherapy will be targeted. Patients and methods: Our study is a one day prevalence study where antibiotic prescriptions are analyzed by a group of 6 doctors referents in antibiotherapy. During the study day, 443 patients were studied. Means age was 44.2 +/- 23.3 years [range: 1 and 102 years]. 101 infections were diagnosed in 48 patients [10.8%]. 192 patients [43.3%] received antibiotics. Antibiotherapy was curative in 44% of cases. The most prescribed antibiotics were gentamicin [85.2 DDD/1000 patients], metronidazole [79 DDD/1000 patients], and cefotaxime [73.9 DDD/1000 patients]. According to the evaluation group, 30.7% of the antibiotic prescription was considered unjustified. The antibioprophylaxis represents the category most often unjustified [49%]. The molecules in which prescription was frequently considered unjustified are the ciprofloxacin [67%], the amoxicillin-clavulonate [40%] and the cefotaxime [40%]. Our results suggest that an action of good practice should be targeted at the antibioprophylaxis and should concern especially molecules in which prescription was frequently unjustified
