RESUMO
Drug utilisation studies have shown wide differences, among different countries, in the prescribing behaviour in general practice. In Italy, for instance, the choice of antibiotic prescription seems to show a wider use of parental antibiotic. Aim of this study was to describe antibiotic prescribing pattern and therapeutic doses used by Sicilian general practitioners (GPs) and evaluate their prescribing attitudes regarding the use of parental ones. Each practitioner had to fill a questionnaire for each therapeutic intervention ended with an antibiotic prescription during a period of 6 months. Diagnosis and drugs were classified according to the International Classification of Diseases (ICD-10) and to Anatomical Therapeutic Chemical Classification (ATC), respectively. On 9395 prescriptions performed by 76 doctors of 25 Sicilian towns, the analysis indicated that acute respiratory symptoms represent the commonest indication (31.7%) for a medical consultation, and that Macrolides [such as azithromycin (8.8%) and clarithromycin (8.3%)], Penicillin [such as amoxycillin (7.1%%) and co-amoxiclav (8.4%)], III generation of Cephalosporins [such as cefixime (5.5%) and ceftriaxone (5.1%)] represent the most common used therapeutic groups. The choice of the route of administration was influenced by age of the patients and, more significantly, by symptoms and signs of the disease, rather than by bacteria suspected to cause the disease. In conclusion, our data clearly indicate lack of knowledge of antibacterial therapy guidelines among GPs in Sicily, as well as the need of an independent educational training in order to improve knowledge of antibiotics and to decrease the cost of the health care.
