The aim of our study was to describe the pattern of antibiotic prescriptions for acute respiratory tract infections (RTIs) among the adult population and the factors associated with antibiotic prescribing. Patients and methods: The study involved patients who visited a general practitioner with suspected acute RTI. Patients with diagnosis of acute sinusitis, acute pharyngitis, acute bronchitis, and influenza were included in the study. We evaluated the presence of an indication for antibiotic therapy for selected diseases according to international guidelines. The appropriateness of any prescribed molecule was also evaluated. Results: A total of 1,979 cases of acute RTIs were included: 1,196 (60.4%) pharyngitis, 359 (18.2%) bronchitis, 234 (11.8%) influenza, and 190 (9.6%) sinusitis. An antibiotic prescription was given in 67.3% of the consultations and was not indicated by the guidelines in 66.5% of the total RTIs. Macrolides were the most frequently prescribed antibiotics accounting for 32.5% of all those prescribed, followed by amoxicillin with clavulanic acid (31.1%) and fluoroquinolones (14.2%). The highest overprescription was associated with pharyngitis (65.9%) and the lowest with influenza (4.9%). A throat swab was performed only in 11 of all the patients with a diagnosis of acute pharyngitis. Conclusion: The present study showed a very high frequency of nonevidence-based prescription of antibiotics at the primary care level. Future improvement programs should focus on development of evidence-based guidelines, access to postgraduate training, and better availability of diagnostic tools.
