Appropriateness of glycopeptide use in a hospital in Italy

Antibiotic prescriptions to adults with acute respiratory tract infections by Italian general practitioners

Purpose

The overuse, misuse, and underuse of antimicrobial agents often lead to the spread of antibiotic-resistant microorganisms. 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.

Point-prevalence study of inappropriate antibiotic use at a tertiary Australian hospital

A point-prevalence study at a tertiary Australian hospital found 199 of 462 inpatients (43%) to be receiving antibiotic therapy. Forty-seven per cent of antibiotic use was discordant with guidelines or microbiological results and hence considered inappropriate. Risk factors for inappropriate antibiotic prescribing included bone/joint infections, the absence of infection, creatinine level >120 µmol/L, carbapenem or macrolide use and being under the care of the aged care/rehabilitation team. In the setting of finite antimicrobial stewardship resources, identification of local determinants for inappropriate antibiotic use may enable more targeted interventions.
