Pattern and appropriateness of antibiotic prescriptions for upper respiratory tract infections in primary care paediatric patients.

OBJECTIVES: The aim of this cross-sectional study was to investigate the pattern of antibiotic prescriptions for upper respiratory tract infections (URTIs) in children seen by primary care paediatricians (PCPs). METHODS: Data were collected from face-to-face interviews administered to a sample of parents of outpatient children aged 0-14 years in two regions in Southern Italy. To be eligible, children had to be diagnosed with sinusitis, pharyngotonsillitis, otitis media, bronchitis, influenza or a common cold. The presence of an indication of antibiotic therapy was evaluated according to national and international guidelines. RESULTS: An antibiotic prescription was indicated in 57 (10.1%) of the sampled patients, of whom 33.3% did not receive an antibiotic prescription; among the 508 patients for whom an antibiotic prescription was not indicated, 27.4% received a prescription. Of all PCP consultations, 72% were appropriate (an antibiotic was prescribed when indicated and not prescribed when not indicated), whilst an antibiotic prescription not indicated by guidelines was given to 24.6% of the participants, and 3.4% of the sample did not receive an antibiotic prescription when indicated. The most frequently prescribed antibiotic was amoxicillin with clavulanic acid. A rapid microbiological examination was performed in two patients. CONCLUSIONS: The study findings highlight a high rate of sub-optimal antibiotic therapeutic profile. Over-prescription of antibiotic therapy and the use of broad-spectrum molecules are widespread in children with URTIs. Antibiotic under-prescription, which may deprive paediatric patients of an effective treatment when indicated, also occurs.

Prevalence of methicillin-resistant Staphylococcus aureus (MRSA) carriage and pattern of antibiotic resistance among sheep farmers from Southern Italy.

PURPOSE: We conducted a cross-sectional study to measure the prevalence of methicillin-resistant Staphylococcus aureus (MRSA) colonization, with a particular focus on livestock associated (LA)-MRSA in farmers working in contact with livestock (sheep) in one Italian region. Furthermore, we have assessed the antimicrobial resistance pattern of isolates and the association of carriage with specific characteristic of farms and working tasks. PATIENTS AND METHODS: Demographic data, occupational history, and contact with animals information was collected. Nasal and oropharyngeal swabs were collected and all samples were tested for the isolation and identification of S. aureus. Isolates were examined for antimicrobial susceptibility and all MRSA strains underwent molecular analyses through multiple-locus variable number of tandem repeat analysis (MLVA). RESULTS: A total of 115 sheep farms and 275 sheep farmers were enrolled. MRSA colonized workers were found in three farms; S. aureus was isolated in 97 workers (35.5%), whereas MRSA was isolated in 3 (1.1%) workers. All MRSA isolates were classified as multidrug resistant. Two of the MRSA isolates were resistant to quinupristin/dalfopristin (QDA), mupirocin, erythromycin, and tetracycline. Among methicillin-susceptible S. aureus (MSSA), 32 (34%) were resistant to tetracycline, 31 (33%) to erythromycin, 26 (27.6%) to QDA, and 22 (23.4%) to linezolid and clindamycin. One MRSA belonged to MLVA complex (MC) 001, found to colonize both humans and animals. CONCLUSION: The picture of MRSA transmission among sheep farmers does not seem to be critical, although there is the need to improve adequate control measures to prevent and minimize any biological risk in sheep farms for both animal and human health. Specific monitoring/surveillance programs would help in better understanding the epidemiology of resistant strains.
