Abstract
Antibiotic stewardship requires clear insight into antibiotic overuse and the syndromes that lead to prescription. The aim of this study was to estimate the proportion of antibiotic prescriptions attributable to acute lower respiratory tract infections (LRTIs) during the cold season. Using individual data from the French National Health Insurance (NHI) database, weekly time series were constructed of outpatient antibiotic (beta-lactams and macrolides) prescriptions between January 2010 and December 2017. Time series were also constructed of tenth edition of the International Classification of Diseases (ICD-10) discharge diagnoses from a national network of emergency departments (EDs), stratified by specific syndromes (pneumonia, bronchitis, bronchiolitis and influenza-like illness). The number of outpatient antibiotic prescriptions attributable to these syndromes during the cold season in France was modeled and estimated for the entire population, young children (≤5 years) and the elderly (≥75 years). LRTIs accounted for 40% (95% confidence interval [95% CI]: 29, 52) of outpatient antibiotic use during the cold season for the entire population, including 23% (95% CI: 13, 33) and 17% (95% CI: 13, 22) for bacterial and viral infections, respectively. In children and the elderly, viral LRTIs were the reason for 38% (95% CI: 31, 46) and 20% (95% CI: 16, 25) of outpatient antibiotic use, respectively (with bronchiolitis accountable for half of use in young children). In the entire population and in children, respectively, outpatient antibiotic overuse attributable to viral LRTIs was estimated to be 289 (95% CI: 221, 374) and 1588 (95% CI: 1295, 1922) prescriptions per 100 000 inhabitants per week. These results highlight the major role of viral infections in driving antibiotic prescriptions, particularly in young children.
