Abstract

Background Acute rhinosinusitis (ARS) is one of the most encountered conditions in primary care and otolaryngology clinics. However, little is known about how antibiotic prescription practices following a diagnosis of ARS compare to guidelines set forth by the American Academy of Otolaryngology in 2015. Objective To investigate the epidemiology of ARS and the corresponding antibiotic prescribing practices by physicians and compare to published guidelines. Methods Using the TriNetX Live database, we identified all patients diagnosed with ARS using the ICD10 code J01 between April 2015 and December 2022 across the state of Tennessee. After investigating the demographics of this cohort, we compared the first prescribed antibiotic within one day of ARS diagnosis to published guidelines. Antibiotics were grouped into their respective classes. Results Of 81 310 patients diagnosed with ARS identified in the specified time frame, 66% were Female, 49% were African American, 44% were White, and the mean age was 47 ± 20 years. The six most common initial antibiotics prescribed for ARS were erythromycins/macrolides [14 609 (25.8%)], amoxicillin/clavulanate [14 322 (25.3%)], amoxicillin [9300 (16.4%)], third generation cephalosporins [7733 (13.6%)], quinolones [3648 (6.4%)] and tetracyclines [2235 (3.9%)]. Of this cohort, 56 719 patients (69.8%) of patients were prescribed an antibiotic within one day of diagnosis. Conclusion Despite published guidelines recommending amoxicillin with or without clavulanic acid as first-line treatment for ARS, only 42.2% of prescribed antibiotics followed this guideline in our cohort. While accounting for patients with penicillin allergy, the second-most represented antibiotics were erythromycins/macrolides, which are specifically recommended against due to high rates of S. Pneumoniae resistance. Our results suggest that further investigation into the causes of erythromycin/macrolide prescriptions as first line treatment for ARS and practices at other institutions should be conducted. In addition, building awareness around published ARS guidelines for physicians may be useful in improving antibiotic stewardship in treatment of ARS.
