Objectives: Variations in management of sinusitis in primary care settings can be associated with inappropriate antibiotic prescriptions and delays in treatment. The objective of this study was to identify patient and provider characteristics associated with possible inaccurate diagnosis and management of sinusitis. Methods: We performed a cross-sectional retrospective analysis using an established regional healthcare database of patients who received a diagnosis of sinusitis between 2011 and 2022 from a non-otolaryngologist provider. Patient’s comorbidities, insurance status, chronicity of sinusitis, and prescriptions were included. We noted if patients were referred to an otolaryngology practice and if they received a diagnosis of sinusitis from an otolaryngologist. Results: We analyzed 99 581 unique patients and 168 137 unique encounters. The mean age was 41.5 (±20.4 years) and 35.7% were male. Most patients had private insurance (88.5%), acute sinusitis (81.2%), and were seen at a primary care office (97.8%). Approximately 30% of patients were referred to an otolaryngology practice for sinusitis. Of referred patients, 50.6% did not receive a diagnosis of sinusitis from an otolaryngology practice. Patients without a sinusitis diagnosis by an otolaryngology practice received significantly more mean courses of antibiotics (5.04 vs 2.39, P
