PY - 2020 T2 - Tintinalli's Emergency Medicine: A Comprehensive Study Guide, 9e AB - Acute bacterial sinusitis is a bacterial infection of one or more of the paranasal sinuses lasting <30 days.1 The most common predisposing factor is a viral upper respiratory infection (URI). The incidence of viral URIs in children age 6 to 35 months is approximately six episodes per patient-year, with approximately 8% of those becoming complicated by acute bacterial sinusitis. Bacterial sinusitis in children is most common in the 12 to 23 months age group, probably because these children are most likely to be in day care, predisposing them to URIs.2,3 The cost of acute pediatric bacterial sinusitis in the United States is approximately $20,000 per hospitalized patient, and a large geographic variation in healthcare utilization exists.4 Total healthcare costs in the United States incurred from treating sinusitis in children <12 years of age had been estimated at close to $2 billion a year.5 SN - PB - McGraw-Hill Education CY - New York, NY Y2 - 2024/03/29 UR - accessemergencymedicine.mhmedical.com/content.aspx?aid=1166593680 ER -
