(A1103) Adult Inpatient Acute Rhinosinusitis Management and Outcomes Stratified by Age and Sex

Introduction: This study aims to compare the management of male and female inpatients with acute rhinosinusitis (ARS) within the following age cohorts: 18-40 years, 41-59 years, and ≥60 years.

Methods: Using the 2017 National Inpatient Sample, adult inpatients (>18 years old) with ARS were identified (ICD-10: J01). Patients with orbital and intracranial complications were identified using respective ICD-10 codes. Univariate and multivariable analyses were used to determine statistical associations by sex. Weighted measures were reported to provide national estimates.

Results: Among 4,355 adult inpatients with ARS, 2,555 (58.7%) were female and 1,800 (41.3%) were male. Males were younger than females (mean, 56.89 vs 61.14 years; P<.001). On multivariable analysis, males had greater total charges ($44,878 vs $37,188, P< 0.001), length of stay (LOS) (4.09 vs 3.66 days, P=.003), and odds for intracranial complications (OR, 5.740; P< 0.001) than females. Although males underwent a similar number of total procedures as females (1.25 vs 1.02, P=0.053), age stratification revealed males aged ≥60 years had greater total charges, length of stay, and numbers of procedures undergone (1.13 vs 0.78, P < 0.001) than females in this age group.

Conclusions: In a cohort of adult inpatients with ARS, males had greater total charges, LOS, and odds for intracranial complications. Males aged ≥60 years also had a greater number of procedures undergone than females in this age group.
