National Trends in Chronic Rhinosinusitis and Inpatient Sinus Surgery in Adults with Cystic Fibrosis.

Abstract

Objective: Given the recent dramatic changes in medical therapy for cystic fibrosis (CF), this study aims to describe temporal changes in chronic rhinosinusitis (CRS) and endoscopic sinus surgery (ESS) rates.

Methods: National Inpatient Sample (2004-2019; weighted estimates for 119,067 pediatric and 202,407 adult patients) was used to analyze adult (age ≥18 years) and pediatric patients with CF with pulmonary manifestations. Comorbid CRS, ESS rates, and extended length of stay (LOS, ≥75th percentile) were analyzed.

Results: The rate of CRS in both pediatric (14.1% vs 21.1%, P < .001) and adult (16.5% vs 40.9%, P < .001) patients increased. Rate of ESS in pediatric patients with CRS decreased from 25.3% to 3.4% (P < .001). A similar decline occurred in adults with CRS (12.3% vs 3.6%, P < .001). In multivariate analysis from 2015 to 2019, ESS and extended LOS were associated with admission in the Western United States (P < .001). CRS (OR 1.14, P = .002) and ESS (OR 1.78, P = .002) were independent predictors of extended LOS. Elective admission, primary insurance, race, and hospital teaching/location were significantly associated with ESS and extended LOS (P < .05).

Conclusion: Despite the increased prevalence of CRS in adults and pediatric patients with CF, rates of inpatient ESS have declined from 2004 to 2019. Patient and hospital factors affect undergoing ESS in 2015 to 2019. CRS and ESS are associated with extended LOS in recent years.
