Pediatric acquired subglottic stenosis: Associated costs and comorbidities of 7,981 hospitalizations

Objectives: Numerous risk factors have been characterized for acquired subglottic stenosis (ASGS) in the pediatric population. This analysis explores the comorbidities of hospitalized ASGS patients in the United States and associated costs and length of stay (LOS). Methods: A retrospective analysis of the Kids' Inpatient Database (KID) from 2009 to 2012 for inpatients <= 20 years of age who were diagnosed with ASGS. International Classification of Diseases, Clinical Modification, Version 9 diagnosis codes were used to extract diagnoses of interest from 14, 045, 425 weighted discharges across 4179 hospitals in the United States. An algorithm was created to identify the most common co-diagnoses and subsequently evaluated for total charges and LOS. Results: ASGS was found in 7981 (0.06%) of total discharges. The mean LOS in discharges with ASGS is 13.11 days while the mean total charge in discharges with ASGS is $114,625; these values are significantly greater in discharges with ASGS than discharges without ASGS. Patients with ASGS have greater odds of being co-diagnosed with gastroesophageal reflux, Trisomy 21, other upper airway anomalies and asthma, while they have lower odds of being diagnosed with prematurity and dehydration. Aside from Trisomy 21 and asthma, hospitalizations of ASGS patients with the aforementioned comorbidities incurred a greater LOS and mean total charge. Conclusion: Our analysis identifies numerous comorbidities in children with ASGS that are associated with increased resource utilization amongst US hospitalizations. The practicing otolaryngologist should continue to advocate interdisciplinary care and be aware of the need for future controlled studies that investigate the management of such comorbidities.
