Children Undergoing Laryngeal Surgery for Obstructive Sleep Apnea: NSQIP Analysis of Length of Stay, Readmissions, and Reoperations

Objective: No national study to date has specifically evaluated the predictive variables associated with extended hospitalization and other postoperative complications following laryngeal surgery in children with obstructive sleep apnea (OSA). The goals of this study were to identify perioperative risk factors and provide a descriptive analysis of surgical outcomes in these children using the National Surgical Quality Improvement Program-Pediatrics (NSQIP-P) database. Methods: Patients aged 0 to 18 years who underwent laryngeal surgery with a postoperative diagnosis of OSA were queried via the 2014-2018 NSQIP-P database using Current Procedural Terminology code 31541. Variables collected included age, sex, ethnicity, body mass index (BMI), medical comorbidities, American Society of Anesthesiologists (ASA) physical classification, operative time, and concurrent procedures. Endpoints of interest were length of stay, unplanned reoperation, readmission, reintubation, and postoperative complications. Univariate and multivariate linear regression analyses were performed. Results: A total of 181 cases were identified (57.5% male and 42.5% female, mean age 4.36 years, range 14 days-17.7 years). Body mass index (P = .015, OR = 0.96), structural CNS abnormality (P = .034, OR = 1.95), preoperative oxygen supplementation (P = .043, OR = 1.28), operative time (P = .019, OR = 1.84, 95% CI = 1.28-2.54), and concurrent procedure (P < .001, OR = 2.21) were all independently associated with LOS. Postoperative complications had no significantly associated variables, with an overall low incidence of readmission (5.0%), reoperation (1.7%), and reintubation (1.1%). Conclusion: In this data set, children with OSA undergoing laryngeal surgery experienced minimal postoperative complications. Recognition of the factors associated with increased LOS could lead to improvement in the quality of care for children with OSA.
