Abstract
Study designRetrospective cohort study.ObjectivesTo examine differences in postoperative complications, recovery course, and costs between patients with and without obstructive sleep apnea (OSA) undergoing single-level anterior cervical discectomy and fusion (ACDF).MethodsThe National Inpatient Sample (NIS) database was queried to identify patients undergoing single-level ACDF between 2016 and 2022. After exclusions, patients were divided into OSA and control groups. Propensity score matching (1:2) controlled for age, sex, obesity, and year of surgery to balance characteristics. Postoperative outcomes, including complications, length of stay (LOS), hospital costs, and discharge disposition, were compared using chi-square tests for categorical variables and t-tests for continuous variables. A Bonferroni correction was applied, with significance set at P < 0.002.ResultsA total of 36,000 matched cases were analyzed (12,000 OSA and 24,000 controls). OSA patients had significantly higher rates of acute respiratory failure (4.7% vs 1.9%; P < 0.001) and mechanical ventilation (1.5% vs 0.6%; P < 0.001). The OSA cohort also had a longer LOS (2.3 vs 1.9 days; P < 0.001), higher hospital costs ($23,300 vs $21,100; P < 0.001), and greater non-routine discharge rates (20.4% vs 16.8%; P < 0.001).ConclusionsOSA is associated with increased respiratory complications, prolonged LOS, and higher costs in single-level ACDF. These findings underscore the importance of preoperative screening and tailored perioperative management to improve outcomes in this high-risk population.
