he aim of this retrospective analysis was to investigate the impact of OSA on perioperative complications, inpatient mortality, and cost in spinal fusion surgey.
Hospitalizations (2009-2011) were identified using the Nationwide Inpatient Sample.
Multivariable regression analysis demonstrated that OSA had a significant independent association with slightly increased respiratory (OR 1.13, CI 1.09-1.16), urinary and renal (OR 1.11, CI 1.07-1.16) or overall inpatient complications (OR 1.05, CI 1.02-1.05). OSA was also associated with lower inpatient mortality (OR 0.39, CI 0.33-0.45).
While OSA was associated with slightly higher inpatient complication rates it was not a predictor of inpatient mortality, which could hypothetically be based on the current implementation of perioperative OSA optimization and management strategies.
