Outcomes and Complications After Spinal Fusion in Patients With Obstructive Sleep Apnea.

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.
