The Impact of Sleep Apnea on Postoperative Utilization of Resources and Adverse Outcomes

Sleep apnea has been associated with increase risk of postoperative complications. The authors show the impact of preoperative sleep apnea not only on an individual level, but also on a societal scale. “530,089 entries were identified for patients undergoing total hip and knee arthroplasty in a national database. In the multivariate analysis, the diagnosis of SA emerged as an independent risk factor for major postoperative complications (OR 1.47; 95% confidence interval [CI], 1.39–1.55). Pulmonary complications were 1.86 (95% CI, 1.65–2.09) times more likely and cardiac complications 1.59 (95% CI, 1.48–1.71) times more likely to occur in patients with SA. In addition, SA patients were more likely to receive ventilatory support, use more intensive care, stepdown and telemetry services, consume more economic resources, and have longer lengths of hospitalization.
