Obstructive sleep apnea as a risk factor for postoperative complications after revision joint arthroplasty

Abstract

Although current evidence is limited, obstructive sleep apnea (OSA) has been suggested as a risk factor for morbidity after primary joint arthroplasty. Our objective was to determine if patients with OSA have a higher likelihood of postoperative in-hospital complications or increased costs after revision arthroplasty. The Nationwide Inpatient Sample was used to identify 258-455 patients who underwent revision total hip arthroplasty or revision total knee arthroplasty between 2006 and 2008. Of these patients, 16-608 (6.4%) had been diagnosed with OSA. Multivariate analysis with logistic regression modeling was used to compare patients with and without OSA. Obstructive sleep apnea was associated with increased in-hospital mortality (odds ratio, 1.9; P = .002), pulmonary embolism (odds ratio, 2.1; P = .001), wound hematomas or seromas (odds ratio, 1.36; P < .001), and increased postoperative charges ($61-044 vs $58-813; P < .001).
