Perioperative complications in patients with sleep apnea following primary total shoulder arthroplasty: An analysis of 33,366 patients.

Introduction: The study evaluated whether sleep apnea (SA) patients undergoing total shoulder arthroplasty (TSA) are at greater odds of: 1) medical complications; 2) implant-related complications; 3) readmission rates; and 4) costs.

Methods: Complications and readmissions were assessed using logistic regression analysis. Welch's -test was used to compare CCI and cost between cohorts.

Results: 33,366 patients equally distributed in both cohorts. SA increased the odds of medical [Odds-ratio (OR)]: 2.52, p < 0.001) and implant-related complications (OR: 1.43, p < 0.001). Readmission rates were similar to controls (OR: 0.99, p = 0.878), whereas costs were higher (p < 0.001).

Conclusion: SA increases complications and costs following TSA.
