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.
