Predictors of Blood Transfusion in Patients Undergoing Total Shoulder Arthroplasty
Abstract
ABSTRACT Background Anatomic total shoulder arthroplasty (TSA) and reverse total shoulder arthroplasty (RSA) are major surgeries that may result in significant blood loss and the need for transfusion. The purpose of this study was to identify predictors for blood transfusion in patients undergoing TSA. Methods The American College of Surgeons National Surgical Quality Improvement Program was used to identify 12,982 patients who underwent TSA (anatomic or reverse) from Jan 1, 2011 to Dec 31, 2016. \xa0We compared patients who underwent intraoperative or postoperative blood transfusion with those who did not receive a blood transfusion. Multivariable logistic regression was used to determine independent factors associated with blood transfusion. Results The rate of intraoperative and postoperative blood transfusion was 3.5% during the study period. Compared with patients who did not receive a blood transfusion, those who did were older (73.4 versus 68.9 years, P Conclusion In patients undergoing shoulder arthroplasty, preoperative factors such as ASA classification, smoking, and functional status can be used to identify patients at increased risk for requiring blood transfusion.
