Abstract

Background: Previous studies have found an association between functional status and outcomes following hip and knee arthroplasty. The purpose of this study was to evaluate the effect of dependent functional status on outcomes after total shoulder arthroplasty (TSA). Methods: The American College of Surgeons National Surgical Quality Improvement Program was used to identify patients who underwent primary TSA (anatomic or reverse) for glenohumeral osteoarthritis from January 1, 2011 to December 31, 2016. Patients whose preoperative functional status was dependent were compared with independent patients. Demographic data, length of hospital stay, and postoperative complications within 30 days were analyzed. Multivariable logistic regression was used to isolate the effect of functional status on postoperative complications and readmission. Results: A total of 12,982 patients underwent primary TSA (anatomic or reverse) and 3.2% had a dependent functional status. Dependent patients had higher rate of comorbidities, higher mean American Society of Anesthesiologists class, longer hospital stays, and higher complication rates (including pneumonia, urinary tract infection, and blood transfusion). Logistic regression revealed that dependent functional status was an independent predictor for occurrence of any complication (odds ratio 2.0, P < .01) and for readmission (odds ratio 2.6, P < .01). Conclusion: Patients with dependent functional status preoperatively are at increased risk for short-term complications and readmission within 30 days following primary TSA. Level of evidence:: Level III
