It has acceptable oncological outcomes with good function. The purpose of this study was to investigate whether patients with depressive disorders undergoing primary total shoulder arthroplasty have higher rates of (1) in-hospital lengths of stay, (2) readmission rates, (3) medical complications, and (4) implant-related complications. A retrospective query was performed using a national claims database. Study group patients were matched to controls in a 15 ratio according to age, sex, and medical comorbidities. The query yielded 113,648 patients who were with (n = 18,953) and without (n = 94,695) depressive disorders. Pearson's χ analyses were used to compare patient demographics. Logistic regression analyses were used to calculate odds-ratios of complications and readmission rates. Welch's tests were used to test for significance for in-hospital lengths of stay. A value less than 0.003 was considered statistically significant. Study group patients had significantly longer in-hospital lengths of stay (2.7 days versus 2.3 days; 0.0001). Patients who have depressive disorders had higher incidences and odds of readmissions (9.4 versus 6.15%; odds-ratio 1.6, 0.0001), medical complications (2.7 versus 0.9%; odds-ratio 3.0, 0.0001), and implant-related complications (6.1 versus 2.4%; odds-ratio 2.59, 0.0001) compared to controls. Depressive disorder patients have longer in-hospital lengths of stay and increased odds of readmissions and complications following primary total shoulder arthroplasty.
