IntroductionThe objective of this study was to explore race-based differences in 30-day complication rates following total joint arthroplasty (TJA) using a large national database.MethodsPatients undergoing primary, elective THA and TKA between 2012 and 2018 were retrospectively reviewed using the ACS-NSQIP. We compared Black and Hispanic patients with non-Hispanic White patients using multivariate statistical models adjusting for demographic, operative, and medical characteristics.ResultsA total of 324,795 and 200,023 patients undergoing THA and TKA, respectively, were identified. After THA, compared to White patients, Black and Hispanic patients were more likely to be diagnosed with VTE (p < 0.001), receive a blood transfusion (p < 0.001), and to be discharged to an inpatient facility (p < 0.001). After TKA, compared to White patients, Black and Hispanic patients were more likely to experience a major complication (p < 0.001 and p = 0.008, respectively), be diagnosed with VTE (p < 0.001), and be discharged to a facility (p < 0.001).ConclusionsOur findings indicate higher rates of VTE, blood transfusions, and discharge to an inpatient facility for Black and Hispanic patients when compared to White patients following TJA, though we are unable to comment on the etiology of these disparities. These results may contribute to a growing divide with respect to outcomes and access to TJA for these at-risk patient populations.© 2022. The Author(s).
