RACE AND OUTCOMES IN TOTAL HIP ARTHROPLASTY SURGERY

International Hip Society (IHS) Closed Meeting, Berlin, Germany, 3–5 November 2021.



Abstract

In health care, several studies have suggested worse outcomes in African-Americans. Our objective was to study the relationships of race with outcomes in a series of total hip arthroplasty (THA) cases.

A consecutive series of 2,435 total hip/knee arthroplasties (primaries and revisions) performed in a single hospital by a single surgeon were studied. Revisions due to infections were excluded. Data on race was available for 718 THAs which were finally included. Cases of African-Americans (AA) (n=55) and Whites (n=663) were compared on baseline demographics, Charlson, ASA, preoperative-diagnosis; preoperative and postoperative pain intensity/frequency visual-analogue-scale, QWB-7, SF-36, WOMAC, Hip Harris, Postel-D'Aubigne scores; and on postoperative transfusion rates. T-tests, Chi-Square, MANCOVA (age, ethnicity, BMI, and preoperative-diagnosis adjustments) were used. Mean follow-up: 3 years. Alpha was set at 0.05.

At baseline and compared to Whites, African-Americans were significantly younger (mean, 67 vs. 59 years), had fewer Hispanics (61% vs. 26%), and had higher BMI (28.5 vs. 30.6 Kg/m2) (all p≤0.048), respectively. Preoperative diagnoses were significantly different (p<0.001). There were no significant differences between the groups on preoperative scores after adjusting for confounders. Postoperatively, SF-36 bodily-pain (70 vs. 57), SF-36 mental-component-summary (56 vs. 53), WOMAC-total (5 vs. 12), and WOMAC-stiffness (0.14 vs. 0.57) were significantly worse in African-Americans (all p≤0.043), respectively. African-Americans underwent more transfusions (28% vs. 65%, p=0.001).

Compared to Whites, African-Americans underwent THA earlier in life, with higher BMI, and different preoperative-diagnosis. They also had worse postoperative scores and more transfusions. Race seems to be strongly associated with outcomes.
