Black and Hispanic patients with osteoarthritis have more pain and worse function than Whites at the time of arthroplasty. Whether this is true for patients with rheumatoid arthritis (RA) is unknown. This cross-sectional study used data on RA patients acquired between October 2013 and November 2018 prior to elective total knee (TKA) or hip arthroplasty (THA). Pain, function, and disease activity were assessed using the visual analogue scale (VAS), the Multidimensional Health Assessment Questionnaire (MDHAQ), and the Disease Activity Score (DAS28-ESR). We linked the cases to census tracts using geocoding to determine the community poverty level. Race, education, income, insurance and medications were collected via self-report. Using multivariable linear and logistic models we examined whether minority status predicted pain, function and RA disease activity at the time of arthroplasty. Thirty seven (23%) of the 164 patients were Black or Hispanic (minorities). The MDHAQ and DAS28-ESR were not significantly worse while VAS pain score was significantly worse in minority patients (p = 0.03). There was no significant difference in education between the groups. Insurance varied significantly; 29% of minority patients had Medicaid vs. 0% of Whites (p < 0.0001). In the multivariable analyses minority status was not significantly associated with DAS28-ESR [p = 0.66], MDHAQ [p = 0.26], or VAS pain [p = 0.18]. For Black and/or Hispanic patients with RA undergoing THA or TKA at a high-volume specialty hospital, unlike Black or Hispanic patients with osteoarthritis (OA), there was no association with worse pain, function, or RA disease activity at the time of elective arthroplasty.

接受全膝关节或全髋关节置换术的类风湿关节炎患者术前疼痛、功能和疾病活动的种族差异：一项基于纽约的研究

患有骨关节炎的黑人和西班牙裔患者在关节成形术时比白人有更多的疼痛和更差的功能。这对于类风湿关节炎 (RA) 患者是否属实尚不清楚。这项横断面研究使用了 2013 年 10 月至 2018 年 11 月期间在选择性全膝关节 (TKA) 或髋关节置换术 (THA) 之前获得的 RA 患者的数据。使用视觉模拟量表 (VAS)、多维健康评估问卷 (MDHAQ) 和疾病活动评分 (DAS28-ESR) 评估疼痛、功能和疾病活动。我们使用地理编码将案例与人口普查区联系起来，以确定社区贫困水平。通过自我报告收集种族、教育、收入、保险和药物。使用多变量线性和逻辑模型，我们检查了少数民族状态是否预测疼痛，关节成形术时的功能和 RA 疾病活动性。164 名患者中有 37 名（23%）是黑人或西班牙裔（少数民族）。少数患者的 MDHAQ 和 DAS28-ESR 没有显着恶化，而 VAS 疼痛评分显着恶化（p = 0.03）。各组之间的教育没有显着差异。保险差异很大；29% 的少数族裔患者有 Medicaid，而白人为 0% (p < 0.0001)。在多变量分析中，少数族裔状态与 DAS28-ESR [p = 0.66]、MDHAQ [p = 0.26] 或 VAS 疼痛 [p = 0.18] 没有显着相关性。对于在高容量专科医院接受 THA 或 TKA 的黑人和/或西班牙裔 RA 患者，与患有骨关节炎 (OA) 的黑人或西班牙裔患者不同，与更严重的疼痛、功能、
