Dharmasukrit C, Chan SYS, Applegate RL, et al. - This study was undertaken to investigate race/ethnicity as a potential moderator of the relationships of frailty and functional status with arthroplasty outcomes. Researchers evaluated The National Surgical Quality Improvement Program for patients who underwent total hip arthroplasty (THA) or total knee arthroplasty (TKA) from 2011-2017. The modified frailty index was applied to evaluate frailty. Associations connecting frailty/functional status with 30-day readmission, adverse discharge, and length of stay (LOS) were evaluated by conducting regression analyses. In the analysis, 219,143 TKA and 130,022 THA patients were distinguished in the analysis. The results of this study demonstrate that the disparities for BNH and Hispanic patients persist for readmission, adverse discharge, and LOS. Nevertheless, the impacts of elevating frailty and non-independent functional status on these outcomes were the most pronounced among White non-Hispanic patients.
