Abstrakt:	Importance: There are over 2 million undocumented immigrants (UI) in California, where currently, all individuals regardless of immigration status have access to kidney transplant. There is a medical perception that UI face a higher risk of transplant failure due to language barriers and lack of access to immunosuppressive medication and health care when compared with US residents (UR). Objective: To elucidate the kidney transplant outcomes of UI at an academic medical center in California. Design, Setting, and Participants: A retrospective cohort study was conducted from a single transplant center during an 8-year study period. Patients who received a kidney transplant at the University of California, Irvine, between January 1, 2012, and September 1, 2019, were included in this study. Data were analyzed from October 2020 to August 2021. Exposures: The primary exposure of this study was citizenship status. UI were defined as immigrants residing in the US without permission or legal documentation. Main Outcomes and Measures: The primary end point was all-cause graft loss defined as the return to dialysis, need for a second kidney transplant, or death. The secondary end points of this study were all-cause mortality and rejection. All-cause mortality between the 2 groups was compared using multiple Cox proportional hazard regression analysis. Other transplant outcomes, including all-cause graft loss and acute rejection, were examined by competing risks regressions with mortality and mortality plus graft loss serving as competing risks, respectively. Results: Of all 446 consecutive kidney transplant recipients, the mean (SD) age was 47 (13) years; 261 patients (59%) were male, and 114 (26%) were UI. During a median (IQR) follow-up time of 3.39 (0.04-8.11) years, 6 UI and 48 UR experienced all-cause graft loss. UR had a 192% (hazard ratio, 2.92; 95% CI, 1.21-6.85; P = .01) and 343% (hazard ratio, 4.34; 95% CI, 1.05-18.69; P = .04) significantly increased unadjusted risk for all-cause graft loss and all-cause mortality, respectively. These results became nonsignificant and were mostly attenuated when adjusted for age and ethnicity. Finally, there was no difference in incidence rate of kidney allograft rejection between the 2 groups (UR, 3.5 per 100 person-years vs UI, 2.4 per 100 person-years; rate ratio, 1.45; 95% CI, 0.90-5.05; P = .08). Conclusions and Relevance: This single-center cohort study found that kidney transplant outcomes of UI were not inferior to those of UR. Across the US, however, UI have consistently had unequal access to transplantation. These findings suggest that extending kidney transplants to UI is safe and does not portend worse outcomes. As a result, denying transplant according to immigration status not only results in higher costs but also worse end stage kidney disease outcomes for an already underserved population.
