Disparities Persist Among Hispanic Patients: Completing Evaluation, Waitlisting, and Receiving a Kidney Transplant.

Abstract

Background: Hispanic patients receive disproportionately fewer kidney transplants (KT) than non-Hispanic White (NHW) patients. In this observational study, we evaluated disparities in completing evaluation steps to KT among Hispanic patients.

Methods: Using medical records of Hispanic and NHW patients initiating evaluation at 4 transplant centers from January 2011 to March 2020, we performed sequential Cox models to compare Hispanic versus NHW patients reaching each step of the evaluation process until receiving a KT.

Results: Among all 5197 patients (Hispanic n = 2473; NHW n = 2724) initiating evaluation, Hispanic patients had 8% lower risk to be approved by the kidney pancreas (KP) committee than NHW patients (adjusted hazard ratio [aHR], 0.92; 95% confidence intervals (CI), 0.86-0.98; P = 0.015). Among 3492 patients approved by the KP committee, Hispanic patients had 13% lower risk to be waitlisted than NHW patients (aHR, 0.87; 95% CI, 0.81-0.94; P = 0.004). Among 3382 patients who were waitlisted, Hispanic patients had 11% lower risk than NHW patients to receive KT (aHR, 0.89; 95% CI, 0.81-0.97; P = 0.011). Among all patients initiating evaluation, Hispanic patients had a 16% lower risk than NHW patients to reach KT (aHR, 0.84; 95% CI, 0.76-0.92; P = 0.0002).

Conclusions: Our study found that disproportionately fewer Hispanic patients were approved by the KP committee, were waitlisted, and received a KT, particularly a living donor kidney transplant, than NHW patients. Closer oversight of the evaluation process may help patients overcome challenges in access to KT.
