Overall, black Americans offer living kidney donations more frequently than do white Americans, researchers found.
Compared with white patients, black patients had a 20% higher incidence rate ratio for living kidney donation (95 percent CI 1.17-1.24), which varied by income quintile, according to Jagbir Gill, MD, of the University of British Columbia's St. Paul's Hospital in Vancouver, Canada, and colleagues.
Although blacks at the lowest income quintile had lower rates of donation than whites (IRR 0.84, 95% CI 0.78-0.90), those in the three highest earning quintiles had higher rates of donation than whites by 31% (95% CI 1.22-1.41), 50% (95% CI 1.39-1.62), and 87% (95% CI 1.73-2.02) at quintiles three, four, and five, respectively, they wrote in the Journal of the American Society of Nephrology.
End-stage renal disease (ESRD) patients may benefit more from live donor kidney transplantation due to the timeliness of the transplantation and superior outcomes. Prior research has looked at transplant recipient disparities, but has not measured donor-side disparities.
