Geographic Location May Help Explain Why Hispanics Face Disparities In Kidney Transplantation
Hispanics tend to have difficult-to-match blood types and to live in regions with limited organs for transplantation
In the United States, Hispanics with kidney failure are less likely than non-Hispanic whites to receive a kidney transplant largely due to their blood type and because of where they live, according to a study appearing in an upcoming issue of the Clinical Journal of the American Society of Nephrology (CJASN). The findings highlight the need to implement new deceased donor organ allocation policies that distribute organs over wider geographic areas to help reduce barriers to transplantation for Hispanics.
Among the major findings:
Hispanics were just as likely as non-Hispanic whites to be put on the kidney transplant waitlist.
Once waitlisted, Hispanics were 21% less likely to receive a transplant from a deceased donor. But this disparity was largely explained by differences in patient blood type and regional variability of organ supply among organ procurement organizations across the country.
"The main barriers after placement on the waitlist include the tendency for Hispanics to reside in regions with organ procurement organizations characterized by longer median waiting times as well as the higher likelihood for Hispanics to have blood type O, which further complicates organ allocations due to fewer ABO-compatible deceased donors," explained Dr. Arce. "To overcome the geographic disparities that Hispanics encounter in the path to transplantation, organ allocation policy revisions are needed to improve donor organ equity."
