The 'blood group O problem' in kidney transplantation--time to change?

Abstract

The export of blood group O donor kidneys to other blood groups leads to longer waiting times, to a higher death rate and to accumulation of blood group O patients on the waiting list, which will further aggravate the problem in the future. Our results should prompt further research on the issues associated with blood group O. Current allocation systems and living donor kidney exchange programmes should be re-evaluated to address this problem.
