Background: A2/A2B to blood group B kidney transplantation has improved transplant rates among disadvantaged blood group B patients with equivalent long-term graft outcomes. 18 months post-KAS, 82% transplant centers do not perform A2/A2BàB transplants (Figure 1). Methods: OPTN/UNOS Minority Affairs Committee (MAC) distributed a survey to all active US kidney transplant programs to identify best practices among participant centers and problems with implementation at non-participant centers. Results: 53 transplant centers (22.2%) responded with 24 (46.2%) participants in the A2/A2BàB provision. Common practices among participant centers included utilizing local hospital blood banks (58%) for isoagglutinin titer testing. Anti-A1 (43%), 1:8 acceptable titer cutoff for candidate eligibility (75%) was most common. Non-participant centers cited difficulty developing an A2/A2BàB protocol, including development of titer thresholds (32%) and an informed consent policy (21%) (Figure 2). A majority of non-participant centers (61%) stated that guidance for best practices would be helpful in A2/A2BàB participation. Conclusion: Underutilization of the A2/A2BàB provision under the new KAS remains with a sense that center protocol development is a major impediment to A2/A2BàB participation. Based on these findings, OPTN/UNOS MAC aims to provide best practice guidelines in an effort to increase A2/A2BàB center participation.
