Patients of racial minorities have lower chance of securing a suitable donor, essential part of successful allogeneic stem cell transplant. In this simulated interview study, we sought to examine how hematologists discuss donor options and risks with patients with high-risk myeloid neoplasm considering transplant. Thirty-seven US hematologists participated (65% male; 65% white, 24% Asian, none Black), randomly assigned to meet with a Black or white patient actor. The hematologists emphasized the benefits of a full match with the white patient and high chance of securing a donor. Conversely, with the Black patient, they tended not to ask about ancestry, discuss the donor registry, race implications or challenges with donor search. Knowing the patient had children, many recommended haploidentical transplant. The unique circumstances of transplant argue for a focused communication including discussing race. While conversations should be tailored to each patient, limiting essential information on donor options may contribute to disparities.
