Evaluating a program to increase blood donation among racial and ethnic minority communities in New York City

Individuals with sickle cell disease (SCD), thalassemia, and leukemia often require frequent transfusion and run the risk of red blood cell (RBC) alloimmunization. To prevent alloimmunization or when alloimmunization is present, phenotype‐matched and antigen‐negative RBCs are transfused. To increase the probability of a phenotypic match, donors and recipients should share the same racial and/or ethnic background. Because the majority of patients with SCD are of African and Hispanic or Latino descent, a donor base of racial and ethnic minority donors providing an adequate supply of antigen‐negative RBC units that can be phenotypically matched is required to meet the needs of frequently transfused patients.
