| contents | Kidney Exchange Programs (KEPs) promote access to living donor trans- plantation for patients suffering from end stage renal disease. The HLA compatibility between transplant recipients and donors plays an important role when solving the matching problems occuring in KEPs. Compatibility defines the feasible solution space and often occurs in a weighted form in the objective function. Recently, the paradigms used to express HLA com- patibility have advanced substantially from antigens to alleles and eplets. We show how KEP effectiveness and equity vary with these three paradigms. The equity analysis focuses on ethnic inequities and the result confirm that moving from antigen to allele and eplet paradigms may enlarge inequities. We present new optimization models based on equity weighting that rem- edy ethnic inequities for all three paradigms without sacrificing access to transplant. |
