Figure 1.
Distribution of organ travel distance. From top to bottom: (A) kidney-alone, (B) kidney-pancreas, and (C) pancreas-alone transplants. The figure illustrates several models of organ allocation that were simulated with concentric circle sizes for kidney and pancreas transplants, varying from a 500 NM circle to a 150 NM circle around the donor hospital. Various proximity point scenarios were also modeled, ranging from eight to 20, assigned linearly outside the circle edge and tapering to zero points at the maximum distance possible between the donor hospital and a transplant center. Various proximity point scenarios were also modeled, ranging from zero to four, assigned linearly inside the circle, and tapering to zero points at the maximum distance possible between the donor hospital and a transplant center within the circle. The naming convention refers to circle size for kidney-alone offers, circle size for kidney-pancreas and pancreas alone offers, maximum proximity points within the circle, and maximum proximity points outside the circle. The last two models on the extreme right have a single allocation circle, but all candidates within 150 or 250 NM, respectively, receive the maximum four proximity points. BL, baseline or existing policy; 250.250.2.4, new policy.
