where d is the distance between donor hospital and transplant center in NM. Multiply by 3 if KDPI >85 |
This table defines the final rating scales considered during the project and the attribute weights of 4 optimized continuous distribution policies. Continuous distribution policies prioritize transplant candidates for a particular donated organ according to a weighted average of rating scale subscores. The attribute weights are the weights used in the weighted average.
cPRA, calculated panel-reactive antibody; EPTS, expected posttransplant survival; KDPI, Kidney Donor Profile Index; NM, nautical miles.
