A New Kidney Allocation Policy in Chile. Computer Based Simulation
Kidney allocation should reach a balance between equity and efficiency. In Chile kidneys are allocated based on ABO matching, first to medical priorities and then according to a point scheme considering human leukocyte antigen (HLA) match (60%), waiting list time (20%), and panel-reactive antibodies (PRA; 20%); pediatric recipients receive extra points. A new policy maintains ABO matching and medical priorities as the first step, but incorporates other successive steps: previous living donors donors, 0 mismatch, pediatric recipients, and finally all other recipients according to a point scheme incorporating recipient age, HLA match, PRA, and time on waiting list with similar proportions. We compared the resulting transplantations using the new versus the older allocation policy.
