title: It takes six to boogie: allocating cadaver kidneys in Eurotransplant.
abstract: In March 1996, a new allocation point system for cadaver kidneys, the Eurotransplant (ET) Kidney Allocation System (KAS), was introduced in ET, the first multinational organ exchange organization. The aims of ETKAS were to reduce average and maximum waiting time, to allow patients with rare human leukocyte antigen (HLA) phenotypes or combinations to receive an "optimal" offer, to keep the exchange rates between the participating countries balanced, and finally to keep optimal graft survival, by means of HLA matching. Elderly patients and highly sensitized patients profit in addition from special programs, the ET Senior Program and the Acceptable Mismatch Program, respectively. All kidneys are offered to the pool and are allocated according to the degree of HLA matching, mismatch probability, waiting time, distance from the donor center, and balance between the countries participating in ET. A summary of 6 years' experience with the ETKAS is presented in this article.
