Transplantation collaborative networks

The collaborative networks in Italy are described, with their objectives and the geographical areas covered. Their main features are: function of the reference centres, waiting lists, criteria for organ assignment, common programmes for some patients, services offered to the network members, organ procurement activity. The analysis of the activities performed included organ exchanges within and outside the network, common activities for tasks that could not be satisfactorily attained by a single centre or region, the collaborative studies. Finally, the role of the networks and of a national coordination, in order to better develop transplants nationwide, is discussed.
