The "Transplant-Euro-Computer-Network": a European medical information system

The paper provides an overview of the European Computer Network interconnecting Transplantation facilities (Organ Exchange Organizations, Tissue Banks, and Registries). Background, usage scenarios, technical concepts, and perspectives are outlined. The key functionalities supported are the European Waiting List of urgent patients, the double Registration Check (DRC) Procedure, and interpersonal messaging functions. The DRC is based on a biological identification using the patients HLA characteristics to guarantee the confidentiality and privacy of patient data in inter-organizational communications.
