ERNICA is a network of expert multi-disciplinary professionals from specialised healthcare providers across Europe (‘ERNICA members’). ‘Affiliated partner’ hospitals (and their multi-disciplinary professionals) and ‘Associate partner’ patient organisations (and their ePAG advocates) also form part of the network. ‘Supporting Partners’ are healthcare providers, medical societies, and any other entity or individual which, without having a commercial relation with the ERNs and their Members or Affiliated Partners, or with the European Commission, contribute in different ways to the work of the network.
