ERN-RND thrives from exchange of knowledge between our centres. In order to facilitate connection of our members in the expanding network, we need to know who our members are and what treasure of expertise they have to share. For example, this helps us organising eConsultations using the Clinical Patient Management System (CPMS), allowing to receive a second opinion on complex and unsolved cases from other experts across Europe. Thank you for completing this survey and for your committment to ERN-RND and cross-border healthcare!
