All EU member states are obliged to fulfill the requirements of Directive 2012/25/EU on reporting and handling of Serious Adverse Events (SAE) and Serious Adverse Reactions (SAR) in the field of organ donation and transplantation.
Eurotransplant offers a SAE/R handling service to all its member states.

Definition of a SAE/R


A Serious Adverse Event (SAE) is defined as any undesired and unexpected occurrence associated with any stage of the chain from donation to transplantation that might lead to the transmission of a communicable disease, to death or life-threatening, disabling or incapacitating conditions for patients or which results in, or prolongs, hospitalization or morbidity.

Events could be:

  • Malignancies found in the donor after transplantation
  • Match relevant virology changes after matching
  • HLA changes
  • Blood group changes

Potential damage could be:

  • Organ loss
  • Organ rejection
  • Prolonged hospital stay


A serious adverse reaction (SAR) is defined as an unintended response, including a communicable disease, in the living donor or in the recipient that might be associated with any stage of the chain from donation to transplantation that is fatal, life-threatening, disabling, incapacitating, or which results in, or prolongs, hospitalization or morbidity.

Reactions could be:

  • Malignancies
  • Infectious diseases
  • Allergies
Services of Eurotransplant

The handling procedure for SAE/R has been developed by Eurotransplant with the help and guidance of the Eurotransplant Organ Process Chain Committee (OPCC) which is as follows:

  • Eurotransplant sends a SAE/SAR form to the reporting organization
  • Eurotransplant collects all necessary information to prepare a report
  • Eurotransplant informs the NCA, delegated body and involved transplant-and donor centers
Directive 2012/25/EU

In Directive 2012/25/EU which is issued by the European Commission, information procedures for the exchange of human organs intended for transplantation between member states have been defined.
