Reporting undesirable effects of transfusion (haemovigilance)

Haemotherapy often plays a crucial role in the medical treatment of patients and has contributed to medical progress. However, despite all the safety measures in the manufacture, testing and administration of blood and blood components, the occurrence of undesirable effects cannot be ruled out. The collection and evaluation of data on transfusion reactions and quality defects enables us to detect transfusion risks and develop recommendations to optimise haemotherapy.
