improve safety for blood donors and transfusion recipients through promoting and supporting haemovigilance systems

Haemovigilance (HV) comprises surveillance procedures covering the whole transfusion chain from collection of blood (components) to follow-up of its recipients. It assesses information on undesirable transfusion effects to prevent their occurrence. This includes local venepuncture accidents, iron depletion, graft vs. host disease and mild to severe transfusion reactions. The HV definitions aim to standardize and report all these events in order to improve blood safety.


The WP focuses on both recipients and donors. We develop definitions and tools and share and compare data. We regularly discuss updates on international activities and work on definitions and tools. We collaborate with HV organisations across the world.

Our Chairperson is Kevin Land.




We meet at the ISBT congresses and develop HV definitions and tools. We also participate in international projects and have regular discussions with other Working Parties.

Joining the WP

Any professional who is actively involved in HV at any level is able to join this WP. Pharmaceutical company employees are able to join only if they contribute from a technical and scientific point of view, are transparent about their affiliation and do not promote any products.

Interested in joining the Haemovigilance WP? Please email our Chairperson.
