IHN is an international organisation comprised of national or regional haemovigilance systems. It serves as a forum for sharing best practice and benchmarking of data, as well as providing a resource for existing and new haemovigilance systems. IHN was formed in 2009 from the European Haemovigilance Network (EHN), which itself was founded in 1998.
The membership of the network consists of national, operational haemovigilance systems. These organisations join the group on behalf of their country, with a nominated lead member who is usually the head (director, president) of the national haemovigilance system of that country. Individuals working in haemovigilance from member countries are free to participate in all aspects of IHN.
The IHN provides a forum for sharing best practice and benchmarking of data, as well as providing a resource for existing and new haemovigilance systems. An annual symposium is held each year in one of the member countries and may be attended by interested professionals.
