How to participate?

Many haemovigilance systems collect their own national/local statistics for donor and recipient adverse reactions. While this data drives local policies, it is fragmented and not centrally collected. Increasingly there are requests to collate this data at an international level for decision-maker, researcher, and program staff use. 

 ISTARE, the International Surveillance database of Adverse Reactions and Events in donors and recipients of blood components, was created in 2008 to facilitate the sharing of best practices and benchmarking of HV data.  As of 2016, 125 annual aggregated national data sets have been received from 25 countries, covering 132.8 million blood components issued with 102,955 recipient adverse reactions and 594,477 donor adverse reactions reported.

 Long-term success of this project depends on regular submission of validated data from HV systems around the globe.  If you are interested in contributing HV data from your country or have questions about how a policy-maker or researcher might be able to utilize anonymized data, please email the IHN at for further information.
