An overview and comparison of haemovigilance reporting forms across six countries relative to the WHO template

Objectives Haemovigilance monitors, identifies, reports, investigates, and analyses adverse event near-misses and reactions related to transfusion and blood product manufacture. Methods This was an observational study in which we analyzed and compared the WHO haemovigilance template form for hospital and blood establishment haemovigilance reporting forms from Australia, Canada, India, New Zealand, South Africa, and the United States. All data from these reporting systems/forms was tabulated. The study analyzed data elements from each form, scoring them based on their presence in the WHO template and country forms. Higher scores indicated greater comparability and more comprehensive data collection. Results We identified 57 data fields in haemovigilance reporting forms from six countries and the WHO template, essential for collecting information on suspected transfusion products and reactions. The US FDA form has the most fields at 40 (70 %), followed by Canada with 33 (58 %) and India with 27 (47 %). New Zealand’s form has the fewest at 16 (28 %), followed by South Africa with 17 (30 %). Conclusions Effective haemovigilance systems require time and commitment to develop, often starting small and growing with stakeholder involvement. A straightforward reporting form, accessible to all, is crucial for success.
