The donor hemovigilance should include reporting of unexpected adverse events in whole blood and component donors and the action taken as a result. These events may be adverse reactions or complications resulting from donation, selection, and management of donors, which may directly harm the donor or influence the quality of the product, thereby putting the recipient at risk.[6
] A joint working group from the ISBT and EHN has proposed a classification and a set of definitions of complications related to blood donation.[6
In this issue of Asian Journal of Transfusion Science, there are interesting manuscripts focusing on different aspects of hemovigilance. Jeongeun et al., in their paper on code development of national hemovigilance system, concluded that few major categories could be added to the blood transfusion safety stages. Through their study, they could suggest expansion strategies of hemovigilance systems for hospital blood banks. In yet another manuscript by Agnihotri et al., there is an analysis of adverse events and predisposing factors in whole blood donors. They also concluded that analysis of adverse events helps in identifying the blood donors at risk of donor reactions and adopting appropriate donor motivational strategies.
Among the Asian countries, a well established hemovigilance system is lacking and there is paucity of data on hemovigilance except for Japan, which has published report on adverse reaction and infectious diseases (http://www.jrc.or.jp/vcms_lf/haemovigilanceannualreport1993-2001.pdf
). The goal of establishing hemovigilance system in India is already in place under the National Blood Policy.[7
] National Blood Transfusion Council will take a lead in developing the program with assistance of Technical Resource Group and a monitoring committee.
In order to have a well organized hemovigilance system in developing countries like India, a comprehensive approach is required. A streamlined mechanism for data collection using standardized tools at hospital level and good coordination at the national level can bring up effective hemovigilance system in a country. A functional hospital transfusion committee can act as backbone for this by developing policies for transfusion practices, appropriate documentation, reporting and investigation of transfusion reaction. In addition the draft recommendation on hemovigilance system by World Health Organization (WHO) may help in developing an efficient system in developing countries (http://www.bloodtransfusion.it/articoli/47/en/Doi%200010.pdf
). The data from a well functioning hemovigilance system can be used as quality indicator for monitoring the blood transfusion safety, and also contribute significantly to evidence-based transfusion medicine.
