Sažetak
Background: Croatian haemovigilance report includes transfusion reactions, trans- fusion events and reactions, and donor complications. Aims: To present results of haemovigilance in Croatia in 2011. Methods: Data from all Croatian institutions performing transfusion treatment are collected and processed at Department of Haemovigilance – Systematic Surveillance of Transfusion Treatment (SSTT) at Croatian Institute of Transfusion Medicine. Reac- tions and events are classified according to the Serious Hazards of Transfusion (SHOT) classification. Due to incomplete data on the number of transfused units, ‘number of units issued for transfusion treatment’ is used as a denominator to pres- ent the frequency of reactions to transfusion treatment. Reactions related to blood donation are classified according to the Standards for Collecting and Reporting Data on Reactions Related to Blood Donation (European Haemovigilance Network and International Society of Blood Transfusion, 2008) and their frequency is expressed per number of blood units collected. Results: In 2011, a total of 101 561 blood products were issued and 314 transfusion reactions (1.04/1000 blood products issued for transfusion treatment) reported from 36 Croatian institutions performing transfusion treatment. On reassessment of reac- tion reports at SSTT, 20 reactions were evaluated as severe adverse reactions, which included 10 DHTR, 5 anaphylactic reactions, 4 TACO and 1 possible TRALI. Three hundred adverse events were reported from 11/37 institutions included in the sur- veillance of adverse events associated with collection, processing, storage, distribu- tion and use of blood products. On reassessment of reports at SSTT, 63 events were evaluated as serious adverse events. According to the type of event, there were 6 product errors, 9 equipment failures, 14 ‘other’ events and 34 human errors includ- ing transfusion of erroneous blood product in seven cases, where no transfusion reactions were reported. Other errors were identified on time, before transfusion, and could be characterized as ‘near-miss’ events. In 12 of 13 institutions having submit- ted their reports, 175 808 donations (whole blood and apheresis) were collected and 2206 donation reactions and complications (1.25/1000 donations) reported. Summary: Data processing revealed the lack of uniformity among the institutions in reporting transfusion reactions and events, which is the result of understatement of the existing legal provisions and incomprehensive requirements where, among others, the terms ‘relation to transfusion’ and/or ‘severity of reaction’ are inade- quately explained. Consequently, the definitions of reaction and event are variedly interpreted, while data on investigating the cause of reaction and the level of suspi- cion of its association with transfusion are incomplete, thus hampering evaluation and categorization of the reactions/events. All this calls for amendments of the existing regulations. In addition, continuous education on haemovigilance is needed for all those involved in the transfusion chain to understand the risks associated with transfusion treatment and the importance of reporting reactions/events cor- rectly, thus contributing to upgrading the overall transfusion process.
