Haemovigilance in Slovenia until the year 2010
Abstract
Background: A haemovigilance system makes it possible to identify critical points in blood transfusion chain from blood collection to the patient and to introduce new measures, thus creating conditions for better transfusion safety. Methods: Data on haemovigilance in Slovenia in years 2003–2010 were obtained from annual reports. The collected data were systematically and chronologically arranged, displayed in tables and analyzed using descriptive statistical methods. Results: From 2003 to 2010, there were 1,333 adverse reactions reported: 511 allergic, 25 anaphylactoid, 604 febrile nonhaemolytic, 22 haemolytic reactions, 4 TRALI, 69 TACO, 11 suspected transfusion-transmitted infections and 74 cases classified as others. From 2003–2010, 104 (7.8 %) reactions were considered severe. There are considerable differences among Slovenian hospitals as to the number of reports, ranging from 0.4 to 3.1 per 1,000 blood components issued in 2010. Severe adverse events were reported, such as wrong blood in test tubes and incorrect blood component transfused. There were also some severe adverse reactions reported during the collection of blood from donors, defective plastic blood bags, positive test results and adverse events during the storage and distribution of blood. Conclusions: The collected data are the foundation for the improvement of blood safety by implementing new technologies as well as continuous training of clinical and transfusion staff and optimal blood usage.Downloads
