The first data of hemovigilance: Appraised from a single center in Bangladesh

Abstract

Background and Objectives: Hemovigilance is a prime requirement for safe transfusion practice rather it may be the reflection of laboratory performance in a blood bank. This study is the first report of transfusion errors and adverse reactions recorded in Bangladesh. It is a new approach to collect and analyze the data pertaining to issues associated with blood transfusion in the day care. This study is aimed to perceive the frequency of adverse reactions and the errors associated with its barrier. Methods: This cross-sectional observational study was conducted in the daycare unit of the Department of Transfusion Medicine of Bangabandhu Sheikh Mujib Medical University from July 2018 to June 2019. Any error regarding pretransfusion and transfusion procedure and adverse event following transfusion was noted according to departmental standard operating procedure and collected data were analyzed with Microsoft Excel 2016. Results: Of the 10,762 units of blood component selected for the issue to 6995 patients, 66 units were discarded. For various reasons. Out of 10696 units of blood component transfused, a total of 459 (4.29%) transfusion reactions were observed among which 390 (3.6%) were acute and 69 (0.6%) were delayed. Mild allergic (40.5%) and Febrile nonhemolytic (36.4%) were the most common acute reaction whereas alloimmunization (9.4%) and delayed hemolysis (4.1%) were the most observed delayed transfusion reaction. Among the recipient, transfusion reactions were observed slightly more in males (7.5%) than in females (5%) and the most affected age group was 20–29 years. Conclusion: However, it is not always possible to analyze the relevance of all the transfusions and the outcome of the patient. Now, a developing country like Bangladesh has to face and notify the errors and to solve them in parallel.
