7.19 Adverse Event Data

The NZBS National Haemovigilance Programme has been collecting data regarding transfusion-related adverse events (TRAE) since 2005. The imputability scores of adverse events (a measure of how likely the event is due to transfusion) have been recorded since 2008. In 2021, a total of 335 events having an imputability score ≥3 were reported for transfusions involving 24,621 recipients who between them received 134,440 red cell, platelet or frozen plasma components. Table 7.3 outlines the type and frequency of TRAE during the period 2017 - 2021.
