SHOT conference report 2016: serious hazards of transfusion - human factors continue to cause most transfusion-related incidents

Transfus Med. 2016 Dec;26(6):401-405. doi: 10.1111/tme.12380.


The Annual SHOT Report for incidents reported in 2015 was published on 7 July at the SHOT symposium. Once again, the majority of reports (77·7%) were associated with mistakes ('human factors'). Pressures and stress in the hospital environment contributed to several error reports. There were 26 deaths where transfusion played a part, one due to haemolysis from anti-Wra (units issued electronically). The incidence of haemolysis due to this antibody has increased in recent years. Transfusion-associated circulatory overload is the most common contributor to death and major morbidity. Reports of delays to transfusion have increased, some caused by the failure of correct patient identification. There were seven ABO-incompatible red cell transfusions (one death) with an additional six to allogeneic stem cell transplant recipients. Near-miss reporting and analysis is useful and demonstrated nearly 300 instances of wrong blood in tube, which could have resulted in ABO-incompatible transfusion had the error not been detected. Errors with anti-D immunoglobulin continue, and preliminary data from the new survey of new anti-D found in pregnancy has shown that sensitisation occurs in some women even with apparently 'ideal' care. For the first time, the SHOT report now incorporates a chapter on donor events.

Keywords: SHOT; donor haemovigilance; haemovigilance; serious adverse events.
