6 Years of shot reporting--its influence on UK blood safety

Abstract

Recognition of the importance of systematic surveillance of adverse effects of transfusion has led to the development of haemovigilance schemes [Faber JC. Haemovigilance around the world. Vox Sang 2002;83(suppl.1):71], of which the Serious Hazards of Transfusion (SHOT) scheme, launched in 1996, was one of the first. Over 90% of UK hospitals now participate in the scheme; in 6 years of reporting, SHOT analysed 1630 events of which 64% were errors in the transfusion process, leading to 193 instances of ABO incompatible transfusion. Transfusion related acute lung injury, bacterial contamination of platelets and transfusion-associated graft-versus-host disease were also identified as important preventable causes of mortality and morbidity. Data from SHOT has provided evidence to support the development of blood safety strategies in the UK.
