This document is intended to serve as a structured tool to facilitate a timely switch to group-specific red cell components in major haemorrhage (MH) situations. This will help optimise safety at various steps in the transfusion pathway and avoid unnecessary use of emergency blood components.
Serial Annual SHOT Reports have highlighted avoidable delays in provision of appropriate transfusion support in cases of major haemorrhage (MH) as well as avoidable use of Group O red cell components. These are valuable in emergencies but with limited supply, prompt switch to group specific red cells is recommended in MH protocol activations. Regular review of local policies and practices to ensure alignment with national guidelines is recommended. Adequate staff training and regular competency assessment is vital to ensure effective and safe transfusion practice.
