The Patient blood management guideline for adults with critical bleeding was published in 2023 (PDF and on MAGICapp). It is now under review and will be updated. Further information is available here.
This guideline provides clinical guidance for health professionals providing immediate in-hospital care for adults with critical bleeding, including the use of a major haemorrhage protocol (MHP) to guide the use of blood components, blood products and blood conservation strategies.
The clinical guidance is based on scientific evidence and consensus among clinical experts. The NBA gratefully acknowledges the dedication and expertise provided by the multidisciplinary Clinical/Consumer Reference Group (CRG).
In September 2025 a minor update was made to Good Practice Statement 5. This updated version of the guideline was published on 4 September 2025 in electronic format and on MAGICapp.
