Patient Blood Management Guidelines: Module 1 Critical Bleeding/Massive Transfusion

Under review

Module 1 Critical Bleeding/Massive Transfusion is under review.  This version was published in March 2011 and is based on the best available evidence published up to July 2009. The original version remains available to guide practice.                       



An updated draft Patient blood management guideline for people with critical bleeding was open for public consultation from 28 September 2022 to 9 November 2022. All submissions are being considered by the Clinical/Consumer Reference Group, which comprises representatives from specialist colleges, societies and organisations and the guideline will be updated accordingly. The draft guideline will also undergo an AGREE II assessment to confirm the methodological rigour and transparency in which it was developed.

Module 1 is intended to assist and guide health-care professionals in making clinical decisions when managing patients with critical bleeding who require or are likely to require massive transfusion.

Module 1 includes a Massive Transfusion Protocol (MTP) template that is designed to be adapted to meet local institutions’ patient population and resources.

Review and update of the PBM Guidelines

The NBA is currently considering the review and update process across the entire suite of modules rather than each module being updated in an isolated and iterative process. The aim is to transition to a sustainable and updateable methodology that will enable updates as the evidence base and clinical practice evolves.
