December 2020 update: The final guidance is now available here (see also the links at bottom of page)

The national critical haemorrhage project aims to reduce mortality and associated multi-organ failure from critical haemorrhage caused by trauma.

Working with the sector and trauma experts we will develop national best practice guidance that, when adjusted for local context and scale, supports ambulance services, emergency departments (EDs), intensive care units (ICUs) and perioperative teams to recognise critical haemorrhage and act accordingly. Internationally, best practice in this area has been shown to reduce mortality, improve service quality and reduce cost.

An expert reference group will advise on development of the guidance. Engagement with district health boards will begin in early 2020 and publication is intended for September 2020.

Dr Kerry Gunn has been appointed clinical lead for the project. Kerry is an anaesthetist with a special interest in coagulopathy and massive haemorrhage management. He chaired the Auckland Blood Transfusion Committee and is a member of the steering committee for the Patient Blood Management Committee of the National Blood Authority (Australia) and the Australasian Massive Transfusion Registry. He is also a member of the Commission’s Perioperative Mortality Review Committee.

The network’s clinical lead and programme manager are also involved in the project.
