Massive transfusion protocol prediction decision aids in an Australian trauma setting

Area of Science:

• Trauma care and emergency medicine
• Hemorrhagic shock management
• Clinical decision support systems

Background:

• Emergent massive transfusion protocols (MTPs) are critical for trauma patients.
• Existing MTP prediction decision aids lack extensive study in the Australasian region.
• Accurate prediction of MTP activation is essential for timely intervention.

Purpose of the Study:

• To evaluate the accuracy of commonly used MTP decision aids in an Australasian urban Level 1 trauma center.
• To assess the performance of specific MTP prediction scores in injured patients.
• To provide evidence for the utility of decision aids in the Australasian trauma setting.

Main Methods:

• Prospective enrollment of consecutive trauma patients into a registry.
• Utilisation of thromboelastogram (TEG) assays for trauma patient assessment.
• Analysis using receiver operating characteristic (ROC) curves, sensitivity, and specificity.

Main Results:

• 114 patients met inclusion criteria; 56 received MTP.
• McLaughlin and Larson scores demonstrated high specificity (>90%) for MTP prediction.
• The ABC score performed less accurately than anticipated, despite comparable Area Under the Curve (AUC) results to prior studies.

Conclusions:

• Available MTP prediction decision aids require cautious application in traumatic hemorrhage.
• Clinical judgment should complement the use of decision aids for optimal patient management.
• Further validation of MTP decision tools in the Australasian context is warranted.
