Predicting the need for a mass hemorrhage protocol (MHP) activation is important both for individual patient outcome as well as for proper utilization of critical resources such as blood products and healthcare workers time and effort. These two studies look at using the RABT score to predict the need for mass transfusion. The RABT score is:
A 4-point score
blunt (0)/penetrating trauma (1),
shock index (hr/SBP)≥ 1 (1),
pelvic fracture (1)
FAST positive (1)
With a score >2 predictive of needing MHP.
These studies (one in Canadian trauma centers, the other in US trauma centers) validate the use of this score to predict the need for activation of a mass hemorrhage protocol.
