Assessment of blood consumption score

The Assessment of Blood Consumption tool is simple, and it turns out to be quite predictive. 

Here’s how it works. Assess 1 point for each of the following:

• Heart rate > 120
• Systolic blood pressure < 90
• FAST positive
• Penetrating mechanism

A score >=2 is predictive of massive transfusion. and to initiate the PRBCs:Plsama:Platelets 1:1:1 ratio

 In this small series, the sensitivity of ABC was 89% and the specificity was 85%. The overtriage rate was only 13%.

The investigators were satisfied enough with this tool that it is now being used to activate the massive transfusion protocol at the Mayo Clinic.

Bottom line: ABC is a simple, easy to use and accurate system for activating your massive transfusion protocol, with a low under- and over-triage rate.
