ABC_score_massive_transfusion v.1
Assessment of Blood Consumption (ABC) Score is used for early and rapid estimation of the need for massive transfusion in acutely injured patients, using four simple clinical and bedside criteria: penetrating mechanism of injury, arrival systolic blood pressure of 90 mmHg or less, arrival heart rate of 120 bpm or greater, and positive FAST (focused assessment with sonography in trauma). The presence of any variable contributes one point to the total score giving a minimum score of 0 and a maximum possible score of 4. A score of 2 or greater is likely to require massive transfusion. ABC score was the simplest and the quickest, but least accurate (13.1%), in an efficiency assessment of massive transfusion scoring systems, when compared with trauma associated severe haemorrhage (TASH) and emergency transfusion score (ETS).
To predict the need for massive transfusion of blood (and blood products) in acutely injured patients at initial assessment using simple clinical and bedside criteria.
To calculate the ABC score for massive transfusion based on presence or absence of component variables: penetrating mechanism of injury, arrival systolic blood pressure of 90 mmHg or less, arrival heart rate of 120 bpm or greater, and positive FAST (focused assessment with sonography in trauma), at initial patient assessment. The presence of any variable contributes one point to the total score giving a minimum score of 0 and a maximum possible score of 4. Individuals with a score of 2 or greater are likely to require massive transfusion.
The ABC score does not indicate if a patient should receive blood, only if they should receive blood through a massive transfusion protocol.
