Prehospital Prediction Model for Acute Traumatic Coagulopathy (PACT) of Peltan et al

Description

Peltan et al developed a score for predicting acute traumatic coagulopathy (ACT) based on prehospital variables. The authors are from the University of Washington in Seattle.

Patient selection: trauma

Outcome: acute traumatic coagulopathy (ACT) on admission (INR > 1.5)

Parameters:

(1) age of the patient, rounded to the nearest decade

(2) first prehospital shock index

(3) mechanism of injury

(4) Glasgow coma score (GCS)

(5) prehospital cardiopulmonary resuscitation (CPR)

(6) prehospital intubation or advanced airway

Parameter	Finding	Points
age		ROUND((age)/10,0)
first prehospital SI	<1	0
	>= 1	90
mechanism	motor vehicle, bicycle, motorcycle crash	0
	other	50
GCS		7 * (15 - (GCS))
prehospital CPR	no	0
	yes	120
prehospital intubation or airway	no	0
	yes	50

total score =

= SUM(points for all 6 parameters)

Interpretation:

• minimum age: around 2 (depends on age)

• maximum age: around 404 (depends on age)

• The higher the score the greater the risk for coagulopathy.

Performance:

• The area under the ROC curve is 0.74 to 0.80.

• A score >= 196 had a sensitivity of 0.73 and specificity of 0.74.
