Trauma-Associated Severe Hemorrhage Score Predicts Transfusion Needs

Description

Yucek et al developed the Trauma Associated Severe Hemorrhage (TASH) score for identifying trauma patients who are likely to require massive blood transfusions. This is a surrogate marker for life-threatening hemorrhage after multiple trauma. The authors are from the Polytrauma Study Group of the German Trauma Society.

Parameters:

(1) gender

(2) pelvic fracture

(3) femur fracture

(4) free intra-abdominal fluid on FAST examination

(5) heart rate in beats per minute

(6) systolic blood pressure in mm Hg

(7) hemoglobin in g/dL

(8) base excess in mmol/L

Parameter	Finding	Points
gender	female	0
	male	1
pelvic fracture	none	0
	clinically stable	0
	clinically unstable	6
femur fracture	none	0
	closed	0
	open and/or dislocated	3
free intra-abdominal fluid	absent	0
	present	3
heart rate in beats per minute	<= 120 beats per minute	0
	> 120 beats per minute	2
systolic blood pressure	< 100 mm Hg	4
	100 - 119 mm Hg	1
	>= 120 mm Hg	0
hemoglobin	< 7.00 g/dL	8
	7.00 to 8.99	6
	9.00 to 9.99	4
	10.00 to 10.99	3
	11.00 to 11.99	2
	>= 12 g/dL	0
base excess	< -10.00 mmol/L	4
	-6.01 to -10.00 mmol/L	3
	-2.01 to -6.00 mmol/L	1
	>= -2.00 mmol/L	0

where:

• It appears that only the worse femoral fracture gets scored if there is more than 1.

total TASH score =

= SUM(points for all 8 parameters)

Interpretation:

• minimum score: 0

• maximum score: 28

• Cutoffs of >=10 or >= 16 can be used.

• The higher the score the greater the likelihood of requiring massive blood transfusion.

X =

= (0.3 * (TASH score)) - 4.9

probability of requiring massive transfusion =

= 1 / (1 + EXP((-1) * X))
