Coagulapathy of Severe Trauma (COAST) Score of Mitra et al

Description

Mitra et al developed the COAST (Coagulopathy of Severe Trauma) score for identifying a trauma patient who may develop a coagulopathy. The patients are from the Alfred Hospital, Monash University, National Trauma Research Institute in Melbourne, Australia.

Patient selection: major trauma

Parameters:

(1) entrapment

(2) chest decompression (chest injury with foreign body in the thoracic cavity)

(3) systolic blood pressure in mm Hg

(4) temperature in °C

(5) injury to abdominal or pelvic cntents

Parameter	Finding	Points
entrapment	no	0
	yes	1
chest decompression	no	0
	yes	1
systolic blood pressure	>= 100 mm Hg	0
	90 to 99 mm Hg	1
	< 90 mm Hg	2
temperature	>= 35°C	0
	32 to 34.9°C	1
	< 32°C	2
injury to abdominal or pelvic contents	no	0
	yes	1

total score =

= SUM(points for all 5 parameters)

Interpretation:

• minimum score: 0

• maximum score: 7

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

Performance:

• A score >= 3 had a sensitivity of 60% and specificity of 96%, with an area under the ROC curve of 0.83. 93% of patients were correctly classified.
