Trauma Associated Severe Hemorrhage (TASH) Score

Description

Calculates the TASH Score to predict the probability of needing a massive transfusion (>= 10 units of packed red blood cells) in trauma patients. The score uses seven independent variables available early in the trauma room.

Usage

tash_score_trauma(systolic_bp, hemoglobin, fast_positive, complex_fractures,
                  heart_rate, base_excess, sex)

Arguments

systolic_bp	Numeric. Systolic blood pressure in mmHg. <100: +4 pts. 100-120: +1 pt. >120: 0 pts.
hemoglobin	Numeric. Hemoglobin level in g/dL. <7: +6 pts. 7-<9: +4 pts. 9-<11: +3 pts. 11-<12: +2 pts. >=12: 0 pts.
fast_positive	Numeric (0 or 1). Positive Focused Assessment with Sonography for Trauma (FAST) for intra-abdominal fluid. (1 = Yes, +3 pts).
complex_fractures	Numeric (0 or 1). Presence of clinically unstable pelvic fracture or open/dislocated femur fracture. (1 = Yes, +3 pts).
heart_rate	Numeric. Heart rate in bpm. (>120: +2 pts).
base_excess	Numeric. Base excess in mmol/L. <-10: +4 pts. -10 to <-6: +3 pts. -6 to <-2: +1 pt. >=-2: 0 pts.
sex	String. Patient sex ("Male" or "Female"). (Male: +1 pt).

Value

A list containing:

TASH_Score	The calculated total score (Range 0-28).
Probability_Massive_Transfusion	The estimated probability of requiring massive transfusion based on the score.

Examples

# Example 1: High Risk
# SBP 90 (4), Hb 8 (4), FAST+ (3), Pelvic Fx (3), HR 130 (2), BE -8 (3), Male (1)
# Score = 20
tash_score_trauma(90, 8, 1, 1, 130, -8, "male")

# Example 2: Low Risk
# SBP 130 (0), Hb 13 (0), FAST- (0), No Fx (0), HR 90 (0), BE 0 (0), Female (0)
# Score = 0
tash_score_trauma(130, 13, 0, 0, 90, 0, "female")
