TASH Score (Trauma Associated Severe Hemorrhage) Calculator

What is the TASH Score?

The Trauma Associated Severe Hemorrhage (TASH) Score is a validated tool used to predict the probability of massive transfusion in trauma patients. It was developed to help clinicians identify patients who may require massive transfusion protocols early in their care.

Clinical Significance

Early identification of patients who may need massive transfusion is crucial for improving outcomes in trauma care. The TASH Score helps emergency departments and trauma teams prepare blood products and activate massive transfusion protocols in a timely manner, potentially saving lives by reducing delays in blood product administration.

Components of the TASH Score

The TASH Score incorporates several clinical and laboratory parameters:

  • Hemoglobin level
  • Base excess
  • Systolic blood pressure
  • Heart rate
  • Positive FAST (Focused Assessment with Sonography for Trauma)
  • Clinically unstable pelvic fracture
  • Open or dislocated femur fracture
  • Male gender

Interpretation

The TASH Score ranges from 0 to 28 points. Higher scores indicate a greater probability of requiring massive transfusion:

  • Score ≤ 8: Low probability (<10%)
  • Score 9-12: Moderate probability (10-25%)
  • Score 13-16: High probability (25-40%)
  • Score ≥ 17: Very high probability (>40%)

Limitations

While the TASH Score is a valuable tool, it should be used as part of a comprehensive clinical assessment. The score may not account for all factors that influence bleeding risk, and clinical judgment remains essential. Additionally, the score was developed in a specific population and may perform differently in other settings.
