🩸 TASH Score (Trauma Massive Transfusion)
Calculate the TASH score to predict the probability of massive transfusion in severe trauma from seven weighted parameters.
Clinical takeaway
≥ 16 points → massive transfusion probability > 50%.

When to use
Early prediction of massive transfusion need to trigger the massive transfusion protocol.
How it works
Weighted points from sex, SBP, HR, hemoglobin, base excess, FAST and complex long-bone/pelvic fracture (0–28). ≥ 16 corresponds to > 50% probability via logistic conversion.
Key points
- ≥ 16 points → massive transfusion probability > 50%.
- Use the official logistic calculator for an exact percentage.
- Predicts massive transfusion need, not simply whether to transfuse.

Worked calculation
The values below come from this tool's own example placeholders and are computed server-side with the formula shown on this page, so the arithmetic can be checked quickly. It demonstrates how to substitute values only — it is not clinical advice and not a real case.
| Sex | Male (1) |
|---|---|
| Systolic BP | 95 mmHg |
| Heart rate | 130 /min |
| Hemoglobin | 8.5 g/dL |
| Base excess | -7 mmol/L |
| FAST free fluid | Positive (3) |
| Complex long-bone / pelvic fracture | None (0) |
→TASH19
- Band：19 (0–28) → High probability (≥ 16, massive transfusion probability > 50%)
- Action：High MT probability: activate the massive transfusion protocol (fixed-ratio products ~ 1:1:1), hemostatic resuscitation, rapid definitive hemorrhage control
- Exact probability：TASH converts the score to a probability via a logistic function (≥ 16 ≈ > 50%). For an exact percentage use the official logistic calculator (e.g. MDCalc TASH); this tool gives the score and band, not a fabricated percentage
| Sex | Female (0) |
|---|---|
| Systolic BP | 95 mmHg |
| Heart rate | 130 /min |
| Hemoglobin | 8.5 g/dL |
| Base excess | -7 mmol/L |
| FAST free fluid | Negative/not done (0) |
| Complex long-bone / pelvic fracture | AIS 5 (6) |
→TASH21
- Band：21 (0–28) → High probability (≥ 16, massive transfusion probability > 50%)
