How this service works
Yücel 2006 TASH (Trauma Associated Severe Hemorrhage): seven independent nested less-than point bands for arrival SBP, hemoglobin, intra-abdominal fluid, complex long-bone/pelvic fracture AIS, heart rate, base excess, and male sex; max 28. Highest matching band only (do not stack). Deterministic published arithmetic with citation; not a transfusion or MTP order; not ABC (assessment of blood consumption). Caller assigns FAST and AIS; magent does not read imaging.
Output
Returns the computed TASH total score (0–28) along with the individual band score for each of the seven parameters (SBP, hemoglobin, intra-abdominal fluid, fracture AIS, heart rate, base excess, sex). Each parameter reflects only the highest matching nested band per the Yücel 2006 published algorithm. The score is deterministic arithmetic and is not a transfusion order or MTP activation.
Example use cases
Trauma bay massive transfusion triage
“I have a male trauma patient arriving with SBP 85, HR 140, hemoglobin 6.8 g/dL, base excess -12, positive FAST, and a complex femur fracture graded AIS 3 — what is his TASH score?”
ED hemorrhage risk stratification
“Can you compute the TASH score for a female patient with systolic BP 115, heart rate 118, hemoglobin 9.2 g/dL, base excess -4, no intra-abdominal fluid on FAST, and no significant long bone or pelvic fractures?”
Retrospective trauma audit scoring
“I'm reviewing a trauma case: male patient, arrival SBP was 98, HR 125, hemoglobin 10.5 g/dL, base excess -3, FAST negative, pelvic fracture AIS 5 — please give me the TASH score so I can document the hemorrhage risk at presentation.”
Technical details
Endpoint
GEThttps://api.magentlab.com/api/calc/tashWhen to prefer
Use this endpoint when you need a deterministic, citation-backed TASH score per the Yücel 2006 paper and the caller is supplying pre-assigned FAST results and AIS values. Prefer this over ABC (Assessment of Blood Consumption) when you have lab values (hemoglobin, base excess) available. Do not use this as a substitute for MTP activation orders or transfusion decisions — it is a scoring aid only.
Side effects
- Missing required parameters (systolic_mm_hg, intra_abdominal_fluid, fracture_ais, heart_rate_bpm, base_excess_mmol_l, sex) returns a validation error
- Supplying both hemoglobin_g_l and hemoglobin_g_dl simultaneously returns an error
- fracture_ais value not in {0, 3, 4, 5} returns a validation error
- Out-of-range vitals (e.g. heart rate outside 30–220, SBP outside 0–300) return a validation error
- Payment not attached or insufficient USDC returns HTTP 402
