Revised Trauma Score (RTS) Calculator
x402
Revised Trauma Score (RTS) Calculator is a paid API for AI agents from api.magentlab.com, paid per call via x402, $0.005/call, status unknown (last checked 2026-09-15).
Computes the Revised Trauma Score (Champion 1989) from GCS, systolic blood pressure, and respiratory rate — returning coded values, T-RTS sum, and weighted RTS.

How this service works
Revised Trauma Score (Champion 1989): coded GCS, SBP, and respiratory rate (0-4 each), T-RTS as their sum (0-12), and weighted RTS = 0.9368·GCS + 0.7326·SBP + 0.2908·RR. Deterministic published arithmetic with citation. Not a triage order; not ISS; not the 1981 Trauma Score.
Output
Returns the coded value (0–4) for each of GCS, systolic BP, and respiratory rate according to Champion 1989 published bands; the T-RTS (their sum, 0–12); and the weighted RTS (0.9368 × coded GCS + 0.7326 × coded SBP + 0.2908 × coded RR). All arithmetic is deterministic and citation-grounded.
Example use cases
Trauma registry documentation scoring
“I need to score a trauma patient for the registry: their GCS was 10, systolic BP was 80 mm Hg, and respiratory rate was 8. Give me the full Revised Trauma Score including the coded bands and the weighted RTS.”
Prehospital triage severity classification
“Our paramedic team assessed a patient with GCS 14, systolic pressure 120, and respiratory rate 20 — can you run the Champion 1989 Revised Trauma Score and tell me the T-RTS and weighted score?”
Severe TBI physiologic scoring
“For a patient with GCS of 3, systolic blood pressure of 0, and respiratory rate of 0, what does the Revised Trauma Score look like — what are the coded values and what is the weighted RTS?”
Technical details
Endpoint
GEThttps://api.magentlab.com/api/calc/rtsWhen to prefer
Use this endpoint when you need a deterministic, citation-exact implementation of Champion 1989 Revised Trauma Score — not the original 1981 Trauma Score, not ISS, and not an AI-estimated triage order. Ideal for trauma registry documentation, research pipelines, or clinical decision support tooling where reproducibility and citation fidelity matter.
Side effects
- Missing required parameter (gcs, systolic_mm_hg, or respiratory_rate) returns a 4xx error
- GCS outside 3–15 range may return a validation error or unexpected coded value
- Systolic BP outside 0–300 or respiratory rate outside 0–80 may cause out-of-range errors
- Payment not included or insufficient (x402) results in a 402 Payment Required response
