How this service works
Battle 2014 STUMBL integer score after blunt chest wall trauma: 1 point per decade of age starting at 10, 3 per rib fracture, 5 for chronic lung disease, 4 for preinjury anticoagulants, and 2 per 5% SpO2 decrease starting at 94%. Table 5 complication probabilities 13/29/52/70/80/88%. magent does not examine the chest or count ribs. Not a medical device, not a disposition or ICU order.
Output
Returns the computed STUMBL integer score derived from the Battle 2014 Table 4 formula, along with the corresponding complication probability tier from Table 5 (probabilities at thresholds: 13%, 29%, 52%, 70%, 80%, 88%).
Example use cases
Trauma bay complication risk triage
“My patient is 72 years old, has 6 rib fractures from a car accident, has COPD, is on warfarin, and their SpO2 is 91%. What is their STUMBL score and what complication probability does that correspond to?”
Comparing two chest trauma patients
“I have two patients — one is 45 with 2 rib fractures, no lung disease, no anticoagulants, SpO2 of 97%, and another is 58 with 5 rib fractures, chronic lung disease, on anticoagulants, SpO2 of 89%. Calculate STUMBL scores for both.”
Teaching case STUMBL walkthrough
“Walk me through the STUMBL score for a 55-year-old patient with 3 rib fractures, no chronic lung disease, no anticoagulants, and SpO2 of 94% — show the score and what complication risk percentage it maps to.”

Endpoint
GEThttps://api.magentlab.com/api/calc/stumblWhen to prefer
Use this endpoint when you need a fast, reproducible computation of the Battle 2014 STUMBL score for blunt chest wall trauma patients. It is ideal for clinical informatics workflows, EHR integrations, or triage support tools where the caller has already clinically assessed rib fractures and SpO2 and wants the score computed deterministically. It does not replace clinical examination and is not a medical device or disposition tool.
Side effects
- Missing required parameters (age, rib_count, chronic_lung_disease, preinjury_anticoagulants, spo2_percent) returns a 400 error
- Age out of range 1–120 or SpO2 out of range 50–100 returns a validation error
- rib_count outside 0–24 returns a validation error
- Non-integer values for integer fields return a schema validation error
- Network or payment failure (x402) returns a 402 Payment Required response
