How this service works
PECARN pediatric IAI (Holmes 2013). Very low risk of IAI requiring acute intervention only when all seven caller-assigned findings are absent: abdominal wall trauma or seatbelt sign, GCS <14, abdominal tenderness, thoracic wall trauma, abdominal pain, decreased breath sounds, and vomiting. Presence of a criterion does not mandate CT. Not a diagnosis. Not PECARN head. magent does not examine the patient.
Output
Returns a boolean very_low_risk_iai_intervention flag: true only when all seven clinical predictor fields are false (absent), indicating very low risk of IAI requiring acute intervention per the Holmes 2013 PECARN rule. Returns false if any single criterion is present. Does not provide a diagnosis or CT recommendation.
Example use cases
Pediatric MVA seatbelt sign evaluation
“I have a 7-year-old who was in a car accident and has a seatbelt sign on the abdomen, no vomiting, no decreased breath sounds, GCS is normal (above 14), no thoracic wall trauma, and no abdominal tenderness or pain — run the PECARN IAI rule and tell me if they're very low risk.”
Blunt trauma CT avoidance screening
“Can you apply the Holmes 2013 PECARN IAI rule for a pediatric blunt trauma patient? The child has abdominal tenderness but no seatbelt sign, GCS is fine (not less than 14), no thoracic trauma, no vomiting, no abdominal pain complaint, and breath sounds are normal — is the very low risk flag met?”
All-negative findings low-risk confirmation
“My patient is a 10-year-old after a bike crash — no abdominal wall trauma, no seatbelt sign, GCS above 14, no abdominal tenderness, no thoracic wall trauma, no abdominal pain, no decreased breath sounds, and no vomiting. Use the PECARN IAI calculator to confirm if all seven findings are absent and the child is very low risk for intra-abdominal injury needing intervention.”
Technical details
Endpoint
GEThttps://api.magentlab.com/api/calc/pecarn_iaiWhen to prefer
Use this endpoint when you need a fast, structured implementation of the Holmes 2013 PECARN IAI seven-predictor decision rule for a pediatric patient after blunt abdominal trauma. Prefer it over manual lookup when automating clinical decision support workflows or when an agent needs a deterministic, auditable risk stratification signal. Do not use it as a standalone diagnostic or CT mandate tool, and do not confuse it with the PECARN head CT rule.
Side effects
- Missing any of the seven required boolean query parameters returns a validation error
- Passing non-boolean values for clinical flags causes a schema error
- Misapplying the rule to adults or head trauma (this is not PECARN head) yields incorrect clinical framing
- Network or payment authorization failure (402) if x402 payment is not properly handled
