How this service works
Mearin 2016 Rome IV IBS. rome_iv_ibs is true iff recurrent abdominal pain at least 1 day per week in the last 3 months, onset at least 6 months prior, and at least two of: related to defecation, change in stool frequency, and change in stool form. supporting_features_met is 0-3. Caller assigns five flags. magent does not examine the patient. Not a diagnosis, not Rome III, not IBS subtype.
Output
Returns a JSON object indicating whether rome_iv_ibs is true or false (criteria met or not) and supporting_features_met as an integer 0–3 reflecting how many of the three supporting feature flags were true. Not a clinical diagnosis and does not classify IBS subtype.
Example use cases
EHR-integrated IBS screening tool
“Run the Rome IV IBS check for this patient: weekly abdominal pain for the past 3 months, onset was 8 months ago, pain is related to defecation (true), associated with change in stool frequency (true), but no change in stool form (false). Does she meet the criteria?”
Clinical research cohort eligibility check
“I'm building a cohort of Rome IV IBS-positive patients — for this subject, pain occurs at least once a week in the last 3 months (true), onset was 7 months ago (true), not related to defecation (false), no change in stool frequency (false), but there is a change in stool form (true). Does he qualify?”
Gastroenterology triage decision support
“Does this patient satisfy Rome IV IBS criteria? He reports recurrent abdominal pain less than once a week in the last 3 months (false), with symptom onset only 4 months ago (false), pain related to defecation (true), change in stool frequency (true), and change in stool form (true).”
Technical details
Endpoint
GEThttps://api.magentlab.com/api/calc/rome_iv_ibsWhen to prefer
Use this endpoint when you need a fast, deterministic, auditable computation of Rome IV IBS criteria (Mearin 2016) from already-assessed clinical flags. Prefer it over manual rule-checking when integrating IBS screening into EHR workflows, research pipelines, or clinical decision support tools. It is not a substitute for clinical examination and does not produce Rome III results or IBS subtype classification.
Side effects
- Missing required query parameter causes validation error
- Non-boolean value for a flag causes schema rejection
- All five flags required; partial input returns error
- Payment failure (x402) if USDC not provided
- API returns result based solely on caller-supplied flags — incorrect flag assignment yields incorrect output
