How this service works
Hyams 2016 Rome IV H1c child rumination. rome_iv_child_rumination is true iff repeated_regurgitation_rechewing_or_expulsion_soon_after_meals, does_not_occur_during_sleep, not_preceded_by_retching, not_explained_by_another_condition_or_eating_disorder, and fulfilled_at_least_2_months. GERD-treatment failure and weekly frequency are not required. Manometry is not parsed. Caller assigns five flags. magent does not observe regurgitation. Not a diagnosis, not adult Rome IV rumination, not neonate G2.
Output
Returns a rome_iv_child_rumination boolean indicating whether all five Rome IV H1c criteria are simultaneously satisfied. True only when every flag is true; false if any single criterion is not met. No manometry interpretation, no severity score, and no adult Rome IV or neonatal G2 classification is provided.
Example use cases
Pediatric GI clinic intake screening
“I'm evaluating a 7-year-old in our GI clinic. She has repeated regurgitation with rechewing soon after meals (true), it doesn't happen during sleep (true), there's no preceding retching (true), no other condition or eating disorder explains it (true), and this has been going on for about 3 months so the 2-month threshold is met (true). Does she meet Rome IV H1c child rumination disorder criteria?”
EHR decision support integration
“For a patient chart note: repeated regurgitation rechewing or expulsion soon after meals = true, does not occur during sleep = true, not preceded by retching = false, not explained by another condition or eating disorder = true, fulfilled at least 2 months = true — run the Rome IV H1c child rumination algorithm and tell me whether criteria are met.”
Research cohort eligibility check
“I need to confirm Rome IV H1c eligibility for a study participant: regurgitation with rechewing or expulsion soon after meals is present (true), not during sleep (true), not preceded by retching (true), no other medical or eating disorder explanation (true), but symptoms have only been present for 6 weeks so the 2-month criterion is false — does this child qualify?”
Technical details
Endpoint
GEThttps://api.magentlab.com/api/calc/rome_iv_child_ruminationWhen to prefer
Use this endpoint when you need a fast, rule-based computation of the Rome IV H1c pediatric rumination disorder criteria (Hyams 2016) from five pre-assessed clinical flags. Prefer it over manual logic when integrating into clinical decision support pipelines, EHR automation, or research eligibility screening where reproducibility matters. Do not use for adult Rome IV rumination disorder, neonatal functional GI disorder G2, or cases requiring manometry interpretation.
Side effects
- Missing any of the five required boolean query parameters returns a validation error
- Passing non-boolean values for flag parameters causes a schema error
- Network or payment (x402) authentication failure returns a 402 Payment Required response
- Caller misclassifying clinical flags upstream leads to incorrect (but technically valid) boolean output
