How this service works
Hyams 2016 Rome IV H3b. rome_iv_child_fecal_incontinence is true iff developmental_age_older_than_4_years, duration_at_least_1_month, defecation_into_places_inappropriate_to_sociocultural_context, no_evidence_of_fecal_retention, and not_explained_by_another_condition. Item 2 is exclusion of fecal retention, not a symptom count. Duration is 1 month. Caller assigns five flags. magent does not examine the child. Not a diagnosis, not H3a functional constipation, not adult Rao 2016 F1.
Output
Returns a boolean rome_iv_child_fecal_incontinence indicating whether all five Rome IV H3b criteria are simultaneously satisfied: developmental age older than 4 years, duration at least 1 month, defecation into places inappropriate to sociocultural context, no evidence of fecal retention, and the condition not explained by another medical condition. All five must be true for the result to be true.
Example use cases
Pediatric GI clinic diagnostic screening
“I'm reviewing a 6-year-old patient in our GI clinic — developmental age is above 4, they've had inappropriate defecation for 6 weeks, no fecal retention on exam, and we've ruled out other conditions. Does this child meet Rome IV H3b criteria for non-retentive fecal incontinence?”
Ruling out fecal retention component
“My patient is a 5-year-old with soiling accidents for the past 5 weeks. The workup shows no evidence of fecal retention, defecation is in inappropriate places, developmental age is over 4, and no other medical explanation has been found. Can you run the Rome IV H3b H3b check to confirm this is non-retentive fecal incontinence and not H3a?”
EHR-integrated automated criteria check
“For this pediatric patient record: developmental age over 4 is true, duration at least 1 month is true, inappropriate defecation is true, no fecal retention is true, not explained by another condition is true — apply the Hyams 2016 Rome IV H3b algorithm and tell me if they qualify.”

Endpoint
GEThttps://api.magentlab.com/api/calc/rome_iv_child_fecal_incontinenceWhen to prefer
Use this endpoint when a clinician or clinical decision support agent has already assessed and assigned all five Rome IV H3b boolean flags for a pediatric patient and needs to compute whether the H3b (non-retentive fecal incontinence) criteria are met. Prefer over general clinical NLP or LLM-based reasoning when you need a deterministic, reference-faithful application of the Hyams 2016 Rome IV H3b algorithm. Do not use for adult Rome IV F1 fecal incontinence (Rao 2016), for H3a functional constipation, or when fecal retention has not yet been evaluated.
Side effects
- Missing any of the five required boolean query parameters returns a validation error
- Passing non-boolean values for flags causes schema rejection
- Conflating this endpoint with adult Rome IV F1 criteria (Rao 2016) leads to wrong algorithm selection
- Confusing H3b with H3a functional constipation — this endpoint excludes fecal retention cases
