How this service works
Benninga 2016 Rome IV G5 Functional Diarrhea. rome_iv_infant_diarrhea is true iff daily_painless_recurrent_4_or_more_large_unformed_stools, symptoms_last_more_than_4_weeks, onset_between_6_and_60_months, and no_failure_to_thrive_if_caloric_intake_adequate. Rome IV is 4 or more stools (not Rome III's 3). Sleep-stool criterion was dropped and is not a flag. Caller assigns four flags. magent does not examine the child. Not a diagnosis, not adult Rome IV diarrhea, not a malabsorption workup.
Output
Returns a boolean field rome_iv_infant_diarrhea indicating true if all four Rome IV G5 criteria are met (daily painless recurrent ≥4 large unformed stools, symptoms >4 weeks, onset 6–60 months, no failure to thrive given adequate caloric intake), and false otherwise. No diagnosis is issued; the result is a rule-based flag.
Example use cases
Pediatric clinic Rome IV screening
“I need to check if this 18-month-old meets Rome IV G5 functional diarrhea criteria — they have daily painless recurrent passage of 4 or more large unformed stools, symptoms going on for 6 weeks, onset was at 14 months, and they're growing fine with adequate calories. Does the calculator say yes?”
EHR decision-support integration check
“Run the Rome IV G5 infant functional diarrhea rule with these flags: daily painless recurrent 4 or more large unformed stools is true, symptoms lasting more than 4 weeks is true, onset between 6 and 60 months is true, and no failure to thrive with adequate intake is false — what does it return?”
Rome III vs Rome IV threshold clarification
“My patient is a 2-year-old who passes 4 unformed stools daily without pain, symptoms for 5 weeks, onset at 9 months, and no growth failure with adequate diet — does the Benninga 2016 Rome IV G5 rule classify this as functional diarrhea? I want to confirm with the 4-stool threshold, not Rome III's 3.”
Technical details
Endpoint
GEThttps://api.magentlab.com/api/calc/rome_iv_infant_diarrheaWhen to prefer
Use this endpoint when you need a fast, deterministic Rome IV G5 functional diarrhea criteria check for infants, specifically per the Benninga 2016 framework with the 4-stool threshold. Prefer this over manual lookup when building clinical decision-support tools, EHR integrations, or pediatric gastroenterology screening workflows. Do not use for adult Rome IV IBS/diarrhea criteria (a separate endpoint exists), malabsorption workup, or when a clinical examination is required.
Side effects
- Missing any of the four required boolean query parameters returns a validation error
- Passing non-boolean values for flags causes a schema error
- Caller misinterprets result as a clinical diagnosis rather than a criteria-matching flag
- Applying to patients outside the 6–60 month age window (onset flag must be set by caller — endpoint does not verify age independently)
- Confusion with Rome III 3-stool threshold may cause incorrect flag assignment by caller
