Stereotypical episodes of intense vomiting with well periods in between.
The Rome IV — Cyclic Vomiting Syndrome is a GI & Liver scoring tool used in paediatric practice. Stereotypical episodes of intense vomiting with well periods in between. It scores 4 criteria and interprets the total across 2 bands, so the number always arrives with the severity it implies rather than on its own. In PediAid each criterion is shown as a labelled option with the weight it carries, so the total can be checked rather than taken on trust.
4. They are ≥ 2 periods of intense, unremitting nausea and paroxysmal vomiting lasting hours to days, within a 6-month period; Episodes are stereotypical in each patient; Episodes are separated by weeks to months with return to baseline health; Symptoms cannot be attributed to another medical condition after appropriate evaluation.
The total is interpreted as: any score - Criteria not met: all four criteria are required for a Rome IV diagnosis of cyclic vomiting syndrome; 4 criteria or more - Criteria met: all criteria met - cyclic vomiting syndrome. Consider prophylaxis (cyproheptadine <5 y, amitriptyline ≥5 y, propranolol) and an abortive plan with early rehydration.
No. It is a structured way to record and communicate severity. A clinician concerned about a child should act on that concern regardless of the total.

Yes. Score definitions are bundled with the PediAid app, so the score computes without a connection.
