Abbreviated disease-activity index for paediatric Crohn’s disease.
The PCDAI — Paediatric Crohn’s Disease Activity Index is a GI & Liver scoring tool used in paediatric practice. Abbreviated disease-activity index for paediatric Crohn’s disease. It scores 8 criteria and interprets the total across 3 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.
8. They are Abdominal pain; Stools per day; General wellbeing; Weight; Height (at diagnosis) or height velocity (follow-up); Abdomen on examination; and others.
The total is interpreted as: any score - Remission: pCDAI ≤10 - clinical remission (some authors use <10); 11 points or more - Mild: pCDAI 11-30 - mild disease activity; 31 points or more - Moderate-severe: pCDAI >30 - moderate to severe disease. Escalate therapy and involve paediatric gastroenterology.
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.
This is the abbreviated (clinical) PCDAI; the original also includes haematocrit, ESR and albumin.
Yes. Score definitions are bundled with the PediAid app, so the score computes without a connection.
