Clinical use

This PedsCore page brings together clinical information, implementation status and available evidence for Pediatric Crohn Disease Activity Index. It is intended for Children and adolescents with Crohn disease. The tool belongs to Growth and nutrition and should be interpreted in the appropriate clinical context.

Interpretation and validation

Original 11-component PCDAI, range 0-100. Hematocrit and growth items are entered using the published categories to respect age/sex-dependent references. PedsCore reports the continuous score and adds contemporary context that ECCO-ESPGHAN 2026 uses PCDAI ≤10 as a clinical-remission target and a decrease ≥12.5 points as response.

PedsCore does not replace clinical judgement. Scores, rules and calculators are presented with evidence traceability and a visible implementation status.

Clinical review and maintenance

Implementation review and independent clinical review are shown separately. PedsCore does not attribute named reviewers or external endorsement without a public record supporting the claim. The repository preserves source, change and test history.

Editorial transparency

This page is part of an open-source project. Evidence level, implementation status, validation notes and sources are shown explicitly. It currently contains 3 catalog references. Content and calculation changes are reviewed through the public repository, automated tests and version traceability.

The absence of an active calculator is not a clinical recommendation: some tools remain reference-only while source, licensing, exact variant or validation still require review.

Each page lets you verify what is being assessed, which population the tool describes, whether local calculation is available, which limitations remain open and which references support implementation. This context matters when different publications, versions or adaptations share a similar name but are not interchangeable.
