Clinical use

This PedsCore page brings together clinical information, implementation status and available evidence for Visual Analogue Scale. It is intended for Children older than 8 years and adolescents able to self-report. The tool belongs to Pain and should be interpreted in the appropriate clinical context.

Interpretation and validation

Self-report VAS implemented as a 100-mm line: the distance from the no-pain anchor to the patient's mark is measured. PedsCore does not convert the VAS into a 0-10 NRS or impose universal severity categories.

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.
