Clinical use
This PedsCore page brings together clinical information, implementation status and available evidence for PECARN Febrile Infant Rule. It is intended for Febrile infants up to 60 days meeting published eligibility. The tool belongs to Pediatric emergency and should be interpreted in the appropriate clinical context.
Interpretation and validation
Local implementation of the 2019 PECARN rule for febrile infants ≤60 days. It uses the primary derived and validated version: negative urinalysis, ANC ≤4,090/mm³, and PCT ≤1.71 ng/mL, within the published eligible population.
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 1 catalog reference. 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.
