PEWS — Paediatric Early Warning Score

Bedside score to detect clinical deterioration on the ward

1 What is the PEWS — Paediatric Early Warning Score?

The Paediatric Early Warning Score is a bedside tool for spotting a deteriorating child on the ward before an arrest. It converts behaviour, cardiovascular and respiratory observations into a single number, with escalation attached to bands rather than to any single abnormal observation.

2 When to use it

  • Routine observation rounds on a paediatric ward
  • Deciding whether a child needs senior or critical-care review
  • Handover, where a trend in score carries more information than isolated vitals
  • Documenting an objective trigger for escalation

3 Formula & method

Behavioural, cardiovascular and respiratory components are each scored and summed. The app bands the total as low concern, caution, urgent review or emergency, and states the escalation implied by the band. A rising trend matters as much as any single total, so the score is designed to be repeated rather than taken once.

4 Frequently asked questions

What PEWS total should trigger escalation?

The app bands the total and names the response for each band. Local policy sets the exact trigger, so the banding should be read alongside your unit's escalation protocol.

Is a single high score enough to act on?

A high total warrants review, but so does a rising trend across observations. PEWS is intended to be tracked over time rather than used as a one-off number.

Does PEWS replace clinical judgement?

No. It is a safety net for structured observation. A clinician concerned about a child should escalate regardless of the score.

Are there different versions of PEWS?

Yes — several variants exist and units adopt local versions. The app states the components it scores so you can check it against your own chart.
