Worked calculation
The values below come from this tool's own example placeholders and are computed server-side with the formula shown on this page, so the arithmetic can be checked quickly. It demonstrates how to substitute values only — it is not clinical advice and not a real case.
| Behaviour | Sleeping (1) |
|---|---|
| Cardiovascular | Pale or CRT 3 s (1) |
| Respiratory | > normal +10 or accessory muscles or FiO₂ ≥ 30%/3 L (1) |
| Continuous nebulizer (q20min bronchodilator) or CPAP | No (0) |
| Persistent post-operative vomiting | No (0) |
→PEWS3
- Components：Behaviour 1 + cardiovascular 1 + respiratory 1 = 3 (core 0–9, with add-ons 0–13)
- Action：Escalate monitoring: inform the responsible clinician, increase observation frequency (e.g. hourly), reassess the trend
- Escalation：Total ≥ 3 → escalate monitoring; ≥ 5 → consider RRT; any single domain = 3 → high risk. Compare HR/RR with age-specific ranges
| Behaviour | Playing / appropriate (0) |
|---|---|
| Cardiovascular | Pink or CRT 1–2 s (0) |
| Respiratory | Normal (0) |
| Continuous nebulizer (q20min bronchodilator) or CPAP | No (0) |
| Persistent post-operative vomiting | No (0) |
→PEWS0
- Components：Behaviour 0 + cardiovascular 0 + respiratory 0 = 0 (core 0–9, with add-ons 0–13)
- Action：Routine monitoring with periodic reassessment; carer/nurse concern can escalate regardless of score
- Escalation：Total ≥ 3 → escalate monitoring; ≥ 5 → consider RRT; any single domain = 3 → high risk. Compare HR/RR with age-specific ranges
Common questions
What is Pediatric Early Warning Score (PEWS)?
Calculate the Brighton Pediatric Early Warning Score (PEWS) to detect clinical deterioration in hospitalized children.
How is Pediatric Early Warning Score (PEWS) calculated? What is the core formula?
Behaviour + cardiovascular + respiratory (each 0–3) + continuous nebs/CPAP and post-op vomiting (+2 each). Total ≥ 3 escalate, ≥ 5 consider RRT, any single domain = 3 high risk.
When is Pediatric Early Warning Score (PEWS) used?
Early identification of deteriorating children to trigger escalation and rapid response.
What are the key clinical points for Pediatric Early Warning Score (PEWS)?
Any single domain scoring 3 is high risk regardless of total. Carer/nurse concern should be able to escalate beyond the score. Compare HR/RR against age-specific ranges.
What are the limits and cautions when using Pediatric Early Warning Score (PEWS)?
For licensed clinicians and clinical researchers. Interpret results with history, investigations and local protocols; not a diagnosis or prescription, and not a substitute for multidisciplinary decision-making or local guidelines.
Does Pediatric Early Warning Score (PEWS) upload patient data? Where is it calculated?
Calculation runs locally in the browser; inputs and results are not uploaded. For licensed clinicians only; interpret with history, investigations and local protocols — not a diagnosis or prescription.
How is Pediatric Early Warning Score (PEWS) calculated in practice? Can you show a worked example?
