🧒 Pediatric Early Warning Score (PEWS)
Calculate the Brighton Pediatric Early Warning Score (PEWS) to detect clinical deterioration in hospitalized children.
Clinical takeaway
Any single domain scoring 3 is high risk regardless of total.

When to use
Early identification of deteriorating children to trigger escalation and rapid response.
How it works
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.
Key points
- 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.

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 | 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
| Behaviour | Lethargic/confused or reduced response to pain (3) |
|---|---|
| Cardiovascular | Grey/mottled or CRT ≥ 5 s or HR > normal +30 or bradycardia (3) |
| Respiratory | < normal −5 with recession/grunting or FiO₂ ≥ 50%/8 L (3) |
| Continuous nebulizer (q20min bronchodilator) or CPAP | Yes (+2) |
| Persistent post-operative vomiting | Yes (+2) |
→PEWS13
- Components：Behaviour 3 + cardiovascular 3 + respiratory 3 + add-on 4 = 13 (core 0–9, with add-ons 0–13)
- Action：High risk: immediate clinician/team review, consider activating the rapid response team (RRT), escalate monitoring; any single domain = 3 is high risk (a domain scores 3)
- Escalation：Total ≥ 3 → escalate monitoring; ≥ 5 → consider RRT; any single domain = 3 → high risk. Compare HR/RR with age-specific ranges
