What domains does PEWS assess and what threshold triggers escalation?

PEWS (Brighton/Monaghan version) assesses three domains scored 0–3 each: Behavior (playing/appropriate → sleeping → irritable → lethargic/confused); Cardiovascular (pink/capillary refill 1–2s → pale/capillary refill 3s → gray/capillary refill 4s + tachycardia → gray/capillary refill ≥5s + tachycardia + bradycardia); Respiratory (within normal parameters → >10 above normal + accessory muscles → >20 above normal + retractions → 5 below normal or stereotyped/grunting). A PEWS score ≥3 requires escalation; ≥7 requires emergency response.

Are there age-specific PEWS modifications?

Yes. Because normal physiological parameters differ by age in children (heart rate, respiratory rate, and blood pressure norms vary from neonate to adolescent), most PEWS implementations include age-adjusted tables or reference ranges. Several validated versions exist (Brighton, Canadian PEWS, PICU-specific). Implementing PEWS should include staff education on age-specific normal values to ensure accurate scoring and appropriate escalation.
