Pediatric early warning score versus a paediatric triage tool in the emergency department: A reliability study.

Rapid Emergency Triage and Treatment System-pediatric assigned a higher urgency than PEWS. The inter-tool agreement between PEWS and RETTS-p was low (weighted kappa [95% confidence interval [CI] = 0.32 [0.24-0.40]]). Weighted kappa (95% CI) was 0.50 (0.41-0.59) for PEWS and RETTS-p without ESS, indicating that PEWS is not equivalent to five-level triage tools.
