Pediatric Early Warning Scores Before Rapid Response Poorly Predict Intensive Care Unit Transfers.

Area of Science:

• Pediatric critical care medicine
• Clinical risk assessment tools
• Patient safety

Background:

• The Pediatric Early Warning Score (PEWS) is used to identify children at risk of deterioration.
• Its effectiveness, especially in high-resource settings, is debated.
• This study evaluated PEWS for predicting unplanned PICU transfers post-RRT activation.

Purpose of the Study:

• To assess the predictive performance of the Pediatric Early Warning Score (PEWS).
• To determine if PEWS can predict unplanned PICU transfers following pediatric rapid response team (RRT) activation.
• To evaluate PEWS's ability to predict rapid escalation of care.

Main Methods:

• Retrospective cohort study of pediatric patients (up to 21 years) with RRT activations.
• Collected demographic, clinical data, RRT reason, and modified Brighton PEWS.
• Analyzed PICU transfer and rapid escalation of care as outcomes; calculated sensitivity, specificity, and AUROC.

Main Results:

• 183 of 297 RRT activations (63%) led to PICU transfer, mostly respiratory.
• PEWS was recorded within 4 hours for 89% of RRT activations.
• PEWS showed low predictive value for PICU transfer or rapid escalation (AUROC 0.495-0.613).

Conclusions:

• PEWS within 4 hours before RRT activation poorly predicted PICU transfer or rapid escalation.
• Current PEWS may lack sensitivity and specificity for this purpose.
• Development of improved predictive tools is necessary.
