Abstract

BACKGROUND: The Pediatric Assessment Triangle (PAT) is a rapid visual assessment framework designed to support early identification of critically ill or injured children in emergency departments. It enables clinicians to quickly evaluate appearance, work of breathing, and circulation to the skin, forming the foundation for immediate triage and management decisions. This narrative review synthesizes evidence regarding the clinical applications, diagnostic accuracy, workflow integration, and emerging innovations related to PAT use in pediatric emergency medicine. METHODS: A comprehensive literature search was conducted using PubMed, Scopus, and Google Scholar databases, focusing on studies evaluating the validity, reliability, and implementation of PAT from inception through 2025. Articles addressing diagnostic accuracy, educational impact, and applicability in low-resource settings were included. RESULTS: Across available validation studies, PAT demonstrated strong diagnostic accuracy, with reported area under the receiver operating characteristic curve (AUROC) values ranging from 0.85 to 0.96 for identifying high-acuity conditions such as respiratory distress, shock, and altered mental status. Implementation has been associated with improved early recognition and team communication, although evidence of direct effects on clinical outcomes remains limited. Noted challenges include interobserver variability, inconsistent training, and limited applicability in neonates and patients with complex chronic conditions. CONCLUSION: PAT remains a practical, structured, and accessible bedside tool for rapid pediatric assessment in emergency care. Further multicenter validation, standardized education, and integration with artificial intelligence, wearable technologies, and telemedicine could enhance its accuracy, consistency, and global utility.
