Overview

• The Pediatric Emergency Research Network (PERN) developed predictive models to classify pediatric pneumonia as mild, moderate, or severe with high accuracy.
• These tools were validated using data from over 2,200 children across 73 emergency departments in 14 countries, enhancing global applicability.
• Key indicators for severe cases include abdominal pain, refusal to drink, chest retractions, hypoxemia, and multilobar lung involvement on chest radiographs.
• The models aim to complement clinician judgment, reducing unnecessary hospitalizations and ensuring timely care for at-risk children.
• Published in *The Lancet Child & Adolescent Health*, the models now await external validation before potential integration into clinical guidelines.
