Validation of Pediatric Emergency Care Applied Research Network (PECARN) rule in children with minor head trauma

Area of Science:

• Pediatric Emergency Medicine
• Clinical Decision Rules
• Neurotrauma

Background:

• The Pediatric Emergency Care Applied Research Network (PECARN) rule is a widely used clinical decision tool for managing mild head trauma in children.
• Validating its effectiveness in diverse populations, such as Korean children, is crucial for global applicability.

Purpose of the Study:

• To validate the accuracy and utility of the PECARN rule for predicting the need for computed tomography (CT) scans in Korean pediatric patients with head trauma.
• To assess the rule's performance in identifying children at very low risk for clinically important traumatic brain injury (ciTBI).

Main Methods:

• A multicenter, retrospective, observational cohort study involving 448 pediatric patients with head trauma across two Korean teaching pediatric emergency departments (PEDs).
• Risk stratification using clinical decision support software based on the PECARN rule.
• Follow-up via phone calls for 7 to 90 days post-discharge to identify outcomes.

Main Results:

• The PECARN rule demonstrated 100% sensitivity across all age groups for detecting ciTBI.
• No ciTBI cases were found in the very-low-risk group, confirming its safety.
• CT scan utilization was significantly lower (14.7%) compared to the original PECARN study (33.8%).

Conclusions:

• The PECARN rule is a valid and effective tool for managing mild head trauma in Korean children, enabling safe reduction in CT scan rates.
• The rule successfully identifies low-risk pediatric patients, minimizing unnecessary radiation exposure without compromising the detection of serious brain injuries.
