Unnecessary Scans Lead to Unnecessary Re-scans: Evaluating Clinical Management of Low and Intermediate Risk Pediatric Traumatic Brain Injuries

In brief

This study examines resource utilization when clinicians order head CTs for low-risk pediatric head trauma patients outside PECARN guideline recommendations. The research highlights how non-indicated initial imaging leads to cascading healthcare costs, prolonged hospital stays, and unnecessary radiation exposure in children who would not have required CT scanning under evidence-based protocols.

• PECARN guidelines identify high-risk pediatric head trauma patients who benefit from CT; deviation exposes low-risk children to unnecessary radiation.
• Non-indicated head CTs in low/intermediate-risk patients increase hospital costs, length of stay, and parental anxiety without clinical benefit.
• Incidental findings on non-indicated CTs often trigger cascading resource utilization including repeat imaging and prolonged observation.
• Adherence to evidence-based PECARN criteria reduces overuse of CT in pediatric mild traumatic brain injury while maintaining safety.
• Clinically unimportant findings on non-indicated scans lead to unnecessary re-scans and interventions in low-risk pediatric head trauma.
