Critical injuries in paediatric pedestrians

Area of Science:

• Pediatric Critical Care
• Trauma Surgery
• Public Health

Background:

• Childhood pedestrian injuries represent a significant public health concern.
• Previous research indicates disparities in injury rates among different ethnic groups.

Purpose of the Study:

• To analyze the characteristics and outcomes of children admitted to critical care following pedestrian injuries.
• To identify demographic and injury patterns in pediatric pedestrian trauma.

Main Methods:

• Retrospective review of 64 pediatric pedestrian injury cases admitted to Auckland Hospital's critical care department over four years.
• Data collected included patient demographics, injury severity (Injury Severity Score - ISS), injury types, surgical interventions, and mortality.

Main Results:

• The study included 64 children (median age 6 years; male:female ratio 1.6:1.0).
• Māori and Pacific children had significantly higher admission rates compared to European children (3.1x and 3.0x, respectively).
• Most injuries occurred between 3 pm and 7 pm, with a median ISS of 29. Head injuries were most severe, while limb fractures were common. 53% had combined head and lower limb injuries. 14% of patients died, all from brain injuries. 81% required ventilatory support.

Conclusions:

• Pedestrian injuries pose a serious threat to child health in New Zealand, with notable ethnic disparities.
• Urgent need for further research to identify risk factors and develop targeted prevention strategies for child pedestrian trauma.
