Critical injuries in paediatric pedestrians
Insights
Child pedestrian injuries in New Zealand disproportionately affect Māori and Pacific children. Most severe injuries target the head, often resulting in death, highlighting a critical child health issue.
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.
Abstract:
Data are presented on all sixty-four children who were injured as pedestrians and admitted to the department of critical care medicine, Auckland Hospital over a four year period. Median age was six years, with a male:female ratio of 1.6:1.0. Admission rates were 3.1 and 3.0 times higher for Maori and Pacific Island children, respectively, than for children of European origin. Fifty-two percent of injuries occurred between 3 pm and 7 pm. Median injury severity score (ISS) was 29, and 95% of patients had an ISS of 16 or more. Life threatening injuries were most commonly to the head, whilst less severe injuries, commonly fractures, were to the limbs. The combination of head and lower limb injury was seen in 53% of patients. Twenty-nine patients had 34 operative procedures: 16 orthopaedic, six neurosurgical, four laparotomies and eight wound debridement and closure. Eighty-one percent of the patients received ventilatory support and nine patients (14%) died, all from brain injuries. Pedestrian injury is an important child health problem in New Zealand and studies aimed at the identification of factors that place children at risk for these injuries are needed.
