Common denominators in death from pediatric back-over trauma

Area of Science:

• Pediatric Trauma
• Injury Prevention
• Automotive Safety

Background:

• Low-speed "back-over" injuries represent a small fraction of pediatric automobile versus pedestrian (AVP) trauma.
• These specific injuries are disproportionately severe, leading to a higher mortality rate among children.

Purpose of the Study:

• To identify common environmental, mechanistic, and demographic factors associated with fatal pediatric back-over injuries.
• To inform targeted injury prevention strategies for this vulnerable population.

Main Methods:

• Retrospective review of pediatric AVP injuries (ages 4 and younger) from an urban Level I trauma center's registry (1995-2010).
• Analysis focused on identifying mortalities specifically from back-over incidents.
• Demographic, injury severity, and environmental data were collected and compared between back-over and non-back-over fatalities.

Main Results:

• Out of 535 pediatric AVP injuries, 31 (5.79%) were fatal, with 6 (19.3% of mortalities) resulting from back-over incidents.
• Victims of fatal back-over injuries were significantly younger (mean age 1.33 years) than other AVP fatalities (mean age 3.5 years).
• Fatalities predominantly involved massive blunt head trauma, occurred in the patient's driveway, and involved a vehicle driven by a family member or acquaintance.

Conclusions:

• Fatal pediatric back-over injuries are characterized by very young age, severe head trauma, and occur in driveways with familiar drivers.
• These findings highlight critical factors for developing effective prevention measures to reduce child fatalities from back-over incidents.
