Insights
Child occupants can be seriously injured in motor vehicle noncrash events like sudden stops. Unrestrained children face a significant risk of ejection or impact injuries, highlighting a need for broader safety messaging.
Area of Science:
- Pediatric injury prevention
- Traffic safety research
- Emergency medicine
Background:
- Child occupant injuries in motor vehicles are typically studied in crash events.
- Injuries from noncrash events are often unrecorded and underreported.
- Existing health education focuses primarily on crash-related risks.
Purpose of the Study:
- To determine the incidence of medically confirmed injuries to child occupants from noncrash motor vehicle events.
- To characterize the nature and severity of these injuries.
- To inform public health messaging on child passenger safety.
Main Methods:
- Retrospective review of emergency room visits for child occupants over 18 months.
- Identification of injuries resulting from noncrash events (sudden stops, swerves, occupant movement).
- Documentation of injury mechanisms, restraint use, and injury severity (Abbreviated Injury Scale).
Main Results:
- 18% (23%) of 79 child occupants studied sustained injuries in noncrash events.
- Mechanisms included ejection or impact with vehicle interior.
- None of the injured children with known restraint status were restrained.
- Injuries ranged from minor (AIS 1) to severe (AIS 3).
Conclusions:
- Noncrash events pose a significant, underrecognized risk of injury to child occupants.
- Lack of restraint use is a key factor in these injuries.
- Future health education should include the risks associated with noncrash events alongside crash risks.
Abstract:
Data on injuries sustained by child occupants in motor vehicles occurring in noncrash events are generally unrecorded. This study was undertaken to ascertain the occurrence of medically confirmed injuries sustained by child occupants in motor vehicles as a result of noncrash events. Seventy-nine children were seen in the emergency room for evaluation of injuries that they incurred as occupants in motor vehicle incidents over a period of 18 months. The majority of injuries occurred in crash events. However, 18 (23%) were injured in noncrash events. These events included sudden stops, swerves, turns, and movement of an unrestrained child within the vehicle. The mechanism of injury was either ejection from the vehicle or impact with an interior area of the vehicle. In five of the 18 cases safety restraint use could not be established. Of the 13 cases in which information was obtained, no child was restrained. Although the injuries were predominantly minor (Abbreviated Injury Scale (AIS) 1), two children sustained moderate injury (AIS 2), and one child sustained severe injury (AIS 3). These results need to be confirmed by a larger study and if confirmed, the additional hazard of injury from noncrash events should be incorporated into health education messages that currently place primary emphasis on the potential for injury in crash events.
