Summary

This study addresses the persistent problem of inadequate child passenger restraint use, which contributes to preventable deaths and injuries from motor vehicle collisions (MVCs). Despite legal mandates, many children are prematurely placed in seat belts or ride unrestrained. The research investigates two specific areas: the impact of carpooling on booster seat usage among parents and the role emergency physicians play in promoting child passenger safety during ED visits. The study aims to identify practical barriers to restraint use and explore the emergency department as a novel setting for injury prevention education. The researchers conducted a two-part national survey study. Part 1 involved a cross-sectional web-based survey of 693 parents of children aged 4 to 8 years, drawn from a nationally representative panel. The survey assessed parental restraint practices, awareness of state laws, and experiences with booster seats during carpooling. Part 2 surveyed 1,200 emergency physicians (including pediatric and general emergency medicine specialists) via mail. This survey evaluated physicians’ attitudes, knowledge, and self-reported behaviors regarding child passenger safety promotion during MVC-related ED visits, using clinical scenarios to gauge specific interventions. Statistical analyses included chi-square tests and multivariate logistic regression to compare groups and control for demographic variables. In the parent survey, 76% of respondents reported using a child passenger restraint system (car seat or booster), while 24% used only a seat belt. Restraint use declined significantly with age, dropping from 92% for ages 4–6 to 52% for ages 7–8. Carpooling was common, with 65% of parents reporting they transport other children. Booster seat use was lower during carpooling trips compared to usual family travel. Parents who never carpooled were more likely to perceive booster seats as inconvenient for seating arrangements. In the physician survey, 638 eligible respondents participated. Pediatric emergency medicine (PEM) physicians demonstrated greater awareness of safety resources and were significantly more likely than general emergency medicine (GEM) physicians to promote safety behaviors. For example, in a scenario involving a 6-year-old in the front seat, PEM physicians were more likely to inform parents the child was too young for the front seat and recommend a booster. In a scenario involving a 3-year-old in a rollover crash, PEM physicians were far more likely to recommend replacing the car seat even without visible damage. However, overall, many physicians reported low likelihood of providing written safety information or referrals at discharge. The findings indicate that carpooling presents a practical barrier to consistent booster seat use, suggesting that public health efforts must address social norms and logistical challenges associated with shared transportation. Regarding clinical practice, while emergency physicians acknowledge their role in injury prevention, there is substantial room for improvement in the frequency and consistency of safety messaging. PEM physicians are more proactive than GEM physicians, but both groups underutilize discharge opportunities for education. The study concludes that increasing clinician and parental awareness of the benefits of booster seats, particularly in carpooling contexts, and enhancing ED-based promotion of child passenger safety could help reduce preventable injuries.

Key finding

Carpooling is associated with reduced booster seat usage among parents, and pediatric emergency medicine physicians are significantly more likely than general emergency medicine physicians to provide child passenger safety education and recommendations during emergency department visits.
