ABSTRACT The objective of this study was to determine the effectiveness of forward facing child restraint systems (FFCRS) in preventing serious injury and hospitalization to children 12-47 months of age as compared with similar age children in seat belts. Data were obtained from a cross-sectional study of children aged 12-47 months in crashes of insured vehicles in 15 states, with data collected via insurance claims records and a telephone survey. Effectiveness estimates were limited to those children between 12 and 47 months of age seated in the back row(s) of vehicles, restrained in FFCRS, regardless of misuse, or seat belts of all types and usage. Completed survey information was obtained on 1207 children, representing 12632 children in 11619 crashes between 1 December 1998 and 31 May 2002. Serious injuries occurred to 0.47% of all 12-47-month olds studied, including 1.72% of those in seat belts and 0.39% of those in child restraint systems. The risk of serious injury was 78% lower for children in FFCRS than in seat belts (odds ratio (OR) = 0.22, 95% confidence interval (CI) = 0.11-0.45, P = 0.001). The risk of hospitalization was 79% lower for children in FFCRS than in seat belts (OR = 0.21, 95% CI = 0.09-050, P = 0.001). There was no difference between the restraint types in preventing minor injuries. As compared with seat belts, CRS are very highly effective in preventing serious injuries and hospitalization, respectively. This effectiveness estimate is substantially higher than older estimates, demonstrating the benefits of current CRS designs. These results provide those educating parents and caregivers population-based data on the importance of child restraint use.

    • "Unfortunately , non-medical professionals provide the injury assessment in many studies [10] [12] [13]. As a result, some types of head injuries are excluded from evaluation [12]. Head injuries are the most common type of injury sustained by children in MVCs and have been identified as a target of injury prevention [4] [14] [15]. "

    ABSTRACT: We observed a high incidence of traumatic brain injuries (TBI) in properly restrained infants involved in higher speed motor vehicle crashes (MVCs). We hypothesized that car safety seats are inadequately protecting infants from TBI. We retrospectively queried scene crash data from our State Department of Transportation (2007-2011) and State Department of Public Health data (2000-2011) regarding infants who presented to a trauma center after MVC. Department of Transportation data revealed 94% of infants in MVCs were properly restrained (782/833) with average speed of 44.6 miles/h when there was concern for injury. Department of Public Health data showed only 67/119 (56.3%) of infants who presented to a trauma center after MVC were properly restrained. Properly restrained infants were 12.7 times less likely to present to a trauma center after an MVC (OR=12.7, CI 95% 5.6-28.8, p<0.001). TBI was diagnosed in 73/119 (61.3%) infants; 42/73 (57.5%) properly restrained, and 31/73 (42.5%) improperly/unrestrained (p=0.34). Average head abbreviated injury scale was similar for properly restrained (3.2±0.2) and improperly/unrestrained infants (3.5±0.2, p=0.37). Car safety seats prevent injuries. However, TBI is similar among properly restrained and improperly/unrestrained infants involved in higher speed MVCs who present to a trauma center.

    • "Unintentional injuries due to motor vehicle crashes (MVCs) are the leading cause of death and long-term disability between the ages of 4–14 years [1] [2]. When properly installed, child safety seats have been shown to reduce the risk of childhood injury by 71% to 82% and death by 28% relative to seat belts alone [3] [4] [5] [6]. Within the subset of four-to eightyear olds, booster seats reduced the risk of nonfatal injury by 45% relative to seat belts alone [7]. "

    ABSTRACT: . Motor vehicle crashes are the leading cause of death among US children aged 4-14 years. In theory, health provider counseling about Child Passenger Safety (CPS) could be a useful deterrent. The data about the effectiveness of CPS dissemination is sparse, but existing results suggest that providers are not well informed. Moreover, there is insufficient evidence to determine whether provider counseling about CPS is effective. . We therefore assessed CPS best practice knowledge among 217 healthcare workers at hospitals in seven cities throughout the USA and evaluated the impact of a brief, lunch and learn educational intervention with a five-item questionnaire. Attendees were comprised of physicians, nurses, social workers, pediatric residents, and pediatric trauma response teams. . Pre-post survey completion was nearly 100% (216 of 217 attendees). Participation was fairly evenly distributed according to age (18-29, 30-44, and 45+ years). More than 80% of attendees were women. Before intervention, only 4% of respondents (9/216) answered all five questions correctly; this rose to 77% (167/216) ( < 0.001, using a Wilcoxon signed-rank test) after intervention. . Future research should consider implementation and controlled testing of comparable educational programs to determine if they improve dissemination of CPS best practice recommendations in the long term.

    • "For several years child passenger safety researchers focused most of their attention on children under age 8. Evidence of the safety benefits of child restraints for these younger children is robust (Arbogast et al., 2004a; Durbin et al., 2003, 2005; Elliott et al., 2006a; Henary et al., 2007). As a result, the use of age-appropriate restraints by younger children has increased markedly over the past 9 years (The Children's Hospital of Philadelphia, 2007; Durbin et al., 2001a; Winston et al., 2003, 2004, 2007).

    ABSTRACT: The American Academy of Pediatrics and the National Highway Traffic Safety Administration currently recommend that, unless they are under 57in. in height, 8-12-year-old children use seat belts and all should ride in the rear seats of vehicles. These recommendations assume that the vehicle seat belt should provide adequate protection for these older children in the event of a crash. To describe characteristics of older children in the rear seat using seat belts in crashes, to estimate their risk and body region distribution of injury, and to identify risk factors for injury. A representative sample of 6680 seat belt-restrained occupants, 8-12 years of age, seated in the rear seat during crashes involving insured vehicles in 16 US states between December 1998 and December 2007. A telephone interview was conducted with the driver of each vehicle. The main outcome was the parent-reported injury defined as Abbreviated Injury Scale (AIS) 2 or greater injuries. The risk of injury for belted 8-12 year olds in the rear seat was 1.3%. Head injury was the most common injury (60%), followed by injuries to the face (9%), upper extremity (9%) and abdomen (9%). One out of five (21%) 8-12 year olds either did not use the shoulder portion of the vehicle seat belt or placed it incorrectly behind their back or under their arm. Bivariate analyses indicated a higher risk of injury for these children (1.8%) as compared to children using both the lap and shoulder portions of the seat belt (1.1%). However, this difference was not statistically significant when other risk factors such as crash severity and characteristics of the driver were considered. Injuries to the head, face, abdomen and upper extremity are the most common injuries to target for improved protection among 8-12 year olds in seat belts. Driver and crash characteristics are important risk factors for injury. A recent federal motor vehicle safety standard requiring lap and shoulder belts in all rear seat positions has the potential to further decrease the risk of injury to older children using seat belts.
