Effects of Seating Position and Appropriate Restraint Use on the Risk of Injury to Children in Motor Vehicle Crashes

Background. Currently, many states are upgrading their child restraint laws to include provisions for the use of age-appropriate restraints through 6 to 8 years of age, with some also requiring rear seating for children, enabling the laws to be in closer alignment with best-practice recommendations. Objective. To evaluate the relationships of seating position and restraint status to the risk of injury among children in passenger vehicle crashes. Methods. This was a cross-sectional study of children <16 years of age who were involved in crashes of insured vehicles in 15 states, with data collected via insurance claims records and a telephone survey. A probability sample of 17980 children in 11506 crashes, representing 229106 children in 146613 crashes, was collected between December 1, 1998, and November 30, 2002. Parent reports were used to define restraint status, seating position, and occurrence of clinically significant injuries, with the use of a previously validated instrument. Results. Approximately 62% of the children used seat belts, 35% used child restraints, and 3% used no restraint. Nearly 4 of 5 children sat in the rear seat, with one half of all children being restrained appropriately for their age in the rear, although this varied according to the age of the child. Overall, 1.6% of children suffered serious injuries, 13.5% had minor injuries, and 84.9% did not have any injury. Unrestrained children in the front were at the highest risk of injury and appropriately restrained children in the rear were at the lowest risk, for all age groups. Inappropriately restrained children were at nearly twice the risk of injury, compared with appropriately restrained children (odds ratio [OR]: 1.8; 95% confidence interval [CI]: 1.4–2.3), whereas unrestrained children were at >3 times the risk (OR: 3.2; 95% CI: 2.5–4.1). The effect of seating row was smaller than the effect of restraint status; children in the front seat were at 40% greater risk of injury, compared with children in the rear seat (OR: 1.4; 95% CI: 1.2–1.7). Had all children in the study population been appropriately restrained in the rear seat, 1014 serious injuries (95% CI: 675–1353 injuries) would have been prevented (with the assumption that restraint effectiveness does not depend on a variety of other driver-related, child-related, crash-related, vehicle-related, and environmental factors). Conclusions. Age-appropriate restraint confers relatively more safety benefit than rear seating, but the 2 work synergistically to provide the best protection for children in crashes. These results support the current focus on age-appropriate restraint in recently upgraded state child restraint laws. However, it is important to note that considerable added benefit would be realized with additional requirements for rear seating.

Assessing pediatric senior residents' training in resuscitation: Fund of knowledge, technical skills, and perception of confidence

Objective To describe pediatric housestaff knowledge, experience, confidence in pediatric resuscitations and their ability to perform important resuscitation procedures during the usual training experience. Design and participants Cohort study of PGY-3 level residents in a ACGME accredited pediatric residency training program at a large, tertiary care children’s hospital. Methods Fund of knowledge was assessed by administering the standardized test from the Pediatric Advanced Life Support (PALS) Course in addition to a supplemental short answer test requiring clinical problem-solving skills. Procedural skills were evaluated through observation of the resident performing four procedures during a skills workshop using a weighted step-wise grading sheet. Resident experience and confidence was quantified using an anonymous survey. Results Ninety-seven percent of residents participated. Residents achieved high scores on the standardized PALS test (93.2% ± 5.5), but performed less well when answering more complicated questions (60.0% ± 9.9) on the short answer test. No resident was able to successfully perform both basic and advanced airway skills, and only 11% successfully completed both vascular skills. Although residents were overall confident in their resuscitation skills, performance in the skill workshop revealed significant deficits. For example, only 18% performed ancillary airway maneuvers properly. None of the residents performed all four skills correctly. Experience in both real and mock resuscitations was infrequent. Residents reported receiving feedback on their performance less than half of the time. Over 89% of them felt that resuscitation knowledge and skill were important for their future chosen career. Conclusion Pediatric residents infrequently lead or participate in real or mock resuscitations. Although confident in performing many of the necessary resuscitation skills, few residents performed critical components of these skills correctly. Current pediatric residency training may not provide sufficient experience to develop adequate skills, fund of knowledge, or confidence needed for resuscitation.

Child passenger safety.

Despite significant reductions in the number of children killed in motor vehicle crashes over the past decade, crashes continue to be the leading cause of death for children 4 years and older. Therefore, the American Academy of Pediatrics continues to recommend inclusion of child passenger safety anticipatory guidance at every health-supervision visit. This technical report provides a summary of the evidence in support of 5 recommendations for best practices to optimize safety in passenger vehicles for children from birth through adolescence that all pediatricians should know and promote in their routine practice. These recommendations are presented in the revised policy statement on child passenger safety in the form of an algorithm that is intended to facilitate their implementation by pediatricians with their patients and families. The algorithm is designed to cover the majority of situations that pediatricians will encounter in practice. In addition, a summary of evidence on a number of additional issues that affect the safety of children in motor vehicles, including the proper use and installation of child restraints, exposure to air bags, travel in pickup trucks, children left in or around vehicles, and the importance of restraint laws, is provided. Finally, this technical report provides pediatricians with a number of resources for additional information to use when providing anticipatory guidance to families.

Effect of high-fidelity simulation on Pediatric Advanced Life Support training in pediatric house staff: a randomized trial.

Objectives: To assess the effect of high-fidelity simulation (SIM) on cognitive performance after a training session involving several mock resuscitations designed to teach and reinforce Pediatric Advanced Life Support (PALS) algorithms. Methods: Pediatric residents were randomized to high-fidelity simulation (SIM) or standard mannequin (MAN) groups. Each subject completed 3 study phases: (1) mock code exercises (asystole, tachydysrhythmia, respiratory arrest, and shock) to assess baseline performance (PRE phase), (2) a didactic session reviewing PALS algorithms, and (3) repeated mock code exercises requiring identical cognitive skills in a different clinical context to assess change in performance (POST phase). SIM subjects completed all 3 phases using a high-fidelity simulator (SimBaby, Laerdal Medical, Stavanger, Norway), and MAN subjects used SimBaby without simulated physical findings (ie, as a standard mannequin). Performance in PRE and POST was measured by a scoring instrument designed to measure cognitive performance; scores were scaled to a range of 0 to 100 points. Improvement in performance from PRE to POST phases was evaluated by mixed modeling using a random intercept to account for within-subject variability. Results: Fifty-one subjects (SIM, 25; MAN, 26) completed all phases. The PRE performance was similar between groups. Both groups demonstrated improvement in POST performance. The improvement in scores between PRE and POST phases was significantly better in the SIM group (mean [SD], 11.1 [4.8] vs. 4.8 [1.7], P = 0.007). Conclusions: The use of high-fidelity simulation in a PALS training session resulted in improved cognitive performance by pediatric house staff. Future studies should address skill and knowledge decays and team dynamics, and clearly defined and reproducible outcome measures should be sought.

Policy Statement—Child Passenger Safety

Child passenger safety has dramatically evolved over the past decade; however, motor vehicle crashes continue to be the leading cause of death of children 4 years and older. This policy statement provides 4 evidence-based recommendations for best practices in the choice of a child restraint system to optimize safety in passenger vehicles for children from birth through adolescence: (1) rear-facing car safety seats for most infants up to 2 years of age; (2) forward-facing car safety seats for most children through 4 years of age; (3) belt-positioning booster seats for most children through 8 years of age; and (4) lap-and-shoulder seat belts for all who have outgrown booster seats. In addition, a fifth evidence-based recommendation is for all children younger than 13 years to ride in the rear seats of vehicles. It is important to note that every transition is associated with some decrease in protection; therefore, parents should be encouraged to delay these transitions for as long as possible. These recommendations are presented in the form of an algorithm that is intended to facilitate implementation of the recommendations by pediatricians to their patients and families and should cover most situations that pediatricians will encounter in practice. The American Academy of Pediatrics urges all pediatricians to know and promote these recommendations as part of child passenger safety anticipatory guidance at every health-supervision visit.

Effectiveness of Belt Positioning Booster Seats: An Updated Assessment

OBJECTIVE: The objective of this study was to provide an updated estimate of the effectiveness of belt-positioning booster (BPB) seats compared with seat belts alone in reducing the risk for injury for children aged 4 to 8 years. METHODS: Data were collected from a longitudinal study of children who were involved in crashes in 16 states and the District of Columbia from December 1, 1998, to November 30, 2007, with data collected via insurance claims records and a validated telephone survey. The study sample included children who were aged 4 to 8 years, seated in the rear rows of the vehicle, and restrained by either a seat belt or a BPB seat. Multivariable logistic regression was used to determine the odds of injury for those in BPB seats versus those in seat belts. Effects of crash direction and booster seat type were also explored. RESULTS: Complete interview data were obtained on 7151 children in 6591 crashes representing an estimated 120646 children in 116503 crashes in the study population. The adjusted relative risk for injury to children in BPB seats compared with those in seat belts was 0.55. CONCLUSIONS: This study reconfirms previous reports that BPB seats reduce the risk for injury in children aged 4 through 8 years. On the basis of these analyses, parents, pediatricians, and health educators should continue to recommend as best practice the use of BPB seats once a child outgrows a harness-based child restraint until he or she is at least 8 years of age.

Health care utilization and needs after pediatric traumatic brain injury.

OBJECTIVE. Children with moderate to severe traumatic brain injury (TBI) show early neurobehavioral deficits that can persist several years after injury. Despite the negative impact that TBI can have on a childs physical, cognitive, and psychosocial well-being, only 1 study to date has documented the receipt of health care services after acute care and the needs of children after TBI. The purpose of this study was to document the health care use and needs of children after a TBI and to identify factors that are associated with unmet or unrecognized health care needs during the first year after injury. METHODS. The health care use and needs of children who sustained a TBI were obtained via telephone interview with a primary caregiver at 2 and 12 months after injury. Of the 330 who enrolled in the study, 302 (92%) completed the 3-month and 288 (87%) completed the 12-month follow-up interviews. The health care needs of each child were categorized as no need, met need, unmet need, or unrecognized need on the basis of the childs use of post-acute services, the caregivers report of unmet need, and the caregivers report of the childs functioning as measured by the Pediatric Quality of Life Inventory (PedsQL). Regardless of the use of services or level of function, children of caregivers who reported an unmet need for a health care service were defined as having unmet need. Children who were categorized as having no needs were defined as those who did not receive services; whose caregiver did not report unmet need for a service; and the whose physical, socioemotional, and cognitive functioning was reported to be normal by the caregiver. Children with met needs were those who used services in a particular domain and whose caregivers did not report need for additional services. Finally, children with unrecognized needs were those whose caregiver reported cognitive, physical, or socioemotional dysfunction; who were not receiving services to address the dysfunction; and whose caregiver did not report unmet need for services. Polytomous logistic regression was used to model unmet and unrecognized need at 3 and 12 months after injury as a function of child, family, and injury characteristics. RESULTS. At 3 months after injury, 62% of the study sample reported receiving at least 1 outpatient health care service. Most frequently, children visited a doctor (56%) or a physical therapist (27%); however, 37% of caregivers reported that their child did not see a physician at all during the first year after injury. At 3 and 12 months after injury, 26% and 31% of children, respectively, had unmet/unrecognized health care needs. The most frequent type of unmet or unrecognized need was for cognitive services. The top 3 reasons for unmet need at 3 and 12 months were (1) not recommended by doctor (34% and 31%); (2) not recommended/provided by school (16% and 17%); and (3) cost too much (16% and 16%). Factors that were associated with unmet or unrecognized need changed over time. At 3 months after injury, the caregivers of children with a preexisting psychosocial condition were 3 times more likely to report unmet need compared with children who did not have one. Also, female caregivers were significantly more likely to report unmet need compared with male caregivers. Finally, the caregivers of children with Medicaid were almost 2 times more likely to report unmet need compared with children who were covered by commercial insurance. The only factor that was associated with unrecognized need at 3 months after injury was abnormal family functioning. At 12 months after injury, although TBI severity was not significant, children who sustained a major associated injury were 2 times more likely to report unmet need compared with children who did not. Consistent with the 3-month results, the caregivers of children with Medicaid were significantly more likely to report unmet needs at 1 year after injury. In addition to poor family functionings being associated with unrecognized need, nonwhite children were significantly more likely to have unrecognized needs at 1 year compared with white children. CONCLUSIONS. A substantial proportion of children with TBI had unmet or unrecognized health care needs during the first year after injury. It is recommended that pediatricians be involved in the post-acute care follow-up of children with TBI to ensure that the injured childs needs are being addressed in a timely and appropriate manner. One of the recommendations that trauma center providers should make on hospital discharge is that the parent/primary caregiver schedule a visit with the childs pediatrician regardless of the post-acute services that the child may be receiving. Because unmet and unrecognized need was highest for cognitive services, it is important to screen for cognitive dysfunction in the primary care setting. Finally, because the health care needs of children with TBI change over time, it is important for pediatricians to monitor their recovery to ensure that children with TBI receive the services that they need to restore their health after injury.

An evaluation of the effectiveness of forward facing child restraint systems

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.

Prevalence of teen driver errors leading to serious motor vehicle crashes

OBJECTIVES Motor vehicle crashes are the leading cause of adolescent deaths. Programs and policies should target the most common and modifiable reasons for crashes. We estimated the frequency of critical reasons for crashes involving teen drivers, and examined in more depth specific teen driver errors. METHODS The National Highway Traffic Safety Administrations (NHTSA) National Motor Vehicle Crash Causation Survey collected data at the scene of a nationally representative sample of 5470 serious crashes between 7/05 and 12/07. NHTSA researchers assigned a single driver, vehicle, or environmental factor as the critical reason for the event immediately leading to each crash. We analyzed crashes involving 15-18 year old drivers. RESULTS 822 teen drivers were involved in 795 serious crashes, representing 335,667 teens in 325,291 crashes. Driver error was by far the most common reason for crashes (95.6%), as opposed to vehicle or environmental factors. Among crashes with a driver error, a teen made the error 79.3% of the time (75.8% of all teen-involved crashes). Recognition errors (e.g., inadequate surveillance, distraction) accounted for 46.3% of all teen errors, followed by decision errors (e.g., following too closely, too fast for conditions) (40.1%) and performance errors (e.g., loss of control) (8.0%). Inadequate surveillance, driving too fast for conditions, and distracted driving together accounted for almost half of all crashes. Aggressive driving behavior, drowsy driving, and physical impairments were less commonly cited as critical reasons. Males and females had similar proportions of broadly classified errors, although females were specifically more likely to make inadequate surveillance errors. CONCLUSIONS Our findings support prioritization of interventions targeting driver distraction and surveillance and hazard awareness training.

Family Burden After Traumatic Brain Injury in Children

OBJECTIVE. Traumatic brain injury has a substantial impact on caregivers. This study describes the burden experienced by caregivers of children with traumatic brain injury and examines the relationship between child functioning and family burden during the first year after injury. PATIENTS AND METHODS. Children aged 5 to 15 years hospitalized for traumatic brain injury at 4 participating trauma centers were eligible. Caregivers completed baseline and 3- and 12-month telephone interviews measuring the childs health-related quality of life using the Pediatric Quality of Life Inventory. The emotional impact scale of the Child Health Questionnaire was used to identify caregivers with substantial distress, including general worry or interference with family routine. Caregiver perceptions of whether health care needs were met or unmet and days missed from work were also measured. RESULTS. A total of 330 subjects enrolled; follow-up was conducted with 312 at 3 months and 288 at 12 months. Most subjects were white (68%) and male (69%). Abnormal Pediatric Quality of Life Inventory subscores were related to substantial caregiver burden (either general worry or interference in routine). These abnormalities were reported by >75% of patients at 3 months and persisted to 1 year in some patients. Parental perception of unmet health care needs was strongly related to family burden outcomes, with up to 69% of this subset of parents reporting substantial worry, and nearly one quarter reporting interference with daily routine/concentration 1 year after injury. Child dysfunction predicted parental burden at 3 and 12 months. Burden was greater when health care need was unmet. Abnormalities on the Pediatric Quality of Life Inventory predicted the amount of work missed by parents, especially in the presence of unmet needs. CONCLUSIONS. Caregivers are more likely to report family burden problems when child functioning is poorer and health care needs are unmet. Improved identification and provision of services is a potentially modifiable factor that may decrease family burden after pediatric traumatic brain injury.
