RESUMEN
BACKGROUND: Surgery causes transient impairment in cognition and function, which may impact driving safety. The authors hypothesized that the risk of a motor vehicle crash would increase after compared to before surgery. METHODS: The authors performed a nested case-crossover study within population-based observational data from the New Jersey Safety Health Outcomes Data Warehouse. The study included adults 18 yr or older with a valid driver's license who underwent general surgery in an acute care hospital in New Jersey between January 1, 2016, and November 30, 2017, and were discharged home. Individuals served as their own controls within a presurgery interval (56 days to 28 days before surgery) and postsurgery interval (discharge through 28 days after surgery). General surgery was defined by Common Procedural Terminology Codes. The primary outcome was a police-reported motor vehicle crash. RESULTS: In a cohort of 70,722 drivers, the number of crashes after surgery was 263 (0.37%) compared to 279 (0.39%) before surgery. Surgery was not associated with a change in crash incidence greater than 28 days using a case-crossover design (adjusted incidence rate ratio, 0.92; 95% CI, 0.78 to 1.09; P = 0.340). Statistical interaction was present for sex and hospital length of stay. Younger versus older adults (adjusted risk ratio, 1.87; 95% CI, 1.10 to 3.18; P = 0.021) and non-Hispanic Black individuals (adjusted risk ratio, 1.96; 95% CI, 1.33 to 2.88; P = 0.001) and Hispanic individuals (adjusted risk ratio, 1.38; 95% CI, 1.00 to 1.91; P = 0.047) versus non-Hispanic White individuals had a greater risk of a crash after surgery. CONCLUSIONS: Using population-based crash and hospital discharge data, the incidence of motor vehicle crashes over a 28-day period did not change on average before compared to after surgery. The authors provide data on crash risk after surgery and highlight specific populations at risk.

SIGNIFICANCE: Eye tracking assessments that include pupil metrics can supplement current clinical assessments of vision and autonomic dysfunction in concussed adolescents. PURPOSE: This study aimed to explore the utility of a 220-second eye tracking assessment in distinguishing eye position, saccadic movement, and pupillary dynamics among uninjured adolescents, those with acute post-concussion symptoms (≤28 days since concussion), or those with persistent post-concussion symptoms (>28 days since concussion). METHODS: Two hundred fifty-six eye tracking metrics across a prospective observational cohort of 180 uninjured adolescents recruited from a private suburban high school and 224 concussed adolescents, with acute or persistent symptoms, recruited from a tertiary care subspecialty concussion care program, 13 to 17 years old, from August 2017 to June 2021 were compared. Kruskal-Wallis tests were used, and Bonferroni corrections were applied to account for multiple comparisons and constructed receiver operating characteristic curves. Principal components analysis and regression models were applied to determine whether eye tracking metrics can augment clinical and demographic information in differentiating uninjured controls from concussed adolescents. RESULTS: Two metrics of eye position were worse in those with concussion than uninjured adolescents, and only one metric was significantly different between acute cases and persistent cases. Concussed adolescents had larger left and right mean, median, minimum, and maximum pupil size than uninjured controls. Concussed adolescents had greater differences in mean, median, and variance of left and right pupil size. Twelve metrics distinguished female concussed participants from uninjured; only four were associated with concussion status in males. A logistic regression model including clinical and demographics data and transformed eye tracking metrics performed better in predicting concussion status than clinical and demographics data alone. CONCLUSIONS: Objective eye tracking technology is capable of quickly identifying vision and pupillary disturbances after concussion, augmenting traditional clinical concussion assessments. These metrics may add to existing clinical practice for monitoring recovery in a heterogeneous adolescent concussion population.

OBJECTIVE: To evaluate the discriminatory ability of different repetition increments of saccades and gaze stability testing for diagnosing concussion in adolescents. DESIGN: Cross-sectional. SETTING: Suburban high school and academic pediatric tertiary care center. PARTICIPANTS: Sixty-nine adolescent athletes within 28 days of a sports- or recreation-related concussion and 69 adolescent athletes without recent concussion. ASSESSMENT OF INDEPENDENT VARIABLES: Symptom provocation with horizontal and vertical saccades and gaze stability testing performed up to 30 repetitions. MAIN OUTCOME MEASURES: Sensitivity and specificity at 10-repetition increments (≤10, ≤20, ≤30) and area under the receiver operating characteristic curves (AUC) of a visio-vestibular examination (VVE) subscore, scored 0 to 4 based on the number of assessments with symptom provocation, at each repetition increment. RESULTS: Sensitivity improved when increasing from ≤10 to ≤20 to ≤30 repetitions for horizontal (25% to 50% to 69%) and vertical (32% to 52% to 74%) saccades and horizontal (19% to 45% to 71%) and vertical (23% to 45% to 72%) gaze stability. Specificity was comparable at ≤10 and ≤20 repetitions, but decreased at ≤30 repetitions across assessments. For a VVE subscore (0-4) based on the number of symptomatic assessments, the discriminatory ability of the test was highest at ≤20 repetitions (AUC of 0.79) with an optimal subscore of one (sensitivity 59%, specificity 96%). CONCLUSIONS: A VVE including a higher threshold level of repetitions for saccades and gaze stability has improved discriminatory ability for concussion, with an optimized AUC of 0.79 at ≤20 repetitions. CLINICAL RELEVANCE: The findings in this study suggest that a higher threshold level of repetitions of 2 commonly used visio-vestibular assessments enables clinicians to more accurately diagnose youth concussion.

In 30 states, licensing agencies can restrict the distance from home that "medically-at-risk" drivers are permitted to drive. However, where older drivers crash relative to their home or how distance to crash varies by medical condition is unknown. Using geocoded crash locations and residential addresses linked to Medicare claims, we describe how the relationship between distance from home to crash varies by driver characteristics. We find that a majority of crashes occur within a few miles from home with little variation across driver demographics or medical conditions. Thus, distance restrictions may not reduce crash rates among older adults, and the tradeoff between safety and mobility warrants consideration.
RESUMEN
OBJECTIVE: Our objective was to describe the development of the New Jersey Safety and Health Outcomes (NJ-SHO) data warehouse-a unique and comprehensive data source that integrates state-wide administrative databases in NJ to enable the field of injury prevention to address critical, high-priority research questions. METHODS: We undertook an iterative process to link data from six state-wide administrative databases from NJ for the period of 2004 through 2018: (1) driver licensing histories, (2) traffic-related citations and suspensions, (3) police-reported crashes, (4) birth certificates, (5) death certificates and (6) hospital discharges (emergency department, inpatient and outpatient). We also linked to electronic health records of all NJ patients of the Children's Hospital of Philadelphia network, census tract-level indicators (using geocoded residential addresses) and state-wide Medicaid/Medicare data. We used several metrics to evaluate the quality of the linkage process. RESULTS: After the linkage process was complete, the NJ-SHO data warehouse included linked records for 22.3 million distinct individuals. Our evaluation of this linkage suggests that the linkage was of high quality: (1) the median match probability-or likelihood of a match being true-among all accepted pairs was 0.9999 (IQR: 0.9999-1.0000); and (2) the false match rate-or proportion of accepted pairs that were false matches-was 0.0063. CONCLUSIONS: The resulting NJ-SHO warehouse is one of the most comprehensive and rich longitudinal sources of injury data to date. The warehouse has already been used to support numerous studies and is primed to support a host of rigorous studies in the field of injury prevention.

OBJECTIVE: The aim of the study was to comprehensively describe the natural history of concussion in early childhood between 0 and 4 years. METHODS: Retrospective cohort study of 329 patients aged 0 to 4 years, with an International Classification of Diseases, Ninth Revision, concussion diagnosis in the Children's Hospital of Philadelphia healthcare network from October 1, 2013, to September 30, 2015. Clinical data were abstracted from the Children's Hospital of Philadelphia electronic health record, which captured all clinical care visits and injury characteristics. RESULTS: Nearly 9 (86.6%) of 10 patients sought care in the emergency department or urgent care setting, most commonly on the day of injury (56.2%) and as a result of a fall (64.4%). More than two-thirds (64.4%) of patients or their parent/caregiver reported somatic symptoms (ie, vomiting or headache), whereas close to half (49.2%) reported sleep issues. One of 5 patients identified emotional symptoms (21.9%) or visio-vestibular dysfunction (20.4%). Many patients also experienced symptoms not included in standard assessment tools including personality changes (34.0%) and change in appetite (12.8%). CONCLUSIONS: These results provide insight into the clinical characteristics of concussion in early childhood up to 4 years of age. Because assessment in this group relies heavily on parent/caregiver symptom reporting, rather than patient self-report, these results will aid clinicians with the challenge of diagnosing concussions in this population. These findings highlight the need to develop additional tools to adequately and systematically assess common signs and symptoms of concussion in early childhood that may not be included in standard assessment scales routinely used in older adolescents and adults.

INTRODUCTION: Motor vehicle crashes are the leading cause of adolescent death. Inattention to the roadway contributes to crash risk. The objective of this study was to deploy an initial study of a web-based intervention (Let's Choose Ourselves) designed to improve adolescent driver attention to the roadway. METHODS: We used a randomized controlled trial design in a sample of adolescent drivers to test if a web-based intervention decreased cell phone engagement in driving simulation at 3 months as compared with controls. As secondary hypotheses, we tested if the intervention increased the use of peer passengers to manage distractions and decreased eyes off the forward roadway in driving simulation and decreased self-reported risky driving behaviors. Adolescents, aged 16-17 years, licensed for ≤90 days were randomized to Let's Choose Ourselves with distractions in the simulator protocol at baseline, Let's Choose Ourselves with no distractions, an attention control intervention on healthy eating with distractions, or attention control with no distractions. We used Poisson regression modeling to test the primary and secondary hypotheses. RESULTS: The trial included 60 adolescents (66.7% female, 78.3% non-Hispanic white subjects, mean age 16.8 years, licensed 50.8 days). In Poisson regression, controlling for sex, we found no significant effects of Let's Choose Ourselves on primary or secondary outcomes. However, there was a significant effect of visit on self-report outcomes, with self-reported distracted driving behaviors increasing over time. DISCUSSION: Although there were no significant effects of Let's Choose Ourselves, self-reported risky driving behaviors increased over time. Further investigation of the relationship between driving experience and increasing inattention to the road in adolescents is warranted.

OBJECTIVE: To comprehensively characterize the clinical presentation and course of care for concussion among 5- to 11-year-old children, identifying preinjury and injury factors potentially influencing clinical outcomes. STUDY DESIGN: A single-institution retrospective cohort study using electronic health record data from children ages 5- to 11 years with a concussion from July 1, 2014, through June 30, 2015. Electronic health record data were abstracted for a 20% random sample of 292 patients. RESULTS: Three-fourths of patients (74.3%) presenting for concussion care had a standardized visiovestibular assessment performed. Almost all of those who eventually sought specialty care (92.9%) also had such an assessment, and only 42.9% patients initially seen in the emergency department or urgent care were examined in this manner. Of those assessed, 62.7% (n = 136) demonstrated deficits, with children ages 9-11 years more frequently exhibiting deficits than their younger counterparts (67.9% vs 53.2%; P = .03). Almost all patients (95.9%) reported at least 1 somatic symptom (eg, headache, dizziness), and one-half to two-thirds reported problems with sleep (54.1%) and visiovestibular symptoms (66.1%). Only 11.6% of children were referred for rehabilitation therapies and less than one-half of concussed patients (43.8%) were provided with a letter recommending school accommodations. CONCLUSIONS: Somatic symptoms, sleep problems, and visiovestibular deficits are common in elementary school-aged children with concussion, but specific visiovestibular clinical assessments are often not performed, particularly in the emergency department setting. Recommendations for school accommodations are often not provided at the time of concussion diagnosis. Incorporating a standardized visiovestibular assessment into practice could facilitate early targeted school accommodations and thereby improve return to learning for elementary school-aged children with concussion.

BACKGROUND: Despite substantial progress, motor vehicle crashes remain a leading killer of US children. Previously, we documented significant positive impacts of Safe Routes to School interventions on school-age pedestrian and pedalcyclist crashes. OBJECTIVE: To expand our analysis of US trends in motor vehicle crashes involving school-age pedestrians and pedalcyclists, exploring heterogeneity by age and geography. METHODS: We obtained recent police-reported crash data from 26 states, calculating population rates of pedestrian and pedalcyclist crashes, crash fatality rates and pedestrian commuter-adjusted crash rates ('pedestrian danger index') for school-age children as compared with other age groups. We estimated national and statewide trends by age, injury status, day and travel hour using hierarchical linear modeling. RESULTS: School-age children accounted for nearly one in three pedestrians and one in two pedalcyclists struck in motor vehicle crashes from 2000 to 2014. Yet, the rates of these crashes declined 40% and 53%, respectively, over that time, on average, even as adult rates rose. Average crash rates varied geographically from 24.4 to 100.8 pedestrians and 15.6 to 56.7 pedalcyclists struck per 100 000 youth. Crash rates and fatality rates were inversely correlated. CONCLUSIONS: Despite recent increases in adult pedestrian crashes, school-age and younger pedestrians experienced ongoing declines in motor vehicle crashes through 2014 across the USA. There was no evidence of displacement in crash severity; declines were observed in all outcomes. The growing body of state crash data resources can present analytic challenges but also provides unique insights into national and local pedestrian crash trends for all crash outcomes.

OBJECTIVE: To quantify the risk of repeat concussions for children and identify demographic and clinical aspects of the index concussion associated with repeat injury. STUDY DESIGN: For this retrospective cohort study, we queried the Children's Hospital of Philadelphia healthcare network's unified electronic health record to identify all 5- to 15-year-old patients who had their first clinical visit for an index concussion at a Children's Hospital of Philadelphia location from July 2012 through June 2013. A 25% random sample (n = 536) were selected. Clinical data were abstracted for their index concussion and all concussion-related visits for 2 years following the index concussion. RESULTS: Overall, 16.2% (n = 87) of patients experienced at least 1 repeat concussion within 2 years of their index concussion. The risk of repeat concussion increased with patient age (9.5% for ages 5-8 years; 10.7% for ages 9-11 years; and 19.8% for ages 12-15 years). After we adjusted for other factors, risk was particularly heightened among patients whose index concussion had a longer clinical course (>30 vs 0-7 days, adjusted risk ratio 1.65 [1.01-2.69]) and greater symptom burden (>11 vs 0-2 symptoms, adjusted risk ratio 2.12 [1.12-3.72]). CONCLUSIONS: We estimate that 1 in 6 youth diagnosed with a concussion are diagnosed with a subsequent concussion within 2 years and that several clinical characteristics of the index concussion increase this risk. Identifying factors associated with a repeat injury is essential to inform the clinical management of concussion and direct injury prevention efforts.

OBJECTIVES: To assess the distribution of injury mechanisms and activities among children with concussions in a large pediatric healthcare system. STUDY DESIGN: All patients, age 0-17 years, who had at least 1 clinical encounter with an International Classification of Diseases, Ninth Revision, Clinical Modification diagnosis of concussion in the Children's Hospital of Philadelphia's electronic health record system from July 1, 2012 to June 30, 2014, were selected (N = 8233) and their initial concussion-related visit identified. Approximately, 20% of the patients (n = 1625) were randomly selected for manual record review to examine injury mechanisms and activities. RESULTS: Overall, 70% of concussions were sports related; however, this proportion varied by age. Only 18% of concussions sustained by children aged 0-4 were sports related, compared with greater proportions for older children (67% for age 5-11, 77% for age 12-14, and 73% for age 15-17). When the concussion was not sports related, the primary mechanisms of injury were struck by an object (30%) and falls (30%). CONCLUSIONS: Sports-related injuries in children older than 6 years of age contributed to the majority of concussions in this cohort; however, it is important to note that approximately one-third of concussions were from non-sports-related activities. Although there is increased participation in community and organized sports activities among children, a focus on prevention efforts in other activities where concussions occur is needed.

OBJECTIVES: To describe the disposition of young children diagnosed with physical abuse in the emergency department (ED) setting and identify factors associated with the decision to discharge young abused children. STUDY DESIGN: We performed a retrospective cross-sectional study of children less than 2 years of age diagnosed with physical abuse in the 2006-2012 Nationwide Emergency Department Sample. National estimates were calculated accounting for the complex survey design. We developed a multivariable logistic regression model to evaluate the relationship between payer type and discharge from the ED compared with admission with adjustment for patient and hospital factors. RESULTS: Of the 37 655 ED encounters with a diagnosis of physical abuse among children less than 2 years of age, 51.8% resulted in discharge, 41.2% in admission, 4.3% in transfer, 0.3% in death in the ED, and 2.5% in other. After adjustment for age, sex, injury type, and hospital characteristics (trauma designation, volume of young children, and hospital region), there were differences in discharge decisions by payer and injury severity. The adjusted percentage discharged of publicly insured children with minor/moderate injury severity was 56.2% (95% CI 51.6, 60.7). The adjusted percentages discharged were higher for both privately insured children at 69.9% (95% CI 64.4, 75.5) and self-pay children at 72.9% (95% CI 67.4, 78.4). The adjusted percentages discharged among severely injured children did not differ significantly by payer. CONCLUSIONS: The majority of ED visits for young children diagnosed with abuse resulted in discharge. The notable differences in disposition by payer warrant further investigation.

BACKGROUND: While concussions are common pediatric injuries, a lack of agreement on a standard definition of recovery creates multiple challenges for clinicians and researchers alike. HYPOTHESIS: The percentage of concussed youth deemed recovered as part of a prospective cohort study will differ depending on the recovery definition. STUDY DESIGN: Descriptive epidemiologic study of a prospectively enrolled observational cohort. LEVEL OF EVIDENCE: Level 3. METHODS: Participants aged 11 to 18 years were enrolled from the concussion program of a tertiary care academic center. Data were collected from initial and follow-up clinical visits ≤12 weeks from injury. A total of 10 recovery definitions were assessed: (1) cleared to full return to sports; (2) return to full school; (3) self-reported return to normal; (4) self-reported full return to school; (5) self-reported full return to exercise; (6) symptom return to preinjury state; (7) complete symptom resolution; (8) symptoms below standardized threshold; (9) no abnormal visio-vestibular examination (VVE) elements; and (10) ≤1 abnormal VVE assessments. RESULTS: In total, 174 participants were enrolled. By week 4, 63.8% met at least 1 recovery definition versus 78.2% by week 8 versus 88.5% by week 12. For individual measures of recovery at week 4, percent recovered ranged from 5% by self-reported full return to exercise to 45% for ≤1 VVE abnormality (similar trends at 8 and 12 weeks). CONCLUSION: There is wide variability in the proportion of youth considered recovered at various points following concussion depending on the definition of recovery, with higher proportions using physiologic examination-based measures and lower proportions using patient-reported measures. CLINICAL RELEVANCE: These results further emphasize the need for a multimodal assessment of recovery by clinicians as a single and standardized definition of recovery that captures the broad impact of concussion on a given patient continues to be elusive.

Importance: Mood disorders are prevalent among adolescents and young adults, and their onset often coincides with driving eligibility. The understanding of how mood disorders are associated with youth driving outcomes is limited. Objective: To examine the association between the presence of a mood disorder and rates of licensing, crashes, violations, and suspensions among adolescents and young adults. Design, Setting, and Participants: This cohort study was conducted among New Jersey residents who were born 1987 to 2000, age eligible to acquire a driver's license from 2004 to 2017, and patients of the Children's Hospital of Philadelphia network within 2 years of licensure eligibility at age 17 years. The presence of a current (ie, ≤2 years of driving eligibility) mood disorder was identified using International Classification of Diseases, Ninth Revision, Clinical Modification (ICD-9-CM) or International Statistical Classification of Diseases, Tenth Revision, Clinical Modification (ICD-10-CM) codes. Rates of licensure and driving outcomes among youths who were licensed were compared among 1879 youths with and 84â¯294 youths without a current mood disorder from 2004 to 2017. Data were analyzed from June 2022 to July 2023. Main Outcomes and Measures: Acquisition of a driver's license and first involvement as a driver in a police-reported crash and rates of other adverse driving outcomes were assessed. Survival analysis was used to estimate adjusted hazard ratios (aHRs) for licensing and driving outcomes. Adjusted rate ratios (aRRs) were estimated for driving outcomes 12 and 48 months after licensure. Results: Among 86â¯173 youths (median [IQR] age at the end of the study, 22.8 [19.7-26.5] years; 42â¯894 female [49.8%]), there were 1879 youths with and 84â¯294 youths without a mood disorder. A greater proportion of youths with mood disorders were female (1226 female [65.2%]) compared with those without mood disorders (41â¯668 female [49.4%]). At 48 months after licensure eligibility, 75.5% (95% CI, 73.3%-77.7%) and 83.8% (95% CI, 83.5%-84.1%) of youths with and without mood disorders, respectively, had acquired a license. Youths with mood disorders were 30% less likely to acquire a license than those without a mood disorder (aHR, 0.70 [95% CI, 0.66-0.74]). Licensed youths with mood disorders had higher overall crash rates than those without mood disorders over the first 48 months of driving (137.8 vs 104.8 crashes per 10â¯000 driver-months; aRR, 1.19 [95% CI, 1.08-1.31]); licensed youths with mood disorders also had higher rates of moving violations (aRR, 1.25 [95% CI, 1.13-1.38]) and license suspensions (aRR, 1.95 [95% CI, 1.53-2.49]). Conclusions and Relevance: This study found that youths with mood disorders were less likely to be licensed and had higher rates of adverse driving outcomes than youths without mood disorders. These findings suggest that opportunities may exist to enhance driving mobility in this population and elucidate the mechanisms by which mood disorders are associated with crash risk.

INTRODUCTION: Prior work has found incongruencies in injury information reported by crash and hospital records. However, no work has focused on child passengers. The objective of this study was to compare crash scene and hospital-reported injury information for crash-involved child passengers. This study also explored injury location and severity by child age and restraint type. METHODS: Utilizing linked New Jersey data from 2017 through 2019, the authors identified crash-involved child passengers <13 years old and their injuries in crash and hospital reports. Then, they characterized the congruency of injury frequency, severity, and location, as well as the frequency of injuries by child age and restraint type. Analyses were conducted from December 2023 through February 2024. RESULTS: Of 84,060 crash-involved child passengers, crash reports documented 7,858 (9%) children with at least "possible" injuries, while 2,577 (3%) had at least one injury in hospital events. Crash report and hospital data were incongruent for both body region of injury and injury severity. The proportion of children injured increased as children's ages increased and as restraint type progressed. CONCLUSIONS: Crash reports overestimated the number of injured child passengers and misrepresented injury severity and locations. Child restraint systems mitigated a child's injury risk. Importantly, injury information documented on crash reports currently informs the allocation of traffic safety resources. These results highlight the importance of improving these reports' accuracy and underscore calls to link administrative datasets for public health efforts.
RESUMEN
Concussion is a common injury in the adolescent and young adult populations. Although branched chain amino acid (BCAA) supplementation has shown improvements in neurocognitive and sleep function in pre-clinical animal models of mild-to-moderate traumatic brain injury (TBI), to date, no studies have been performed evaluating the efficacy of BCAAs in concussed adolescents and young adults. The goal of this pilot trial was to determine the efficacy, tolerability, and safety of varied doses of oral BCAA supplementation in a group of concussed adolescents and young adults. The study was conducted as a pilot, double-blind, randomized controlled trial of participants ages 11-34 presenting with concussion to outpatient clinics (sports medicine and primary care), urgent care, and emergency departments of a tertiary care pediatric children's hospital and an urban tertiary care adult hospital, between June 24, 2014 and December 5, 2020. Participants were randomized to one of five study arms (placebo and 15 g, 30 g, 45 g, and 54 g BCAA treatment daily) and followed for 21 days after enrollment. Outcome measures included daily computerized neurocognitive tests (processing speed, the a priori primary outcome; and attention, visual learning, and working memory), symptom score, physical and cognitive activity, sleep/wake alterations, treatment compliance, and adverse events. In total, 42 participants were randomized, 38 of whom provided analyzable data. We found no difference in our primary outcome of processing speed between the arms; however, there was a significant reduction in total symptom score (decrease of 4.4 points on a 0-54 scale for every 500 g of study drug consumed, p value for trend = 0.0036, [uncorrected]) and return to physical activity (increase of 0.503 points on a 0-5 scale for every 500 g of study drug consumed, p value for trend = 0.005 [uncorrected]). There were no serious adverse events. Eight of 38 participants reported a mild (not interfering with daily activity) or moderate (limitation of daily activity) adverse event; there were no differences in adverse events by arm, with only two reported mild adverse events (both gastrointestinal) in the highest (45 g and 54 g) BCAA arms. Although limited by slow enrollment, small sample size, and missing data, this study provides the first demonstration of efficacy, as well as safety and tolerability, of BCAAs in concussed adolescents and young adults; specifically, a dose-response effect in reducing concussion symptoms and a return to baseline physical activity in those treated with higher total doses of BCAAs. These findings provide important preliminary data to inform a larger trial of BCAA therapy to expedite concussion recovery.

RESEARCH QUESTION/OBJECTIVE: In the US, child fatalities in hot cars [i.e., pediatric vehicular heatstroke (PVH)] occur on average once every 10 days. Despite national campaigns and recurring media attention, there has been little change in the rate of PVH deaths annually. The objective of this study was to characterize caregivers' beliefs, behaviors, and attitudes related to PVH risk factors and potential mitigating technologies. METHODS/DATA SOURCES: We conducted a national survey of US caregivers to: (1) determine caregivers' perceptions of PVH risk for children in their care, as well as their thoughts about adopting risk mitigating technologies, (2) characterize scenarios in which caregivers intentionally leave children unattended in vehicles, and (3) assess caregiver awareness of national PVH campaigns. We used a variety of question formats (select all that apply, multiple choice, free response). Data were analyzed data using descriptive statistics and caregiver responses related to PVH event behaviors were compared across selected demographic characteristics using chi-square tests. RESULTS: Exactly 1,500 caregivers completed the survey; 60% were female and 60% were non-Hispanic White. Most, or 88%, of our respondents reported they do not leave their child(ren) alone in vehicles for any amount of time. However, there were differences in who engages in this behavior by caregivers' gender, education, income, and number of children. Few, or 12%, believed they were at any risk for having a child overheat in a vehicle, and most caregivers described negative and/or judgmental views of those who were at-risk. Nearly all participants indicated it was important that caregivers receive education about PVH (95%), and the majority, or 90%, responded they would be willing to adopt risk mitigating technology themselves, many believing they and others would be perceived as better caregivers if they did so. SIGNIFICANCE OF RESULTS: This is the first nationally representative study to the authors' knowledge that characterizes caregivers' attitudes, behaviors, and perceived risk of PVH, along with their willingness to adopt mitigating technologies. Our dissonant finding that caregivers view those who may be at risk for PVH negatively while simultaneously viewing those who adopt risk mitigating strategies positively provides stakeholders with unique insight for future efforts. Specifically, messaging utilizing themes of positive caregiving might be more effective at increasing caregivers' adoption than threat-based campaigns focused on communicating risk. Additionally, our findings of demographic differences in behaviors related to PVH are a helpful first step to inform the development of tailored interventions (e.g., public messaging) and potential risk mitigating technologies that may be more likely to be widely adopted.

BACKGROUND: Few studies have examined psychiatric symptoms during the acute phase following a concussion in adolescents. Thus, this study compares anxiety and depression in acutely concussed and nonconcussed adolescents. HYPOTHESIS: Acutely concussed adolescents will report greater anxiety and depressive symptoms compared with nonconcussed adolescents. STUDY DESIGN: Prospective cohort study. LEVEL OF EVIDENCE: Level 3. METHODS: Data were collected from 282 adolescents (111 concussed within 28 days of injury, 171 nonconcussed), 13 to 18 years of age, who completed Patient-Reported Outcome Measurement Information System (PROMIS) Anxiety and Depressive Symptoms measures. We calculated average T-scores for anxiety and depression across both groups and compared the proportion of those who scored above normal limits. Finally, we calculated risk ratios for anxiety and depression scores above normal limits. RESULTS: Average T-scores for anxiety did not differ in concussed versus nonconcussed adolescents (mean: 45.9 [SD 10.84] vs 45.2 [8.1], respectively, P = 0.54), whereas average T-scores for depression were significantly higher in concussed versus nonconcussed adolescents (46.0 [10.88] vs 42.8 [8.48], respectively, P < 0.01). The proportion of concussed adolescents above normal limits for depression was greater than nonconcussed adolescents (32.4% vs 20.5%, respectively, P = 0.02). Post hoc sensitivity analyses excluding those with a history of anxiety or depression demonstrated a 1.45 (95% CI, 0.97, 2.01) and 1.56 (95% CI, 0.95, 2.56) increased risk of an above-normal anxiety and depression score for concussed compared with nonconcussed adolescents, respectively, although both were nonsignificant. CONCLUSION: Although we found few significant differences between the 2 groups, the results highlight that many concussed adolescents met the threshold for above-average symptoms on the depression and anxiety PROMIS measures. CLINICAL RELEVANCE: In adolescents, there is increased risk for psychiatric sequalae in the acute period after a concussion. As such, we suggest that clinicians consider incorporating depression screening when caring for adolescents after a concussion.

INTRODUCTION: Examining crash reports with linked community-level indicators may optimize efforts aimed at improving traffic safety behaviors, like seat belt use. To examine this, quasi-induced exposure (QIE) methods and linked data were used to (a) estimate trip-level seat belt non-use of New Jersey (NJ) drivers and (b) determine the degree to which seat belt non-use is associated with community-level indicators of vulnerability. METHOD: Driver-specific characteristics were identified from crash reports (age, sex, number of passengers, vehicle type) and licensing data (license status at the time of the crash). Geocoded residential addresses were leveraged within the NJ Safety and Health Outcomes warehouse to create quintiles of community-level vulnerability. QIE methods were applied to estimate trip-level prevalence of seat belt non-use in non-responsible, crash-involved drivers between 2010-2017 (nâ¯=â¯986,837). Generalized linear mixed models were then conducted to calculate adjusted prevalence ratios and 95â¯% confidence intervals for being unbelted for driver-specific variables and community-level indicators of vulnerability. RESULTS: Drivers were unbelted during 1.2â¯% of trips. Males, those with suspended licenses, and those without passengers had higher rates of being unbelted than their counterparts. An increase was observed in traveling unbelted with increasing quintiles of vulnerability, such that drivers in the most vulnerable communities were 121â¯% more likely to be unbelted than those in the least vulnerable communities. CONCLUSIONS: Prevalence of driver seat belt non-use may be lower than previously estimated. Additionally, communities with the highest amount of the population living with three or more indicators of vulnerability have higher rates of seat belt non-use; this may be a particularly useful metric to inform future translational efforts improving seat belt use. PRACTICAL APPLICATIONS: As evidenced by the findings that risk of being unbelted increased as drivers' community vulnerability increased, novel communication efforts tailored to drivers from vulnerable neighborhoods may optimize efforts.

PURPOSE: Marginalized and otherwise vulnerable groups remain at higher risk than their counterparts for not having all of their children appropriately restrained during vehicle trips. Little is known about potential sources of these disparities, however a commonly theorized factor has been where caregivers find or obtain information (i.e., their information sources). The objective of this study was to: (1) characterize caregivers' actual and preferred sources of information related to child passenger safety information, overall and within sociodemographic groups; and (2) determine if, and if so how, sources impact appropriate child restraint use (i.e., child/seat fit). METHODS: We conducted an online, cross-sectional survey of US caregivers. Caregivers answered questions about themselves, their child(ren), their child(ren)'s restraint use during trips, and their information sources to learn which seat their child should be using. We used Fisher's exact and Pearson chi-square tests to compare used and preferred sources of information across caregiver demographics (age, education, race/ethnicity), as well as to determine whether information sources were associated with caregivers' appropriate child restraint use. RESULTS: A total of 1,302 caregivers from 36 states with 2,092 children completed the survey. The majority (91%) of children were appropriately restrained. More caregivers from marginalized and otherwise vulnerable groups had children inappropriately restrained when compared with their counterparts. We identified multiple differences in both used and preferred information sources by caregivers' age, race/ethnicity, and education level. In addition, we found a trend that caregivers from populations with higher rates of inappropriate use seemingly used fewer information sources. Ultimately, information sources were not associated with appropriate restraint use; however, within vulnerable populations, almost all caregivers had all of their children appropriately restrained if they had used a Child Passenger Safety Technician (CPST)/Inspection Station or their Pediatrician. CONCLUSION: Our findings reiterate calls for more tailored interventions and efforts to combat widening disparities in child restraint use and crash outcomes and suggest one promising method may be providing more access to child passenger safety experts. Future studies must untangle the likely complex relationship between information sources and appropriate/accurate child restraint use.
