The association between county ordinances allowing off-road vehicles on public roads and crash rates.

BACKGROUND: Legislative bodies across the country have increasingly allowed off-road vehicles (ORVs) including all-terrain vehicles (ATVs) and utility task vehicles (UTVs) on public roads, an environment for which they are not designed. In 2004, Iowa gave individual counties the discretion to pass ordinances allowing ORVs on public roadways. The objective of this study was to evaluate the relationship between the passage of ORV ordinances and ORV crash rates, especially on public roads. METHODS: An Iowa ORV roadway ordinance database and an Iowa ORV crash database (2002-2018) for all 99 counties were compiled. Crashes for which county location could not be determined were excluded. Utilizing a zero-inflated Poisson model, correcting for background crash frequency trends and population, investigators compared the relative rates of crashes after ordinance passage to time points before ordinance implementation and to counties without such ordinances. Sub-analyses, including that focused on more recent years (2008-2018), were also performed. RESULTS: Forty-five county ORV roadway ordinances went into effect between 2011 and 2018 and 2,347 crashes (69%) met inclusion criteria. Adjusted for year, there was a 58% greater ORV crash rate in counties after passing an ORV roadway ordinance (incidence rate ratio (IRR) 1.58, 95% CI 1.32-1.90). Roadway crashes (n = 834) increased 48% after ordinance passage (IRR 1.48, 95% CI 1.14-1.94). This roadway crash association remained statistically significant when analysis was limited to the years 2008-2018 (IRR 1.39, CI 1.06-1.83, n = 544); to ATV crashes only (IRR 1.70, CI 1.20-2.40, n = 683); and to ATV crashes excluding counties with UTV-only ordinances (IRR 1.74, CI 1.40-2.15, n = 2,011). CONCLUSIONS: ORV roadway and total crashes increased significantly after implementation of county ordinances allowing ORVs on public roadways and when compared to counties without such ordinances. It is likely that these increased crashes have resulted in more injuries and possibly deaths. Results from this study may help inform policymakers as they consider legislation regarding ORV usage on public roads.

Firearm exposure and safety training of rural Iowa youth.

PURPOSE: Our objective was to investigate rural adolescents' use of firearms and whether they had received firearm training. METHODS: 2019 Iowa FFA Leadership Conference attendees were surveyed. Descriptive and comparative analyses were performed. RESULTS: One thousand three hundred and eighty-two FFA members aged 13-18 years participated. The vast majority (85%) had fired a rifle/shotgun; 58% reported firing them >20 times. Of those who had fired rifles/shotguns, 32% had done so before 9 years old; 79% before 13 years. Most had also fired a handgun (62%), with 30% having fired handguns >20 times. Of those who had fired handguns, 34% had done so before 11 years old. The average age for first firing rifles/shotguns was 10.1 (SD 2.9) years, and 11.9 (SD 2.8) years for handguns. Males, older teenagers, and those living on farms or in the country had significantly greater percentages that had fired a rifle/shotgun or a handgun. Greater proportions of males had used firearms >20 times and started firing them at younger ages. Over half (55%) reported having gone hunting. Of those, 24% first hunted before 9 years old; 48% before 11 years. Of those who had used a firearm, 61% had completed a firearm safety training course. For hunters, 80% had taken a course. CONCLUSIONS: Most participants had used firearms, and many did so at very young ages. Substantial numbers had not received formal training. The authors believe that families should be counseled when it is developmentally appropriate to introduce youth to firearms, and all should take firearm safety training before using them.

Recreational off-highway vehicle exposure, safety behaviors and crash experiences among adolescents.

BACKGROUND: Recreational off-highway vehicles (ROVs), often called utility task vehicles (UTVs), are designed to be driven by those ≥ 16 years and manufacturers recommend passengers be at least 12 years old. This study's objective was to determine Iowa adolescents' exposure to ROVs, riders' use of restraint devices, and crash prevalence. METHODS: Adolescents participating in the Safety Tips for ATV Riders (STARs) program at their schools were anonymously surveyed by the Iowa Off-Road Vehicle Safety Task Force from Fall 2014-Fall 2019. Frequency, bivariate (chi square and Fisher's exact test) and logistic regression analyses were performed using SAS software, V.9.4. RESULTS: A total of 4,023 students (9-18 years) from 18 school districts participated. Overall, 68% reported having ridden in an ROV. The proportions having ridden an ROV by where participants lived were farm (85%) > country/not farm (73%) > town (60%), p < 0.0001. Of those asked additional ROV questions (n = 2152), 39% of ROV riders reported riding at least weekly in the previous 12 months. Of those riding ROVs in the past year, 29% reported having at least one crash. Males and respondents living on farms had higher percentages reporting crashes, as compared to females (31% vs. 24%, p = 0.005) and those living elsewhere (35% vs. 24%, p = 0.0003). Thirty-seven percent of ROV riders never or almost never wore their seatbelt. Seatbelt use was inversely proportional to age, p < 0.001. A higher proportion of females reported always or almost always wearing a seat belt (42% vs. 36%, p = 0.0016). Percentages never or almost never wearing seatbelts by residence were farm (47%) > country/not farm (38%) > town (32%), p = 0.0005. Almost daily riders and those reporting having been in a crash were both 1.7 times more likely to never or almost never wear a seatbelt as compared to infrequent riders and those without a crash, respectively. CONCLUSIONS: Iowa adolescents frequently ride ROVs and often without a seatbelt, putting them at greater risk for serious injury or death in a crash. Almost 30% of riders reported an ROV-related crash in the past year. Our study identified a high-risk population that could be targeted for ROV safety education and other injury prevention efforts.

All-terrain vehicle exposure and the association of certified training on adolescent safety behaviors and crash experiences.

BACKGROUND: Certified training courses in all-terrain vehicle (ATV) operation are recommended, but little has been published regarding how they affect riding behaviors. Our objectives were to determine adolescents' ATV riding exposures, crashes and injuries, and the association of completing certified ATV training on riding behaviors. METHODS: Respondents completed an anonymous paper survey at 30 school districts approximately one year after participating in the Safety Tips for ATV Riders (STARs) program. Survey data were compiled using Qualtrics™. Frequency, chi-square, Fisher's exact test, and logistic regression analyses were performed using SAS, V.9.4. RESULTS: 4,891 students completed the survey from Fall 2012-Fall 2019. Respondents were 10-18 years old, and similar numbers of participants were male and female. Fifty-nine percent lived in town, 18% on a farm, and 22% in the country but not on farm. Forty-two percent reported their families owned an ATV. Seventy-seven percent had ridden an ATV, 40% of whom reported riding at least weekly. The vast majority (94%) used ATVs for recreation and 49% used them for work purposes. In the previous year, 22% of riders reported having been in a crash, with 7% of crash victims requiring medical attention for injuries. Greater crash likelihood was seen in males, recreational riders, more frequent riders, competitive racers and those who had ridden with passengers or on roads. Only 8% of riders had completed certified ATV safety training (note, STARs is not a certification program). Those whose families owned ATVs, more frequent riders, and public park users had greater likelihoods of course completion. Relative to their peers, respondents who completed a certification course had higher proportions that always/almost always wore helmets (39% vs. 20%, p < 0.0001) and lower proportions that never/almost never wore helmets (29% vs 58%, p < 0.0001), had ridden with passengers (63% vs. 96%, p < 0.0001), and had driven on public roads (41% vs 50%, p = 0.0065). CONCLUSIONS: ATV safety training certification among Iowa adolescents in the study was infrequent but those that received training reported higher helmet use, less riding with passengers, and less driving on public roads. These data suggest completing safety training certification may promote safer riding behaviors among youth.

American Academy of Pediatrics Recommendations for the Prevention of Pediatric ATV-Related Deaths and Injuries.

Since all-terrain vehicles (ATVs) were introduced in the mid-1970s, regulatory agencies, injury prevention researchers, and pediatricians have documented their dangers to youth. Major risk factors, crash mechanisms, and injury patterns for children and adolescents have been well characterized. Despite this knowledge, preventing pediatric ATV-related deaths and injuries has proven difficult and has had limited success. This policy statement broadly summarizes key background information and provides detailed recommendations based on best practices. These recommendations are designed to provide all stakeholders with strategies that can be used to reduce the number of pediatric deaths and injuries resulting from youth riding on ATVs.

A Comprehensive Report on All-Terrain Vehicles and Youth: Continuing Challenges for Injury Prevention.

All-terrain vehicles (ATVs) represent a serious and ongoing public health and safety concern for children and adolescents. Survey studies indicate that high proportions of youth ride ATVs in both rural and nonrural populations. The significant human and economic costs of pediatric ATV-related deaths and injuries result from a number of major risk factors that are highly common in pediatric ATV crashes: operating adult-size vehicles, riding with or as passengers, lack of protective equipment, and riding on public roads. Other less well-studied but potentially significant risk factors are speed, riding at night, alcohol use among older teenagers, and lack of training and supervision. Although potentially safer than adult ATVs, youth models present a number of safety concerns that have not been addressed with rigorous study. The most common ATV crash mechanism is a noncollision event-for example, a rollover. Common injury mechanisms include ejection from the vehicle, resulting in extremity and head injuries, and being pinned or crushed by the vehicle with resulting multiorgan trauma and/or compression asphyxia. Traumatic brain injury and multisystem trauma are the 2 most common causes of death and disabling injury. Taken together, a large multidecade body of evidence is the basis for the American Academy of Pediatrics policy statement recommendation that no child younger than 16 years of age ride on an ATV. Because children continue to be allowed to ride these vehicles, however, efforts to prevent pediatric ATV-related deaths and injuries require multipronged strategies, including education of both youth and parents, safety-based engineering, and enforcement of evidence-based safety laws.

Rural youth's exposure to firearm violence and their attitudes regarding firearm safety measures.

BACKGROUND: In the wake of an epidemic in firearm-related deaths and injuries, youth have become leading voices of concern. This study's objective was to investigate rural youth's personal experiences with firearm-related violence, and their attitudes towards firearms and gun violence prevention strategies. METHODS: Attendees of the 2019 Iowa FFA Leadership Conference were surveyed about personal experiences with firearm-associated deaths and injuries, and their attitudes regarding firearm-related issues. Descriptive (frequencies), bivariate (chi square, Fisher's exact test) and multivariable logistic regression analyses were performed utilizing Stata 15.1 (StataCorp, College Station, Texas). RESULTS: Responses from 1382 FFA members 13-18 years of age were analyzed. About 5% had personally seen someone threatened with a firearm. Over one-third (36%) stated they knew someone who had been killed or injured by gunfire. Of these, over two-thirds knew of someone who had died or was injured unintentionally and 30% knew of someone killed or injured intentionally (e.g. suicide). Nearly all agreed or strongly agreed that the right to use firearms for hunting and shooting sports should be legal (94%), that a firearm safety course should be required to get a hunting license (89%), and that there should be a required background check before purchasing a firearm (89%). Over three-fifths (61%) agreed or strongly agreed that there should be laws requiring safe storage of firearms in homes. Although still high, lesser support for firearm safety policies was seen among males, older youth, participants living on farms or in the country, and youth who hunted, had firearms in their homes, and/or were in homes with unsafe firearm storage. CONCLUSIONS: The majority of youth in this study supported firearm safety measures including required training, background checks, and safe firearm storage in homes. These findings are consistent with the national youth-led call for firearm safety. Additionally, over one-third of respondents personally knew someone who was killed or injured by a firearm and 5% had seen someone or been personally threatened with firearm violence. Our study did not investigate the effects of firearm violence on participants' mental health and wellbeing, but future studies addressing this question seem highly justified.

The dark side of nighttime all-terrain vehicle use.

BACKGROUND: Driving at night is considered a risk factor for all-terrain vehicle (ATV) crashes and injuries but few studies have addressed this issue. Our objective was to compare daytime and nighttime ATV crashes to better understand the potential risk factors associated with riding at night. METHODS: A retrospective study was conducted on Iowa ATV-related crashes and injuries from January 1, 2002 through December 31, 2019 using four statewide datasets: the Iowa Department of Transportation (2002-2019), the Iowa Department of Natural Resources (2002-2019), the Iowa State Trauma Registry (2002-2018) and Iowa newspaper clippings (2009-2019). A standardized coding system was developed, and matching records were identified using Link Plus®. Descriptive (frequencies) and bivariate (chi-square, Fisher's exact test) analyses were performed using VassarStats (Statistical Computation Website). RESULTS: Among crash victims where light conditions were documented (2125/3752, 57%), about one-quarter (485/2125, 23%) were injured at night. Nighttime crash victims were less likely youth (14% vs. 30%, p < 0.0001), less likely to be wearing helmets (11% vs. 18%, p = 0.003), and less frequently involved in motor vehicle crashes (7% vs. 14%, p < 0.0001) as compared to daytime victims. Nighttime victims were also more likely to be passengers (22% vs. 15%, p = 0.002), to test positive for alcohol (44% vs. 13% in adults, p < 0.0001), and to be injured on a roadway (53% vs. 45%, p = 0.007) and on weekends (76% vs. 63%, p < 0.0001). Numerous differences between daytime and nighttime characteristics were observed for males, females, and adults, whereas most characteristics were similar for youth. The severity of injuries and proportion of fatalities were similar among daytime and nighttime crash victims. CONCLUSIONS: Nighttime crash victims, particularly adults, were characterized by more frequent risky behaviors like carrying passengers, roadway riding, alcohol use, and lack of helmets. Whereas the frequency of risky behaviors among youth was similar for daytime and nighttime crashes, these behaviors put children at potential risk for injury. Multi-factorial, targeted injury prevention strategies are needed, including improved vehicle design, education about the dangers of nighttime operation, and passage and enforcement of ATV safety laws. Particularly relevant to our study are laws that prohibit nighttime riding.

Firearm Exposure and Storage Practices in the Homes of Rural Adolescents.

INTRODUCTION: Rural areas have higher rates of firearm-related unintentional and suicide deaths. Having access to a firearm greatly increases suicide risk. Safe firearm storage can be a major factor in preventing these tragedies. In this study we evaluated firearm exposure and storage practices in rural adolescents' homes. METHODS: An anonymous survey was administered to a convenience sample of attendees at the 2019 Iowa FFA (formerly Future Farmers of America) Leadership Conference. We performed descriptive, bivariate and multivariable logistic regression analyses. RESULTS: A total of 1,382 adolescents participated; 51% were males and 49% were females. Respondents were 13-18 years old, and 53% lived on a farm, 18% in the country/not on a farm, and 29% in town. Almost all (96%) self-identified as White/Caucasian. In their homes, 84% reported having rifles/shotguns, 58% reported having handguns, and 56% reported having both rifles/shotguns and handguns. Males were significantly more likely than females to report having firearms in their home (P<0.001). The likelihood of having rifles/shotguns was greater if living on a farm (odds ratio (OR) 4.19, 95% confidence interval (CI), 2.99-5.88) or in the country/not a farm (OR 2.74, 95% CI, 1.78-4.24) compared to those in town. Similarly, the presence of handguns in the home was increased if living on a farm compared to in town (OR 1.70, 95% CI 1.32-2.18). Rifles/shotguns and handguns were stored unlocked and/or loaded at least some of the time in 62% and 58% of homes, respectively. Those who lived on farms compared to in towns were more likely to have rifles/shotguns (OR 1.83, 95% CI 1.35-2.46) and handguns (OR 1.58, 95% CI 1.10-2.27) stored unlocked. For homes with unlocked rifles/shotguns, 46% stored ammunition unlocked. For homes with unlocked handguns, 38% stored ammunition unlocked. Among those aware of firearm storage in their home, 82% (802/974) reported at least one firearm stored either unlocked and/or loaded at least some of the time. CONCLUSION: The vast majority of rural adolescents we surveyed live in homes with firearms, and a large proportion of those firearms are not stored safely. Widespread efforts are needed to educate rural families about the importance of proper firearm and ammunition storage.

Using a Resident-Led School Outreach Program to Improve Knowledge of All-Terrain Vehicle Safety.

BACKGROUND: During the past decade, all-terrain vehicle (ATV)-related injuries treated in US emergency departments decreased by 33%, down to approximately 100,000 injuries in 2016. In comparison, the number of children evaluated for ATV injuries in the Children's of Alabama emergency department more than doubled between 2006 and 2016, counter to the national trend. The American Academy of Pediatrics guidelines state that ATV operators should be at least 16 years old; however, children younger than 16 continue to represent almost one-third of all ATV-related injuries nationwide, and nearly all of the injuries to children in Alabama. METHODS: Using surveillance data from the Children's of Alabama hospital electronic medical record database, several Alabama counties near Birmingham were identified as having an increased number of children with ATV-related injuries in 2016. The Safety Tips for ATV Riders (STARs) program, developed in Iowa, was provided to middle school students in these counties by pediatric residents. Surveys were anonymously administered to children before and after the program and included information about demographics, knowledge of safe ATV practices, and the likelihood of using the education afterward. RESULTS: In total, 525 students participated in January 2019; their ages ranged from 11 to 15 years and the proportion of males and females was equivalent. More than 50% of the children reported riding ATVs in the last 12 months, and of these riders, 47% reported never wearing a helmet when riding. Initially, only 20% of the overall participants knew ATVs were not intended for passengers, 20% knew the recommended engine size for their age, and 57% knew that Alabama law prohibits riding on public roads. After education, this increased to 91%, 90%, and 89%, respectively. Before the STARs program, only 6% knew all three correct answers, whereas 80% answered all of the questions correctly on the postprogram survey. After the program, 34% reported they were very likely/likely to use this information in the future. CONCLUSIONS: The STARs program dramatically improved short-term ATV safety knowledge, and many participants reported they were likely to subsequently use the safe practices presented. School-based programs, such as STARs, may help increase ATV safety awareness and change behaviors in high-risk age groups. This training may be successfully provided by various motivated individuals, including medical residents.

Agricultural All-Terrain Vehicle Safety: Hazard Control Methods Using the Haddon Matrix.

All-terrain vehicle (ATV) crashes are one of the leading causes of death and injury in agriculture across the United States. Use of ATVs is highly prevalent in rural areas and has seen an increase in their application for a variety of agricultural work tasks. Empirical research on the use of these vehicles for agricultural tasks and associated injuries is limited, especially in the United States. Moreover, little is known about the risk factors associated with ATV-related injuries while doing farm work. A comprehensive review was conducted to evaluate the current injury burden of ATV use in agriculture, the need for future research, and possible solutions related to agricultural ATV safety. Potential injury prevention approaches are evaluated based on the hierarchy of control, including elimination or substitution (using side-by-side vehicles instead of ATVs or modifying ATV design), engineering control (operator protection devices), administrative authority (regulations and standards in the United States and around the world), training, and use of personal protective equipment. In addition, vehicle nomenclature, risk factors, and crash mechanisms are reviewed. Recommendations to decrease the likelihood of ATV crashes and injuries are provided.

Recreational off-highway vehicle crashes resulting in victims being treated at a regional trauma center: mechanisms and contributing factors.

BACKGROUND: Recreational off-highway vehicles (ROVs) have become increasingly popular in recent years; however, crash epidemiology is not well described. ROVs travel at least 30 mph, and unlike all-terrain vehicles, have a rollover protective structure (ROPS) and seat belts or a harness system for occupants. This study's objective was to evaluate the demographics, mechanisms, injuries, and associated risk factors of ROV crashes. METHODS: A retrospective chart review was performed for patients of all ages with ROV-related injuries presenting to a Level 1 trauma center from 2004 to 2017. Cases were identified by ICD-9/10 codes and narrative searches. Person- and crash-related variables were examined in relation to injury outcomes including body area injured, injury severity score, and disposition (e.g. hospitalization, intensive care unit admission). Descriptive, bivariate (chi-square, Fishers exact test), and linear regression analyses were performed. RESULTS: Seventy-two patients with ROV-related injuries were identified. The number of injured patients increased over the study period (p < 0.01). Patients were 49% youth < 16 years old, 63% males, and 99% Caucasian. Half of the injured (51%) were passengers, with a higher proportion of youth being passengers (70%) as compared to adults (35%) (p < 0.01). Nearly one-third (30%) of crash victims < 16 years old were ROV drivers. Twenty-nine percent of all crashes occurred on roadways. Almost 40% of injured adults crashed at night, while all youth were injured during the day (p < 0.01). The primary crash mechanism was a rollover (67%). Only one patient was documented as being helmeted, and approximately one-fourth (24%) sustained head injuries and/or loss of consciousness. Other documented injuries included those to the face (20%), chest (22%), abdomen (11%), extremities (58%), and skin (51%). Over 90% of narratives were consistent with victims being unrestrained. Nearly three-fourths (74%) of victims were hospitalized and 26% required ICU care, one-half (53%) of these being children. CONCLUSIONS: Although ROVs have ROPs, lack of helmet and safety belt use are reducing their benefit. Youth are a large proportion of those injured in ROV crashes, often while driving despite vehicle operation recommended only for those ≥16 years old. Increased public education is needed regarding proper safety measures while operating and riding ROVs.

Parental attitudes and family helmet use for all-terrain vehicles and bicycles.

BACKGROUND: Helmets prevent head trauma in both all-terrain vehicle (ATV) and bicycle crashes. This pilot study's objective was to compare family helmet use and participant attitudes regarding helmets for ATVs versus bicycles. METHODS: A convenience sampling of adults attending a 2017 university-sponsored health fair who had at least one child < 18 years living at home were surveyed. Demographics, frequency of helmet use, and information about factors influencing helmet use were collected. Descriptive (frequencies) and bivariate (Fisher's exact test) analyses were performed. Qualitative themes of written responses were also examined. RESULTS: Subjects (N = 98) were 26-57 years old (mean 40 years). Three-quarters (76%) were female. The percentage always wearing a helmet riding bicycles was 63% (subjects), 58% (spouses/partners), and 51% (children), compared to 11, 14 and 37% on ATVs, respectively. Moreover, the percentage never wearing a helmet while on an ATV was 68% for subjects, 71% for spouses, and 47% for children. Despite helmet use differences between bicycles and ATVs, the importance of children wearing a helmet on these vehicles was rated highly and equally important, 9.28 and 9.58 on a 1-10 scale, respectively. Higher proportions of subjects' oldest children wore a bike helmet 100% of the time if at least one parent always wore a helmet (81%), compared to children whose parents both wore helmets < 100% of the time or didn't ride (21%) (p < 0.0001). The proportion of children wearing ATV and bicycle helmets less than 100% of the time was significantly higher if parents reported barriers to effectively enforcing helmet use than if they did not (p = 0.04 and p = 0.004, respectively). Many reported a "strict no helmet, no bike/ATV riding rule" as being most effective in getting their children to always wear a helmet. CONCLUSIONS: This study is the first to explore family helmet use while riding bicycles vs ATVs. Although parent's belief in the importance of helmet use was high for both, helmet use was greater when riding bicycles. Further research is needed to better understand the social and environmental influences that shape parental helmet attitudes and practices in order to improve safety interventions for increasing pediatric helmet use.

Assessing the Emergent Public Health Concern of All-Terrain Vehicle Injuries in Rural and Agricultural Environments: Initial Review of Available National Datasets in the United States.

BACKGROUND: Injuries related to the operation of off-road vehicles (ORVs), including all-terrain vehicles (ATVs), continue to be a significant public health concern, especially in rural and agricultural environments. In the United States alone, ATVs have played a role in thousands of fatalities and millions of injuries in the recent decades. However, no known centralized federal surveillance system consistently captures these data. Traditional injury data sources include surveys, police reports, trauma registries, emergency department data, newspaper and online media reports, and state and federal agency databases. OBJECTIVE: The objectives of this study paper were to (1) identify published articles on ORV-related injuries and deaths that used large databases and determine the types of datasets that were used, (2) examine and describe several national US-based surveillance systems that capture ORV-related injuries and fatalities, and (3) promote and provide support for the establishment of a federally-funded agricultural injury surveillance system. METHODS: In this study, we examined several national United States-based injury datasets, including the web-based AgInjuryNews, the Fatality Analysis Reporting System, databases compiled by the US Consumer Product Safety Commission, and the National Fatality Review Case Reporting System. RESULTS: Our review found that these data sources cannot provide a complete picture of the incidents or the circumstantial details needed to effectively inform ORV injury prevention efforts. This is particularly true with regard to ORV-related injuries in agricultural production. CONCLUSIONS: We encourage the establishment of a federally funded national agricultural injury surveillance system. However, in lieu of this, use of multiple data sources will be necessary to provide a more complete picture of ORV- and other agriculture-related injuries and fatalities.

Adult moped-related injuries treated in U.S. emergency departments.

Objective: Few studies have investigated U.S. emergency department (ED) moped-related injuries. Our objective was to determine the characteristics of moped crashes among adult riders and to identify associations between key variables.Methods: Data were obtained from the National Electronic Injury Surveillance System (NEISS) for 2002-2014. Descriptive and comparative analyses of the identified cases were performed.Results: Based on a probability sample of 2,453 cases, an estimated 108,229 U.S. adult moped-related ED visits occurred during the study period. Injuries increased 2.7-fold over time. Summer months and weekdays were the most common crash times. Three-fourths of injured riders were male, two-thirds were ages 23-59 years, and 77% were Caucasian. Among cases documented, one-half were helmeted, and almost two-thirds of crashes occurred at ≤20 mph. The predominant mechanism was a non-collision crash (60%). Skin-related and musculoskeletal diagnoses were most common. Almost one-fifth of patients were admitted or transferred. Regression analyses showed that males were less likely than females to be in crashes with multiple riders, and more likely to have used alcohol/drugs and to be in a crash with another motor vehicle (MVC). Older riders (≥40 years) were more likely than those younger to have used alcohol/drugs and to suffer torso injuries, and less likely to be in an MVC. As compared to other crash mechanisms, MVCs were more likely to involve injuries to the head/neck/face and torso. The likelihood of being admitted/transferred was higher for males, with increasing age, and for collision-related crashes. The higher likelihood of being admitted/transferred was also characterized by alcohol/drug use, by lower limb and torso injuries, and almost 8 times more likely for riders with serious head injuries.Conclusions: Moped injuries increased in all adult age groups during the study period. However, there were significant differences in contributing factors, crash mechanism, and outcomes by sex, race, and age. These findings suggest the need for targeted injury prevention interventions.

Social workers' determination of when children's access or potential access to loaded firearms constitutes child neglect.

BACKGROUND: Pediatric firearm-related deaths and injuries are a serious societal problem. Our study's objective was to determine social workers' assessment of child neglect with respect to access or potential access to a loaded firearm. METHODS: Study invitations were delivered by e-mail to National Association of Social Workers members designating their practice as "Child/Family Welfare" (N = 4933) in October/November, 2015. Demographics, attitudes regarding child access prevention (CAP) laws, and the ages (4-14 years) at which social workers deemed several scenarios as child neglect were determined. Descriptive (frequencies) and bivariate (chi square) analyses were performed. RESULTS: 485 of 4933 social workers completed the survey (9.8%). Of these, most agreed or strongly agreed (≥92%) there should be laws in place requiring firearms to be stored so unwanted access cannot be obtained by a child, even up to 15 years of age. In a scenario where a child had potential access to a loaded firearm, but never gained access, the presence of a CAP law pertinent to the child in the scenario increased the likelihood respondents would find the situation child neglect for all ages (p < 0.0001 for each age comparison). Moreover, 10.3% felt they could not deem the situation child neglect without the presence of a CAP law, no matter the age of the child. In a scenario where a child gained access to a loaded firearm, the vast majority found this to be child neglect (82-99%, with the percentage varying by the age of the child involved), regardless of the presence or absence of a CAP law and/or an injury being sustained. In addition, when a CAP law was in place, social workers were more likely to find neglect if the child had sustained a firearm-related injury as well (p values ranged from 0.016-0.0081 for age comparisons). CONCLUSIONS: The vast majority of child/family welfare social workers surveyed found it to be child neglect when youth accessed or had potential access to a loaded, unsecured firearm. Results of the study provide support for the passage of universal CAP laws to help protect children equally across states and ensure the safe storage of firearms in homes.

Comparing the Efficacy of Methods for Immobilizing the Cervical Spine.

STUDY DESIGN: This was a prospective simulator study with 16 healthy male subjects. OBJECTIVE: The aim of this study was to compare the relative efficacy of immobilization systems in limiting involuntary movements of the cervical spine using a dynamic simulation model. SUMMARY OF BACKGROUND DATA: Relatively few studies have tested the efficacy of immobilization methods for limiting involuntary cervical movement, and only one of these studies used a dynamic simulation system to do so. METHODS: Immobilization configurations tested were cot alone, cot with cervical collar, long spine board (LSB) with cervical collar and head blocks, and vacuum mattress (VM) with cervical collar. A motion platform reproduced shocks and vibrations from ambulance and helicopter field rides, as well as more severe shocks and vibrations that might be encountered on rougher terrain and in inclement weather (designated as an "augmented" ride). Motion capture technology quantitated involuntary cervical rotation, flexion/extension, and lateral bend. The mean and 95% confidence interval of the mean were calculated for the root mean square of angular changes from the starting position and for the maximum range of motion. RESULTS: All configurations tested decreased cervical rotation and flexion/extension relative to the cot alone. However, the LSB and VM were significantly more effective in decreasing cervical rotation than the cervical collar, and the LSB decreased rotation more than the VM in augmented rides. The LSB and VM, but not the cervical collar, significantly limited cervical lateral bend relative to the cot alone. CONCLUSION: Under the study conditions, the LSB and the VM were more effective in limiting cervical movement than the cervical collar. Under some conditions, the LSB decreased repetitive and acute movements more than the VM. Further studies using simulation and other approaches will be essential for determining the safest, most effective configuration should providers choose to immobilize patients with suspected spinal injuries.

Pediatric and adolescent injury in all-terrain vehicles.

All-terrain vehicles (ATVs) remain a significant source of death and injury among youth. The purpose of this review is to provide an overview of the scope of the problem, the risk factors involved, crash-related outcomes and costs, and injury prevention strategies. There are currently more than 100 pediatric ATV-related fatalities each year and over 30,000 emergency department visits, with a potential annual cost for deaths and injuries approaching $1 billion. Major risk factors include lack of training, operating adult-size ATVs, riding as or carrying passengers, riding on the road, and not wearing a helmet. Extremity injuries are highly common, and the leading causes of death include brain injuries and multi-organ trauma. The latter increasingly involves being crushed by or pinned under the ATV. Reducing ATV-related deaths and injuries will require multiple strategies that integrate approaches from education, engineering, and evidence-based safety laws and their enforcement.

Comparing the Efficacy of Methods for Immobilizing the Thoracic-Lumbar Spine.

OBJECTIVE: The purpose of this study was to compare the relative efficacy of immobilization systems in limiting thoracic-lumbar movements. METHODS: A dynamic simulation system was used to reproduce transport-related shocks and vibration, and involuntary movements of the thoracic-lumbar region were measured using 3 immobilization configurations. RESULTS: The vacuum mattress and the long spine board were generally more effective than the cot alone in reducing thoracic-lumbar rotation and flexion/extension. However, the vacuum mattress reduced these thoracic-lumbar movements to a greater extent than the long spine board. In addition, the vacuum mattress significantly decreased thoracic-lumbar lateral movement relative to the cot alone under all simulated transport conditions. In contrast, the long spine board allowed greater lateral movement than the cot alone in a number of the simulated transport rides. CONCLUSION: Under the study conditions, the vacuum mattress was more effective for limiting involuntary movements of the thoracic-lumbar region than the long spine board. Moreover, the increased lateral bend observed with the long spine board under some conditions suggests it may be inadequate for immobilizing this anatomic region as presently designed. Should emergency medical service providers choose to immobilize patients with suspected injuries of the thoracic-lumbar spine, study results support the use of the vacuum mattress.

Child abuse and neglect experts' determination of when a child being left home alone constitutes child neglect.

BACKGROUND: Only 14 states have laws or guidelines regarding the minimum age a child may be left home alone. These ages range from 6 to 14 years. Our objective was to identify factors that influence child neglect determination by experts with regards to parents leaving children home alone. METHODS: American Academy of Pediatrics Section on Child Abuse and Neglect members (N = 523) were surveyed from July-August, 2015. Respondents were asked whether scenarios involving a child of varying age knowingly left home alone for 4 h were neglect in the presence or absence of injury to the child and the legality of the situation. Comparisons were performed using the chi-square test. RESULTS: One hundred ninety-three members responded (36.9%). In the scenario where there were no relevant laws and the child was uninjured, nearly 100% of the child experts determined this as being child neglect when the child was 6 years old. For 8, 10, 12, and 14 year olds, this was 88, 48, 4, and 1%, respectively. However, a significantly higher percentage of experts considered it child neglect for most ages when there was a law making the scenario illegal as compared when there was no law, and when the child was injured versus when they were not. The only demographic variable that showed a difference in child neglect determination was that females were more likely to consider higher aged children as having been neglected when there were no laws but the child was injured. The vast majority of experts (85%) stated that leaving a child home alone for 4 h should be illegal if the child is < 9 years old, and nearly one-half (44%) said it should be illegal for children < 11 years old. CONCLUSIONS: A number of factors affect how experts view children being left home alone as potential child neglect. Our data suggests that such cases may be evaluated differently due to variations in state laws, even though the risk to the child is the same. These results call for child safety law reform to provide greater uniformity in the evaluation of potential child neglect cases and better protect the safety of children.
