Age-based risk factors for pediatric ATV-related fatalities

Limitations in the field of vision of young operators of utility all-terrain vehicles

PROBLEM

All-Terrain Vehicles (ATVs) cause a distressing number of fatalities and injuries among farm youth in the United States. The number of severe injuries caused by ATV crashes on farms, which stood at 25 children in 2019, is expected to rise due to increased ATV sales during the COVID-19 pandemic. Existing research into children's injuries has explored physical capabilities like anthropometry, strength, and visual acuity. Yet, studies assessing youths' physical ability to operate ATVs remain limited. This study tests the hypothesis that diminished vision field in young ATV operators raises crash risks.

METHODS

This study used SAMMIECAD digital human modeling system to simulate and compare the field of vision of youth and adult ATV operators. The simulations incorporated 3-D mockups of ATVs, humans, sprayer tanks, windshields, and obstacles. Ten utility ATVs and children of both genders across nine ages (8-16) and three height percentiles (5th, 50th, 95th) were evaluated.

RESULTS

Simulations showed that young ATV operators generally have a more restricted field of vision than adults, particularly those aged 6-11 years.

DISCUSSION

Visual limitations hinder riders' ability to see ATV controls, potentially leading to vehicle control loss. Moreover, they impair environmental perception during riding, compromising youths' ATV operation abilities and increasing crash risks.

PRACTICAL APPLICATIONS

These findings offer crucial data in support of modifying ATV safety guidelines. Additionally, they can guide youth occupational health professionals in preventing ATV-related incidents in agricultural settings.

Injury Pattern and Outcomes Following All-Terrain Vehicle Accidents in Kentucky Children: A Retrospective Study

PURPOSE

All-terrain vehicles (ATVs) pose a significant risk for morbidity and mortality amongst children. We hypothesize that current vague legislation regarding helmet use impacts injury patterns and outcomes in pediatric ATV accidents.

METHODS

The institutional trauma registry was queried for pediatric patients involved in ATV accidents from 2006 to 2019. Patient demographics and helmet wearing status were identified in addition to patient outcomes, such as injury pattern, injury severity score, mortality, length of stay, and discharge disposition. These elements were analyzed for statistical significance.

RESULTS

720 patients presented during the study period, which were predominantly male (71%, n = 511) and less than 16 years old (76%, n = 543). Most patients were not wearing a helmet (82%, n = 589) at time of injury. Notably, there were 7 fatalities. A lack of helmet use is positively associated with head injury (42% vs 23%, P < .01), intracranial hemorrhage (15% vs 7%, P = .03), and associated with lower Glasgow Coma Scale (13.9 vs 14.4, P < .01). Children 16 years and older were least likely to wear a helmet and most likely to incur injuries. Patients over 16 years had longer lengths of stay, higher mortality, and higher need for rehabilitation.

CONCLUSION

Not wearing a helmet is directly correlated with injury severity and concerning rates of head injury. Children 16 years and older are at greatest risk for injury, but younger children are still at risk. Stricter state laws regarding helmet use are necessary to reduce pediatric ATV-related injury burden.

Forces required to operate controls on agricultural all-terrain vehicles: implications for youth

All-terrain vehicle (ATV) crashes are among the leading causes of injury and death among youth in the agriculture industry. It is hypothesised that youth are involved in ATV-related incidents because they cannot effectively activate the vehicle's controls. This study evaluated potential discrepancies between the required activation forces of the controls of fifty-four utility ATVs and the strength of male-and-female youth of varying ages (6-20 years old) and strength percentiles (5th, 50th, and 95th). The activation forces of the ATVs' controls were measured experimentally, while the youth's corresponding strength was retrieved from the literature. The results of this study demonstrated a physical mismatch between the forces required to operate ATV controls and youth's strength. Turning the handlebar, pressing the footbrake, and pushing the ATV off are the most difficult tasks for ATV operation. These discrepancies compromise the youth's ability to ride ATVs, increasing their risk of crashes. Practitioner summary: Previous studies indicate that some youth engage in ATV incidents because they cannot activate the vehicle's controls. We measured the forces required to operate eight ATV controls and compared them with the youth's corresponding strength. Our results demonstrated physical mismatches between the forces required to operate ATV controls and the youth's strength.

Changes in pediatric injuries sustained while engaged in activities where helmet usage is recommended during the COVID-19 pandemic

BACKGROUND

Unintentional injuries, including traumatic brain injuries (TBI), are the leading cause of pediatric morbidity and mortality in the USA. Helmet usage can reduce TBI incidence and severity; however, the epidemiology of pediatric TBI and helmet use is ever evolving. With lifestyle changes potentially accelerated by the pandemic, we predicted a decrease in helmet utilization with an associated increase in TBI during the pandemic compared to the pre-pandemic period.

RESULTS

There were 1093 patients that presented with AWHUR injuries from 2018 to 2020 with an annual increase from 263 patients in 2018 up to 492 in 2020. The most frequently implicated mechanisms included bicycles (35.9%), ATVs (20.3%), skateboards (11.6%), scooters (8.3%), and dirt bikes (7.4%). Unhelmeted patients increased from 111 (58.7%) in 2018 to 258 (64.8%) in 2020. There was not a significant difference in the proportion of injuries that were unhelmeted from 38.9% in 2018-2019 to 35.2% in 2020 (p = 0.30), as well as the proportion of head injuries from 2018 to 2019 (24.3%) to 2020 (29.3%) (p = 0.07). A significant increase was seen in neurosurgical consultation from 17 (6.5%) in 2018 to 87 (17.7%) in 2020 (p = 0.02). Notably, there was an increase in the percentage of publicly insured patients presenting with injuries from AWHUR during 2020 (p < 0.001); this group also had suboptimal helmet usage.

CONCLUSION

This study found an increase in patients presenting with injuries sustained while engaged in AWHUR in relation to the COVID-19 pandemic. Concerningly, there was a trend toward decreased helmet utilization and increased injury severity markers. Further analysis is needed into the communities impacted the most by AWHUR injuries.

Ability of youth operators to reach agricultural all-terrain vehicles controls

PROBLEM

Utility All-Terrain Vehicles (ATVs) are one major cause of youth injuries and fatalities on farms. Utility ATVs have heavy weights and fast speeds that require complex maneuvering. Youth's physical capabilities may not be sufficient to perform those complex maneuvers correctly. Therefore, it is hypothesized that most youth engage in ATV-related incidents because they ride vehicles unfit for them. There is a need to assess ATV-youth fit based on youth anthropometry.

METHOD

This study focused on evaluating potential inconsistencies between the operational requirements of utility ATVs and the anthropometric measures of youth through virtual simulations. Virtual simulations were performed to assess 11 youth-ATV fit guidelines proposed by several ATV safety advocacy organizations (National 4-H council, CPSC, IPCH, and FReSH). In total, 17 utility ATVs along with male-and-female-youth of nine ages (8 to 16 years old) and three height percentiles (5th, 50th, and 95th) were evaluated.

RESULTS

The results demonstrated a physical mismatch between ATVs' operational requirements and youth's anthropometry. For example, male-youth aged 16 of the 95th height percentile failed to pass at least 1 out of the 11 fit guidelines for 35 % of all vehicles evaluated. The results were even more concerning for females. Female youth 10 years old and younger (from all height percentiles) failed to pass at least one fit guideline for all ATVs evaluated.

DISCUSSION

Youth are not recommended to ride utility ATVs.

PRACTICAL APPLICATIONS

This study provides quantitative and systematic evidence to modify current ATV safety guidelines. Furthermore, youth occupational health professionals could use the present findings to prevent ATV-related incidents in agricultural settings.

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.

Factors Affecting Neurological Presentation and Severity in Pediatric Off-Highway Vehicle Accidents in Texas

OBJECTIVES

The purpose was to evaluate the characteristics of off-highway vehicle (OHV) crashes correlated with neurological injury and accident severity in the pediatric population in El Paso, Texas.

METHODS

A retrospective review of 213 patients who were victims of an OHV crash attended at a regional Level I trauma center from 2012 to 2020 was performed. OHVs were defined as vehicles designated for use outside public roads. Neurological outcomes included any traumatic brain injury (TBI) or a brain hemorrhage/hematoma. Severe injury was defined as a Glasgow Coma Scale less than 8, a length of stay longer than 7 days, a Pediatric Trauma Score lower than 8, and requiring pediatric intensive care unit admission. Bivariate and multivariate analyses by logistic regression models were conducted to determine the factors related to the neurological outcomes and accident severity.

RESULTS

Of 213 OHV crash patients, 104 (48.8%) had TBI and 22 (10.3%) had brain hemorrhages or hematomas. Risk analyses demonstrated that children younger than age 6 years and occupants of recreational OHVs have a significantly higher risk of severe injuries. Off-highway motorcycles and all-terrain vehicles were risk factors for TBI, whereas helmets were a protective factor.

CONCLUSIONS

OHVs are associated with both TBIs and severe injuries. Stricter laws requiring helmets and forbidding children younger than 6 to ride are required, as modifying these factors could reduce the incidence of OHV crashes and their complications.

Impact of All-Terrain Vehicle Accidents on Pediatric Patient Outcomes at an Appalachian Children’s Hospital

Introduction

The use of all-terrain vehicles (ATVs) has become increasingly popular as an outdoor recreational activity among people living in the United States, particularly in areas such as the southeast. There are significant risks involved with riding ATVs, especially in the pediatric population, due to lack of training and experience. The purpose of this study was to evaluate the outcomes of pediatric patients involved in ATV-associated accidents.

Methods

This study is a retrospective review of 98 pediatric patients ages 15 years and younger involved in ATV accidents who were admitted to a pediatric hospital between January 2015 and December 2020. Outcomes, including types of injuries sustained, length of hospital stay, length of ICU stay, and injury severity score (ISS) were analyzed between age groups (0-5, 6-10, and 11-15).

Results

The mean hospital stay across all age groups was 1.7 ± 1.9 days, mean ICU stay was 3.8 ± 4.0 days, and mean injury severity score (ISS) was 5.9 ±4.8. The 11-15-year-old age group had a significantly longer hospital stay and higher ISS scores compared to both of the younger age groups (0-5 and 6-10 years old). There was no difference in ICU days between the age groups. Orthopedic injuries were the most common type of injury, occurring in 55% of all patients, followed by head injuries in 29% of patients, and spinal fractures in 2% of patients. The most common orthopedic fracture in the 11-15-year-old group was tibia/fibula, while humerus fractures were the most common type of fracture in the 0-5 and 6-10 year age groups. Orthopedic procedures were required in 35% of all included patients. There was no statistically significant difference in types of injuries and types of fractures sustained between each group. Chest injuries, including pneumothorax, lung contusions, and rib fractures, occurred most often in the older age group 11-15 years (n=65). Those who experienced chest injuries had a higher ISS, although it was not statistically significant (p=0.06) compared to those who did not have chest injuries. There was no difference in hospital or ICU length of stay in patients with chest injuries.

Conclusions

The results of this study demonstrate the outcomes of pediatric patients admitted for ATV accidents at a rural Appalachian pediatric hospital and provide an overview of the most common injuries involved in this trauma mechanism. Pediatric patients aged 11-15 years of age involved in ATV accidents are at risk for longer hospital length of stay and higher ISS compared to younger age groups. Additionally, patients ages 11-15 were more susceptible to chest injuries following ATV accidents. The results of this study will be used to develop a standardized trauma protocol for the management of this specific trauma mechanism in the pediatric population based on common injury patterns among each age group.

Risk factors associated with quadbike crashes: a systematic review

Background

Quadbikes or all-terrain vehicles are known for their propensity for crashes resulting in injury, disability, and death. The control of these needless losses resulting from quadbike crashes has become an essential contributor to sustainable development goals. Understanding the risk factors for such injuries is essential for developing preventive policies and strategies. The aim of this review was to identify the risk factors associated with quadbike crashes at multiple levels through a systematic review of a wide range of study designs.

Methods

The study incorporated a mixed-method systematic review approach and followed the PRISMA 2020 guidelines for reporting systematic reviews, including a peer reviewed  protocol. This systematic review included observational studies investigating the risk factors associated with quadbike crashes, injuries, or deaths. Seven electronic databases were searched from inception to October 2021. Studies were screened and extracted by three researchers. Quality appraisal was conducted using the Mixed Methods Appraisal Tool (MMAT). Due to extensive heterogeneity, meta-analysis was not conducted. All the risk factors have been presented in a narrative synthesis for discussion following the guidelines for Synthesis without Meta-analysis (SWiM).

Results

Thirty-nine studies combining an aggregate of 65,170 participants were included in this systematic review. The results indicate that modifiable risk factors, such as the increasing age of driving initiation, reducing substance use, and the use of organized riding parks, could reduce quadbike injuries. Riding practices such as avoiding passengers, avoiding nighttime riding, and using helmets could significantly reduce crashes and injuries among riders. Vehicle modifications such as increasing the wheelbase and limiting engine displacement could also help reduce crash incidence. Traditional interventional methods, such as legislation and training, had a weak influence on reducing quadbike injuries.

Conclusion

Multiple risk factors are associated with quadbike injuries, with most of them modifiable. Strengthening policies and awareness to minimize risk factors would help in reducing accidents associated with quadbikes.

All-terrain vehicle (ATV)-related injuries among different age groups: insights from a 9-year observational study

PURPOSE

To describe the epidemiology, patterns, seasonality and outcome of all-terrain vehicle-related injuries (ATVRIs) among different age groups in Qatar.

METHODS

A retrospective analysis of all patients hospitalized with ATVRI from 2010 to 2018 was conducted. Data were analyzed by age, gender, seasonality, and Injury severity Score  (ISS). Chi-square, Student t and ANOVA tests were used for analysis. Multivariate regression analysis was performed to find out predictors of head injury and severe injury among ATV users.

RESULTS

Out of 15,000 trauma admissions, 521 had ATVRI (4%) with a mean age of 23.3 ± 12.3. The male-to-female ratio was 4:1 and the pediatric population represented 40%. The compliance with helmet use was 3.6%. The most injured regions were chest (29.8%), upper extremities (28.8%) and the head (25.9%). The mean ISS was 10.6 ± 7.7. Fracture fixation was the most operative intervention. Among hospitalized patients, 7.7% were transferred to rehabilitation . ATVRIs occurred more frequently between October and April and a large proportion (57.8%) occurred during weekends. The overall ATV-related hospital mortality rate was 2.1%. Young and older ATV users were more likely to suffer spine injuries than the pediatric population (p = 0.001). The mean ISS was greater in the older groups (p = 0.03). There were no statistically significant differences regarding the use of protective devices, mortality, or length of hospital stay between the different age groups. On multivariate analysis, young age and ISS were predictors of head injury among ATV users after adjusting for gender and helmet use.

CONCLUSION

This is a nationwide study looking at all age groups who sustained ATVRI in Qatar. ATVRIs were observed in all age groups following leisure and recreational use. It follows a seasonal pattern with poor protective measures compliance. There is a need to reinforce helmet use and raise public awareness.

Socioeconomic factors associated with helmet use in pediatric ATV and dirt bike trauma

Objectives

Recreational off-road vehicle crashes can produce severe injury and death among children, often from head trauma sustained while riding unhelmeted. Although required for competition, recreational riders commonly forego helmets. This study aimed to identify socioeconomic factors associated with unhelmeted injuries among children riding all-terrain vehicles (ATVs) and dirt bikes recreationally, thus informing injury prevention efforts.

Methods

A retrospective review was completed of patients younger than 18 years who presented after recreational ATV or dirt bike crash to a single American College of Surgeons-verified level 1 pediatric trauma center (2010-2019). Demographic, injury, and outcome data were collected. US Census data regarding median and per capita income, poverty prevalence, and scholastic graduation rates were recorded for each patient's home county. Relationships between helmet use at the time of injury, demographics, and socioeconomic variables were examined.

Results

The cohort comprised 680 injured recreational ATV (n=510; 75%) and dirt bike (170; 25%) riders. Unhelmeted riders (n=450) were significantly older (median age 13 vs 11 years; p=0.008) and more often rode ATVs (n=399). Significantly greater percentages of females (77.9%; p<0.001) and passengers (89.5%; p<0.001) were unhelmeted at the time of injury. Residents of counties with lower median and per capita income, higher poverty prevalence, and lower high school and college graduation rates were significantly more likely to be unhelmeted at the time of their crash (p=0.003). In multivariable analysis, unhelmeted injuries were independently associated with ATV use (OR=6.757; p<0.0001), passenger status (OR=6.457; p<0.0001), and older age (OR=1.219; p<0.0001).

Conclusion

In children, ATV use, passenger status, and older age associated independently with unhelmeted riding in recreational vehicle crash. Residence in a county with both lower median income and scholastic graduation rates associated with unhelmeted crashes, and lower median income significantly predicted unhelmeted crashes. This study revealed socioeconomic factors that identify communities with greatest need for injury prevention initiatives.

Golf cart injuries in children: the experience of trauma centers in a single state in the USA

Golf carts remain a source of morbidity in children. We aimed to establish the incidence and injury characteristics of pediatric patients injured due to golf cart usage over an 11-year period. This is a retrospective study using a single state trauma database of patients ages 0-17 years admitted to a trauma center and who sustained injures while a golf cart was in use. Thirteen Pediatric and Adult Trauma Centers within the state of Pennsylvania were evaluated from 1 January 2004 to 31 December 2014. The inclusion criteria were met by 108 patients. The mean annual incidence of injuries was 0.35/100 000. The median age of patients was 11 years. The median hospital length of stay and injury severity score were 2 days and 9.5, respectively. The majority of the patients (75.9%) sustained at least one bone fracture. Skull fractures were more prevalent (43.5%), whereas extremity fractures were sustained by 26.9% of patients. Intracranial hemorrhages were sustained by 29.6% of patients. Ejections and rollovers accounted for 58.3% and 31.4% of patient injuries, respectively. The concussion rate was 26.9%. Neither age group nor sex was associated with a difference in fractures, intracranial hemorrhage or concussions. Golf cart injuries in pediatric patients commonly stem from ejections and rollover mechanisms resulting in skull fractures, extremity fractures, intracranial hemorrhages and concussions. The overall incidence of injury was 0.35 cases per 100 000. Further efforts are needed to increase awareness of these injuries and modify regulations regarding the use of golf carts in the pediatric population.

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.

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.

Material deprivation and rates of all-terrain vehicle- and snowmobile-related injuries in Ontario from 2003 to 2018: a population-based study

OBJECTIVES

Socio-economic status (SES) is a well-established predictor of health outcomes; however, there is a dearth of evidence on the relationship between SES and off-road vehicle (ORV) injuries. In Ontario, all-terrain vehicles (ATVs) and snowmobiles present a serious risk for preventable injury. This study assessed the association between area-level material deprivation and the risk of ATV- and snowmobile-related injuries in Ontario, as well as the impact of sex and age.

METHODS

A population-based, repeat cross-sectional study was conducted using administrative data of ATV- and snowmobile-related emergency room visits from 2003 to 2018. Material deprivation was measured using the Ontario Marginalization Index, which assigned a score and quintile of deprivation to each dissemination area in Ontario. Age-standardized incidence rates and relative index of inequality values were calculated, stratified by quintile of deprivation, sex, age group, vehicle type, and health region.

RESULTS

We found a significant, positive relationship between ORV-related injuries and quintile of material deprivation (RII = 1.28, 95% CI: 1.01-1.63). Rates of ATV- and snowmobile-related injuries remained stable over time. Across all age groups, sex, and rural categories, we found an inverse u-shaped relationship between rates of injuries and quintile material deprivation. Males, individuals living in rural areas, and adolescents and young adults experienced the highest rates of injuries.

CONCLUSION

Despite the positive relationship between ORV-related injuries and quintiles of deprivation, the inverse u-shaped relationship suggests that this increased risk of injury is likely related to exposure to ORVs. These results contribute to an understanding of the prevalence of the injury problem at a local level in Ontario. Stable rates of injury over time suggest that current public health programs are not sufficient in reducing these injuries, and further research should determine which factors amenable to intervention are contributing to increased risk of injury.

Strategies in liver Trauma

The management of pediatric liver trauma has evolved significantly over the last few decades. While surgical intervention was frequently and mostly unsuccessfully practiced during the first half of the last century, the 1960s were witness to the birth and gradual acceptance of non-operative management of these injuries. In 2000, the American Pediatric Surgical Association (APSA) Trauma Committee disseminated evidenced-based guidelines to help guide the non-operative management of pediatric blunt solid organ injury. The guidelines significantly contributed to conformity in the management of these patients. Since then, a number of well-designed studies have questioned the strict categorization of these injuries and have led to a renewed reliance on clinical signs of the patient's hemodynamic status. In 2019, APSA introduced an updated set of guidelines emphasizing the use of physiologic status rather than radiologic grade as a driver of clinical decision making for these injuries. This review will focus on liver injuries, in particular blunt injury, as this mechanism is by far the most commonly seen in children. Procedures required when non-operative management fails will be detailed, including surgery, angioembolization, and less commonly employed interventions. Finally, the updated inpatient and post-discharge aspects of care will be reviewed, including hemoglobin monitoring, bedrest, length of hospital stay, and activity restriction.

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.

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.

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.

Pediatric hospitalizations and in-patient mortality from all-terrain vehicle crashes, 2006–2016

Purpose

To evaluate trends in national frequency of hospitalizations and in-patient mortality in the United States for children injured in all-terrain vehicle crashes during the past decade.

Methods

Retrospective review of the 2006, 2009, 2012, and 2016 Kids' Inpatient Databases to identify hospitalizations of patients <19 years of age for all-terrain vehicle-related injuries. External-cause-of-injury codes were used to identify patients hospitalized for injuries sustained in all-terrain vehicle crashes. Odds ratios for in-patient mortality were calculated by logistic regression incorporating multiple individual demographic and hospital variables.

Results

Estimated all-terrain vehicle-related hospitalizations ranged from 3666 in 2006 (5.2/100,000 persons <19 years of age) to 2558 in 2012 (3.3/100,000). Crude in-patient mortality was low, and varied slightly from year to year (range, 0.55–1.04%). Patients hospitalized for all-terrain vehicle-related injuries were 76.8–78.4% White and 72.1–77.2% male. Totally 61.0–64.3% had private insurance, 35.3–39.3% were from rural areas, 37.4–38.3% were in the 10–14-year age group, and patients from the West region accounted for 40.4–43.6% of patients. There were no risk factors identified as being consistently associated with mortality in this cohort. Average total charges increased from $26,996 to $67,370 over the course of the study ( p < 0.001).

Conclusions

Hospitalizations for all-terrain vehicle-related injuries in children have fallen in the past decade although the reasons for this change are unknown. In-patient mortality rates have stayed relatively constant and while no factors were predictive of in-patient mortality, demographic data may provide an opportunity for targeted interventions to further reduce injuries and associated hospital costs.

The Effect of All-Terrain Vehicle Crash Location on Emergency Medical Services Time Intervals

Over 100,000 all-terrain vehicle (ATV)-related injuries are evaluated in U.S. emergency departments each year. In this study, we analyzed the time intervals for emergency medical services (EMS) providers responding to ATV crashes in different location types. Data from the Iowa State Trauma Registry and a statewide ATV crash/injury database was matched with Iowa EMS Registry records from 2004–2014. Ground ambulance responses to 270 ATV crashes were identified, and response characteristics and time intervals were analyzed. Off-road crashes had a longer median patient access interval (p < 0.001) and total on scene interval (p = 0.002) than roadway crashes. Crashes in remote locations had a longer median patient access interval (p < 0.001) and total on scene interval (p < 0.001), but also a longer median on scene with patient interval (p = 0.004) than crashes in accessible locations. Fifteen percent of remote patient access times were >6 min as compared to 3% of accessible crashes (p = 0.0004). There were no differences in en route to scene or en route to hospital time. Comparisons by location type showed no differences in injury severity score or number of total procedures performed. We concluded that responding EMS providers had an increased length of time to get to the patient after arriving on scene for off-road and remote ATV crashes relative to roadway and accessible location crashes, respectively.

Risk Factors and Outcomes From All-Terrain Vehicle Injuries Compared With Motor Vehicle Collisions in Children

We compared risk factors and outcomes of children injured from all-terrain vehicle (ATV) injuries to those injured from motor vehicle collisions (MVC). We reviewed records of patients ≤18 years of age admitted to a trauma center with ATV- or MVC-related injuries between January 1, 2000, and December 31, 2015. Demographics were compared using logistic regression. Rates of injuries were compared using χ² tests. Of 6293 patients, 1140 (18%) ATV and 5153 (82%) MVC events were identified. In multivariable analysis (adjusted odds ratio [aOR], 95% confidence interval [CI]), patients with ATV-related injuries occurred more at older age (≥12 years; aOR = 4.29, 95% CI = 3.20-5.77), in rural counties (aOR = 3.72, 95% CI = 2.62-5.28), in regions with lower median household income (aOR = 1.37, 95% CI = 1.03-1.83), and in the spring (aOR = 2.44, 95% CI = 1.87-3.18), and summer (aOR = 2.50, 95% CI = 1.93-3.25) compared with winter. ATV-related injuries occurred less frequently among females (aOR = 0.76, 95% CI = 0.65-0.89). Upper extremity injuries were associated with ATV-related injuries (P ≤ .001). Findings may facilitate identification of at-risk groups for targeted interventions.

Enforcement of Off-Road Vehicle Laws in Iowa

Safety laws are among the most successful means of reducing injuries, but their effectiveness is strongly influenced by the level of enforcement. To characterize enforcement of off-road vehicle (ORV) laws statewide, analyses of citations were performed using Iowa Court Information System data. From 2005–2015, 5173 individuals were charged with 5643 citations issued. Citations averaged <5/county/year, decreased dramatically over time, and varied by county when normalized to registered all-terrain vehicles (ATVs). Over 90% of operators cited were male and Caucasian. One-fifth were <18 years old. The top five violations were: operation on a highway/snowmobile trail (51%), registration/identification number not documented/displayed (19%), prohibited use in a park/preserve (5.5%), and operation with more persons than the vehicle is designed to carry (4.4%). The Department of Natural Resources issued the highest percentage of citations, followed in decreasing order by Sheriff, Police, State Patrol, and Conservation officers. Significant differences were identified when citations were compared by sex, age, race, enforcement agency, disposition (guilty vs. not guilty), and when comparing counties with or without an ORV park. These characteristics suggest limited and variable enforcement of laws statewide that may reduce their potential to prevent deaths and injuries, and that improved strategies to support ORV law enforcement are needed.

All-terrain vehicle use related fracture rates, patterns, and associations from 2002 to 2015 in the USA

BACKGROUND

Since their introduction to USA markets in the late 20^th century, all-terrain vehicles (ATVs) have been a significant source of trauma. Many paediatric studies have demonstrated the disproportionate rate in which minors are affected by ATV-related trauma, but no studies have been performed on a large sample size spanning all age and geographic ranges. This study is the first to analyze ATV-related fracture rates, patterns, and associated risks across all ages nationwide.

METHODS & STATISTICAL ANALYSIS

The National Electronic Injury Surveillance System (NEISS) was queried for ATV-related trauma for the years 2002-2015. The data were analyzed by age, sex, race, alcohol usage, helmet usage, type of injury, fracture location, and disposition from the emergency department (ED). Continuous data were analyzed using the t-test (2 groups) or ANOVA (≥3 groups). Discrete data were analyzed using χ² tests. SUDAAN 10™ software was used to account for the stratified and weighted nature of the data. Significance was set at p < 0.05.

RESULTS

There were an estimated 1,862,342 ED visits for ATV-related injuries from 2002 to 2015; 482,501 (25.9%) sustained fractures with a mean age of 27.5 years. Among those with fractures, 75.7% were male, 28.5% resulted in hospital admission, 43.9% occurred at home, and 57.5% were unhelmeted. Anatomically, 51.8% involved the upper extremity, 23.6% involved the lower extremity, 6.4% involved the spine, 8.5% involved the skull/face, and 9.7% involved the ribs/sternum. Alcohol use was most frequently associated with skull (13.2%) and cervical spine (13.0%) fractures. Patients with skull or facial fractures were unhelmeted 88% of the time, and 87% of skull fractures were associated with brain injury. ATV-related fractures peaked in 2007 at 44,283 and trended downward through 2014.

CONCLUSION

This study is the first of its kind to analyze ATV-related trauma over all age groups throughout the entire USA. It can serve as a reference for clinical decision-making and future studies. It also reinforces the need for ATV regulation advocacy, specifically helmet use.

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.

Trends in All-terrain Vehicle Injuries From 2000 to 2015 and the Effect of Targeted Public Safety Campaigns

INTRODUCTION

All-terrain vehicles (ATVs) represent a notable portion of orthopaedic injuries presenting to emergency departments (EDs) in the United States. Public awareness campaigns have targeted these injuries, and this study sought to examine the effect of the 2007 American Academy of Orthopaedic Surgeons public safety campaign on ATV use.

METHODS

The United States Consumer Product Safety Commission National Electronic Injury Surveillance System (NEISS) was used to obtain national estimates of ATV and dirt bike injuries for the years 2000 to 2015. ED visits resulting from ATV injuries and dirt bike injuries were identified using NEISS product codes (ie, 3285-3287, 3296, and 5036). Patient demographics, injury-related data, and total annual case numbers were estimated. Chi-square tests and logistic regression were used for comparative analyses as appropriate. All statistical analyses were performed using SAS statistical software v.9.4 (SAS Institute). Statistical significance was set at P < 0.05 a priori.

RESULTS

Beginning in 2000, the incidence of ATV injuries consistently increased over time and peaked in 2007 (54.1/100,000 people). Since 2007, the incidence of ATV injuries has consistently decreased (33.7/100,000 people in 2015). The frequency of ATV injuries differed significantly (P < 0.001) by age group, with children aged 14 to 17 years experiencing the highest incidence of ATV injury (2.8× national average). ATV injuries were also more common in males (2.7× national average; P < 0.001). The most common injuries were contusions and abrasions (25.3%), fractures (24.5%), and lacerations (11.4%). The decreased rate of ATV injury beginning in 2007 did not differ significantly (P = 0.81) from a comparative decrease in dirt bike-related injuries.

DISCUSSION

This study provides the most current data on ATV injuries presenting to EDs in the United States. The rate of ATV-related injuries has steadily decreased since 2007, which corresponds to the American Academy of Orthopaedic Surgeons public awareness campaign. However, the reasons for this decrease are likely multifactorial. Children aged 14 to 17 years are at high risk of ATV-related injuries, with orthopaedic injuries accounting for a notable proportion.

A Cross-Sectional Study of Emergency Department Visits by Children After All-Terrain Vehicle Crashes, Motor Vehicle Crashes, and Sports Activities

OBJECTIVES

All-terrain vehicle (ATV) crashes have been responsible for significant injuries among children, despite public education efforts. Our study examined pediatric ATV injury patterns in US emergency departments (EDs) compared with injuries after motor vehicle crash (MVC) and sports activities.

METHODS

We studied 2006 to 2011 data from the Nationwide Emergency Department Sample. Children younger than 18 years and involved in ATV crashes, MVC, or sports activities were included. The primary outcome analyzed was a constructed binary measure identifying severe trauma, defined as injury severity score greater than 15. Logistic regression models were fit to determine the association between mechanism of injury and severe trauma.

RESULTS

A total of 6,004,953 ED visits were identified. Of these, ATV crashes accounted for 3.4%, MVC accounted for 44.7%, and sports activities accounted for 51.9%. Emergency department visits after ATV crashes were more likely to result in admission (8%) and incur higher median charges ($1263) compared with visits after sports activities (1%, $1013). Visits after sports activities were 90% less likely to result in severe trauma when compared with ATV crash visits. Emergency department visits after ATV crashes result in severe injuries similar to those sustained in MVC (odds ratio, 1.03; P = 0.626).

CONCLUSIONS

Pediatric ED visits after ATV crashes result in significant injuries and charges. Public health interventions such as education, legislation, and engineering are needed to reduce injuries among children and the subsequent ED visits for care. The impact of proven interventions may be greatest for children living in rural areas and among older children, 10 to 17 years old.

Do Professional Society Advocacy Campaigns Have an Impact on Pediatric Orthopaedic Injuries?

PURPOSE

The American Academy of Orthopaedic Surgeons (AAOS) and the American Academy of Pediatrics (AAP) both advocate for childhood injury prevention by publishing recommendations to orthopaedic surgeons, pediatricians, and the public. Popular topics of advocacy campaigns have included trampolines, all-terrain vehicles (ATVs), and lawnmowers. The purpose of this study was to investigate the temporal relationship between AAOS/AAP advocacy and pediatric orthopaedic injury rates, using these topics as examples. We hypothesized that pediatric orthopaedic injury rates decline in years, following related AAOS/AAP recommendations.

METHODS

A retrospective review of fractures associated with trampolines, lawnmowers, and ATVs among patients aged 2 to 18 years from 1991 to 2014 was performed using the National Electronic Injury Surveillance System (NEISS). Fracture rates and percent changes year-to-year were calculated. A timeline of AAOS and AAP advocacy statements published on the products was created.

RESULTS

Trampoline-related fractures rose 14% yearly from 1991 to 1999, reached a plateau from 1999 to 2003, corresponding with a 1999 AAP statement. Injury rates dropped 4.3% from 2006 to 2010 after 2005 and 2006 statements, and reached another plateau thereafter, as 2010 and 2012 statements were published. ATV-related fractures rose 14% yearly between 1997 and 2002, then dropped 15% from 2007 to 2010 following yearly AAP or AAOS statements from 2004 to 2007. From 2010 to 2014, the injury rate held constant during which time 2010, 2013, and 2014 statements were published. Lawnmower injury rates did not fall despite statements in 1998 and 2001 and a poster campaign in 2001. A 25% drop from 2007 to 2008 coincided with an AAOS statement in 2008. Fracture rates further dropped 31% from 2009 to 2011 and 21% from 2012 to 2014, amidst 2012 and 2014 statements. For ATV-related and lawnmower-related injuries, more male individuals were affected than female individuals, and for ATVs alone, injury rates increased with age.

CONCLUSIONS

Although AAOS/AAP statements did not universally coincide with dropping fracture rates, statements often were associated with substantial decreases in following years. This is likely because injury prevention messages are dispersed from providers to the public over time and outcomes depend on highly variable patient behaviors.

Child deaths of undetermined intent: An analysis of circumstances using Illinois Violent Death Reporting System data

BACKGROUND

There is little information available about the circumstances surrounding the deaths of children aged 0 to 14 years in which the manner of death is of undetermined intent.

METHODS

We analyzed data collected in the Illinois Violent Death Reporting System to describe victim demographics, location of injury, seasonality, day of week, and circumstances surrounding the victims' deaths.

RESULTS

From 2005 to 2010 in Cook County, Illinois, 192 cases were identified of children aged 0 to 14 years, in which the manner of death was of undetermined intent. The majority of cases were younger than 1 year (81%), male (62%), and non-Hispanic black (66%); occurred in the City of Chicago (65%); and also occurred most frequently during the months of May (15%) and July (13%) and on Sunday (19%). Circumstances of note were having information on the location of death available for the victim (90%); scene investigation was not performed/unknown/not documented (81%); and the victim not presenting with red petechiae (84%). By ethnicity, a lower proportion of Hispanic victims had parental drug information available compared with non-Hispanic victims (17% and 40%, respectively; p = 0.017); Hispanic victims were more likely than non-Hispanic victims to have a documented acute illness at the time of injury leading to death (57% and 33%, respectively; p = 0.015). The availability of scene information and the successful contact of one or both parents of the victim following the victim's death varied by location.

CONCLUSIONS

No public health surveillance system exists for the collection of this type of death. There is not enough information provided to develop an effective intervention. The systematic, thorough collection of information surrounding these deaths is necessary to pinpoint possible contributing mechanisms of death for these children.

Age Legislation and Off-Road Vehicle Injuries in Children

BACKGROUND AND OBJECTIVES

In 2010, the Massachusetts Legislature passed a comprehensive law that restricted off-road vehicle (ORV) use by children <14 years old and regulated ORV use by children up to the age of 18 years. We aimed to examine the impact of the 2010 Massachusetts law on the rates of ORV-related injuries.

METHODS

A retrospective analysis was performed of Massachusetts emergency department (ED) and inpatient discharges between 2002 and 2013 as found in the Center for Health Information and Analysis database by using external causes of injury codes specific to ORV-related injuries. Yearly population-based rates were compared before and after the implementation of the law (2002-2010 vs 2011-2013) by using Poisson regression analysis and segmented regression.

RESULTS

There were 3638 ED discharges and 481 inpatient discharges for ORV-related injuries in children across the 12-year study period. After the implementation of the law, the rate of ED discharges declined by 33% in 0- to 9-year-olds, 50% in 10- to 13-year-olds, and 39% in 14 to 17-year-olds (P < .0001). There was no significant decline in ED discharges for 25- to 34-year-olds. Inpatient hospital discharges were also reduced by 41% in 0- to 17-year-olds after implementation (P < .001).

CONCLUSIONS

As compared with adults (ages 25-34 years), the population-based ORV-related injury rate of residents <18 years old significantly declined after the passage of legislation that imposed age restrictions and other safeguards for youth riders.

Using Geospatial Mapping to Determine the Impact of All-Terrain Vehicle Crashes on Both Rural and Urban Communities

INTRODUCTION

Deaths and injuries from all-terrain vehicle (ATV) crashes result in approximately 700 deaths each year and more than 100,000 emergency department (ED) visits. Common misconceptions about ATV crashes are a significant barrier to injury prevention efforts, as is the lack of key information about where and how crashes occur. The purpose of this study was to determine ATV crash patterns within a state, and to compare and contrast characteristics of these crashes as a function of crash-site rurality.

METHODS

We performed descriptive, comparative, and regression analyses using a statewide off-road vehicle crash and injury database (2002-2013). Comparisons were performed by rurality as defined using the Rural Urban Commuting Area (RUCA) coding system, and we used geographic information system (GIS) software to map crash patterns at the zip code and county levels.

RESULTS

ATV crashes occurred throughout the state; 46% occurred in urban and 54% in rural zip code areas. Comparisons of rider and crash characteristics by rurality showed similarities by sex, age, seating position, on vs. off the road, and crash mechanism. Conversely, helmet use was significantly lower among victims of isolated rural crashes as compared to other victims (p=0.004). Crashes in isolated rural and small rural areas accounted for only 39% of all crashes but resulted in 62% of fatalities. In both rural and urban areas, less than one-quarter of roadway injuries were traffic related. Relative crash rates varied by county, and unique patterns were observed for crashes involving youth and roadway riders. During the study period, 10% and 50% of all crashes occurred in 2% and 20% of the state's counties, respectively.

CONCLUSION

This study suggests that ATV crashes are a public health concern for both rural and urban communities. However, isolated rural ATV crash victims were less likely to be helmeted, and rural victims were over-represented among fatalities. Traffic was not the major factor in roadway crashes in either rural or urban areas. Unique crash patterns for different riding populations suggest that injury prevention experts and public policy makers should consider the potential impact of geographical location when developing injury prevention interventions.

Pediatric ATV Injuries in a Statewide Sample: 2004 to 2014

OBJECTIVES

To establish the incidence, mortality rate, and fracture location of pediatric patients injured while using an all-terrain vehicle (ATV) over an 11-year period.

METHODS

A retrospective study using a state trauma database for patients ages 0 to 17 years who sustained injuries while using an ATV. Thirty-two pediatric and adult trauma centers within the state were evaluated from January 1, 2004, to December 31, 2014.

RESULTS

The inclusion criteria were met by 1912 patients. The estimated mean annual incidence during the period of the study was 6.2 patients per 100 000 children in the pediatric population <18 years of age. There was a decrease of 13.4% in the mean incidence when comparing the first 5 years of the study with the last 6 years. The median age of patients was 14 years. The median hospital length of stay and injury severity score were 3 days and 9, respectively. There were 28 fatalities (1.5%). The mean mortality incidence was 0.09 deaths per 100 000 children and remained relatively constant. The majority of patients (55.4%) sustained at least 1 bone fracture at or below the cervical spine. The femur and tibia were more commonly fractured (21.6% and 17.7% of the patients, respectively).

CONCLUSIONS

Despite current guidelines by the American Academy of Pediatrics, patients younger than 16 years of age remain victims of ATV injuries. Although there was a 13.4% reduction in the incidence of ATV-related injuries in recent years, continued preventive guidelines are still necessary to avert these injuries in children and adolescents.

Engaging Agribusinesses: Feasibility and Cost of an ATV Safety Poster Project

OBJECTIVES

All-terrain vehicle (ATV)-related deaths and injuries continue to be a significant problem. Influential change agents such as agribusinesses could be important partners for improving safety behaviors among rural ATV users. Our objective was to determine how effectively an injury prevention project could engage agribusinesses through the postal service and to assess their willingness to display a safety poster.

METHODS

One thousand two hundred forty-four agribusinesses received an ATV safety poster and a postcard survey by mail. A randomized sampling of these businesses was surveyed by telephone 4-7 weeks later. Telephone survey questions included whether they recalled receiving the poster, and if so, whether, where and how long the poster was displayed.

RESULTS

One hundred six postcards were returned. Of the 192 eligible business persons contacted by telephone, 89% agreed to participate. Approximately one-third of telephone survey participants recalled receiving the poster. Among these, 81% with walk-in customers posted it, and 74% still had it displayed 1 month later. Of participants who did not recall receiving the poster, 83% stated they would have displayed the poster. The cost of displaying each poster in a business was 16.6 cents/day during the first month. Final costs/day would be much less because of continued display.

CONCLUSION

A high percentage of agribusinesses displayed or would have displayed an ATV safety poster, and most displayed it beyond 1 month. Unfortunately, participant recruitment via postal delivery alone was challenging. Nevertheless, mass mailing of injury prevention materials to be displayed in the retail setting may be a low cost method for raising safety awareness.

Pediatric moped-related injuries in the United States from 2002 to 2014: Age-related comparisons of mechanisms and outcomes

Mopeds are a popular means of transportation, especially in urban areas. However, few studies have investigated moped-related injuries in the United States. This study's goal was to compare the crash mechanisms and injuries suffered in moped-related crashes involving youth versus adults, as well as between younger and older children.

INTRODUCTION

Mopeds are a popular means of transportation, especially in urban areas. However, few studies have investigated moped-related injuries in the United States. This study's goal was to compare the crash mechanisms and injuries suffered in moped-related crashes involving youth versus adults, as well as between younger and older children.

METHODS

Descriptive and comparative analyses were performed using National Electronic Injury Surveillance System (NEISS) data and additional variables coded from injury narratives. Multivariate regression analyses were used to calculate adjusted odds ratios (aORs) and 95% confidence intervals (CIs) for categorical outcomes, controlling for significant covariates.

RESULTS

From 2003 to 2014, there were 779 youth (17 years or younger) and 2,453 adult moped-related emergency department visits in the database. The number of youth injured remained relatively constant over time, while the number of adult victims doubled. Relative to 14- to 17-year olds, victims younger than 14 years were more commonly female (p = 0.037) and non-Caucasian (p = 0.008). Victims 14 to 17 years of age had a higher proportion of brain injuries (p = 0.012) and were more commonly in motor vehicle collisions (p = 0.02), as compared to younger victims. Relative to adults, youth crashes occurred more commonly in the summer (p < 0.0001), and off the street/road (p < 0.0001). Logistic regression analysis showed crashes on streets/roads were two and a half times more likely to involve victims who were 14 to 17 years of age as compared to those younger (aOR, 2.55; CI, 1.64-3.97). Additionally, male youths were twice as likely as females to have a motor vehicle collision (aOR, 1.97; CI, 1.19-3.24), and pediatric crashes were approximately twice as likely to result in extremity injuries as compared to adult crashes (aOR, 1.95; CI, 1.19-3.20).

CONCLUSION

Differences in crash mechanism and injuries sustained between two youth age groups and between youths and adults indicate the importance of targeted injury prevention efforts. This would include improved operator training and standardized, evidence-based, well-enforced safety legislation.

Analysis of All-Terrain Vehicle Trauma Data: Implications for Increased Regulation and Injury Prevention

To determine the incidence and severity of all-terrain vehicle crashes (ATVCs) compared with motorcycle crashes (MCCs) in all critically injured patients. Prospective data were retrospectively reviewed on 1840 patients involved in ATVCs and MCCs admitted to a rural level one trauma center over 16 years. ATVC patients (n = 655) were younger (25 vs 38, P < 0.0001), more likely female (20% vs 11%, P < 0.001), less severely injured (13.5 vs 16, P < 0.0001), had similar Glasgow Coma Score (13.3 vs 13.4, p = NS), less helmet use (6% vs 69%, P < 0.0001), more closed head injuries (59.7% vs 54.3%, P < 0.05), more facial injuries (16.9% vs 12.5%, P < 0.05), and lower mortality rate (2.8% vs 5.9%, P < 0.01) compared with MCC patients (n = 1172). Pediatric patients involved in ATVC were more common (29.8% vs 4.8%, P < 0.001), had decreased helmet use (12% vs 59%, P < 0.001) and decreased mortality (3.5% vs 14.3%, P < 0.01). Further injury prevention efforts regarding helmet use and increased regulations regarding ATVCs are needed to decrease the morbidity associated with these recreational vehicles.

Age and the risk of All-Terrain Vehicle-related injuries in children and adolescents: a cross sectional study

BACKGROUND

The study was designed to determine if youth <16 years are at a greater risk of serious injuries related to all-terrain vehicle (ATV) use compared to older adolescents and adults.

METHODS

We performed cross sectional study of children and adults presenting to pediatric and adult emergency departments between 1990 and 2009 in Canada. The primary exposure variable was age <16 years and the primary outcome measure was moderate to serious injury determined from physician report of type and severity of injury.

RESULTS

Among 5005 individuals with complete data, 58% were <16 years and 35% were admitted to hospital. The odds of a moderate to serious injury versus minor injury among ATV users <16 years of age was not different compared with those ≥16 years of age (OR: 0.94; 95% CI: 0.84, 1.06). After adjusting for era, helmet use, sex and driver status, youth <16 years were more likely to present with a head injury (aOR: 1.45; 95% CI: 1.19-1.77) or fractures (aOR: 1.60; 95% CI: 1.43-1.81), compared with those ≥16 years. Male participants (aOR: 1.21; 95% CI: 1.06-1.38) and drivers (aOR: 1.30, 95% CI: 1.12-1.51) were more likely to experience moderate or serious injuries than females and passengers. Helmet use was associated with significant protection from head injuries (aOR: 0.59; 95% CI: 0.44-0.78).

CONCLUSIONS

Youth under 16 years are at an increased risk of head injuries and fractures. For youth and adults presenting to emergency departments with an ATV-related injury, moderate to serious injuries associated with ATV use are more common among drivers and males. Helmet use protected against head injuries, suggesting minimum age limits for ATV use and helmet use are warranted.

All-terrain vehicle safety knowledge, riding behaviors and crash experience of Farm Progress Show attendees

INTRODUCTION

Although all-terrain vehicles (ATVs) are very popular in rural areas for both recreation and work purposes, the epidemiology of agricultural ATV use remains largely unknown.

METHODS

Farm Progress Show attendees in 2012 (Boone, Iowa) and 2013 (Decatur, Illinois) were surveyed about ATVs, including riding behaviors, crash history, and safety knowledge. Descriptive and comparative analyses were performed (N=635 surveys).

RESULTS

Over half of those surveyed lived on a farm and more than 90% had ridden on an ATV. Sixty-one percent rode at least once a week and 39% reported riding almost daily. Males and respondents who lived on farms were significantly more likely to be ATV riders. Regarding unsafe behaviors, >80% of ATV users had ridden with a passenger, 66% had ridden on a public road, and nearly one-half never or almost never wore a helmet. Nearly 40% reported having been in a crash. Multivariable logistic regression analysis of adult respondent's data showed males and younger adults were both more likely to report having crashed. In addition, those reporting riding on public roads (but not having ridden with passengers) were nearly five times more likely and respondents who reported both riding on public roads and having ridden with passengers were approximately eight times more likely to have been in a crash as compared to those not reporting these unsafe behaviors. Safety knowledge did not necessarily correspond with safer behaviors; 80% who knew there should be no passengers on an ATV still had ridden with extra riders.

CONCLUSION

ATV use is prevalent in rural populations and most riders report engaging in unsafe riding behaviors.

PRACTICAL APPLICATIONS

These findings may be used to inform ATV safety education and training programs targeted toward agricultural communities, with the goal of reducing occupational ATV-related deaths and injuries and their substantial economic costs.

All-terrain vehicle fatalities on paved roads, unpaved roads, and off-road: Evidence for informed roadway safety warnings and legislation

OBJECTIVE

All-terrain vehicles (ATVs) are designed for off-highway use only, and many of their features create increased risk with roadway travel. Over half of all ATV-related fatalities occur on roadways, and nonfatal roadway crashes result in more serious injuries than those off the road. A number of jurisdictions have passed or have considered legislation allowing ATVs on public roadways, sometimes limiting them to those unpaved, arguing that they are safe for ATVs. However, no studies have determined the epidemiology of ATV-related fatalities on different road surface types. The objective of the study was to compare ATV-related deaths on paved versus unpaved roads and to contrast them with off-road fatalities.

METHODS

Retrospective descriptive and multivariable analyses were performed using U.S. Consumer Product Safety Commission fatality data from 1982 through 2012.

RESULTS

After 1998, ATV-related deaths increased at twice the rate on paved versus unpaved roads. Still, 42% of all roadway deaths during the study period occurred on unpaved surfaces. States varied considerably, ranging from 18% to 79% of their ATV-related roadway deaths occurring on unpaved roads. Paved road crashes were more likely than those on unpaved surfaces to involve males, adolescents and younger adults, passengers, and collisions with other vehicles. Both the pattern of other vehicles involved in collisions and which vehicle hit the other were different for the 2 road types. Alcohol use was higher, helmet use was lower, and head injuries were more likely in paved versus unpaved roadway crashes. However, head injuries still occurred in 76% of fatalities on unpaved roads. Helmets were associated with lower proportions of head injuries among riders, regardless of road surface type. Relative to off-road crashes, both paved and unpaved roads were more likely to involve collisions with another vehicle. The vast majority of roadway crashes, however, did not involve a traffic collision on either paved or unpaved roads.

CONCLUSIONS

Although differences were observed between paved and unpaved roads, our results show that riding on either represented significantly greater dangers than riding off the road. Many vehicle warnings specifically mention the risks of paved but not unpaved roads, yet we found 23 states with half or more of their roadway deaths on unpaved surfaces. Safety warnings should explicitly state the dangers of roadway riding regardless of surface type. These data further support laws/ordinances greatly restricting ATV riding on all types of public roadways.

Characteristics of Side-by-Side Vehicle Crashes and Related Injuries as Determined Using Newspaper Reports from Nine U.S. States

Side-by-side (SxS) vehicles have become increasingly popular, but there are few reports on injury epidemiology. Newspaper reports of SxS and all-terrain vehicle (ATV) crashes were analyzed for nine U.S. states from 2009 to 2011, including comparisons between the two vehicle types. Seventy-nine SxS crashes involving 104 injured victims were identified; three-fourths were males. There was a relatively high percentage of injured passengers (37%), and a higher proportion of female victims were passengers as compared to males (p = 0.015). Children <16 years of age were 44% of those injured and had the highest proportion of both passenger and operator victims as compared to other age groups. Over half of the crashes occurred on roadways; nearly two-fifths occurred at night. As compared to adults, a lower percentage of crashes involving youth were at night (p = 0.0037) but the percentages on roadways were similar. Only one in five roadway SxS crashes involved a collision with a motorized vehicle. Rollovers were the most common mechanism (50%). Two-thirds of victims were ejected, and one-half were struck or pinned by the vehicle. Twenty-eight deaths (27%) were reported. Although most current SxSs have roll bars, lack of safety belt use has likely reduced their benefit. Children should be prohibited from operating SxSs.
