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

Animal-Related Injuries and Fatalities in the AgInjurynews Collection

OBJECTIVES

This research had three objectives. The first was to characterize reports of animal-related injuries found in the AgInjuryNews Dataset. The second objective was to compare the results of the AgInjuryNews reports to that of the Regional Rural Injury study. The third objective was to qualitatively and quantitatively assess the utility of using the AgInjuryNews database.

METHODS

A total of 104 reports on animal-related incidents representing 112 victims were sourced from AgInjuryNews. Chi square tests were performed comparing fatal and non-fatal injuries across age, gender, role in incident, animal, and activity. Additional chi square tests were performed to compare AgInjuryNews data with the results of Regional Rural Injury Study II across age, gender, animal, and activity. Utility of the dataset was assessed by examining the distribution of reports across states, the availability of articles, and qualitative observations.

RESULTS

Chi square results comparing fatal and nonfatal injuries were significant for victim gender. Results of the comparison of the two studies were significant for age and activity. A mismatch between the states with the highest populations of large animals and the states with the most reports in the AgInjryNews.org database was detected. Approximately 42% of reports the original articles were not accessible. Media bias plays a role in which cases are reported, but the size and accessibility of the dataset increases its utility.

CONCLUSION

Despite the limitations inherent to the dataset, the amount of freely accessible information and the level of insight provided make AgInjuryNews a valuable resource for agricultural injury research.

A New Source of Mutilating Hand Injuries: The Side-by-Side Utility Terrain Vehicle

BACKGROUND

Rates of mutilating hand injuries are increasing from accidents caused by all-terrain vehicles (ATVs) and the recently popularized side-by-side utility terrain vehicles (UTVs). Increasing surgeon familiarity with upper extremity (UE) injury patterns, severity, and outcomes following ATV and UTV accidents may improve patient care and advocacy.

METHODS

Retrospective comparisons of UE injury patterns, severity, hospital and intensive care unit (ICU) admission lengths, and number of operations were made between ATVs and UTVs. Findings were analyzed with Fisher exact tests, multivariate analysis of variance, analyses of variance with post hoc analyses, and multiple linear regressions.

RESULTS

A total of 154 cases were identified for inclusion (ATV, n = 87; UTV, n = 67). Patient ages ranged from 4 to 89 years. The UTV group contained significantly more hand and finger injuries, and more of the fractures were open ( P = 0.005, P < 0.001, and P < 0.001, respectively). Riders of UTVs had nearly three times as many mutilating hand injuries and a nearly ninefold increase in amputations compared with ATV riders ( P < 0.001 and P < 0.001, respectively). On average, the UTV group spent 2.5 additional days in the hospital, 0.91 additional days in an ICU, and had 1.3 additional operations ( P = 0.001, P = 0.007, and P < 0.001, respectively). Vehicle type was the only variable significantly correlated with days in the hospital, ICU, and number of UE operations ( P = 0.002, P = 0.008, and P < 0.001, respectively).

CONCLUSIONS

Hand surgeons are in a unique position to serve as forerunners for increasing public awareness of off-road vehicle risks and promoting rider safety. Collaborating with manufacturers and emergency care providers and directing teaching initiatives may improve patient outcomes.

Using motor vehicle crash records for injury surveillance and research in agriculture and forestry

PROBLEM

Fatal injuries in the agriculture, forestry, and fishing sector (AgFF) outweigh those across all sectors in the United States. Transportation-related injuries are among the top contributors to these fatal events. However, traditional occupational injury surveillance systems may not completely capture crashes involving farm vehicles and logging trucks, specifically nonfatal events.

METHODS

The study aimed to develop an integrated database of AgFF-related motor-vehicle crashes for the southwest (Arkansas, Louisiana, New Mexico, Oklahoma, and Texas) and to use these data to conduct surveillance and research. Lessons learned during the pursuit of these aims were cataloged. Activities centered around the conduct of traditional statistical and geospatial analyses of structured data fields and natural language processing of free-text crash narratives.

RESULTS

The structured crash data in each state include fields that allowed farm vehicles or equipment and logging trucks to be identified. The variable definitions and coding were not consistent across states but could be harmonized. All states recorded data fields pertaining to person, vehicle, and crash/environmental factors. Structured data supported the construction of crash severity models and geospatial analyses. Law enforcement provided additional details on crash causation in free-text narratives. Crash narratives contained sufficient text to support viable machine learning models for farm vehicle or equipment crashes, but not for logging truck narratives.

DISCUSSION

Crash records can help to fill research and surveillance gaps in AgFF in the southwest region. This supports traffic safety's evolution to the current Safe System paradigm. There is a conceptual linkage between the Safe System and Total Worker Health approaches, providing a bridge between traffic safety and occupational health.

PRACTICAL APPLICATIONS

Despite limitations, crash records can be an important component of injury surveillance for events involving AgFF vehicles. They also can be used to inform the selection and evaluation of traffic countermeasures and behavioral interventions.

An Assessment of Horse-Drawn Vehicle Incidents from U.S. News Media Reports within AgInjuryNews

Some old-order Anabaptist communities rely on animal-drawn vehicles for transportation and farm work. This research examines reports involving horse-drawn vehicles found in the AgInjuryNews dataset, which provides a publicly accessible collection of agricultural injury reports primarily gathered from news media. The goals of this research are to characterize the reports and to compare results with previous research to assess the utility of using AgInjuryNews to examine horse-drawn vehicle incidents. A total of 38 reports representing 83 victims were identified. Chi-square tests comparing victim and incident traits for fatal and nonfatal injuries were significant for the victim’s role in the incident, vehicle type, presence of a motor vehicle, rear-ending by a motor vehicle, spooked horses, a victim being run over or struck by a vehicle, and a victim being ejected or falling from a vehicle. Additional analysis of incidents involving horse-drawn farm equipment showed that a significantly higher proportion of off-road incidents were fatal compared to on-road incidents. The proportion of fatal injuries in the AgInjuryNews dataset was approximately 10 times higher than observed in a study using Pennsylvania Department of Transportation (DOT) data. Compared to previous research, the AgInjuryNews reports contained a higher proportion of incidents where a motor vehicle rear-ended a horse-drawn vehicle, and fewer cases of horse-drawn vehicles being struck by motor vehicles while crossing or entering a main road and making left turns. Reports of buggy crashes found in AgInjuryNews differed from those found in a Nexis Uni search in that the bulk of the articles from Nexis Uni referred to cases involving criminal charges for impaired driving or hit-and-run crashes. While it is evident that the reports included in the sample are incidents that media sources find compelling rather than comprehensive injury surveillance, it is possible to gain new insights using the AgInjuryNews reports.

Do All-terrain or Recreational Off-highway Vehicle Crashes Have a Higher Odds of Amputation?

BACKGROUND

Riding off-road vehicles is associated with the risk of injury to the extremities. There are two main types of four-wheel recreational off-road vehicles: quads or all-terrain vehicles (ATVs), which are essentially four-wheel off-road motorcycles, and recreational off-highway vehicles (ROVs), also colloquially referred to as utility terrain vehicles, which have side-by-side seating, higher maximum speeds, and a roll cage. There are multiple orthopaedic society position statements on ATVs, but none on ROVs. Perhaps this is because the injury patterns and differences between the two vehicles have not been elucidated.

QUESTIONS/PURPOSES

(1) What patient, vehicle (ROVs versus ATVs), and injury factors are associated with amputation? (2) What are the anatomic location distributions of fractures and amputations by vehicle type?

METHODS

Records of all patients in our hospital's billing system who had both a diagnostic code indicating an accident related to an off-road vehicle and one indicating an extremity or pelvic fracture between February 2014 and January 2020 were screened; this resulted in the identification of 328 patients with fractures resulting from off-road vehicle collisions. A total of 16% (51 of 328) of patients were excluded from the analysis because their injury did not involve either an ATV or an ROV; 277 patients were included in the final analysis. The following variables were collected: age at time of the injury, gender, BMI, vehicle type, Gustilo-Anderson type if applicable, amputation level if applicable, anatomic locations of injuries, ethanol level, and drug screen. ATV crashes accounted for 52% (145 of 277) of patients, and ROV crashes accounted for 48% (132 of 277). Patients from ATV crashes did not differ from those in ROV crashes in terms of mean age (24 ± 16 years versus 24 ± 13 years; p = 0.82), BMI (25 ± 7 kg/m 2 versus 26 ± 6 kg/m 2 ; p = 0.18), or gender (79% [114 of 145] men/boys versus 77% [102 of 132]; p = 0.79). Among patients who had a drug or ethanol screen, there was a higher percent of ATV riders who used marijuana (39% [19 of 49] versus 17% [7 of 42]; p = 0.04), but there were no differences in abnormal blood alcohol screen or abnormal nonmarijuana drug screen; however, these results were available in only about one-third of patients (99 of 277 for ethanol and 91 of 277 for drug screen). Statistical analysis was performed using logistic regression analysis for factors associated with amputation, with p values < 0.05 considered significant.

RESULTS

After controlling for differences in demographic factors, the stepwise increase in Gustilo-Anderson grade of open fracture (OR 9.8 [95% CI 3.6 to 27.0]; p < 0.001) and ROV vehicle type (OR 15.7 [95% CI 3.6 to 68.5]; p < 0.001) were both associated with amputation. There was no increase in the odds of amputation associated with age (OR 1.0 [95% CI 0.9 to 1.1]; p = 0.81), gender (OR 1.4 [95% CI 0.3 to 5.8]; p = 0.68), or BMI (OR 1.1 [95% CI 0.9 to 1.2]; p = 0.37). The most frequent ATV fractures occurred in the forearm and wrist (22% [45 of 203]), whereas most ROV injuries occurred through the metacarpals (41% [107 of 262] of fractures and 58% [18 of 31] of amputations).

CONCLUSION

ROV crashes are associated with a higher odds of amputation when compared with ATV crashes. Because most ROV injuries were in the forearm and below, this likely occurs when upper extremities are crushed and mangled under the roll cage in rollover ROV crashes. Because of this danger, we urge our orthopaedic societies to either update current ATV position statements to include ROVs or release separate statements on ROVs.

All-Terrain Vehicle-Related Emergency Department Visits: Interaction of Sex and Age, NEISS, 2019

BACKGROUND

Epidemiologic patterns of all-terrain vehicle (ATV)-related emergency department (ED) visits by male and female individuals may vary at different ages. To our knowledge, this has not been researched previously.

OBJECTIVE

The purpose of this study was to determine the interaction of sex and age differences in their association with ATV-related ED visits.

METHODS

Data from the 2019 National Electronic Injury Surveillance System were extracted for ATV-related ED visits, including sex, age, race, location of crash, injured body part, and whether alcohol was involved. Descriptive statistics and logistic regression analyses were conducted. We modeled sex in separate multivariable models, adjusting for the same independent variables.

RESULTS

There were an estimated 95,995 (unweighted n = 1999) ATV-related ED visits. There was a significant age-by-sex interaction in the association between ATV-related ED visits vs. other ED injuries, indicating that the effect of age on ATV-related ED visits differed by sex and vice versa. Overall, male individuals were 1.7 times as likely to have an ATV-related ED visit as female individuals. In the stratified analysis for female individuals, odds were substantially greater for girls younger than 18 years (adjusted odds ratio [AOR] 2.33; 95% confidence interval [CI] 1.61-3.69) and women aged 18-35 years (AOR 4.76; 95% CI 3.48-6.51) compared with woman older than 35 years. For men, odds were significant for ages 18-35 years (AOR 2.21; 95% CI 1.72-2.85) compared with men older than 35 years.

CONCLUSIONS

As newer ATVs become more powerful and faster, there is a need to know who is at greatest risk for ATV-related ED visits to develop policies and safety measures.

Effect of Quarantine and Reopening Measures on Pediatric Trauma Admissions During the 2019 SARS-CoV2 Virus Pandemic

BACKGROUND

Several studies have reported decreased trauma admissions and increased physical abuse in children resulting from stay-at-home measures. However, these studies have focused on a limited period after the implementation of lockdown policies. The purpose of this study was to examine the effect of quarantine and reopening initiatives on admissions for varying types of injuries in pediatric patients.

STUDY DESIGN

Registry data for an urban Level I pediatric trauma center were evaluated from April 1, 2018, to March 30, 2021. A timeline of local shutdown and reopening measures was established and used to partition the data into 6-month intervals. Data about demographics and injury characteristics were compared with similar intervals in 2018 and 2019 using appropriate statistical methodology for categorical, parametric, and nonparametric data.

RESULTS

A total of 3,110 patients met criteria for inclusion. A total of 1,106 patients were admitted the year after the closure of schools and nonessential businesses. Decreases in overall admissions and evaluations for suspected child abuse noted early in the pandemic were not sustained during shutdown or reopening periods. However, we observed a 77% increase in all-terrain vehicle injuries, along with a 59% reduction in sports injuries (chi-square [8, N = 3,110] = 49.7; p < 0.001). Significant shifts in demographic and payor status were also noted.

CONCLUSIONS

This is the first study to comprehensively examine the effects of quarantine and reopening policies on admission patterns for a pediatric trauma center in a metropolitan area. Total admissions and child abuse evaluations were not impacted. If shutdown measures are re-instituted, preventative efforts should be directed towards ATV use and recreational activities.

What about the Rest of Them? Fatal Injuries Related to Production Agriculture Not Captured by the Bureau of Labor Statistics (BLS) Census of Fatal Occupational Injuries (CFOI)

Surveillance of injuries in production agriculture is necessary to inform stakeholders about workplace hazards and risks in order to improve and advance injury prevention policies and practices for this dangerous industry. The most comprehensive fatal injury surveillance effort currently in the United States is the Bureau of Labor Statistics (BLS) Census of Fatal Occupational Injuries (CFOI), which covers occupational fatalities in all U.S. industries, including production agriculture. However, this surveillance does not include many categories of fatalities that occur during agricultural work or on production agriculture worksites. To better capture the human cost of production agriculture, the authors of this paper call for the collection of additional data with a broader scope that supplements, not replaces, the current CFOI. This paper describes challenges in surveillance, highlights key procedural gaps, and offers recommendations for advancing national surveillance of fatal traumatic injuries associated with production agriculture.

Nonfatal Agricultural Injuries Treated in Emergency Departments: 2015-2019

Utilizing emergency department admissions to estimate and describe agricultural injuries in the United States (U.S.) provides a unique view of one of the country's most dangerous occupations. This study characterizes and provides nationally representative estimates of persons with non-fatal agricultural-related injuries treated in emergency departments in the U.S.We conducted a cross-sectional study using U.S. Consumer Product Safety Commission, National Electronic Injury Surveillance System (NEISS) data for patients treated in emergency departments from January 1, 2015 to December 31, 2019. We queried all cases in the NEISS database using the location code "farm" and with a narrative search using relevant key words.An estimated 62,079 people were treated in an emergency department for agricultural related injuries. The mean age estimate in this population was 39 years-old, with ages ranging from 1 to 95. Almost two-thirds of patients were male, and almost 80% were white. Approximately 30% and 22% of those injured were youth and elderly patients, respectively. The majority of injuries occurred from April through September. The most common injury was fracture, followed by open wound or amputation. There were significant differences between the body parts injured in youth versus adult patients. The primary source of injury was in the vehicles category, with tractors being the dominant vehicle type.Agricultural vehicles remain a major source of injuries that require treatment in emergency departments. Previous methods of quantifying severe ag-related injuries were limited; our research utilized NEISS data to portray injury statistics more accurately.
