Abstract

Objectives

All Terrain Vehicles (ATVs) are increasing in popularity and becoming larger and faster at a production level. As a Level I Trauma Center, we perceived a disproportionately high volume of ATV-related admissions. Our goal was to study injury patterns and severity in adult and pediatric populations.

Methods

All ATV-related trauma admissions at a single Level I trauma center were retrospectively analyzed over a seven-year period.

Results

On-road incidents were more likely to result in a higher average Injury Severity Score (ISS) (p < 0.05). Higher ISS also occurred in children, un-helmeted, and impaired rider groups (p < 0.05). The pediatric population was more likely to have a major head injury (62.5% of children versus 31.8% of adults, p < 0.05) while thoracic injury was more common in adults (43.4% of adults versus 16.7% of children, p < 0.05). Death rates were similar in both adult and pediatric populations.

Conclusion

ATV-related injuries vary depending on incident characteristics and patient populations. On-road use incurs a significant increase in injury severity. The pediatric population is significantly more likely to incur a severe injury and the presenting injury pattern differs from the adult population. Knowledge of population and presentation trends can help direct trauma care providers in the care and management of injured ATV riders.

Introduction

First introduced to the US consumer in 1971, All Terrain Vehicles (ATVs) have gained widespread popularity with a currently estimated 10.6 million ATVs in use in the United States (United States Consumer Product Safety Commission, 2014). ATV models are made in a variety of sizes and types which can weigh in excess of 850 pounds and travel at speeds of 85mph or greater especially with off-market modifications (Consumer Federation of America, 2007). Used as both a recreational vehicle and a work utility vehicle, ATVs can provide sport entertainment, and increase work productivity. Yet, despite efforts to promote safe riding practices and industry innovations in protective equipment, ATV related accidents continue to demonstrate an increasing trend in occurrence.

Background

Between 1997 and 2004 the number of hospitalizations for ATV-related injuries quadrupled in the United States (Breslau et al., 2012). Within this admission data, hospitalizations for children with ATV-related injuries was found to increase from roughly 1600 to over 4000 admissions (Breslau et al., 2012) The pediatric population is inherently at more risk due to their smaller size and the considerable strength, psychomotor skills, and cognitive judgment required to operate such a vehicle. Even

Methods

With Institutional Review Board approval all ATV-related admissions from June 1999 to August 2005 at a Level I trauma center were identified. Patient clinical information, as well as data obtained from patient questionnaires, were retrospeectively. Questionnaires were obtained by the trauma staff and information gathered from the patients or their family members either at admission, during their hospital stay, or during post-discharge follow up. The questionnaires specifically evaluated for:

Results

From 1999 to 2005, 225 ATV-related trauma admissions were identified. Both pediatric and adult admissions were highest in 2004, which was more than double the admission rates seen in 2001 (Fig. 1). All age ranges were predominantly male with a total of 179 males and a total of 46 females. Adults accounted for 57.3% of the admissions (n = 129) and children, defined as age 17 or younger, accounted for 42.7% (n = 96). The age of pediatric admissions ranged from 4 to 17 with a mean age of 12.5 (

Discussion

ATV-related accidents are of growing concern for healthcare providers as the morbidity and mortality resulting from the associated injuries are significant. From 2000 to 2010 the annual death toll from ATV-related incidents was as high as 833 per year with deaths in children as high as 182 per year; accounting for nearly 24% of total reported deaths in all age groups(United States Consumer Product Safety Commission, 2014). Survey data from Jennissen et al., revealed at least 75% of adolescents,

Conclusion

With an estimated 10.2 million ATV's in the United States, the products' increasing trend in popularity, and manufacture upgrades in horsepower and speed, the incidence of ATV-related accidents are projected to increase (Breslau et al., 2012). The machines are large, fast, difficult to control, often used in a manner for which they were not designed or intended, and are commonly operated by children, thus contributing to accidents resulting in significant injury. Attempts to enact legal

Ethical statement

The study design and procedures were approved by the Medical Center Institutional Review Board.

    This lack of helmet use is even more alarming for the pediatric population. In another level I trauma center study, researchers found that 62.5% of children had a major head injury, compared with 31.8% of adults (31). One measure is the use of state laws regulating ATVs.
