Injury severity in pediatric all-terrain vehicle-related trauma in Nova Scotia

Alcohol is a risk factor for helmet non-use and fatalities in off-road vehicle and motorcycle crashes

OBJECTIVES

Off-road vehicle (ORV) and motorcycle use is common in Canada; however, risk of serious injury is heightened when these vehicles are operated without helmets and under the influence of alcohol. This study evaluated the impact of alcohol intoxication on helmet non-use and mortality among ORV and motorcycle crashes.

METHODS

Using data collected from the Nova Scotia Trauma Registry, a retrospective analysis (2002-2017) of ORV and motorcycle crashes resulting in major traumatic brain injury was performed. Patients were grouped by blood alcohol concentration (BAC) as negative (< 2 mmol/L), legally intoxicated (2-17.3 mmol/L) or criminally intoxicated (> 17.3 mmol/L). Logistic regression models were constructed to test for helmet non-use and mortality.

RESULTS

A total of 424 trauma patients were included in the analysis (220 ORV, 204 motorcycle). Less than half (45%) of patients involved in ORV crashes were wearing helmets and 65% were criminally intoxicated. Most patients involved in motorcycle crashes were helmeted at time of injury (88.7%) and 18% were criminally intoxicated. Those with criminal levels of intoxication had 3.7 times the odds of being unhelmeted and were 3 times more likely to die prehospital compared to BAC negative patients. There were significantly increased odds of in-hospital mortality among those with both legal (OR = 5.63), and criminal intoxication levels (OR = 4.97) compared to patients who were BAC negative.

CONCLUSION

Alcohol intoxication is more frequently observed in ORV versus motorcycle crashes. Criminal intoxication is associated with helmet non-use. Any level of intoxication is a predictor of increased in-hospital mortality.

Epidemiology and factors associated with mortality among pediatric major trauma patients in Nova Scotia: A 17-year retrospective analysis

BACKGROUND

Major traumatic injury in the pediatric population requires further evaluation to improve patient outcomes. Relatively few Canadian studies have investigated pediatric trauma using population-based data. Our objectives were to describe the epidemiology of pediatric major trauma in Nova Scotia and identify factors associated with in-hospital mortality.

METHODS

Retrospective cohort study of pediatric major trauma patients (age <18 years) injured in Nova Scotia over a 17-year period (April 2001-March 2018). Data were collected from the Nova Scotia Trauma Registry. Characteristics were compared between patient subgroups using t-tests, chi-square analyses and Fisher's exact test. Temporal trends were evaluated using the Mann-Kendall test. Incidence and mortality rates were mapped using ArcGIS Pro. A multivariate logistic regression model was created to assess for factors associated with in-hospital mortality.

RESULTS

A total of 1258 injuries were observed over the 17-year study period. The incidence of pediatric major trauma was 41.7 per 100,000 person-years. Most patients were male (819/1258; 65.1 %) and resided in urban areas (764/1258; 60.7 %). Blunt trauma accounted for 86.2 % (1084/1258) of injuries, and motor vehicle collisions were the most common cause (448/1258; 35.6 %). Incidence and mortality rates were highest in the 15-17 year age group, with a trend towards increasing incidence among females (p = 0.011). Mortality was 17.2 % (217/1258) of patients; 10.9 % (137/1258) died pre-hospital. No trends were detected in mortality rates. The regression model showed increased odds of in-hospital mortality for every point increase in the ISS (OR 1.05; 95 % CI 1.02 to 1.09) and for every unit decrease in scene GCS (OR 0.63; 95 % CI 0.56-0.71). Rural patients were 2 times more likely to die in-hospital versus urban patients (OR 2.40; 95 % CI 1.01-5.69), and patients injured at home were 6 times more likely to die compared to those injured in other locations (OR 6.19; 95 % CI 1.01-38.11).

CONCLUSION

Pediatric trauma remains a major public health issue in Canada and beyond. Greater efforts are required to expand our understanding of trauma epidemiology and develop targeted injury prevention strategies, especially for rural inhabitants.

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.

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.

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.

All-terrain vehicle serious injuries and death in children and youth: A national survey of Canadian paediatricians

Background

All-Terrain Vehicles (ATVs) are a leading cause of serious injury in children and youth. Certain Canadian regions have implemented legislation to promote safety, including age restrictions, mandatory training and helmet use. Jurisdictions with more stringent ATV safety legislation have been shown to have reduced injury rates in the short term.

Objectives

To estimate the burden of ATV-related serious injury and death in Canada and to identify Canadian physicians' knowledge of ATV-related legislation, safety and health promotion practices.

Methods

A one-time survey was distributed to practicing paediatricians and paediatric subspecialists participating in the Canadian Paediatric Surveillance Program (CPSP) in October 2016.

Results

Of 2793 physicians contacted, 904 responded (32.4%). There were 181 reported cases of serious and/or fatal ATV-related injuries, including 6 deaths. Children aged 10 to 14 represented the most number of cases (n=82, 45.3%), followed by 15 to 19 (n=48, 26.5%) and 5 to 9 (n=40, 22.1%). Most cases occurred in July/August (48.3%) and May/June (25.2%), were in males (n=133, 78.2%), and occurred during recreational activity (n=139, 83.2%) or organized racing (n=6, 3.6%). In 99 cases (58.9%), the child was the driver of the ATV. Only two-thirds of respondents (67.5%) knew that ATVs should not carry passengers while under half (42.2%) never discussed ATV safety with their patients.

Conclusions

ATV-related injuries and deaths in Canadian children remain a serious public health problem. Education of health care practitioners, including paediatricians, is needed to promote safety. Despite efforts to reduce ATV-related injuries, there remains a significant number of serious injuries and/deaths related to their use.
