Unintentional non-traffic injury and fatal events: Threats to children in and around vehicles

Joint Effect of Heavy Vehicles and Diminished Light Conditions on Paediatric Pedestrian Injuries in Backover Crashes: A UK Population-Based Study

Backover crashes cause considerable injuries especially among young children. Prior research on backover crashes has not assessed the joint effect of heavy vehicles and diminished light conditions on injuries. By analysing the United Kingdom STATS19 crash dataset from 1991 to 2020, this study focused on backover crashes involving paediatric cyclists or pedestrians aged ≤17 years and other motorised vehicles. By estimating the adjusted odds ratio (AOR) of multiple logistic regression models, pedestrians appeared to have 82.3% (95% CI: 1.78-1.85) higher risks of sustaining killed or serious injuries (KSIs) than cyclists. In addition, casualties involved in backover crashes with heavy vehicles were 39.3% (95% CI: 1.35-1.42) more likely to sustain KSIs than those involved in crashes with personal cars. The joint effect of heavy vehicles and diminished light conditions was associated with a 71% increased probability of sustaining KSIs (AOR = 1.71; 95% CI: 1.60-1.83). Other significant joint effects included young children (aged 0 to 5 years) as pedestrian (AOR = 1.92; 95% CI: 1.87-1.97), in diminished light conditions (AOR = 1.23; 95% CI: 1.15-1.31), and with heavy vehicle (AOR = 1.37; 95% CI: 1.28-1.47).

Pediatric Heatstroke Fatalities Caused by Being Left in Motor Vehicles

OBJECTIVES

Fatalities due to being left in motor vehicles is an important cause of pediatric mortality. Few studies in the medical literature focus on this topic. This study aims to describe the circumstances surrounding these deaths, to determine their geographic distribution, and to evaluate the legal consequences for those responsible.

METHODS

This is a retrospective cohort study of individuals ≤14 years old who died of heatstroke after being left in motor vehicles from 1990 through 2016 using a database provided by KidsAndCars.org. Descriptive data and specified outcomes regarding victims and responsible individuals were recorded.

RESULTS

Of the 541 cases included for analysis, 528 fatalities involved a single victim and 26 fatalities involved 2 or more victims left in a vehicle. Of all fatalities, 54.4% were male and the mean age was 16.4 (±13.7) months. The responsible individual(s) unknowingly left the victim(s) in the vehicle in 78.2% of cases and knowingly left the victim(s) in 16.6% of cases. A single individual was responsible for leaving the victim(s) in 88.9% of cases. The cases were noted in 45 of 50 states and most commonly occurred in Texas (15%), Florida (12%), and California (7%). Criminal charges against the responsible individual(s) occurred in 58.2% of cases.

CONCLUSIONS

Pediatric fatalities due to being left in motor vehicles most commonly occur when a caregiver leaves a child unknowingly in a home parking area. These fatalities occur most often in Texas, Florida, and California. Responsible individuals are frequently charged with a crime.

Firearm-Related Deaths in Multnomah County, Oregon, 2010-2016: Linking Medical Examiner Data to State Vital Records Data

OBJECTIVES

Violence due to firearms is a substantial public health problem. Death data from medical examiner and vital records were linked to evaluate the use of medical examiner data to augment routine surveillance and determine any differences in sex, age, manner of death, or race and ethnicity between the 2 data systems.

MATERIALS AND METHODS

Medical examiner data were searched for keywords of interest, and vital records data were obtained and linked for deaths occurring in Multnomah County, Oregon, from January 1, 2010, through December 31, 2016. Both data sets were compared for the number and proportion of firearm-related deaths by sex, age, manner of death, and race/ethnicity. Sensitivity and positive predictive values were calculated for variables that had discordant results.

RESULTS

A total of 568 firearm-related deaths were identified in the medical examiner data. After matching with manual review, the 2 data systems had 100% case agreement. A reverse match showed that most cases not found in medical examiner data were due to transfer of case jurisdiction. The 2 systems matched nearly perfectly in sex, age, and manner of death but differed in characterization of race and ethnicity. Sensitivity was 62% for Hispanic ethnicity but 93% for white and black race.

PRACTICE IMPLICATIONS

Using medical examiner data was a useful way to augment routine surveillance of firearm-related deaths in our jurisdiction in close to real time. However, caution is needed when analyzing data by subgroups because of discordant classifications of race between the data systems.

Vehicular Hyperthermia-A Highly Preventable and Potentially Fatal Problem

A child dying of heat injury due to being left unattended in a motor vehicle is a needless tragedy. Each year in the United States an average of 38 children mostly younger than age 2 years die of vehicular hyperthermia, frequently the result of a parental lapse of attention and not intentional neglect. Serious illness results quickly from exposure to rising heat within the passenger compartment, even on days when the temperature is fairly moderate. Prevention is paramount in addressing this problem and can best be accomplished by a combination of technological means, such as passive warning systems, laws that make leaving a child in a car alone illegal, and public education campaigns.
