Pediatric vehicular heatstroke: An analysis of 296 cases from the National Fatality Review Case Reporting System

OBJECTIVES

To explore the National Fatality Review Case Reporting System (NFR-CRS) as a new data source to (1) characterize pediatric vehicular heatstroke (PVH) deaths among children <15 years of age reviewed by Child Death Review teams, and (2) identify factors independently associated with common PVH scenarios and incident locations.

METHODS

Data for 2005-2019 were used to characterize 296 PVH deaths. Frequencies and percentages were calculated to describe child, supervisor, and incident characteristics. Multiple logistic regression with and without imputation were carried out to identify factors associated with the two outcomes of interest: PVH scenario (left in vehicle vs. gained access) and incident place (supervisor workplace vs. other locations). Odds ratios and 95% confidence intervals (OR, 95% CI) were calculated.

RESULTS

Most children had been left unattended in vehicles (N = 225, 76.0%) and 13.5% (N = 40) had gained access independently. Children were most often male (N = 168, 56.8%), non-Hispanic White (N = 131, 44.3%), and <2 years of age (N = 172, 58.1%). Disability or chronic illness was noted for 4.7% (N = 14), 13.9% (N = 41) had a history of maltreatment, and 6.1% (N = 18) an open CPS case at the time of incident. Children left unattended were more likely to be <2 years of age (adjusted imputed OR 26.7, CI 7.3-97.2) and less likely to have an open CPS case (0.2, 0.0-0.4) and for the incident to occur at home (0.2, 0.1-0.9) compared to children who gained access. PVH deaths occurring at the supervisor's workplace were more likely to be <2 years of age (6.2, 2.4-15.8), to have occurred on a weekday (5.9, 1.7-20.9), and to have been supervised by their parent at the incident time (2.7, 1.1-6.7) compared to other locations.

CONCLUSIONS

The results align with previous PVH findings and added new information on child race/ethnicity, CPS action, disability/chronic illness, and maltreatment. With the exception of parents being more likely to be the supervisor in incidents occurring at home, which was expected, neither supervisor characteristics nor child race/ethnicity or sex were independently significant in multiple regression, suggesting that PVH is pervasive and that education campaigns should be similarly broad.

Firearm Deaths among Youth in the United States, 2007-2016

We sought to compare risk factors contributing to unintentional, homicide, and suicide firearm deaths in children. We conducted a retrospective review of the National Fatality Review Case Reporting System. We included all firearm deaths among children aged 0-18 years occurring from 2007 to 2016. Descriptive analyses were performed on demographic, psychosocial, and firearm characteristics and their relationship to unintentional, homicide, and suicide deaths. Regression analyses were used to compare factors contributing to unintentional vs. intentional deaths. There were 6148 firearm deaths during the study period. The mean age was 14 years (SD ± 4 years), of which 81% were male and 41% were non-Hispanic White. The most common manners of death were homicide (57%), suicide (36%), and unintentional (7%). Over one-third of firearms were stored unlocked. Homicide deaths had a higher likelihood of occurring outside of the home setting (aOR 3.2, 95% CI 2.4-4.4) compared with unintentional deaths. Suicide deaths had a higher likelihood of occurring in homes with firearms that were stored locked (aOR 4.2, 95% CI 2.1-8.9) compared with unintentional deaths. Each manner of firearm death presents a unique set of psychosocial circumstances and challenges for preventive strategies. Unsafe firearm storage practices remain a central theme in contributing to the increased risk of youth firearm deaths.

Social and Demographic Characteristics and the Contribution of Fireplay to Fire-Related Mortality Among Children in the U.S., 2004-2016

INTRODUCTION

This study seeks to describe the circumstances of fire deaths among children, identify deaths related to fireplay, and compare children whose deaths were related to fireplay with non-fireplay-related deaths.

METHODS

Children aged 1-14 years who died in a fire during 2004-2016 were identified from the National Fatality Review Case Reporting System. Social, demographic, and fire characteristics were described and then compared for children who died in fires caused by fireplay versus non-fireplay-related deaths. Unadjusted ORs and 95% CIs were calculated. Data were collected 2004-2018 and analyzed in 2019.

RESULTS

A total of 1,479 children who died in fires were identified. They were predominantly male (54%) and White (47%); 34% were Black. Two or more children died in 54% of incidents. Fires occurred most frequently in single-family homes (52%) and rental properties (37%); 23% were started by smoking materials or candles. Smoke alarm information was largely missing (42%) and noted to be present and working for only 82 deaths. Fireplay was responsible for 175 (12%) of the deaths. Compared with non-fireplay-related deaths, children who died in fireplay fires were more likely to be aged 1-4 years (OR=2.6, 95% CI=1.5, 4.3), male (OR=1.6, 95% CI=1.2, 2.2), have supervision documented as no, but needed (OR=8.8, 95% CI=4.1, 18.8), and have an open Child Protective Services case (OR=1.8, 95% CI=1.1, 3.0).

CONCLUSIONS

This study provides data on supervision and the role of fireplay in fatal fires among young children, offering information for the development of innovative primary prevention strategies and future research.

U-Shaped Pillows and Sleep-Related Infant Deaths, United States, 2004-2015

OBJECTIVES

To describe infant deaths where a u-shaped pillow was under or around an infant and to describe cases classified as Explained Suffocation.

METHODS

We examined demographics and circumstances of 141 infant deaths during 2004-2015 in the US National Fatality Review Case Reporting System with u-shaped pillows in the sleep environment.

RESULTS

Most infants were < 6 months old (92%), male (58%), non-Hispanic White (53%), and of the nine explained suffocation deaths, four occurred when the u-shaped pillow obstructed the infant's airway; five occurred when the infant rolled off the pillow and their airway was obstructed by another object.

CONCLUSIONS FOR PRACTICE

Although infrequent, infant deaths with u-shaped pillows have occurred. Health care providers may include discussion of the importance of caregivers following infant product packaging precautions and warning labels for commonly used consumer products, such as u-shaped pillows in their advice to caregivers.

Sudden unexpected infant deaths: sleep environment and circumstances

OBJECTIVES

We sought to describe the characteristics and sleep circumstances of infants who die suddenly and unexpectedly and to examine similarities and differences in risk factors among infants whose deaths are classified as resulting from sudden infant death syndrome (SIDS), suffocation, or undetermined causes.

METHODS

We used 2005 to 2008 data from 9 US states to assess 3136 sleep-related sudden unexpected infant deaths (SUIDs).

RESULTS

Only 25% of infants were sleeping in a crib or on their back when found; 70% were on a surface not intended for infant sleep (e.g., adult bed). Importantly, 64% of infants were sharing a sleep surface, and almost half of these infants were sleeping with an adult. Infants whose deaths were classified as suffocation or undetermined cause were significantly more likely than were infants whose deaths were classified as SIDS to be found on a surface not intended for infant sleep and to be sharing that sleep surface.

CONCLUSIONS

We identified modifiable sleep environment risk factors in a large proportion of the SUIDs assessed in this study. Our results make an important contribution to the mounting evidence that sleep environment hazards contribute to SUIDs.
