COVID-19 Pandemic Effects on the Epidemiology and Mortality of Pediatric Firearm Injuries; A Single Center Study.

The COVID-19 pandemic has been associated with increased firearm injuries amongst adults, though the pandemic's effect on children is less clearly understood. This cross-sectional study was performed at a Level 1 Pediatric Trauma Center and included youths 0-19 years. The trauma registry was retrospectively queried for firearm injuries occurring pre-COVID-19 pandemic (March 2015-February 2020). Baseline data was compared to prospectively collected data occurring during the COVID-19 pandemic (March 2020-March 2022). Fischer's exact, Pearson's Chi-square and/or correlation analysis was used to compare pre and post-COVID-19 firearm injury rates and intent, victim demographics and disposition. Temporal relationships between firearm injury rates and local COVID-19 death rates were also described. 413 pre-COVID-19 firearm injuries were compared to 259 pandemic firearm injuries. Victims were mostly Black males with a mean age of 13.4 years. Compared to the 5 years pre-pandemic, monthly firearm injury rates increased 51.5% (6.8 vs 10.3 shootings/month), including a significant increase (p = 0.04) in firearm assaults/homicides and a relative decrease in unintentional shootings. Deaths increased 29%, and there were significantly fewer ED discharges and more admissions to OR and/or PICU (p = 0.005). There was a significant increase in Black victims (p = 0.01) and those having Medicaid or self-pay (p<0.001). Firearm injury spikes were noted during or within the 3 months following surges in local COVID-19 death rates. The COVID-19 pandemic was associated with an increase in the frequency and mortality of pediatric firearm injuries, particularly assaults amongst Black children following surges in COVID death rates. Increased violence-intervention services are needed, particularly amongst marginalized communities. This is a prognostic study, evaluating the effects of the COVID-19 pandemic on pediatric firearm injuries, including victim demographics, injury intent and mortality. This study is retrospective and observational, making it Oxford Level III evidence.

Child Firearm Injury Circumstances and Associations With Violence Intervention Program Enrollment.

Pediatric firearm injuries are the leading cause of death among American children. While assault is the most commonly cited cause, few studies have investigated circumstances surrounding such injuries. Violence intervention programs (VIPs) have been utilized to combat firearm violence, though a similar lack of knowledge exists regarding possible associations between firearm injury circumstances and youth VIP enrollment. This cross-sectional study included children aged 6-17 y who presented to an urban level 1 pediatric trauma center with firearm injuries from 2014 to 2017. Victim demographics and enrollment in a VIP were obtained from medical records, as well as circumstances surrounding the injuries based on account of the victim, victim's family/friends, and/or police present at the hospital. Circumstances included location of the shooting, if the shooter was known to the victim, and if the shooting was confirmed by the victim or their contacts to have been accidental or an intentional assault. Medical record numbers were used to locate victims in our trauma registry in order to obtain their assigned international classification of disease codes. Wilcox-rank sum, Pearson's chi-squared and Fisher's exact tests were used to detect associations between demographics, VIP enrollment, and shooting circumstances. 156 victims of firearm injury were described, including primarily Black adolescent males. 72% of victims were shot outdoors by an unknown shooter, the motivation of which was unknown in 93% of cases. 36% of these shootings were "drive-by". The majority of victims received international classification of disease codes for assault, though shootings that were confirmed by the victim to have been intentional assaults were relatively uncommon (13.4%). Most children lived in the same zip code in which they were shot (71%), and three particular zip codes accounted for 40% of shootings. 26% of victims chose to enroll in the VIP, and those that were victims of confirmed assaults (odds ratio 3.5) as well as those admitted to the hospital (odds ratio 2.4) were significantly more likely to enroll. Based on victim account, children living in an urban setting are more frequently victims of unclearly motivated, outdoor neighborhood shootings rather than intentional assaults. More accurate understanding of the causes of pediatric firearm injuries should inform both recruitment into VIPs, as well as a balancing of VIPs with community-level interventions to address firearm violence.

The impact of the COVID-19 pandemic on pediatric firearm injuries in Colorado.

In 2019 firearm injuries surpassed automobile-related injuries as the leading cause of pediatric death in Colorado. In the spring of 2020, the COVID-19 pandemic led to community-level social, economic, and health impacts as well as changes to injury epidemiology. Thus, we sought to determine the impact of the COVID-19 pandemic on pediatric firearm injuries in Colorado. We conducted a retrospective review of pediatric firearm injured patients (≤ 18-years-old) evaluated at three trauma centers in Colorado from 2018-2021. Patients were stratified into two groups based on the time of their firearm injury: pre- COVID injuries and post- COVID injuries. Group differences were examined using t-tests for continuous variables and Chi Squared or Fisher's exact tests for categorical variables. Overall, 343 firearm injuries occurred during the study period. There was a significant increase in firearm injuries as a proportion of overall pediatric ED trauma evaluations following the onset of the COVID-19 pandemic (pre COVID: 5.18/100 trauma evaluations; post COVID: 8.61/100 trauma evaluations, p<0.0001). Assaults were the most common injury intent seen both pre and post COVID (70.3% vs. 56.7%, respectively); however, unintentional injuries increased significantly from 10.3% to 22.5% (p = 0.004) following the onset of the pandemic. Additionally, the COVID-19 pandemic was associated with a 177% increase in unintentional injuries in adolescents. Pediatric firearm injuries, particularly unintentional injuries, increased significantly in Colorado following the onset of the COVID-19 pandemic. The substantial increase in unintentional injuries among adolescents highlights the necessity of multi-disciplinary approaches to limit or regulate their access to firearms. Level III. Retrospective.

Wounding patterns in pediatric firearm fatalities.

Pediatric firearm injury became the leading cause of death among U.S. children in 2020. Studies evaluating wounding patterns in military and mass casualty shootings have provided insights into treatment and potential salvageability in adults, however, similar studies in the pediatric population do not exist. Hence, our study aimed to analyze wounding patterns of pediatric firearm fatalities and associated demographics and characteristics, such as place of death, to better understand pediatric firearm injuries, potential salvageability, and opportunities to reduce firearm deaths among vulnerable pediatric populations. A retrospective review of the National Violent Death Reporting System from 2005-2017 was performed on patients 18 and younger. Mortalities were stratified by patient age: <12 years and 13-18 years and by intent- homicide, suicide, and unintentional. Comparative and exploratory analyses of demographics, location of death and anatomic location of wounds were performed. Of 8,527 pediatric firearm mortalities identified, 4,728 were homicides, 3,180 were suicides and 619 were unintentional injuries. Suicide victims were most likely to be dead on scene and >90% of suicide victims suffered head/neck injuries. For victims of homicide, younger children were more likely to die on scene (61% vs 44% p < 0.001). The pattern of injury in homicides differed for younger children compared to adolescents, with younger children with more head/neck injuries and older children more thoracic, thoracoabdominal, abdominal, and junctional injuries. In both age groups, children with extremity, abdominal and thoracoabdominal injuries were more likely to die later in the emergency department or inpatient setting. Wounding patterns across pediatric firearm mortalities in the U.S. vary by age and intent. The majority of pediatric firearm deaths were due to head/neck injuries. Children with homicide and unintentional deaths had more wounding pattern variation, including more injuries to the thorax and abdomen, and a much lower rate of dead-on scene than suicide victims. Our study of wounding patterns among U.S. children killed by firearms highlights the complexity of these injuries and offers opportunities for tailored public health strategies across varying vulnerable pediatric populations.
