Individual and Neighborhood Level Characteristics of Pediatric Firearm Injuries Presenting at Trauma Centers in Colorado

Home and injury location discordance patterns in paediatric trauma: trends by mechanism, age and childhood opportunity level

BACKGROUND/AIMS

Understanding how injury mechanisms, demographics and neighbourhood characteristics differ based on injury location can improve data-driven injury prevention efforts. Our objective was to describe the association between mechanism of injury (MOI), patient age, neighbourhood characteristics and home and injury location discordance.

METHODS

We performed a retrospective, multicentre study of children transported by emergency medical services to 15 trauma centres in the county trauma registry from 2010 to 2021. Home-injury discordance (discordance between home and injury zip code) and neighbourhood opportunity discordance (more than one level difference across Childhood Opportunity Index (COI) levels) were trended by age and MOI. COI discordance by home COI for each MOI was also explored.

RESULTS

Among 13 020 paediatric traumas, home-injury discordance occurred in 48% of injuries, and was highest in sports/recreation (72%) and motorised travel (69%). COI discordance (27% overall) was frequent in sports/recreation (34%) and rarer in assault (22%). Assault and assault and motorised travel injuries occurred closer to home and with less COI discordance.

CONCLUSION

Unique patterns of injury risk and COI discordance by home COI level demonstrate that injury prevention efforts may require differential focus on factors affecting residents versus visitors of a neighbourhood depending on the MOI.

Pediatric firearm injuries and socioeconomic vulnerability before and during the COVID-19 pandemic

BACKGROUND

Pediatric firearm injuries disproportionately affect groups experiencing socioeconomic disadvantage. Firearm injuries increased during the COVID-19 pandemic, but the impact on communities by degree of socioeconomic disadvantage is unknown. We examined the association between socioeconomic vulnerability and change in pediatric firearm injuries before versus during the pandemic.

METHODS

This was a secondary analysis of a multicenter retrospective study comparing pediatric injuries pre- (March 17, 2019-December 31, 2020) versus during (March 15, 2020 - December 31, 2020) the COVID-19 pandemic. The parent study included injury-related visits to one of 40 Pediatric Emergency Departments in patients <18 years old. We examined firearm injuries as a proportion of all injuries. Deprivation Index (DI) was assigned using home zip code and divided into quartiles based on the distribution of DI in our total population, with deprivation increasing from quartile 1 (Q1, least deprivation) to quartile 4 (Q4, most deprivation). Kruskal-Wallis and Chi-square tests were used to compare variables of interest. Interrupted time series analysis was used to estimate pandemic effects on firearm injuries by DI quartile.

RESULTS

There were 1231 visits for firearm injuries. Mean DI was higher among firearm-injured than non-firearm-injured patients (0.43 vs. 0.35, p < 0.0001). Firearm injuries increased in proportion to all injuries pre- vs during pandemic (0.16 % vs 0.27 %, p < 0.0001). On interrupted time series analysis, the proportion of firearm injuries increased for Q2, Q3, and Q4. On subgroup analysis by intent, assault injuries as a proportion of all injuries increased from pre- to during COVID-19 for Q2 (3.32 % vs 6.94 %, ARD 3.62 %, 95 % CI 1.03, 6.20), Q3 (2.71 % vs 7.01 %, ARD 4.30, 95 % CI 1.99, 6.61), and Q4 (5.97 % vs 17.40 %; ARD 11.42, 95 % CI 0.19, 0.33). Unintentional injuries and injuries in youth 10-17 years old increased for Q2, Q3, and Q4.

CONCLUSIONS

The increase in pediatric firearm injuries during the COVID-19 pandemic impacted youth in all but the lowest deprivation quartile. Efforts at curbing gun violence should identify and amplify protective effects in under-resourced communities.

Contextual Factors Influencing Firearm Deaths Occurring Among Children

OBJECTIVES

Contextual factors that contribute to firearm injuries among children aged 0 to 10 are not well understood.

METHODS

A retrospective review of the National Fatality Review-Case Reporting System was conducted for firearm deaths of children aged 0 to 10 from 2004 to 2020. Descriptive analyses characterized child and parent demographics, incident details, firearm characteristics, and firearm use. Cluster analysis identified key clustering of contextual variables to inform prevention efforts.

RESULTS

Within the study timeframe, 1167 child firearm deaths were reported (Mage = 4.9; 63.2% male; 39.4% urban). At the time of the incident, 52.4% of firearms were reported unlocked and 38.5% loaded. Firearm deaths occurred primarily at the child's home (69.0%) or a friend or relative's home (15.9%), with most involving a handgun (80.6%). Children were supervised in 74.6% of incidents, and 38.4% of child supervisors were impaired during the incident. Cluster analysis identified incident contextual factors clustering in distinct groups, including unsupervised firearm play, long gun discharge while cleaning, hunting, or target shooting, supervised discharge within the child's home, murder-suicide events, deaths occurring in the context of intimate partner violence, and community violence firearm deaths.

CONCLUSIONS

Data highlight the importance of primary prevention through secure firearm storage to prevent child firearm deaths. Efforts focused on identifying and reducing intimate partner violence, addressing community violence (eg, community greening), and implementing policy that limit firearm access (eg, domestic violence restraining orders, background checks), may reduce child firearm deaths.

Pediatric Firearm Reinjury: A Retrospective Statewide Risk Factor Analysis

INTRODUCTION

Pediatric firearm injuries are a significant public health concern in the United States. This study examines risk factors for firearm reinjury in Maryland's pediatric population.

METHODS

Pediatric patients (age 0-19 y) who presented to any hospital in Maryland with a firearm injury between October 1, 2015, and December 31, 2019, were identified in the Maryland Health Services Cost Review Commission database and were followed for repeat firearm injuries through March 31, 2020. Logistic regression was used to analyze risk factors for reinjury. Geospatial analysis was used to identify communities with the highest prevalence of reinjury.

RESULTS

Of 1351 index presentations for firearm injuries, 102 (7.3%) were fatal. Among children with nonfatal injuries, 40 (3.1%) re-presented with a second firearm injury, 25% of which were fatal. The median interval to reinjury was 149 d [interquartile range: 73-617]. Reinjury was more common in children aged ≥15 y (90% versus 76%), males (100% versus 87%), of Black race (90% versus 69%) or publicly insured (90% versus 68%) (all P < 0.05). Most lived in highly deprived neighborhoods of Baltimore City. No single factor was significant in multivariable models.

CONCLUSIONS

Pediatric firearm reinjury is rare but highly morbid in Maryland. While prior studies have shown Black race to be independently associated with firearm reinjury, we found the effect of race was entirely attenuated after controlling for neighborhood deprivation. These findings underscore the urgent need for targeted interventions in areas identified as high risk in addition to policies to reduce youth firearm access.

Gun violence revictimization in New York State: What increases the risk of being shot again?

BACKGROUND

While gun injuries are more likely to occur in urban settings and affect people of color, factors associated with gun violence revictimization-suffering multiple incidents of gun violence-are unknown. We examined victim demographics and environmental factors associated with gun violence revictimization in New York State (NYS).

METHODS

The 2005 to 2020 NYS hospital discharge database was queried for patients aged 12 years to 65 years with firearm-related hospital encounters. Patient and environmental variables were extracted. Patient home zip code was used to determine the Social Deprivation Index (SDI) for each patient's area of residence. We conducted bivariate and multivariate analyses among patients who suffered a single incident of gun violence or gun violence revictimization.

RESULTS

We identified 38,974 gun violence victims among whom 2,243 (5.8%) suffered revictimization. The proportion of revictimization rose from 4% in 2008 to 8% in 2020 ( p < 0.01). The median [interquartile range] time from first to second incident among those who suffered revictimization was 359 days [81-1,167 days]. Revictimization was more common among Blacks (75.0% vs. 65.1%, p < 0.01), patients with Medicaid (54.9% vs. 43.2%, p < 0.01), and in areas of higher deprivation (84.8 percentile vs. 82.1 percentile, p < 0.01).

CONCLUSION

Gun violence revictimization is on the rise. People of color and those residing in areas with high social deprivation are more likely to be re-injured. Our findings emphasize the importance of community-level over individual-level interventions for prevention of gun violence revictimization.

Firearm Injuries in Young Children: Surgical Resource Utilization and Implications for Prevention

INTRODUCTION

Pediatric firearm injury prevention research in younger age groups is limited. This study evaluated a large multicenter cohort of younger children with firearm injuries, focusing on injury patterns and surgical resource utilization.

METHODS

Children ≤15 y old sustaining firearm injuries between 2016 and 2021 and treated at 10 pediatric trauma centers in Florida were included. Individual cases were reviewed for demographics, shooting details, injury patterns, resource utilization, and outcomes. Patients were grouped by age into preschool (0-5 y), elementary school (6-10 y), middle school (11-13 y), and early high school (14-15 y). Multivariable logistic regression was used to identify predictors of death and critical resource utilization.

RESULTS

A total of 489 children (80 preschool, 76 elementary school, 92 middle school, and 241 early high school) met inclusion criteria. Demographics, injury patterns, and resource utilization were similar across age groups. Assault and self-harm increased with age. Self-harm was implicated in 5% of cases but accounted for 18% of deaths. Hand surgery (i.e., below-elbow) procedures were common at 8%. Overall mortality was 10%, but markedly higher for self-harm injuries (47%). On multivariable regression, age and demographics were not predictive of death or critical resource utilization, but self-harm intent was a strong independent risk factor for both.

CONCLUSIONS

This study suggests that given the age distribution and disproportionately high impact of self-harm injuries, behavioral health resources should be available to children at the middle school level or earlier. Hand surgery may represent an overlooked but frequently utilized resource to mitigate injury impact and optimize long-term function.

The association between childhood opportunity index and pediatric hospitalization for firearm injury or motor vehicle crash

BACKGROUND

Community-level factors can profoundly impact children's health, including the risk of violent injury. This study's objective was to understand the relationship between the Childhood Opportunity Index and pediatric firearm injury owing to interpersonal violence compared with a motor vehicle crash.

METHODS

All pediatric patients (<18 years) who presented with an initial encounter with a firearm injury or motor vehicle crash between 2016 to 2021 were identified from 35 children's hospitals included in the Pediatric Health Information System database. The child-specific community-level vulnerability was determined by the Childhood Opportunity Index, a composite score of neighborhood opportunity level data specific to pediatric populations.

RESULTS

We identified 67,407 patients treated for injuries related to motor vehicle crashes (n = 61,527) or firearms (n = 5,880). The overall cohort had a mean age of 9.3 (standard deviation 5.4) years; 50.0% were male patients, 44.0% non-Hispanic Black, and were 60.8% publicly insured. Compared with motor vehicle crash injuries, patients with firearm-related injuries were older (12.2 vs 9.0 years), more likely to be male patients (77.7% vs 47.4%), non-Hispanic Black (63.5% vs 42.1%), and had public insurance (76.4 vs 59.3%; all P < .001). In multivariable analysis, children living in communities with lower Childhood Opportunity Index levels were more likely to present with firearm injury than those living in communities with a very high Childhood Opportunity Index. The odds increased as the Childhood Opportunity Index level decreased (odds ratio 1.33, 1.60, 1.73, 2.00 for high, moderate, low, and very low Childhood Opportunity Index, respectively; all P ≤ .001).

CONCLUSION

Children from lower-Childhood Opportunity Index communities are disproportionately impacted by firearm violence, and these findings have important implications for both clinical care and public health policy.

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

BACKGROUND

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.

METHODS

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.

RESULTS

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.

CONCLUSION

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.

Socioeconomic Factors and Pediatric Injury

Purpose of Review

The goal of this review is to describe how socioeconomic status (SES) is evaluated in the pediatric trauma literature and further consider how differences in SES can lead to inequities in pediatric injury.

Recent Findings

Insurance status, area-level income, and indices of socioeconomic deprivation are the most common assessments of socioeconomic status. Children from socioeconomically disadvantaged backgrounds experience higher rates of firearm-related injuries, motor vehicle-related injuries, and violence-related injuries, contributing to inequities in morbidity and mortality after pediatric injury. Differences in SES may also lead to inequities in post-injury care and recovery, with higher rates of readmission, recidivism, and PTSD for children from socioeconomically disadvantaged backgrounds.

Summary

Additional research looking at family-level measures of SES and more granular measures of neighborhood deprivation are needed. SES can serve as an upstream target for interventions to reduce pediatric injury and narrow the equity gap.
