Widespread, bipartisan aversion exists to neighbors owning AR-15s or storing guns insecurely.

Over 45,000 gun deaths occur annually in the United States, a country with more than 100 million gun owners and more than 350 million guns. Nevertheless, passing legislation to reduce gun violence is difficult because the issue is intensely polarized. Polls asking about general gun policies (e.g., AR-15 restrictions) demonstrate that, at least in the abstract, Americans disagree vehemently about whether civilians should be able to keep and bear arms. It is possible, however, that a hidden consensus exists in America, which has thus far escaped attention-specifically, that when the focus is on their immediate environments and daily lives, even traditionally pro-gun groups may exhibit aversion to certain types of gun ownership and storage practices. To test this, we conducted two preregistered survey experiments with a large national sample. The first was a conjoint analysis where respondents chose between neighbors (n = 33,596 choices) who randomly varied on seven attributes, including gun ownership (none, pistol, AR-15). No group of respondents, not even traditionally pro-gun groups (e.g., Republicans), exhibited a significant preference for living near gun owners, and every group was averse to AR-15-owning neighbors. The second experiment, per debates about safe-storage laws, was a picture-based factorial vignette that randomized a neighbor's gun storage practices (n = 2,098). Every group of respondents was averse to interacting with a neighbor who stored guns outside of a locked safe. Our findings demonstrate that there is widespread agreement that certain types of gun ownership and storage practices are undesirable for communities.

Evaluating the impact of a street outreach intervention on participant involvement in gun violence.

The past several years have witnessed increased calls for community violence interventions (CVIs) that address firearm violence while centering local expertise and avoiding the criminal legal system. Currently, little evidence exists on CVI effectiveness at the individual level. This study presents an evaluation of the impact of a street outreach-based CVI [Chicago CRED (Create Real Economic Destiny)] on participant involvement in violence. We used a quasiexperimental design with a treatment sample of 324 men recruited by outreach staff from 2016 to 2021 and a balanced comparison sample of 2,500 men from a network of individuals arrested in CRED's service areas. We conducted a Bayesian survival analysis to evaluate CRED's effect on individual violence-related outcomes on three levels of treatment: All enrolled participants, a subsample that made it through the initial phase, and those who completed programming. The intervention had a strong favorable effect on the probability of arrest for a violent crime for those completing the program: After 24 mo, CRED alumni experienced an 11.3 percentage point increase in survival rates of arrest for a violent crime relative to their comparisons (or, stated differently, a 73.4% reduction in violent crime arrests). The other two treatment levels experienced nontrivial declines in arrests but did not reach statistical significance. No statistically significant reduction in victimization risk was detected for any of the treatment levels. Results demonstrate that completion of violence intervention programming reduces the likelihood of criminal legal involvement for participants, despite the numerous systemic and environmental factors that impede personal success.

The State of Firearm Policy Research in the United States.

Firearm-related deaths lead to the most person-years of life lost in the US. There were 48,830 deaths from homicides and suicides in 2021 alone. Firearm access remains at an all-time high in most states - indicated by record manufacturing, sales, employment in firearm industry, taxes collected from sales, and the number of federal background check applications in 2020 and 2021. Yet, firearm injury is a politically contentious topic to the point of stalling progress on an important public health topic. This politicization led to nearly three decades of federal disinvestment in firearm research; reduced surveillance of firearm-related crime, injury, and death; and degraded data quality. This left generations of researchers with limited epidemiologic tools to conduct firearm policy research, jeopardizing the amount and quality of research conducted. Despite these limitations, research has persisted and promising approaches to reduce firearm morbidity and mortality have been identified. Yet the field has struggled to keep pace with methodological advancements and conceptualizations of racial and ethnic disparities as products of systemic racism. In this commentary, we highlight some existing evidence-informed policies, explicate some limitations in the field, and identify opportunities to address the limitations of prior work to strengthen future capacity for evidence-informed prevention.

An introduction to bayesian spatial smoothing methods for disease mapping: modeling county firearm suicide mortality rates.

This article introduces bayesian spatial smoothing models for disease mapping-a specific application of small area estimation where the full universe of data is known-to a wider audience of public health professionals using firearm suicide as a motivating example. Besag, York, and Mollié (BYM) Poisson spatial and space-time smoothing models were fitted to firearm suicide counts for the years 2014-2018. County raw death rates in 2018 ranged from 0 to 24.81 deaths per 10 000 people. However, the highest mortality rate was highly unstable, based on only 2 deaths in a population of approximately 800, and 80.5% of contiguous US counties experienced fewer than 10 firearm suicide deaths and were thus suppressed. Spatially smoothed county firearm suicide mortality estimates ranged from 0.06 to 4.05 deaths per 10 000 people and could be reported for all counties. The space-time smoothing model produced similar estimates with narrower credible intervals as it allowed counties to gain precision from adjacent neighbors and their own counts in adjacent years. bayesian spatial smoothing methods are a useful tool for evaluating spatial health disparities in small geographies where small numbers can result in highly variable rate estimates, and new estimation techniques in R software have made fitting these models more accessible to researchers.

Estimating Community Disruption from Nighttime Gunshots in 6 U.S. Cities, 2015 to 2021.

BACKGROUND: Gunshots affect those directly involved in an incident and those in the surrounding community. The community-level impact of nighttime gunshots, which may be particularly disruptive to the sleep of nearby community members, is unknown. OBJECTIVE: Our aim is to estimate the number of people potentially affected by nighttime gunshots and the relationship between nighttime gunshots and median household income in the USA. DESIGN: We collected publicly available data on the timing and location of gunshots in six U.S. cities (Baltimore, MD; Boston, MA; Washington, D.C.; New York, NY; Philadelphia, PA; and Portland, OR) from 2015 to 2021. We then analyzed the data by computing rate ratios (RRs) to compare the frequency of gunshots during nighttime hours (6:00 pm to 5:59 am) versus daytime hours (6:00 am to 5:59 pm). Additionally, we used geospatial mapping to create choropleth maps to visualize the variation in nighttime gunshot density across cities. We estimated, using city-wide population, person-nights potentially impacted by the sound of gunshots within areas of 0.2- (low) and 0.5-mile (high) radius. Finally, for five of six cities where data on median household income were available by census tract, we built nonlinear regression models to estimate the relationship between the number of nighttime gunshots and median household income. KEY RESULTS: We analyzed 72,236 gunshots. Gunshots were more common during the nighttime than daytime (overall RR = 2.5). Analyses demonstrated that the low estimates for the mean annual number of person-nights impacted by nighttime gunshots were 0.4 million in Baltimore and Portland, 1.3 million in Philadelphia, 1.6 million in Boston, 2.9 million in New York City, and 5.9 million in Washington. The number of nighttime gunshots was inversely related to median household income. CONCLUSIONS: Nighttime gunshots are prevalent, particularly in low-income neighborhoods, and may have under-recognized effects on the surrounding community.

Firearm Ownership: A Key Factor to Consider in Firearm Suicide Deaths in Children, Despite State Gun Laws.

INTRODUCTION: Firearm-related suicides among children present a significant public health concern and a tragic loss of young lives. This study explores the relationship between firearm-related suicides, gun ownership, and state-specific gun laws. METHODS: This retrospective cohort study collected data from the Centers for Disease Control and Prevention Wide-Ranging Online Data for Epidemiologic Research on children under 18 who died by firearm-related suicides between 2009 and 2016 in all 50 states and D.C. It also utilized data from the RAND State-Level Estimates of Household Firearm Ownership. The study focused on the rate of child firearm suicide deaths per 100,000 individuals. The key variable of interest was the percentage of guns owned per household in each state. Univariable analysis was conducted to examine the association between individual gun laws and child firearm suicide mortalities, while multivariable regression, adjusting for household gun ownership and significant firearm legislation, was employed to assess connection to child firearm suicide mortality. RESULTS: From 2009 to 2016, 3903 children died from firearm-related suicides in the United States. In our analysis, 15 out of 44 firearm laws were found to be associated with reducing the rates of firearm suicides among children (P < 0.05). However, multivariable regression showed that higher state gun ownership rates were the primary predictor of increased child fatalities from firearms, with children in such states being 325% more likely to die when analyzing handgun laws and 337% more likely when analyzing long gun laws, as indicated by coefficients of 4.25 and 4.37, respectively. No state laws alone notably improved death rates. CONCLUSIONS: Gun ownership has a stronger association with child suicide rates than state-specific gun laws. Given the weight of gun ownership, future research should prioritize comprehensive public health initiatives to prevent child firearm-related suicides.

Pooled Analysis of Trauma Centers Better Predicts Risk Factors for Firearm Violence Reinjury.

INTRODUCTION: Many trauma centers use the first firearm injury admission as a reachable moment to mitigate reinjury. Understanding repeat firearm violence can be difficult in metropolitan areas with multiple trauma centers and laws that prohibit sharing private health information across health systems. We hypothesized that risk factors for repeat firearm violence could be better understood using pooled data from two major metropolitan trauma centers. METHODS: Two level I trauma center registries were queried (2007-2017) for firearm injury admissions using International Classification of Diseases, Ninth and Tenth Revision (ICD9/10) Ecodes. A pseudo encryption tool allowed sharing of deidentified firearm injury and repeat firearm injury data without disclosing private health information. Factors associated with firearm reinjury admissions including, age, sex, race, payor, injury severity, intent, and discharge, were assessed by multivariable logistic regression. RESULTS: We identified 2145 patients with firearm injury admissions, 89 of whom had a subsequent repeat firearm injury admission. Majority of repeat firearm admissions were assaulted (91%), male (97.8%), and non-Hispanic Black (86.5%). 31.5% of repeat firearm injury admissions were admitted to a different trauma center from their initial admission. Independent predictors of repeat firearm injuries were age (adjusted odds ratio [aOR] 0.94, P < 0.001), male sex (aOR 6.18, P = 0.013), non-Hispanic Black race (aOR 5.14, P = 0.007), or discharge against medical advice (aOR 6.64, P=<0.001). CONCLUSIONS: Nearly a third of repeat firearm injury admissions would have been missed in the current study without pooled metropolitan trauma center data. The incidence of repeat firearm violence is increasing and those at the highest risk for reinjury need to be targeted for mitigating interventions.

A Decade of Firearm Injuries: Children Caught in the Crossfire.

INTRODUCTION: Firearm injuries (FIs) are the leading cause of preventable morbidity and mortality in pediatric patients. In this study, we aim to define evolving trends and avenues for prevention. METHODS: Following institutional review board approval, medical records of patients presenting to our two State-Designated Level 1 Pediatric Trauma Centers for treatment of FIs from 2010 to 2019 were retrospectively reviewed. Data was analyzed with Chi-Squared and Student's t-test; P-value <0.05 was significant. RESULTS: 1037 FI encounters from 1005 unique patients aged 0-21 y were included. 70.4% (n = 730) were determined to be assaults, 26.1% (n = 271) unintentional, and 1.7% (n = 18) self-inflicted injuries. Overall mortality was 4.5% (n = 45). FI victims were most commonly African American (n = 836, 80.6%), male (n = 869, 83.8%), aged 13-17 (n = 753, 72.6%), and from single-parent families (n = 647, 62.4%). The incidence of FIs increased significantly over the last 5 y of the study (2010-2014, 6.8 FIs/month), compared to 2015-2019 (averaging 10.6 FIs/month, P < 0.0001). Concurrently, FI related fatality increased from an average of 2.6 deaths/year (2010-2014) to 6.4 deaths/year (2015-2019, P = 0.064). Results were subanalyzed for pediatric patients aged 0-14 y. For the entire cohort, 12.1% (n = 116) recidivists were identified. Geographic patterns of injury were identified, with 75% of all FIs clustered in a single urban region. CONCLUSIONS: Incidence of pediatric FIs is increasing in recent years, with high mortality rates. Violence and recidivism are geographically concentrated, offering an opportunity for targeted interventions.

Pediatric Homicides: Not Just a Teenage Problem.

INTRODUCTION: Homicide is a leading cause of death for American children. We hypothesized demographics and homicide circumstances would differ by victim age. METHODS: We performed a retrospective analysis of the 2003-2020 National Violent Death Reporting System. The National Violent Death Reporting System collects data from nearly all 50 states, the District of Columbia, and Puerto Rico. Demographics (age, sex, race, and ethnicity), homicide year, and weapon type were abstracted. Inclusion criteria were pediatric victims (age < 18). Two groups: 0-4 y old (young cohort [YC]) and 13-17 y old (teen cohort [TC]) were compared. Chi-squared tests, p-test, and t-tests with significance P < 0.05 were used to determine the association between victim demographics, cohort, and homicide mechanism. RESULTS: 10,569 pediatric (male: 70.2% [n = 7424], median age: 12 y old [interquartile range 1-16], black: 52.7% [n = 5573]) homicides met inclusion. Homicides demonstrated a bimodal age distribution (YC: 40.9% [n = 4320] versus TC: 48.9% [n = 5164]). Gender and race were both associated with homicide victimhood (P < 0.001). TC homicides were more likely to be male (YC: 57.8% [n = 2496] versus TC: 83.7% [n = 4320], P < 0.001) and black (YC: 40.1% [n = 1730] versus TC: 65.0% [n = 3357], P < 0.001). Pediatric homicides increased from 2018 (n = 1049) to 2020 (n = 1597), with only TC demonstrating a significant increase (2018: n = 522 versus 2020: n = 971, P < 0.001). Homicide mechanism was significantly associated with age (Blunt: YC: 57.5% [n = 2484] versus TC: 2.9% [n = 148], P < 0.001; Penetrating: YC: 7.9% [n = 340] versus TC: 92.8% [n = 4794], P < 0.001). CONCLUSIONS: Pediatric homicides demonstrate distinct demographic characteristics and homicide mechanisms between two at risk age cohorts. Age-based education and intervention strategies may increase injury prevention programs' efficacy.

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.

Firearm Injuries Are on the Rise, the Results of a Pediatric Trauma Center.

INTRODUCTION: Firearm injury is the leading cause of death in children. The recent rise has coincided with the COVID-19 pandemic. The purpose of this study was to evaluate the trends of pediatric firearm injury over a 6-y period, to include the COVID-19 pandemic, at our pediatric trauma center. METHODS: A retrospective review of the trauma registry at a free-standing children's hospital from January 2018 to December 2023 was performed. The variables evaluated included year of injury, age of injury, race, gender, admission requirements, need for blood products, need for operation, mortality, insurance type, and reason for injury. RESULTS: There were 397 firearm injury presentations identified over the 6-y period. The median age of injury was 13 y with an interquartile range of 6-15 y. Most were male (72.3%) and of Black race (74.6%). A majority of children who sustained a firearm injury had Medicaid (77.8%). During the years of 2018 and 2019, we evaluated 40 and 39 patients, respectively. Over the next 2 y, there was a dramatic increase in pediatric firearm injuries with an increase of 65% (N = 66) in 2020 and 102.5% (N = 81) in 2021. Although there was less of an increase above baseline in 2022, there was still an elevation of 82.5% (N = 73). By the end of 2023, there had been a 145% rise (N = 98) in pediatric firearm injuries above the baseline year of 2018. The mortality rate was 7.6% (N = 30), which is 2.5 times higher than the all-cause trauma mortality of 3.1% at our facility. CONCLUSIONS: The number of firearm injuries dramatically increased during the COVID-19 pandemic and these increases have been sustained. Most of the victims have been male, of Black race, and publicly insured. While the state population of Alabama is 26.4% Black race, Black children account for 74.6% of all firearm-injured pediatric patients in our trauma registry. The reason for this disparity is not well-understood. Through ongoing research, we hope to gain insight into the reasons behind pediatric firearm injury and the best ways to mitigate them through both the medical and public health arenas.

The Initial Experience After Pediatric Firearm Injury: A Multifaceted Qualitative Approach.

INTRODUCTION: Firearm victims sustain a disproportionate mental health burden. Inpatient pediatric psychology consult liaison (CL) services provide comprehensive evaluation after injury. We aim to explore CL documentation qualitatively to better understand the initial psychological experience after firearm injury in children compared to motor vehicle crash (MVC) injury. We hypothesized that meaningful differences between the cohorts would be evident by thematic, sentiment, and word cloud analyses of CL notes. MATERIALS AND METHODS: This single-institution, retrospective study at a level I pediatric trauma center identified 5-17-y-old children who sustained firearm injuries and were admitted for ≥48 h from January 1, 2016 to March 31, 2021. Firearm-injured children were propensity score-matched to MVC-injured children. Thematic, sentiment, and word cloud analyses were completed for all CL notes. RESULTS: 98 firearm-injured children were identified. The CL service evaluated 71% of firearm-injured children and 65% of MVC-injured children. Domains of resources, encountering the medical system, prior psychological and legal influences, immediate cognitive reactions, and social influences were identified based on extracted themes. Sentiment analysis revealed more negative than positive words for both firearm- (3318 versus 2190 words) and MVC-injured children (2225 versus 1994 words). Word cloud showed that firearm-injured child notes more frequently mentioned "trauma", while MVC-injured child notes more frequently mentioned "family" and "support". CONCLUSIONS: The pediatric CL note analysis suggests that the experience after firearm injury differs from that after MVC injury in reference to family and support. CL notes covered a breadth of topics beyond the psychological impact alone. Understanding the experiences of injured children in relation to injury mechanism offers opportunity for focused intervention strategies.

Firearm-Related Juvenile Death Rates Correlate With Gun Ownership Rates, Measures of Guns in Circulation, and Leniency of Existing Firearm Laws Among U.S. States.

INTRODUCTION: Firearms now represent the leading cause of death in U.S. children. Therefore, this study aimed to determine if state-level rates of gun ownership, guns in circulation, and strictness of firearm-related laws are related to firearm-related mortality among both juveniles and overall populations. MATERIALS AND METHODS: State firearm mortality rates among the juvenile and overall populations were obtained from 2010 to 2020. The number of weapons registered with the Bureau of Alcohol, Tobacco, Firearms, and Explosives (ATF) and federal firearms licensees for each state were also recorded. Giffords Law Center Scorecard Rankings, a relative measure of the restrictiveness of each state's gun laws, were also collected. Unadjusted linear regressions modeled the relationships between firearm-associated mortality and ATF-registered weapons, federal firearm licensees, Giffords Center rankings, and gun ownership rates. Multivariable (adjusted) analyses were performed to control for poverty, unemployment, and poor mental health. RESULTS: Unadjusted analyses demonstrated that higher gun ownership rates and more lenient gun laws were associated with increased firearm-associated mortality among juveniles. Similarly, these measures as well as increased ATF-registered weapons and ATF federal firearm licensees were associated with increased firearm mortality in the overall population. In the adjusted analyses, more ATF-registered weapons, more ATF federal firearm licensees, higher gun ownership rates, and more lenient firearm laws were associated with increased firearm-related mortality in the overall population, while increased gun ownership and higher Giffords Center rankings were associated with increased firearm-associated mortality in the pediatric population. CONCLUSIONS: To reduce the toll of gun violence in the United States, policymakers should focus on implementing more restrictive firearm laws and reducing the prevalence of guns in their communities.

Nearly 20 Years Since the Federal Ban: Can State-Level Assault Weapon Prohibitions Fill the Void? Comparative Analysis of Case Fatality and Assault Weapon Recovery in States With and Without an Assault Weapon Ban.

INTRODUCTION: Few states established assault weapon bans (AWBs) after the federal AWB expired. The effectiveness of state AWBs as well as neighboring state legislation, in reducing the local prevalence of assault weapons (AWs) or in reducing overall shooting lethality is unknown. METHODS: We queried the Gun Violence Archive (2014-2021) to identify US firearm injuries and fatalities. Shooting case fatality rates were compared among states with and without AWBs, as reported in the State Firearm Laws Database. Data on recovered firearms was obtained from the ATF Firearms Trace Database and used to estimate weapon prevalence. Recovered firearms were classified as AWs based on caliber (7.62 mm, 5.56 mm, 0.223 cal). We performed spatially weighted linear regression models, with fixed effects for state and year to assess the association between geographically clustered state legislation and firearm outcomes. RESULTS: From 2014 to 2021, the US shooting victim case fatality rate was 8.06% and did not differ among states with and without AWBs. The proportion of AWs to total firearms was 5.0% in states without an AWB and 6.0% in states with an AWB (mean difference [95% CI] = -0.8% [-1.6% to -0.2%], P = 0.03). Most recovered firearms in AWB states originated from non-AWB states. On adjusted models, there was no association between state-level AWB and firearm case fatality; however, adjacency to states with an AWB was associated with lower case fatality (P < 0.001). Clustered AWB states with shared borders had lower AW prevalence and fatality rates than the rest of the US. CONCLUSIONS: Isolated state AWBs are not inversely associated with shooting case fatality rates nor the prevalence of AWs, but AWBs among multiple neighboring states may be associated with both outcomes.

Geospatial Analysis of Social Vulnerability, Race, and Firearm Violence in Chicago.

INTRODUCTION: Urban firearm violence (UFV) is associated with inequities rooted in structural racism and socioeconomic disparities. Social vulnerability index (SVI) is a composite measure that encompasses both. We sought to understand the relationship between SVI and the incidence of UFV in Chicago using geospatial analysis for the first time. MATERIALS AND METHODS: Firearm assaults in Chicago 2001-2019 were obtained from the Trace. Locations of incidents were geocoded using ArcGIS and overlaid with census tract vector files. These data were linked to 2018 SVI measures obtained from the Center for Disease Control and Prevention. Shooting rates were calculated by tabulating the total number of shootings per capita in each census tract. We used Poisson regression with robust error variance to estimate the incident rate of UFV in different levels of social vulnerability and Local Moran's I to evaluate spatial autocorrelation. RESULTS: In total, 642 census tracts were analyzed. The median shooting rate was 2.6 per 1000 people (interquartile 0.77, 7.0). When compared to those census tracts with very low SVI, census tracts with low SVI had a 1.7-time increased incident rate of shootings (incidence rate ratio [IRR] 1.74, 95% CI 1.08, 2.81), tracts with moderate SVI had a 3.1-time increased incident rate (IRR 3.07, 95% CI 2.31, 4.10), and tracts with high SVI had a 7-time increased incident rate (IRR 7.03, 95% CI 5.45, 9.07). CONCLUSIONS: In Chicago, social vulnerability has a significant association with rates of firearm violence, providing a focus point for policy intervention to address high rates of interpersonal violence in similar cities.

Colleges and Crime-Comparing Homicide and Suicide Rates Among College Towns and Their Counterparts.

INTRODUCTION: To investigate differences in homicide and suicide rates across college town status and determine whether college towns were predisposed to changes in rates over time. METHODS: We analyzed county-level homicide and suicide rates (total and by firearm) across college town status using 2015-2019 CDC death certificate data and data from the American Communities Project. RESULTS: Population-level homicide rates were similar across college town status, but younger age groups were at increased risk for firearm homicide and total homicide in college towns. College town status was associated with lower population-level firearm suicide rates, but individuals aged less than 18 y were at increased risk for total and firearm suicide. Finally, college towns were not classified as outliers for changes in either firearm homicide or suicide rates over time. CONCLUSIONS: College towns had similar homicide rates and significantly lower firearm suicide rates than other counties; however, individuals aged less than 18 y were at increased risk for both outcomes. The distinctive demographic, social, economic, and cultural features of college towns may contribute to differing risk profiles among certain age groups, thus may also be amenable to focused prevention efforts.

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.

Firearm-Related Injuries and the US Opioid and Other Substance Use Epidemic: A Nationwide Evaluation of Emergency Department Encounters.

INTRODUCTION: There has been a sharp climb in the Unites States' death rate among opioid and other substance abuse patients, as well as an increased prevalence in gun violence. We aimed to investigate the association between substance abuse and gun violence in a national sample of patients presenting to US emergency departments (EDs). METHODS: We queried the 2018-2019 Nationwide Emergency Department Sample for patients ≥18 years with substance abuse disorders (opioid and other) using International Classification of Diseases, 10th Revision, Clinical Modification codes. Within this sample, we analyzed characteristics and outcomes of patients with firearm-related injuries. The primary outcome was mortality; secondary outcomes were ED charges and length of stay. RESULTS: Among the 25.2 million substance use disorder (SUD) patients in our analysis, 35,306 (0.14%) had a firearm-related diagnosis. Compared to other SUD patients, firearm-SUD patients were younger (33.3 versus 44.7 years, P < 0.001), primarily male (88.6% versus 54.2%, P < 0.001), of lower-income status (0-25th percentile income: 56.4% versus 40.5%, P < 0.001), and more likely to be insured by Medicaid or self-pay (71.6% versus 53.2%, P < 0.001). Firearm-SUD patients had higher mortality (1.4% versus 0.4%, P < 0.001), longer lengths of stay (6.5 versus 4.9 days, P < 0.001), and higher ED charges ($9269 versus $5,164, P < 0.001). Firearm-SUD patients had a 60.3% rate of psychiatric diagnoses. Firearm-SUD patients had 5.5 times greater odds of mortality in adjusted analyses (adjusted odds ratio: 5.5, P < 0.001). CONCLUSIONS: Opioid-substance abuse patients with firearm injuries have higher mortality rates and costs among these groups, with limited discharge to postacute care resources. All these factors together point to the urgent need for improved screening and treatment for this vulnerable group of patients.

Nationwide Analysis of Firearm Injury Versus Other Penetrating Trauma: It's Not All the Same Caliber.

INTRODUCTION: Ballistic injuries cause both a temporary and permanent cavitation event, making them far more destructive and complex than other penetrating trauma. We hypothesized that global injury scoring and physiologic parameters would fail to capture the lethality of gunshot wounds (GSW) compared to other penetrating mechanisms. METHODS: The 2019 American College of Surgeons Trauma Quality Programs participant use file was queried for the mortality rate for GSW and other penetrating mechanisms. A binomial logistic regression model ascertained the effects of sex, age, hypotension, tachycardia, mechanism, Glasgow Coma Scale, ISS, and volume of blood transfusion on the likelihood of mortality. Subgroup analyses examined isolated injuries by body regions. RESULTS: Among 95,458 cases (82% male), GSW comprised 46.4% of penetrating traumas. GSW was associated with longer hospital length of stay (4 [2-9] versus 3 [2-5] days), longer intensive care unit length of stay (3 [2-6] versus 2 [2-4] days), and more ventilator days (2 [1-4] versus 2 [1-3]) compared to stab wounds, all P < 0.001. The model determined that GSW was linked to increased odds of mortality compared to stab wounds (odds ratio 4.19, 95% confidence interval 3.55-4.93). GSW was an independent risk factor for acute kidney injury, acute respiratory distress syndrome, venous thromboembolism, sepsis, and surgical site infection. CONCLUSIONS: Injury scoring systems based on anatomical or physiological derangements fail to capture the lethality of GSW compared to other mechanisms of penetrating injury. Adjustments in risk stratification and reporting are necessary to reflect the proportion of GSW seen at each trauma center. Improved classification may help providers develop quality processes of care. This information may also help shape public discourse on this highly lethal mechanism.

Identifying overlaps and disconnects between media reports and official records of nonfatal firearm injuries in Indianapolis, Indiana, 2021-2022.

OBJECTIVE: Open-source data systems, largely drawn from media sources, are commonly used by scholars due to the lack of a comprehensive national data system. It is unclear if these data provide an accurate and complete representation of firearm injuries and their context. The study objectives were to compare firearm injuries in official police records with media reports to better identify the characteristics associated with media reporting. METHODS: Firearm injuries were identified in open-source media reports and compared to nonfatal firearm injury (n = 1642) data from official police records between January 1, 2021 to December 31, 2022 in Indianapolis, Indiana. Events were matched on date, location, and event circumstances. Four multivariate, multi-level mixed effects logistic regression models were conducted to assess which survivor, event, and community characteristics were associated with media reporting. Data were analyzed 2023 - January 2024. RESULTS: Media reported 41% of nonfatal shootings in 2021 and 45% in 2022(p < 0.05), which is approximately two out of every five shootings. Shootings involving multiple survivors, children, and self-defense were more likely to be reported, whereas unintentional shootings and shootings that occurred in structurally disadvantaged communities were less likely to be reported. CONCLUSIONS: Findings suggest that relying on media reports of firearm injuries alone may misrepresent the numbers and contexts of shootings. Public health interventions that educate journalists about these important issues may be an impactful firearm violence prevention strategy. Also, it is critical to link data systems at the local level to ensure interventions are designed and evaluated using accurate data.
