UNASSIGNED: The rate of worldwide mass shootings increased almost 400% over the last 40 years. About 30% are followed by the perpetrator\'s fatal or nonfatal suicide attempt.
UNASSIGNED: We examined the rate of fatal and nonfatal attempts among 528 mass shooters over the last 40 years and their relationship to detected mental illness to better understand this specific context of suicide. We collected information on U.S.-based, personal-cause mass murders that involved one or more firearms, from online sources.
UNASSIGNED: A greater proportion of mass shooters from 2000 to 2019 took or attempted to take their own lives (40.5%) compared with those from 1980 to 1999 (23.2%, p < 0.001). More than double the proportion of perpetrators who made a fatal or nonfatal suicide attempt had a history of non-psychotic psychiatric/neurologic symptoms (38.9%), compared with perpetrators who did not make a fatal or nonfatal suicide attempt (18.1%; p < 0.001). Among mass shooters who made fatal or nonfatal suicide attempts, 77 of 175 (44%) did not have any recorded psychiatric, neurologic, or substance use condition. Of the 98 mass shooters who made fatal or non-fatal suicide attempts and had a psychiatric, substance use, or neurologic condition, 41 had depressive disorders.
UNASSIGNED: It is possible that a lack of information about the perpetrators\' mental health or suicidal ideation led to an underestimation of their prevalence. These data suggest that suicide associated with mass shootings may represent a specific context for suicide, and approaches such as psychological autopsy can help to ascertain when psychiatric illness mediates the relationship between mass shootings and suicide.
We examined 528 mass shootings.A greater proportion of mass shooters from 2000-2019 made a fatal or nonfatal suicide attempt (123/304, 40.5%) compared with mass shooters from 1980-1999 (52/224, 23.2%), χ2 = 17.3, p<.001.More than double the proportion of perpetrators who made a fatal or nonfatal suicide attempt had a history of non-psychotic psychiatric/neurologic symptoms (38.9%), compared with those who did not (18.1%; p < 0.001).Among mass shooters who made a fatal or nonfatal suicide attempt, 77 of 175 (44%) did not have any recorded psychiatric, neurologic, or substance use condition. However, it is possible that a lack of information about the perpetrators’ mental health or suicidal ideation led to an underestimation of their prevalence.These results suggest that perpetrators may have considered suicide a potential outcome of such an event, and/or that the perpetrators’ high levels of aggression and anger, accompanied by an impaired capacity for restraint, resulted in homicide followed by suicidal behavior.Psychological autopsies can clarify the role of psychiatric illness and more extreme aggressive traits in homicide-suicide instances of mass shootings.

Gun violence (GV) and safety is a contentious topic in the United States, despite increasing morbidity and mortality among children and adolescents. It is important for physicians to take a role in preventing future GV. This article aims to present several methods that physicians can use to prevent GV in their own communities, ranging from implementation of large-scale intervention programs to simple screenings and anticipatory guidance. As the problem of GV persists, it is important for physicians to use their role to identify individuals who are at high-risk and advocate for changes that will benefit their future health.

This study examines and describes circumstances involving non-fatal firearm injuries in a pediatric population from a Level I Pediatric Trauma Center in the southeastern U.S. Researchers analyzed Firearm Injury Questionnaire (FIQ) data collected from 144 children and adolescents, aged 2-17 years, who were treated in the emergency department and/or admitted to the hospital for non-fatal firearm injuries. Descriptive statistics are presented regarding participant demographics and FIQ responses, such as caregiver information, mental health history, adverse childhood experience (ACE) exposure, firearm access, injury intent, relationship to shooter, type of firearm used, and context of injury. Most patients identified as Black (82%) and male (75%), with most injuries categorized as intentional (72%) versus unintentional (24%) assaults. The average ACEs score was .60, with only 37% of patients\' reporting any ACE experience; however, nearly half (47%) of patients reported experiencing a traumatic event beyond an identified ACE. Community violence was the most common context that attributed to patients\' assaults (56%). As U.S. pediatric gun injury and fatality trends are increasing, this study provides timely data regarding pediatric firearm injuries and exposure to community violence. These findings highlight the need to provide integrated health services to pediatric patients experiencing non-fatal firearm injuries. Researchers discuss public health implications for integrated mental health care services, hospital- and school-based violence intervention programs, policy recommendations, and directions for future research.

BACKGROUND: Our previous work demonstrated that use of ShotSpotter (SS), a gunfire detection system, and use of police department (PD) transport decreased response and transport time for gunshot wound (GSW) victims versus events with non-ShotSpotter (NSS). The purpose of this study was to evaluate transport trends and how they are linked to SS in the period of 2016-2021 in Camden, NJ.
METHODS: This was a single-center, retrospective observational study. Demographics, response time, transport time, and clinical data were collected. Independent t-test, Mann-Whitney U test, chi-squared test, and linear regression to correct for transport time and method of transport were used to compare outcomes (P < 0.05).
RESULTS: A total of 267 GSWs were included: 77 emergency medical technicians (EMS)-SS, 41 EMS-NSS, 116 PD-SS, and 33 PD-NSS. When comparing response from 2016 to 2021, PD improved from 4 to 2 min (P = 0.001). EMS improved from 6.4 min (EMS-NSS) and 4.5 min (EMS-SS) to 5 min (EMS- NSS) and 4 min (EMS-SS) (P = 0.281). In addition, PD transport times, 5 min (SS) and 4 min (NSS), were faster than EMS, 9 min (SS and NSS) (P < 0.001). Overall PD transport volume increased with a peak in 2020 (68.3%). There was also an increase in PD-NSS transport 4% to 37.9% (P < 0.001). EMS-SS transport decreased from 54.7% to 6.9% (P < 0.001).
CONCLUSIONS: The presence of SS technology in a small urban setting continues to be associated with a higher rate of PD transport of GSW victims. The critical time of dispatch and transport for both PD and EMS has shown durable improvement.

Background: The burden of firearm injury (FI) extends beyond hospitalization; however, literature focuses mostly on short-term physical outcomes. This study aimed to assess changes in patient-reported outcomes following firearm-related trauma. We hypothesized long-term patient-reported socioeconomic, mental health, and quality-of-life (QoL) outcomes are worse post-FI compared to pre-FI.Methods: This was a retrospective study where a phone survey was conducted with FI survivors admitted between January 2017 and August 2022 at a level 1 trauma center. Survey questions assessed demographics, socioeconomics, and mental and physical health pre-FI vs ≥ 6 months post-FI; the McNemar test was used for comparisons. The PROMIS-29 + 2v2.1 NIH validated instrument was used to assess long-term QoL. Standardized NIH PROMIS T-scores were calculated using the HealthMeasures Scoring Service.Results: Of 204 eligible FI survivors, 71 were successfully contacted and 38 surveyed. Respondents were male (86.8%), Black (76%), and aged 18-29 (55.3%), and 68.4% had high school level education. Post-FI, patients were more likely to be unemployed (55.2% vs 13.2%, P < .001) and report increased mental health needs (84.2% vs 21%, P < .001) compared to pre-FI. Most (73.7%) also reported lasting physical disability. Similarly, the PROMIS instrument demonstrated largely worse health-related QoL scores post-FI, particularly high anxiety/fear (T-score 60.2, SE 3.1, CI 54.6-66.3, Table 2), pain resulting in life interference (T-score 60.0, SE 2.3, CI 55.7-63.9), and worse physical function (T-score 42.5, SE 3.0, CI 38.2-46.9).Conclusions: Firearm injury survivors had more unemployment and worse mental health post-FI compared to pre-FI. Firearm injury survivors also reported significantly worse health-related QoL metrics including pain, anxiety, and physical function 6 months following their trauma. These long-term patient-reported outcomes are a framework to build future outpatient resources.Level of Evidence: IV.

UNASSIGNED: Extreme risk protection orders (ERPOs)-also known as red flag, risk warrant, and gun violence restraining orders-authorize law enforcement, family members, and sometimes others to petition a court to remove firearms from and prevent the acquisition of new firearms by a person judged to pose an immediate danger to themselves or others. Previous estimates suggest that 1 suicide is prevented for every 10 ERPOs issued, a number needed to treat that depends critically on the counterfactual estimate of the proportion of suicidal acts by ERPO respondents that would have involved firearms in the absence of ERPOs.
UNASSIGNED: To empirically inform updated estimates of the number of ERPOs needed to prevent 1 suicide.
UNASSIGNED: This cohort study used data from California for method-specific suicides by handgun ownership (October 18, 2004, to December 31, 2015). Handgun-owning suicide decedents in California were identified using individual-level registry data about lawful handgun ownership linked to cause-specific mortality for a cohort of more than 25 million adults. The study also used data from Connecticut for method-specific suicides among ERPO respondents who died by suicide, extracted from published data (October 1999 to June 2013). Data analysis was performed in December 2023.
UNASSIGNED: Handgun ownership.
UNASSIGNED: The primary outcomes were the number and distribution of suicidal acts by handgun owners in California, estimated using method-specific suicide mortality data and published case fatality ratios, and the counterfactual number and distribution of suicidal acts and deaths among ERPO respondents in Connecticut had no ERPOs been issued.
UNASSIGNED: A total of 1216 handgun owners (mean [SD] age, 50 [18] years; 1019 male [83.8%]) died by suicide during the study period. Among male handgun owners in California, 28% of suicidal acts involved firearms, 54% involved drug poisoning, 9% involved cutting or piercing, 3% involved hanging or suffocation, 2% involved poisoning with solids and/or liquids, and the remaining 4% involved other methods. Assuming this distribution approximates the counterfactual distribution among ERPO respondents in Connecticut in the absence of ERPOs, 1 suicide death was prevented for every 22 ERPOs issued.
UNASSIGNED: The estimates produced by this cohort study of California handgun owners suggest that ERPOs can play an important role in averting deaths among high-risk individuals.

Gun violence, often characterized as a singular issue, is not one cohesive problem. Instead, it takes many forms resulting from the complex interplay of multiple factors. Outcomes of gun violence also vary significantly. They may be (a) physically non-injurious (a gun is brandished), (b) injurious but non-lethal, or (c) lethal. To understand and address gun violence effectively, it is essential to consider various risk factors for both non-lethal and lethal gun violence victimization, using a comprehensive, comparative framework. We present a novel comparative framework for better understanding gun violence, and for developing policy responses to this violence. We disaggregate gun violence into its various forms and propose a conceptualization of risk factors in discrete categories, each with important implications for policy intervention. While we emphasize the value of this framework for understanding and combatting interpersonal gun violence in America, the research and policy approaches discussed here should be equally applicable to other international contexts with gun violence as a serious public health issue as well.
