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: Most U.S. K-12 schools have adopted safety tactics and policies like arming teachers and installing metal detectors, to address intentional school gun violence. However, there is minimal research on their effectiveness. Furthermore, sociodemographic factors may influence their implementation. Controlled studies are necessary to investigate their impact on gun violence and related disciplinary outcomes.
OBJECTIVE: The paper outlines the protocol for a case-control study examining gun violence prevention policies in U.S. K-12 schools. The study aims to investigate if there is an association between the total number and type of specific safety tactics and policies and the occurrence of intentional shootings in K-12 public schools, student disciplinary outcomes, and if urbanicity, economic, and racial factors modify these associations.
METHODS: We will create a nationally representative dataset for this study and ascertain a full census of case schools (schools that experienced intentional gunfire on the campus during school hours since 2015) through national school shooting databases. Matched control schools will be randomly selected from U.S. Department of Education\'s national database of all public schools. We will analyze 27 school safety strategies organized into seven key exposure groupings.
RESULTS: Supported by the National Institutes for Child Health and Development (R01HD108027-01) and having received Institutional Review Board approval, our study is currently in the data collection phase. Our analytical plan will determine the association between the number and type of school safety tactics and policies with the occurrence of intentional shootings and suspensions and expulsions in a national sample of approximately 650 K-12 public schools. Additional analyses will investigate the effect modification of specific covariates.
CONCLUSIONS: As the first national, controlled study, its results will provide novel and needed data on the effectiveness of school safety tactics and policies in preventing intentional shootings at K-12 public schools.

We aimed to explore perspectives of teenagers on their exposure to gun violence (GV), their knowledge and attitudes towards firearm injury prevention (FIP) efforts, and how to counsel them about FIP. Teens from two single-sex Bronx Catholic high schools participated in videoconferencing focus groups. Participants completed an online survey collecting demographic information and Likert-scale scoring of attitudes towards GV. Quantitative data was analyzed with descriptive statistics. Focus group discussions were recorded and transcribed. Using Dedoose, two investigators independently coded data and achieved consensus using content analysis. Six focus groups (3 from each school, n = 28 participants) were held from October-November 2020. A total of 27 participants completed the survey. Eighty-one percent of respondents agreed \"Doctors should talk to teens about gun safety.\" During focus groups, participants reported personal, community, and entertainment media exposure to GV. GV elicited many emotions, including fear and frustration. Teens identified factors contributing to GV that should be addressed, including poverty, racism, and mental illness. Most had not received prior FIP education and desired more information from trusted adults. They preferred discussions over written materials and information given over time. Teens were open to doctors counseling on FIP during healthcare visits and suggested including screening questions on surveys, conversations during healthcare maintenance visits, and classroom talks by physicians. Bronx teens are exposed to and distressed by community GV. They desired more FIP education, including physician counseling during healthcare visits. Next steps are to create and test FIP guidance for adolescents.

Guns and gun violence have become a widely discussed and hotly debated concern across the United States. With gun violence on the rise and mass shootings provoking powerful emotional outrage, the question often rests with what can or should be done to rectify these societal issues. This paper examines the attitudes of guns expressed through two qualitative interviews of gun owners in the United States. The paper observes many of the same outrage amongst these gun owners of Americans with seemingly little to show in the way of public policy progress for protecting citizens. Still, differences persist in what should be or can be done. The paper recommends more expansive study on this critical group of citizens involved in future United States gun safety and policy debate.

BACKGROUND: The aim of the study was to have youth participate in the design and implementation of a research project set within a child rights framework to better understand high schoolers\' perceptions of safety in their school and community.
RESULTS: Between June 2020 and March 2021, a team of East Harlem, New York high school students, participated as co-researchers to modify the United Nations Children\'s Fund Child Friendly Cities Initiative Survey to suit their needs. Due to the COVID-19 pandemic, the final survey was conducted through an online remote classes system during advisory school classes, accompanied by brief focused group discussions. The novel process of conducting an interactive qualitative and quantitative virtual survey during a pandemic via youth participatory action research is outlined in this paper.
CONCLUSIONS: Our results demonstrate that youth participatory action research can be utilized as part of a child rights framework approach to assess the views of youth regarding community safety and violence prevention.

BACKGROUND: Survivors of gun violence have significant sequelae including reinjury with a firearm and mental health disorders that often go undiagnosed and untreated. The Screening and Tool for Awareness and Relief of Trauma (START) is a targeted behavioral mental health intervention developed for patients who come from communities of color with sustained and persistent trauma.
METHODS: In this pilot study, we evaluate the feasibility of completing a randomized controlled trial to test the START intervention. Using a mixed methods study design, we used both quantitative and qualitative data collection to assess the START intervention and the feasibility of completing a randomized controlled trial. The purpose of this study was to estimate important study parameters that would enable a future randomized controlled trial.
RESULTS: We were able to make conclusions about several crucial domains of a behavioral intervention trial: (1) recruitment and retention-we had a high follow-up rate, but our recruitment was low (34% of eligible participants); (2) acceptability of the intervention-the addition of audiovisual resources would make the tools more accessible; (3) feasibility of the control-more appropriate for a stepped wedge cluster randomized controlled trial design; (4) intervention fidelity-there was an 81% concordance rate between the fidelity survey results and the audio recordings; (5) approximate effect size-there was a 0.4-point decrease in the PTSD Checklist-Civilian Version in the control compared with a 10.7-point decrease in the treatment group for the first month.
CONCLUSIONS: While it was feasible to conduct a randomized controlled trial, our findings suggest that a stepped wedge cluster randomized controlled trial design may be the most successful trial design for the START intervention. In addition, the inclusion of a \"credible messenger\" to recruit participants into the study and the development of audiovisual resources for START would improve recruitment and effectiveness.

BACKGROUND: The USA has failed to codify the protection of children from gun violence (GV) as a human right. This study employs a youth participatory action research methodology, within the framework of the United Nations Convention on the Rights of the Child (UNCRC), to investigate the relationships between GV exposure, self-identified gender and perceptions of children\'s rights and safety.
METHODS: An anonymous survey based on UNICEF USA\'s Child Friendly Cities Initiative interactive survey tool targeting adolescents was modified by East Harlem, New York high school student co-researchers in collaboration with near-peer graduate students. The 61-question survey was administered at an East Harlem high school. Analysis consisted of univariate, bivariate and logistic regression using SPSS®.
RESULTS: A total of 153 students completed the survey: 48.4% self-identified as male and 45.8% as female. Thirty-five percent reported witnessing GV. Most (79.1%) were aware of child rights regardless of gender or GV exposure but there were differences in perceptions of safety. Fifteen percent of females reported never feeling safe at school compared to 3% of males (p = 0.01). Females were 2.2 times as likely as males to report transportation waiting areas as never safe (p = 0.008). Almost a third of females reported never feeling safe from sexual harassment in public, compared to 10% of males (p = 0.004). In multivariable logistic regression adjusted for gender, race/ethnicity and grade level, students who witnessed GV were 4.6 times more likely to report never feeling safe from violence (95% CI 1.7-12.4). Thirty percent of students who witnessed GV reported not attending school because of safety concerns. Students who witnessed GV had 2.2 times the odds of carrying a weapon to school (95% CI 1.1-4.5). These patterns continued for other perceptions of safety.
CONCLUSIONS: The students in this study affirmed their rights to participate and express their views on matters that may affect them, as articulated in the UNCRC. The study revealed differences in perceptions of safety by self-identified gender and identified gun violence as a major contributor of youth\'s perception of lack of safety. The study evinces the efficacy of employing YPAR methodology to identify and answer youth concerns of community safety and prioritize honoring child rights.

Firearm violence is a major public health problem in the United States, yet most states lack a mechanism to temporarily remove firearms from individuals who are at high and imminent risk of harming themselves or others and are not otherwise prohibited. Extreme risk protection order (ERPO) laws are intended to close this gap. The current study examines the passage of California\'s gun violence restraining order (GVRO) bill using Kingdon\'s multiple streams framework.
This study was based on an analysis of interview data from six key informants involved in the passage of the GVRO legislation.
Findings indicate policy entrepreneurs framed the problem and designed the policy to target individuals at behavioral risk of imminent firearm violence. Policy entrepreneurs comprised an integrated policy network that engaged in a lengthy period of collaboration and bargained with interest groups to yield a bill that satisfied diverse concerns.
This case study may inform efforts in other states to pass ERPO policies and other firearm safety laws.

Gun violence disproportionately affects young Black men, but the impact extends to families and communities. Those at highest risk are teens delinquent of gun crimes. While there is no nationally accepted juvenile rate of recidivism, previous literature reveals rearrest rates from 50% to 80% in high-risk youth, and some reports show that up to 40% of delinquent juveniles are incarcerated in adult prisons before the age of 25 years. We hypothesize that Project Inspire, a hospital-led comprehensive intervention, reduces recidivism among high-risk teens.
Led by a level 1 trauma center, key community stakeholders including the juvenile court, city, and city police department joined forces to create a community-wide program aimed at curbing gun violence in high-risk individuals. Participants, aged 13 to 18 years, are selected by the juvenile gun court. They underwent a rigorous 3-week program with a curriculum incorporating the following: trauma-informed training and confidence building, educational/professional development, financial literacy, entrepreneurship, and career-specific job shadowing and mentorship. Rates of recidivism were measured annually.
Project Inspire has hosted two classes in 2018 and 2019, graduating nine participants aged 14 to 17 years. Sixty-seven percent were Black. All were males. At 1 year, none of the graduates reoffended. At 2 years, one participant reoffended. At 3 years, no additional participants reoffended. No graduate reoffended as a juvenile. Thus, the overall rate of recidivism for Project Inspire is 11% to date. Eighty-nine percent of graduates received a diploma, general educational development, or obtained employment.
Project Inspire is a hospital-led initiative that effectively reduces recidivism among juveniles delinquent of gun crimes. This sets the framework for trauma centers nationwide to lead in establishing impactful, comprehensive, gun-violence intervention strategies.
