Nonfatal Firearm Violence Trends on the Westside of Chicago Between 2005 and 2016

Youth Exposure to Gun, Knife, and Physical Assaults: Assessing PTSD Symptoms Across Types of Assaults, Race, Ethnicity, Sex, and Context

This study examined posttraumatic stress disorder (PTSD) symptoms in relation to physical assaults and weapons-related victimization, as well as the moderating roles of demographic characteristics and the context of victimization. The sample consisted of 910 racially and ethnically diverse adolescents and young adults from an urban commuter college in the Northeast U.S. Findings include significant sex differences and racial differences in reported victimization and symptoms. Men reported significantly more physical assaults, gun victimizations, and knife victimizations than women. Black participants reported significantly more gun victimization than all other groups, and Black, White, and Asian participants reported significantly more physical assault experiences than Latinx participants. Individuals victimized by physical assault or by gun victimization were more than twice as likely to report clinically significant PTSD symptoms than individuals without such experiences, even after adjusting for demographic differences. In addition, for gun victimization in the community, a two-way interaction (gun victimization by race) and a three-way interaction (gun victimization by race by sex) were significantly associated with clinically significant PTSD symptoms. Gun victimization in the community, which disproportionately impacts Black men, was the only context in which PTSD symptoms were highest for men compared to women. The overall finding of lower PTSD symptoms among men suggests that clinical practice must include an intentional focus on violence victimization, including the use of weapons, as well as the various ways that distress might manifest among men. In addition to symptoms of PTSD, other symptoms of distress, including substance use, anger, and retaliatory aggression, should be considered. Public policy and public health must also direct attention to the use of weapons in violence victimization and the proliferation of weapons violence.

Changes in Health Care Spending, Use, and Clinical Outcomes After Nonfatal Firearm Injuries Among Survivors and Family Members : A Cohort Study

BACKGROUND

Despite increasing awareness of firearm-related deaths, evidence on the clinical and economic implications of nonfatal firearm injuries is limited.

OBJECTIVE

To measure changes in clinical and economic outcomes after nonfatal firearm injuries among survivors and their family members.

DESIGN

Cohort study.

SETTING

MarketScan Medicare and commercial claims data, 2008 to 2018.

PARTICIPANTS

6498 survivors of firearm injuries matched to 32 490 control participants and 12 489 family members of survivors matched to 62 445 control participants.

INTERVENTION

Exposure to nonfatal firearm injury as a survivor or family member of a survivor.

MEASUREMENTS

Changes in health care spending, use, and morbidity from preinjury through 1 year postinjury relative to control participants, on average and by type and severity of firearm injury.

RESULTS

After nonfatal firearm injury, medical spending increased $2495 per person per month (402%) and cost sharing increased $102 per person per month (176%) among survivors relative to control participants (P < 0.001) in the first year after injury, driven by an increase in the first month of $25 554 (4122%) in spending and $1112 (1917%) in cost sharing per survivor (P < 0.001). All categories of health care use increased relative to the control group. Survivors had a 40% increase in pain diagnoses, a 51% increase in psychiatric disorders, and an 85% increase in substance use disorders after firearm injury relative to control participants (P < 0.001), accompanied by increased pain and psychiatric medications. Family members had a 12% increase in psychiatric disorders relative to their control participants (P = 0.003). These overall clinical and economic changes were driven by intentional firearm injuries and more severe firearm injuries.

LIMITATION

Precision of diagnostic codes and generalizability to other patient populations, including Medicaid and uninsured patients.

CONCLUSION

In survivors, nonfatal firearm injuries led to increases in psychiatric disorders, substance use disorders, and pain diagnoses, alongside substantial increases in health care spending and use. In addition, mental health worsened among family members.

Declining health risk exposure among Chicago public high school students: Trends from the Youth Risk Behavior Survey 1997-2017

There have been improvements nationally in teenagers' self-reported health risk since the 1990s. This study provides an overview of trends in substance use, sexual health, violence and victimization, and suicide risk among Chicago Public High School (CPS) students over a 20-year period. We compared responses to 29 identically worded items from the 1997, 2007, and 2017 Chicago Youth Risk Behavior Survey (YRBS) in the four domains. We show changes in responses across individual items, mean changes across the four domains, and change in the proportion of students with highest risk exposure (≥10 affirmative responses). Analyses control for CPS students' grade, sex, and race/ethnicity. Reductions in substance use, sexual health risk, and violence and victimization (30, 40% and 40% in the mean number of affirmative responses, respectively) were observed. Suicide risk showed an initial improvement from 1997 to 2007, only to worsen by 2017 and show little difference from 1997. There was an approximate 70% decrease in the likelihood of being in the high multiple risk category (≥10 affirmative responses) in 2017 compared to 1997 (OR 0.33; CI 0.22-0.49). In alignment with national trends, our study documents significant improvement in Chicago public high school students' long-term health risk exposure over the 20-year study period, with the notable exception of suicide risk. This study emphasizes the need to invest in strategies both inside and outside of the classroom to mitigate the effect of adversity and promote protective factors, which are at the root of academic success and overall wellbeing.
