This Viewpoint summarizes current data on firearm injuries in the US, discusses the limitations of available data sources, and proposes measures for a comprehensive system to track firearm injury and ...death
The violent death of any child is an individual tragedy whose effects ripple through families, peers, and communities. Although these losses and their consequences are fundamentally preventable, they ...are becoming more common, not less, despite numerous advances in other aspects of child safety. Indeed, firearm injury has surpassed motor vehicle crash to become the leading cause of death among children. Here, Wilson et al analyze longitudinal national data to provide compelling insights into the characteristics and circumstances of homicides of children that emphasize important avenues for prevention.
IMPORTANCE: Firearm injury research in the US has focused on fatal injuries. The incidence and epidemiologic factors associated with nonfatal firearm injuries are less understood. OBJECTIVE: To ...evaluate estimates of incidence and trends over time of fatal and nonfatal firearm injuries. DESIGN, SETTING, AND PARTICIPANTS: A cross-sectional, ecologic study was conducted using data throughout the US from 2009 to 2017. Data on fatal injuries from the Centers for Disease Control and Prevention were combined with national data on emergency department visits for nonfatal firearm injury from the Nationwide Emergency Department (ED) sample. Data analysis was conducted from August 2019 to September 2020. EXPOSURES: Firearm injuries identified with International Classification of Diseases external cause of injury codes and categorized by intent of injury, age group, and urban-rural location. MAIN OUTCOMES AND MEASURES: Incidence, case fatality rate, and trends over time of firearm injury according to intent, age group, and urban-rural location. RESULTS: From 2009 to 2017, there was a mean of 85 694 ED visits for nonfatal firearm injury and 34 538 deaths each year. An annual mean of 26 445 deaths (76.6%) occurred outside of the hospital. Assault was the most common overall mechanism (38.9%), followed by unintentional injuries (36.9%) and intentional self-harm (19.6%). Self-harm, which accounted for 21 128 deaths (61.2%), had the highest case fatality rate (89.4%; 95% CI, 88.5%-90.4%), followed by assault (25.9%; 95% CI, 23.7%-28.6%) and legal intervention (23.4%; 95% CI, 21.6%-25.5%). Unintentional injuries were the most common nonfatal injuries (43 729 51.0%) and had the lowest case fatality rate (1.2%; 95% CI, 1.1%-1.3%). Self-harm deaths, 87.8% of which occurred outside the hospital, increased in all age groups in both rural and urban areas during the study period and were most common among people aged 55 years and older. The rate of fatal assault injuries was higher in urban than in rural areas (16.6 vs 9.0 per 100 000 per year) and highest among people aged 15 to 34 years (38.6 per 100 000 per year). Rates of unintentional injury were higher in rural than in urban areas (18.5 per 100 000 vs 12.4 per 100 000). CONCLUSIONS AND RELEVANCE: In this cross-sectional study, suicide appears to be the most common cause of firearm injury death in the US, and most people who die from suicide never reach the hospital. These findings suggest that assaults and unintentional injuries account for most nonfatal and overall firearm injuries and for most of the injuries that are treated in hospitals.
IMPORTANCE: Firearm laws in one state may be associated with increased firearm death rates from homicide and suicide in neighboring states. OBJECTIVE: To determine whether counties located closer to ...states with lenient firearm policies have higher firearm death rates. DESIGN, SETTING, AND PARTICIPANTS: This cross-sectional study of firearm death rates by county for January 2010 to December 2014 examined data from the US Centers for Disease Control and Prevention for firearm suicide and homicide decedents for 3108 counties in the 48 contiguous states of the United States. EXPOSURES: Each county was assigned 2 scores, a state policy score (range, 0-12) based on the strength of its state firearm laws, and an interstate policy score (range, −1.33 to 8.31) based on the sum of population-weighted and distance-decayed policy scores for all other states. Counties were divided into those with low, medium, and high home state and interstate policy scores. MAIN OUTCOMES AND MEASURES: County-level rates of firearm, nonfirearm, and total homicide and suicide. With multilevel Bayesian spatial Poisson models, we generated incidence rate ratios (IRR) comparing incidence rates between each group of counties and the reference group, counties with high home state and high interstate policy scores. RESULTS: Stronger firearm laws in a state were associated with lower firearm suicide rates and lower overall suicide rates regardless of the strength of the other states’ laws. Counties with low state scores had the highest rates of firearm suicide. Rates were similar across levels of interstate policy score (low: IRR, 1.34; 95% credible interval CI, 1.11-1.65; medium: IRR, 1.36, (95% CI, 1.15-1.65; and high: IRR, 1.43; 95% CI, 1.20-1.73). Counties with low state and low or medium interstate policy scores had the highest rates of firearm homicide. Counties with low home state and interstate scores had higher firearm homicide rates (IRR, 1.38; 95% CI, 1.02-1.88) and overall homicide rates (IRR, 1.32; 95% CI, 1.03-1.67). Counties in states with low firearm policy scores had lower rates of firearm homicide only if the interstate firearm policy score was high. CONCLUSIONS AND RELEVANCE: Strong state firearm policies were associated with lower suicide rates regardless of other states’ laws. Strong policies were associated with lower homicide rates, and strong interstate policies were also associated with lower homicide rates, where home state policies were permissive. Strengthening state firearm policies may prevent firearm suicide and homicide, with benefits that may extend beyond state lines.
OBJECTIVES:To review the public health approach to preventing and treating firearm violence.
DATA SOURCES:Peer-reviewed, published scholarship and federal data systems.
STUDY ...SELECTION:English-language, indexed research articles on the epidemiology, risk, prevention, and consequences of firearm violence.
DATA EXTRACTION:This narrative review includes findings related to the epidemiology and impact of firearm violence, focusing on short- and long-term outcomes. Evidence supporting interventions at the individual, agent, and environmental level to reduce firearm-related harm was examined.
DATA SYNTHESIS:Firearm violence is a major public health challenge in the Unites States. The consequences of firearm violence reach beyond the nearly 40,000 firearm-related deaths and 90,000 firearm-related injuries each year. Firearm violence, including self-harm, assault, and unintentional injury, affects the health of individuals, families, communities, and health systems. Data sources remain inadequate, however, to fully capture these impacts. Treating firearm violence as a disease and taking a public health approach to prevention and treatment is key to reducing the harms of firearm violence. Using a public health framework not only recognizes the physical and mental consequences of firearm violence but also focuses our attention on underlying causes and on innovative, multi-level interventions to reduce the harms of firearm violence.
CONCLUSIONS:The public health approach positions clinicians to change the conversation from political diatribe of pro-gun and anti-gun to systematically reducing injury and death. To achieve comparable success, we must design, test, and implement effective interventions at the environmental, policy, technological, and individual levels to prevent firearm violence. We must collect robust data on firearm violence and its consequences. And we must reckon with the conditions of inequality and disadvantage that feed violence through all means.
This study uses police department registry data to describe trends in incidence of firearm shootings and deaths in January-November 2020, before and after the closure of nonessential businesses in ...March, the killing of George Floyd in May, and the partial lifting of containment policies in June.
