Nonfatal Emergency Department Visits Associated with Fall-Related Fractured Skulls of Infants Aged 0-4 Months.

BACKGROUND: Children aged 0-4 years have the highest rate of emergency department (ED) visits for traumatic brain injury (TBI); falls are the leading cause. Infants younger than 2 years are more likely to sustain a fractured skull after a fall. OBJECTIVE: This study examined caregiver actions and products associated with ED visits for fall-related fractured skulls in infants aged 0-4 months. METHODS: Data were analyzed from the 2001-2017 National Electronic Injury Surveillance System-All Injury Program. Case narratives of infants aged 0-4 months who visited an ED for a fall-related skull fracture were examined to code caregiver actions preceding the fall. Product codes determined fall location and product type involved (e.g., flooring, bed, or stairs). All national estimates were weighted. RESULTS: There were more than 27,000 ED visits (weighted estimate) of infants aged 0-4 months for a nonfatal fall-related fractured skull between 2001 and 2017. Most were younger than 2 months (46.7%) and male (54.4%). Falls occurred primarily in the home (69.9%) and required hospitalization (76.4%). Primary caregiver actions coded involved placing (58.6%), dropping (22.7%), and carrying an infant (16.6%). Floor surfaces were the most common product (mentioned in 24.0% of the cases). CONCLUSIONS: Fall-related fractured skulls are a health and developmental concern for infants, highlighting the importance of a comprehensive assessment at the time of the injury to better understand adult actions. Findings indicated the need to develop prevention messages that include safe carrying and placement of infants.

Economic Cost of U.S. Suicide and Nonfatal Self-harm.

INTRODUCTION: The U.S. age-adjusted suicide rate is 35% higher than two decades ago and the COVID-19 pandemic era highlighted the urgent need to address nonfatal self-harm, particularly among youth. This study aimed to report the estimated annual economic cost of U.S. suicide and nonfatal self-harm. METHODS: In 2023 CDC's WISQARS Cost of Injury provided the retrospective number of suicides and nonfatal self-harm injury emergency department (ED) visits from national surveillance sources by sex and age group, as well as the estimated annual economic cost of associated medical spending, lost work productivity, reduced quality of life from injury morbidity, and avoidable mortality based on the value of statistical life during 2015-2020. RESULTS: The economic cost of suicide and nonfatal self-harm averaged $510 billion (2020 USD) annually, the majority from life years lost to suicide. Working-aged adults (aged 25-64 years) comprised nearly 75% of the average annual economic cost of suicide ($356B of $484B) and children and younger adults (aged 10-44 years) comprised nearly 75% of the average annual economic cost of nonfatal self-harm injuries ($19B of $26B). CONCLUSIONS: Suicide and self-harm have substantial societal costs. Measuring the consequences in terms of comprehensive economic cost can inform investments in suicide prevention strategies.

The Health and Economic Impact of Youth Violence by Injury Mechanism.

INTRODUCTION: Violence is a leading cause of morbidity and mortality among U.S. youth. More information on the health and economic burden of the most frequent assault mechanisms-or, causes (e.g., firearms, cut/pierce)-can support the development and implementation of effective public health strategies. Using nationally representative data sources, this study estimated the annual health and economic burden of U.S. youth violence by injury mechanism. METHODS: In 2023, CDC's WISQARS provided the number of homicides and nonfatal assault ED visits by injury mechanism among U.S. youth aged 10-24 years in 2020, as well as the associated average economic costs of medical care, lost work, morbidity-related reduced quality of life, and value of statistical life. The Healthcare Cost and Utilization Project Nationwide Emergency Department Sample provided supplemental nonfatal assault incidence data for comprehensive reporting by injury mechanism. RESULTS: Of the $86B estimated annual economic burden of youth homicide, $78B was caused by firearms, $4B by cut/pierce injuries, and $1B by unspecified causes. Of the $36B billion estimated economic burden of nonfatal youth violence injuries, $19B was caused by struck by/against injuries, $3B by firearm injuries, and $365M by cut/pierce injuries. CONCLUSIONS: The lethality of assault injuries affecting youth when a weapon is explicitly or likely involved is high-firearms and cut/pierce injuries combined account for nearly all youth homicides compared to one-tenth of nonfatal assault injury ED visits. There are numerous evidence-based policies, programs, and practices to reduce the number of lives lost or negatively impacted by youth violence.

Emergency Department Visits for Alcohol-Associated Falls Among Older Adults in the United States, 2011 to 2020.

STUDY OBJECTIVE: The aim of this study was to examine the epidemiology of alcohol-associated fall injuries among older adults aged ≥65 years in the United States. METHODS: We included emergency department (ED) visits for unintentional fall injuries by adults from the National Electronic Injury Surveillance System-All Injury Program during 2011 to 2020. We estimated the annual national rate of ED visits for alcohol-associated falls and the proportion of these falls among older adults' fall-related ED visits using demographic and clinical characteristics. Joinpoint regression was performed to examine trends in alcohol-associated ED fall visits between 2011 and 2019 among older adult age subgroups and to compare these trends with those of younger adults. RESULTS: There were 9,657 (weighted national estimate: 618,099) ED visits for alcohol-associated falls, representing 2.2% of ED fall visits during 2011 to 2020 among older adults. The proportion of fall-related ED visits that were alcohol-associated was higher among men than among women (adjusted prevalence ratio [aPR]=3.6, 95% confidence interval [CI] 2.9 to 4.5). The head and face were the most commonly injured body parts, and internal injury was the most common diagnosis for alcohol-associated falls. From 2011 to 2019, the annual rate of ED visits for alcohol-associated falls increased (annual percent change 7.5, 95% CI 6.1 to 8.9) among older adults. Adults aged 55 to 64 years had a similar increase; a sustained increase was not detected in younger age groups. CONCLUSION: Our findings highlight the rising rates of ED visits for alcohol-associated falls among older adults during the study period. Health care providers in the ED can screen older adults for fall risk and assess for modifiable risk factors such as alcohol use to help identify those who could benefit from interventions to reduce their risk.

Injury-Related Emergency Department Visits During the COVID-19 Pandemic.

INTRODUCTION: On March 13, 2020, the U.S. declared COVID-19 to be a national emergency. As communities adopted mitigation strategies, there were potential changes in the trends of injuries treated in emergency department. This study provides national estimates of injury-related emergency department visits in the U.S. before and during the pandemic. METHODS: A secondary retrospective cohort study was conducted using trained, on-site hospital coders collecting data for injury-related emergency department cases from medical records from a nationally representative sample of 66 U.S. hospital emergency departments. Injury emergency department visit estimates in the year before the pandemic (January 1, 2019-December 31, 2019) were compared with estimates of the year of pandemic declaration (January 1, 2020-December 31, 2020) for overall nonfatal injury-related emergency department visits, motor vehicle, falls-related, self-harm-, assault-related, and poisoning-related emergency department visits. RESULTS: There was an estimated 1.7 million (25%) decrease in nonfatal injury-related emergency department visits during April through June 2020 compared with those of the same timeframe in 2019. Similar decreases were observed for emergency department visits because of motor vehicle‒related injuries (199,329; 23.3%) and falls-related injuries (497,971; 25.1%). Monthly 2020 estimates remained relatively in line with 2019 estimates for self-harm‒, assault-, and poisoning-related emergency department visits. CONCLUSIONS: These findings provide updates for clinical and public health practitioners on the changing profile of injury-related emergency department visits during the COVID-19 pandemic. Understanding the short- and long-term impacts of the pandemic is important to preventing future injuries.

Emergency Department Visits for Bicycle-Related Traumatic Brain Injuries Among Children and Adults - United States, 2009-2018.

Bicycling leads to the highest number of sport and recreation-related emergency department (ED) visits for traumatic brain injuries (TBIs) in the United States (1). Because bicycling continues to grow in popularity,* primarily among U.S. adults, examining the strategies that mitigate the risk for TBI is important. CDC analyzed data from the National Electronic Injury Sursveillance System-All Injury Program (NEISS-AIP) to determine the incidence of EDs for bicycle-related TBIs during 2009-2018. An estimated 596,972 ED visits for bicycle-related TBIs occurred in the United States during the study period. Rates of ED visits were highest among adult males (aged ≥18 years) and among children and adolescents aged 10-14 years during 2009-2018. Overall, the rate of ED visits for bicycle-related TBIs decreased by approximately one half (48.7%) among children and by 5.5% among adults. As the number of persons riding bicycles increases, expansion of comprehensive bicycling safety interventions for bicyclists and drivers by states and local communities, such as interventions to increase driver compliance with traffic laws and helmet use among riders, improvements in bicycling infrastructure, and customized interventions for males and other groups at high risk might help reduce bicycle-related injuries.

Evaluation of the National Electronic Injury Surveillance System - All injury program's self-directed violence data, United States, 2018.

INTRODUCTION: National estimates for nonfatal self-directed violence (SDV) presenting at EDs are calculated from the National Electronic Injury Surveillance System - All Injury Program (NEISS-AIP). In 2005, the Centers for Disease Control and Prevention and Consumer Product Safety Commission added several questions on patient characteristics and event circumstances for all intentional, nonfatal SDV captured in NEISS-AIP. In this study, we evaluated these additional questions along with the parent NEISS-AIP, which together is referred to as NEISS-AIP SDV for study purposes. METHODS: We used a mixed methods design to evaluate the NEISS-AIP SDV as a surveillance system through an assessment of key system attributes. We reviewed data entry forms, the coding manual, and training materials to understand how the system functions. To identify strengths and weaknesses, we interviewed multiple key informants. Finally, we analyzed the NEISS-AIP SDV data from 2018-the most recent data year available-to assess data quality by examining the completeness of variables. RESULTS: National estimates of SDV are calculated from NEISS-AIP SDV. Quality control activities suggest more than 99% of the cause and intent variables were coded consistently with the open text field that captures the medical chart narrative. Many SDV variables have open-ended response options, making them difficult to efficiently analyze. CONCLUSIONS: NEISS-AIP SDV provides the opportunity to describe systematically collected risk factors and characteristics associated with nonfatal SDV that are not regularly available through other data sources. With some modifications to data fields and yearly analysis of the additional SDV questions, NEISS-AIP SDV can be a valuable tool for informing suicide prevention. Practical Applications: NEISS-AIP may consider updating the SDV questions and responses and analyzing SDV data on a regular basis. Findings from analyses of the SDV data may lead to improvements in ED care.

Fall-related traumatic brain injury in children ages 0-4 years.

INTRODUCTION: Falls are the leading cause of traumatic brain injury (TBI) for children in the 0-4 year age group. There is limited literature pertaining to fall-related TBIs in children age 4 and under and the circumstances surrounding these TBIs. This study provides a national estimate and describes actions and products associated with fall-related TBI in this age group. METHOD: Data analyzed were from the 2001-2013 National Electronic Injury Surveillance System-All Injury Program (NEISS-AIP), a nationally representative sample of emergency departments (ED). Case narratives were coded for actions associated with the fall, and product codes were abstracted to determine fall location and product type. All estimates were weighted. RESULTS: An estimated 139,001 children younger than 5 years were treated annually in EDs for nonfatal, unintentional fall-related TBI injuries (total = 1,807,019 during 2001-2013). Overall, child actions (e.g., running) accounted for the greatest proportion of injuries and actions by others (e.g., carrying) was highest for children younger than 1 year. The majority of falls occurred in the home, and involved surfaces, fixtures, furniture, and baby products. CONCLUSIONS: Fall-related TBI in young children represents a significant public health burden. The majority of children seen for TBI assessment in EDs were released to home. Prevention efforts that target parent supervision practices and the home environment are indicated. Practical applications: Professionals in contact with parents of young children can remind them to establish a safe home and be attentive to the environment when carrying young children to prevent falls.

Traumatic brain injury-related hospitalizations and deaths among American Indians and Alaska natives - United States, 2008-2014.

INTRODUCTION: Despite progress, injury remains the leading cause of preventable death for American Indian and Alaska Natives (AI/AN), aged 1 to 44. There are few publications on injuries among the AI/AN population, especially those on traumatic brain injury (TBI). A TBI can cause short- or long-term changes in cognition, communication, and/or emotion. METHODS: To describe changes over time in TBI incidence by mechanism of injury, injury intent, and age group among AI/ANs, the CDC analyzed hospitalization and death data from the 2008-2014 Healthcare Cost and Utilization Project (HCUP) National Inpatient Sample (NIS) and the National Vital Statistics System (NVSS), respectively. RESULTS: From 2008-2014, the incidence of TBI-related hospitalizations increased by 32% (1,477 in 2008 to 1,945 in 2014) and resulted in a 21% increase in age-adjusted rates of people hospitalized with TBI. TBI-related deaths increased in number (569 in 2008 to 644 in 2014) and age-adjusted rate (22.7 in 2008 to 25.4 in 2014) by approximately 13% and 12%, respectively. Motor-vehicle crashes were the leading cause of TBI-related deaths among AI/ANs aged 0-54 years. Practical application: Prevention efforts should focus on increasing motor-vehicle safety and advancing prevention strategies for other leading causes of TBI, including: falls, intentional self-harm, and assaults.

Pool Chemical Injuries in Public and Residential Settings - United States, 2008-2017, and New York, 2018.

Pool chemicals are added to water in treated recreational water venues (e.g., pools, hot tubs/spas, and water playgrounds) primarily to protect public health. Pool chemicals inactivate pathogens (e.g., chlorine or bromine), optimize pH (e.g., muriatic acid), and increase water clarity, which helps prevent drowning by enabling detection of distressed swimmers underwater. However, pool chemicals can cause injuries if mishandled. To estimate the annual number of U.S. emergency department (ED) visits for pool chemical injuries, CDC analyzed 2008-2017 data from the National Electronic Injury Surveillance System (NEISS), operated by the U.S. Consumer Product Safety Commission (CPSC). During 2015-2017, pool chemical injuries led to an estimated 13,508 (95% confidence interval [CI] = 9,087-17,929) U.S. ED visits; 36.4% (estimated 4,917 [95% CI = 3,022-6,811]) of patients were aged <18 years. At least 56.3% (estimated 7,601 [95% CI = 4,587-10,615]) of injuries occurred at a residence. Two thirds of the injuries occurred during the period from Memorial Day weekend through Labor Day. This report also describes a toxic chlorine gas incident that occurred at a public pool in New York in 2018. Pool chemical injuries are preventable. CDC's Model Aquatic Health Code (MAHC) is an important resource that operators of public treated recreational water venues (e.g., at hotels, apartment complexes, and waterparks) can use to prevent pool chemical injuries.

Nonfatal Assaults and Homicides Among Adults Aged ≥60 Years - United States, 2002-2016.

Since interpersonal violence was recognized as a public health problem in the 1970s, much attention has focused on preventing violence among young persons and intimate partners (1). Violence directed against older adults (≥60 years) has received less attention, despite the faster growth of this population than that of younger groups (2). Using data from the National Electronic Injury Surveillance System-All Injury Program (NEISS-AIP) and the National Vital Statistics System (NVSS), CDC analyzed rates of nonfatal assaults and homicides against older adults during 2002-2016. Across the 15-year period, the nonfatal assault rate increased 75.4% (from 77.7 to 136.3 per 100,000) among men, and from 2007 to 2016, increased 35.4% (from 43.8 to 59.3) among women. From 2010 to 2016, the homicide rate increased among men by 7.1%, and a 19.3% increase was observed from 2013 to 2016 among men aged 60-69 years. Growth in both the older adult population and the rates of violence against this group, especially among men, suggests an important need for violence prevention strategies (3). Focusing prevention efforts for this population will require improved understanding of magnitude and trends in violence against older adults.

Emergency Department Visits for Sports- and Recreation-Related Traumatic Brain Injuries Among Children - United States, 2010-2016.

Traumatic brain injuries (TBIs), including concussions, are at the forefront of public concern about athletic injuries sustained by children. Caused by an impact to the head or body, a TBI can lead to emotional, physiologic, and cognitive sequelae in children (1). Physiologic factors (such as a child's developing nervous system and thinner cranial bones) might place children at increased risk for TBI (2,3). A previous study demonstrated that 70% of emergency department (ED) visits for sports- and recreation-related TBIs (SRR-TBIs) were among children (4). Because surveillance data can help develop prevention efforts, CDC analyzed data from the National Electronic Injury Surveillance System-All Injury Program (NEISS-AIP)* by examining SRR-TBI ED visits during 2010-2016. An average of 283,000 children aged <18 years sought care in EDs each year for SRR-TBIs, with overall rates leveling off in recent years. The highest rates were among males and children aged 10-14 and 15-17 years. TBIs sustained in contact sports accounted for approximately 45% of all SRR-TBI ED visits. Activities associated with the highest number of ED visits were football, bicycling, basketball, playground activities, and soccer. Limiting player-to-player contact and rule changes that reduce risk for collisions are critical to preventing TBI in contact and limited-contact sports. If a TBI does occur, effective diagnosis and management can promote positive health outcomes among children.

US campus fraternities and sororities and the young adult injury burden.

OBJECTIVE: To investigate whether the presence of fraternities and sororities was associated with a higher local injury rate among undergraduate-age youth. METHODS: In 2016 we compared the rate of 2010-2013 youth (18-24 years) emergency department (ED) visits for injuries in Hospital Service Areas (HSA) with and without fraternities and sororities. ED visits were identified in the State Emergency Department Database (n=1,560 hospitals, 1,080 HSAs, 16 states). US Census Bureau and National Center for Education Statistics sources identified HSA population and campus (n=659) characteristics. A proprietary database identified campuses with fraternities and sororities (n=287). ED visits explicitly linked to fraternities and sororities in the National Electronic Injury Surveillance System-All Injury Program were used to identify injury causes for sub-group analysis. RESULTS: HSAs serving campuses with fraternities and sororities had lower age 18-24 injury rates for all causes except firearm injuries (no difference). CONCLUSIONS: Fraternities and sororities were not associated with a higher injury rate at the population level among undergraduate-age youth. A major limitation is not being able to observe campus health services utilization.

Nonfatal Assaults Among Persons Aged 10-24 Years - United States, 2001-2015.

In 2015, persons aged 10-24 years who were treated for nonfatal assault injuries in emergency departments (EDs) in the United States accounted for 32% of the approximately 1.5 million patients of all ages that EDs treated for nonfatal assault injuries (1). CDC analyzed data from the National Electronic Injury Surveillance System-All Injury Program (NEISS-AIP) to examine 2001-2015 trends in nonfatal assault injuries among youths treated in EDs, by sex and age group, and to assess current rates by sex, age group, mechanism of injury, and disposition (1). Rates for 2001-2015 were significantly higher among males than among females and among young adults aged 20-24 years than among youths aged 10-14 and 15-19 years. During 2011-2015, rates declined for all groups. The 2015 rate among persons aged 10-24 years was 753.2 per 100,000 population, the lowest in the 15-year study period. Despite encouraging trends, the assault rate among young persons remains high. Rates in 2015 were higher among males, persons aged 20-24 years, and those who incurred intentional strike or hit injuries. Nearly one in 10 patients were admitted to the hospital, transferred to another hospital, or held for observation. Youth violence prevention strategies, including primary prevention approaches that build individual skills, strengthen family relationships, or connect young persons treated in EDs to immediate and ongoing support, can be implemented to decrease injuries and fatalities (2).

Suicide Trends Among and Within Urbanization Levels by Sex, Race/Ethnicity, Age Group, and Mechanism of Death - United States, 2001-2015.

PROBLEM/CONDITION: Suicide is a public health problem and one of the top 10 leading causes of death in the United States. Substantial geographic variations in suicide rates exist, with suicides in rural areas occurring at much higher rates than those occurring in more urban areas. Understanding demographic trends and mechanisms of death among and within urbanization levels is important to developing and targeting future prevention efforts. REPORTING PERIOD: 2001-2015. DESCRIPTION OF SYSTEM: Mortality data from the National Vital Statistics System (NVSS) include demographic, geographic, and cause of death information derived from death certificates filed in the 50 states and the District of Columbia. NVSS was used to identify suicide deaths, defined by International Classification of Diseases, 10th Revision (ICD-10) underlying cause of death codes X60-X84, Y87.0, and U03. This report examines annual county level trends in suicide rates during 2001-2015 among and within urbanization levels by select demographics and mechanisms of death. Counties were collapsed into three urbanization levels using the 2006 National Center for Health Statistics classification scheme. RESULTS: Suicide rates increased across the three urbanization levels, with higher rates in nonmetropolitan/rural counties than in medium/small or large metropolitan counties. Each urbanization level experienced substantial annual rate changes at different times during the study period. Across urbanization levels, suicide rates were consistently highest for men and non-Hispanic American Indian/Alaska Natives compared with rates for women and other racial/ethnic groups; however, rates were highest for non-Hispanic whites in more metropolitan counties. Trends indicate that suicide rates for non-Hispanic blacks were lowest in nonmetropolitan/rural counties and highest in more urban counties. Increases in suicide rates occurred for all age groups across urbanization levels, with the highest rates for persons aged 35-64 years. For mechanism of death, greater increases in rates of suicide by firearms and hanging/suffocation occurred across all urbanization levels; rates of suicide by firearms in nonmetropolitan/rural counties were almost two times that of rates in larger metropolitan counties. INTERPRETATION: Suicide rates in nonmetropolitan/rural counties are consistently higher than suicide rates in metropolitan counties. These trends also are observed by sex, race/ethnicity, age group, and mechanism of death. PUBLIC HEALTH ACTION: Interventions to prevent suicides should be ongoing, particularly in rural areas. Comprehensive suicide prevention efforts might include leveraging protective factors and providing innovative prevention strategies that increase access to health care and mental health care in rural communities. In addition, distribution of socioeconomic factors varies in different communities and needs to be better understood in the context of suicide prevention.

Childhood Firearm Injuries in the United States.

OBJECTIVES: Examine fatal and nonfatal firearm injuries among children aged 0 to 17 in the United States, including intent, demographic characteristics, trends, state-level patterns, and circumstances. METHODS: Fatal injuries were examined by using data from the National Vital Statistics System and nonfatal injuries by using data from the National Electronic Injury Surveillance System. Trends from 2002 to 2014 were tested using joinpoint regression analyses. Incident characteristics and circumstances were examined by using data from the National Violent Death Reporting System. RESULTS: Nearly 1300 children die and 5790 are treated for gunshot wounds each year. Boys, older children, and minorities are disproportionately affected. Although unintentional firearm deaths among children declined from 2002 to 2014 and firearm homicides declined from 2007 to 2014, firearm suicides decreased between 2002 and 2007 and then showed a significant upward trend from 2007 to 2014. Rates of firearm homicide among children are higher in many Southern states and parts of the Midwest relative to other parts of the country. Firearm suicides are more dispersed across the United States with some of the highest rates occurring in Western states. Firearm homicides of younger children often occurred in multivictim events and involved intimate partner or family conflict; older children more often died in the context of crime and violence. Firearm suicides were often precipitated by situational and relationship problems. The shooter playing with a gun was the most common circumstance surrounding unintentional firearm deaths of both younger and older children. CONCLUSIONS: Firearm injuries are an important public health problem, contributing substantially to premature death and disability of children. Understanding their nature and impact is a first step toward prevention.

Nonfatal Playground-Related Traumatic Brain Injuries Among Children, 2001-2013.

OBJECTIVE: To describe the circumstances, characteristics, and trends of emergency department (ED) visits for nonfatal, playground-related traumatic brain injury (TBI) among persons aged ≤14 years. METHODS: The National Electronic Injury Surveillance System-All Injury Program from January 1, 2001, through December 31, 2013, was examined. US Census bridged-race population estimates were used as the denominator to compute rates per 100 000 population. SAS and Joinpoint linear weighted regression analyses were used to analyze the best-fitting join-point and the annual modeled rate change. These models were used to indicate the magnitude and direction of rate trends for each segment or period. RESULTS: During the study period, an annual average of 21 101 persons aged ≤14 years were treated in EDs for playground-related TBI. The ED visit rate for boys was 39.7 per 100 000 and 53.5 for persons aged 5-9 years. Overall, 95.6% were treated and released, 33.5% occurred at places of recreation or sports, and 32.5% occurred at school. Monkey bars or playground gyms (28.3%) and swings (28.1%) were the most frequently associated with TBI, but equipment involvement varied by age group. The annual rate of TBI ED visits increased significantly from 2005 to 2013 (P < .05). CONCLUSIONS: Playgrounds remain an important location of injury risk to children. Strategies to reduce the incidence and severity of playground-related TBIs are needed. These may include improved adult supervision, methods to reduce child risk behavior, regular equipment maintenance, and improvements in playground surfaces and environments.

Firearm injuries in the United States.

OBJECTIVE: This paper examines the epidemiology of fatal and nonfatal firearm violence in the United States. Trends over two decades in homicide, assault, self-directed and unintentional firearm injuries are described along with current demographic characteristics of victimization and health impact. METHOD: Fatal firearm injury data were obtained from the National Vital Statistics System (NVSS). Nonfatal firearm injury data were obtained from the National Electronic Injury Surveillance System (NEISS). Trends were tested using Joinpoint regression analyses. CDC Cost of Injury modules were used to estimate costs associated with firearm deaths and injuries. RESULTS: More than 32,000 persons die and over 67,000 persons are injured by firearms each year. Case fatality rates are highest for self-harm related firearm injuries, followed by assault-related injuries. Males, racial/ethnic minority populations, and young Americans (with the exception of firearm suicide) are disproportionately affected. The severity of such injuries is distributed relatively evenly across outcomes from outpatient treatment to hospitalization to death. Firearm injuries result in over $48 billion in medical and work loss costs annually, particularly fatal firearm injuries. From 1993 to 1999, rates of firearm violence declined significantly. Declines were seen in both fatal and nonfatal firearm violence and across all types of intent. While unintentional firearm deaths continued to decline from 2000 to 2012, firearm suicides increased and nonfatal firearm assaults increased to their highest level since 1995. CONCLUSION: Firearm injuries are an important public health problem in the United States, contributing substantially each year to premature death, illness, and disability. Understanding the nature and impact of the problem is only a first step toward preventing firearm violence. A science-driven approach to understand risk and protective factors and identify effective solutions is key to achieving measurable reductions in firearm violence.
