Adverse drug events among outpatients that lead to emergency department visits are an important cause of morbidity in the United States, particularly among individuals aged 65 years or older. Ongoing, population-based surveillance can help monitor these events and target prevention strategies.

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.

Objective:To characterize sports and recreation related (SR) injury episodes in the US population. SR activities are growing in popularity suggesting the need for increased awareness of SR injuries as a public health concern for physically active persons of all ages in the US population.Setting:The National Health Interview Survey (NHIS) is a face-to-face household survey conducted yearly by the National Center for Health Statistics, part of the Centers for Disease Control and Prevention. Demographic and health data are collected from a nationally representative sample of the civilian, non-institutionalized population residing in the US.Methods:Medically attended injury events reported in the 1997–99 Injury Section of the NHIS were categorized according to the associated sport or recreational activity using a classification scheme based on the International Classification of External Causes of Injury system. Episodes where the injured person received any type of medical attention (that is, medical advice or treatment) from any health care provider were used to report the incidence, severity, and nature of SR injuries sustained by US citizens.Results:Annually, an estimated seven million Americans received medical attention for SR injuries (25.9 injury episodes per 1000 population). For 5–24 year olds, this national estimate was about 42% higher than estimates based on SR injuries seen only in emergency departments over a similar time frame. The highest average annual SR injury episode rates were for children ages 5–14 years (59.3 per 1000 persons) and persons aged 15–24 years (56.4 per 1000 persons). The SR injury episode rate for males was more than twice the rate for females. The age adjusted injury rate for whites was 1.5 times higher than for blacks (28.8v19.0 per 1000 population). Basketball was the most frequently mentioned SR activity when the injury episode occurred, with a rate of about four injury events per 1000 population. Strains and sprains accounted for 31% of injury episodes. An estimated 1.1 million SR episode related injuries involve the head or neck region, of which 17% were internal head injuries. The most common mechanisms of injury were struck by/against (34%), fall (28%), and overexertion (13%).Conclusion:As physical activity continues to be promoted as part of a healthy lifestyle, SR injuries are becoming an important public health concern for both children and adults. Prevention efforts aimed at reducing SR injuries through targeting high risk activities, places of occurrence, activity, risk behaviors, and use of protective devices need to go beyond focusing on children and also consider physically active adults.

Problem/Condition: Each year in the United States, an estimated one in six residents requires medical treatment for an injury, and an estimated one in 10 residents visits a hospital emergency department (ED) for treatment of a nonfatal injury. This report summarizes national data on fatal and nonfatal injuries in the United States for 2001, by age; sex; mechanism, intent, and type of injury; and other selected characteristics.
