Sports and recreation related injury episodes in the US population, 1997–99

Judith M. Conn; Joseph L. Annest; Julie Gilchrist

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 (28.8 v 19.0 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.

BACKGROUND Among the victims of floods, earthquakes, and hurricanes, there is an increased prevalence of post-traumatic stress disorder and depression, which are risk factors for suicidal thinking. We conducted this study to determine whether natural disasters affect suicide rates. METHODS From a list of all the events declared by the U.S. government to be federal disasters between 1982 and 1989, we selected the 377 counties that had each been affected by a single natural disaster during that period. We collected data on suicides during the 36 months before and the 48 months after the disaster and aligned the data around the month of the disaster. Pooled rates were calculated according to the type of disaster. Comparisons were made between the suicide rates before and those after disasters in the affected counties and in the entire United States. RESULTS Suicide rates increased in the four years after floods by 13.8 percent, from 12.1 to 13.8 per 100,000 (P<0.001), in the two years after hurricanes by 31.0 percent, from 12.0 to 15.7 per 100,000 (P<0.001), and in the first year after earthquakes by 62.9 percent, from 19.2 to 31.3 per 100,000 (P<0.001). The four-year increase of 19.7 percent after earthquakes was not statistically significant. Rates computed in a similar manner for the entire United States were stable. The increases in suicide rates were found for both sexes and for all age groups. The suicide rates did not change significantly after tornadoes or severe storms. CONCLUSIONS Our study shows that suicide rates increase after severe earthquakes, floods, and hurricanes and confirms the need for mental health support after severe disasters.

Kyran P. Quinlan; Joseph L. Annest; Barry S. Myers; George W. Ryan; Howard Hill

CONTEXT Motor vehicle (MV)-related injury is a leading cause of death and emergency department visits in the US. Information has been limited regarding the magnitude and types of injuries suffered by the survivors of MV crashes. OBJECTIVE To estimate the incidence and patterns of neck strain/sprain injury among MV occupants treated in US hospital emergency departments. DESIGN AND PARTICIPANTS Descriptive epidemiologic analysis of persons treated at a stratified, probability sample of US hospital emergency departments from 1 July to 31 December 2000. SETTING US. MAIN OUTCOME MEASURES Annualized national estimates of number and rate of neck strain/sprain injury among MV occupants overall and by patients age and sex. Rates were calculated per 100,000 population as well as per billion person miles traveled. RESULTS In 2000, an estimated 901,442 (95% CI 699,283-1,103,601) persons with neck strain/sprain injury were treated in US hospital emergency departments. For MV occupants, neck strain/sprain was the most frequent type of injury, comprising 27.8% of all injuries to MV occupants treated in emergency departments that year. The incidence (per 100,000 population) of neck strain/sprain was significantly lower in younger children and peaked in the 20-24-year age group. The incidence (per billion person miles traveled) peaked in the 15-19-year age group. Females tended to have a higher incidence of emergency department-treated neck strain/sprain than males. CONCLUSIONS Neck strain/sprain is the most common type of injury to MV occupants treated in US hospital emergency departments. Based on emergency department visits, these estimates suggest that the problem of neck injury may be larger than has been previously demonstrated using other surveillance tools. Further research is needed to determine contributory factors and prevention measures to reduce the risk of neck injury among MV occupants especially among those at higher risk such as females, older teenagers and young adults.

CDC’s National Violent Death Reporting System: background and methodology

Leonard J. Paulozzi; James A. Mercy; Lorraine Frazier; Joseph L. Annest

Objectives: This paper describes a new surveillance system called the National Violent Death Reporting System (NVDRS), initiated by the United States Centers for Disease Control and Prevention. NVDRS’s mission is the collection of detailed, timely information on all violent deaths. Design: NVDRS is a population based, active surveillance system designed to obtain a complete census of all resident and occurrent violent deaths. Each state collects information on its own deaths from death certificates, medical examiner/coroner files, law enforcement records, and crime laboratories. Deaths occurring in the same incident are linked. Over 270 data elements can be collected on each incident. Setting: The 13 state health departments of Alaska, Colorado, Georgia, Maryland, Massachusetts, New Jersey, North Carolina, Oklahoma, Oregon, Rhode Island, South Carolina, Virginia, and Wisconsin. Subjects: Cases consist of violent deaths from suicide, homicide, undetermined intent, legal intervention, and unintentional firearm injury. Information is collected on suspects as well as victims. Interventions: None. Outcome measures: The quality of surveillance will be measured in terms of its acceptability, accuracy, sensitivity, timeliness, utility, and cost. Results: The system has just been started. There are no results as yet. Conclusions: NVDRS has achieved enough support to begin data collection efforts in selected states. This system will need to overcome the significant barriers to such a large data collection effort. Its success depends on the use of its data to inform and assess violence prevention efforts. If successful, it will open a new chapter in the use of empirical information to guide public policy around violence in the United States.

Objective: To characterise and provide nationally representative estimates of persons with non-fatal horse related injuries treated in American emergency departments. Methods: The National Electronic Injury Surveillance System All Injury Program (NEISS–AIP) is a stratified probability sample comprising 66 hospitals. Data on injuries treated in these emergency departments are collected and reported. NEISS–AIP data on all types (horseback riding and otherwise) of non-fatal horse related injuries from 2001 to 2003 were analysed. Results: An estimated 102 904 persons with non-fatal horse related injuries (35.7 per 100 000 population) were treated in American emergency departments each year from 2001 to 2003 inclusive. Non-fatal injury rates were higher for females (41.5 per 100 000) than for males (29.8 per 100 000). Most patients were injured while mounted on a horse (66.1%), commonly from falling or being thrown by the horse; while not mounted, injuries most often resulted from being kicked by the horse. The body parts most often injured were the head/neck region (23.2%), lower extremity (22.2%), and upper extremity (21.5%). The most common principal diagnoses were contusions/abrasions (31.4%) and fractures (25.2%). For each year that was studied, an estimated 11 502 people sustained traumatic brain injuries from horse related incidents. Overall, more than 11% of those injured were admitted to hospital. Conclusions: Horse related injuries are a public health concern not just for riders but for anyone in close contact with horses. Prevention programmes should target horseback riders and horse caregivers to promote helmet use and educate participants about horse behaviour, proper handling of horses, and safe riding practices.

STUDY OBJECTIVE To characterize differences in the lethality of firearm-related injuries in selected demographic subgroups using national representative data on fatal and nonfatal firearm-related injuries. We also characterize the lethality of firearm-related injuries by intent of injury and anatomic location of the gunshot wound. METHODS We analyzed case-fatality rates (CFRs) of firearm-related injuries in the United States by using death data from the National Vital Statistics System and data on nonfatal injuries treated in US hospital emergency departments from the National Electronic Injury Surveillance System. National estimates of crude and age-adjusted CFRs are presented by sex, race/ethnicity, age, intent, and primary body part affected. RESULTS Each year during the study period (July 1992 through December 1995), an estimated 132,687 persons sustained gunshot wounds that resulted in death or treatment in an ED. The overall age-adjusted CFR among persons who sustained firearm-related injuries was 31.7% (95% confidence interval [CI] 27.7 to 35.6). The age-adjusted CFR for persons who were alive when they arrived for treatment in an ED (11. 3%; 95% CI 9.4 to 13.2) was about one third as large as the overall CFR. The age-adjusted CFR varied by sex, race/ethnicity, and age, but these differences depended on intent of injury. For assaultive injuries, the age-adjusted CFR was 1.4 times higher for females (28. 7%) than males (20.6%). For intentionally self-inflicted injuries, the age-adjusted CFR was 1.1 higher for males (77.7%) than females (69.1%). For assaults, the age-adjusted CFR was 1.5 times higher for whites (29.5%) than blacks (19.2%). For assaultive and intentionally self-inflicted injuries among persons 15 years and older, the age-specific CFR increased with age. Persons shot in the head (age-adjusted CFR, 61.0%) were 3.3 times as likely to die as those shot in other body parts (age-adjusted CFR, 18.7%). CONCLUSION The lethality of firearm-related injuries was influenced strongly by the intent of injury and body part affected. The high lethality of firearm-related injuries relative to other major causes of injury emphasizes the need to continue prevention efforts and efforts to improve access to care and treatment (including emergency medical and acute care services) to reduce the number and increase survivability of firearm-related injuries.

STUDY OBJECTIVE Injury is a major cause of morbidity and mortality in the United States. Although the National Vital Statistics System provides data on injury-related deaths, a national surveillance system is needed for timely identification of emerging nonfatal injury problems and continuous monitoring of severe nonfatal injuries. This work assesses the feasibility of expanding the National Electronic Injury Surveillance System (NEISS) to monitor all types and causes of nonfatal injuries treated in US hospital emergency departments and reports national estimates generated by a pilot study of this system. METHODS At a stratified sample of US hospital EDs, persons receiving first-time treatment for an injury were monitored from May 1 through July 31, 1997. National estimates of the annual number and rate of ED-treated injuries overall, by patient characteristics, injury diagnosis, and external cause of injury were generated, and the sensitivity of the system for detecting ED-treated injuries was assessed. RESULTS An estimated 29. 1 million injuries were treated in US EDs in 1997 (rate of 108.6/1, 000 population). The leading causes of injury were falls, being struck by or striking against an object or person, cutting or piercing, and motor vehicle traffic. Of 593 cases of injury detected by investigators from the Centers for Disease Control and Prevention during visits to 6 of the 21 NEISS hospitals in the study, 490 were also detected by NEISS coders for an overall sensitivity of 82.6%. CONCLUSION Expanding the NEISS is a feasible means of timely and continuous monitoring of all types and causes of nonfatal injuries treated in US hospital EDs.

Trends in Nonfatal and Fatal Firearm-Related Injury Rates in the United States, 1985–1995☆☆☆★

Darci Cherry; Joseph L. Annest; James A. Mercy; Marcie-jo Kresnow; Daniel A. Pollock

STUDY OBJECTIVE To characterize trends in annual estimates of nonfatal firearm-related injuries treated in US hospital emergency departments and to compare trends in quarterly rates of such injuries with those of firearm-related fatalities in the US population. METHODS Data on nonfatal firearm-related injuries were obtained from the National Electronic Injury Surveillance System (NEISS) by review of medical records for June 1, 1992, through May 31, 1995. Data on firearm-related fatalities were obtained from the National Vital Statistics System for January 1, 1985, through December 31, 1995. NEISS comprises 91 hospitals that represent a stratified probability sample of all hospitals in the United States and its territories that have at least six beds and provide 24-hour emergency service. The main outcome measures were numbers, percentages, and quarterly population rates for nonfatal and fatal firearm-related injuries. RESULTS An estimated 288,538 nonfatal firearm-related injuries (95% confidence interval [CI], 169,776 to 407,300) were treated in EDs during the 3-year study period. The annual number of non-fatal firearm-related injuries increased from 99,025 for June 1992 through May 1993 (95% CI, 58,266 to 139,784) to 101,669 for June 1993 through May 1994 (95% CI, 59,822 to 143,516), then decreased to 87,844 for June 1994 through May 1995 (95% CI, 51,687 to 124,001). Before the third quarter of 1993, quarterly nonfatal and fatal firearm-related injury rates in the total US population and quarterly nonfatal firearm assaultive injury and firearm homicide rates for males aged 15 to 24 years were observed to be on the rise. Since then, these rates have significantly declined. CONCLUSION Analysis of national trends indicates that non-fatal and fatal firearm-related injuries are declining in the United States, although the rate of firearm-related deaths remains high, especially among males aged 15 to 24 years, in relation to other leading causes of injury death. An assessment of factors responsible for the decline in firearm-related injuries is needed to design further prevention efforts.

Firearm injuries in the United States.

Katherine A. Fowler; Linda L. Dahlberg; Tadesse Haileyesus; Joseph L. Annest

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

The Ongoing Hazard of BB and Pellet Gun-Related Injuries in the United States

Ann Marie McNeill; Joseph L. Annest

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.
