ABSTRACT
| |
Objective To describe the incidence and circumstances of nonfatal firearm-related
injuries among children and adolescents treated in US emergency departments.
Design Data were obtained from the Firearm Injury Surveillance Study, 1993-1997;
data were collected through medical record review at hospitals participating
in the National Electronic Injury Surveillance System.
Setting The hospitals participating in National Electronic Injury Surveillance
System are a stratified probability sample of all US hospitals.
Main Outcome Measures Numbers and population rates for nonfatal firearm-related injuries among
children and adolescents younger than 20 years old.
Results An estimated 115 131 (95% confidence interval, 76 769-153 493)
children and adolescents were treated for a nonfatal gunshot wound during
the study period. The estimated annual rates of injury (per 100 000)
were 2.0 (children 0-4 years old), 2.2 (children 5-9 years old), 15.4 (children
10-14 years old), and 106.5 (adolescents 15-19 years old). The ratios of nonfatal
to fatal firearm-related injuries were 4.0 (children 0-4 years old), 4.4 (children
5-9 years old), 5.0 (children 10-14 years old), and 4.4 (adolescents 15-19
years old). An additional estimated 103 814 children (95% confidence
interval, 69 223-138 405) were shot with a nonpowder firearm (BB
or pellet gun). Boys 5 to 9 and 10 to 14 years old had the highest rates of
injury related to nonpowder firearms, an estimated 36.2 and 99.8 per 100 000,
respectively. Fifty-six percent of those 15 to 19 years old were assault victims.
An estimated 48% of children and adolescents with powder firearm–related
gunshot wounds and an estimated 4% with nonpowder firearm injuries were admitted
to the hospital.
Conclusions Nonfatal injuries related to powder firearms and nonpowder firearms
(BB or pellet guns) are an important source of injury among US children and
adolescents. Ongoing surveillance of nonfatal firearm-related injury among
children and adolescents is needed.
INTRODUCTION
THE RATE OF firearm deaths among US children far exceeds that in other
industrialized nations.1 Nonfatal firearm injuries
outnumber injury fatalities, however, information about them is limited.2, 3, 4 While the first comprehensive
national estimates of nonfatal firearm-related injuries reported in 1995 provided
much needed information, they provided limited details about injured children.5 Although firearm-related death rates appear to have
declined since the mid-1990s, they remain a common cause of injury death.6, 7 Because detailed national data are
lacking, we present national estimates, based on data from a representative
sample of US hospitals, on the number of children and adolescents with nonfatal
gun-related injuries treated in US emergency departments (EDs) over a 5-year
period.
MATERIALS AND METHODS
We obtained data from the Firearm Injury Surveillance Study, 1993-1997,
from the National Archive of Criminal Justice Data.8
Firearm Injury Surveillance Study, 1993-1997, data were collected at hospitals
participating in the National Electronic Injury Surveillance System (NEISS)
through an agreement between the Centers for Disease Control and Prevention
and the Consumer Product Safety Commission.5
The NEISS data have been used routinely by the Consumer Product Safety Commission
to monitor injuries related to consumer products, including nonpowder guns.9 Prior to June 1992, the Consumer Product Safety Commission
did not routinely collect data on injuries related to powder firearms.
The hospitals participating in NEISS are a stratified probability sample
of all US hospitals and includes children's hospitals. Data obtained from
these hospitals can be weighted to provide unbiased, statistically valid national
estimates of product-related injuries.9 The
sampling frame of NEISS was updated in 1997 to include 101 hospitals and a
stratum for children's hospitals; from 1993-1996 NEISS consisted of 91 hospitals.
An analysis of weighted data collected from both NEISS samples during an 8-month
overlap in 1997 indicated that differences in the national estimates of firearm-related
injuries were less than 1%, thus no statistical adjustments were made to adjust
for the sampling frame.7 Additional information
about the NEISS sample is available from us on request.
Gun-related injuries were defined as those cases in which a gun was
involved in the incident and included powder burns, pistol-whipping, recoil
injuries, and injuries sustained during cleaning of the weapon, as well as
penetrating gunshot wounds. Some of the gun-related injuries were from nonpowder
firearms (BB and pellet guns).5 Only those
who were alive at the time of discharge from the ED were counted.
Cases from each hospital were assigned a sample weight by NEISS; national
injury estimates were produced by summing the sample weights. The 95% confidence
intervals of these estimates were calculated based on SEs for firearms reported
by the Centers for Disease Control and Prevention.5, 7
National vital statistics data for 1993-1997 from the National Center for
Health Statistics were used to report firearm deaths.10
The US Census estimates for 1995, the median year of the sample, were used
to calculate age- and race-specific injury incidence rates.11
Race-specific rates are reported as white (non-Hispanic) and black; rates
for those of Hispanic ethnicity are also reported.
RESULTS
From January 1993 through December 1997 there were 6705 nonfatal gun-related
injuries to children and adolescents between 0 and 19 years old reported through
NEISS. Using the NEISS weightings, there were an estimated 244 822 injuries
(95% confidence interval, 172 844-316 800) in this age group treated
in US hospital EDs. Table 1 gives
the distribution of gunshot wounds and other injuries by weapon type (powder
or nonpowder firearm). Ninety percent of the injuries were the result of a
gunshot wound: the remaining 10% were other firearm-related injuries and included
being struck with a pistol or the butt of a gun, or being injured from weapon
recoil or from parts of the firearm during cleaning. Overall, nonpowder injuries
accounted for slightly less than half of the cases.

The estimated annual rates of powder firearm–related gunshot wounds
by age, sex, and race are listed in Table
2. The ratio of nonfatal to fatal firearm-related injuries ranged
from 4.0 to 5.0 across the age groupings. Rates of nonfatal powder firearm–related
gunshot wounds by age, sex, and race were calculated: among those younger
than 14 years, nonfatal powder firearm wound rates (per 100 000) were
5.8 (white males), 1.0 (white females), 10.8 (Hispanic males), 3.8 (Hispanic
females), 23.6 (black males), and 8.0 (black females). More specifically,
within the group of 10- to 14-year-old males, the rates of nonfatal powder
firearm–related gunshot wounds (per 100 000) were 14.6 for whites,
27.9 for Hispanics, and 60.8 for blacks; for males 15 to 19 years old the
rates (per 100 000) were 52.7 for whites, 307.4 for Hispanics, and 624.5
for blacks.

|
The highest annual rates of penetrating trauma from nonpowder firearms
(BB or pellet guns) were among males 10 to 14 years old, 99.8 per 100 000.
Males 5 to 9 years old had a rate of 36.2 per 100 000 and those 15 to
19 years old had a rate of 47.6 per 100 000. A comparison of the age-specific
rates among males of nonfatal gunshot wounds from powder firearms and from
nonpowder firearms is shown in Figure 1.
Rates of nonpowder firearm-related injuries increased with age among school-aged
boys, peaked in 13-year-olds, and declined thereafter. Powder firearm–related
gunshot wounds showed minor variation by year of age between the ages of 5
and 10 years old; between the ages of 11 and 18 years old the rates of nonfatal
injury increased by 50% to 100% for each year of age. The rates of powder
firearm–related wounds first exceeded rates of nonpowder firearm injuries
among 15-year-olds.

The circumstances of the injury, by age, for all firearm-related injuries
are given in Table 3. Among those
aged 14 years and younger, unintentional nonpowder firearm injuries were most
common; less than 10% were assaults. Of those with powder firearm injuries,
an estimated 47% were unintentional and an estimated 41% attributed to assaults
(data not shown in Table 3). Among
adolescents aged 15 to 19 years, an estimated 19% of powder firearm injuries
were unintentional and an estimated 66% were assaults. The proportions were
reversed for nonpowder firearm injuries: an estimated 64% of BB or pellet
gun injuries were unintentional and an estimated 15% were assaults (data not
shown in Table 3).

by Age, United States, 1993-1997*

In almost half of the cases, the shooter was not reported. In cases
for which this information was available, a minor fraction of the injuries
were the consequence of a shooting by a stranger: most wounds were self-inflicted
or inflicted by a relative or friend. The place where the injury occurred
was unknown in 47% of the cases (49% of the powder firearm cases, 45% of the
nonpowder firearm cases). Of cases for which the location of injury was known,
it was most often the home (31%, n = 76 549) or the street (12%, n =
28 542). School accounted for an estimated 1% (n = 2479) of firearm-related
injuries among those in this group, most of whom were of school age.
The primary body part affected by a gunshot wound with a powder firearm
was the leg or foot (37%, n = 42 619), upper trunk (17%, n = 19 339),
arm or hand (16%, n = 18 082), head or neck (15%, n = 17 381), or
lower trunk (14%, n = 15 890). The most common anatomical sites of injury
with nonpowder firearms were the head or neck (33%, n = 34 596), arm
or hand (30%, n = 31 202), and leg or foot (23%, n = 23 698). Nonpowder
firearms were associated with more wounds to the head or neck and arm or hand
than were powder firearms ( 2 test, P<.01
for each). An estimated 48% of children and adolescents with powder firearm–related
gunshot wounds were admitted to the hospital; 4% with injuries related to
nonpowder firearms were admitted to the hospital. Between 1993 and 1997, the
5 years of the study period, the annual estimated number of nonfatal firearm-related
injuries among children and adolescents aged 0 to 19 years declined from 57 047
(95% confidence interval, 34 573-79 521) in 1993 to 38 386
(95% confidence interval, 22 662-54 110) in 1997.
COMMENT
These data indicate that from 1993-1997 an estimated 800 children younger
than 10 years old were shot with a powder firearm each year, and an additional
5400 had some other firearm-related injury or were shot with a nonpowder firearm
(BB or pellet gun). Among those 10- to 14-years-old, an estimated 2900 had
gunshot wounds, and an estimated 11 600 were shot with a nonpowder firearm
or had some other powder firearm–related injury. Most of the injuries
were unintentional, and they occurred in the home disproportionately on the
weekend. Treating physicians did not consider the injuries trivial: almost
half of those with powder firearm–related injuries were admitted to
the hospital.
Prior national estimates of the number of nonfatal firearm-related injuries
among children are limited. Estimates from the first year of the Firearm Injury
Surveillance Study, 1993-1997, were published in 1995. In that analysis, the
2 age groupings that included children and adolescents were 0- to 14- and
15- to 24-year-olds. There were an estimated 3768 gunshot wounds among those
younger than 15 years.5
An analysis of firearm-related injuries in 3 American cities, Memphis,
Tenn; Seattle, Wash; and Galveston, Tex, from 1992 through 1994, showed rates
(per 100 000) for children 0 to 14 years old of 6.7 (white males), 16.4
(Hispanic males), 62.0 (black males), 4.7 (white females), 16.8 (Hispanic
females), and 27.5 (black females).3 As observed
in the 3 cities, the national estimates suggest nonfatal firearm-related injuries
disproportionately affect minority youth. It is not surprising the national
estimates of nonfatal firearm-related injuries are lower: firearm fatalities
have been observed to be higher in cities than in nonmetropolitan areas.12 Both local and national data about nonfatal firearm-related
injuries are needed. Local data aid in the evaluation of area-specific programs,
while national data allow us to recognize national trends and discuss national
priorities.
These data suggest that as gunshot wounds related to BB or pellet guns
among young teens declined, rates of gunshot wounds related to powder firearms
increased. This trend was observed among males in all race and ethnicity groups.
Others have reported injury rates related to nonpowder firearms to be highest
among 5- to 14-year-old males.13 Injuries related
to nonpowder firearms infrequently resulted in hospital admission. Case series
suggest that BB or pellet gun injuries can be serious.14, 15, 16
Because of several recent shootings in schools, public attention has
been focused on firearm violence there.17, 18, 19
These national data indicate that a small proportion of firearm injuries occur
at school. Although the actual estimates of the numbers of nonfatal firearm
injuries at school must be interpreted with caution because such low estimates
are unstable, it is clear that most firearm-related injuries among school-aged
children occur at home. While making schools safe havens from firearm violence
is essential, allocation of resources to prevent firearm-related injuries
must acknowledge the preponderance of injuries at home.
The distribution of injuries by anatomical area among those younger
than 20 years that we report was similar to that reported for firearm-related
gunshot wounds among all ages.5 Nonpowder firearms
were associated with more head or neck and upper extremity injuries.
An estimated 40% of injuries among both children younger than 15 years
and those 15 to 19 years old occurred on the weekend. This implies that firearms,
or time to use firearms, are more available to children and adolescents during
the weekend.
The NEISS has been observed to have several limitations for capturing
information on nonfatal firearm-related injuries. The estimates are imprecise,
as indicated by the wide confidence intervals. This also limits analysis of
groups stratified by race or sex. However, we observed that the average annual
incidence of firearm injury among children 0 to 14 years old, 3719, calculated
using data from 5 years (1993-1997), was similar to the estimate reported
for June 1992 through May 1993 (3768), implying year-to-year stability of
the estimates.5
Much of the imprecision results from variation in the number of gunshot
wound cases treated at NEISS sample hospitals, which is affected by the level
of care provided in the ED, the location of the hospital, and the patient
population that is served. Not all firearm-related injuries are brought to
medical attention and treated in the ED. While this would not affect the validity
of the estimates we present for children treated in the ED, it would result
in an underestimate of injuries.
Information about the circumstances of the injury incident was incomplete,
as some medical records were missing firearm type, location of the injury,
and the victim-shooter relationship. Therefore, we do not report the specific
type of powder firearm (handgun or long gun). We report location of injury
based on the available data. Despite incomplete data, it is useful to review
the available information about injury circumstances, as any detail about
the circumstances of injury among children is important for a better understanding
of these injuries.
There are many social and cultural barriers to protecting children from
firearms. It is clear that many children and young adolescents have ready
access to both powder and nonpowder firearms. Most injuries are unintentional,
and few are inflicted by strangers. It is essential that the burden of firearm-related
injury among youth be recognized and efforts made to decrease guns from the
environments of children and adolescents.

What This Study Adds
Information about the rates of nonfatal firearm-related injury among
children and adolescents is limited. National data suggest the ratio of nonfatal
to fatal firearm-related injuries is 2.6:1. This review of NEISS data (1993-1997)
suggests the rates (per 100 000) of nonfatal gunshot wound injuries ranged
from 2.0 (children 0-4 years old) to 106.5 (adolescents 15-19 years old).
The age group–specific ratios of nonfatal to fatal firearm-related injuries
were between 4.0 and 5.0. Nonfatal injuries related to firearms are an important
cause of injuries among youth; ongoing surveillance of nonfatal firearm-related
injuries is needed.
