DESIGN. We performed a retrospective analysis of data from the US Consumer Product Safety Commission's National Electronic Injury Surveillance System from 19902003.
RESULTS. An estimated 85800 pediatric fireworks-related injuries were treated in US emergency departments during the 14-year study period. Injured children had a mean age of 10.8 years, and 77.9% were male. Fireworks users accounted for 49.5% of the injuries, whereas 22.2% of the injuries were to bystanders; however, user status could not be determined in 28.3% of cases. The overall fireworks-related injury rate decreased significantly during the study period, but subgroup analysis did not indicate consistent declines among all ages and types of fireworks. Injuries were most commonly caused by firecrackers (29.6%), sparklers/novelty devices (20.5%), and aerial devices (17.6%). The most commonly injured body sites were the eyeball (20.8%), face (20.0%), and hands (19.8%), and the most common injury type was burns (60.3%). Approximately 91.6% of all children with fireworks-related injuries were treated and released from hospital emergency departments, 5.3% were admitted, and 2.3% were transferred to another institution. Bystanders accounted for 13.3% of admitted cases and 20.6% of transferred cases.
CONCLUSIONS. Consumer fireworks cause serious preventable injuries among pediatric fireworks users and bystanders in the United States. Parents should be advised to take their children to safer public fireworks displays rather than allowing consumer fireworks to be used by or near their children. A national restriction of consumer fireworks, in accordance with the policy recommendations of the American Academy of Pediatrics, should be implemented to reduce the burden of fireworks-related injuries among children.

Every year, Americans celebrate the Fourth of July by setting off firecrackers, bottle rockets, sparklers, and other consumer fireworks, and every year, fireworks cause serious injuries to both users and bystanders. During the 2004 fireworks season, an estimated 9600 people sought emergency department (ED) care for fireworks-related injuries.1,2 Approximately 40% of these fireworks-related injuries occurred among children younger than 15 years.1,2 Parents often falsely assume that close supervision of children using fireworks3 and the use of safe and sane fireworks3,4 will prevent injuries. However, previous studies have found that parental supervision was present in 54% of fireworks-related injury events.3,4 In addition, sparklers, considered by some as one of the safer types of fireworks, have been found to cause 10% to 17% of fireworks-related injuries.46
Most data on fireworks-related injuries have been presented in governmental reports1,2,79 and short policy statements.4 Many of these are limited to the period surrounding the Fourth of July.1,79 Peer-reviewed publications tend to report aggregate results, including both adults and children,5,6,10 or to focus on specific types of injuries such as hand11 or ocular injuries.1214 Other studies have been retrospective analyses of data from individual EDs.3,10,11 Although several studies have been conducted outside of the United States,6,12,1416 it is difficult to compare results from such studies to US data because of the variability in countries' fireworks use and regulations.
Our objective with this study was to describe the epidemiology of US pediatric fireworks-related injuries by using a nationally representative database.

Variables
Firework Type
Each year, the CPSC conducts a fireworks study during the period surrounding the Fourth of July holiday (June 22 to July 22).1,7 Firework types, abstracted from NEISS narratives, were identified by using the classification system of previous CPSC fireworks studies.19,20 Firework types were then grouped into the following categories: firecrackers, aerial devices, Roman candles/fountains, sparklers/novelty devices, illegal fireworks, and other/unknown. Illegal fireworks consisted of large firecrackers, including M80s, M100s, and cherry bombs, as well as homemade devices. Firecrackers of an unknown size were included in the firecracker category rather than the illegal fireworks or other/unknown categories. Cases related to public displays (43 unweighted cases [1.8% of the original sample]) were excluded from analysis.
Body Site and Diagnosis
Injured body parts were grouped into the following categories: head/neck, face (including the mouth, nose, eyelids, and surrounding eye areas), upper extremities, lower extremities, trunk, 25% to 100% of the body (for burn injuries according to the NEISS coding manual),18 and other/unknown. In addition, hands, fingers, and eyeballs were kept as separate categories because of the frequency of their involvement and the clinical importance of injuries to these sites. Injury types were categorized as burns, contusions/abrasions, lacerations, entrance of a foreign body, and other/unknown.
Fireworks-User Status
A child was categorized as a fireworks user if the narrative specifically stated they were "playing with," handling, examining, or carrying fireworks or if the firework detonated in the child's hand. Children were categorized as bystanders if the narrative stated that someone else was the firework handler, the firework was thrown at or exploded near the child, the child stepped on or was hit by a firework that they were not handling, or if it was otherwise explicitly stated that the child was not the handler. All other cases were categorized as user status "uncertain."
Statistical Analysis
Data were analyzed by using SPSS 13.01 (SPSS Inc, Chicago, IL) and Stata 8.2 (Stata Corp, College Station, TX) statistical software. Statistical weights provided by the CPSC were used to calculate national injury estimates. Numbers reported in this article are national estimates unless noted otherwise. Rates of injury were calculated by using the 19902003 population estimates for 5-year age groups obtained from the US Census Bureau.21,22 Statistical analysis included the calculation of relative risks (RRs) with 95% confidence intervals (CIs), using stratum and primary sampling unit variables to account for the complex survey design of the NEISS sample. Trends over time were analyzed by using linear regression. The institutional review board of Columbus Childrens Research Institute approved this study.

Of all the children with fireworks-related injuries, 91.6% were treated and released from the hospital ED, 5.3% were admitted, 2.3% were transferred to another institution, and 0.8% resulted in other/unknown dispositions. Hospitalization was required for 14.4% of the children with illegal fireworks injuries, 5.3% of those with aerial device injuries, and 5.2% of those with firecracker injuries (Table 3). Illegal fireworks were more likely to result in hospitalization than all other fireworks types combined (RR: 3.35; 95% CI: 2.025.56). Among all hospitalized children with fireworks-related injuries, the hands (23.0%), face (18.6%), eyeball (15.8%), and lower extremities (15.0%) were the most common body sites injured. An estimated 6.1% of the children with aerial-device injuries were treated in the ED and then transferred to another institution (Table 3). When compared with all other fireworks categories combined, aerial-device injuries were more likely to result in transfer of the injured child (RR: 2.64; 95% CI: 1.315.31). Eyeball injuries made up a large proportion (40.2%) of the transferred cases.
Injuries to Users and Bystanders
Among the injured children, 49.5% were using fireworks, whereas 22.2% were bystanders (Table 1). User status could not be ascertained from the ED-chart narratives of the other 28.3% of cases (Table 1). Among bystanders, injuries were most often caused by firecrackers (25.6%), sparklers/novelty devices (24.0%), and aerial devices (13.0%) (Table 4). Fireworks users were also most frequently injured by firecrackers (31.9%), sparkler/novelty devices (21.2%), and aerial devices (14.1%) (Table 4). In 14.6% of sparkler injuries, the child stepped on a discarded sparkler. The most commonly injured body sites among bystanders were the lower extremities (25.5%), face (22.7%), and eyeball (22.5%), whereas the most commonly injured body sites among fireworks users were the hands (33.3%), fingers (18.6%), and eyeball (14.6%) (Table 4). Bystanders accounted for 13.3% of admissions (3.2% of bystanders), and fireworks users accounted for 66.9% of admissions (7.2% of users). Among transferred children, bystanders comprised 20.6% of the case subjects (2.4% of bystanders), and fireworks users comprised 34.3% of case subjects (1.8% of users).

Consistent with previous results, we found that fireworks-related injuries occur most frequently among boys1,5,7,16 and children 10 to 14 years of age.1,5,7,16 The largest proportion of injuries was caused by firecrackers2,3,5; the most frequently injured body sites were the face, hands, and eyeball2,4,5; and burns were the most common type of injury.1,3,5,7 In addition, our results showed that at least 20% of injured children were bystanders, which is comparable with earlier findings of Smith et al.3
Sparklers/novelty devices were associated with large proportions of injuries among children younger than 10 years, analogous to previous results.1,3,7 The prevalence of injuries from these types of fireworks among young children dispels the common misconception that these are "safe" fireworks that are appropriate for use by these children.4 Sparklers burn at temperatures >1000°F4; thus, it is not surprising that >70% of sparklers/novelty-device injuries were burns. Discarded sparklers also pose an injury risk to children, who can sustain burns or lacerations from stepping on sparkler wires.
In contrast with previous studies,5,13,23 we found that Roman candles/fountains, rather than aerial devices (specifically, bottle rockets), were responsible for a higher proportion of eye injuries. One explanation for this difference may be the categorization of body sites by the NEISS (ie, the area surrounding the eye is categorized as the face, whereas the eyeball is a separate entity).18 Most aerial-device injuries were to the face, possibly injuring the area surrounding the eye. Despite this discrepancy, aerial-device injuries were severe, responsible for
900 transfers to another hospital. These results confirm previous findings of the severity of aerial-device injuries3,5,1214 while indicating that previously ignored Roman candles/fountains are also sources of serious eye injuries.
The overall decline in fireworks-related injury rates found during this 14-year study period is consistent with CPSC reports,1,7 yet both our study and the CPSC reports indicate that rates have remained essentially unchanged after large declines before 1996.1,7 Furthermore, our results demonstrated that secular trends varied by age and firework type and were usually not significant. The cause of the overall decline in injury rates remains unclear, and the variability of subgroup-specific rates suggests that additional prevention efforts are needed to continue to decrease fireworks-related injury rates.
Nearly 19100 bystanders (22.2%) were injured by fireworks, sustaining injuries at vulnerable body sites such as the face and eyes. The consequences of these injuries can be severe, because they can result in reduced visual acuity and permanent blindness.13 In addition, bystanders accounted for substantial proportions of the admitted (13.3%) and transferred (20.6%) children, indicating the severity of injuries to bystanders. Sundelin and Norrsell14 found that there was no correlation between the seriousness of the injury and fireworks-user status. These results demonstrate that refraining from personal firework use does not protect against the risk of serious injury if merely being near anyone using fireworks places an individual at risk of injury.
Prevention and Policy
The results of this article, particularly in light of our findings regarding to injuries among bystanders, demonstrate the need for fireworks-related injury prevention throughout the United States. Prevention efforts for decreasing fireworks-related injury rates have traditionally fallen into 2 categories: (1) community education and intervention and (2) legislation or local ordinances restricting use and sales to private consumers. There have been few reports of evaluation of comprehensive intervention programs,14 although D'Argenio et al24 described a successful multifaceted intervention campaign during the New Year holiday season in Naples, Italy. However, its appropriateness for application within the United States is uncertain.
Some authors have suggested banning firecrackers and bottle rockets,5,10,12 often considered the most dangerous types of fireworks, as a means of injury prevention. Although this could eliminate many fireworks-related injuries, it clearly does not address the injuries caused by other currently legal fireworks such as Roman candles/fountains and sparklers/novelty devices. Despite claims by the American Pyrotechnics Association that fireworks-related injury rates are decreasing,25 the inconsistent declines in injuries over time demonstrated in this study and others1,5,7 show that more comprehensive prevention efforts are required across all subgroups of age and type of fireworks.
A more universal approach to injury prevention, especially for reducing bystander injuries, would be national restriction on all consumer fireworks sales and use. At the state level, Berger et al23 examined the effect of firework sales restrictions and found a significantly decreased rate of fireworks-related injury in states that restrict fireworks sales. A national ban on the sale and use of all consumer fireworks, in accordance with recommendations by the American Academy of Pediatrics4 and other national organizations,3,14 would allow for more consistent and effective regulation of fireworks. The National Fire Protection Association's model fireworks law, which bans all fireworks sales except toy paper caps for consumers other than professionals,26 has been implemented in several states as a means to regulate the sale of fireworks.26 The model law parallels the policy recommendations regarding fireworks use by the American Academy of Pediatrics4 and can serve as a guideline for a national fireworks-restriction plan (Table 5).

The fact that the limitations of this study mean our findings represent a conservative estimate of fireworks-related injuries should underscore the urgent need for prevention efforts. Few publications have described or evaluated interventions.24 Therefore, additional research is needed in this area. Examination of parental and societal attitudes toward fireworks use stands out as one direction for this type of research, because these attitudes are likely to affect the outcomes of implementing preventive interventions.
