Abstract
OBJECTIVE: To investigate the epidemiology of television (TV)-related injuries to children in the United States.
METHODS: Using data from the National Electronic Injury Surveillance System, children aged <18 years treated in United States hospital emergency departments for an injury associated with a TV from 1990 through 2011 were investigated.
RESULTS: An estimated 380 885 patients aged <18 years were treated in emergency departments for a TV-related injury during the 22-year study period, which equals an annual average of 17 313 children. The median age of patients was 3 years; children <5 years represented 64.3% of patients, and boys comprised 60.8%. The average annual injury rate was 2.43 (95% confidence interval [CI]: 2.07–2.80) injuries per 10 000 children aged <18 years, with a range of 2.15 (95% CI: 1.64–2.66) to 2.90 (95% CI: 2.31–3.49). Although the overall injury rate was steady, the number and rate of injuries associated with falling TVs increased significantly by 125.5% and 95.3%, respectively, during the study period. In addition, there was a significant 344.1% increase in the number of injuries associated with a TV falling from a dresser/bureau/chest of drawers/armoire during 1995–2011.
CONCLUSIONS: The rate of pediatric injuries caused by falling TVs is increasing, which underscores the need for increased prevention efforts. Prevention strategies include public education, provision of TV anchoring devices at the point of sale of TVs, TV anchoring device distribution programs, strengthening of standards for TV stability, and redesign of TVs to improve stability.

What’s Known on This Subject:
Previous research has demonstrated that pediatric injuries associated with television (TV) tip-overs are increasing, children aged ≤4 years are at highest risk for injury, and the head and neck are most commonly injured.
What This Study Adds:
We analyzed a nationally representative sample comprising 22 years of data. On average, 17 313 children receive emergency treatment of a TV-related injury annually in the United States. The rate of injury attributable to falling TVs increased by 95% over 22 years.
Televisions (TVs) are omnipresent; 99% of American households own ≥1 TV set, and 55% possess ≥3.1 During the 2010–2011 TV season, children aged 2 through 11 watched nearly 26 hours of TV weekly.1 The frequent exposure to TVs presents opportunities for children to sustain TV-related injury. Between 2000 and 2011, 215 children died of injuries sustained from a falling TV.2 Despite previous studies identifying the risks of TV tip-over injuries, newspaper articles highlighting local tragedies,3–6 and the US Consumer Product Safety Commission (CPSC) listing TV and furniture tip-overs third in their top 5 hidden hazards,7 safety standards for TV stability do not include the requirement that TVs be sold with antitip or anchoring devices, although this requirement exists for certain types of large furniture.8,9
Previous studies implicate furniture and TV tip-overs as causes of serious injury and find the incidence of TV-related injury to be increasing,10–14 but many of the studies were published years ago.12,15,16 Most earlier studies were retrospective case reports,10,12–14,16–20 providing descriptive analysis and focusing on the serious neurologic sequelae resulting from a TV tip-over.21–25 Previous research finds the highest incidence of injury among the 1- to 4-year-old age group and the head most commonly injured.10,12–15,18–20 Studies using data from the National Electronic Injury Surveillance System (NEISS) evaluated fewer years and conducted less in-depth analyses than the current study.16,26
This study examines trends of pediatric TV-related injuries by using a nationally representative data set over a 22-year period. It provides a discussion of relevant injury prevention strategies.
Methods
This study analyzed data for children aged <18 years who were treated in hospital emergency departments (EDs) for a TV-related injury from January 1, 1990, through December 31, 2011. Data were obtained from the NEISS, a surveillance system maintained by the US CPSC that monitors ∼100 EDs. These participating EDs represent a stratified probability sample of the >5000 hospital EDs providing 24-hour care with ≥6 beds in the United States and its territories.27
TV-related injuries were identified by using NEISS consumer product codes 0572 (TVs) and 0519 (TV tables or stands). Variables in the data set include age, gender, injury diagnosis, injured body region, product(s) involved, locale of injury, disposition from the ED, and a short narrative regarding the circumstances of the incident. Professional NEISS coders input data daily into the NEISS database extracted from patient ED medical records in participating hospitals.
The narrative text of each case was reviewed for potential miscoding and to classify the mechanism of injury into the categories of (1) TV falls, (2) patient strikes TV, (3) injury occurs while moving TV, and (4) other. In instances of multiple mechanisms of injury, a decision rule based on the likely causal sequence was used; “moving TV” took precedence over “TV falls,” which took precedence over “strikes TV.” Some case narratives listed the furniture on which the TV rested, and this information was used to create a variable with the categories of (1) dresser/bureau/chest of drawers/armoire, (2) entertainment center/TV stand, (3) shelf/rack, (4) table/nightstand, (5) cart, (6) cabinet/counter/changing table, (7) wall mount, and (8) other, which included bed, chair, toy box, and other furniture not designed to support a TV. Some case narratives also included information about the screen size of the TV, which was used to create a variable with the 2 categories of (1) TV ≤26 inches and (2) TV ≥27 inches. NEISS injury diagnosis codes were condensed into 6 groups: (1) laceration (including amputation, puncture and avulsion), (2) concussion/closed head injury (including internal injury to the head), (3) soft tissue injury (including hematoma, crush injury, contusion and abrasion), (4) fracture, (5) strain/sprain, and (6) other. The “other” category included foreign object injury, burn, dental injury, electrical shock, and dislocation. NEISS body region codes were grouped into 5 categories: (1) head/neck, (2) upper extremity (including shoulder), (3) lower extremity, (4) torso (including pubic region), and (5) multiple body regions. Cases were excluded from this study if the primary reason for the ED visit was not a TV-related injury or if the injury was not directly related to a TV: for example, if the injury was associated with the furniture a TV was resting on, but not the TV itself; a cable box outdoors; ingestion of a remote control battery; or jumping off the TV. National estimates in this study were based on weighted data from 12 227 patients meeting inclusion criteria. Numbers presented in this article are weighted estimates unless otherwise stated.
Data were analyzed by using SPSS 19.0 (SPSS Inc, Chicago, IL) and SAS Version 9.3 (SAS Institute Inc, Cary, NC). Ninety-five percent confidence intervals (CIs) were calculated for national estimates. Sample weights provided by the CPSC and annual population estimates from the US Census Bureau were used to calculate national injury frequency and rate estimates.28–30 Weighted linear regression with weights equal to the inverse of the variance of each estimated statistic was performed to evaluate secular trends for TV-related injuries during the study period. Statistical assessment included χ2 analysis with Yates’s correction and calculation of relative risks with corresponding 95% CIs. Statistically significant relationships were determined by α = .05. Estimates based on ≤20 unweighted cases are considered to be unstable by the CPSC and were excluded from analyses. This study was approved by the institutional review board of the author’s institution.
Results
Overall Trends and Demographics
An estimated 380 885 (95% CI: 322 630–439 141) pediatric patients were treated in US EDs for TV-related injuries during the 22-year study period, equaling an annual average of 17 313 (95% CI: 14 665–19 961) children. The injury rate remained consistent during the study period (m = –0.01, P = .081), with an annual average of 2.43 (95% CI: 2.07–2.80) injuries per 10 000 children ≤17 years of age and ranging from 2.15 (95% CI: 1.64–2.66) to 2.90 (95% CI: 2.31–3.49) injuries per 10 000 (Fig 1). The mean patient age was 4.7 (95% CI: 4.59–4.87) years, with a median age of 2.7 (95% CI: 2.67–2.77) years. Children <5 years of age represented 64.3% of injured patients, followed by children 5 through 10 years of age (24.3%), and 11 through 17 years of age (11.4%; Table 1). Two-year-olds were the age group most commonly injured by TVs (19.0%). Injuries among male patients predominated, comprising 60.8% of the total (Fig 2). Among the 79.4% of cases with locale of injury documented, 98.1% occurred in the home.

Mechanism of Injury and Body Region Injured
The most common mechanism of injury was a TV falling and hitting the patient (52.5%), followed by the patient striking a TV (38.1%; Table 1). In contrast to steady overall injury rates during the study period, the rate of injury associated with falling TVs increased significantly (m = 0.05, P < .001) by 95.3%, from 0.85 (95% CI: 0.52–1.18) injuries per 10 000 children ≤17 years in 1990 to 1.66 (95% CI: 1.17–2.16) injuries per 10 000 children in 2011 (Fig 3). This corresponded to a 125.5% (m = 400.8, P < .001) increase in number of injuries associated with falling TVs from 5455 (95% CI: 3347–7562) in 1990 to 12 300 (95% CI: 8623–15 976) in 2011. The rate of injury from striking a TV decreased significantly (m = –0.06, P < .001) by 71.9%, from 1.53 (95% CI: 1.06–2.01) injuries per 10 000 children in 1990 to 0.43 (95% CI: 0.28–0.57) injuries per 10 000 in 2011 (Fig 3). This corresponded to a 68.0% decrease in the number of injuries associated with striking a TV (m = –344.1, P < .001) from 9835 (95% CI: 6791–12 880) in 1990 to 3143 (95% CI: 2096–4190) in 2011.

The head and neck region was the most common body region injured (63.3%), followed by the lower extremities (21.5%; Table 1). When compared with other body regions, head and neck injury was 1.36 (95% CI: 1.03–1.80) times more likely to result in hospital admission. Compared with other age groups, children <5 years of age were 1.36 (95% CI: 1.30–1.42) times more likely to injure their head and neck and 1.22 (95% CI: 1.15–1.32) times more likely to be injured by a falling TV. A falling TV was 3.28 (95% CI: 2.84–3.81) times more likely than other injury mechanisms to cause a lower extremity injury.
Injury Diagnosis
Lacerations and soft tissue injuries predominated, accounting for 36.7% and 35.1% of injuries, respectively (Table 1). Concussions and closed head injuries represented 13.3% of injuries among children <5 years and 7.7% of injuries among patients 11 through 17 years of age (Table 1). TV falls, compared with other mechanisms of injury, were 3.04 (95% CI: 2.55–3.62) times more likely to lead to a diagnosis of concussion, and 2.18 (95% CI: 1.98–3.40) times more likely to cause a soft tissue injury.
Disposition From the ED
Only 2.6% of patients receiving emergency treatment of TV-related injuries required admission to the hospital or <24-hour observation (Table 1). Children <5 years of age, when compared with patients aged 5 to 17 years, were 1.84 (95% CI: 1.38–2.44) times more likely to be admitted to the hospital. TV fall–related injuries, compared with injuries associated with other mechanisms, were 4.31 (95% CI: 2.94–6.30) times more likely to require hospital admission.
Placement and Size of TVs
Among injury cases associated with falling TVs, the furniture on which the TV rested was noted in 30.5% of cases, and the size of the TV was recorded in 19.0% of cases (Table 2). When documented, the most common type of furniture was a dresser/bureau/chest of drawers/armoire, representing 46.0% of these cases, followed by TV stands and entertainment centers (31.3%). The number of documented injuries associated with a TV falling from a dresser/bureau/chest of drawers/armoire increased significantly (m = 93.3, P < .001) by 344.1%, from 632 (95% CI: 367–895) in 1995 to 2807 (95% CI: 1808–3805) in 2011. During 1996–2011, there is no significant change (m = 5.4, P = .754) in the number of documented injuries resulting from a TV falling off TV stands and entertainment centers. When TV size was documented, TVs ≤26 inches were involved in 66.8% of these cases. There was no significant trend (m = 13.3, P = .075) in the number of documented injuries associated with a falling TV with a screen size of ≤26 inches during the period 1992–2011. There was also no significant trend (m = 10.7, P = .468) in the number of documented injuries associated with a falling TV with a screen size of ≥27 inches during the period 2000–2011.
Furniture Type and TV Sizes Reported for Injuries Associated With Falling TVs
Discussion
More than 17 000 children receive emergency treatment of a TV-related injury in the US annually, which equals 1 child every 30 minutes. Although the overall rate of TV-related injury stayed fairly constant, the rate of injury associated with a falling TV almost doubled during the study period.
The number of US households with multiple TVs has more than doubled since 1990; now more than half of US households own ≥3 TVs. The escalating rate of injury from falling TVs may be due to the rising number of TVs in the home; however, if this were the only reason, then injury associated with striking the TV should also have increased due to increased exposure, but we found the opposite to be true.
The disparity between injury rates associated with falling TVs and striking a TV is provocative, especially given the more serious outcomes associated with falling TVs, and we speculate that changes in the location of TV placement in the home may be responsible for these observed trends. Sales of cathode ray tube (CRT) TVs have dropped steadily during recent years, with sales volume declining 84% in Europe from 2000 to 2010. In the United States, there have been negligible CRT TV sales in recent years, and based on an Internet search, many major electronics stores no longer carry CRT TVs.31,32 As consumers purchase newer flat-panel display TVs, the fate of older CRT TVs is relevant. Older TVs may be relegated to less safe locations in the home, such as on dressers or other unsuitable furniture. Although furniture companies have recalled unstable TV stands,33 dressers are often implicated in TV tip-overs.11,15 Despite the relatively low documentation in NEISS narratives of the type of furniture on which falling TVs were placed, the frequency of dressers/bureaus/chests of drawers/armoires being used to support TVs (almost half of the cases in this study) is alarming. Moreover, the number of documented injuries associated with a TV falling from a dresser/bureau/chest of drawers/armoire increased almost 3.5-fold in 1995–2011, while there was no significant change in the number of documented injuries resulting from a TV falling off TV stands and entertainment centers during 1996–2011. As noted in previous studies, children may pull dresser drawers open to use as stairs to help them reach the TV, potentially pulling both the dresser and TV over onto themselves.11 Small TVs do not preclude injury; approximately two-thirds of TVs with the screen size documented had a screen that was ≤26 inches. Safely positioning all TVs on appropriate furniture and securely anchoring both the TV and furniture, usually to the wall, is critical for the prevention of TV tip-over injuries.
The conversion to flat-screen TVs may also be contributing to the observed injury trends. CRT TVs carry their weight toward the screen, predisposing them to tip forward, and in 1 study, the weight of an anthropomorphic model of a 4-year-old child tipped 90% of TVs, emphasizing the potential for injury.24 Flat panel displays are 82% lighter than CRTs with a similar screen size. For example, 13- to 36-inch screen size CRTs weigh, on average, 80.9 pounds compared with an average of 14.8 pounds for flat panel displays of 16 to 37 inches.34 Lighter weights coupled with a less bulky design may make flat panels more easily tipped than CRTs and may be contributing to the observed increase in the rate of injuries associated with falling TVs. Additional studies are needed to delineate the relative tip-over risks associated with CRT and flat panel display TVs.
Children <5 years of age have immature motor skills and judgment, and they are at higher risk for TV tip-over injury and suffer worse outcomes than older children. A 2006 study found that 85% of adults accompanying young children receiving emergency treatment of a TV tip-over injury were unaware that a child could be injured by a falling TV.17 Increased efforts to educate parents and child caregivers about the importance and prevention of injuries associated with TV tip-overs are clearly needed.35 Educational materials should be included with each new TV sale. Parents should appropriately place and anchor all TVs and should not place TV remote controls, toys, or other attractive items on top of a TV because this may encourage young children to climb and cause a TV tip-over.
In 2009, the voluntary safety standard for chests, door chests, and dressers was revised to require an antitip device or anchor be provided with the furniture at the point of sale.9 TVs are not covered by this voluntary standard, and even though they are implicated in approximately half of furniture-related tip-over injuries, no similar requirement applies to them.36 Extending this type of requirement to TVs as part of the Underwriters Laboratories standard that addresses TV stability would be an important step in decreasing the number of injuries resulting from falling TVs.8 Unanchored TVs in the home are unsafe. Cars are not sold without safety belts, and similarly, TVs should not be sold without the necessary safety anchors. Initiatives to distribute TV anchoring devices, especially to households with young children, should also be undertaken.
TVs currently must meet the stability performance tests outlined in the UL 60065 safety standard for audio, video, and similar electronic equipment, which was most recently revised in late 2012.8 These stability tests include a tilt test, vertical force test, and horizontal force test, with test conditions varying according to TV parameters, such as weight, height, and screen size. Further strengthening of these stability performance requirements, and redesign of TVs to meet these more stringent requirements, is another important strategy for prevention of injuries from falling TVs.
This study had a number of limitations. The NEISS likely underestimates the true number of TV-related injuries because it only captures injuries treated in hospital EDs and not those treated in other medical settings or those for which medical treatment is not sought. Fatalities are also not captured well by the NEISS. Another limitation is the inconsistent amount of detail contained in NEISS narratives, which is limited by the information documented in ED medical records by health care professionals and also by the details extracted by NEISS coders. Bias may exist in the descriptive data reported; for example, parents may be more likely to report, and ED personnel and NEISS coders may be more likely to document, furniture that is unsuitable to support TVs and neglect to report appropriate furniture. An additional limitation was the lack of sufficient information in NEISS narratives to determine whether the TVs were CRT or flat-screen designs. More complete and consistent documentation in NEISS narratives about the type and size of TV involved in the injury would help inform and evaluate future prevention efforts. Another limitation of this study was the lack of data quantifying exposure of children to TVs; however, the use of US Census data to calculate population-based injury rates is an acceptable method.
Conclusions
The rate of pediatric injuries caused by falling TVs is increasing, which underscores the need for increased prevention efforts. Prevention strategies include public education, provision of TV anchoring devices at the point of sale of TVs, TV anchoring device distribution programs, strengthening of standards for TV stability, and redesign of TVs to improve stability.
