Pediatric Dance-Related Injuries Treated in Emergency Departments in the United States, 2000-2020.

OBJECTIVE: This study investigated the characteristics and trends of children aged 3 to 19 years treated in US emergency departments for dance-related injuries. METHODS: Retrospective analysis of data from the National Electronic Injury Surveillance System from 2000 through 2020 was conducted. RESULTS: An estimated 489,119 children received emergency treatment for a dance-related injury, averaging 23,291 children annually, and the rate of injury increased 68.1% during the 21-year study period. Girls accounted for 80.3% and children aged 15 to 19 years accounted for 46.5% of cases. Sprains/strains were the most frequent diagnosis (44.4%), and lower extremities were the most commonly injured body region (56.4%). Compared with other body regions, patients aged 3 to 10 years were more likely to sustain head/neck injuries (odds ratio, 3.94, 95% confidence interval, 3.42-4.52) than 11- to 19-year-olds. Falls and noncontact mechanisms of injury accounted for 35.6% and 32.1% of injuries, respectively. Unstructured dance activity was associated with 30.8% of dance-related injuries overall and 67.0% among children aged 3 to 5 years. Ballet/pointe dancers frequently sustained lower extremity sprains/strains (39.2%). Compared with other dance types, break dancing was more commonly associated with injuries to an upper extremity than other body regions (odds ratio, 4.76, 95% confidence interval, 3.66-6.19). CONCLUSIONS: The rate of pediatric dance-related injuries treated in US emergency departments is increasing. Unstructured dance activity was an important source of dance-related injury, especially among children aged 3 to 5 years. The injury diagnosis and body region injured varied by child age and type of dance. Additional targeted prevention efforts should be implemented that address the injury characteristics of dancer subgroups.

Antidepressant exposures associated with exploratory behavior among young children reported to United States poison control centers, 2000-2020.

PURPOSE: This study investigates characteristics and trends of antidepressant exposures among children <6 years old related to exploratory behavior reported to US poison control centers. METHODS: Using data from the National Poison Data System for 2000-2020, population-based annual exposure rates by sex, antidepressant category, serious medical outcome, and health care facility admission were analyzed and odds ratios to assess associations of exposure type and antidepressant category with medical outcome and admission were calculated. RESULTS: There were 215 909 first-ranked unintentional exploratory exposures involving antidepressants among children <6 years old during the study period, averaging 10 281 annually. Most cases were <3 years old (77.8%), involved a single substance (86.9%), and did not receive treatment at a health care facility (57.6%); however, 7.9% were admitted and 3.4% had serious medical outcomes, including 13 deaths. SSRIs were involved in 56.9% of all cases. Compared with SSRIs, bupropion (OR: 5.22, 95% CI: 4.68-5.82), TCAs (OR: 3.74, 95% CI: 3.44-4.07), SNRIs (OR: 2.39, 95% CI: 2.11-2.71), and lithium salts (OR: 2.00, 95% CI: 1.63-2.46) were more likely to be associated with a serious medical outcome. TCAs were the first-ranked substance in 7 of the 13 deaths. CONCLUSIONS: Although most unintentional antidepressant exposures related to pediatric exploratory behavior were inconsequential, an important minority of cases required admission to a HCF or had a serious medical outcome, including 13 deaths. Therefore, increased efforts to prevent these exposures among young children are needed, including public education and improved medication packaging.

Motor vehicle-related electric scooter injuries in the US: A descriptive analysis of NEISS data.

INTRODUCTION: The introduction of scooter-share programs across the United States has led to an increased incidence of electronic scooter (e-scooter) injuries presenting to emergency departments (EDs). As legislation begins to push scooters from the sidewalk to the street, injuries resulting from collisions between e-scooters and motor vehicles are an important, but poorly characterized consideration. This study leverages data from a national injury surveillance system to characterize e-scooter versus motor vehicle collisions resulting in ED presentation. METHODS: This study utilizes data from the National Electronic Injury Surveillance System (NEISS). NEISS was queried for e-scooter-related injuries from January 1st, 2015 through December 31st, 2019. Injuries were characterized as motor vehicle-related (MV-involved) or non-motor-vehicle-related (MV-uninvolved) based on a manual review by the study investigators. Weighted tabular analyses were used to characterize both types of e-scooter injuries across demographic, diagnostic, and event-related factors. RESULTS: Over the study period an estimated 60,554 (95% CI: 37,525-84,594) injuries were treated in US EDs. Approximately 19% of these injuries involved motor vehicles. Those sustaining MV-involved injuries were significantly younger (p = 0.01), with a higher proportion of males injured (p = 0.01). Additionally, when compared to MV-uninvolved injuries, a significantly higher proportion of those with MV-involved injuries were admitted to the hospital for treatment (8.8% vs. 14.6%, p < 0.01). MV-involved injuries occurred primarily in the street (96.3%), while MV-uninvolved injuries were split across streets (44.0%), at one's home (~20%), and on public property (~20%) (p < 0.01). CONCLUSIONS: Electric scooter injuries involving a motor vehicle differed from those that did not across several key categories. As e-scooters and motor vehicles start to share the road more frequently, greater consideration should be made regarding how these two modes of transportation interact with each other. The promotion of thoughtful e-scooter legislation and infrastructure changes could help promote safer travel.

Comparison of the effectiveness of female voice, male voice, and hybrid voice-tone smoke alarms for sleeping children.

BACKGROUND: To test whether children awaken from slow wave sleep and perform an escape procedure better in response to a smoke alarm that uses a male voice, female voice, combination of a low-frequency tone plus a female voice (hybrid alarm), or high-frequency tone. METHODS: Using a randomized, non-blinded, repeated-measures design, 188 children aged 5-12 years were exposed during stage 4 slow wave sleep to four smoke alarms. RESULTS: Among study subjects, 84.6%, 87.2%, 88.8%, and 56.4% awakened and 84.0%, 86.7%, 88.8%, and 55.3% successfully performed the escape procedure within 5 min of alarm onset in response to the male voice, female voice, hybrid, and high-frequency tone alarms, respectively, while the median time-to-escape was 12.0, 12.0, 13.0, and 96.5 s for these four alarms, respectively. All pairwise comparisons between the high-frequency tone alarm and each of the other three alarms were statistically significant for the proportions of subjects who awakened or escaped and for time-to-awaken and time-to-escape. There were no significant differences in these outcome measures between the latter three alarms. CONCLUSIONS: Use of the male or female voice or hybrid alarms in children's sleep areas may reduce residential fire-related injuries and deaths among children old enough to perform self-rescue. IMPACT: The male voice, female voice, and hybrid alarms were each significantly more effective than a high-frequency tone alarm in awakening children aged 5-12 years from slow wave sleep and prompting their performance of an escape procedure. There were no significant differences in the effectiveness of the male voice, female voice, and hybrid alarms when compared with each other. Use of these alarms in children's sleep areas may reduce residential fire-related injuries and deaths among children old enough to perform self-rescue.

Suicide-related over-the-counter analgesic exposures reported to United States poison control centers, 2000-2018.

PURPOSE: To investigate suicide-related over-the-counter (OTC) analgesic medication exposures among individuals ≥6 years old reported to United States (US) poison control centers. METHODS: Data from the National Poison Data System for the years 2000-2018 were retrospectively analyzed. RESULTS: From 2000 to 2018, US poison control centers recorded 549 807 suicide-related cases involving OTC analgesics, including 327 781 cases (59.6%) admitted to the hospital and 1745 deaths (0.3%). Most cases involved a single substance (67.5%) and occurred among females (72.7%) and individuals 6-19 years old (49.7%). Overall, the rate of exposures increased significantly by 33.5% from 2000 to 2018, primarily driven by the increasing exposure rate among 6- to 19-year-old females. From 2000 to 2018, exposure rates for acetaminophen and ibuprofen increased, while that for acetylsalicylic acid decreased. Additionally, the proportion of cases resulting in a serious medical outcome or healthcare facility admission increased for all types of OTC analgesics. Acetaminophen and acetylsalicylic acid accounted for 48.0% and 18.5% of cases, respectively, and 64.5% and 32.6% of deaths, respectively. Both acetaminophen and acetylsalicylic acid had greater odds of healthcare facility admission (ORs 2.56 and 2.63, respectively) and serious medical outcomes (ORs 2.54 and 4.90, respectively) compared with ibuprofen. CONCLUSIONS: The rate of suicide-related OTC analgesic cases is increasing. Acetaminophen and acetylsalicylic acid cases are associated with greater morbidity and mortality. Prevention efforts should include implementing unit-dose packaging requirements and restrictions on package sizes and purchase quantities for acetaminophen and acetylsalicylic acid products to reduce access to large quantities of these analgesics.

Nonfatal horse-related injuries treated in emergency departments in the United States, 1990-2017.

BACKGROUND: Horse-related injuries can cause severe morbidity and mortality. The objective of this study is to investigate the epidemiological features of horse-related injuries treated in emergency departments (EDs) in the United States. METHODS: A retrospective analysis of horse-related injuries from 1990 through 2017 was conducted utilizing the National Electronic Injury Surveillance System (NEISS). Cases were identified using the NEISS code 1239 (Horseback Riding: Activity, Apparel, or Equipment). Analyses performed included calculation of national injury estimates, relative risks (RRs) with 95% confidence intervals (CIs), and linear regression. RESULTS: From 1990 through 2017, an estimated 1,836,536 (95% CI: 1,494,788-2,178,284) individuals presented to United States EDs with horse-related injuries. The annual injury rate decreased by 30.8% from 1990 to 1996, increased by 33.0% from 1996 to 2000, and then decreased by 46.0% from 2000 to 2017. Among older adults >60 years of age, the annual injury rate increased by 139.6% during the study period. The number of concussion and closed head injury diagnoses increased by 337.2% from 1990 to 2009. The most common mounted mechanism of injury was a fall or being thrown (73.9%), while the most common unmounted mechanism was being kicked (42.1%). Mounted injuries were more likely to lead to hospitalization than unmounted injuries (RR, 2.10, 95% CI: 1.59-2.77). CONCLUSIONS: Despite the recent decline in horse-related injuries, these injuries are still common. Clinicians should be aware of the spectrum of ED presentations of horse-related injuries. Prevention efforts focused on older adults and concussions and closed head injuries warrant special attention.

Nonfatal Pediatric Injuries Associated With Consumer Products and Sports and Recreational Activities in the United States.

OBJECTIVE: The aim of this study was to investigate the epidemiology of nonfatal consumer product- and sports and recreational activity-related injuries among US children. METHODS: National Electronic Injury Surveillance System data regarding children younger than 18 years who were treated in US emergency departments (EDs) for nonfatal consumer product- or sports and recreational activity-related injuries were analyzed. RESULTS: From 1990 through 2012, an estimated 121,489,024 (95% confidence interval, 104,226,323-138,751,726) children younger than 18 years were treated in US EDs for nonfatal injuries meeting study criteria, yielding an average of 5,282,131 children annually, or 74.12 injuries per 1000 children. During 1990 to 2005, the overall annual injury rate decreased by 14.0% (P < 0.001), followed by an increase of 7.3% (P = 0.157) during 2005 to 2012. The concussion/closed head injury rate increased by 199.3% (P < 0.001) from 1996 to 2012. Injury rates were highest among children 0 to 4 years old and lowest among children 5 to 9 years old. Sports and recreational activities accounted for 46.5% of all injuries. Falls (40.2%) and "struck-by" (22.6%) were the leading mechanisms of injury, and 62.3% of all injuries were among boys. Injuries often occurred to the head/neck (37.8%) or upper extremities (31.9%), were frequently diagnosed as lacerations (29.0%) or soft tissue injuries (21.0%), and 2.7% were admitted to the hospital. CONCLUSIONS: On average, a child was treated in a US ED for a nonfatal consumer product- or sports and recreational activity-related injury every 6 seconds. Although injury rates decreased early in the study period, there was a nonsignificant increasing trend from 2005 to 2012. Multilevel injury prevention efforts are recommended.

Putting Policy Into Practice: School-Level Compliance With and Implementation of State Concussion Laws.

CONTEXT: Each year, approximately 2 million US children 18 years or younger sustain a concussion, a type of mild traumatic brain injury (TBI). Concussions can have detrimental effects on physical, cognitive, emotional, or sleep health. POLICY: Between 2009 and 2014, all 50 US states and Washington, District of Columbia, enacted state concussion laws aimed to increase awareness about concussion and reduce the prevalence and severity of this injury. Most state laws include the following core tenets: (1) immediate removal from play after an actual or suspected concussion; (2) medical clearance before an athlete can return to play (RTP); and (3) concussion education for athletes, parents, and coaches. IMPLEMENTATION: State concussion laws allow for substantial interpretation at the school level, resulting in considerable variation in the content of school written concussion policies and the level of implementation of state law requirements at the school level. EVALUATION: We assessed the degree of high school written concussion policy compliance with the respective state law and examined the relationship between concussion policy compliance and school-level implementation of concussion laws. Seventy-one school officials completed a semistructured telephone interview and submitted their school's written concussion policy. Of the 71 policies analyzed, most complied with the removal-from-play, RTP, and concussion education tenets (90.1%, 97.2%, and 76.1%, respectively). The majority of participants reported that their school implemented the removal-from-play (91.5%), RTP (93.0%), and concussion education (80.6%) tenets well or very well. No significant relationships were found between researcher-rated school policy compliance and school-reported implementation of state law requirements at the school level. DISCUSSION: Our findings suggest that most participating schools complied with their state concussion law and implemented law requirements well or very well. Future studies should identify facilitators and barriers to the implementation of state concussion laws at the school level.

Effectiveness of a Voice Smoke Alarm Using the Child's Name for Sleeping Children: A Randomized Trial.

OBJECTIVES: To test maternal voice alarm effectiveness under residential conditions and determine whether personalizing the maternal voice alarm message with the child's first name improves effectiveness. STUDY DESIGN: Using a randomized, nonblinded, repeated measures design, we compared 3 maternal voice smoke alarms with respect to their ability to awaken 176 children 5-12 years old from stage 4 slow-wave sleep and prompt their performance of an escape procedure. A conventional residential high-frequency tone smoke alarm was used as a comparative reference. Children's sleep stage was monitored in a residence-like research setting. RESULTS: Maternal voice alarms awakened 86%-91% of children and prompted 84%-86% to escape compared with 53% awakened and 51% escaped for the tone alarm. A sleeping child was 2.9-3.4 times more likely to be awakened by each of the 3 voice alarms than the tone alarm. The median time to awaken was 156 seconds for the tone alarm and 2 seconds for each voice alarm. The proportions of children who awakened and escaped differed significantly between the tone alarm and each voice alarm, but no significant differences were found between each pair of the voice alarms, regardless of whether the child's first name was included in the alarm message. CONCLUSIONS: The maternal voice alarms significantly outperformed the tone alarm under residential conditions. Personalizing the alarm message with the child's first name did not increase alarm effectiveness. These findings have important implications for development of an effective and practical smoke alarm for children. TRIAL REGISTRATION: ClinicalTrials.gov: NCT01169155.

Antidepressant and antipsychotic medication errors reported to United States poison control centers.

PURPOSE: To investigate unintentional therapeutic medication errors associated with antidepressant and antipsychotic medications in the United States and expand current knowledge on the types of errors commonly associated with these medications. METHODS: A retrospective analysis of non-health care facility unintentional therapeutic errors associated with antidepressant and antipsychotic medications was conducted using data from the National Poison Data System. RESULTS: From 2000 to 2012, poison control centers received 207 670 calls reporting unintentional therapeutic errors associated with antidepressant or antipsychotic medications that occurred outside of a health care facility, averaging 15 975 errors annually. The rate of antidepressant-related errors increased by 50.6% from 2000 to 2004, decreased by 6.5% from 2004 to 2006, and then increased 13.0% from 2006 to 2012. The rate of errors related to antipsychotic medications increased by 99.7% from 2000 to 2004 and then increased by 8.8% from 2004 to 2012. Overall, 70.1% of reported errors occurred among adults, and 59.3% were among females. The medications most frequently associated with errors were selective serotonin reuptake inhibitors (30.3%), atypical antipsychotics (24.1%), and other types of antidepressants (21.5%). Most medication errors took place when an individual inadvertently took or was given a medication twice (41.0%), inadvertently took someone else's medication (15.6%), or took the wrong medication (15.6%). CONCLUSIONS: This study provides a comprehensive overview of non-health care facility unintentional therapeutic errors associated with antidepressant and antipsychotic medications. The frequency and rate of these errors increased significantly from 2000 to 2012. Given that use of these medications is increasing in the US, this study provides important information about the epidemiology of the associated medication errors.

Analgesic-Related Medication Errors Reported to US Poison Control Centers.

Objective: This study investigates the characteristics and trends of medication errors involving analgesic medications. Design and Methods: A retrospective analysis was conducted of analgesic-related medication errors reported to the National Poison Data System (NPDS) from 2000 through 2012. Results: From 2000 through 2012, the NPDS received 533,763 reports of analgesic-related medication errors, averaging 41,059 medication errors annually. Overall, the rate of analgesic-related medication errors reported to the NPDS increased significantly by 82.6% from 2000 to 2009, followed by a 5.7% nonsignificant decrease from 2009 to 2012. Among the analgesic categories, rates of both acetaminophen-related and opioid-related medication errors reported to the NPDS increased during 2000-2009, but the opioid error rate leveled off during 2009-2012, while the acetaminophen error rate decreased by 17.9%. Analgesic-related medication errors involved nonsteroidal anti-inflammatory drugs (37.0%), acetaminophen (35.5%), and opioids (23.2%). Children five years or younger accounted for 38.8% of analgesics-related medication errors. Most (90.2%) analgesic-related medication errors were managed on-site, rather than at a health care facility; 1.6% were admitted to a hospital, and 1.5% experienced serious medical outcomes, including 145 deaths. The most common type of medication error was inadvertently taking/given the medication twice (26.6%). Conclusion: Analgesic-related medication errors are common, and although most do not result in clinical consequences, they can have serious adverse outcomes. Initiatives associated with the decrease in acetaminophen-related medication errors among young children merit additional research and potential replication as a model combining government policy and multisectoral collaboration.

Stair-related injuries treated in United States emergency departments.

OBJECTIVE: To investigate the characteristics of stair-related injuries among individuals of all ages and estimate national injury frequencies and rates using a representative sample of patients treated in United States emergency departments. METHODS: Data from the National Electronic Injury Surveillance System were analyzed for patients treated for stair-related injuries in United States emergency departments from 1990 through 2012. RESULTS: An estimated 24,760,843 patients were treated in emergency departments for a stair-related injury during the 23-year study period, averaging 1,076,558 patients annually, or 37.8 injuries per 10,000 United States residents. The annual rate of stair-related injuries decreased by 12.6% (p<0.001) during 1990-1996, followed by an increase of 24.0% (p<0.001) during 1996-2012. Although the highest injury rates occurred among younger children and older adults, the majority (67.2%) of emergency department visits for stair-related injuries was by individuals 11-60years old. Most patients were female (62.4%), who also had a higher injury rate (46.5 vs. 29.1 per 10,000) than males. Sprains and strains (32.3%), soft tissue injuries (23.8%), and fractures (19.3%) were the most common types of injury. The body regions most frequently injured were the lower extremities (42.1%) and head/neck (21.6%). Patients ≤10years old experienced more head/neck injuries. Older adult patients more frequently sustained fractures than younger age groups. CONCLUSIONS: Stairs are a common source of injury among individuals of all ages and the frequency and rate of stair-related injuries are increasing. This underscores the need for increased prevention efforts, particularly those related to stair design and construction.

Length of Recovery From Sports-Related Concussions in Pediatric Patients Treated at Concussion Clinics.

OBJECTIVES: We quantified the length of recovery time by week in a cohort of pediatric sports-related concussion patients treated at concussion clinics, and examined patient and injury characteristics associated with prolonged recovery. DESIGN: A retrospective, cohort design. SETTING: Seven concussion clinics at a Midwest children's hospital. PATIENTS: Patients aged 10 to 17 years with a diagnosed sports-related concussion presenting to the clinic within 30 days of injury. MAIN OUTCOME MEASURES: Length of recovery by week. METHODS: Unadjusted and adjusted multinomial logistic regression analyses were used to model the effect of patient and injury characteristics on length of recovery by week. RESULTS: Median length of recovery was 17 days. Only 16.3% (299/1840) of patients recovered within one week, whereas 26.4% took longer than four weeks to recover. By 2 months postinjury, 6.7% of patients were still experiencing symptoms. Higher symptom scores at injury and initial visit were significantly associated with prolonged symptoms by week. Patients who presented to the clinic more than 2 weeks postinjury or who had 2 or more previous concussions showed increased risk for prolonged recovery. Females were at greater risk for prolonged recovery than males (odds ratio = 2.08, 95% confidence interval = 1.49-2.89). Age was not significantly associated with recovery length. CONCLUSIONS: High symptom scores at injury and initial visit, time to initial clinical presentation, presence of 2 or more previous concussions, and female sex are associated with prolonged concussion recovery. Further research should aim to establish objective measures of recovery, accounting for treatment received during the recovery. CLINICAL RELEVANCE: The median length of recovery is 17 days among pediatric sports-related concussion patients treated at concussion clinics. Only 16.3% of patients recovered within one week, whereas 26.4% took longer than 4 weeks to recover.

Pediatric Cotton-Tip Applicator-Related Ear Injury Treated in United States Emergency Departments, 1990-2010.

OBJECTIVE: To evaluate the characteristics of children with cotton-tip applicator (CTA)-related ear injuries. STUDY DESIGN: Data on CTA-related ear injuries among children presenting to US emergency departments (EDs) from 1990 through 2010 were obtained from the National Electronic Injury Surveillance System. RESULTS: Between 1990 and 2010, an estimated 263 338 children aged <18 years were treated for CTA-related ear injuries in US hospital EDs. There was a nonsignificant increase in the annual number of injuries from 1990 through 2001 (78.2%) and a significant decrease from 2001 through 2010 (26.0%). Younger children sustained the highest rate of injury (32.2 per 100 000 for age 0-3 years). Ear cleaning was the most frequently documented circumstance at the time of injury (73.2%), and patients themselves were most commonly handling the CTA (76.9%). Foreign body sensation (39.2%) and bleeding (34.8%) were commonly documented reasons for visiting the ED. The presence of a foreign body (29.7%) and tympanic membrane perforation (25.3%) were common diagnoses. CONCLUSION: Most CTA-related injuries occurred with children themselves handling CTAs while cleaning their ears. Foreign body and tympanic membrane perforation were the most common associated diagnoses. Despite warnings against the use of CTAs in the ear canal and use of CTAs by children, these injuries continued to occur. Additional injury prevention strategies through further parent/caregiver and child education are warranted.

Non-Health Care Facility Cardiovascular Medication Errors in the United States.

BACKGROUND: Prior studies have not examined national trends and characteristics of unintentional non-health care facility (HCF) medication errors associated with cardiovascular drugs. OBJECTIVE: To investigate non-HCF medication errors associated with cardiovascular drugs reported to poison control centers in the United States. METHODS: A retrospective analysis of non-HCF medication errors associated with cardiovascular drugs from 2000 to 2012 was conducted using the National Poison Data System database. RESULTS: There were 278 444 medication errors associated with cardiovascular drugs reported to US poison control centers during the study period, averaging 21 419 exposures annually. The overall rate of cardiovascular medication errors per 100 000 population increased 104.6% from 2000 to 2012 ( P < 0.001) and the highest rates were among older adults. Most cases (83.6%) did not require treatment at a HCF. Serious medical outcomes were reported in 4.0% of exposures. The cardiovascular drugs most commonly implicated in medication errors were ß-blockers (28.2%), calcium antagonists (17.7%), and angiotensin-converting enzyme inhibitors (15.9%). Most of the 114 deaths were associated with cardiac glycosides (47.4%) or calcium antagonists (29.8%). Most medication errors involved taking or being given a medication twice (52.6%). CONCLUSIONS: This study describes characteristics and trends of non-HCF cardiovascular medication errors over a 13-year period in the United States. The number and rate of cardiovascular medication errors increased steadily from 2000 to 2012, with the highest error rates among older adults. Further research is needed to identify prevention strategies for these errors, with a particular focus on the older adult population.

Golf-related injuries treated in United States emergency departments.

OBJECTIVE: This study investigates unintentional non-fatal golf-related injuries in the US using a nationally representative database. METHODS: This study analyzed golf-related injuries treated in US hospital emergency departments from 1990 through 2011 using the National Electronic Injury Surveillance System database. Injury rates were calculated using golf participation data. RESULTS: During 1990 through 2011, an estimated 663,471 (95% CI: 496,370-830,573) individuals ≥7years old were treated in US emergency departments for golf-related injuries, averaging 30,158 annually or 12.3 individuals per 10,000 golf participants. Patients 18-54years old accounted for 42.2% of injuries, but injury rates per 10,000 golf participants were highest among individuals 7-17years old (22.1) and ≥55years old (21.8) compared with 18-54years old (7.6). Patients ≥55years old had a hospital admission rate that was 5.01 (95% CI: 4.12-6.09) times higher than that of younger patients. Injured by a golf club (23.4%) or struck by a golf ball (16.0%) were the most common specified mechanisms of injury. The head/neck was the most frequently injured body region (36.2%), and sprain/strain (30.6%) was the most common type of injury. Most patients were treated and released (93.7%) and 5.9% required hospitalization. CONCLUSIONS: Although golf is a source of injury among all age groups, the frequency and rate of injury were higher at the two ends of the age spectrum. Given the higher injury and hospital admission rates of patients ≥55years, this age group merits the special attention of additional research and injury prevention efforts.

Children treated for lawn mower-related injuries in US emergency departments, 1990-2014.

OBJECTIVE: Investigate the epidemiology of lawn mower-related injuries to children in the US. METHODS: A retrospective analysis was conducted of children younger than 18years of age treated in US emergency departments for a lawn mower-related injury from 1990 through 2014 using data from the National Electronic Injury Surveillance System. RESULTS: An estimated 212,258 children <18years of age received emergency treatment for lawn mower-related injuries from 1990 through 2014, equaling an average annual rate of 11.9 injuries per 100,000 US children. The annual injury rate decreased by 59.9% during the 25-year study period. The leading diagnosis was a laceration (38.5%) and the most common body region injured was the hand/finger (30.7%). Struck by (21.2%), cut by (19.9%), and contact with a hot surface (14.1%) were the leading mechanisms of injury. Patients <5years old were more likely (RR 7.01; 95% CI: 5.69-8.64) to be injured from contact with a hot surface than older patients. A projectile was associated with 49.8% of all injuries among patients injured as bystanders. Patients injured as passengers or bystanders were more likely (RR 3.77; 95% CI: 2.74-5.19) to be admitted to the hospital than lawnmower operators. CONCLUSIONS: Lawn mower-related injuries continue to be a cause of serious morbidity among children. Although the annual injury rate decreased significantly over the study period, the number of injuries is still substantial, indicating the need for additional prevention efforts. In addition to educational approaches, opportunities exist for improvements in mower design and lawn mower safety standards.

Grill-Related Injuries in Children Treated in US Emergency Departments, 1990-2009.

OBJECTIVE: The aim of the study was to describe grill-related injuries in pediatric patients seeking emergency treatment. METHODS: Data from the National Electronic Injury Surveillance System from 1990 through 2009 were investigated. Sample weights were used to calculate national estimates. United States Census Bureau data were used to calculate injury rates per 100,000 individuals. Linear regression and computation of relative risks (RRs) with 95% confidence intervals (CIs) were performed. RESULTS: An estimated 308,560 children were treated in US emergency departments for grill-related injuries during the study period, with an average of 15,428 cases per year. The rate of injuries increased by 32.3% during the study period. Males (62.8%) and children aged 11 to 18 years (55.8%) sustained the largest number of injuries. Children younger than 5 years were more likely to injure the head and neck (RR, 1.26 [95% CI, 1.21-1.33]), be injured by impact with a grill (RR, 1.97 [95% CI, 1.88-2.07]), and sustain burns (RR, 1.39 [95% CI, 1.35-1.45]) when compared with other age groups. Children aged 11 to 18 years were more likely to experience a fracture or dislocation (RR, 2.07 [95% CI, 1.58-2.72]) and more likely to sustain a grill-related injury while the grill was not in use (RR, 7.95 [95% CI, 6.25-10.12]). CONCLUSIONS: The rate of grill-related injuries among children is increasing, which underscores the need for increased prevention efforts. Prevention strategies should address measures such as lighting a grill and grill location in addition to burn prevention.

Zipline-related injuries treated in US EDs, 1997-2012.

PURPOSE: To investigate the epidemiology of zipline-related injuries in the United States. BASIC PROCEDURES: The National Electronic Injury Surveillance System database was used to examine non-fatal zipline-related injuries treated in US emergency departments (EDs) from 1997 through 2012. Sample weights were applied to calculate national estimates. MAIN FINDINGS: From 1997 through 2012, an estimated 16850 (95% CI, 13188-20512) zipline-related injuries were treated in US EDs. The annual injury rate per 1 million population increased by 52.3% from 7.64 (95% CI, 4.86-10.42) injuries in 2009 (the first year with a stable annual estimate) to 11.64 (95% CI, 7.83-15.45) injuries in 2012. Patients aged 0-9 years accounted for 45.0% of injuries, females made up 53.1% of injuries, and 11.7% of patients required hospitalization. Fractures accounted for the largest proportion of injuries (46.7%), and the upper extremities were the most commonly injured body region (44.1%). Falls were the most common mechanism of injury, accounting for 77.3% of injuries. Among cases where the location of the injury event was known, 30.8% of injuries occurred in a residential setting and 69.2% occurred in a public place. PRINCIPAL CONCLUSIONS: This study is the first to characterize the epidemiology of zipline-related injuries using a nationally representative database. The rapid increase in zipline-related injuries in recent years suggests the need for additional safety guidelines and regulations. Commercial ziplines and publicly accessible non-commercial ziplines should be subject to uniform safety standards in all states and jurisdictions across the US, and homemade ziplines should not be used.
