RESUMO
BACKGROUND: Powered, two-wheeled transportation devices like electric bicycles (E-bikes) and scooters are increasingly popular, but little is known about their relative injury risk compared to pedal operated bicycles. METHODS: Descriptive and comparative analysis of injury patterns and trends associated with E-bikes, powered scooters and pedal bicycles from 2000 to 2017 using the US National Electronic Injury Surveillance System. RESULTS: While persons injured using E-bikes were more likely to suffer internal injuries (17.1%; 95% CI 5.6 to 28.6) and require hospital admission (OR=2.8, 95% CI 1.3 to 6.1), powered scooter injuries were nearly three times more likely to result in a diagnosis of concussion (3% of scooter injuries vs 0.5% of E-bike injuries). E-bike-related injuries were also more than three times more likely to involve a collision with a pedestrian than either pedal bicycles (OR=3.3, 95% CI 0.5 to 23.6) or powered scooters (OR=3.3, 95% CI 0.3 to 32.9), but there was no evidence that powered scooters were more likely than bicycles to be involved in a collision with a pedestrian (OR=1.0, 95% CI 0.3 to 3.1). While population-based rates of pedal bicycle-related injuries have been decreasing, particularly among children, reported E-bike injuries have been increasing dramatically particularly among older persons. CONCLUSIONS: E-bike and powered scooter use and injury patterns differ from more traditional pedal operated bicycles. Efforts to address injury prevention and control are warranted, and further studies examining demographics and hospital resource utilisation are necessary.

BACKGROUND: Traumatic injury is the leading cause of paediatric morbidity and mortality in the USA. We present updated national data on emergency department (ED) discharges for traumatic injury for a recent 7-year period. METHODS: We conducted a descriptive epidemiological analysis of the Nationwide Emergency Department Sample Survey, the largest and most comprehensive database in the USA, for 2006-2012. Among children and adolescents, we tracked changes in injury mechanism and severity, cost of care, injury intent and the role of trauma centres. RESULTS: There was an 8.3% (95% CI 7.7 to 8.9) decrease in the annual number of ED visits for traumatic injury in children and adolescents over the study period, from 8 557 904 (SE=5861) in 2006 to 7 846 912 (SE=5191) in 2012. The case-fatality rate was 0.04% for all injuries and 3.2% for severely injured children. Children and adolescents with high-mortality injury mechanisms were more than three times more likely to be treated at a level 1 trauma centre (OR=3.5, 95% CI 3.3 to 3.7), but were more no more likely to die (OR=0.96, 95% CI 0.93 to 1.00). Traumatic brain injury diagnoses increased 22.2% (95% CI 20.6 to 23.9) during the study period. Intentional assault accounted for 3% (SE=0.1) of all child and adolescent ED injury discharges and 7.2% (SE=0.3) of discharges among 15-19 year-olds. There was an 11.3% (95% CI 10.0 to 12.6) decline in motor vehicle injuries from 2009 to 2012. The total cost of care was $23 billion (SE=0.01), a 78% increase from 2006 to 2012. CONCLUSIONS: This analysis presents a recent portrait of paediatric trauma across the USA. These analyses indicate the important role and value of trauma centre care for injured children and adolescents, and that the most common causes and mechanisms of injury are preventable.

BACKGROUND: Early thoracotomy (ET) is a procedure performed on patients in extremis. Identifying factors associated with ET survival may allow for optimization of guidelines and improved patient selection. OBJECTIVES: The objective of this study was to assess whether ETs performed at Level I trauma centers (TC) are associated with improved survival. METHODS: This was a retrospective study utilizing the National Trauma Databank 2014-2015. We included all thoracotomies performed within 1 h of hospital arrival. Patients were stratified according to TC designation level. Patient demographics, outcomes, and center characteristics were compared. We conducted multivariable regression with survival as the outcome. RESULTS: There were 3183 ETs included in this study; 2131 (66.9%) were performed at Level I TCs. Patients treated at Level I and non-Level I TCs had similar median injury severity scores, as well as signs of life and systolic blood pressures on admission. Patients treated at Level I TCs had significantly higher survival rates (21.6% vs. 16.3%, p < 0.001), with 40% greater odds of survival after controlling for injury-specific factors and emergency medical services transportation time (adjusted odds ratio 1.40, 95% confidence interval 1.04-1.89, p = 0.03). Penetrating injuries had 23.1% survival after ET vs. 12.9% for blunt injuries (adjusted odds ratio 1.86, 95% confidence interval 1.37-2.53, p < 0.001). CONCLUSIONS: ETs performed at Level I TCs were associated with 40% greater odds of survival compared with ETs at non-Level I TCs. This demonstrates that factors extrinsic to the patient may play a role in survival of severely injured patients.

BACKGROUND: Between 1990 and 2003, there were 668 subway-related fatalities in New York City. However, subway-related trauma remains an understudied area of injury-related morbidity and mortality. OBJECTIVE: The objective of this study was to characterize the injuries and events leading up to the injuries of all patients admitted after subway-related trauma. METHODS: We conducted a retrospective case series of subway-related trauma at a Level I trauma center from 2001 to 2016. Descriptive epidemiology of patient demographics, incident details, injuries, and outcomes were analyzed. RESULTS: Over 15 years, 254 patients were admitted for subway-related trauma. The mean (standard error of the mean) age was 41 (1.0) years, 80% were male (95% confidence interval [CI] 74-84%) and median Injury Severity Score was 14 (interquartile range [IQR] 5-24). The overall case-fatality rate was 10% (95% CI 7-15%). The most common injuries were long-bone fractures, intracranial hemorrhage, and traumatic amputations. Median length of stay was 6 days (IQR 1-18 days). Thirty-seven percent of patients required surgical intervention. At the time of injury, 55% of patients (95% CI 49-61%) had a positive urine drug or alcohol screen, 16% (95% CI 12-21%) were attempting suicide, and 39% (95% CI 33-45%) had a history of psychiatric illness. CONCLUSIONS: Subway-related trauma is associated with a high case-fatality rate. Alcohol or drug intoxication and psychiatric illness can increase the risk of this type of injury.

BACKGROUND: Educational and computerized interventions have been shown to reduce red blood cell (RBC) transfusion rates, yet controversy remains surrounding the optimal strategy needed to achieve sustained reductions in liberal transfusions. STUDY DESIGN AND METHODS: The purpose of this study was to assess the impact of clinician decision support (CDS) along with targeted education on liberal RBC utilization to four high-utilizing service lines compared with no education to control service lines across an academic medical center. Clinical data along with associated hemoglobin levels at the time of all transfusion orders between April 2014 and December 2015 were obtained via retrospective chart review. The primary outcome was the change in the rate of liberal RBC transfusion orders (defined as any RBC transfusion when the hemoglobin level is >7.0 g/dL). Secondary outcomes included the annual projected reduction in the number of transfusions and the associated decrease in cost due to these changes as well as length of stay (LOS) and death index. These measures were compared between the 12 months prior to the initiative and the 9-month postintervention period. RESULTS: Liberal RBC utilization decreased from 13.4 to 10.0 units per 100 patient discharges (p = 0.002) across the institution, resulting in a projected 12-month savings of $720,360. The mean LOS and the death index did not differ significantly in the postintervention period. CONCLUSION: Targeted education combined with the incorporation of CDS at the time of order entry resulted in significant reductions in the incidence of liberal RBC utilization without adversely impacting inpatient care, whereas control service lines exposed only to CDS had no change in transfusion habits.

INTRODUCTION: Falls from heights are an important cause of unintentional fatal injury. We investigated the relationship between the characteristics of fatal falls and resulting injury patterns. MATERIALS AND METHODS: We reviewed prospectively collected data from the Office of Chief Medical Examiner in New York City between 2000 and 2010. Data included fall height, work or non-work related, use of safety equipment, intentionality, specific organ injuries, and death on impact. The primary outcome was organ injury based on fall height. RESULTS: Higher falls were associated with hemorrhage as well as rib and various organ injuries. Organ injury pattern did not differ based on work status. The presence of equipment misuse or malfunction was associated with more deaths upon impact. Victims of falls from 200 ft or higher were 11.59 times more likely to die on impact than from lower than 25 ft. CONCLUSIONS: Fall height and work-related falls were significantly associated with death on impact. This is a public health issue, as 13% of falls were work related and 4% of falls were due to improper use of safety equipment. Some work-related falls are potentially preventable with proper safety equipment use. Understanding patterns of injury may play a role in prevention and management of survivors in the acute period.

OBJECTIVES: We determined the demographic characteristics, behaviors, injuries, and outcomes of commercial bicyclists who were injured while navigating New York City's (NYC's) central business district. METHODS: Our study involved a secondary analysis of prospectively collected data from a level 1 regional trauma center in 2008 to 2014 of bicyclists struck by motor vehicles. We performed univariable and multivariable logistic regression analyses. RESULTS: Of 819 injured bicyclists, 284 (34.7%) were working. Commercial bicyclists included 24.4% to 45.1% of injured bicyclists annually. Injured commercial bicyclists were more likely Latino (56.7%; 95% confidence interval [CI] = 50.7, 62.8 vs 22.7%; 95% CI = 19.2, 26.5). Commercial bicyclists were less likely to be distracted by electronic devices (5.0%; 95% CI = 2.7, 8.2 vs 12.7%; 95% CI = 9.9, 15.9) or to have consumed alcohol (0.7%; 95% CI = 0.9, 2.5 vs 9.5%; 95% CI = 7.2, 12.3). Commercial and noncommercial bicyclists did not differ in helmet use (38.4%; 95% CI = 32.7, 44.4 vs 30.8%; 95% CI = 26.9, 34.9). Injury severity scores were less severe in commercial bicyclists (odds ratio = 0.412; 95% CI = 0.235, 0.723). CONCLUSIONS: Commercial bicyclists represent a unique cohort of vulnerable roadway users. In NYC, minorities, especially Latinos, should be targeted for safety education programs.

OBJECTIVE: Road safety constitutes a crisis with important health and economic impacts. In 2010, 11,000 pedestrians and 3500 bicyclists were injured by motor vehicles in New York City (NYC). Motor vehicle injuries represent the second leading cause of injury-related deaths in NYC children aged 5 to 14 years. To better target injury prevention strategies, we evaluated demographics, behaviors, environmental factors, injuries, and outcomes of pediatric pedestrians and bicyclists struck by motor vehicles in NYC. METHODS: Pediatric data were extracted from a prospectively collected database of pedestrians and bicyclists struck by motor vehicles and treated at a level I regional trauma center between December 2008 and June 2011. Patients, guardians, and first responders were interviewed and medical records were reviewed. Institutional review board approval was granted and verbal consent was obtained. RESULTS: Of the 1457 patients, 168 (12%) were younger than 18 years. Compared with injured adults, children were more likely to be in male sex (69% vs 53%), to have minor injuries (83% vs 73% for injury severity scores of <9), and to be discharged without admission (69% vs 67%). Midblock crossings were more common in children pedestrians than in adults (37% vs 19%), often despite supervision (48%). Electronic device use among teenagers aged 13 to 17 years was nearly 3 times that of adults (28% vs 11%). CONCLUSIONS: Risky behaviors are common among pediatric pedestrians and bicyclists injured by motor vehicles. Road safety education and prevention strategies must stress compliance with traffic laws, readdress the importance of supervision, and reinforce avoidance of common distractors including electronic devices.

BACKGROUND: Patient morbidity and mortality decrease when injured patients meeting CDC Field Triage Criteria (FTC) are transported by emergency medical services (EMS) directly to designated trauma centers (TCs). This study aimed to identify potential disparities in the transport of critically injured patients to TCs by EMS. STUDY DESIGN: We identified all patients in the National EMS Information System (NEMSIS) database in the National Association of EMS State Officials East region from January 1, 2018, to December 31, 2019, with a final prehospital acuity of critical or emergent by EMS. The cohort was stratified into patients transported to TCs or non-TCs. Analyses consisted of descriptive epidemiology, comparisons, and multivariable logistic regression analysis to measure the association of demographic features, vital signs, and CDC FTC designation by EMS with transport to a TC. RESULTS: A total of 670,264 patients were identified as sustaining an injury, of which 94,250 (14%) were critically injured. Of those 94,250 critically injured, 56.0% (52,747) were transported to TCs. Among all critically injured women (n = 41,522), 50.4% were transported to TCs compared with 60.4% of critically injured men (n = 52,728, p < 0.001). In a multivariable logistic regression model, critically injured women were 19% less likely to be taken to a TC compared with critically injured men (OR 0.81, 95% CI 0.71-0.93, p = 0.003). CONCLUSIONS: Critically injured female patients are less likely to be transported to TCs when compared with their male counterparts. Performance improvement processes that assess EMS compliance with field triage guidelines should explicitly evaluate for sex-based disparities. Further studies are warranted.

BACKGROUND: Alcohol and other drugs (AOD) increase the risk of traumatic injury occurring, but data suggest a protective benefit in preventing trauma-related mortality. The objective of this study is to describe the epidemiology of AOD-related traumatic injury in the US over a recent 7 year period and assess the interaction of traumatic injury and AOD on pre-admission fatality on both an additive scale using incidence contrasts and on a statistical multiplicative scale using survey-adjusted logistic regression. METHODS: Using the National Emergency Department Sample (NEDS), we describe the epidemiology of alcohol and substance-related emergency department traumatic injury over a recent period. AOD-related injury was assessed using survey-adjusted counts and means. Ratio estimates and differences were calculated using simulations based on survey-adjusted counts and standard errors. Differences in trends over time were evaluated by comparing the slopes of linear regression equations with year as the predictor variable. RESULTS: Alcohol and substance-related emergency department injury discharges increased 9.8 % during the study period. There was a statistically significant interaction between traumatic injury death and AOD on both an additive scale and multiplicative scale. (Odds Ratio for interaction term = 1.76, 95 % CI = 1.53, 2.03). CONCLUSIONS: AOD use does not provide a protective benefit in the setting of trauma, but rather is an important contributor to traumatic injury mortality.

BACKGROUND: While mass-casualty incidents (MCIs) may have competing absolute definitions, a universally ac-cepted criterion is one that strains locally available resources. In the fall of 2017, a MCI occurred in New York and Bellevue Hospital received multiple injured patients within minutes; lessons learned included the need for a formal-ized, efficient patient and injury tracking system. Our objective was to create an organized MCI clinical tracking form for civilian trauma centers. METHODS: After the MCI, the notes of the surgeon responsible for directing patient triage were analyzed. A suc-cinct, organized template was created that allows MCI directors to track demographics, injuries, interventions, and other important information for multiple patients in a real-time fashion. This tool was piloted during a subsequent MCI. RESULTS: In late 2018, the hospital received six patients following another MCI. They arrived within a 4-minute window, with 5 patients being critically injured. Two emergent surgeries and angioembolizations were performed. The tool was used by the MCI director to prioritize and expedite care. All physicians agreed that the tool assisted in orga-nizing diagnostic and therapeutic triage. CONCLUSIONS: During MCIs, a streamlined patient tracking template assists with information recall and communica-tion between providers and may allow for expedited care.

BACKGROUND: Elderly patients with Traumatic Brain Injury (TBI) are frequently transferred to designated Trauma Centers (TC). We hypothesized that TC transfer is associated with improved outcomes. METHODS: Retrospective study utilizing the National Trauma Databank. Demographics, injury and outcomes data were abstracted. Patients were dichotomized by transfer to a designated level I/II TC vs. not. Multivariate regression was used to derive the adjusted primary outcome, mortality, and secondary outcomes, complications and discharge disposition. RESULTS: 19,664 patients were included, with a mean age of 78.1 years. 70% were transferred to a level I/II TC. Transferred patients had a higher ISS (12 vs. 10, pâ¯<â¯0.001). Mortality was significantly lower in patients transferred to level I/II TCs (5.6% vs. 6.2%, Adjusted Odds Ratio (AOR) 0.84, pâ¯=â¯0.011), as was the likelihood of discharge to skilled nursing facilities (26.4% vs. 30.2%, AOR 0.80, pâ¯<â¯0.001). CONCLUSIONS: Elderly patients with mild TBI transferred to level I/II TCs have improved outcomes. Which patients with mild TBI require level I/II TC care should be examined prospectively.

This study evaluated the safety of early anti-factor Xa assay-guided enoxaparin dosing for chemoprophylaxis in patients with TBI. We hypothesized that assay-guided chemoprophylaxis would be comparable in the risk of intracranial hemorrhage (ICH) progression to fixed dosing. An observational analysis of adult patients with blunt traumatic brain injury (TBI) was performed at a Level I trauma center from August 2016 to September 2017. Patients in the assay-guided group were treated with an initial enoxaparin dose of 0.5 mg/kg, with peak anti-factor Xa activity measured four hours after the third dose. Prophylactic range was defined as 0.2 to 0.5 IU/mL with a dose adjustment of ± 10 mg based on the assay result. The assay-guided group was compared with historical fixed-dose controls and to a TBI cohort from the most recent Trauma Quality Improvement Project dataset. Of 179 patients included in the study, 85 were in the assay-guided group and 94 were in the fixed-dose group. Compared with the fixed-dose group, the assay-guided group had a lower Glasgow Coma Score and higher Injury Severity Score. The proportion of severe (Abbreviated Injury Score, head ≥3) TBI, ICH progression, and venous thromboembolism rates were similar between all groups. The assay-guided and fixed-dose groups had chemoprophylaxis initiated earlier than the Trauma Quality Improvement Project group. The assay-guided group had the highest percentage of low molecular weight heparin use. Early initiation of enoxaparin anti-factor Xa assay-guided venous thromboembolism chemoprophylaxis has a comparable risk of ICH progression to fixed dosing in patients with TBI. These findings should be validated prospectively in a multicenter study.

Managing mangled upper extremity injuries is a challenging problem because multiple tissue components including soft tissue, muscle, tendon, bone, nerves, and vessels are involved. The complexity of these injuries has hindered the development of accurate scoring systems and treatment algorithms. METHODS: Patients with mangled upper extremities presenting to a metropolitan level 1 trauma center in New York City over a 10-year period were identified. A mangled upper extremity was defined as any injury to ≥3 tissue components involving the extremity proximal to the digit. RESULTS: The injuries and outcomes of 76 patients were evaluated and used to create a Mangled Upper Extremity Score (MUES). One point was assigned for each of the following injury characteristics: patient age >40, fasciotomy needed, bony fixation required, bony defect present, revascularization required, crush injury mechanism, degloving or avulsion injury present, and a soft tissue defect >50 cm2. The MUES correlated with the number of complications (P value = 1.96 × 10-7) and length of hospital stay (P value = 3.95 × 10-7). Next, a Mangled Extremity Severity Score (MESS) equivalent was calculated for each patient. There was no correlation between the MESS and the number of complications (P value = 0.92) or length of hospital stay (P value = 0.35). CONCLUSIONS: Existing extremity scoring systems, including the MESS, are not reliable in predicting the success of limb salvage attempts or outcomes of mangled upper extremity injuries. The MUES developed in this study correlates significantly with important outcome measures including the number of hospital complications and length of hospital stay.
RESUMO
BACKGROUND: Firearm-related injuries cause significant morbidity and mortality in the United States (US), consuming resources and fueling political and public health discourse. Most analyses of firearm injuries are based on fatality statistics. Here, we describe the epidemiology of firearm injuries presenting to US emergency departments (EDs). METHODS: We performed a retrospective study of the Healthcare Cost and Utilization Program Nationwide Emergency Department Survey (NEDS) from 2009 to 2012. NEDS is the largest all-payer ED survey in the US containing approximately 30 million annual records. Results include survey-adjusted counts, proportions, means, and rates, and confidence intervals of age-stratified ED discharges for firearm injuries. RESULTS: There were 71,111 (se = 613) ED discharges for firearm injuries in 2009; the absolute number increased 3.9% (se = 1.2) to 75,559 (se = 610) in 2012. 18-to-44-year-olds accounted for the largest proportion of total injuries with 52,187 (se = 527) in 2009 and 56,644 (se = 528) in 2012-a 7.2% (se = 1.6) relative rate increase and an absolute increase of 3.3/100,000 (se = 0.7). Firearm injuries among children < 5-years-old increase 16%, and 19% among children 5-to-9-years-old. 136,112 (se = 761)-or 48.2%-of those injured were treated and discharged home without admission; 106,927 (se = 755) were admitted. Firearm deaths represented one-third of all trauma mortality. Three-quarters of those injured resided in neighborhoods with median incomes below $49,250. CONCLUSIONS: Firearm injuries increased from 2009 to 2012, driven by adults aged 18-to-44-years-old, and disproportionately impacting lower socioeconomic communities. Injuries also increased among young children. Firearm injuries remain a continued public health challenge, and a significant source of ED morbidity and mortality.
RESUMO
Sport Concussion Assessment Tool version 3 (SCAT-3) is one of the most widely researched concussion assessment tools in athletes. Here normative data for SCAT3 in nonathletes are presented. The SCAT3 was administered to 98 nonathlete healthy controls, as well as 118 participants with head-injury and 46 participants with other body trauma (OI) presenting to the ED. Reference values were derived and classifier functions were built to assess the accuracy of SCAT3. The control population had a mean of 2.30 (SD = 3.62) symptoms, 4.38 (SD = 8.73) symptom severity score (SSS), and 26.02 (SD = 2.52) standardized assessment of concussion score (SAC). Participants were more likely to be diagnosed with a concussion (from among healthy controls) if the SSS > 7; or SSS ≤ 7 and SAC ≤22 (sensitivity = 96%, specificity = 77%). Identification of head injury patients from among both, healthy controls and body trauma was possible using rule SSS > 7 and headache or pressure in head present, or SSS ≤ 7 and SAC ≤ 22 (sensitivity = 87%, specificity = 80%). In this current study, the SCAT-3 provided high sensitivity to discriminate acute symptoms of TBI in the ED setting. Individuals with a SSS > 7 and headache or pressure in head, or SSS ≤ 7 but with a SAC ≤ 22 within 48-hours of an injury should undergo further testing.

CONTEXT: The main pancreatic duct can form a fistulous communication with another epithelium in the setting of prolonged inflammation, operative manipulation, or direct trauma. We present a rare complication of a pancreaticoureteral fistula following a trauma nephrectomy. CASE REPORT: A 17-year-old male who sustained a gunshot wound to the back arrived to our Emergency Room hyopotensive, tachycardic, and with free intraperitoneal fluid on focused assessment sonography for trauma (FAST) exam. He was taken to the operating room for an exploratory laporatomy where a left nephrectomy was performed to control active bleeding from the left renal hilum. Significant bleeding was also encountered at the portal venous confluence. After packing and damage control laparotomy, the periportal/pancreatic bleeding was controlled during a second procedure 6 hours later. After one month in the Intensive Care Unit with an open abdomen, a computed tomography (CT) scan revealed a fluid collection in the splenic fossa which was drained by catheter. Persistent drainage revealed a high amylase concentration (greater than 50,000 U/L). A fistulogram revealed interruption of the main pancreatic duct, and a fluid collection by the tail of the pancreas that was in communication with the left ureter. The patient's urine amylase was also elevated. The patient was treated non-operatively given the healing open abdomen and controlled fistula. He had an otherwise uncomplicated recovery. CONCLUSIONS: This is the second report of a pancreaticoureteral fistula in the literature. Treatment of this communication should be similar to that of other pancreatic fistulae.

OBJECTIVE: Injury-related morbidity and mortality is an important emergency medicine and public health challenge in the United States. Here we describe the epidemiology of traumatic injury presenting to U.S. emergency departments (EDs), define changes in types and causes of injury among the elderly and the young, characterize the role of trauma centers and teaching hospitals in providing emergency trauma care, and estimate the overall economic burden of treating such injuries. METHODS: We conducted a secondary retrospective, repeated cross-sectional study of the Nationwide Emergency Department Data Sample (NEDS), the largest all-payer ED survey database in the United States. Main outcomes and measures were survey-adjusted counts, proportions, means, and rates with associated standard errors (SEs) and 95% confidence intervals. We plotted annual age-stratified ED discharge rates for traumatic injury and present tables of proportions of common injuries and external causes. We modeled the association of Level I or II trauma center care with injury fatality using a multivariable survey-adjusted logistic regression analysis that controlled for age, sex, injury severity, comorbid diagnoses, and teaching hospital status. RESULTS: There were 181,194,431 (SE = 4,234) traumatic injury discharges from U.S. EDs between 2006 and 2012. There was a mean year-to-year decrease of 143 (95% CI = -184.3 to -68.5) visits per 100,000 U.S. population during the study period. The all-age, all-cause case-fatality rate for traumatic injuries across U.S. EDs during the study period was 0.17% (SE = 0.001%). The case-fatality rate for the most severely injured averaged 4.8% (SE = 0.001%), and severely injured patients were nearly four times as likely to be seen in Level I or II trauma centers (relative risk = 3.9 [95% CI = 3.7 to 4.1]). The unadjusted risk ratio, based on group counts, for the association of Level I or II trauma centers with mortality was risk ratio = 4.9 (95% CI = 4.5 to 5.3); however, after sex, age, injury severity, and comorbidities were accounted for, Level I or II trauma centers were not associated with an increased risk of fatality (odds ratio = 0.96 [95% CI = 0.79 to 1.18]). There were notable changes at the extremes of age in types and causes of ED discharges for traumatic injury between 2009 and 2012. Age-stratified rates of diagnoses of traumatic brain injury increased 29.5% (SE = 2.6%) for adults older than 85 and increased 44.9% (SE = 1.3%) for children younger than 18. Firearm-related injuries increased 31.7% (SE = 0.2%) in children 5 years and younger. The total inflation-adjusted cost of ED injury care in the United States between 2006 and 2012 was $99.75 billion (SE = $0.03 billion). CONCLUSIONS: Emergency departments are a sensitive barometer of the continuing impact of traumatic injury as an important cause of morbidity and mortality in the United States. Level I or II trauma centers remain a bulwark against the tide of severe trauma in the United States, but the types and causes of traumatic injury in the United States are changing in consequential ways, particularly at the extremes of age, with traumatic brain injuries and firearm-related trauma presenting increased challenges.
