RESUMEN
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.

INTRODUCTION: The endpoint of resuscitative interventions after traumatic injury resulting in cardiopulmonary arrest varies across institutions and even among providers. The purpose of this study was to examine survival characteristics in patients suffering torso trauma with no recorded vital signs (VS) in the emergency department (ED). METHODS: The National Trauma Data Bank was analyzed from 2007 to 2015. Inclusion criteria were patients with blunt and penetrating torso trauma without VS in the ED. Patients with head injuries, transfers from other hospitals, or those with missing values were excluded. The characteristics of survivors were evaluated, and statistical analyses performed. RESULTS: A total of 24,191 torso trauma patients without VS were evaluated in the ED and 96.6% were declared dead upon arrival. There were 246 survivors (1%), and 73 (0.3%) were eventually discharged home. Of patients who responded to resuscitation (812), the survival rate was 30.3%. Injury severity score (ISS), penetrating mechanism (odds ratio [OR] 1.99), definitive chest (OR 1.59) and abdominal surgery (OR 1.49) were associated with improved survival. Discharge to home (or police custody) was associated with lower ISS (OR 0.975) and shorter ED time (OR 0.99). CONCLUSION: Over a recent nine-year period in the United States, nearly 25,000 trauma patients were treated at trauma centers despite lack of VS. Of these patients, only 73 were discharged home. A trauma center would have to attempt over one hundred resuscitations of traumatic arrests to save one patient, confirming previous reports that highlight a grave prognosis. This creates a dilemma in treatment for front line workers and physicians with resource utilization and consideration of safety of exposure, particularly in the face of COVID-19.

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.

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: 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.
RESUMEN
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.

BACKGROUND: Current staging systems do not specifically address cutaneous adnexal carcinomas with eccrine differentiation. Due to their rarity, prognosis and management strategies are not well established. A population-based study was performed to determine prognostic factors and survival. METHODS: Patients diagnosed with cutaneous adnexal carcinomas with eccrine differentiation were identified using the surveillance, epidemiology, and end results population-based cancer registry. Associations between risk factors, treatment modalities, and survival were calculated using logistical regression, Kaplan-Meier estimates and log-rank analysis. RESULTS: The incidence of distinct eccrine subtypes was determined within 1,045 patients with cutaneous adnexal tumors containing eccrine differentiation. All-cause 5-year survival (OS) was 82%, while age-adjusted survival was 94%. Patients with microcystic adnexal carcinoma had improved OS (90%) compared to patients with hidradenocarcinoma (74%), spiradenocarcinoma (77%), porocarcinoma (79%), and eccrine adenocarcinoma (81%). The majority of patients were treated with surgical excision and a small subset with surgery plus radiation, with similar OS. Patients with well-to-moderately differentiated tumors demonstrated improved OS compared to those with poorly differentiated/anaplastic disease. CONCLUSIONS: Histological subtype and grade were associated with survival, and should be specified in biopsies and excised specimens. Surgical excision is appropriate, and the addition of adjuvant radiation may not be associated with survival. These results highlight survival data and high-risk prognostic factors that warrant prospective validation, and may augment current staging systems.
