Retrospective Study of EMS Scene Times and Mortality in Penetrating Trauma Patients: Improving Transport Standards and Patient Outcomes.

BACKGROUND: This study aimed to determine the impact of emergency medical service (EMS) scene time variability on adult and pediatric trauma patient outcomes with moderate or severe penetrating injuries. METHODS: This retrospective study analyzed the American College of Surgeons (ACS) Trauma Quality Improvement Program (TQIP) database between 2017 and 2020 to evaluate the relationship between EMS scene time on adult and pediatric patients with moderate to severe injuries. Primary outcomes included Dead on Arrival (DOA) to the Emergency Department (ED), ED mortality, 24-hour mortality, and in-hospital mortality. Multivariable logistic regression models were used to examine the association of each EMS scene time category and mortality. RESULTS: Adult patients with 10-30 minutes of EMS scene time had increased odds of experiencing ED mortality, 24-hour mortality, and in-hospital mortality. Adults with >30 minutes of EMS scene time were more likely to be DOA to the ED. There was no significant association with mortality for patients with <10 minutes of EMS scene time. In the pediatric subset of patients, those with 10-30 minutes of EMS scene time were more likely to experience ED mortality and in-hospital mortality. CONCLUSION: EMS scene times less than 10 minutes were associated with the greatest odds of survival, supporting the "load and go" theory for penetrating trauma. Our study suggests that even an EMS scene time of 10-30 minutes results in a significantly increased risk of mortality, and further efforts are needed to improve scene time through improved EMS and hospital policies.

National analysis of over and under-triage rates in relation to trauma population risk factors and associated outcomes across various levels trauma centers.

INTRODUCTION: Over and under-triage represent a misallocation of resources that can affect patient outcomes. The purpose of this study is to evaluate over and under-triage rates in relation to risk factors and associated outcomes of trauma patients nationwide. METHODS: A retrospective cohort study using the Trauma Quality Improvement Program from 2017 to 2020. Multivariable regression models were used to assess predictors of over-triage (activation when unnecessary) and under-triage (limited activation when full activation was necessary). RESULTS: 22.2 % (32,782) of the study population were over-triaged and 20.3 % (29,996) were under-triaged. Most over-triaged patients were Black, with Medicaid, or had a penetrating injury, whereas most under-triaged patients were White, with private/commercial insurance, or had a blunt injury. With covariates adjusted for, Pacific Islander (p = 0.024) and American Indian patients (p = 0.015) were associated with higher odds of over-triage, and Hispanic patients had higher odds of under-triage (p<0.001). Patients with Medicare (p<0.001) had higher odds of over-triage, and patients with private/commercial insurance (p<0.001) had higher odds of under-triage compared to Medicaid patients. Patients in level II (p<0.001) and level III (p<0.001) trauma hospitals were associated with higher odds of over-triage. CONCLUSION: Pacific Islander and American Indian patients, Medicare, and level II and III trauma centers are at increased risk of over-triage rates, while Hispanic and privately insured trauma patients had a higher risk for under-triage. Future studies should further investigate factors contributing to poor outcomes linked to under-triage practices and methods to improve consistency and standardization of triage tools across various levels of trauma centers.

Trends in disparities research on trauma and acute care surgery outcomes: A 10-year systematic review of articles published in The Journal of Trauma and Acute Care Surgery.

ABSTRACT: This is a 10-year review of The Journal of Trauma and Acute Care Surgery (JTACS) literature related to health care disparities, health care inequities, and patient outcomes. A retrospective review of articles published in JTACS between January 1, 2013, and July 15, 2022, was performed. Articles screened included both adult and pediatric trauma populations. Included articles focused on patient populations related to trauma, surgical critical care, and emergency general surgery. Of the 4,178 articles reviewed, 74 met the inclusion criteria. Health care disparities related to gender (n = 10), race/ethnicity (n = 12), age (n = 14), income status (n = 6), health literacy (n = 6), location and access to care (n = 23), and insurance status (n = 13) were described. Studies published on disparities peaked in 2016 and 2022 with 13 and 15 studies respectively but dropped to one study in 2017. Studies demonstrated a significant increase in mortality for patients in rural geographical regions and in patients without health insurance and a decrease in patients who were treated at a trauma center. Gender disparities resulted in variable mortality rates and studied factors, including traumatic brain injury mortality and severity, venous thromboembolism, ventilator-associated pneumonia, firearm homicide, and intimate partner violence. Under-represented race/ethnicity was associated with variable mortality rates, with one study demonstrating increased mortality risk and three finding no association between race/ethnicity and mortality. Disparities in health literacy resulted in decreased discharge compliance and worse long-term functional outcomes. Studies on disparities in JTACS over the last decade primarily focused on location and access to health care, age, insurance status, and race, with a specific emphasis on mortality. This review highlights the areas in need of further research and funding in the Journal of Trauma and Acute Care Surgery regarding health care disparities in trauma aimed at interventions to reduce disparities in patient care, ensure equitable care, and inform future approaches targeting health care disparities. LEVEL OF EVIDENCE: Systematic Review; Level IV.

Glasgow Coma Scale Intubation Thresholds and Outcomes of Patients With Traumatic Brain Injury: The Need for Tailored Practice Management Guidelines.

INTRODUCTION: This study aims to re-evaluate the GCS threshold for intubation in patients presenting to the ED with a traumatic brain injury to optimize outcomes and provide evidence for future practice management guidelines. METHODS: We retrospectively reviewed the ACS-TQIP-Participant Use File (PUF) 2015-2019 for adult trauma patients 18 years and older who experienced a blunt traumatic head injury and received computerized tomography. Multivariable regressions were performed to assess associations between outcomes and GCS intubation thresholds of 5, 8, and 10. RESULTS: In patients with a GCS ≤5, there were no differences in mortality (GCS ≤5: 26.3% vs GCS >5: 28.3%, adjusted P = .08), complication rates (GCS ≤5: 9.1% vs GCS >5: 10.3%, adjusted P = .91), or ICU length of stay (GCS ≤5: 5.4 vs GCS >5: 4.7, adjusted P = .36) between intubated and non-intubated patients. Intubated patients at GCS thresholds ≤8 (26.2% vs 19.1%, adjusted P < .0001) and ≤10 (25.6% vs 15.8%, adjusted P < .0001) had significantly higher mortality rates than non-intubated patients. Intubation at all GCS thresholds >5 resulted in higher rates of complications, H-LOS, and ICU-LOS when compared to non-intubated patients with the same GCS score. CONCLUSION: A GCS ≤5 was the threshold at which intubation in TBI patients conferred an additional benefit in disposition without worsened outcomes of mortality, H-LOS, or ICU-LOS. Trauma societies and hospital institutions should consider revisiting existing guidelines and protocols concerning the appropriate GCS threshold for safer intubation and better outcomes among these patient population.

Analysis of Racial and Gender Distribution of US MD Graduates Entering Into General Surgery and Surgical Subspecialties Residencies: The Need for Effective & Sustainable Diversity, Equity, and Inclusion Strategies.

INTRODUCTION: We aim to investigate disparities & inequities based on race, sex, graduating age, and the number of peer-reviewed publications among allopathic U.S. Doctor of Medicine graduates who reported entering a surgical training program over a span of 5 y. METHODS: A retrospective cohort analysis of the Association of American Medical Colleges student records system and Electronic Residency Application Service for graduates entering a surgical specialty residency during graduate medical education training cycles 2015-2020. RESULTS: African American, Asian, and Hispanic applicants each accounted for less than 1% of graduates who reported entering a surgical training program. Asians (OR = 0.58, P = 0.01) and those identifying as other races (OR = 0.74, P = 0.01) were significantly less likely to enter a surgical subspecialty when compared to Caucasians. Orthopedic surgery contained the lowest proportion of minorities; African Americans 0.5% (n = 18), Asians 0.3% (n = 11), Hispanics 0.1% (n = 4), and others with 2% (n = 68). Females who reported entering Orthopedic surgery training represented the smallest female population in surgical specialties (17%, n = 527). The number of peer-reviewed publications was significantly associated with male sex (ß = 0.28, P < 0.01), age between 30 and 32 at graduation (ß = 1.76, P < 0.01), and identification as other races (ß = 1.53, P < 0.01). CONCLUSIONS: Racial minorities represented only 5.1% of graduates who reported entering a surgical specialty graduate medical education training program. Minority races and females were significantly less likely to enter a surgical subspecialty training program compared to Caucasian graduates and males, especially in orthopedic surgery. Implementation of specialty-specific programs and diversity, equity, and inclusion departments that promote mentorship and guidance toward residency programs is needed to combat continued race and sex disparities.

National analysis of motorcycle associated injuries and fatalities: Wearing helmet saves lives.

INTRODUCTION: Riding a motorcycle without a helmet represents a public health risk that can result in disabling injuries or death. We aim to provide a comprehensive analysis of the impact of helmet use on motorcycle injuries, injury types, and fatalities, to highlight areas requiring future intervention. METHODS: We performed a retrospective cohort study utilizing the American College of Surgeons Trauma Quality Program Participant Use File between 2017 and 2020 analyzing motorcycle associated injuries and fatalities in adult patients with moderate and severe injury severity score in relation to helmet use. Multivariable regressions were utilized and adjusted for potential confounders. A subset analysis was performed for patients presenting with abbreviated injury scale (AIS) head ≥3 and all other body regions ≤2. RESULTS: 43,225 patients met study criteria, of which 24,389 (56.4%) were helmet users and 18,836 (43.6%) were not. Helmet use was associated with a 35% reduction in the relative risk of expiring in the hospital due to motorcycle-related injuries (aOR 0.65; 95% CI [0.59-0.70]; p < 0.001) and a decreased intensive care unit length of stay (ICU-LOS) by half a day (B = -0.50; 95% CI [-0.77, -0.24]; p < 0.001). CONCLUSION: Motorcycle riders without a helmet had significantly greater odds of increased in-hospital mortality and longer stays in the ICU than those who used a helmet. The results of this nationwide study support the need for continued research exploring the significance of helmet use and interventions aimed at improving helmet usage among motorcyclists. LEVEL OF EVIDENCE: Prognostic and epidemiological, level III.

Analysis of Bicyclist Injuries and Fatalities in The United States: The Need for Effective & Sustainable Prevention Policies.

We aim to investigate nationwide and state trends of bicyclist injuries, fatalities, and associated costs amongst adult and pediatric populations to assess the need for effective and strategic interventions. An epidemiologic study was performed investigating the injury and fatality rate of bicyclists from 2010 to 2020. The fatality rate was higher in adults compared to pediatric bicyclists (0.36 vs. 0.12 per population of 100,000, P < .001), but pediatric bicyclists suffered higher rates of injury (246.19 vs. 102.11 per population of 100,000, P < .001). The medical cost of fatalities for adult bicyclists was $139.1 million compared to $9.0 million for pediatric bicyclists. Bicyclist fatality rates are significantly higher per capita for adult bicyclists. States including Florida, South Carolina, and Louisiana had the highest bicyclist fatalities per capita for both adults and children.

Institutional response to the 2022 iodinated contrast shortage: A narrative review.

INTRODUCTION: The iodinated contrast material (ICM) shortage of 2022 has affected healthcare systems worldwide, forcing institutions to adapt by implementing interventions to conserve ICM without compromising patient care. We aim to present the practices proven to be effective in reducing ICM consumption to improve resource allocation in trauma patients. METHODS: A literature search of PubMed, Google Scholar, and Cochrane was conducted. Studies investigating the utility of ICM in the management of trauma & emergency surgery patients, as well as institutional interventions that were implicated as a response to the ICM shortage of 2022 were included for review. RESULTS: Eight articles were selected and reviewed. The use of alternative, non-contrast-enhanced imaging modalities, particularly non-contrast-enhanced CT (NECT), was found to be effective in reducing ICM consumption. Other institutions have implemented strategies to reduce the ICM dose for each imaging study performed, including decreasing ICM dose itself as well as reducing tube voltage, which was shown to reduce ICM use by 50%. Waste minimization by splitting single-dose contrast vials into smaller aliquots utilized for multiple imaging studies has also been an effective method. Additionally, assembling a Radiology Command Center Team, responsible for monitoring ICM supplies while offering 24/7 consults regarding options for alternative imaging, has resulted in an overall reduction in contrast consumption of 50% in 7 days. CONCLUSION: In response to the ICM shortage of 2022, most healthcare institutions have found the use of alternative imaging modalities to be effective in reducing ICM consumption. Other effective measures include ICM dose reduction and ICM waste minimization.

Nationwide Analysis of Motorcycle-Associated Injuries and Fatalities in the United States: Insufficient Prevention Policies or Abandoned Laws?

BACKGROUND: Motorcycle road traffic collisions are a major cause of mortality in the United States. We aimed to analyze the temporal and statewide trends in motorcycle collision fatalities (MCFs) nationwide and their association with state laws regarding motorcycle helmet requirements, lane splitting, speeding, intoxicating driving, and red light cameras. METHODS: A retrospective review of United States MCF/capita from 2015 to 2019 was performed using the Fatality Analysis Reporting System database. MCF/capita was defined as a motorcyclist death per 100 000 motorcyclist registrations. Independent-samples t-test and ANOVA were used to determine differences, with significance defined as P < .05. Linear regression analysis and Pearson's correlation were used to further determine associations between variables. RESULTS: The majority of fatalities occurred in males (n = 21 354, 91.0%), ages 25-54 (n = 13 728, 58.5%), and Caucasians (n = 19 195, 81.8%). A total of 24 states and DC exhibited positive trends in MCF/capita from 2015 to 2019. There was no significant difference in MCF/capita between states who had mandatory helmet laws for all, partial requirements, and states with no law (63.4 vs 54.3 vs 33.6, P = .360). Among fatalities involving alcohol, a significantly greater number of MCF/capita were found above the legal limit of .08 compared to the group with a blood alcohol concentration of .01-.07 (17.8 vs 4.5, P < .001). CONCLUSION: Motorcyclist fatalities continue to pose a public health risk, with 24 states showing an upward trend. Additional interventions and laws are needed to decrease the number of motorcyclist deaths. Further strategy on implementation and enforcement of helmet laws and alcohol consumption may be an essential component.

Exercise Training Prevents the Loss of Wall Thickness and Lowers Expression of Alzheimer's Related Proteins in 3xTg Mouse Jejunum.

Growing evidence has demonstrated the benefits of regular exercise on cardiovascular, neural, and cognitive function in humans with Alzheimer's disease (AD). However, the consequences of AD on gastrointestinal morphology and the effects of regular exercise, which plays an important role against the development of certain gastrointestinal-related diseases, are still poorly understood. Therefore, to assess the changes in intestinal structure in a mouse model of AD and the impact of exercise, 2-month-old 3xTg-AD male mice were subjected to treadmill running 5 days per week for a period of 5 months. Jejunum from 3xTg-AD mice analyzed by histochemical methods revealed significant alterations in morphology. Compared to age-matched wild-type (WT) mice, villi length and crypt depth were increased, and collagen content of jejunum was elevated in 3xTg-AD mice. Jejunum wall dimensions, expressed as total wall thickness, outer longitudinal thickness, and inner circular thickness were decreased in 3xTg-AD compared to WT. Smooth muscle actin expression in jejunal wall was decreased in 3xTg-AD. Most of these aberrations were improved with exercise. Western blot expression of cyclin dependent kinase 5 (CDK5, involved in neural cell death and hyperphosphorylation of tau), was elevated in 3xTg-AD jejunum. This was associated with a 4-fold increase in tau5 expression. Exercise prevented the increase in expression of CDK5 and tau5. Expression of caspase 3 (an apoptotic marker) was elevated in 3xTg-AD jejunum and exercise prevented this. The results of our study indicate that the abnormalities in jejunum of the 3xTg mouse model of AD were prevented with exercise training.
