Analyzing the Impact of Concomitant COVID-19 Infection on Outcomes in Trauma Patients.

Background: The impact of COVID-19 infection at the time of traumatic injury remains understudied. Previous studies demonstrate that the rate of COVID-19 vaccination among trauma patients remains lower than in the general population. This study aims to understand the impact of concomitant COVID-19 infection on outcomes in trauma patients.

Does practice make perfect? The impact of hospital and surgeon volume on complications after intra-abdominal procedures.

Background: There is increasing interest in the regionalization of surgical procedures. However, evidence on the volume-outcome relationship for emergency intra-abdominal surgery is not well-synthesized. This systematic review and meta-analysis summarize evidence regarding the impact of hospital and surgeon volume on complications.

From admission to vaccination: COVID-19 vaccination patterns and their relationship with hospitalization in trauma patients.

Background: COVID-19 vaccination rates in the hospitalized trauma population are not fully characterized and may lag behind the general population. This study aimed to outline COVID-19 vaccination trends in hospitalized trauma patients and examine how hospitalization influences COVID-19 vaccination rates.

Methods: We conducted a retrospective institutional study using our trauma registry paired with the COVID-19 vaccination ENCLAVE registry.

Missing Narrative: Examining the Impact of Disability on Post-Operative Infectious Complications.

More than 20% of the population in the United States suffers from a disability, yet the impact of disability on post-operative outcomes remains understudied. This analysis aims to characterize post-operative infectious complications in patients with disability. This was a retrospective review of the National Readmission Database (2019) among patients undergoing common general surgery procedures.

Optimal dose of cryoprecipitate in massive transfusion following trauma.

Background: While cryoprecipitate (Cryo) is commonly included in massive transfusion protocols for hemorrhagic shock, the optimal dose of Cryo transfusion remains unknown. We evaluated the optimal red blood cell (RBC) to RBC to Cryo ratio during resuscitation in massively transfused trauma patients.

Methods: Adult patients in the American College of Surgeon Trauma Quality Improvement Program (2013-2019) receiving massive transfusion (≥4 U of RBCs, ≥1 U of fresh frozen plasma, and ≥1 U of platelets within 4 hours) were included.

Assessing the Relationship Between Race, Language, and Surgical Admissions in the Emergency Department.

Introduction: English proficiency and race are both independently known to affect surgical access and quality, but relatively little is known about the impact of race and limited English proficiency (LEP) on admission for emergency surgery from the emergency department (ED). Our objective was to examine the influence of race and English proficiency on admission for emergency surgery from the ED.

Methods: We conducted a retrospective observational cohort study from January 1-December 31, 2019 at a large, quaternary-care urban, academic medical center with a 66-bed ED Level I trauma and burn center.

Association of Comorbidities and Functional Level With Mortality in Geriatric Bowel Perforation.

Introduction: Spontaneous bowel perforation is associated with high morbidity and mortality. This entity remains understudied in the geriatric patient. We sought to use a national surgical sample to uncover independent predictors of mortality in elderly patients undergoing emergent operation for perforated bowel.

Balanced blood component resuscitation in trauma: Does it matter equally at different transfusion volumes?

Background: It remains unclear whether the association between balanced blood component transfusion and lower mortality is generalizable to trauma patients receiving varying transfusion volumes. We sought to study the role red blood cell transfusion volume plays in the relationships between red blood cell:platelet and red blood cell:fresh frozen plasma ratios and 4-hour mortality.

Methods: Adult patients in the 2013 to 2018 American College of Surgeons Trauma Quality Improvement Program database receiving ≥6 red blood cell, ≥1 platelet, and ≥1 fresh frozen plasma within 4 hours were included.

Angioembolization in Severe Pelvic Trauma is Associated with Venous Thromboembolism.

Introduction: Management of hemorrhage from pelvic fractures is complex and requires multidisciplinary attention. Pelvic angioembolization (AE) has become a key intervention to aid in obtaining definitive hemorrhage control. We hypothesized that pelvic AE would be associated with an increased risk of venous thromboembolism (VTE).

Preperitoneal Pelvic Packing is Associated With Increased Risk of Venous Thromboembolism.

Introduction: Preperitoneal pelvic packing (PPP) is an important intervention for control of severe pelvic hemorrhage in blunt trauma patients. We hypothesized that PPP is associated with an increased incidence of deep vein thrombosis (DVT) and pulmonary embolism (PE).

Methods: A retrospective cohort analysis of blunt trauma patients with severe pelvic fractures (AIS ≥4) using the 2015-2017 American College of Surgeons-Trauma Quality Improvement Program database was performed.

Prehospital extremity tourniquet placements-performance evaluation of non-EMS placement of a lifesaving device.

Background: The education of civilians and first responders in prehospital tourniquet (PT) utilization has spread rapidly. We aimed to describe trends in emergency medical services (EMS) and non-EMS PT utilization, and their ability to identify proper clinical indications and to appropriately apply tourniquets in the field.

Methods: A retrospective cohort study was conducted to evaluate all adult patients with PTs who presented at two Level I trauma centers between January 2015 and December 2019.

Planning for the Next Pandemic: Trauma Injuries Require Pre-COVID-19 Levels of High-Intensity Resources.

As hospital systems plan for health care utilization surges and stress, understanding the necessary resources of a trauma system is essential for planning capacity. We aimed to describe trends in high-intensity resource utilization (operating room [OR] usage and intensive care unit [ICU] admissions) for trauma care during the initial months of the COVID-19 pandemic. Trauma registry data (2019 pre-COVID-19 and 2020 COVID-19) were collected retrospectively from 4 level I trauma centers.

Do not forget the platelets: The independent impact of red blood cell to platelet ratio on mortality in massively transfused trauma patients.

Background: Balanced blood component administration during massive transfusion is standard of care. Most literature focuses on the impact of red blood cell (RBC)/fresh frozen plasma (FFP) ratio, while the value of balanced RBC:platelet (PLT) administration is less established. The aim of this study was to evaluate and quantify the independent impact of RBC:PLT on 24-hour mortality in trauma patients receiving massive transfusion.

Adding to the story, did penetrating trauma really increase? changes in trauma patterns during the COVID-19 pandemic: A multi-institutional, multi-region investigation.

Background: Results from single-region studies suggest that stay at home orders (SAHOs) had unforeseen consequences on the volume and patterns of traumatic injury during the initial months of the Coronavirus disease 2019 (COVID-19). The aim of this study was to describe, using a multi-regional approach, the effects of COVID-19 SAHOs on trauma volume and patterns of traumatic injury in the US.

Methods: A retrospective cohort study was performed at four verified Level I trauma centers spanning three geographical regions across the United States (US).

Intensive Care Unit Volume of Sepsis Patients Does Not Affect Mortality: Results of a Nationwide Retrospective Analysis.

Background: There is little research evaluating outcomes from sepsis in intensive care units (ICUs) with lower sepsis patient volumes as compared to ICUs with higher sepsis patient volumes. Our objective was to compare the outcomes of septic patients admitted to ICUs with different sepsis patient volumes.

Materials And Methods: We included all patients from the eICU-CRD database admitted for the management of sepsis with blood lactate ≥ 2mmol/L within 24 hours of admission.

The Emergency Surgery Score is a powerful predictor of outcomes across multiple surgical specialties: Results of a retrospective nationwide analysis.

Background: The Emergency Surgery Score was recently validated in a prospective multicenter study as an accurate predictor of mortality in emergency general surgery patients. The Emergency Surgery Score is easily calculated using multiple demographic, comorbidity, laboratory, and acuity of disease variables. We aimed to investigate whether the Emergency Surgery Score can predict 30-day postoperative mortality across patients undergoing emergency surgery in multiple surgical specialties.

Development of a field artificial intelligence triage tool: Confidence in the prediction of shock, transfusion, and definitive surgical therapy in patients with truncal gunshot wounds.

Background: In-field triage tools for trauma patients are limited by availability of information, linear risk classification, and a lack of confidence reporting. We therefore set out to develop and test a machine learning algorithm that can overcome these limitations by accurately and confidently making predictions to support in-field triage in the first hours after traumatic injury.

Methods: Using an American College of Surgeons Trauma Quality Improvement Program-derived database of truncal and junctional gunshot wound (GSW) patients (aged 16-60 years), we trained an information-aware Dirichlet deep neural network (field artificial intelligence triage).

Does the Emergency Surgery Score predict failure to discharge the patient home? A nationwide analysis.

Background: The Emergency Surgery Score (ESS) is a point-based scoring system validated to predict mortality and morbidity in emergency general surgery (EGS). In addition to demographics and comorbidities, ESS accounts for the acuity of disease at presentation. We sought to examine whether ESS can predict the destination of discharge of EGS patients, as a proxy for quality of life at discharge.

Isolated rib cage fractures in the elderly: Do all patients belong to the intensive care unit? A retrospective nationwide analysis.

Background: Western Trauma Association guidelines recommend admitting patients 65 years or older with two or more rib fractures diagnosed by chest radiograph to the intensive care unit (ICU). Increased use of computed tomography has led to identification of less severe, "occult" rib fractures. We aimed to evaluate current national trends in disposition of older patients with isolated rib cage fractures and to identify characteristics of patients initially admitted to the ward who failed ward management.

Vitamin C and thiamine are associated with lower mortality in sepsis.

Background: The efficacy of vitamin C (VitC) and thiamine (THMN) in patients admitted to the intensive care unit (ICU) with sepsis is unclear. The purpose of this study was to evaluate the effect of VitC and THMN on mortality and lactate clearance in ICU patients. We hypothesized that survival and lactate clearance would be improved when treated with thiamine and/or VitC.

Outcomes in patients with gunshot wounds to the brain.

Introduction: Gunshot wounds to the brain (GSWB) confer high lethality and uncertain recovery. It is unclear which patients benefit from aggressive resuscitation, and furthermore whether patients with GSWB undergoing cardiopulmonary resuscitation (CPR) have potential for survival or organ donation. Therefore, we sought to determine the rates of survival and organ donation, as well as identify factors associated with both outcomes in patients with GSWB undergoing CPR.

Comparing Machine Learning Algorithms for Predicting Acute Kidney Injury.

Prior studies have used vital signs and laboratory measurements with conventional modeling techniques to predict acute kidney injury (AKI). The purpose of this study was to use the trend in vital signs and laboratory measurements with machine learning algorithms for predicting AKI in ICU patients. The eICU Collaborative Research Database was queried for five consecutive days of laboratory measurements per patient.
