Article Synopsis
  • The study explores the use of ECMO in trauma patients, aiming to identify risk profiles that predict survival outcomes using a large database.
  • It involves analyzing data from 1037 patients and applying machine learning to categorize them into three distinct risk profiles based on age, injury severity, and comorbidities, while noting a consistent overall mortality rate across groups.
  • The findings suggest that machine learning can enhance understanding of patient risk, potentially guiding treatment protocols and improving clinical decision-making regarding ECMO use.

Introduction: The Brain Injury Guidelines (BIG) stratify patients by traumatic brain injury (TBI) severity to provide management recommendations to reduce health care resource burden but mandates that patients on anticoagulation (AC) are allocated to the most severe tertile (BIG 3). We sought to analyze TBI patients on AC therapy using a modified BIG model to determine if this population can offer further opportunity for safe reductions in health care resource utilization.

Methods: Patients 55 years or older on AC with traumatic intracranial hemorrhage (ICH) from two centers were retrospectively stratified into BIG 1 to 3 risk groups using modified BIG criteria excluding AC as a criterion.

HIV is a chronic illness that impacts the lives of more than 1 million people in the United States. As persons living with HIV (PWH) are living longer, it is important to understand the influence that religiosity/spirituality has among middle-aged and older PWH. Compare the degree of religiosity/spirituality among middle-aged and older PWH and HIV-negative individuals, and to identify demographic, clinical, and psychosocial factors associated with religiosity/spirituality among PWH.

Background: Trauma patients are resource intensive, requiring a variety of medical and procedural interventions during hospitalization. These expenses often label trauma care as "high cost" based on gross hospital charges. We hypothesized that a financial metric built on actual costs and clinically relevant trauma patient cohorts would demonstrate a lower true cost of trauma care than the standardly reported gross hospital charges.

Introduction: The Bowel Injury Prediction Score (BIPS) is a tool for identifying patients at risk for blunt bowel and mesenteric injury (BBMI) requiring surgery. BIPS is calculated by assigning one point for each of the following: (1) WBC ≥ 17,000, (2) abdominal tenderness, and (3) injury grade ≥ 4 (mesenteric contusion or hematoma with bowel wall thickening or adjacent interloop fluid collection) on CT scan. A total score ≥ 2 is associated with BBMI requiring surgery.
