Stressors contributing to burnout among acute care and trauma surgery care teams: a systems-analysis approach.
Trauma Surg Acute Care Open
January 2025
Background: Burnout negatively impacts healthcare professionals' well-being, leading to an increased risk of human errors and patient harm. There are limited assessments of burnout and associated stressors among acute care and trauma surgery teams.
Methods: Acute care and trauma surgery team members at a US academic medical center were administered a survey that included a 2-item Maslach Burnout Inventory and 21 workplace stressors based on the National Academy of Medicine's systems model of clinician burnout and professional well-being.
Background: The Modified Nutritional Risk in Critically Ill (mNUTRIC) score has been proposed as a tool to identify hospitalized patients at risk for malnutrition who may benefit from early enteral nutrition (EN) therapy.
Objective: Our goal was to determine if mNUTRIC scores could predict, at time of intensive care unit admission, which mechanically ventilated trauma patients were at risk for malnutrition and might benefit from early EN, as indicated by reduced mortality.
Methods: We conducted a retrospective chart review of all adult trauma patients requiring mechanical ventilation for at least 48 hours between 01/21/2012 and 12/31/2016, reviewing inpatient medical records, demographic data, disease markers, injury severity, and comorbidities.
Article Synopsis
- - The study measured the second-order rate constants (k) for how eight model sulfoxides react with hypochlorous acid (HOCl), finding values between 2.7 and 5.8 × 10 M s, indicating varying reactivity among the sulfoxides.
- - A strong linear correlation (R = 0.89) was established using quantitative structure-activity relationships (QSAR) with Taft σ* constants, suggesting that the reactions are primarily driven by HOCl, with minimal impact from other chlorine species in typical water treatment settings.
- - Various analytical techniques revealed that major transformation products from these reactions include sulfones and Cl-substituted sulfoxides, and it was found that sul
Background: There is a need for improved methodologies on how to longitudinally analyze, interpret and learn from the Surveys on Patient Safety Culture™ (SOPS), developed by the Agency for Healthcare Research and Quality (AHRQ). Typically, SOPS quantify results by the percentage of positive responses, but this approach may miss insights from neutral or negative feedback.
Study Design: The SOPS were distributed every two years from 2011 to 2022 to all hospital staff at one academic institution from perioperative services.
Camera-Based 3D Semantic Scene Completion With Sparse Guidance Network.
IEEE Trans Image Process
October 2024
Article Synopsis
- Semantic scene completion (SSC) is a technology helping self-driving cars understand 3D environments better by predicting what’s in different parts of a scene from limited images.
- This paper introduces a new method called SGN that uses camera images to predict what's around using special techniques to work better and faster than other methods.
- Tests showed that SGN outperformed older methods and even its smaller version worked really well while using less computer power.
