    Cardiac Output Monitoring Managing Intravenous Therapy (COMMIT) to Treat Emergency Department Patients with Sepsis
    (Wolters Kluwer, 2016-08) Hou, Peter C.; Filbin, Michael R.; Napoli, Anthony; Feldman, Joseph; Pang, Peter S.; Sankoff, Jeffrey; Lo, Bruce M.; Dickey-White, Howard; Birkhahn, Robert H.; Shapiro, Nathan I.; Department of Emergency Medicine, IU School of Medicine
    OBJECTIVE: Fluid responsiveness is proposed as a physiology-based method to titrate fluid therapy based on preload dependence. The objectives of this study were to determine if a fluid responsiveness protocol would decrease progression of organ dysfunction, and a fluid responsiveness protocol would facilitate a more aggressive resuscitation. METHODS: Prospective, 10-center, randomized interventional trial. INCLUSION CRITERIA: suspected sepsis and lactate 2.0 to 4.0 mmol/L. Exclusion criteria (abbreviated): systolic blood pressure more than 90 mmHg, and contraindication to aggressive fluid resuscitation. INTERVENTION: fluid responsiveness protocol using Non-Invasive Cardiac Output Monitor (NICOM) to assess for fluid responsiveness (>10% increase in stroke volume in response to 5 mL/kg fluid bolus) with balance of a liter given in responsive patients. CONTROL: standard clinical care. OUTCOMES: primary-change in Sepsis-related Organ Failure Assessment (SOFA) score at least 1 over 72 h; secondary-fluids administered. Trial was initially powered at 600 patients, but stopped early due to a change in sponsor's funding priorities. RESULTS: Sixty-four patients were enrolled with 32 in the treatment arm. There were no significant differences between arms in age, comorbidities, baseline vital signs, or SOFA scores (P > 0.05 for all). Comparing treatment versus Standard of Care-there was no difference in proportion of increase in SOFA score of at least 1 point (30% vs. 33%) (note bene underpowered, P = 1.0) or mean preprotocol fluids 1,050 mL (95% confidence interval [CI]: 786-1,314) vs. 1,031 mL (95% CI: 741-1,325) (P = 0.93); however, treatment patients received more fluids during the protocol (2,633 mL [95% CI: 2,264-3,001] vs. 1,002 mL [95% CI: 707-1,298]) (P < 0.001). CONCLUSIONS: In this study of a "preshock" population, there was no change in progression of organ dysfunction with a fluid responsiveness protocol. A noninvasive fluid responsiveness protocol did facilitate delivery of an increased volume of fluid. Additional properly powered and enrolled outcomes studies are needed.

    Does academic practice protect emergency physicians against burnout?
    (Wiley, 2020-12-11) Norvell, Jeffrey G.; Baker, Annalee M.; Carlberg, David J.; Diller, David; Dziedzic, Jacqueline M.; Finnell, John T.; Greenberger, Sarah; Kessler, Chad; Lo, Bruce M.; Moungey, Brooke M.; Schiller, Elizabeth; Walter, Lauren A.; Emergency Medicine, School of Medicine
    Burnout is a complex syndrome thought to result from long‐term exposure to career‐related stressors. Physicians are at higher risk for burnout than the general United States (US) working population, and emergency medicine has some of the highest burnout rates of any medical specialty. Burnout impacts physicians’ quality of life, but it can also increase medical errors and negatively affect patient safety. Several studies have reported lower burnout rates and higher job satisfaction in academic medicine as compared with private practice. However, researchers have only begun to explore the factors that underlie this protective effect. This paper aims to review existing literature to identify specific aspects of academic practice in emergency medicine that may be associated with lower physician burnout rates and greater career satisfaction. Broadly, it appears that spending time in the area of emergency medicine one finds most meaningful has been associated with reduced physician burnout. Certain non‐clinical academic work, including involvement in research, leadership, teaching, and mentorship, have been identified as specific activities that may protect against burnout and contribute to higher job satisfaction. Given the epidemic of physician burnout, hospitals and practice groups have a responsibility to address burnout, both by prevention and by early recognition and support. We discuss methods by which organizations can actively foster physician well‐being and provide examples of 2 leading academic institutions that have developed comprehensive programs to promote physician wellness and prevent burnout.
