Clinicians’ Perceptions of Telemedicine for Conducting Family Conferences Prior to Transfer to a Tertiary Care Center Intensive Care Unit
Objectives: Critically ill patients are often transferred from rural to tertiary care medical centres for further higher levels of care. The transportation process may delay family conferences during which prognosis and goals of care are discussed. These conferences typically occur when family members meet the treating physicians for the first time in person after transport. Telemedicine is a tool that may be used to bridge this gap in communication by enabling these family conferences before transport. There are no data on perceptions of telemedicine used in this setting. We conducted a qualitative study assessing provider perceptions regarding the use of telemedicine for conducting family conferences prior to transport. Methods: Critical care physicians and nurses were invited to view an educational video demonstrating the process of conducting a family conference via telemedicine. Immediately following viewing of the video, physicians and nurses filled out an open-ended questionnaire regarding their thoughts and perceptions of the video and the telemedicine family conference approach. Results: There was a 68% response rate to the surveys. Responses were categorised into two major themes: benefits and barriers. Within the theme of benefits, three sub-themes were identified: satisfaction, knowledge and quality of care. We identified four domains within the theme of barriers: time, perception, technology and logistics. Conclusions: Respondents believe that there may be several benefits including increased satisfaction, improved communication and empowerment of families by dissemination of knowledge. Barriers to the use of this intervention identified include costs, time, technology and negative perceptions of the telemedicine conference
Effect of angiotensin-converting enzyme inhibitor and angiotensin receptor blocker initiation on organ support-free days in patients hospitalized with COVID-19
IMPORTANCE Overactivation of the renin-angiotensin system (RAS) may contribute to poor clinical outcomes in patients with COVID-19.
Objective To determine whether angiotensin-converting enzyme (ACE) inhibitor or angiotensin receptor blocker (ARB) initiation improves outcomes in patients hospitalized for COVID-19.
DESIGN, SETTING, AND PARTICIPANTS In an ongoing, adaptive platform randomized clinical trial, 721 critically ill and 58 non–critically ill hospitalized adults were randomized to receive an RAS inhibitor or control between March 16, 2021, and February 25, 2022, at 69 sites in 7 countries (final follow-up on June 1, 2022).
INTERVENTIONS Patients were randomized to receive open-label initiation of an ACE inhibitor (n = 257), ARB (n = 248), ARB in combination with DMX-200 (a chemokine receptor-2 inhibitor; n = 10), or no RAS inhibitor (control; n = 264) for up to 10 days.
MAIN OUTCOMES AND MEASURES The primary outcome was organ support–free days, a composite of hospital survival and days alive without cardiovascular or respiratory organ support through 21 days. The primary analysis was a bayesian cumulative logistic model. Odds ratios (ORs) greater than 1 represent improved outcomes.
RESULTS On February 25, 2022, enrollment was discontinued due to safety concerns. Among 679 critically ill patients with available primary outcome data, the median age was 56 years and 239 participants (35.2%) were women. Median (IQR) organ support–free days among critically ill patients was 10 (–1 to 16) in the ACE inhibitor group (n = 231), 8 (–1 to 17) in the ARB group (n = 217), and 12 (0 to 17) in the control group (n = 231) (median adjusted odds ratios of 0.77 [95% bayesian credible interval, 0.58-1.06] for improvement for ACE inhibitor and 0.76 [95% credible interval, 0.56-1.05] for ARB compared with control). The posterior probabilities that ACE inhibitors and ARBs worsened organ support–free days compared with control were 94.9% and 95.4%, respectively. Hospital survival occurred in 166 of 231 critically ill participants (71.9%) in the ACE inhibitor group, 152 of 217 (70.0%) in the ARB group, and 182 of 231 (78.8%) in the control group (posterior probabilities that ACE inhibitor and ARB worsened hospital survival compared with control were 95.3% and 98.1%, respectively).
CONCLUSIONS AND RELEVANCE In this trial, among critically ill adults with COVID-19, initiation of an ACE inhibitor or ARB did not improve, and likely worsened, clinical outcomes.

Not All Critically Ill Obese Patients Are the Same: The Influence of Prior Comorbidities
How the Hospital Works: An Interdisciplinary, Systems-Based Practice Medical Student Elective
OBJECTIVES Although proficient systems-based practice is a foundational skill for physicians, how best to teach it has not been well established. An elective course for fourth-year medical students wherein participants had an immersive experience with multiple interprofessional staff was created and analyzed. The authors hypothesized that participating students and interprofessional staff would show gains in systems-based knowledge and interprofessional communication. METHODS The course was a 2-week elective experience for fourth-year medical students at the Larner College of Medicine at the University of Vermont, Burlington, VT, USA. Participants integrated into a variety of interprofessional, non-physician, and administrative roles within the hospital system. Pre- and post-elective systems-based knowledge and interprofessional communication were assessed. Participating interprofessional staff were also surveyed on their experiences RESULTS From 2019 through 2022, 14 students participated in the elective, all of whom provided data. All participating students showed a quantitative improvement in systems-based knowledge and qualitatively commented on the high value of the elective in furthering their understanding of interdisciplinary care and communication. Of the 22 participating interprofessional staff surveyed, 17 responded (response rate 77%), and data showed high satisfaction with the experience and that having students learn more about their jobs improved their own job satisfaction. CONCLUSIONS An immersive, hands-on experience with interprofessional colleagues showed dual benefits for both students and staff alike. Such an elective experience is scalable to other institutions nationally and should become a standard part of medical student curricula
Hyaluronic acid is associated with organ dysfunction in acute respiratory distress syndrome
Abstract Background Hyaluronic acid (HA), an extracellular matrix component, is degraded in response to local tissue injury or stress. In various animal models of lung injury, HA has been shown to play a mechanistic role in modulating inflammation and injury. While HA is present in the lungs of patients with acute respiratory distress syndrome (ARDS), its relationship to patient outcomes is unknown. Methods We studied 86 patients with ARDS previously enrolled in the Phase II Randomized Trial of Fish Oil in Patients with Acute Lung Injury (NCT00351533) at five North American medical centers. We examined paired serum and bronchoalveolar lavage fluid (BALF) samples obtained within 48 hours of diagnosis of ARDS. We evaluated the association of HA levels in serum and BALF with local (lung injury score (LIS)) and systemic (sequential organ failure assessment score (SOFA)) measures of organ dysfunction with regression analysis adjusting for age, sex, race, treatment group, and risk factor for ARDS. Results We found that both day-0 circulating and alveolar levels of HA were associated with worsening LIS (p = 0.04 and p = 0.003, respectively), particularly via associations with degree of hypoxemia (p = 0.02 and p < 0.001, respectively) and set positive end-expiratory pressure (p = 0.01 and p = 0.02, respectively). Circulating HA was associated with SOFA score (p < 0.001), driven by associations with the respiratory (p = 0.02), coagulation (p < 0.001), liver (p = 0.006), and renal (p = 0.01) components. Notably, the alveolar HA levels were associated with the respiratory component of the SOFA score (p = 0.003) but not the composite SOFA score (p = 0.27). Conclusions Elevated alveolar levels of HA are associated with LIS while circulating levels are associated with both lung injury and SOFA scores. These findings suggest that HA has a potential role in both local and systemic organ dysfunction in patients with ARDS
