Implementation of a Virtual Interprofessional ICU Learning Collaborative: Successes, Challenges, and Initial Reactions From the Structured Team-Based Optimal Patient-Centered Care for Virus COVID-19 Collaborators.

Initial Society of Critical Care Medicine Discovery Viral Infection and Respiratory illness Universal Study (VIRUS) Registry analysis suggested that improvements in critical care processes offered the greatest modifiable opportunity to improve critically ill COVID-19 patient outcomes. OBJECTIVES: The Structured Team-based Optimal Patient-Centered Care for Virus COVID-19 ICU Collaborative was created to identify and speed implementation of best evidence based COVID-19 practices. DESIGN SETTING AND PARTICIPANTS: This 6-month project included volunteer interprofessional teams from VIRUS Registry sites, who received online training on the Checklist for Early Recognition and Treatment of Acute Illness and iNjury approach, a structured and systematic method for delivering evidence based critical care. Collaborators participated in weekly 1-hour videoconference sessions on high impact topics, monthly quality improvement (QI) coaching sessions, and received extensive additional resources for asynchronous learning. MAIN OUTCOMES AND MEASURES: Outcomes included learner engagement, satisfaction, and number of QI projects initiated by participating teams. RESULTS: Eleven of 13 initial sites participated in the Collaborative from March 2, 2021, to September 29, 2021. A total of 67 learners participated in the Collaborative, including 23 nurses, 22 physicians, 10 pharmacists, nine respiratory therapists, and three nonclinicians. Site attendance among the 11 sites in the 25 videoconference sessions ranged between 82% and 100%, with three sites providing at least one team member for 100% of sessions. The majority reported that topics matched their scope of practice (69%) and would highly recommend the program to colleagues (77%). A total of nine QI projects were initiated across three clinical domains and focused on improving adherence to established critical care practice bundles, reducing nosocomial complications, and strengthening patient- and family-centered care in the ICU. Major factors impacting successful Collaborative engagement included an engaged interprofessional team; an established culture of engagement; opportunities to benchmark performance and accelerate institutional innovation, networking, and acclaim; and ready access to data that could be leveraged for QI purposes. CONCLUSIONS AND RELEVANCE: Use of a virtual platform to establish a learning collaborative to accelerate the identification, dissemination, and implementation of critical care best practices for COVID-19 is feasible. Our experience offers important lessons for future collaborative efforts focused on improving ICU processes of care.

Delivering a Novel Medical Education "Escape Room" at a National Scientific Conference: First Live, Then Pivoting to Remote Learning Because of COVID-19.

Escape Rooms are gaining prominence as education modalities; the use of principles of game design have been shown to augment knowledge acquisition in a fun, team-based learning experience ("edutainment"). In this report, we outline some of the medical literature and then provide our step-by-step approach and lessons learned when building what was, to our knowledge, the first continuing medical education Escape Room at a national scientific meeting. We then comment on how this innovative educational offering was reimagined the following year for remote (virtual) learning because of the COVID-19 pandemic.

Clinical and Histopathologic Features of Immune Checkpoint Inhibitor-related Pneumonitis.

Immune checkpoint inhibitors (ICIs) have revolutionized oncology, but are associated with immune-related adverse events. Clinically, pneumonitis is a well-recognized complication, but its histopathologic features are poorly understood. Institutional archives were searched for patients having ICI therapy and subsequent lung tissue sampling. After excluding infectious cases, 9 patients (5 women, median: 59 y) were identified with clinically suspected ICI-related pneumonitis. Clinical history, imaging, and pathology slides were reviewed. Patients received pembrolizumab (6 cases), nivolumab (1), ipilimumab followed by pembrolizumab (1), or pembrolizumab followed by nivolumab (1); the latter experienced pneumonitis with both agents. Treatment duration ranged from 1 to 33 cycles (median: 8). Three patients received concurrent chemotherapy and 1 received radiation; the remainder received ICI monotherapy. Symptoms were nonspecific; 2 patients were asymptomatic. Thoracic imaging showed bilateral ground glass or nodular opacities in all cases, often with pleural effusion. Histologically, organizing pneumonia was seen in 7 patients, all with subclinical or mild disease, admixed with vague non-necrotizing airspace granulomas in 3 cases; all 6 patients with follow-up did well. One patient had acute fibrinous pneumonitis and 1 had diffuse alveolar damage; both died. All 9 cases showed foamy macrophages and pneumocyte vacuolization; 6 had rare eosinophils. ICI-related pneumonitis presents as bilateral ground-glass opacities or nodules, and usually manifests as organizing pneumonia histopathologically, often with vague non-necrotizing airspace granulomas. Foamy macrophages and pneumocyte vacuolization are characteristic and rare eosinophils are often seen. Less commonly, acute fibrinous pneumonitis or diffuse alveolar damage can occur, which may be fatal.

Left Ventricular global longitudinal strain predicts heart failure readmission in acute decompensated heart failure.

BACKGROUND: The goal of this study was to determine if left ventricular (LV) global longitudinal strain (GLS) predicts heart failure (HF) readmission in patients with acute decompensated heart failure. METHODS AND RESULTS: Two hundred ninety one patients were enrolled at the time of admission for acute decompensated heart failure between January 2011 and September 2013. Left ventricle global longitudinal strain (LV GLS) by velocity vector imaging averaged from 2, 3 and 4-chamber views could be assessed in 204 out of 291 (70%) patients. Mean age was 63.8 ± 15.2 years, 42% of the patients were males and 78% were African American or Hispanic. Patients were followed until the first HF hospital readmission up to 44 months. Patients were grouped into quartiles on the basis of LV GLS. Kaplan-Meier curves showed significantly higher readmission rates in patients with worse LV GLS (log-rank p < 0.001). After adjusting for age, sex, history of ischemic heart disease, dementia, New York Heart Association class, LV ejection fraction, use of angiotensin converting enzyme inhibitors or angiotensin receptor blockers, systolic and diastolic blood pressure on admission and sodium level on admission, worse LV GLS was the strongest predictor of recurrent HF readmission (p < 0.001). The ejection fraction was predictive of readmission in univariate, but not in multivariate analysis. CONCLUSION: LV GLS is an independent predictor of HF readmission after acute decompensated heart failure with a higher risk of readmission in case of progressive worsening of LV GLS, independent of the ejection fraction.

Rapid measurement of total antioxidant capacity in plants.

There is growing interest in measuring the antioxidant status of plant tissues. This protocol describes the oxygen radical absorbance capacity (ORAC) assay, which measures antioxidant inhibition of peroxyl radical-induced oxidations and is a measure of total antioxidant capacity. The assay is performed in a microplate and is assessed with a 96-well multi-detection plate reader. Total antioxidant capacity of 64 experimental samples can easily be analyzed in 1 d. This assay is presented along with rapid assays for total phenolic content and total ascorbate content. Overall, these assays provide a general diagnostic tool of the antioxidant capacity in leaf tissue extracts.
