Who Is Teaching Residents in the Intensive Care Unit? Perceptions of Interprofessional Teaching at an Academic Medical Center.

Background: Teamwork is essential for high-quality care in the intensive care unit (ICU). Interprofessional education has been widely endorsed as a way of promoting collaborative practice. Interprofessional providers (IPPs), including nurses, pharmacists, and respiratory therapists (RTs), routinely participate in multidisciplinary rounds in the ICU, but their role in teaching residents at academic medical centers has yet to be characterized. Objective: To characterize perceptions of interprofessional teaching during and outside of rounds in the ICU. Methods: The authors conducted a cross-sectional survey of critical care physicians, internal medicine residents, nurses, pharmacists, and RTs across three ICUs at a tertiary academic medical center from September 2019 to March 2020. The frequency of different types of rounds contributions was rated on a Likert scale. Means and medians were compared across groups. Results: A total of 221 of 285 participants completed the survey (78% response rate). All IPPs described that they report data, provide clinical observations, and make recommendations frequently during ICU rounds, but teaching occurred infrequently (mean values, nurses = 2.9; pharmacists = 3.5; RTs = 3.7; 1 = not at all; 5 = always). Nurses were least likely to report teaching (P = 0.0017). From residents' and attendings' perspectives, pharmacists taught most frequently (mean values, 3.7 and 3.4, respectively). RTs self-report of teaching was higher than physicians' reports of RT teaching (P < 0.0001). Outside of rounds, residents reported a low frequency of teaching by nurses and RTs (means, nurses = 3.1; RTs = 3.1), but they reported a high rate of teaching by pharmacists (mean, 4.4). Conclusion: Nonphysician IPPs routinely participate in ICU rounds but teach medical trainees infrequently. Physicians' perception of IPP teaching frequency was generally lower than self-reports by IPPs. Exploring modifiers of interprofessional teaching may enhance education and collaboration.

"A Lot to Offer": Nurses as Educators for Medical Residents in an Academic Medical Center Intensive Care Unit.

INTRODUCTION: The role of fully trained interprofessional clinicians in educating residents has not been rigorously explored. The intensive care unit (ICU), where multiprofessional teamwork is essential to patient care, represents an ideal training environment in which to study this role. This study aimed to describe the practices, perceptions, and attitudes of ICU nurses regarding teaching medical residents and to identify potential targets to facilitate nurse teaching. METHODS: Using a concurrent mixed-methods approach, we administered surveys and focus groups to ICU nurses from September to November 2019 at a single, urban, tertiary, academic medical center. Survey data were analyzed with descriptive and comparative statistics. Focus group data were analyzed using the Framework method of content analysis. RESULTS: Of nurses surveyed, 75 of 96 (78%) responded. Nurses generally held positive attitudes about teaching residents, describing it as both important (52%, 36/69) and enjoyable (64%, 44/69). Nurses reported confidence in both clinical knowledge base (80%, 55/69) and teaching skills (71%, 49/69), but identified time, uncertainty about teaching topics, and trainee receptiveness as potential barriers. Ten nurses participated in focus groups. Qualitative analysis revealed three major themes: nurse-specific factors that impact teaching, the teaching environment, and facilitators of teaching. DISCUSSION: ICU nurses carry positive attitudes about teaching residents, particularly when facilitated by the attending, but this enthusiasm can be attenuated by the learning environment, unknown learner needs, and trainee attitudes. Identified facilitators of nurse teaching, including resident presence at the bedside and structured opportunities for teaching, represent potential targets for interventions to promote interprofessional teaching.

The Case for Interprofessional Teaching in Graduate Medical Education.

Interprofessional education has been promoted as a strategy to dismantle professional silos and promote collaborative patient care. Citing this, medical educators have emphasized the widespread integration of interprofessional education into undergraduate medical education curricula. However, in the current residency training environment, little reinforcement exists for principles gleaned from interprofessional education, and little is known about the role that interprofessional providers have in resident education. In this perspective, we offer the concept and practice of interprofessional teaching to bolster the benefits of interprofessional education during residency training. Interprofessional teaching, relatively unexplored and potentially underutilized, may offer many of the same benefits of interprofessional education but is more readily adapted for the graduate medical education setting. The intensive care unit, characterized by a culture of multidisciplinary teamwork and complex patient care, is an ideal setting in which to use interprofessional teaching. Prior to enthusiastically implementing interprofessional teaching interventions, careful consideration should be paid to the setting, strategies, and impact on all key stakeholders.

Lung Histopathology in Coronavirus Disease 2019 as Compared With Severe Acute Respiratory Sydrome and H1N1 Influenza: A Systematic Review.

BACKGROUND: Patients with severe coronavirus disease 2019 (COVID-19) have respiratory failure with hypoxemia and acute bilateral pulmonary infiltrates, consistent with ARDS. Respiratory failure in COVID-19 might represent a novel pathologic entity. RESEARCH QUESTION: How does the lung histopathology described in COVID-19 compare with the lung histopathology described in SARS and H1N1 influenza? STUDY DESIGN AND METHODS: We conducted a systematic review to characterize the lung histopathologic features of COVID-19 and compare them against findings of other recent viral pandemics, H1N1 influenza and SARS. We systematically searched MEDLINE and PubMed for studies published up to June 24, 2020, using search terms for COVID-19, H1N1 influenza, and SARS with keywords for pathology, biopsy, and autopsy. Using PRISMA-Individual Participant Data guidelines, our systematic review analysis included 26 articles representing 171 COVID-19 patients; 20 articles representing 287 H1N1 patients; and eight articles representing 64 SARS patients. RESULTS: In COVID-19, acute-phase diffuse alveolar damage (DAD) was reported in 88% of patients, which was similar to the proportion of cases with DAD in both H1N1 (90%) and SARS (98%). Pulmonary microthrombi were reported in 57% of COVID-19 and 58% of SARS patients, as compared with 24% of H1N1 influenza patients. INTERPRETATION: DAD, the histologic correlate of ARDS, is the predominant histopathologic pattern identified in lung pathology from patients with COVID-19, H1N1 influenza, and SARS. Microthrombi were reported more frequently in both patients with COVID-19 and SARS as compared with H1N1 influenza. Future work is needed to validate this histopathologic finding and, if confirmed, elucidate the mechanistic underpinnings and characterize any associations with clinically important outcomes.

Management of Sedation and Analgesia in Critically Ill Patients Receiving Long-Acting Naltrexone Therapy for Opioid Use Disorder.

The explosion of the opioid epidemic in the United States and across the world has been met with advances in pharmacologic therapy for the treatment of opioid use disorder. Long-acting naltrexone is a promising strategy, but its use has important implications for critical care, as it may interfere with or complicate sedation and analgesia. Currently, there are two available formulations of long-acting naltrexone, which are distinguished by different administration routes and distinct pharmacokinetics. The use of long-acting naltrexone may be identified through a variety of strategies (such as physical examination, laboratory testing, and medical record review), and is key to the safe provision of sedation and analgesia during critical illness. Perioperative experience caring for patients receiving long-acting naltrexone informs management in the intensive care unit. Important lessons include the use of multimodal analgesia strategies and anticipating patients' demonstrating variable sensitivity to opioids. For the critically ill patient, however, there are important distinctions to emphasize, including changes in drug metabolism and medication interactions. By compiling and incorporating the currently available literature, we provide critical care physicians with recommendations for the sedation and analgesia for critically ill patients receiving long-acting naltrexone therapy.

The Fast Literature Assessment and Review (FLARE) Initiative. A Collaborative Effort for Timely Literature Appraisal during the Coronavirus Disease Pandemic.

The emergence and worldwide spread of severe acute respiratory syndrome coronavirus 2 (SARS-CoV-2) has caused major disruptions to the healthcare system and medical education. In response, the scientific community has been acquiring, releasing, and publishing data at a remarkable pace. At the same time, medical practitioners are taxed with greater professional duties than ever before, making it challenging to stay current with the influx of medical literature.To address the above mismatch between data release and provider capacity and to support our colleagues, physicians at the Massachusetts General Hospital have engaged in an electronic collaborative effort focused on rapid literature appraisal and dissemination regarding SARS-CoV-2 with a focus on critical care.Members of the Division of Pulmonary and Critical Care, the Division of Cardiology, and the Department of Medicine at Massachusetts General Hospital established the Fast Literature Assessment and Review (FLARE) team. This group rapidly compiles, appraises, and synthesizes literature regarding SARS-CoV-2 as it pertains to critical care, relevant clinical questions, and anecdotal reports. Daily, FLARE produces and disseminates highly curated scientific reviews and opinion pieces, which are distributed to readers using an online newsletter platform.Interest in our work has escalated rapidly. FLARE was quickly shared with colleagues outside our division, and, in a short time, our audience has grown to include more than 4,000 readers across the globe.Creating a collaborative group with a variety of expertise represents a feasible and acceptable way of rapidly appraising, synthesizing, and communicating scientific evidence directly to frontline clinicians in this time of great need.

A Retrospective Review of Angiotensin II Use in Adult Patients With Refractory Distributive Shock.

PURPOSE: Catecholamines are first-line vasopressors for hemodynamic support in distributive shock but are associated with adverse effects, which may be mitigated with noncatecholamine vasopressors. Angiotensin II (ATII) is a noncatecholamine vasopressor recently approved for the management of distributive shock, but limited data support its clinical utility. The purpose of this study was to describe our institution's usage of ATII including patient outcomes (eg, response to therapy, safety profile). MATERIALS AND METHODS: Patients who received ATII at our institution were included. Patient demographics, degree of concordance with institutional ATII use guidelines, safety profile of ATII, and response to therapy (1 and 3 hours after ATII initiation) were collected. RESULTS: A total of 16 patients received ATII for distributive shock. The median Sequential Organ Failure Assessment score at the time of ATII initiation was 16.5 (interquartile range: 15.8-20.0). Fourteen (87.5%) patients met institutional guidelines for ATII use; 10 (62.5%) and 8 (50.0%) patients met our definition for response at 1 and 3 hours, respectively. No patients developed thrombotic or infectious complications after receiving ATII. CONCLUSIONS: In this cohort, ATII appears to be well tolerated in patients with a high predicted mortality. Future studies evaluating the clinical efficacy of ATII are needed to determine its role in the management of distributive shock.

Severe pulmonary toxicity from immune checkpoint inhibitor treated successfully with intravenous immunoglobulin: Case report and review of the literature.

Immune checkpoint inhibitors are known to cause a variety of immune-related adverse events, including pneumonitis. When symptomatic, treatment typically consists of temporary or permanent cessation of the checkpoint inhibitor and several weeks of corticosteroid therapy. However, a subset of patients may suffer from severe pneumonitis, and the optimal treatment for this group is not known. Here we describe the case of a patient receiving pembrolizumab for non-small cell lung cancer who developed severe checkpoint inhibitor pneumonitis. After treatment with high-dose corticosteroids failed to produce a response, a course of intravenous immunoglobulin catalyzed rapid and durable improvement. In this review, we discuss the current evidence regarding the incidence and outcomes of severe checkpoint inhibitor pneumonitis and propose a role for intravenous immunoglobulin as a possible treatment strategy.

Spaced education in medical residents: An electronic intervention to improve competency and retention of medical knowledge.

BACKGROUND: Spaced education is a novel method that improves medical education through online repetition of core principles often paired with multiple-choice questions. This model is a proven teaching tool for medical students, but its effect on resident learning is less established. We hypothesized that repetition of key clinical concepts in a "Clinical Pearls" format would improve knowledge retention in medical residents. METHODS: This study investigated spaced education with particular emphasis on using a novel, email-based reinforcement program, and a randomized, self-matched design, in which residents were quizzed on medical knowledge that was either reinforced or not with electronically-administered spaced education. Both reinforced and non-reinforced knowledge was later tested with four quizzes. RESULTS: Overall, respondents incorrectly answered 395 of 1008 questions (0.39; 95% CI, 0.36-0.42). Incorrect response rates varied by quiz (range 0.34-0.49; p = 0.02), but not significantly by post-graduate year (PGY1 0.44, PGY2 0.33, PGY3 0.38; p = 0.08). Although there was no evidence of benefit among residents (RR = 1.01; 95% CI, 0.83-1.22; p = 0.95), we observed a significantly lower risk of incorrect responses to reinforced material among interns (RR = 0.83, 95% CI, 0.70-0.99, p = 0.04). CONCLUSIONS: Overall, repetition of Clinical Pearls did not statistically improve test scores amongst junior and senior residents. However, among interns, repetition of the Clinical Pearls was associated with significantly higher test scores, perhaps reflecting their greater attendance at didactic sessions and engagement with Clinical Pearls. Although the study was limited by a low response rate, we employed test and control questions within the same quiz, limiting the potential for selection bias. Further work is needed to determine the optimal spacing and content load of Clinical Pearls to maximize retention amongst medical residents. This particular protocol of spaced education, however, was unique and readily reproducible suggesting its potential efficacy for intern education within a large residency program.

Clofarabine-associated acute kidney injury in patients undergoing hematopoietic stem cell transplant.

Abstract We examined clofarabine pharmacokinetics and association with renal toxicity in 62 patients participating in a phase I-II study of clofarabine-melphalan-alemtuzumab conditioning for hematopoietic stem cell transplant (HSCT). Pharmacokinetic parameters, including clofarabine area under the concentration-time curve (AUC), maximum concentration and clearance, were measured, and patients were monitored for renal injury. All patients had normal pretreatment creatinine values, but over half (55%) experienced acute kidney injury (AKI) after clofarabine administration. Age was the strongest predictor of AKI, with older patients at greater risk (p = 0.002). Clofarabine AUC was higher in patients who developed AKI, and patients with the highest dose-normalized AUCs experienced the most severe grades of AKI (p = 0.01). Lower baseline renal function, even when normal, was associated with lower clofarabine clearance (p = 0.008). These data suggest that renal-adjustment of clofarabine dosing should be considered for older and at-risk patients even when renal function is ostensibly normal.

Enabling a microfluidic immunoassay for the developing world by integration of on-card dry reagent storage.

As part of an effort to create a point-of-care diagnostic system for the developing world, we present a microfluidic flow-through membrane immunoassay with on-card dry reagent storage. By preserving reagent function, the storage and reconstitution of anhydrous reagents enables the devices to remain viable in challenging, unregulated environmental conditions. The assay takes place on a disposable laminate card containing both a porous membrane patterned with capture molecules and a fibrous pad containing an anhydrous analyte label. To conduct the assay, the card is placed in an external pumping and imaging instrument capable of delivering sample and rehydrated reagent to the assay membrane at controlled flow rates to generate quantitative results. Using the malarial antigen Plasmodium falciparum histidine-rich protein II (PfHRP2) as a model, we demonstrate selection of dry storage conditions, characterization of reagent rehydration, and execution of an automated on-card assay. Gold-antibody conjugates dried in a variety of sugar matrices were shown to retain 80-96% of their activity after 60 days of storage at elevated temperatures, and the release profile of the reconstituted reagent was characterized under flow in microfluidic channels. The system gave a detection limit in the sub-nanomolar range in under nine minutes, showing the potential to expand into quantitative, multi-analyte analysis of human blood samples.
