Physician educators are often expected to direct educational programs to advance their careers in academic medicine; however, what happens when physician educators’ internal sense of being an educator does not fit with expectations? Using longitudinal qualitative data, we composed three counternarratives that illuminate agentic perspectives and actions of physician education. Our narrative analysis of longitudinal data occurred in 3 phases: organizing data from interview transcripts into time-ordered displays; weaving data into counternarratives that were edited by participants; applying O’Meara’s conceptualization of faculty agency as both strategic perspective and strategic action. For one participant, faculty agency meant grappling with misaligned values and then leaving academic medicine for a job in private practice. For another, faculty agency meant striving to return to his baseline self as an educator and then reducing clinical work so time (albeit unpaid) could be spent on educational projects. For yet another, faculty agency meant recognizing that that a program leadership role was a poor fit and opting out of that role. In sum, participants deliberated their sense of being a physician educator (strategic perspectives) and when expectations became untenable, they did what they needed to do to advance their own career (strategic action). Our findings provide counternarratives that communicate insight and possibility for how physician educators might advance alternate careers in medical education and offer dynamic ways to understand agency in academic medicine.

OBJECTIVES To evaluate the effect of providing early attending physician involvement via telemedicine to improve the decision process of rapid response teams. DESIGN Quasi-experimental; three pairs of control/intervention months: June/July; August/October; November/December. SETTING Single-center, urban, quaternary academic children's hospital with three-member rapid response team: critical care fellow or nurse practitioner, nurse, respiratory therapist. Baseline practice: rapid response team leader reviewed each evaluation with an ICU attending physician within 2 hours after return to ICU. SUBJECTS 1) Patients evaluated by rapid response team, 2) rapid response team members. INTERVENTIONS Implementation of a smartphone-based telemedicine platform to facilitate early co-assessment and disposition planning between the rapid response team at the patient's bedside and the attending in the ICU. MEASUREMENTS AND MAIN RESULTS As a marker of efficiency, the primary provider outcome was time the rapid response team spent per patient encounter outside the ICU prior to disposition determination. The primary patient outcome was percentage of patients requiring intubation or vasopressors within 60 minutes of ICU transfer. There were three pairs of intervention/removal months. In the first 2 pairs, the intervention was associated with the rapid response team spending less time on rapid response team calls (June/July: point estimate -5.24 min per call; p < 0.01; August/October: point estimate -3.34 min per call; p < 0.01). During the first of the three pairs, patients were significantly less likely to require intubation or vasopressors within 60 minutes of ICU transfer (adjusted odds ratio, 0.66; 95 CI, 0.51-0.84; p < 0.01). CONCLUSIONS Early in the study, more rapid ICU attending involvement via telemedicine was associated with rapid response team providers spending less time outside the ICU, and among patients transferred to the ICU, a significant decrease in likelihood of patients requiring vasopressors or intubation within the first 60 minutes of transfer. These findings provide evidence that early ICU attending involvement via telemedicine can improve efficiency of rapid response team evaluations.

INTRODUCTION Despite its widespread application in medical education, belonging to a single community of practice does not reflect the overall experience of physician-educators. Knowing how physician-educators find their way among different communities of practice (ie their landscape of practice) has implications for professional development but the limited description in the literature. In this longitudinal qualitative research, we explored how physicians who pursue graduate degrees in medical education navigate their landscape of practice. METHODS 11/29 physicians in one cohort of a masters in medical education programme were interviewed annually from 2016 (programme start) to 2020 (2 years post-graduation). We iteratively collected and analysed data, creating inductive codes and categorising coded data by mode of identification (engagement, imagination, alignment) and time. We organised narratives into time-ordered data matrices so that final analysis wove together mode, time and participant. RESULTS All participants consistently spoke of navigating their landscape of practice, which included the community created in the graduate programme; but that single community 'doesn't define the journey itself'. They shifted engagement from teaching individual learners to translating what they learned in the graduate programme to develop educational projects and produce scholarship. They shifted the imagination from relying on internal and external assessments to experience-inspired versions of their future self. And they shifted alignment from belonging to the graduate programme's community of practice, then belonging to different communities in their landscape of practice and ultimately focussing on communities that mattered most to them. DISCUSSION Physicians in a graduate programme in medical education navigated their dynamic landscape of practice by shifting how they engaged in medical education, as well as what they imagined and who they aligned with as physician-educators. Our work offers novel insights into how knowledgeability emerges through time as overlapping modes of identification.

Healthcare is delivered in complex systems that contain numerous teams, each composed of individuals with unique funds of knowledge, technical skills, and behaviors. Simulation is used to develop and refine the capabilities of individuals in order to optimize their ability to fulfill their roles and responsibilities, allowing them to enhance team capabilities and, in turn, system performance. Using a Functional Analysis Systems Technique (FAST) diagram as the foundation of this chapter, we identify simulation as a “how” and improving patient outcomes as the “why” for an effective healthcare system, aiding the reader in understanding how simulation can be an effective tool for developing and enhancing the skills of individual practitioners.

Objectives To explore interrupters' and interruptees' experiences of interruptions occurring during morning rounds in a PICU in an attempt to understand better how to limit interruptions that threaten patient safety. Design Qualitative ethnographic study including observations, field interviews, and in-depth interviews. Setting A 55-bed PICU in a free-standing, quaternary-care children's hospital. Subjects participants Attending physicians, fellow physicians, frontline clinicians (resident physicians and nurse practitioners), and nurses working in the PICU. Interventions Data collection occurred in two parts: 1) field observations during morning rounds with brief field interviews conducted with participants involved in an observed interruption and 2) in-depth interviews conducted with selected participants from prior field observations. Measurements and main results Data were coded using a constant comparative method with thematic analysis, clustering codes into groups, and subsequently into themes. We observed 11 rounding encounters (17 hr of observation and 48 patient encounters), conducting 25 field interviews and eight in-depth interviews. Themes included culture of interruption triage, interruption triage criteria, and barriers to interruption triage. Interruptees desired forming a culture of triage, whereby less-urgent interruptions were deferred until later or addressed through an asynchronous method; this desire was misaligned with interrupters who described ongoing interruption triage based on clinical changes, time-sensitivity, and interrupter comfort, despite not having a formal triage algorithm. Barriers to interruption triage included a lack of situational awareness and experience among interrupters and interruptees. Conclusions Interrupters and interruptees did not have a shared understanding of the culture of triage within the PICU. Although interrupters attempted to triage interruptions, no formal triage algorithm existed and interruptees did not perceive a triaging culture. Using data from this study, we created a triage algorithm that could inform future studies, potentially decrease unnecessary interruptions, and optimize information sharing for essential interruptions.

Supplemental Digital Content is available in the text., Objectives: The coronavirus disease 2019 pandemic has required that hospitals rapidly adapt workflows and processes to limit disease spread and optimize the care of critically ill children. Design and Setting: As part of our institution’s coronavirus disease 2019 critical care workflow design process, we developed and conducted a number of simulation exercises, increasing in complexity, progressing to intubation wearing personal protective equipment, and culminating in activation of our difficult airway team for an airway emergency. Patients and Interventions: In situ simulations were used to identify and rework potential failure points to generate guidance for optimal airway management in coronavirus disease 2019 suspected or positive children. Subsequent to this high-realism difficult airway simulation was a real-life difficult airway event in a patient suspected of coronavirus disease 2019 less than 12 hours later, validating potential failure points and effectiveness of rapidly generated guidance. Measurements and Main Results: A number of potential workflow challenges were identified during tabletop and physical in situ manikin-based simulations. Experienced clinicians served as participants, debriefed, and provided feedback that was incorporated into local site clinical pathways, job aids, and suggested practices. Clinical management of an actual suspected coronavirus disease 2019 patient with difficult airway demonstrated very similar success and anticipated failure points. Following debriefing and assembly of a success/failure grid, a coronavirus disease 2019 airway bundle template was created using these simulations and clinical experiences for others to adapt to their sites. Conclusions: Integration of tabletop planning, in situ simulations, and debriefing of real coronavirus disease 2019 cases can enhance planning, training, job aids, and feasible policies/procedures that address human factors, team communication, equipment choice, and patient/provider safety in the coronavirus disease 2019 pandemic era.

Background Coronary artery calcification is a significant contributor to reduced accuracy of coronary computed tomographic angiography (CTA) in the assessment of coronary artery disease severity. The aim of the current study is to assess the impact of a prototype calcium deblooming algorithm on the diagnostic accuracy of CTA. Methods 40 patients referred for invasive catheter angiography underwent CTA and invasive catheter angiography. The CTA were reconstructed using a standard soft tissue kernel (CTASTAND) and a deblooming algorithm (CTADEBLOOM). CTA studies were read with and without the deblooming algorithm blinded to the invasive coronary angiogram findings. Sensitivity, specificity, accuracy, positive predictive value and negative predictive value for the detection of stenosis ≥50% or ≥70% were evaluated using quantitative coronary angiography as the reference standard. Image quality was assessed using a 5-point scale, and the presence of image artifact recorded. Results All studies were diagnostic with 548 segments available for evaluation. Image score was 3.64 ± 0.72 with CTADEBLOOM, versus 3.56 ± 0.72 with CTASTAND (p = 0.38). CTADEBLOOM had significantly less calcium blooming artifact than CTASTAND (12.5% vs. 47.5%, p = 0.001). Based on a 50% stenosis threshold for defining significant disease, the Sensitivity/Specificity/PPV/NPV/Accuracy were 65.9/84.9/27.6/96.6/83.4 for CTADEBLOOM and 75.0/81.9/26.6/97.4/81.4 for CTASTAND using a ≥50% threshold. CTADEBLOOM specificity was significantly higher than CTASTAND (84.9% vs. 81.5%, p = 0.03), with no difference between the algorithms in sensitivity (p = 0.22), or accuracy (p = 0.15). These results remained unchanged when a stenosis threshold of ≥70% was used. Interobserver agreement was fair with both techniques (CTADEBLOOM k = 0.38, CTASTAND k = 0.37). Conclusion In this proof of concept study, coronary calcification deblooming using a prototype post-processing algorithm is feasible and reduces calcium blooming with an improvement of the specificity of the CTA exam.

High-frequency oscillatory ventilation (HFOV) is a mode of mechanical ventilation used in severe pediatric respiratory failure. Thoracic ultrasound (US) is a powerful tool for diagnosing acute pathophysiologic conditions during spontaneous respiration and conventional noninvasive and invasive mechanical ventilation. High-frequency oscillatory ventilation differs from conventional modes of ventilation in that it does not primarily use bulk flow delivery for gas exchange but, rather, a number of alternative mechanisms as the result of pressure variations oscillating around a constant distending pressure. Thoracic US has not been well described in patients receiving HFOV, and it is unclear whether the US findings for assessing thoracic pathophysiologic conditions during conventional ventilation are applicable to patients receiving HFOV. We discuss the similarities and differences of thoracic US findings in patients who are spontaneously breathing or receiving conventional ventilation compared to those in patients receiving HFOV.

Introduction Although once very uncommon, multiple primary malignant neoplasms (MPMN) are becoming an increasingly popular subject in medical literature. With 182,000 new diagnoses per annum, breast cancer is the most frequently diagnosed cancer amongst women in the United States. Colorectal cancer remains the second most commonly diagnosed cancer in females, and the third in males worldwide. Methods In order to gather literature on synchronous and metachronous occurring breast and colon cancer, we searched PubMed using keywords such as 'colorectal cancer', 'breast cancer', and 'MPMN'. We searched through case reports, case series, clinical trials, letters to the editor, and retrospective series. We included any manuscript in English published between January 1990 and January 2019. The articles featured patients who had primary colorectal cancer with primary breast cancer. Articles featuring patients with more than two malignancies or malignancies other than colorectal and breast cancer were excluded. Furthermore, any metastatic cancers were excluded as well. This narrowed our search down from over 100 manuscripts to just four. Results Fortunately, the prognosis was found to be no different for these patients with MPMN assuming diagnosis and treatment are performed in a timely fashion. Additionally, it appears that although a patient with one primary cancer is at a greater risk for the development of a second cancer, it is still an odd phenomenon and thus an unlikely occurrence. Conclusion Detection of one cancer increases the odds of detecting another cancer. Hence, it is important to consider the possibility of a synchronous tumor in a patient with a newly diagnosed colon tumor, as well as to not only consider disease recurrence when following up post-resection.
