The Virtual Interview Experience: Perspectives of Pulmonary and Critical Care Fellowship Applicants.

Background: Because of the coronavirus disease (COVID-19) pandemic, graduate medical education programs adopted virtual interviews (VIs) as the default modality for the 2020 recruitment season. It is unknown whether VIs allowed applicants to effectively evaluate programs, and the best interview format for the future is unclear. Objective: To 1) assess pulmonary and critical care applicants' perceived ability to evaluate programs using VIs, 2) determine the attitudes of applicants toward the components of VIs, and 3) identify applicants' preferences for the future fellowship interview format. Methods: After the National Residency Matching Program medical subspecialty match, an electronic survey was sent to 1,067 applicants to pulmonary and critical care medicine programs asking them to compare their fellowship VI experience with their residency in-person interview (IPI) experience. Results: Three hundred six (29%) applicants responded to the survey, and 289 completed it (27%). There were 117 (40%) women and 146 (51%) White individuals. Most respondents believed that VIs hindered their ability to evaluate programs' culture, faculty-fellow relationships, location, facilities, and their own fit within the program. They believed they were able to evaluate the clinical experience, curriculum, and potential for academic development equally well compared with IPIs. The most helpful elements of VIs were the interview with the program director, meetings with the fellows, and interviews with faculty members. Less helpful elements included conference access, prerecorded program director presentations, virtual hospital and city tours, and video testimonials. One hundred twenty-three respondents (43%) chose VIs with an optional visit as their preferred future interview format, 85 (29%) chose IPIs, 54 (19%) wanted a choice between VIs and IPIs, and 27 (9%) chose VIs only. Conclusion: Most pulmonary and critical care medicine applicants preferred future interviews to include both VIs and the option of an in-person visit or interview. This study can assist programs in designing their future interview formats in a trainee-centric fashion.

Virtual Interviews and Their Effect on Cognitive Load for Graduate Medical Education Applicants and Programs.

The impact of coronavirus disease (COVID-19) has dramatically affected virtually all aspects of health care use, including patient care, research, and education. Among the groups affected were prospective applicants to graduate medical education training programs. To ensure a safe and equitable process for residency and fellowship application, multiple accrediting bodies strongly recommended that training programs conduct fellowship and residency interviews in a virtual format. With little experience in virtual interviewing, most programs, including ours, were compelled to make substantial changes to the traditional interview format. We present some of the unanticipated challenges we experienced with virtual interviewing in the context of cognitive load theory. We use cognitive load theory to highlight why the challenges existed. We also offer practical tips to minimize the cognitive load experienced with virtual interviewing so that trainees and programs alike derive maximal benefit when using virtual communication platforms.

Balancing Demands: Determinants of Burnout Reported by Fellows in Pulmonary and Critical Care Medicine.

Background: Burnout is common among physicians who care for critically ill patients and is known to contribute to worse patient outcomes. Fellows training in pulmonary and critical care medicine (PCCM) have risk factors that make them susceptible to burnout; for example, clinical environments that require increased intellectual and emotional demands with long hours. The Accreditation Council for Graduate Medical Education has recognized the increasing importance of trainee burnout and encourages training programs to address burnout. Objective: To assess factors related to training and practice that posed a threat to the well-being among fellows training in PCCM and to obtain suggestions regarding how programs can improve fellow well-being. Methods: We conducted a qualitative content analysis of data collected from a prior cross-sectional electronic survey with free-response questions of fellows enrolled in pulmonary, PCCM, and critical care medicine training programs in the United States. Fellows were asked what factors posed a threat to their well-being and what changes their training program could implement. Responses were qualitatively coded and categorized into themes using thematic analysis. Results: A total of 427 fellows (44% of survey respondents) completed at least one free-response question. The majority of respondents (60%) identified as male and white/non-Hispanic (59%). The threats to well-being and burnout were grouped into five themes: clinical burden, individual factors, team culture, limited autonomy, and program resources. Clinical burden was the most common threat discussed by fellows. Fellows highlighted factors contributing to burnout that specifically pertained to trainees including challenging interpersonal relationships with attending physicians and limited protected educational time. Fellows proposed solutions addressing clinical care, changes at the program or institution level, and organizational culture changes to improve well-being. Conclusion: This study provides insight into factors fellows report as contributors to burnout and decreased well-being in addition to investigating fellow-driven solutions toward improving well-being. These solutions may help pulmonary, PCCM, and critical care medicine program directors better address fellow well-being in the future.

A National Survey of Burnout and Depression Among Fellows Training in Pulmonary and Critical Care Medicine: A Special Report by the Association of Pulmonary and Critical Care Medicine Program Directors.

BACKGROUND: The prevalence of burnout and depressive symptoms is high among physician trainees. RESEARCH QUESTION: What is the burden of burnout and depressive symptoms among fellows training in pulmonary and critical care medicine (PCCM) and what are associated individual fellow, program, and institutional characteristics? STUDY DESIGN AND METHODS: We conducted a cross-sectional electronic survey of fellows enrolled in pulmonary, PCCM, and critical care medicine training programs in the United States to assess burnout and depressive symptoms. Burnout symptoms were measured using the Maslach Burnout Index two-item measure. The two-item Primary Care Evaluation of Mental Disorders Procedure was used to screen for depressive symptoms. For each of the two outcomes (burnout and depressive symptoms), we constructed three multivariate logistic regression models to assess individual fellow characteristics, program structure, and institutional polices associated with either burnout or depressive symptoms. RESULTS: Five hundred two of the 976 fellows who received the survey completed it-including both outcome measures-giving a response rate of 51%. Fifty percent of fellows showed positive results for either burnout or depressive symptoms, with 41% showing positive results for depressive symptoms, 32% showing positive results for burnout, and 23% showing positive results for both. Reporting a coverage system in the case of personal illness or emergency (adjusted OR [aOR], 0.44; 95% CI, 0.26-0.73) and access to mental health services (aOR, 0.14; 95% CI, 0.04-0.47) were associated with lower odds of burnout. Financial concern was associated with higher odds of depressive symptoms (aOR, 1.13; 95% CI, 1.05-1.22). Working more than 70 hours in an average clinical week and the burdens of electronic health record (EHR) documentation were associated with a higher odds of both burnout and depressive symptoms. INTERPRETATION: Given the high prevalence of burnout and depressive symptoms among fellows training in PCCM, an urgent need exists to identify solutions that address this public health crisis. Strategies such as providing an easily accessible coverage system, access to mental health resources, reducing EHR burden, addressing work hours, and addressing financial concerns among trainees may help to reduce burnout or depressive symptoms and should be studied further by the graduate medical education community.

Salvage therapies for refractory hypoxemia in ARDS.

Acute Respiratory Distress Syndrome (ARDS) is a condition of varied etiology characterized by the acute onset (within 1 week of the inciting event) of hypoxemia, reduced lung compliance, diffuse lung inflammation and bilateral opacities on chest imaging attributable to noncardiogenic (increased permeability) pulmonary edema. Although multi-organ failure is the most common cause of death in ARDS, an estimated 10-15% of the deaths in ARDS are caused due to refractory hypoxemia, i.e.- hypoxemia despite lung protective conventional ventilator modes. In these cases, clinicians may resort to other measures with less robust evidence -referred to as "salvage therapies". These include proning, 48 h of paralysis early in the course of ARDS, various recruitment maneuvers, unconventional ventilator modes, inhaled pulmonary vasodilators, and Extracorporeal membrane oxygenation (ECMO). All the salvage therapies described have been associated with improved oxygenation, but with the exception of proning and 48 h of paralysis early in the course of ARDS, none of them have a proven mortality benefit. Based on the current evidence, no salvage therapy has been shown to be superior to the others and each of them is associated with its own risks and benefits. Hence, the order of application of these therapies varies in different institutions and should be applied following a risk-benefit analysis specific to the patient and local experience. This review explores the rationale, evidence, advantages and risks behind each of these strategies.

Modeling of Lung Function Recovery in Neuralgic Amyotrophy With Diaphragm Impairment.

BACKGROUND: Neuralgic amyotrophy is an inflammatory peripheral nerve disorder in which phrenic nerve involvement can lead to diaphragm paralysis. The prevalence, magnitude, and time course of diaphragm recovery are uncertain. METHODS: This study modeled the course of recovery of lung function in 16 subjects with diaphragm impairment from neuralgic amyotrophy. The first and last available vital capacity, sitting-to-supine decline in vital capacity, and maximal inspiratory pressures were compared. RESULTS: An asymptotic regression model analysis in 11 subjects with at least partial recovery provided estimates of the vital capacity at onset (47%, 95% CI 25-68%), the final vital capacity (81%, 95% CI 62-101%), and the half-time to recovery (22 months, 95% CI 15-43 months). In those subjects, there was a significant improvement between the first and last measured FVC (median 44-66%, P = .004) and maximal inspiratory pressure (mean 34-51%, P = .004). Five subjects (31%) with complete recovery had a final sitting-to-supine drop of vital capacity of 16% and a maximal predicted inspiratory pressure of 63%. CONCLUSIONS: Sixty-nine percent of subjects with diaphragm impairment from neuralgic amyotrophy experience recovery of lung function and diaphragm strength, but recovery is slow and may be incomplete.

Pirfenidone and Nintedanib for Treatment of Idiopathic Pulmonary Fibrosis.

Idiopathic pulmonary fibrosis is one of the most common entities of the family of disorders known as the interstitial lung diseases. It is a chronic, progressive, and often-fatal disease with a median survival time of 3 to 5 years. In 2014 the US Food and Drug Administration approved pirfenidone and nintedanib, two antifibrotic agents for the treatment of idiopathic pulmonary fibrosis. Because these are the only drugs approved that can alter the course of this rare but fatal disease, this article reviews the major studies that led to the approval of these drugs and examines the indications for treatment and the expected outcomes of therapy.

Hb Grove City [ß38(C4)Thr→Ser, ACC>AGC; HBB: c.116C>G]: a new low oxygen affinity ß chain variant.

A previously unreported ß chain hemoglobin (Hb) variant, Hb Grove City [ß38(C4)Thr→Ser, ACC>AGC; HBB: c.116C>G], was discovered in a woman who presented with hypoxia and mild anemia. Her young daughter also tested positive for the variant and displayed similar symptoms. Hemoglobin-oxygen dissociation testing confirmed right-shifted oxygen dissociation curves. A corresponding Hb variant was detected by high performance liquid chromatography (HPLC) and intact mass spectrometry (MS) but was not detected by capillary electrophoresis (CE), isoelectrofocusing (IEF) or alkaline or acid electrophoresis. DNA sequencing analysis confirmed a ß-globin gene mutation. All three previous mutations at this locus affect oxygen affinity, as does this new variant. This newly described variant showed variable stability results and therefore may be mildly unstable but is not associated with microcytosis, significant hemolysis or clinically evident cyanosis. It is important to consider hemoglobinopathies in patients who are anemic and have unexplained hypoxia. Arterial blood gas and p50 evaluations may prevent unnecessary diagnostic interventions. Additionally, Hb variants with altered oxygen affinity can be electrophoretically silent; therefore, multiple methods including MS and/or DNA sequencing are warranted when clinical suspicion is high.

State of the evidence: mechanical ventilation with PEEP in patients with cardiogenic shock.

The need to provide invasive mechanical ventilatory support to patients with myocardial infarction and acute left heart failure is common. Despite the large number of patients requiring mechanical ventilation in this setting, there are remarkably few data addressing the ideal mode of respiratory support in such patients. Although there is near universal acceptance regarding the use of non-invasive positive pressure ventilation in patients with acute pulmonary oedema, there is more concern with invasive positive pressure ventilation owing to its more significant haemodynamic impact. Positive end-expiratory pressure (PEEP) is almost universally applied in mechanically ventilated patients due to benefits in gas exchange, recruitment of alveolar units, counterbalance of hydrostatic forces leading to pulmonary oedema and maintenance of airway patency. The limited available clinical data suggest that a moderate level of PEEP is safe to use in severe left ventricular (LV) dysfunction and cardiogenic shock, and may provide haemodynamic benefits as well in LV failure which exhibits afterload-sensitive physiology.

Airway pressure release ventilation: an alternative mode of mechanical ventilation in acute respiratory distress syndrome.

Acute respiratory distress syndrome (ARDS) results in collapse of alveoli and therefore poor oxygenation. In this article, we review airway pressure release ventilation (APRV), a mode of mechanical ventilation that may be useful when, owing to ARDS, areas of the lungs are collapsed and need to be reinflated ("recruited"), avoiding cyclic alveolar collapse and reopening.
