Moral Distress in Radiology: Frequency, Root Causes, and Countermeasures-Results of a National Survey.

BACKGROUND. A major cause of burnout is moral distress: when one knows the right course of action but institutional constraints make the right course impossible to pursue. OBJECTIVE. The purpose of this study was to assess the frequency and severity with which radiologists experience moral distress and to explore moral distress's root causes and countermeasures. METHODS. This study entailed a national survey that evaluated moral distress in radiology. The survey incorporated the validated Moral Distress Scale for Health Care Professionals, along with additional questions. After the scale was modified for applicability to radiology, respondents were asked to assess 16 clinical scenarios in terms of frequency and severity of moral distress. On May 10, 2022, the survey was sent by e-mail to 425 members of radiology practices included on a national radiology society's quality-and-safety LISTSERV. The Measure of Moral Distress for Health Care Professionals (MMD-HP) score was calculated for each respondent as a summary measure of distress across scenarios (maximum possible score, 256). RESULTS. After 12 surveys with incomplete data were excluded, the final analysis included 93 of 425 respondents (22%). A total of 91 of 93 respondents (98%) experienced at least some moral distress for at least one scenario. A total of 17 of 93 respondents (18%) had left a clinical position due to moral distress; 26 of 93 (28%) had considered leaving a clinical position due to moral distress but did not leave. The mean MMD-HP score was 73 ± 51 (SD) for those who had left, 89 ± 47 for those who had considered leaving but did not leave, and 39 ± 35 for those who had never considered leaving (p < .001). A total of 41 of 85 respondents (48%) thought that the COVID-19 pandemic had influenced their moral distress level. Across respondents, the three scenarios with highest moral distress were related to systemic causes (higher case volume than could be read safely, high case volume preventing teaching residents, and lack of administrative action or support). The countermeasure most commonly selected to alleviate moral distress was educating leadership about sources of moral distress (71%). CONCLUSION. Moral distress is prevalent in radiology, typically relates to systemic causes, and is a reported contributor to radiologists changing jobs. CLINICAL IMPACT. Urgent action by radiology practice leadership is required to address moral distress, as radiologists commonly practice in environments contradictory to their core values as physicians.

Variability in personal protective equipment in cross-sectional interventional abdominal radiology practices.

PURPOSE: To determine institutional practice requirements for personal protective equipment (PPE) in cross-sectional interventional radiology (CSIR) procedures among a variety of radiology practices in the USA and Canada. METHODS: Members of the Society of Abdominal Radiology (SAR) CSIR Emerging Technology Commission (ETC) were sent an eight-question survey about what PPE they were required to use during common CSIR procedures: paracentesis, thoracentesis, thyroid fine needle aspiration (FNA), superficial lymph node biopsy, deep lymph node biopsy, solid organ biopsy, and ablation. Types of PPE evaluated were sterile gloves, surgical masks, gowns, surgical hats, eye shields, foot covers, and scrubs. RESULTS: 26/38 surveys were completed by respondents at 20/22 (91%) institutions. The most common PPE was sterile gloves, required by 20/20 (100%) institutions for every procedure. The second most common PPE was masks, required by 14/20 (70%) institutions for superficial and deep procedures and 12/12 (100%) institutions for ablation. Scrubs, sterile gowns, eye shields, and surgical hats were required at nearly all institutions for ablation, whereas approximately half of institutions required their use for deep lymph node and solid organ biopsy. Compared with other types of PPE, required mask and eye shield use showed the greatest increase during the SARS-CoV-2 pandemic. CONCLUSION: PPE use during common cross-sectional procedures is widely variable. Given the environmental and financial impact and lack of consensus practice, further studies examining the appropriate level of PPE are needed.

Complement activation and increased expression of Syk, mucin-1 and CaMK4 in kidneys of patients with COVID-19.

Acute and chronic kidney failure is common in hospitalized patients with COVID-19, yet the mechanism of injury and predisposing factors remain poorly understood. We investigated the role of complement activation by determining the levels of deposited complement components (C1q, C3, FH, C5b-9) and immunoglobulin along with the expression levels of the injury-associated molecules spleen tyrosine kinase (Syk), mucin-1 (MUC1) and calcium/calmodulin-dependent protein kinase IV (CaMK4) in the kidney tissues of people who succumbed to COVID-19. We report increased deposition of C1q, C3, C5b-9, total immunoglobulin, and high expression levels of Syk, MUC1 and CaMK4 in the kidneys of COVID-19 patients. Our study provides strong rationale for the expansion of trials involving the use of inhibitors of these molecules, in particular C1q, C3, Syk, MUC1 and CaMK4 to treat patients with COVID-19.

COVID-19 tissue atlases reveal SARS-CoV-2 pathology and cellular targets.

COVID-19, which is caused by SARS-CoV-2, can result in acute respiratory distress syndrome and multiple organ failure1-4, but little is known about its pathophysiology. Here we generated single-cell atlases of 24 lung, 16 kidney, 16 liver and 19 heart autopsy tissue samples and spatial atlases of 14 lung samples from donors who died of COVID-19. Integrated computational analysis uncovered substantial remodelling in the lung epithelial, immune and stromal compartments, with evidence of multiple paths of failed tissue regeneration, including defective alveolar type 2 differentiation and expansion of fibroblasts and putative TP63+ intrapulmonary basal-like progenitor cells. Viral RNAs were enriched in mononuclear phagocytic and endothelial lung cells, which induced specific host programs. Spatial analysis in lung distinguished inflammatory host responses in lung regions with and without viral RNA. Analysis of the other tissue atlases showed transcriptional alterations in multiple cell types in heart tissue from donors with COVID-19, and mapped cell types and genes implicated with disease severity based on COVID-19 genome-wide association studies. Our foundational dataset elucidates the biological effect of severe SARS-CoV-2 infection across the body, a key step towards new treatments.

Activation of classical and alternative complement pathways in the pathogenesis of lung injury in COVID-19.

Lung inflammation and damage is prominent in people infected with SARS-Cov-2 and a major determinant of morbidity and mortality. We report the deposition of complement components in the lungs of people who succumbed to COVID-19 consistent with the activation of the classical and the alternative pathways. Our study provides strong rationale for the expansion of trials involving the use of complement inhibitors to treat patients with COVID-19.

Vascular Disease and Thrombosis in SARS-CoV-2-Infected Rhesus Macaques.

The COVID-19 pandemic has led to extensive morbidity and mortality throughout the world. Clinical features that drive SARS-CoV-2 pathogenesis in humans include inflammation and thrombosis, but the mechanistic details underlying these processes remain to be determined. In this study, we demonstrate endothelial disruption and vascular thrombosis in histopathologic sections of lungs from both humans and rhesus macaques infected with SARS-CoV-2. To define key molecular pathways associated with SARS-CoV-2 pathogenesis in macaques, we performed transcriptomic analyses of bronchoalveolar lavage and peripheral blood and proteomic analyses of serum. We observed macrophage infiltrates in lung and upregulation of macrophage, complement, platelet activation, thrombosis, and proinflammatory markers, including C-reactive protein, MX1, IL-6, IL-1, IL-8, TNFα, and NF-κB. These results suggest a model in which critical interactions between inflammatory and thrombosis pathways lead to SARS-CoV-2-induced vascular disease. Our findings suggest potential therapeutic targets for COVID-19.

Feasibility and safety of ultrasound-guided minimally invasive autopsy in COVID-19 patients.

OBJECTIVES: To determine the feasibility and safety of ultrasound-guided minimally invasive autopsy in COVID-19 patients. METHODS: 60 patients who expired between 04/22/2020-05/06/2020 due to COVID-19 were considered for inclusion in the study, based on availability of study staff. Minimally invasive ultrasound-guided autopsy was performed with 14G core biopsies through a 13G coaxial needle. The protocol required 20 cores of the liver, 30 of lung, 12 of spleen, 20 of heart, 20 of kidney, 4 of breast, 4 of testis, 2 of skeletal muscle, and 4 of fat with total of 112 cores per patient. Quality of the samples was evaluated by number, size, histology, immunohistochemistry, and in situ hybridization for COVID-19 and PCR-measured viral loads for SARS-CoV-2. RESULTS: Five (5/60, 8%) patients were included. All approached families gave their consent for the minimally invasive autopsy. All organs for biopsy were successfully targeted with ultrasound guidance obtaining all required samples, apart from 2 patients where renal samples were not obtained due to atrophic kidneys. The number, size, and weight of the tissue cores met expectation of the research group and tissue histology quality was excellent. Pathology findings were concordant with previously reported autopsy findings for COVID-19. Highest SARS-CoV-2 viral load was detected in the lung, liver, and spleen that had small to moderate amount, and low viral load in was detected in the heart in 2/5 (40%). No virus was detected in the kidney (0/3, 0%). CONCLUSIONS: Ultrasound-guided percutaneous post-mortem core biopsies can safely provide adequate tissue. Highest SARS-CoV-2 viral load was seen in the lung, followed by liver and spleen with small amount in the myocardium.

Reorganizing Cross-Sectional Interventional Procedures Practice During the Coronavirus Disease (COVID-19) Pandemic.

OBJECTIVE. The purpose of this article is to present strategies and guidelines that can be implemented in the performance of cross-sectional interventional procedures during the coronavirus disease (COVID-19) pandemic. CONCLUSION. Radiologists who perform cross-sectional interventional procedures can take several steps to minimize the risks to patients and radiology personnel, including screening referred patients to decide which procedures can be postponed, using appropriate personal protective equipment (PPE), minimizing the number of people involved in procedures, preserving PPE when possible, and applying proper room and equipment cleaning measures.
