RESUMO

RATIONALE AND OBJECTIVES: Work-life experience of physicians is a driver of work engagement vs. burnout. We aimed to determine individual and institutional factors affecting work-life experience of the clinical faculty at a large tertiary care academic medical center. MATERIALS AND METHODS: The Department of Radiology clinical faculty (n = 62) were surveyed electronically in October 2022. Twenty-three questions, consisting of multiple choice, Yes/No, and Likert scale ratings were administered to obtain demographic information and data for life outside of work, life at work, and work-life integration for the prior 12 months. Work engagements in terms of clinical, research, administrative, and education; work practices including engagement in extra work and remote work; life responsibilities; and utilization of work-life balance strategies were analyzed for percentages and differences in seniority levels and genders. Ratings of faculty work engagement and life integration strategies were assessed utilizing a 1-5 Likert scale. Descriptive statistics were utilized to report mean, standard deviation, median, Q1 and Q3 for continuous measurements, while count and percentage for categories measurements. Comparisons between seniority and gender categories were conducted using independent t-test or Wilcoxon rank sum test depending on data normality assessed through histogram analysis. Chi-square test was used to make comparisons for categorical data. When encountered with small cell (category with <5 count), Fisher's exact test was used for 2 × 2 table analysis and Freeman-Halton test was used for comparisons with more than two categories. SAS 9.4 was used for the data analysis. RESULTS: Twenty-eight faculty (M:F = 17:11) responded to the survey (survey response rate 45%). The vast majority of faculty reported working extra hours, with 40% working at least 10 hours extra per week. Total of 42.9% reported performing clinical work in the extra hours worked. Total 70.4% of faculty had caregiver responsibilities and 64.3% reported other individual stresses (e.g., financial, family/social, health-related), which required consistent demand of time and effort. A total of 35.7% of faculty reported not being able to balance competing life and work demands. A total of 21.4% respondents reported not utilizing any individual healthy lifestyle choices on a consistent basis over the prior 12 months. Protected time off work and remote work were perceived as effective strategies to provide adequate work-life balance; however, remote work engagement was relatively minor and 35.7% bought back vacation. Total 53.6% respondents reported a level 4 (out of 5) rating for work being meaningful and being positively engaged in their work. CONCLUSION: Institutions should invest in providing the infrastructure for physician work-life balance and in facilitating healthy lifestyle choices for physicians.

RESUMO

BACKGROUND: The coronavirus disease 2019 (COVID-19) pandemic altered education, exams, and residency applications for United States medical students. AIM: To determine the specific impact of the pandemic on US medical students and its correlation to their anxiety levels. METHODS: An 81-question survey was distributed via email, Facebook and social media groups using REDCapTM. To investigate risk factors associated with elevated anxiety level, we dichotomized the 1-10 anxiety score into low (≤ 5) and high (≥ 6). This cut point represents the 25th percentile. There were 90 (29%) shown as low anxiety and 219 (71%) as high anxiety. For descriptive analyses, we used contingency tables by anxiety categories for categorical measurements with chi square test, or mean ± STD for continuous measurements followed by t-test or Wilcoxson rank sum test depending on data normality. Least Absolute Shrinkage and Selection Operator was used to select important predictors for the final multivariate model. Hierarchical Poisson regression model was used to fit the final multivariate model by considering the nested data structure of students clustered within State. RESULTS: 397 medical students from 29 states were analyzed. Approximately half of respondents reported feeling depressed since the pandemic onset. 62% of participants rated 7 or higher out of 10 when asked about anxiety levels. Stressors correlated with higher anxiety scores included "concern about being unable to complete exams or rotations if contracting COVID-19" (RR 1.34; 95%CI: 1.05-1.72, P = 0.02) and the use of mental health services such as a "psychiatrist" (RR 1.18; 95%CI: 1.01-1.3, P = 0.04). However, those students living in cities that limited restaurant operations to exclusively takeout or delivery as the only measure of implementing social distancing (RR 0.64; 95%CI: 0.49-0.82, P < 0.01) and those who selected "does not apply" for financial assistance available if needed (RR 0.83; 95%CI: 0.66-0.98, P = 0.03) were less likely to have a high anxiety. CONCLUSION: COVID-19 significantly impacted medical students in numerous ways. Medical student education and clinical readiness were reduced, and anxiety levels increased. It is vital that medical students receive support as they become physicians. Further research should be conducted on training medical students in telemedicine to better prepare students in the future for pandemic planning and virtual healthcare.

RESUMO

Antiparallel ß-sheets are important secondary structures within proteins that equilibrate with random-coil states; however, little is known about the exact dynamics of this process. Here, the first dynamic ß-sheet models that mimic this equilibrium have been designed by using an H-bond surrogate that introduces constraint and torque into a tertiary amide bond. 2D NMR data sufficiently reveal the structure, kinetics, and thermodynamics of the folding process, thereby leading the way to similar analysis in isolated biologically relevant ß-sheets.

RESUMO

OBJECTIVE: The aim of this study was to reach consensus on quality assessment of clinical information in imaging requisitions using Reason for exam Imaging Reporting and Data System (RI-RADS). METHODS: A Delphi study was conducted in September 2018 with a panel of 87 radiologists with diverse levels of experience from various settings (community hospitals, private hospitals, university hospitals, and clinics), of which 74.7% completed the survey. The agreement was assessed in the following subjects: (a) presumed effect of standardization, (b) the standardized system for information, (c) the scoring system for evaluation of requisitions, and (d) the implementation of RI-RADS. The consensus threshold was set at 51% responding (strongly) agree. The rate of lawsuits preventable with clinical information was also assessed. RESULTS: Consensus was reached on all objectives of the study with a high level of agreement. Radiologists agreed on the need for standardization of imaging requisitions and attributed it to increased speed and accuracy of interpretations. Three categories of information were determined as key indicators of quality: impression, clinical findings, and clinical question. The scoring system is intended to grade requisitions based on the presence of these categories. Radiologists also agreed that RI-RADS will encourage physicians to improve requisitions. Among radiologists who responded to the survey, 12.6% had experienced at least one lawsuit potentially preventable with sufficient information in requisitions. CONCLUSIONS: Reason for exam Imaging Reporting and Data System can be used as a standard for quality assessment of requisitions. Its use may improve the quality of patient care and reduce lawsuits against radiologists.

RESUMO

BACKGROUND: Efforts to reduce nosocomial spread of COVID-19 have resulted in unprecedented disruptions in clinical workflows and numerous unexpected stressors for imaging departments across the country. Our purpose was to more precisely evaluate these impacts on radiologists through a nationwide survey. METHODS: A 43-item anonymous questionnaire was adapted from the AO Spine Foundation's survey and distributed to 1521 unique email addresses using REDCap™ (Research Electronic Data Capture). Additional invitations were sent out to American Society of Emergency Radiology (ASER) and Association of University Radiologists (AUR) members. Responses were collected over a period of 8 days. Descriptive analyses and multivariate modeling were performed using SAS v9.4 software. RESULTS: A total of 689 responses from radiologists across 44 different states met the criteria for inclusion in the analysis. As many as 61% of respondents rated their level of anxiety with regard to COVID-19 to be a 7 out of 10 or greater, and higher scores were positively correlated the standardized number of COVID-19 cases in a respondent's state (RR = 1.11, 95% CI: 1.02-1.21, p = 0.01). Citing the stressor of "personal health" was a strong predictor of higher anxiety scores (RR 1.23; 95% CI: 1.13-1.34, p < 0.01). By contrast, participants who reported needing no coping methods were more likely to self-report lower anxiety scores (RR 0.4; 95% CI: 0.3-0.53, p < 0.01). CONCLUSION: COVID-19 has had a significant impact on radiologists across the nation. As these unique stressors continue to evolve, further attention must be paid to the ways in which we may continue to support radiologists working in drastically altered practice environments and in remote settings.

RESUMO

Since the spread of the coronavirus disease 2019 (COVID-19) was designated as a pandemic by the World Health Organization, health care systems have been forced to adapt rapidly to defer less urgent care during the crisis. The United States (U.S.) has adopted a four-phase approach to decreasing and then resuming non-essential work. Through strong restrictive measures, Phase I slowed the spread of disease, allowing states to safely diagnose, isolate, and treat patients with COVID-19. In support of social distancing measures, non-urgent studies were postponed, and this created a backlog. Now, as states transition to Phase II, restrictions on non-essential activities will ease, and radiology departments must re-establish care while continuing to mitigate the risk of COVID-19 transmission all while accommodating this backlog. In this article, we propose a roadmap that incorporates the current practice guidelines and subject matter consensus statements for the phased reopening of non-urgent and elective radiology services. This roadmap will focus on operationalizing these recommendations for patient care and workforce management. Tiered systems are proposed for the prioritization of elective procedures, with physician-to-physician communication encouraged. Infection control methods, provision of personal protective equipment (PPE), and physical distancing measures are highlighted. Finally, changes in hours of operation, hiring strategies, and remote reading services are discussed for their potential to ease the transition to normal operations.

RESUMO

On March 11, 2020, the World Health Organization declared a coronavirus disease 2019 (COVID-19) pandemic. Health care systems worldwide should be prepared for an unusually high volume of patients in the next few weeks to months. Even the most efficient radiology department will undergo tremendous stress when victims of a mass casualty flood the emergency department and in turn the radiology department. A significant increase is expected in the number of imaging studies ordered for the initial diagnosis and treatment follow-up of cases of COVID-19. Here, we highlight recommendations for developing and implementing a mass casualty incident (MCI) plan for a viral outbreak, such as the current COVID-19 infection. The MCI plan consists of several steps, including preparation, mobilization of resources, imaging chain, adjusting imaging protocols, and education, such as MCI plan simulation and in-service training. Having an MCI plan in place for a viral outbreak will protect patients and staff and ultimately decrease virus transmission. The use of simulations will help identify throughput and logistical issues.

RESUMO

OBJECTIVE. Since the outbreak of the novel coronavirus pulmonary illness coronavirus disease 2019 (COVID-19) in China, more than 79,000 people have contracted the virus worldwide. The virus is rapidly spreading with human-to-human transmission despite imposed precautions. Because similar pulmonary syndromes have been reported from other strains of the coronavirus family, our aim is to review the lessons from imaging studies obtained during severe acute respiratory syndrome (SARS) and Middle East respiratory syndrome (MERS) outbreaks. CONCLUSION. The review of experiences with the MERS and SARS outbreaks will help us better understand the role of the radiologist in combating the outbreak of COVID-19. The known imaging manifestations of the novel coronavirus and the possible unknowns will also be discussed.

RESUMO

The escalation of imaging volumes in the emergency department and intensifying demands for rapid radiology results have increased the demand for emergency radiology. The provision of emergency radiology is essential for nearly all radiology practices, from the smallest to the largest. As our radiology specialty responds to the challenge posed by the triple threat of providing 24-7 coverage, high imaging volumes, and rapid turnaround time, various questions regarding emergency radiology have emerged, including its definition and scope, unique operational demands, quality and safety concerns, impact on physician well-being, and future directions. This article reviews the current challenges confronting the subspecialty of emergency radiology and offers insights into preparing for continued growth.

RESUMO

OBJECTIVE: This study is intended to better understand how academic productivity and career advancement differs between men and women emergency radiologists in academic practices. MATERIALS AND METHODS: Parameters of academic achievement were measured, including number of citations, number of publications, and h-index, while also collecting information on academic and leadership ranking among emergency radiologists in North America. RESULTS: In emergency radiology, there are significantly fewer women than men (22.2% vs 77.8%). Of these women, the greatest proportion of women held the lower academic rank of assistant professor (95.4%). Female assistant professors had a higher h-index than men at the same rank (4 vs 2), but it was not statistically significantly higher. There was no significant difference between gender and academic (p = 0.089) or leadership (p = 0.586) rankings. CONCLUSION: This study provides further evidence that gender disparity persists in emergency radiology, with women achieving less upward academic career mobility than men, despite better academic productivity in the earlier stages of their careers. The academic productivity of emergency radiologists at the rank of assistant professor is significantly higher for women than men.

RESUMO

RATIONALE AND OBJECTIVES: Anecdotal reports have recently surfaced of an increase in the number of US senior diagnostic radiology (DR)-bound residency applicants who did not secure a preliminary year position through the Main Resident Match (the Match) of the National Resident Matching Program (NRMP), so-called "partial matches." This study sought to determine the scope of this phenomenon and address potential causes and solutions. MATERIALS AND METHODS: Publicly available and proprietary data from the National Resident Matching Program were analyzed from 2005-2016 to determine the number of partially matched US senior applicants, selectivity of DR residency training, availability of preliminary year positions, number of unique preliminary year applicants, distribution of preliminary year matches by successfully matched applicants in relevant specialties (DR, anesthesiology, dermatology, neurology, physical medicine and rehabilitation, and radiation oncology), and percentage of categorical training programs participating in the Match. RESULTS: Since 2012, there has been a trend toward an increase in the number of partially matched US senior DR applicants, with a transitory recovery in the 2015 Match. Although possible explanations for this increase are proposed, a definitive etiology remains elusive. Strategies to offset this phenomenon include advising perceived at-risk applicants to apply more broadly to preliminary year positions, creating more categorical training positions, abolishing the preliminary year requirement, and drawing high-caliber medical students to the field. CONCLUSIONS: Although a definitive explanation for a recent increase in partial matches remains elusive, strategies exist for DR applicants, residency programs, and the DR academic community to minimize this risk.

RESUMO

OBJECTIVE: The number of 4th-year medical student applications to the field of diagnostic radiology has decreased from 2009 to 2015. The purpose of this study was to learn how radiology departments are recruiting medical students. MATERIALS AND METHODS: An anonymous online survey hyperlink was distributed to the members of the Society of Chairs of Academic Radiology Departments regarding both innovative and proven recruitment strategies. The results were synthesized with a recently published survey of medical students about factors influencing them to go into radiology. RESULTS: Forty of 126 radiology departments completed the survey. Most felt that radiology exposure and curricula require alteration given recent downward trends in medical student applications. A majority (79%) had changed their outreach to medical students in response to these trends. The responding department chairs felt that interactive learning while on rotation was the most important strategy for recruitment. The presence of a diversity program, dedicated medical school educator, or rotating daily assignment for students did not affect the likelihood of filling residency spots in the main match. CONCLUSION: Many radiology departments are changing their outreach to medical students to improve recruitment. Effective strategies to focus on include early active outreach by involving students in the radiology department, thereby framing radiologists as clinicians.

RESUMO

RATIONALE AND OBJECTIVES: In flipped learning, medical students independently learn facts and concepts outside the classroom, and then participate in interactive classes to learn to apply these facts. Although there are recent calls for medical education reform using flipped learning, little has been published on its effectiveness. Our study compares the effects of flipped learning to traditional didactic instruction on students' academic achievement, task value, and achievement emotions. MATERIALS AND METHODS: At three institutions, we alternated flipped learning with traditional didactic lectures during radiology clerkships, with 175 medical students completing a pretest on general diagnostic imaging knowledge to assess baseline cohort comparability. Following instruction, posttests and survey examinations of task value and achievement emotions were administered. Linear mixed effects analysis was used to examine the relationship between test scores and instruction type. Survey responses were modeled using ordinal category logistic regression. Instructor surveys were also collected. RESULTS: There were no baseline differences in test scores. Mean posttest minus pretest scores were 10.5% higher in the flipped learning group than in the didactic instruction group (P = 0.013). Assessment of task value and achievement emotions showed greater task value, increased enjoyment, and decreased boredom with flipped learning (all P < 0.01). All instructors preferred the flipped learning condition. CONCLUSIONS: Flipped learning was associated with increased academic achievement, greater task value, and more positive achievement emotions when compared to traditional didactic instruction. Further investigation of flipped learning methods in radiology education is needed to determine whether flipped learning improves long-term retention of knowledge, academic success, and patient care.

RESUMO

Patients with pathologic processes of the breast commonly present in the Emergency Department (ED). Familiarity with the imaging and management of the most common entities is essential for the radiologist. Additionally, it is important to understand the limitations of ED imaging and management in the acute setting and to recognize when referrals to a specialty breast center are necessary. The goal of this article is to review the clinical presentations, pathophysiology, imaging, and management of emergency breast cases and common breast pathology seen in the ED.

RESUMO

PURPOSE: The aim of this study was to survey fourth-year medical students, both those choosing and those not choosing diagnostic radiology as their specialty, regarding factors influencing their choice of specialty and their perceptions of radiology. METHODS: A voluntary anonymous online survey hyperlink was sent to 141 US medical schools for distribution to fourth-year students. Topics included demographics, radiology education, specialty choice and influencing factors, and opinions of radiology. RESULTS: A representative sampling (7%) of 2015 fourth-year medical students (n = 1,219; 51% men, 49% women) participated: 7% were applying in radiology and 93% were not. For respondents applying in radiology, the most important factor was intellectual challenge. For respondents applying in nonradiology specialties, degree of patient contact was the most important factor in the decision not to choose radiology; job market was not listed as a top-three factor. Women were less likely than men to apply in radiology (P < .001), with radiology selected by 11.8% of men (56 of 476) and only 2.8% of women (13 of 459). Respondents self-identifying as Asian had a significantly higher (P = .015) likelihood of selecting radiology (19 of 156 [12.2%]) than all other races combined (44 of 723 [6.1%]). Respondents at medical schools with required dedicated medical imaging rotations were more likely to choose radiology as a specialty, but most schools still do not require the clerkship (82%). CONCLUSIONS: The reasons fourth-year medical students choose, or do not choose, diagnostic radiology as a specialty are multifactorial, but noncontrollable factors, such as the job market, proved less compelling than controllable factors, such as taking a radiology rotation.

RESUMO

BACKGROUND: The early and accurate identification of patients with blunt thoracic aortic injury (BTAI) remains a challenge. Traditionally, a portable AP chest X-ray (CXR) is utilized as the initial screening modality for BTAI, however, there is controversy surrounding its sensitivity. The purpose of this study was to assess the sensitivity of CXR as a screening modality for BTAI. METHODS: After IRB approval, all adult (≥18 yo) blunt trauma patients admitted to LAC+USC (01/2011-12/2013) who underwent CXR and chest CT were retrospectively reviewed. Final radiology attending CXR readings were reviewed for mediastinal abnormalities (widened mediastinum, mediastinal to chest width ratio greater than 0.25, irregular aortic arch, blurred aortic contour, opacification of the aortopulmonary window, and apical pleural haematoma) suggestive of aortic injury. Chest CT final attending radiologist readings were utilized as the gold standard for diagnosis of BTAI. The primary outcome analyzed was CXR sensitivity. RESULTS: A total of 3728 patients were included in the study. The majority of patients were male (72.6%); mean age was 43 (SD 20). Median ISS was 9 (IQR 4-17) and median GCS was 15 (IQR 14-15). The most common mechanism of injury was MVC (48.0%), followed by fall (20.6%), and AVP (16.9%). The total number of CXRs demonstrating a mediastinal abnormality was 200 (5.4%). Widened mediastinum was present on 191 (5.1%) of CXRs, blurred aortic contour on 10 (0.3%), and irregular aortic arch on 4 (0.1%). An acute aortic injury confirmed by chest CT was present in 17 (0.5%) patients. Only 7 of these with CT-confirmed BTAI had a mediastinal abnormality identified on CXR, for a sensitivity of 41% (95% CI: 19-67%). CONCLUSION: The results from this study suggest that CXR alone is not a reliable screening modality for BTAI. A combination of screening CXR and careful consideration of other factors, such as mechanism of injury, will be required to effectively discriminate between those who should and should not undergo chest CT.
