Imaging volumes during COVID-19: A Victorian health service experience

BACKGROUNDThe World Health Organisation declared the coronavirus disease 2019 (COVID-19) a pandemic on March 11, 2020. While globally, the relative caseload has been high, Australia’s has been relatively low. During the pandemic, radiology services have seen significant changes in workflow across modalities and a reduction in imaging volumes. AIMTo investigate differences in modality imaging volumes during the COVID-19 pandemic across a large Victorian public health network.METHODSA retrospective analysis from January 2019 to December 2020 compared imaging volumes across two periods corresponding to the pandemic’s first and second waves. Weekly volumes across patient class, modality and mobile imaging were summed for periods: wave 1 (weeks 11 to 16 for 2019; weeks 63 to 68 for 2020) and wave 2 (weeks 28 to 43 for 2019; weeks 80 to 95 for 2020). Microsoft Power Business Intelligence linked to the radiology information system was used to mine all completed examinations.RESULTSSummed weekly data during the pandemic’s first wave showed the greatest decrease of 29.8% in adult outpatient imaging volumes and 46.3% in paediatric emergency department imaging volumes. Adult nuclear medicine demonstrated the greatest decrease of 37.1% for the same period. Paediatric nuclear medicine showed the greatest decrease of 47.8%, with angiography increasing by 50%. The pandemic’s second wave demonstrated the greatest decrease of 23.5% in adult outpatient imaging volumes, with an increase of 18.2% in inpatient imaging volumes. The greatest decrease was 28.5% in paediatric emergency department imaging volumes. Nuclear medicine showed the greatest decrease of 37.1% for the same period. Paediatric nuclear medicine showed the greatest decrease of 36.7%. Mobile imaging utilisation increased between 57.8% and 135.1% during the first and second waves. A strong correlation was observed between mobile and non-mobile imaging in the emergency setting (Spearman’s correlation coefficient = -0.743, P = 0.000). No correlation was observed in the inpatient setting (Spearman’s correlation coefficient = -0.059, P = 0.554).CONCLUSIONNuclear medicine was most impacted, while computed tomography and angiography were the least affected by the pandemic. The impact was less during the pandemic’s second wave. Mobile imaging shows continuous growth during both waves.     

Lessons learned during the COVID-19 pandemic: a single institution radiology chief resident experience

Coronavirus Disease 2019 (COVID-19) has posed incredible new challenges for radiology residency programs, including resident training under tenuous and uncertain conditions, barriers to communication, deployment-induced anxiety, and social isolation. Chief residents and program leadership play a critical role in guiding radiology residents through these unprecedented times. Best practices and creative approaches experienced in a single institution's residency program located in New York City are shared in an effort to encourage other programs struggling with similar obstacles to prioritize resident education and wellness.     

Brief communication: A radiology resident's experience with COVID-19 in New York City

The COVID-19 pandemic impacted New York City severely. As a radiology resident, I was unsure how my role would change as the pandemic unfolded. Like many hospital systems in New York City, my department was asked to assist in the clinical care of patients during the dramatic surge of admissions related to COVID-19. I placed invasive central lines for critically ill patients in the intensive care unit to help reduce the workload on already overwhelmed critical care teams. I also performed direct patient care within dedicated COVID-19 inpatient floors.     

COVID-19: A call for mentorship in radiology

During the COVID-19 pandemic, mentorship relationships have undergone significant strain. Sudden changes in the practice environment have caused radiologists to focus their attention to more immediate and essential clinical needs, thus leaving important extracurricular non-clinical endeavors like mentorship by the wayside. However, mentorship is essential more than ever during the pandemic to build strength and resilience in radiology. Specifically, mentorship can foster job resilience, facilitate career development, promote diversity, support wellness, and stimulate future practice growth during this pandemic. Practical actions are described that mentors can follow to help develop and sustain mentorship relationships during the pandemic.SummaryMentorship is critical now during the COVID-19 pandemic to build strength and resilience in radiology.     

Physical activity,mental health and well-being of adults during initial COVID-19 containment strategies: A multi-country cross-sectional analysis

ObjectivesTo assess physical activity (PA), mental health and well-being of adults in the United Kingdom (UK), Ireland, New Zealand and Australia during the initial stages of National governments’ Coronavirus disease (COVID-19) containment responses.DesignObservational, cross-sectional.MethodsAn online survey was disseminated to adults (n = 8,425; 44.5 ± 14.8y) residing in the UK, Ireland, New Zealand and Australia within the first 2-6 weeks of government-mandated COVID-19 restrictions. Main outcome measures included: Stages of Change scale for exercise behaviour change; International Physical Activity Questionnaire (short-form); World Health Organisation-5 Well-being Index; and the Depression Anxiety and Stress Scale-9.ResultsParticipants who reported a negative change in exercise behaviour from before initial COVID-19 restrictions to during the initial COVID-19 restrictions demonstrated poorer mental health and well-being compared to those demonstrating either a positive-or no change in their exercise behaviour (p < 0.001). Whilst women reported more positive changes in exercise behaviour, young people (18-29y) reported more negative changes (both p < 0.001). Individuals who had more positive exercise behaviours reported better mental health and well-being (p < 0.001). Although there were no differences in PA between countries, individuals in New Zealand reported better mental health and well-being (p < 0.001).ConclusionThe initial COVID-19 restrictions have differentially impacted upon PA habits of individuals based upon their age and sex, and therefore have important implications for international policy and guideline recommendations. Public health interventions that encourage PA should target specific groups (e.g., men, young adults) who are most vulnerable to the negative effects of physical distancing and/or self-isolation.     

Role of interventional radiology in the treatment of COVID-19 patients: Early experience from an epicenter

ObjectiveTo highlight the role of interventional radiology (IR) in the treatment of patients hospitalized with coronavirus disease 2019 (COVID-19).MethodsRetrospective review of hospitalized patients who tested positive for severe acute respiratory syndrome coronavirus 2 (SARS-CoV-2) and had one or more IR procedures at a tertiary referral hospital in New York City during a 6-week period in April and May of 2020.ResultsOf the 724 patients admitted with COVID-19, 92 (12.7%) underwent 124 interventional radiology procedures (79.8% in IR suite, 20.2% at bedside). The median age of IR patients was 63 years (range 24–86 years); 39.1% were female; 35.9% in the intensive care unit. The most commonly performed IR procedures were central venous catheter placement (31.5%), inferior vena cava filter placement (9.7%), angiography/embolization (4.8%), gastrostomy tube placement (9.7%), image-guided biopsy (10.5%), abscess drainage (9.7%), and cholecystostomy tube placement (6.5%). Thoracentesis/chest tube placement and nephrostomy tube placement were also performed as well as catheter-directed thrombolysis of massive pulmonary embolism and thrombectomy of deep vein thrombosis. General anesthesia (10.5%), monitored anesthesia care (18.5%), moderate sedation (29.8%), or local anesthetic (41.1%) was utilized. There were 3 (2.4%) minor complications (SIR adverse event class B), 1 (0.8%) major complication (class C), and no procedure-related death. With a median follow-up of 4.3 months, 1.1% of patients remain hospitalized, 16.3% died, and 82.6% were discharged.ConclusionInterventional radiology participated in the care of hospitalized COVID-19 patients by performing a wide variety of necessary procedures.     

Radiological review of rhinocerebral mucormycosis cases during the COVID-19 Pandemic: A single-center experience

Mucormycosis is caused by the fungi belonging to the order Mucorales and class Zygomycetes. The incidence of mucormycosis has increased with the onset of the severe acute respiratory syndrome coronavirus 2 infections leading to the coronavirus disease 2019 (COVID-19) pandemic. This rise is attributed to the use of immunosuppressive medication to treat COVID-19 infections. Authors have retrospectively collected data of our cases of mucormycosis diagnosed from April 2020 to April 2021 at our institute. A total of 20 patients with rhinocerebral mucormycosis were studied. Most of the study subjects were male patients (90%) and were of the age group 41-50 years. Most patients in the review had comorbidities (85%) with diabetes being the most common comorbidity. Para nasal sinuses were involved in all the cases. Involvement of the neck spaces was present in 60% of the cases. Involvement of the central nervous system was present in 80% of the cases. Orbital involvement was present in 90% of the cases. The authors reviewed the various imaging findings of mucormycosis on computed tomography and magnetic resonance imaging in this article.     

Container CT scanner: a solution for modular emergency radiology department during the COVID-19 pandemic

During the coronavirus disease 2019 (COVID-19) pandemic period, container computed tomography (CT) scanners were developed and used for the first time in China to perform CT examinations for patients with clinically mild to moderate COVID-19 who did not need to be hospitalized for comprehensive treatment, but needed to be isolated in Fangcang shelter hospitals (also known as makeshift hospitals) to receive some supportive treatment. The container CT is a multidetector CT scanner installed within a radiation-protected stand-alone container (a detachable lead shielding room) that is deployed outside the makeshift hospital buildings. The container CT approach provided various medical institutions with the solution not only for rapid CT installation and high adaptability to site environments, but also for significantly minimizing the risk of cross-infection between radiological personnel and patients during CT examination in the pandemic. In this article, we described the typical setup of a container CT and how it worked for chest CT examinations in Wuhan city, the epicenter of COVID-19 outbreak.

Fangcang shelter hospitals, also known as makeshift hospitals, were developed and used for the first time in China to tackle the coronavirus disease 2019 (COVID-19) outbreak by providing medical care and disease monitoring for patients with mild to moderate COVID-19 who were isolated from their families and communities (1). Similarly, stand-alone computed tomography (CT) scanners, known as container CTs, were developed and used for the first time in China to perform CT examinations on patients with clinically mild to moderate COVID-19 who received supportive treatment at makeshift hospitals. These container CTs were first deployed outside makeshift hospital buildings and later also at some regular hospitals as stand-alone CT scanners designated for fever patients and confirmed COVID-19 patients.Chest CT images have been widely used to help with early diagnosis, assess the degree of pulmonary infectious involvement, monitor disease progression, and evaluate treatment effects (2). These CT examinations were originally performed in regular hospital settings with normally installed CT scanners. However, at makeshift hospitals that were converted from civil building facilities such as stadiums, schools, and exhibition halls, no space was available that could meet the shielding and radiation protection standards necessary to install CT scanners. Furthermore, during that critical pandemic period, many hospitals in Wuhan urgently needed to be equipped with more CT scanners to rapidly improve the imaging examination capabilities for patients with fever, suspected patients, and patients with confirmed COVID-19. Unfortunately, these hospitals usually lack readily available sites for rapid CT installations because it normally takes at least a month to build or remodel a CT shielding room even without the complications of the complete lockdown in Wuhan city. To figure out this issue, under tremendous pressure to rapidly install new CT scanners at both regular hospitals and makeshift hospitals, Chinese medical equipment companies worked closely with frontline radiologists and technologists and developed an innovative container CT, which functions as a modular emergency radiology department. To date, more than 140 container CTs have been installed at makeshift hospitals and regular hospitals in China since the COVID-19 outbreak.In this article, we presented a typical in-depth solution for container CT deployment in Wuhan during the COVID-19 outbreak.     

Virtual medical student radiology clerkships during the COVID-19 pandemic: Distancing is not a barrier

BackgroundStress on medical education caused by COVID-19 has prompted medical schools to bar their students from onsite education at hospitals and clinics, limiting their educational experiences. Radiology is uniquely positioned to be a virtual rotation during this health crisis and beyond.PurposeTo implement virtual radiology clerkships and evaluate educational outcomes.MethodsWe developed virtual radiology clerkships using best practices from adult education theory; emphasizing self-directed and interactive learning through recommended reading materials, pre-recorded lectures, video conferencing, web-based learning modules from the ACR, as well as multimodality radiology resources to allow students flexibility in their individual approach to the subject matter.ResultsThe mean performance on standardized exams for our cohorts was 75% (range 50–96%), matching the national average of 75%. Surveys of medical students after the clerkship showed positive subjective feedback on the content and structure of the course.ConclusionsUnderstanding of medical imaging is vital for student doctors to have a better understanding of applied anatomy, patient care strategies, appropriate use, and image interpretation. Radiology is uniquely positioned to be taught in a virtual format, or in a combination of online and in-person activities. Standardized examination performance for our institutional virtual radiology clerkships is comparable to performance on traditional courses. Virtual clerkships designed with adult learners in mind can help student doctors prepare for residency and future independent practice as they build knowledge and skills needed to provide high quality patient care.     

Online learning during the COVID-19 pandemic: Perceptions of allied health sciences undergraduates

IntroductionThe purpose of this study was to determine the perceptions of Allied Health Sciences undergraduates towards online learning during the COVID 19 outbreak.MethodsA cross-sectional study was conducted with undergraduates of the Faculty of Allied Health Sciences, University of Peradeniya, Sri Lanka. A self-administered online questionnaire consisted of four sections to evaluate demographic information; details of online learning; perspectives and challenges on online learning were used for data collection.ResultsA total of 518 responses were received from the five disciplines of radiography (32.8%), nursing (24.9%), medical laboratory sciences (18.2%), pharmacy (14.5%), and physiotherapy (9.7%), resulting in a 76.4% response rate. The majority preferred smartphones (73.2%) for online access, and Zoom is the most utilized online communicating platform (72.8%). The overall respondent's perception score ranged from 9 to 27 (Positive ≥ 18, Neutral = 18, Negative ≤ 18) with a mean (SD) of 20.4 (4.0). Even though the majority (59.7%) agreed that online learning is more comfortable to communicate than conventional learning, most respondents (48.3%) have a negative perception towards offering practical and clinical-based subjects online. Poor internet connections (67.0%) and the lack of electronic devices (53.3%) were the most significant challenges encountered during online learning.ConclusionThe majority of the students have a positive perception towards online learning. Online learning appears to be an efficient learning strategy when students have equal access to online facilities.Implications for practiceAlthough the allied health undergraduates faced several challenges, they demonstrated their versatility and acceptance of the online learning strategy during the COVID-19 pandemic. Therefore a well-structured online learning programme will be beneficial for students to continue their studies during a pandemic.     

Impact of COVID-19 pandemic on radiology education,training, and practice: A narrative review

Radiology education and training is of paramount clinical importance given the prominence of medical imaging utilization in effective clinical practice. The incorporation of basic radiology in the medical curriculum has continued to evolve, focusing on teaching image interpretation skills, the appropriate ordering of radiological investigations, judicious use of ionizing radiation, and providing exposure to interventional radiology. Advancements in radiology have been driven by the digital revolution, which has, in turn, had a positive impact on radiology education and training. Upon the advent of the corona virus disease 2019 (COVID-19) pandemic, many training institutions and hospitals adhered to directives which advised rescheduling of non-urgent outpatient appointments. This inevitably impacted the workflow of the radiology department, which resulted in the reduction of clinical in-person case reviews and consultations, as well as in-person teaching sessions. Several medical schools and research centers completely suspended face-to-face academic activity. This led to challenges for medical teachers to complete the radiology syllabus while ensuring that teaching activities continued safely and effectively. As a result, online teaching platforms have virtually replaced didactic face-to-face lectures. Radiology educators also sought other strategies to incorporate interactive teaching sessions while adopting the e-learning approach, as they were cognizant of the limitations that this may have on students’ clinical expertise. Migration to online methods to review live cases, journal clubs, simulation-based training, clinical interaction, and radiology examination protocolling are a few examples of successfully addressing the limitations in reduced clinical exposure. In this review paper, we discuss (1) The impact of the COVID-19 pandemic on radiology education, training, and practice; (2) Challenges and strategies involved in delivering online radiology education for undergraduates and postgraduates during the COVID-19 pandemic; and (3) Difference between the implementation of radiology education during the COVID-19 pandemic and pre-COVID-19 era.     

Medical student education in the time of COVID-19: A virtual solution to the introductory radiology elective

Rationale and objectivesDuring the COVID-19 pandemic, medical educators and students are facing unprecedented challenges while navigating the new virtual landscape that social-distancing policies mandate. In response to these challenges, a new virtual introduction to radiology elective was established with unique online resources and curriculum.Materials and methodsA previously in-person 2-week introductory radiology elective was converted into a completely virtual experience using an internally developed, open-source, peer-reviewed, web-based teaching modules combined with virtual lectures, interdisciplinary conferences, and readout sessions of de-identified cases loaded to a DICOM viewer. Students from the first four months of course enrollment completed a multiple choice pre- and post-course knowledge assessments and a 5-point Likert Scale survey as part of their educational experience.ResultsIn total, 26 4th-year medical students participated over 4 separate 2-week sessions from July to October of 2020. This included 12 students from the home intuition and 14 visiting students. On average, students scored 62.2% on the 55-question pre-test and 89.0% on the same test upon completion of the course, a statistically significant increase (p < 0.001). All 26 students felt engaged throughout the course. All 26 agreed (23 “strongly agreed”) that they were more comfortable looking at imaging studies following the course. All 26 also agreed (21 “strongly agreed”) that the course helped them prepare for their future clinical rotations and careers.ConclusionInitial pilot program using unique web-based resources and student encounters during a two-week virtual introductory radiology elective proved to be a positive educational experience for the first 26 students enrolled.
