Post COVID-19 trends in simulation use within diagnostic radiography and radiation therapy education

PURPOSE Simulation is used within medical radiation science training. Recent global events and simulation resource uptake has led to significant changes. The aim of this study was to capture post COVID-19 trends and activity of simulation-based education (SBE) in diagnostic radiography and radiation therapy. METHODS An online survey was designed to investigate the role of simulation within diagnostic radiography and radiation therapy education. Survey design was based on literature and experience within the research team. Questions were based around access and use of simulation, future trends and the effects of COVID-19. Participants were diagnostic radiography and/or radiation therapy educators. Data captured in this study was undertaken in March 2022 and compared with previous data from Bridge and colleagues (2021). RESULTS Sixty-seven responses were received across five continents (two from North/South America), Europe was the most widely represented (n=58, 87%). Fifty-three (79%) of participants reported that they use simulation as part of their teaching and learning. Twenty-seven (51%) respondents reported that they had increased their use of simulation because of COVID-19. Sixteen (30%) respondents stated that they were now able to enrol more students because of the pandemic. Fixed models and immersive environments were the two most common simulation activities. Participants reported, to different degrees, that simulation was used across all parts of the curriculum. CONCLUSIONS Simulation is deeply embedded into diagnostic radiography and radiation therapy education. Evidence suggests that the growth of simulation may be slowing. Opportunities exist for the development of guidance, training and best practice resources around simulation. IMPLICATIONS FOR PRACTICE Simulation is a key pedagogical approach for diagnostic radiography and radiation therapy education. Key stakeholders now need to work collaboratively to define standards and best practices.

Informational value of visual nudges during crises: Improving public health outcomes through social media engagement amid COVID-19

In this study, we conceptualize and empirically evaluate how large-scale organizations can utilize the informational value of visual nudges on social media to promote safety among users and thus improve public health outcomes in the context of the coronovirus desease caused by the SARS-CoV-2 virus (COVID-19) pandemic. We construct a unique panel dataset combining data collected from multiple public and proprietary sources. To operationalize visual nudges from user-generated content, we engage in extensive manual classification of images collected from Instagram (IG), Twitter (TW), and Facebook (FB). To examine the relationship between visual nudging and COVID-19 positivity, we rely on a combination of econometric and epidemiological models. We find that when institutional actors share more images containing mask-related information on IG, their COVID-19 positivity rates decrease by up to 25%, on average. Also, given the fragmentary evidence behind FB and TW effects, our results provide suggestive evidence of the "boundary condition” of the visual nudge effect. Finally, empirical evidence indicates the dynamic and curvilinear effect of visual nudges on positivity over time, such that the informational value of visual nudging is most prominent if communicated 3 to 5 weeks ahead of time, on average. Our results demonstrate the informational value of visual nudges communicated through pertinent social media channels, as well as their capacity to improve public health outcomes. This suggests the feasibility of institutional actors using social media engagement to promote safe behaviors. We conclude by discussing how our findings may be used to develop more effective communication strategies regarding public perceptions of mask use and other relevant safety measures. © 2023 The Authors.

The gendered impact of the COVID-19 pandemic on academics working in medical imaging and radiation therapy.

INTRODUCTION: Healthcare workers have been particularly impacted by the COVID-19 pandemic, as have those educating them, albeit differently. Several papers have identified a gendered difference in the impact of the pandemic. This study aims to determine impact of COVID-19 on the health and wellbeing of Medical Imaging and Radiation Therapy (MIRT) academics. METHODS: An electronic survey was designed in English on Qualtrics and distributed via email and online platforms to MIRT academics. Fifty-one questions were used; demographic (n = 9), work patterns (n = 11), general health (n = 8), mental health (n = 2), physical health (n = 10), and workload (n = 11). Overall, 46 were quantitative and five were qualitative 'open-ended' questions. The survey was open between 3rd March 2021 to 1st May 2021. Quantitative analysis was carried out using MS Excel v 16.61.1ss and SPSS v26. RESULTS: The survey reached 32 countries globally and 412 participants; 23.5% identified as men (n = 97) and 76.5% as women (n = 315). Women reported worse sleep quality than men and overwhelmingly felt they would not like to work remotely again if given a choice. A higher percentage of males, 73% versus 40.5% of females reported getting outdoors less. The CORE-10 validated questionnaire found that 10.3% of males (n = 42) and 2.7% of females (n = 11) experienced severe psychological distress the week immediately before the survey was conducted. CONCLUSION: While the study has identified some gender-related differences in the impact of COVID-19 on the mental and physical health of MIRT academics, both males and females have experienced significant deterioration in health and wellbeing due to the pandemic. IMPLICATION FOR PRACTICE: Developing mental health support for MIRT academics and defining optimum methods for raising awareness is recommended.

Control Of Epidemic Spreads Via Testing And Lock-Down

Testing and lock-down are interventions that can combat the spread of an infectious disease. Testing is a targeted instrument that permits the isolation of infectious individuals. Lock-down, on the other hand, is blunt and restricts the mobility of all people. In this paper, we present a compartmental epidemic model that accounts for the impact of lock-down and different kinds of testing, motivated by the nature of the ongoing COVID-19 outbreak. We consider the testing of symptomatic, contact traced, and randomly chosen asymptomatic individuals. Using the model, we first characterize static mobility levels and testing requirements that can dampen the spread asymptotically. We then characterize a threshold-type optimal lock-down policy that minimizes the social impact of an epidemic, modeled via a sum of infection and lockdown costs. Our results are contextualized with realistic parameter values for COVID-19.

International perspectives on radiography practice education.

INTRODUCTION: The radiography profession is built upon strong educational foundations which help ensure graduate radiographers have the required knowledge, skills, and competence to practise safely and effectively. Changing clinical practices, service needs, technological developments, regulatory changes, together with our growing professional evidence-base, all contribute to the need for our curricula to responsive and continually reviewed and enhanced. This study aims to explore similarities and differences in training curricula and follows a 2012 global survey on radiography education and more recent surveys undertaken by the European Federation of Radiographer Societies (EFRS). METHODS: An online questionnaire, based on previous EFRS education and clinical education surveys, which comprised of open and closed questions and consisted of sections designed to ascertain data on: type, level and duration of education programmes leading to an initial or pre-registration qualification in radiography/medical radiation practice, pre-clinical skill development and clinical placement within programmes. The survey was distributed via social media channels and through an international network of professional societies. Descriptive statistics are reported for most analyses while open questions were analysed thematically. RESULTS: Responses were received from 79 individuals from 28 identified countries across four continents. This represented a total of 121 different pre-registration/entry level programmes offered across these institutions. While dedicated diagnostic radiography programmes were most common (42/121), almost one-third of programmes (40/121) offered two or more areas of specialisation within the curriculum. The average of total hours for clinical placement were 1397 h for diagnostic radiography programmes; 1300 h for radiation therapy programmes; 1025 h for nuclear medicine programmes; and 1134 h for combined specialisation programmes, respectively. Institutions provided a range of physical and virtual systems to support pre-clinical skills development. CONCLUSION: Around the world, radiography programmes vary considerably in terms of their level, duration, programme type, pre-clinical and clinical training, use of simulation, and also in terms of class sizes, student/staff ratios, and graduate employment prospects. The ability of graduates to work independently in areas covered within their programmes varied considerably. While some changes around simulation use were evident, given the impact of COVID-19 it would be beneficial for future research to investigate if pre-clinical and clinical education hours or use of simulation resources has changed due to the pandemic. IMPLICATIONS FOR PRACTICE: The heterogeneity that exists between radiography programmes presents a significant challenge in terms of the mutual recognition of qualifications and the international movement of the radiographer workforce.

Modifications to mobile chest radiography technique during the COVID-19 pandemic - implications of X-raying through side room windows.

INTRODUCTION: Modifications to common radiographic techniques have resulted from the challenges presented by the COVID-19 pandemic. Reports exist regarding the potential benefits of undertaking mobile radiography through side room windows. The aim of this study was to evaluate the impact on image quality and exposure factors when undertaking such examinations. METHODS: A phantom based study was undertaken using a digital X-ray room. Control acquisitions, using a commercially available image quality test tool, were performed using standard mobile chest radiography acquisition factors. Image quality (physical and visual), incidence surface air kerma (ISAK), Exposure Index (EI) and Deviation Index (DI) were recorded. Image quality and radiation dose were further assessed for two additional (experimental) scenarios, where a side room window was located immediately adjacent to the exit port of the light beam diaphragm. The goal of experimental scenario one was to modify exposure factors to maintain the control ISAK. The goal of experimental scenario two was to modify exposure factors to maintain the control EI and DI. Dose and image quality data were compared between the three scenarios. RESULTS: To maintain the pre-window (control) ISAK (76 µGy), tube output needed a three-fold increase (90 kV/4 mAs versus 90 kV/11.25 mAs). To maintain EI/DI a more modest increase in tube output was required (90 kV/8 mAs/ISAK 54 µGy). Physical and visual assessments of spatial resolution and signal-to-noise ratio were indifferent between the three scenarios. There was a slight statistically significant reduction in contrast-to-noise ratio when imaging through the glass window (2.3 versus 1.4 and 1.2; P = 0.005). CONCLUSION: Undertaking mobile X-ray examinations through side room windows is potentially feasible but does require an increase in tube output and is likely to be limited by minor reductions in image quality. IMPLICATIONS FOR PRACTICE: Mobile examinations performed through side room windows should only be used in limited circumstances and future clinical evaluation of this technique is warranted.
