A Survey of College Students on the Preference for Online Teaching Videos of Variable Durations in Online Flipped Classroom.

In the spring semester of 2020, online flipped classroom was used to replace offline face-to-face teaching of the physiology course at Xiangya School of Medicine. In order to analyze the preferences and utilization of different teaching resources by students, registered questionnaire was applied to investigate the preference divergence of the students on the duration of different teaching videos used in the online flipped classroom model. One hundred forty-seven students of clinical medicine in grade 2018 of Xiangya School of Medicine were selected as the research objects. Three formal surveys were conducted in total. The results showed that there were significant divergences in preference of students for different durations in the first two surveys. 56.43 and 50.00% of the students preferred 15 min mini-video, whereas 43.57 and 50.00% preferred 45 min complete video. Meanwhile, students showed a significant preference for mini-video in active learning before class, with 65.00 and 59.29% watched only mini-video, 17.14 and 25.71% watched only complete videos, and 17.86 and 15.00% watched both mini and complete videos. Although most students preferred to watch mini-video in active learning before class, there was a significant proportion of students who watched complete video before class. The results suggested that the individualization of student in the online flipped classroom is prominent. Multiple logistic regression analysis showed that the selection of videos with different durations at different time points (before, in and after class) was significantly associated with the characteristics of the videos themselves. Therefore, the construction of online teaching resources and the application of teaching methods should consider the requirements of different student groups and provide a variety of online curriculum resources.

Evaluation of a community-based mobile video breastfeeding intervention in Khayelitsha, South Africa: The Philani MOVIE cluster-randomized controlled trial.

BACKGROUND: In South Africa, breastfeeding promotion is a national health priority. Regular perinatal home visits by community health workers (CHWs) have helped promote exclusive breastfeeding (EBF) in underresourced settings. Innovative, digital approaches including mobile video content have also shown promise, especially as access to mobile technology increases among CHWs. We measured the effects of an animated, mobile video series, the Philani MObile Video Intervention for Exclusive breastfeeding (MOVIE), delivered by a cadre of CHWs ("mentor mothers"). METHODS AND FINDINGS: We conducted a stratified, cluster-randomized controlled trial from November 2018 to March 2020 in Khayelitsha, South Africa. The trial was conducted in collaboration with the Philani Maternal Child Health and Nutrition Trust, a nongovernmental community health organization. We quantified the effect of the MOVIE intervention on EBF at 1 and 5 months (primary outcomes), and on other infant feeding practices and maternal knowledge (secondary outcomes). We randomized 1,502 pregnant women in 84 clusters 1:1 to 2 study arms. Participants' median age was 26 years, 36.9% had completed secondary school, and 18.3% were employed. Mentor mothers in the video intervention arm provided standard-of-care counseling plus the MOVIE intervention; mentor mothers in the control arm provided standard of care only. Within the causal impact evaluation, we nested a mixed-methods performance evaluation measuring mentor mothers' time use and eliciting their subjective experiences through in-depth interviews. At both points of follow-up, we observed no statistically significant differences between the video intervention and the control arm with regard to EBF rates and other infant feeding practices [EBF in the last 24 hours at 1 month: RR 0.93 (95% CI 0.86 to 1.01, P = 0.091); EBF in the last 24 hours at 5 months: RR 0.90 (95% CI 0.77 to 1.04, P = 0.152)]. We observed a small, but significant improvement in maternal knowledge at the 1-month follow-up, but not at the 5-month follow-up. The interpretation of the results from this causal impact evaluation changes when we consider the results of the nested mixed-methods performance evaluation. The mean time spent per home visit was similar across study arms, but the intervention group spent approximately 40% of their visit time viewing videos. The absence of difference in effects on primary and secondary endpoints implies that, for the same time investment, the video intervention was as effective as face-to-face counseling with a mentor mother. The videos were also highly valued by mentor mothers and participants. Study limitations include a high loss to follow-up at 5 months after premature termination of the trial due to the COVID-19 pandemic and changes in mentor mother service demarcations. CONCLUSIONS: This trial measured the effect of a video-based, mobile health (mHealth) intervention, delivered by CHWs during home visits in an underresourced setting. The videos replaced about two-fifths of CHWs' direct engagement time with participants in the intervention arm. The similar outcomes in the 2 study arms thus suggest that the videos were as effective as face-to-face counselling, when CHWs used them to replace a portion of that counselling. Where CHWs are scarce, mHealth video interventions could be a feasible and practical solution, supporting the delivery and scaling of community health promotion services. TRIAL REGISTRATION: The study and its outcomes were registered at clinicaltrials.gov (#NCT03688217) on September 27, 2018.

Power of the collective: A review of multimodal internet-based surgical education resources in the 21st century.

Electronic resources have changed surgical education in the 21st century. Resources spanning from digital textbooks to multiple choice question banks, online society meetings, and social media can facilitate surgical education. The COVID pandemic drastically changed the paradigm for education. The ramifications of Zoom lectures and online surgical society meetings will last into the future. Educators and learners can be empowered by the many available electronic resources to enhance surgical training and education.

Task force veterinary anatomy: joint efforts of the five German veterinary schools to ensure education during the COVID-19 pandemic.

At the start of the COVID-pandemic in March 2020, the Institutes of Veterinary Anatomy of the five German educational institutions were confronted with the challenge of digitalising all lectures for the second and fourth semesters of veterinary students. After an online kick-off event and a preliminary status quo meeting, available digital teaching material was exchanged for students to stream from learning platforms. Lectures were either synchronized or made available as audio recordings and connotated slides on the learning platforms. Fortunately, digital microscopic slides had already been in use, which made it easy for students to access them. Dissection exercises mostly consisted of self-study, using instructive videos and interactive exercises. In the second half of the semester, four of the educational institutions were able to offer a restricted number of in-person gross anatomy classes under reinforced conditions. Success monitoring took place online through different formats, and partially on a voluntary basis, via the learning platforms. Although the past two semesters had to almost exclusively take place online due to the unprecedented circumstances, and joint efforts of the five veterinary institutions, there is a general consensus that the practical education in anatomy, histology and embryology is essential to veterinary students. In fact, it is the only way they can obtain the necessary skills to successfully complete the rest of their degree.

Teaching clinical practical and communication skills of the clinical skills lab of the University of Veterinary Medicine Hannover, Foundation, Germany during the COVID-19 pandemic.

Objective: The aim of the project is to teach clinical practical and communication skills in the Clinical Skills Lab (CSL) of the University of Veterinary Medicine Hannover, Foundation (TiHo) during the COVID-19 pandemic. Methodology: As a measure to limit potential SARS-CoV2 infections, the CSL learning stations were digitised and made available on the Moodle learning platform of the TiHo. Online quiz stations were also developed, as well as improvisations that allowed students to practise practical skills at home using everyday materials. Courses for Practical Year (PY) students were digitised and again combined with classroom exercises throughout the year. The teaching formats could be evaluated by the students by means of a questionnaire using a Likert scale (1=agree; 4=disagree). Results: A total of 24.92% of students (n=1272) completed the learning stations with improvisations. The quiz stations were completed with a percentage of 75.08%. Students indicated that the improvisations were easily implementable from home (M=1.33) and assisted in learning the practical skills in question (M=1.89). The quiz stations were considered helpful (M=1.40) and complementary to previous CSL offers (M=1.13). The PY students found the amount of teaching materials adequate (M=1.76) and described communication with the lecturers as problem-free (compulsory electives=1.24). Conclusions: Digital teaching is suitable as a supplement to existing face-to-face courses at the CSL, but cannot replace on-site training under the guidance of trained personnel. The CSL will continue to strive for a combination of online and face-to-face courses for some learning stations in the future.

Purposeful Remote Radiology Education: Strategies and Recommendations.

The COVID-19 global pandemic has presented new challenges to radiology educators and their learners. As a specialty that is accustomed to adapting to continual technologic innovation, as well as one with the capacity for remote work, radiology is uniquely positioned to meet these challenges by taking advantage of online remote educational strategies. This represents an opportunity to not only leverage new methods and technologies but also reexamine the most effective way to implement established ones. The authors review the benefits of taking a purposeful goal-oriented approach to these challenges, provide a corresponding qreview of the general categories of resources that are currently available, and explore educational strategies by using broad categories of software solutions. An invited commentary by Awan is available online. Online supplemental material is available for this article. ©RSNA, 2021.

Pretesting a poster that communicates principles of COVID-19 prevention at educational institutions in Depok City, Indonesia.

The Ministry of Health of the Republic of Indonesia has developed a COVID-19 prevention poster for use in educational institutions. The poster was pretested to determine the reactions of individuals at educational institutions in Depok City in relation to various aspects of communication, such as attraction, comprehension, acceptability, self-involvement and persuasion. The research was descriptive and qualitative, and informants were selected by purposive sampling. The six research informants were teachers and students from a junior high school and a senior high school. Data were collected by using in-depth virtual interviews, and data were analysed using thematic analysis. According to our findings, both teachers and students found the information, images and words of the poster interesting, while the language and terms used were easily understood. In addition, the information was useful and appropriate to the situation and needs. However, titles should be more attractive and specific. In conclusion, according to the input from teachers and students, the COVID-19 prevention poster for educational institutions needs minor revisions. An additional recommendation was that the Indonesian Ministry of Health logo should be added to confirm the source and credibility of the poster.

Advancing Visual Health Communication Research to Improve Infodemic Response.

During public health crises like the ongoing novel coronavirus pandemic, there is a need to amplify and improve critical health communication messages. This need is due to pandemics producing infodemic conditions, meaning the public information environment is oversaturated with information of questionable accuracy and utility. The strategic use of visuals can be leveraged to improve the quality of health communication during public health crises and lessen the unintended effects of infodemic conditions. In this essay, we review previous visual communication theorizing and research that provide insights for effective and efficient use of graphical (e.g., data visualizations) and illustrative (e.g., photos, illustrations, and content features) visuals. We also discuss and advocate for more systematic research on visual misinformation and visual narratives, as there are significant gaps in the literature about how people interpret, act on, and engage with these visual content types. More systematic research about these areas of visual health communication research will improve public communication during future public health crises.

Evaluating the effect of infographics on public recall, sentiment and willingness to use face masks during the COVID-19 pandemic: a randomised internet-based questionnaire study.

BACKGROUND: The use of face masks remains contentious, with international variation in practice. Their prevalence in the UK, is likely to increase due to new legislation. Clear information regarding the appropriate use of masks is needed, to ensure compliance with policies to reduce transmission of COVID-19. We aimed to assess the impact of visual representations of guidance, or infographics, upon the knowledge of appropriate face mask usage in a representative UK cohort. METHODS: Adult patients were recruited to this randomised internet-based questionnaire study during the 12-14 May 2020 from across the UK. Respondents viewed one of five public health stimuli regarding the use of face masks, or no stimulus. The groups accessed aids by the European Centre for Disease Control (EUCDC), World Health Organisation (WHO), Singaporean Ministry of Health (SMOH), text from the UK government (UK Gov), or an infographic designed by the Behavioural Insights Team (BIT). The primary outcome was to evaluate the effect of each infographic upon participants' recall of face mask technique, sentiments and willingness to wear a face covering. Secondary outcomes included the effect of symptomology and socio-demographic factors. RESULTS: 4099 respondents were randomised (1009 control, 628 EUCDC, 526 WHO, 639 SMOH, 661 UKGOV and 606 BIT). Stimuli from the WHO, SMOH and BIT demonstrated significantly higher average recall scores compared to the controls (7.40 v. 7.38 v. 7.34 v. 6.97, P < 0.001). BIT's stimulus led to the highest confidence about mask-wearing (87%). Only 48.2% of the cohort felt stimuli reduced anxiety about COVID-19. However, willingness to use a mask was high, (range 84 to 88%). CONCLUSIONS: To ensure the appropriate use of masks, as mandated by UK law, guidance must provide sufficient information, yet remain understandable. Infographics can aid the recall of correct mask techniques by highlighting salient steps and reducing cognitive burden. They have also demonstrated greater trustworthiness than text-only guidance. The effect of infographics upon COVID-19-related anxiety was poor, and they should be further developed to address this sentiment. A willingness to wear face masks has, however, been demonstrated.

Preparing Infographics for Post-publication Promotion of Research on Social Media.

Infographics are pictorial representations of information intended to disseminate information quickly and clearly. Their use has increased in the past decade due to wider and easy access to technology. Infographics are being increasingly used for public advisories, disseminating protocols for healthcare professionals, and post-publication promotion of research. Due to their potential to rapidly reach a vast audience, these have gained larger importance during the coronavirus disease 2019 pandemic. Two key aspects determine the quality of infographics, content and visual appeal. In this brief, the authors attempt to delineate the key aspects of designing an infographic, and the freeware that they may have at their disposal for creating informative, appealing, and useful infographics.

Distance support and online intervention to blind and visually impaired children during the pandemic COVID-19.

The COVID-19 pandemic imposed dramatic changes to everyone's daily routines, but especially to children with developmental disabilities. The Robert Hollman Foundation decided not to interrupt its service to all the visually impaired children and initiated a Distance Support Project. It was an online process covering all aspects of support for the children and involving audio-video calls, videos and tailored-made multisensory material created specifically for each child. A questionnaire, carried out after the 5-month project duration, was created to collect feedback from parents and professionals to understand the impact this project had on everyone involved. Overall both parents and professionals indicated high levels of satisfaction, but in a significant number of questions parents reported consistently higher levels of satisfaction (p-value <0.001). It was shown that parents felt reassured at this otherwise very difficult time because their children were able to continue their treatment, even if in a very different way. This fact encourages us to consider enriching our existing programmes of support and care, integrating this online approach when necessary. At the same time, it seems clear that the responses of the professionals indicate their belief that the benefits of the traditional ways of working remain of unquestionable importance for children with sight deprivation.

Using comics and curiosity to drive pandemic research on a national scale.

An independent online Public Health survey regarding the COVID-19 pandemic was conducted during an Alert Level 4 lockdown, the highest possible, in New Zealand. An illustrated and curiosity-driven public engagement campaign was designed to advertise survey participation, and performance compared with a standard approach using randomised controlled A/B Split tests. The 'Caretoon' approach featured comic illustrations, appealed to goodwill and was intended to pique curiosity. This linked to an illustrated version of the survey which, upon completion, gave a personalised comic summary showing how respondent's answers compared with national averages. The standard ad and survey were not illustrated with comics, and did not provide a personalised comic summary on completion. Both approaches were cost- and time-effective, together resulting in 18,788 responses over six days. The Caretoon approach outperformed the standard approach in terms of the number of people reached, engaged, survey link clicks, gender and ethnic diversity amongst respondents, and cost-effectiveness of advertising. This came at the expense of a small reduction in the proportion of completed surveys and male respondents. The research evidences objective value of public engagement activity, comics and curiosity as tools which can support Public Health research on a national scale.

Intraoperative aerosol box use: does an educational visual aid reduce contamination?

BACKGROUND: The aerosol box was rapidly developed and disseminated to minimize viral exposure during aerosolizing procedures during the COVID-19 pandemic, yet users may not understand how to use and clean the device. This could potentially lead to increased viral exposure to subsequent patients and practitioners. We evaluated intraoperative contamination and aerosol box decontamination and the impact of a preoperative educational visual aid. METHODS: Using a double-blinded randomized design, forty-four anesthesiology trainees and faculty completed a simulated anesthetic case using an aerosol box contaminated with a fluorescent marker; half of the subjects received a visual aid prior to the simulation. Intraoperative contamination was evaluated at 10 standardized locations using an ultraviolet (UV) light. Next, subjects were instructed to clean the aerosol box for use on the next patient. Following cleaning, the box was evaluated for decontamination using an UV light. RESULTS: Median total contamination score was significantly reduced in the experimental group (5.0 vs. 10.0, P < 0.001). The aerosol box was completely cleaned by 36.4% of subjects in the experimental group compared to 4.5% in the control group (P = 0.009). CONCLUSIONS: The use of a visual aid significantly decreased intraoperative contamination and improved box cleaning. Despite these findings, a potentially clinically significant amount of viral exposure may exist. Thorough evaluation of the risks and benefits of the aerosol box should be completed prior to use. If an aerosol box is used, a visual aid should be considered to remind practitioners how to best use and clean the box.

[Fighting against COVID-19: clinical activities of spanish rehabilitation physicians: A cross-sectional study]. / Luchando contra la COVID-19: labor asistencial de los médicos rehabilitadores españoles. Estudio transversal.

OBJECTIVE: The aim of this study was to analyse both the impact of the pandemic and clinical and teaching organisation in Spanish Physical Medicine and Rehabilitation Departments during the COVID-19 pandemic. METHODS: A survey was conducted of the tutors of rehabilitation departments. The questionnaire contained 31 questions divided into 6 parts about the following: general information on the department, adaptation of rehabilitation departments to the COVID pandemic, clinical work of rehabilitation physicians, the approach to rehabilitation in COVID patients, and the effects of the pandemic on the health and teaching activity of rehabilitation physicians during this period. RESULTS: A total of 54 responses were obtained. Almost half of the departments cancelled face-to-face medical consultations (40%) and 48% of the treatment rooms were turned into COVID beds. In 30 hospitals (55.6%), the physicians worked in COVID units. Most of the rehabilitation departments developed both graphic and audiovisual material with exercises, referral protocols and guidelines for the rehabilitation management and treatment of COVID 19 patients. Half of the departments reported some anxiety symptoms in medical staff. Tutorial work has been cancelled (40.7%) or reduced (35.2%). CONCLUSIONS: The organisation of Spanish rehabilitation departments in response to the COVID pandemic has been very similar throughout the country. The response of these departments to the healthcare crisis has revealed the versatility of rehabilitation physicians.

The scale of COVID-19 graphs affects understanding, attitudes, and policy preferences.

Mass media routinely present data on coronavirus disease 2019 (COVID-19) diffusion with graphs that use either a log scale or a linear scale. We show that the choice of the scale adopted on these graphs has important consequences on how people understand and react to the information conveyed. In particular, we find that when we show the number of COVID-19 related deaths on a logarithmic scale, people have a less accurate understanding of how the pandemic has developed, make less accurate predictions on its evolution, and have different policy preferences than when they are exposed to a linear scale. Consequently, merely changing the scale the data is presented on can alter public policy preferences and the level of worry about the pandemic, despite the fact that people are routinely exposed to COVID-19 related information. Providing the public with information in ways they understand better can help improving the response to COVID-19, thus, mass media and policymakers communicating to the general public should always describe the evolution of the pandemic using a graph on a linear scale, at least as a default option. Our results suggest that framing matters when communicating to the public.
