A Comprehensive Health Effects Assessment of the Use of Sanitizers and Disinfectants during COVID-19 Pandemic: A Global Survey (preprint)

COVID-19 has affected all aspects of human life so far. From the outset of the pandemic, preventing the spread of COVID-19 through the observance of health protocols, especially the use of sanitizers and disinfectants was given more attention. Despite the effectiveness of disinfection chemicals in controlling and preventing COVID-19, there are critical concerns about their adverse effects on human health. This study aims to assess the health effects of sanitizers and disinfectants on a global scale. A total of 91056 participants from 154 countries participated in this cross-sectional study through an electronic questionnaire. Results implied that detergents (67%), alcohol-based materials (56%), and chlorinated compounds (32%) were the most commonly used types of sanitizers and disinfectants. Most frequently reported health issues include skin complications 48.8% and respiratory complications 29.8%. The Chi-square test showed a significant association between chlorinated compounds with all possible health complications under investigation (p-value < 0.001). Examination of risk factors based on multivariate regression analysis showed that alcohols-based materials were associated with skin complications (OR, 1.98; 95%CI, 1.87–2.09), per-chlorine was associated with eye complications (OR, 1.83; 95%CI, 1.74–1.93), and highly likely with itching and throat irritation (OR, 2.00; 95%CI, 1.90–2.11). Furthermore, formaldehyde was associated with a higher prevalence of neurological complications (OR, 2.17; 95%CI, 1.92–2.44). The findings of the current study suggest that health authorities need to implement more awareness programs about the side effects of using sanitizers and disinfectants during viral epidemics.

The Perceived Impact of the Covid-19 Pandemic on Medical Student Education and Training – An International Survey (preprint)

Background: The Covid-19 pandemic led to significant changes and disruptions to medical education worldwide. We evaluated medical student perceived views on training, their experiences and changes to teaching methods during the pandemic. Methods: An online survey of medical students was conducted in the Autumn of 2020. An international network of collaborators facilitated participant recruitment. Students were surveyed on their perceived overall impact of Covid-19 on their training and several exposure variables. Univariate analyses and adjusted multivariable analysis were performed to determine strengths in associations. Results: A total of 1604 eligible participants from 45 countries took part in this survey and 56.3% (n=860) of these were female. The median age was 21 (Inter Quartile Range:21-23). Nearly half (49.6%, n=796) of medical students were in their clinical years. The majority (n=1356, 84.5%) were residents of a low or middle income country. A total of 1305 (81.4%) participants reported that the Covid-19 pandemic had an overall negative impact on their training. On adjusted analysis, being 21 or younger, females, those reporting a decline in conventional lectures and ward based teaching were more likely to report an overall negative impact on their training ( p≤ 0.001). However, an increase in clinical responsibilities was associated with lower odds of participants reporting a negative impact on training ( p <0.001). The participant’s resident nation economy and stage of training were associated with some of the participant training experiences surveyed ( p <0.05). Conclusion: Medical students reported an overall significant negative impact of the Covid-19 pandemic on their undergraduate training. The efficacy of novel virtual methods of teaching to supplement traditional teaching methods warrants further research.

The perceived global impact of the COVID-19 pandemic on doctors’ medical and surgical training: an international survey (preprint)

Abstract Introduction The COVID-19 pandemic has resulted in a significant burden on healthcare systems causing disruption to medical and surgical training of doctors globally. Aims and objectives This is the first international survey assessing the perceived impact of the COVID-19 pandemic on training of doctors of all grades and specialties. Methods An online global survey was disseminated using Survey Monkey® between 4th August 2020 and 17th November 2020. A global network of collaborators facilitated participant recruitment. Data was collated anonymously with informed consent and analysed using univariate and adjusted multivariable analysis. Results 743 doctors of median age 27 (IQR: 25-30) were included with the majority (56.8%, n=422) being male. Two-thirds of doctors were in a training post (66.5%, n=494), 52.9% (n=393) in a surgical specialty and 53.0% (n= 394) in low- and middle-income countries. 69.2% (n=514) reported an overall perceived negative impact of the COVID-19 pandemic on their training. A significant decline was noted among non-virtual teaching methods such as face-to-face lectures, tutorials, ward-based teaching, theatre sessions, conferences, simulation sessions and morbidity and mortality meetings (p≤0.05). Doctors from low or middle-income countries were associated with perceived inadequate supervision while performing invasive procedures under general, local or regional anaesthetic. (p≤0.05) Conclusion In addition to the detrimental impact of the COVID-19 pandemic on healthcare infrastructure, there has been an indirect consequence of disrupted training within medical and surgical subspecialties. A focus on reconfiguration of training programs through a variety of additional resources will become imperative to reduce the long-term sequalae of COVID-19 on doctors’ training.
