A cross sectional survey on the effect of COVID-19 related restrictions on undergraduate and postgraduate medical education in Qatar.

BACKGROUND: COVID-19 pandemic has affected all dimensions of day to day life across the world and medical education was no exception. With this study, we aimed to understand the effect of nationwide restrictions on medical education in Qatar, the models of education adopted during this period and perceptions of participants to the same. METHODS: We conducted a cross-sectional study utilizing an online questionnaire distributed via convenience sampling between April-October 2020. Study participants were faculty and trainees in governmental undergraduate and postgraduate medical education institutes. Two sets of questionnaires were designed for each group. They were asked a series of questions to assess pre- and post-COVID pandemic educational practices, their preferred teaching methods, and their familiarity with electronic teaching platforms. Faculty respondents were asked about their perceived barriers to delivery of medical education during the pandemic and their agreement on a 5-point Likert scale on specific elements. Trainees were asked a series of multiple-choice questions to characterize their pre- and post-COVID pandemic educational experiences. Both groups were asked open-ended questions to provide qualitative insights into their answers. Data were analysed using STATA software version 12.0. RESULTS: Majority of trainees (58.5%) responded that the pandemic has adversely affected medical education at both the undergraduate and postgraduate levels. Trainees (58.5%) and faculty (35.7%) reported an increased reliance on e-learning. Trainees preferred face-to-face education, while faculty preferred a combination of models of education delivery (33.5% versus 37.1%, p = 0.38). Although 52.5% of the faculty had no previous experience of delivering education through e-learning modalities, 58.9% however felt confident in using e-learning software. CONCLUSIONS: Faculty and trainees agree that the COVID-19 pandemic has had a significant impact on the provision of medical education and training in Qatar, with an increased dependence on e-learning. As trainee's prefer face-to-face models of education, we may have to consider restructuring of medical curricula in order to ensure that optimum learning is achieved via e-learning, while at the same time enhancing our use, knowledge and understanding of the e -learning methods. Further research is warranted to assess if these changes have influenced objective educational outcomes like graduation rates or board scores.

Clinical characteristics and risk factors for the isolation of multi-drug-resistant Gram-negative bacteria from critically ill patients with COVID-19.

BACKGROUND: We investigated the clinical characteristics and risk factors for the isolation of multi-drug-resistant (MDR) Gram-negative bacteria (GNB) from critically ill COVID-19 patients. METHODS: We retrospectively matched (1:2) critical COVID-19 patients with one or more MDR GNB from any clinical specimen (cases), with those with no MDR GNB isolates (controls). RESULTS: Seventy-eight cases were identified (4.5 per 1000 intensive care unit (ICU) days, 95% confidence interval (CI) 3.6-5.7). Of 98 MDR GNB isolates, the most frequent species were Stenotrophomonas maltophilia (24, 24.5%), and Klebsiella pneumoniae (23, 23.5%). Two (8.7%) K. pneumoniae, and six (85.7%) Pseudomonas aeruginosa isolates were carbapenem resistant. A total of 24 (24.5%) isolates were not considered to be associated with active infection. Those with active infection received appropriate antimicrobial agents within a median of one day. The case group had significantly longer median central venous line days, mechanical ventilation days, and hospital length of stay (P<0.001 for each). All-cause mortality at 28 days was not significantly different between the two groups (P=0.19). Mechanical ventilation days (adjusted odds ratio 1.062, 95% CI 1.012-1.114; P=0.015), but not receipt of corticosteroids or tocilizumab, was independently associated with the isolation of MDR GNB. There was no association between MDR GNB and 28-day all-cause mortality (adjusted odds ratio 2.426, 95% CI 0.833-7.069; P= 0.104). CONCLUSION: In critically ill COVID-19 patients, prevention of MDR GNB colonization and infections requires minimizing the use of invasive devices, and to remove them as soon as their presence is no longer necessary.
