The study employed online survey techniques. Altogether, 710 questionnaires (Google forms) were developed, and operationalized. The main respondents included 566 medical students, and 143 medical staff from Mbarara University of Science and Technology (MUST), and Kampala International University (KIU), accordingly. Using SPSS, the main statistical analysis tools employed include frequency distribution summary, and Chi-square (x<sup>2</sup>) test. According to the frequency distribution summary, 27% to 42% of the respondents within categorical divides acknowledged occurrence of medical information breaches due to SM usage. Notably, higher levels of the breaches were reported among male students (64%), age-group 18 to 35 years (68%), and WhatsApp users (63%). On the other hand, Chi-square results showed significant levels (p p > 0.05) between medical institutions and medical information breaches. Overall, the vulnerable areas of the breaches identified would serve as important reference points in the process of rationalizing SM usage in medical institutions. Nevertheless, further studies could focus on identification of the key SM usage factors associated with medical information breaches in medical institutions in Uganda.展开更多

Objective: To investigate the continuing education status and demand of nurses in the grass-root medical institutions and thus provide a reference for optimizing the continuing education plan. Methods: From October 2018 to May 2019, a survey of 270 nurses from 28 grass-root medical institutions in Tongliang District of Chongqing was performed using a self-designed questionnaire. Results: In the grass-root medical institutions, the major continuing education pattern of nurses was hospital training and distance education;the continuing education focused on new basic theoretical knowledge and new nursing techniques, and its satisfaction was 67.8%. About 20.6% questionnaire answerers never had received continuing nursing education. As shown by one-way analysis of variance (ANOVA) and binary logistic regression analysis, the following factors were associated with the continuing education participation in the past three years: work unit, organizational affiliation, age, professional title and hospital policies. There were 93.0% questionnaire answerers reflecting that it was necessary to participate in the continuing education and wishing the conformance between the pattern and contents of continuing nursing education and the actual implementation status. Conclusion: The continuing education demand of nurses in the grass-root medical institutions is basic but diverse, and the organizations shall provide effective policy support for continuing education and make the diversified training plan by combining Internet technology, so as to realize the maximization of continuing education participation and keep improving the overall service quality of gross-root nurses.展开更多

However, the theoretical-practical curricula of traditional medical school course still unsatisfactorily contemplate pain management, as well as the palliative care approach. Objective: To assess the knowledge of medical students about pain and palliative care, as well as to identify their perception of teaching these topics during hospitalization. Methods: A cross-sectional observational study, with a descriptive and exploratory approach, data collection for which was carried out between August and November 2020. The target population was medical students, who responded to an online survey of a quantitative, anonymous and follow-up nature. The survey study variables concerned knowledge about pain management and palliative care. Results: An expressive majority of academics showed difficulty in understanding the pathophysiology of pain related to prescribing drugs for pain management purposes, and all of them believe that it is necessary to acquire more knowledge about pain treatment. In parallel, only 9.3% report having received sufficient information regarding palliative care during medical school. Conclusion: The results suggest a certain lack of knowledge and insecurity among medical school students with respect to pain management and care for patients receiving palliative care. The didactical approach to this theme is still deficient in the medical curriculum and requires immediate improvement and new proposals that address the training of these professionals in a more specific and effective way.展开更多
