We aimed to explore medical students' online learning patterns and needs by analyzing data obtained from an e-learning portal of Korean medical schools. Methods: Data were obtained from learning resources and registered users of the e-learning portal by the consortium of 36 Korean medical schools, e-MedEdu (www.mededu.or.kr) over a period of 10 years. Data analytics were performed of its contents and usage patterns using descriptive statistics. Results: The website currently has over 1,600 resources, which have almost tripled over the past decade, and 28,000 registered users. Two hundred and twenty medical faculty have contributed the resources; a majority of them were clinical cases and video clips, which accounted for 30% and 27% of all resources, respectively. The website has received increasing hits over the past decade; annual website hits increased from 80,000 in 2009 to over 300,000 in 2018. The number of hits on resources varied across resource types and subjects; 90% of all website hits were on online videos, and 28% of them originated from mobile devices. Among the online videos, those on procedural skills received more hits than those on patient encounters and video lectures. Conclusion: Our findings demonstrate the increasing use of e-learning in medical education in Korea over the past decade. Our study also shows a wide disparity in the frequency of use in learning resources across resource types and subjects, which have implications for improvements in the design and development of learning resources to better meet medical students' curricular needs and their learning styles.
IntroductionVarious methods and devices have been described for cooling after cardiac arrest, but the ideal cooling method remains unclear. The aim of this study was to compare the neurological outcomes, efficacies and adverse events of surface and endovascular cooling techniques in cardiac arrest patients.MethodsWe performed a multicenter, retrospective, registry-based study of adult cardiac arrest patients treated with therapeutic hypothermia presenting to 24 hospitals across South Korea from 2007 to 2012. We included patients who received therapeutic hypothermia using overall surface or endovascular cooling devices and compared the neurological outcomes, efficacies and adverse events of both cooling techniques. To adjust for differences in the baseline characteristics of each cooling method, we performed one-to-one matching by the propensity score.ResultsIn total, 803 patients were included in the analysis. Of these patients, 559 underwent surface cooling, and the remaining 244 patients underwent endovascular cooling. In the unmatched cohort, a greater number of adverse events occurred in the surface cooling group. Surface cooling was significantly associated with a poor neurological outcome (cerebral performance category 3–5) at hospital discharge (p = 0.01). After propensity score matching, surface cooling was not associated with poor neurological outcome and hospital mortality [odds ratio (OR): 1.26, 95% confidence interval (CI): 0.81-1.96, p = 0.31 and OR: 0.85, 95% CI: 0.55-1.30, p = 0.44, respectively]. Although surface cooling was associated with an increased incidence of adverse events (such as overcooling, rebound hyperthermia, rewarming related hypoglycemia and hypotension) compared with endovascular cooling, these complications were not associated with surface cooling using hydrogel pads.ConclusionsIn the overall matched cohort, no significant difference in neurological outcomes and hospital morality was observed between the surface and endovascular cooling methods.Electronic supplementary materialThe online version of this article (doi:10.1186/s13054-015-0819-7) contains supplementary material, which is available to authorized users.
Background: e-Learning resources have become increasingly popular in medical education; however, there has been scant research on faculty perceptions and use of these resources.Objective: To investigate medical faculty’s use of e-learning resources and to draw on practical implications for fostering their use of such resources.Design: Approximately 500 full-time faculty members in 35 medical schools across the nation in South Korea were invited to participate in a 30-item questionnaire on their perceptions and use of e-learning resources in medical education. The questionnaires were distributed in both online and paper formats. Descriptive analysis and reliability analysis were conducted of the data.Results: Eighty faculty members from 28 medical schools returned the questionnaires. Twenty-two percent of respondents were female and 78% were male, and their rank, disciplines, and years of teaching experience all varied. Participants had positive perceptions of e-learning resources in terms of usefulness for student learning and usability; still, only 39% of them incorporated those resources in their teaching. The most frequently selected reasons for not using e-learning resources in their teaching were ‘lack of resources relevant to my lectures,’ ‘lack of time to use them during lectures,’ and ‘was not aware of their availability.’Conclusions: Our study indicates a gap between medical faculty’s positive perceptions of e-learning resources and their low use of such resources. Our findings highlight the needs for further study of individual and institutional barriers to faculty adoption of e-learning resources to bridge this gap.
Sudden cardiac death (SCD) is a significant issue affecting national health policies. The National Emergency Department Information System for Cardiac Arrest (NEDIS-CA) consortium managed a prospective registry of out-of-hospital cardiac arrest (OHCA) at the emergency department (ED) level. We analyzed the NEDIS-CA data from 29 participating hospitals from January 2008 to July 2009. The primary outcomes were incidence of OHCA and final survival outcomes at discharge. Factors influencing survival outcomes were assessed as secondary outcomes. The implementation of advanced emergency management (drugs, endotracheal intubation) and post-cardiac arrest care (therapeutic hypothermia, coronary intervention) was also investigated. A total of 4,156 resuscitation-attempted OHCAs were included, of which 401 (9.6%) patients survived to discharge and 79 (1.9%) were discharged with good neurologic outcomes. During the study period, there were 1,662,470 ED visits in participant hospitals; therefore, the estimated number of resuscitation-attempted CAs was 1 per 400 ED visits (0.25%). Factors improving survival outcomes included younger age, witnessed collapse, onset in a public place, a shockable rhythm in the pre-hospital setting, and applied advanced resuscitation care. We found that active advanced multidisciplinary resuscitation efforts influenced improvement in the survival rate. Resuscitation by public witnesses improved the short-term outcomes (return of spontaneous circulation, survival admission) but did not increase the survival to discharge rate. Strategies are required to reinforce the chain of survival and high-quality cardiopulmonary resuscitation in Korea.Graphical Abstract
A relatively high rate of KAV (29.7%) was observed, and the time to resumption of a normal diet after ketamine sedation was rather long. It turned out that, however, the adjunctive administration of ondansetron did not effectively reduce the incidence of KAV.
In this study, a high rate (28.4%) of KAV was observed, consistent with prior reports using the intramuscular (IM) route. However, the authors were unable to reduce KAV using adjunctive atropine or metoclopramide. Parents or caregivers should be given more detailed discharge instructions about vomiting and diet considering the relatively long time to resuming a normal diet after ketamine sedation and the fact that KAV often occurred after ED discharge.
