We aimed to explore medical students' online learning patterns and needs by analyzing data obtained from an e-learning portal of Korean medical schools.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.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.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.
