Abstract --To understand the utilization of e-learning in disaster medicine, we surveyed the situation of utilization of e-learning and traditional education in disaster medicine in recent half year. Taiwan Society of Disaster Medicine has implemented e-learning program including continuing medical education (CME) into its official website in Jan 2004. We prospectively studied the numbers of members and non-members attending web-based and traditional training programs since then. Because of advances in e-learning, generalization of disaster medicine education should take various modes of e-learning as the method. A new on-line video teaching program has been implemented in June 2005. The study period A was from July 1 2004 to October 31 2004, and the study period B was from July 1 2005 to October 31 2005. During the study period A, there were totally 112 participants attending 144 times of training courses whereas there were 136 participants attending 172 times of training courses during the study period B. At phase A, 84 (75%) of the participants attended traditional DMAT training and 28 (25%) take part in web-based learning. Of 144 individual courses, 115 (80%) belonged to traditional learning and 29 (20%) were e-learning. At phase B, there were 80 students attending e-learning that was significantly higher than the ratio at phase A (50% vs. 25%, P<0.05). In addition, there were 88 individual courses belonging to e-learning that was also significantly higher than the ratio at phase A (51% vs. 20%, P<0.01). Student satisfaction has also significantly been improved after the video-assisted e-learning has been implemented (satisfaction scores 22+4 points vs. 15+5 points, P<0.01). In conclusion, this report demonstrated that the e-learning of disaster medicine has significantly increased web-based learning and CME certification by both members and non-members. Consistent improvement of quality in e-learning should be the priority in the future.
