Introduction: Medical ethics education is necessary and is becoming more popular in academic settings. This study surveyed medical staff satisfaction and learning outcomes related to medical ethics education on disclosure using a multimedia case teaching video. Method: This study used a survey methodology with pre and post-tests. Participants (n = 730) viewed a multimedia case teaching video designed to teach medical ethics. The video on disclosure was associated with anonymous, self-administered paired-tests on the branches of Taipei City Hospital at Zhongxiao, Renai and Heping Fuyou. To assess learning outcomes, a pre-test was performed before viewing the video and a post-test was performed after viewing. The satisfaction survey was conducted on the Heping Fuyou branch. Results: A total of 730 staff participated in the paired tests, with 633 (86.3%) completing both tests. Total scores increased by 30.6% from the pre-test to the post-test. The number of correct answers increased by 4.4%. There were 224 satisfaction questionnaires completed. More than 80% of the respondents indicated they were satisfied with the overall course, content and teacher's performance. Additionally, 75.9% thought that this course was very helpful and 76.6% would recommend to their peers to participate in future courses. Conclusion: This study suggests that using a multimedia case teaching video is a valuable method for medical ethics education. Participants were highly satisfied and the effect of learning increased. This teaching method for medical ethics education should be considered in developing medical ethics curricula for post-graduate practitioners.
