The purpose of this study was to clarify the differences in the self-evaluation of the training depending on the presence or absence of an exercise using simulation teaching materials in the training on the secondary use of nursing information. The training was conducted targeting nurses working in hospitals, and the level of understanding of the training content before and after the training was investigated. According to the results, no significant differences were observed. However, regarding items related to the secondary use of data stored in electronic medical charts, differences in the self-evaluation were recognized in trainees who did an exercise using simulation teaching materials.
