Objective: While pharmacies focus on interpersonal work, patients need to process a lot of information. Therefore, it is important for the pharmacy to provide information according to the situation. This study was conducted for the purpose of providing a video and paper media, and clarifying that it is useful to provide information in various mediums about the method of administering the powdered medicine, which requires an understanding of the operation.Method: Conducted a survey for those who brought prescriptions for infants from March 2016 to about a year and a half. We compared and verified the understanding of the medication method for infants between the paper medium group and the moving image medium group.Results: Differences in the background between the two media use groups were clarified, and path analysis confirmed differences in the factors that affect the reliable administration of each medium to infants. It was revealed that the evaluation of moving image media was higher than the comparison between the groups in terms of usability. Although there was no difference in the ability to use the medium at his own pace, the moving images were significantly higher in understanding the motion.Discussion: There is a limit to the understanding of motions with a single explanation at the pharmacy counter. It was confirmed in this study that information provision using a medium that can be used depending on the situation of the patient is useful as a complementary role in medication instruction. Providing information while appropriately combining information provision in various media is thought to reduce the burden on patients and contribute to improved adherence.
