Background: Medicine education in Japan was introduced to junior high schools in 2012. However, the effectiveness of existing education programs is limited. In order to develop more effective programs for high school students, the present study investigated the variables that directly influence medicine use behavior and the magnitude of their influence, using a Bayesian network analysis. Methods: A national cross-sectional survey was conducted in 2017. Eighty-three public high schools across Japan were randomly selected, and questionnaires were administered to 15–16 years old 10th grade students. The number of valid responses was 17,437 (effective response rate was 98.46%). Responses were analyzed to measure students’ behavior toward, attitudes regarding, and knowledge of medicines, and awareness of their prior medicine education. Results: Students’ “attitude score” and “awareness of a class” directly influenced their “behavior score.” The “score on attitude,” which had a large influence on “score on behavior,” was directly influenced by “score on knowledge of proper use” and “awareness of class.” Conclusion: The present study argues that acquiring knowledge of appropriate medicine use leads to the acquisition of favorable attitudes, which may result in behavioral change. Therefore, for medicine education, it is expected that incorporating content related to knowledge acquisition for changing attitudes will be important for promoting behavioral change.

In Japan, within the background of a progressively aging society, a community general support system is gradually being established. Under this system, community pharmacists are expected to expand their activities in local communities. Here, we surveyed the distribution of community pharmacists in Japan by using government statistics. We found that there are 153 towns/villages without community pharmacists, which is about six times the number of towns without physicians (26 towns/villages). The number of community pharmacists per 100000 population was correlated with the population of the municipality. There was a significant difference in the number of community pharmacists per 100000 population between depopulated and non-depopulated areas. A multiple regression analysis revealed that population, financial capability index, and number of physicians per 100000 population were positively associated with the number of community pharmacists per 100000 population in a given municipality. We hope that the survey provides useful information about future issues facing community pharmacy in a community general support system.

BackgroundIn recent years, the popularity of LED lighting has rapidly increased, owing to its many advantages, including economic benefits. We examined the change in the quality of drugs during storage under LED and fluorescent lighting and found that some medicines exhibited a different degree of color change depending on the light source. The purpose of this study was to investigate the effects of different plastic storage bags on the color change over time when various medicines were stored under LED and fluorescent lighting conditions.MethodsPhotostability tests were conducted on several types of target drugs. Subsequently, subjective evaluation by ten evaluators and objective evaluation by image analysis software were carried out regarding color change.ResultsA similar change in color tone was observed after all types of illumination. Subjective evaluation by 10 evaluators revealed that “change in color tone” occurred in the order of bulb-color LED lighting < daylight-color LED lighting < fluorescent lighting, regardless of the type of plastic bags. A similar tendency was observed also in objective evaluation. In this study, it was considered that a brown light-shielding plastic bag was more effective than a normal plastic bag for the prevention of the color change of medicines stored under LED lighting.ConclusionsThe above results suggested that the most appropriate combination of plastic bag and light source for medicine storage was a brown light-shielding plastic bag and bulb-color LED lighting.Electronic supplementary materialThe online version of this article (10.1186/s40780-018-0108-0) contains supplementary material, which is available to authorized users.
