The dawn of Japan’s super-aged society is accompanied by various problems, including increased social security expenditures and greater nursing care burden as well as reduced labor force. Targeting 2025, when Japan’s baby-boomer generation will be aged ≥75 years, the government’s Ministry of Health, Labour and Welfare is promoting the establishment of local comprehensive support and service provision systems (Comprehensive Community Care Systems). Although such comprehensive community care systems will require medical professionals to provide treatment through collaborative interprofessional cooperation with colleagues in other fields, effective cooperation has currently not been established because of a lack of understanding regarding the roles and functions of other occupations. Considering that the promotion of interprofessional-based collaborative learning prior to university graduation will be important for resolving this problem, we organized a workshop for medical students based in Ehime Prefecture and evaluated its usefulness based on questionnaire surveys administered before and after the workshop. Consequently, it was ascertained that pharmacy, medical, and nursing students had a heightened awareness of “the importance of interprofessional collaboration” after the workshop as against before the workshop. Students’ degree of comprehension of the nature of the work in each category increased significantly. These results demonstrate the importance and effectiveness of students familiarizing themselves with the learning and work content of other fields by working with colleagues in different medical fields as observed in this workshop. They also expect that student-led study groups will contribute to promote the comprehensive community care systems.
