In 2010, WHO published a "Framework for action on interprofessional education and collaborative practice." Interprofessional education (IPE) is now being conducted in various ways. We have been holding cadaver dissection seminars to provide opportunities for medical students, nursing students, and nurse practitioner (NP) students to learn together. In this study, we investigated the effect of learning about IPE in cadaver dissection seminars. The seminars were held for 5days each in 2021 and 2022 (the number of days of participation was arbitrary). In the seminars, teams of 3-5 participants with the same theme collaborated to dissect a single donated cadaver. Teams were made up of participants with different departments: 29 medical students, 12 NP students, and 20 nursing students participated in the seminar, and participants were surveyed before and after the seminars. The Readiness for Interprofessional Learning Scale (RIPLS) scores before and after the dissection seminar increased significantly overall. The scores of medical and nursing students increased significantly, but those of NP students did not significantly change. In terms of the number of days of participation, a significant increase in scores was found for participants who participated for ≥ 2days. Overall, a significant positive correlation was found between intrinsic motivation to learn and RIPLS scores. For medical students, a significant negative correlation was noted between extrinsic motivation and RIPLS scores. Cadaver dissection seminars conducted by medical, nursing, and NP students demonstrated IPE learning effect on medical students and undergraduate nursing students.
