Although attempts to teach medical students about nursing have become more frequent, nurses who have lectured to medical students and have been involved in their practical training have rarely published studies evaluating their training methods and objectives. This study was performed to clarify the significance and problems of such teaching. Nurses now participate in the education and training of medical students in at least half of medical training hospitals and schools. They thought that this is a unique and beneficial educational opportunity and had high expectations. However, four main problems have been identified: the motivation and attitudes of medical students, the time and environment for training, the understanding of clinicians, and the problems of nurses, such as lack of educational experience.
