Interprofessional education in geriatric medicine: towards best practice. A controlled before-after study of medical and nursing students.

Educators with nursing and medical backgrounds delivered geriatric IPE through case-based PBL. The optimal learner group size was determined. The equal numbers of participants from each profession for successful IPE are not necessary. The IPE delivered by clinicians and senior nurses had an overall positive impact on all participants, but more markedly on nursing students. Surprisingly, it had the same impact on medical students regardless if it was delivered to the mixed groups with nursing students, or to medical students alone. Teaching successfully addressed students' concerns about joint learning and communication and ethics were most commonly suggested topics for the future.
