With the rapid advancement of artificial intelligence technology in medicine, there is a growing demand for medical school curricula to educate students on its use in accordance with evolving legal and ethical standards. Based on previous research findings, we implemented a problem-based learning (PBL) program for fourth-year medical students-prior to their clinical clerkships-to address legal and ethical issues related to AI utilization. A novel PBL case, featuring a medical student responding to a patient who over-relies on a diagnosis from an AI-powered medical consultation app, demonstrated potential educational value, as reflected in student feedback analyzed using the ARCS model.
