Answer this prompt:

You are a medical student. Another medical student, Sam, invites you to a study group with three other students. At the study group, you find that the students are using real cases from their clinical rotations. When you ask Sam about this, they explain that the group removes always patient identifiers and that they feel that current cases are a great way to learn medicine. What considerations should be made in this situation? Would you say anything further to Sam? Are there any other actions you would take?
