Correct me if I'm wrong, but is doctor-patient confidentiality is even relevant to this case? This isn't a matter of a doctor illegally sharing Selen's info. This is a matter of one lawyer sharing Selen's info with another lawyer with some kind of NDA attached, and that lawyer then disclosing a small part of that info in some form to the rest of the talents. We don't know what that NDA looks like, we don't know if its enforceable, we don't know what it specifically asked for, and we don't know exactly how or what the talents were told about the information.
