In my opinion this is kinda rude as an intial action. if the person continues to go back to the topic, I would say having a chaperone would help.... idk why Interrupting the patient with a more neurtal topic isnt the answer
I just thought of the chaperone action as a CYA; if the patient tries to make a case, I'll have a witness. Plus, it'll probably make her come back with those complaints again. Switching to a more neutral topic likely won't work...the physician has probably tried that and she just comes back.
