Imagine you were a sort of "librarian of world-wide knowledge" that people would call to ask all kinds of questions they had. Imagine there were this one person who asked you a lot of questions about all kinds of mental health problems, and then also quite a lot of names of people, in particular during working hours. Are you telling me you wouldn't possibly get the idea from that that a significant proportion of those people would be their patients? Or are you saying that as long as there is no absolute certainty, sharing of medical info is perfectly fine? So, there shouldn't really be a problem with a doctor publishing the medical file of a patient in the local newspaper ... after all, how should the reader be certain that it's not just a fake of someone the doctor doesn't even know?
