That's very interesting, and explains many somewhat baffling experiences. So most of what I tell or give a doctor is effectively lost? That's the perspective from this patient, who finds it very frustrating to repeat myself, that the doctors are ill-informed and often perform that way.
But being open-minded: Is it that why I tell (or what most patients tell) the doctor isn't really useful to them? What is useful? Or is it just a consequence of time pressure?
