Terminology is important, and the medical profession is acutely aware of non-medics appropriating job titles that are potentially confusing for patients. Couple of examples:
What's the difference between a Consultant Podiatric Surgeon and a Consultant Orthopaedic Surgeon? The answer is a huge amount in terms of qualifications, training and experience, but for a patient presented with an individual wearing those badges, they may as well be the same. The former should have a sign with flashing lights saying "this person is not medically qualified".
Then there was the patient's relative who was referred to as "Mr X" and corrected me saying "It's Dr X, actually". I naturally then switched from plain English into medical jargon when explaining the situation only to be stopped to ask what I mean by metastatic neoplasia in the distal neuraxis (or whatever, made up for illustrative purposes). He had a doctorate in geography or something. (And before Roger Mexico chips in with only PhD holders being proper doctors, and medics not, it's the popular perception that is key here, rather than the academic rigour)
So the profession is currently in a battle, and seemingly tying itself up in knots, over what we call Physician Associates - should they be Physician Assistants, Medical Helpers, Doctor's apprentice or what? It's a bit like The Office - "You're not the assistant regional manager, you're the assistant to the regional manager". They're also in dispute as to how they should be regulated - GMC or HPC? Currently it's by nobody.
