In some cases (at least here in Argentina) the staff checks that the health insurance cover (partially) the cost of the visit and that the patient has all the correct forms and whatever is necessary. Also, open the door, so the doctor can start with the next patient immediately.
I am pretty sure AI can, at this point in time, not take any blood tests, hold a complex feedback loop with a busy doctor, nor do I want to put any blind trust into its health suggestions.
But that's me and as OP said, not everyone has the luxury of a working medical field.
