You're confusing mid-level practitioners with scribes. Lawyers have paralegals. Physicians have PAs or NPs.
The existence of someone whose sole job is just following a clinician and documenting for them is absurd. Medicine in the past was fine with paper charts. Sure there was some inefficiency with collecting information. Medicine these days is actually less complex than in the past because answers are more readily available with diagnostic testing. Why is more documentation required today compared to the past?
We should all strive to simplify medicine, not facilitate ever increasing unnecessary complexity.
