Here's the thing though, doctors have a long storied background of not knowing what the hell they're doing. History is filled with stories of hilarious medical ineptitude, and in all likeliness, today's medical practices will be similarly snorted at 100 years down the road.

Difference between the vacated position and the vacant position. 'Vacate' means to leave a previously occupied place, for example, a seat or a house. 'Vacant' means a place that isn't occupied at present. The status of the chair or the house (or where ever it may be) after a person vacates from it is 'vacant'. So a 'vacant' position means that the position is unoccupied now. It may have been vacated or it could've never been occupied in the first place. A 'vacated' position means that there was somebody who was occupying that position and now, that place is unoccupied. That is the significant difference between the words. This is the Merriam-Webster definition of vacant and vacate.
