It was more "why are we doing this?" and "how does this improve things?"
The reality was, it was (is) a waste of time.
If it was a critical patient, the Dr wanted to talk to you anyways, so no need to notify twice. (Via phone with the Dr AND radio to ED front end.)
If it was BLS, the PT would wait in line with everyone else. Treatment didn't change by calling ahead.
Hospital status is communicated to the crews electronically and the patient is informed so there is no diversion discussion needed via radio.
Just a thing of the past for now... (always subject to change)
