Who is it giving pause? There's tons of ambulatory surgery centers that only use CRNAs. **** when I had to go in for a scope, it was a CRNA doing the sedation, no anesthesiologist even in the building. Didn't you see the lawsuit where the plastic surgeon and his CRNA buddy left the girl unresponsive in their ASC all day?
I don't know who you're seeing who's pausing but it's definitely not the surgeons or administrators. The surgeons only think in terms of if it's a complex surgical case or not...not in terms of complexity from anesthesia's side.
This is how it all starts. "Oh NPs can do primary care because we need more primary care and my PCP just gives me antibiotics for my cold anyway so it must not be so complicated....Oh NPs did "fine" in primary care (bc it's terribly hard to measure outcomes in primary care) we need more anesthesiologists, so lets let them work by themselves...Oh CRNAs did fine, lets let NPs start running the ICUs". I mean we all know many of the existing "supervision" laws are supervision in name only. As long as you can get some sucker to sign off on your 10% of charts every month or whatever, they basically run wild doing whatever they want anyway.
