I used to be on that fence, but I am more and more for solo providers, in whatever form, shape or color. I don't want to supervise people who think about themselves as my equal. And almost all of them get to that level of arrogance after a decade or less, whether they are NPs, PAs, CRNAs or AAs. It's just human nature, when one is told all day long that one should practice "at the top of one's license", that they are "professionals" blah-blah. That's what the bean counters want, that's what they push for, cheap labor with maximum profits and minimal risks for them.
I don't want to spend my career training my or my young colleagues' future replacements. I don't want to be liable for their mistakes. I don't want to be responsible for 4 times more patients than I should, just because I have to use physician "extenders". I want to provide safe and excellent care, at my standards, and that will never happen when I am not the one calling the shots.
So, from where I stand, I'd rather have completely independent CRNAs than AAs. Because I will probably always be just an employee, I don't want ACT in any form or shape. I have been their preop monkey a few times and that's not medicine, whatever the money-racking partners on this forum like to tell us. And shame on the ASA (and any medical organization) for supporting the team-care model wherever they do it. That's how we got the general public believing that doctors are only interested in money, because the good nurse (practitioner) gets to spend much more time with them than the bad doctor.
I had a needlestick injury this year, so I went to the ED after hours. My insurer got a $2000 bill for me spending literally 2 minutes with a rushed EM doctor, 2 minutes with his resident, 10 minutes with various nurses, and more than an hour waiting in-between (especially for the nurse/tech who drew my blood). The doctors were overworked, and the nurses/techs took their sweet time. Not only at no times was I given/offered proper counseling, but they managed to send my HIV test under my real name (while telling me it was anonymous, as it should have been). Absolutely shameful. That's what happens when there are too many cooks. And they knew I was an attending physician at their big box academic hospital. Imagine the level of care a poor soul gets. And they want me to let the midlevels run amok on my license and under my good name?
Mark my words: AAs are just CRNAs in a sheep's clothing. Just give them 15-20 years. Of course, if one doesn't have 20 years till retirement and/or one is racking in the dough as a partner, they are a godsend in a state where CRNAs are now independent.
