Don't know about your RN colleagues, but the 'ologists are gonna absolutely LOVE you for this line of reasoning!!
Taking CRNAs, and the autonomy issue, out of the equation, the AAs stand to lose financially, BIG TIME!! 'ologists are nothing if not about control..and once the LIP status of CRNAs would go away, the AAs' salary is going to be gradually wratchetted back further and further. It's happened many, many times before, with CRNAs and it will happen with AAs as soon as the 'ologists feel like they can get away with it.
