What outrageous claims? The post did not make any mention of safety issues. It only states the fact that CRNA's are practicing Medicine without a license. This is why "opt-out" is required because CRNA's are Nurses and should be supervised even if it is by a Dentist.
The "opt-out" law is a way of getting around legal and moral requirements that Nurses (even good ones) should be supervised. Or, do you oppose the very concept of Physician supervising advanced Nurses (not just CRNA's but every advanced nurse). The "opt-out" law is a cheap way of fixing a problem. The Surgeons do not want to be responsible for "supervising" a CRNa in any capacity. Particulary, if the CRNA is doing big cases.
But, if the Surgeon is making a lot of money off the CRNA's services (Plastic cases, Surgi-center, etc.) then the risk/reward profile becomes worth the burden. "Opt-Out" solves this problem for the CRNA and Surgeon. This is convenient but not in the best interest of patient care.
DD is just a Nurse. Albeit, she is an Advanced Nurse and possibly even a good one but Nurses should not practice Medicine without Physician Supervision/responsibilty. This principal holds true for Surgical Techs, PA's, RNP's, etc.
As for why there is no outcome data it is because CRNA "solo" practices exist in BUM F#@K Egypt or at private centers. As of yet, no major medical centers allow this type of practice. I guess the real Physicians at the major medical centers are not buying the crap your selling about "Anesthesia is the practice of Nursing" and not Medicine. They know the truth and realize the limitations of CRNA's. Unfortunately, the AANA and you do not. Hence, the battle between right and wrong or the ASA and the AANA.
AA's choose not to join the dark side of the Anesthesia world. I hope they never do. The AANA has $$$ in its sights and that is all that matters. Live long and prosper-AAAA.
