The trouble is, that they are getting the propaganda out unopposed by us. No one in the powers that be will look at who puts it out as a bias point. The powers that be will look at this as research done by "experts" in the field of anesthesia ("hey, the AANA backed the study, the *must* know what they are doing, and we haven't heard anything from the anesthesiologists, so it must be true.") Our inactivity is all they need to minimize or eliminate our specialty, through this type of propaganda swaying public and political opinion against us.
There needs to be more aggressive work done on our part to get the information out that CRNAs aren't the alpha-omega of anesthesia, and in some times, can be risky. It has to be done in language that is accessible to the public and the political for comprehension.
The only reason they are cheaper is the liability issue isn't there. When (not if) they are held liable as independent practicioners, they will not be as cost effective.
