There are also some AANA papers out that can be destroyed.... the problem is making sure people really understand the shortcomings of their literature and why this means bad news for the patients. Obviously the AANA concludes that CRNAs are "as competent", but their data dont really show that.
Here is one for midwives:
http://www.ncbi.nlm.nih.gov/pubmed/17542818
In their study they say essentially "we gave midwives low risk patients and compared their outcomes to general hospital admissions. In all, doctors were more likely to use intervention methods than midwives (who are unable to anyways, nor would they on their low risk patients), therefore broader use of midwives will reduce physician interventions in childbirths"
So basically: "since we didnt kill more babies in the group where none were going to have difficulty anyways, we probably won't kill any in groups where they may have higher incidence of complications"

You could pair papers like this with method assessment data of the methods they aim to reduce and present the
benefit that such interventions bring in terms of saved baby lives. Town halls love saved babies.
The biggest problem of the CRNA papers is they tend to hide their numbers and the ways by which they arrive at conclusions. They do apples to oranges comparisons. One of their biggest papers shows the highers death rate among anesthesiologist-only practices.
HOWEVER: they do not specify how they are calculating this. It looks like they are keeping it at the total number of patients seen rather than normalizing against # of CRNAs and anesthesiologists, which would give a per-practitioner death rate. There are oodles more anesthesiologists. Coupled with the fact that most often patients are pre-screened for simplicity to go to CRNAs.... no sh** the docs are involved with more mortality. They get way more patients and the CRNAs still have on their training wheels. I also didnt see a breakdown of comorbidities that were looked at.... if I decide to take a study break later I will look for a non-AANA paper on the subject, but I feel like I would have known about it by now if it existed.
