You have to understand that the push for the DNP has come out of the AACN (Association of colleges of nursing) NOT the AANA. So all those CRNA schools
based out of SON, as opposed to SOM, must convert to the DNP if they want to maintain accredidation as a school of nursing. The controversy on the CRNA side is what to do with those programs based in SOM. Most of these programs do not have to have a nod from the AACN to keep the doors open. We (SRNA/CRNA's) have traditionally done things as a profession-All for one, one for all type governance. The DNP is not going to affect practice in a meaningful way for CRNA's, but history tells us if a large portion of the schools are forced to do it, all will follow suit for solidarity sake if nothing else.
The DNP is a practice doctorate and as such I think there will be mechanism for all CRNA's (MS/MHS/MSN/MEd) to bridge easily to the DNP. Our programs as a whole have sufficient credit to only require approximately 6-12 months of full-time attendance for DNP completion. And we are talking about NP full time reference here (max 12 credits) as opposed to CRNA full time (13-18credits) so work is a definite possibility while in school.
Here is a plan of study from a "top tier" Nursing school
You will notice that 15 credits are "specialty elective"- which has no course description.
I will finish with this: I personally think the DNP is a brainchild of a bunch of dean's of nursing schools to boost tuition and is going to be required for all APN's and will add nothing to any of the roles. However, I will get one if required by the AANA and hate every minute of it. If I wanted a doctorate I would have enrolled in a MSN/PhD program.
