CRNA research presentations

I was hoping to meet some CRNAs when I present in April at the Midwest Nursing Research Society, but to my dismay, there is not even one CRNA who is attending that conference. Pain Management is one of the central themes at the conference. Do CRNAs present their research in AANA conferences only? I admit, I am very surprised at the disparate amount of research from CRNAs when compared to other nursing specialties. Does it have to do with professional alliances?
