There is a huge difference. Hell, NPs only have 500 required hours of advanced clinical training over the entire course of their degree. That's ridiculous, a resident knocks out that many hours in 7-8 weeks. Most of the degree is management and the BS that is "nursing theory." They claim that their years of nursing training substitute for the lack of advanced clinical training. But they were not operating at an advanced level, so it really doesn't substitute for anything in my mind. It's like saying you can be the general manager of a Wal-Mart after 8 weeks of training because you totally know how everything works because you were a cashier for three years first.
At least PAs receive legit preclinical foundation years that aren't about touchy feely theory BS and are just straight up science, followed by a minimum of 2000 hours of clinical training at the advanced level. APRN education is garbage, aside from CRNA and neonatal. General family medicine and adult acute care APRN training is an embarrassment, and should have substantially increased clinical training requirements.
I am all for APRNs having a place in the system, but they should have to earn it via an education that is significantly more substantial than what they currently receive. BSNs are well trained for their jobs, but a lot of APRNs, especially the ones that went right into grad school after receiving their BSN, are downright scary.
