UGH, please, as future physicians, don't buy into the BS that this is a good thing, by any means. If you'd like to know where this road of 'filling a crucial gap in primary care' is headed, check out some of the CRNA versus Anesthesiologist threads in the gas forums, or read about the 'Nursing Dermatology Residency' offered at USF.
Additionally, as far as the 'evidence' is concerned, it's out there ... in spades. The only problem with all the studies that PROVE NPs are on par with DO/MDs is that they are all financed by the nursing groups, are horrendously flawed, only monitor the least complex patients over a checkup period of less than 6 months, and come to erroneous conclusions.
I urge anyone who sees this as a good thing to just check out some of the threads on SDN, read some of the replies as where DNPs/NPs see this going, how they feel about physicians, the actual training these individuals have, etc.
