I've been doing some searches on this as I would like to move to Italy in a few years. There are some universities that offer advanced nursing degrees in Italy. I'm not sure how that translates into jobs, however. i don't believe there's anything like a nurse practitioner. I am a WOCN (Certified Wound, Ostomy & Continence Nurse) and I know that both wound and ET nurses are specialists in some hospitals.
As far as licensing, I'm still trying to figure this out using this Italian website: http://www.salute.gov.it/professioni...riconoscimento
(for determining/applying for degree equivalencies)
I believe you have to send documentation to the Ministry of Health to get an approval if the education equals the italian nursing schools. Then you have to apply in the regional office http://www.ipasvi.it/
it seems a little complicated but not nearly as complicated as what foreignors who want to work in the US have go through. I think you also have to take a language exam, as well. Obviously you'll need to speak Italian well.
If anybody has any information, as well, please let me know. I'm especially interested in talking to italian nurses who specialize in wound, ostomy and continence care.
