Are all SNFs the same

Please correct me if I am wrong, but I assume SNFs are state regulated? So, does this mean a hospital-affiliated SNF (ie. on hospital grounds) is the same as an 'independent' SNF. Is there a difference in acuity, patient ratio, (RN) skills used, RN responsibilities between the two settings. Or, or is a SNF always a SNF, regardless of where it is located? How are the RN roles/expectations the same or different? Is there a big difference in compensation and will working on a SNF floor (located inside the hospital) be considered as 'acute care expereince' for when I want to transfer to med-surg or another specialty area? Or will I have to move from SNF to med-surg, and then to a specialty area?

Can someone please help clarify this for me? I am not finding a lot of info on the internet to help me. Thank you!
