I am a volunteer at Newton Medical Center, which isn't too far from Rockdale, and I have heard many patients prefer Rockdale. My grandmother has lung cancer and often goes to Rockdale for procedures because she prefers it to Newton and even Atlanta-area hospitals. I know a RN and phlebotomist who work for Rockdale and both are very happy with their environment. Sorry I can't say much else about it!
I believe the nurse-patient ratio on the floor is around 5:1, but I've seen it as bad as 7:1. It's in the older part of the hospital if I recall correctly, so the rooms are a little bit of a tight squeeze. I think the floor also does oncology patients. Other than that, I don't really know much. Sorry! Piedmont is in the process of taking over, so things are changing a lot.
