I am finishing my second assignment in the IMC and it hasn't been a bad assignment. The staff is very friendly and helpful to travelers. I have not have to float for the entire six months (knock on wood) and pt ratio is 5/1 at this time with a tech to help. Hope this helps.
Personally, I think the healthcare in Vegas is scary! When I was there on assignment (at Valley in the IMC) it was HORRIBLE! (I was there for my first assignment in 2001). Told everyone there if I got sick: SHIP ME OUT!!!! Lazy CNA's, staff didn't know what the heck they were doing (one RN actually played a LARGE part in a patient dying!!!), management............well, they didn't actual manage!..........was like a turnstyle! The IMC at Valley had 5 managers in 18 months. The one that was there when I was left in the middle of my assignment!
Have heard most of the other hospital are nearly the same. There are some good floors, but very few. Have a traveler friend who was with me at Valley that said Sunrise was a little better.
You might try the new hospital that they have opened there. I don't remember what it is called, though. Have also heard the St. Rose (in Henderson) has finally started taking travelers. They say it is very nice there.
