Sunrise and UMC are larger level I and level II trauma centers, they have specialized ICUs. The St Rose Dominican Hospital system is a nonprofit Catholic organization with 3 hospitals. Smaller, may have the mixed ICU you. The Valley System is about the size of St. Rose and may again have that mixed ICU setting. I've worked at three of these. St Rose pays the best & the staff seems content, Sunrise (HCA facilities - they have three hospitals) pays about medium, the Valley System probably pays the worst of the three. I would recommend signing up with an agency and floating to a few different hospitals. It seems like different people like different environments. In general I haven't had a big issue with satisfaction at any of them. There will always be issues at any facility you work at.
