Utilization Review question-need expert advice

Hi
I need some advice. Thanks in advance. I have been out of the hospital for a lot of years and have been in clinical research, monitoring drug studies. I do a lot of chart and data reviews according to FDA regs., etc. I work with a lot of technology and am on the phone a lot, work with clinic staff to solve patient issues, etc. This work requires a lot of travel. Since I can't travel anymore, I have been researching UR and case management options. It looks interesting to me and I think I would be good at it. Question: how likely is it that I could get a job in UR without the recent hosp. experience? I live in a state without a lot of job options, such as insurance co, etc. How about a hospital or managed care (Humana, Cigna) UR position? Would you recommend any coursework or certifications such as McKESSONs CPHM? I have a BSN and current RN license. Would a CM position be out of the question?
