Want to leave bedside nursing. How can I get into case management?

I don't seem to be cut out for hospital nursing.
I've been an RN for 5 years now. Spent a year and a half doing cardiac nursing in a hospital. Burnt out. Tried PACU, and burnt out also. Tried hospice nursing, burnt out again. Now I'm back to working full time night shift in another hospital, floor nursing. I've only been there for 3 months, but I already know that I'm not the right fit. I can't seem to handle all the stress of bedside nursing. Time management has always been a struggle, so trying to juggle 6 patients for 13 hours is overwhelming to me. I hate it.

I want to leave bedside nursing. I do not want to do hands on patient care nursing anymore, it's making me emotionally sick and physically ill. I want out.

I am curious about case management. Particularly case management jobs where you work in an office. But how do you go about finding these case management jobs? What are the qualifications for entry level case management? I've seen very few job postings, and the ones I've seen say previous case management experience is required AND certification in case management is required. How can I find a case management job that does not require CCM certification and previous case management experience? Plus, in this current horrible recession, are there even any case management job openings?
