Ah yes.. I get it. If you were staying at the same facility and just asking to stay on in the ICU you were already trained in, that may work, but it would be a whole different deal going to a different facility.
Sounds like you are itching for a change and this deal looks like a good one. I'm guessing they are wanting a commitment that you will work for them in this role for X amount of years. Just make sure you are wiling to do that and worst case scenario you try something different after that. Nursing is good in that way.
As for what makes it worth the job change. Like you I'm frustrated by the poor communication/coordination between nurses and doctors. Not that we don't have some wonderful doc's and PA's, but we also have our fair share who I know my shift will be more challenging because of and my patients will suffer in the care they get. I'm tired of that. So far as a WOCN I've gotten more respect from physicians and I feel like I'm actually working with many of them who I was previously just doing tasks for.
More importantly I like the work. I love the education aspect - educating staff, patients, family members. I love the autonomy of making my own schedule of my days activities (for the most part), the ability to get creative (seeing an area of weakness i.e.. several patients with trach ulcers and being able initiate change to reduce this), the diversity of my day (consults, presentations, supply chain meetings, surgery rounds, etc), and the movement and interaction I have with the rest of the hospital.
Above all I like not leaving every shift feeling like I didn't give adequate care. Not that I was giving poor care, just that there was rarely enough time to give everyone the care I would have wanted. Oh, and eating lunch isn't a bad thing either
Not that the life of a WOCN isn't busy. I have more than enough to keep me busy and my days are never boring. If you are a thrill seeker (can't wait for the next code to be called and always request the most unstable patient) then you may not find wound/ostomy care quite as satisfying as I do. If however you like a different sort of challenge, one that involves coordinating with most every discipline in a hospital (PT, risk management, SW, surgery, etc), means being the go to person and "expert", and being independent and self driven, then I think you will love it! Good Luck!
