getting certified in wound and ostomy care was the best decision I ever made in nursing. The training is very in depth and I have never received more respect from doctors, surgeons and patients. If you're interested in wounds, I definitely recommend it!
I work in both acute care and in home health, and often see patients in the home that I saw in the hospital, and vica versa.
Sure it's demanding, what in nursing isn't, but I'm way more independent, and don't have a supervisor constantly watching over me. I report to a team of WOCNs and we meet weekly to discuss policies, case studies, etc. It's a very supportive environment.
I don't like a lot of dramarama and adrenaline, either, although at times, especially in acute care, the productivity requirements can be demanding. In home health, I pace my wound and ostomy consults the way I want to, then go to a cafe to document. I also teach an occasional class in wound care, ostomy management, wound vac techniques, and compression dressing techniques. There's always more to learn and as a fairly new WOCN, I've found other WOCNs to be incredibly patient and helpful. We don't "eat our young" as I often felt in other areas of nursing.
Regarding if you should get some experience beforehand, it wouldn't hurt. I don't think that will affect your studies at all or your ability to be a good wound care nurse. You have to follow your heart. If you don't want to do other things, why put yourself through all that stress? It may affect other aspects of your career, such as how many years of experience, etc. Employers
still often hire based on years of acute care experience. You do get a pretty good background of anatomy and physiology , as well as etiologies of chronic wounds and ostomies. And way more in depth than you ever did in nursing school.
Hope that helps. Let me know if you have more questions.
