Hi, It's "Marsha" and back in the "olden times" before stoma nurses, all they offered were ostomates who were volunteers from one of the Ostomy Association. I think it was a good idea back then, and it is still good now! Go for it. But you might meet some "territorial resistance."
Like all things, even back then, there was a "procedure," and a doctor had to authorize or request a visit from a volunteer while he/she was in the hospital. I felt as you did and wanted to "give back," and was a volunteer visitor for anyone who requested. In fact, that's how I met my husband. After speaking to him twice, he didn't want me to visit "as an ostomate...he wanted to ask me out on a date." But that's another story. I especially wanted to visit children, and in doing so, often had to counsel parents.
I tried to start an Ostomy Assoc. under the banner of our local hospital, which is very active as a community health center. They didn't feel there was a "need," an answer which really upset me. They said that their "wound care" nurses took care of that, or they called in the Visiting Nurse Assoc. The administrator completely missed the point...It would be advantageous to have an actual "ostomate" on call to visit new ostomates for added support. If I decide to pursue it, I would try to go through the local UOA chapter, become a member, and an "official volunteer," just to give yourself more "credibility." It will be interesting to see what you encounter when you try to "help."
Good luck,
Marsha...
