Wow. . . This topic is only one day old and already there are SIX pages of postings to be found.
I received an email regarding this topic. Usually I ignore emails about posts from bulletin boards like the one that was sent from allnurses. But this topic caught me eye.
No. I did not read every post. Too many of them. But it seems that the "control issue" has been clarified by the "original poster" (OP). Hopefully that's true. Since I am here already, I might as well give my "2-cents worth". It's summed up with this: HIPPA. Don't use patient names or anything super specific about a patient that can violate HIPPA. Otherwise, share, vent, seek answers to question, etc.
As far as preserving one's own anonymity. . . well that's a personal choice. I started out on this web-site using the first initial to my first legal name followed by my last name. I held that UserID for years. Now, it's just simply my well-recognized nickname since birth. Why? It's easier to type when I sign in. For me, i'm an open book and I could care less what others think about what I post. Not everyone shares this point of view which is to be expected and respected. So, don't share anything about yourself you simply don't want people to know. (And, as always, following this web-site's Terms of Service will go a long way in keeping whatever is posted safe, honest, respectful and following HIPPA.)
