I must be very naive. I don't have a clue as to what most of the acronyms that are used on this website mean and I have been through all this with my husband and went with him to every appointment and meeting. I have been advised to put my signature in but don't know any of the lingo that everyone else is using. I don't remember anyone (doctors,nurses, etc) using any of it with us. The only one I can figure out is SCC.
