When Mother had xrays in the ER in May, I gave them a full copy of the advanced directives. That was May 2.
Today, when we went thru the ER and she got admitted, they couldn't find the paper work, and got another copy.
This evening, 5 hours later, I called the nurse's station, and they told me to bring in a copy of the AD because they didn't have one on file.
Lesson here: do not assume that because you have papered the entire town with copies of your POA or advanced directives, that they ever get into the proper file/paperwork/whatever.
This is one of the most high-tech hospitals anywhere, too, including NASA connections and little robots. I think I'll give them an earful when all this is over with.
