Maybe it depends on the hospital, but I've always got them when I've gone to the ER. I remember getting one when I was a little girl and I freaked because I thought I was getting admitted! LOL!
Yep...they ALWAYS do those ID bracelets now. They have info. imprinted on them that can be scanned into the computers and bring up medical history. If you keep yours, and take it with you the next time you go to the hospital it saves a lot of time. No one keeps them however, but you should.
