When I had my surgery, I had all the pre-op testing a few days before. When I checked in to the Guest Services desk that morning, all the paperwork had already been taken care of, and they put me in a patient room where they put on my bracelet, started the IV, and did the other last minute things. This patient room was not on the cardiac floor - it was a room specifically used for people who are having OHS. Then, they transferred me directly to the OR for the surgery. This is standard practice at that hospital for OHS, but not for other surgeries. They said that they want as little stress as possible on their OHS patients, and that includes making sure they are comfortable prior to surgery, not laying on a gurney, half dressed, in a cold room with a bunch of other people.
I can't imagine having to keep a bracelet on for a week, especially with stickers. I was told I had to wash thoroughly with antibacterial soap (Hibiclens?) the morning of the surgery, so I'm sure it would have fallen off.
