I have spent several years in-hospital, unfortunately. I was in the highest security facility in my state. A quite famous hospital. Books and movies made about it. So on. Anyhoo, I had to undress in front of about 6 people and then shower and put on scrubs when I was first admitted. Not a pleasant experience. But there were some super-dangerous people on this ward where I was, so they were probably being extra cautious about people bringing potential weapons in to the hospital.
