In the UK capes used to be part of a nurses uniform, allthough like caps, and seperate cuffs they are no longer worn at the majority of hospitals Allthough soem private hospitals and military hospitals still make female nurses where capes.
I have worn a cape once, the ward I was just on, (as a student on placement) had a cape, which was generally worn by memebers of staff to nip outside and smoke in. Quite a lot of wards have capes for the self same reason! I borrowed the cape to go over to ICU to get some blood results, as I didn't have time to get my coat out of my car.
Wearing the cape got me some strange looks, but it was really warm and didn't mark my uniform, with crinkles like coats do. Also the hood was huge so there was no chance of me getting wet. It was snowing really heavily, and I never felt the cold, it could have done with pockets but it was very practicle apart from that.
