I spent a month at one of the top US hospitals and I witnessed crazy unhygienic practices. The most common one is when the nurse assistant puts on gloves to clean the toilet and other items touched by bodily fluids and then proceeds to clean the food tray with the same gloves and often even adjust the IV lines. I got a lot of nurses angry by pointing this out (it must suck to hear someone else tell you that you're doing your job badly, but still). My mother caught a C diff infection. After that, I carried a clorhexidine bottle with me to the hospital and cleaned all surfaces that contacted food with it.
