Slim to none. There was one study done in the hospital that I work at(not public, sorry) that showed that the doctors(not nurses or admin staff) were the ones not complying with the hygiene requirements and they were the ones causing most hospital acquired infections. Of course the doctors are not held liable for such behaviour so nothing can be done to fix that.
