Health guidance: the public is let into areas in which sensitive information is processed, so areas where health information is gathered or viewed on screen need additional precautions; screens visible to the next person in an admission queue and ward displays or whiteboards showing bed allocation are read by visitors, and such disclosure should be prevented, for instance by relocating or repositioning displays.
