Well, at least the wealthy end up in private rooms, which is a big help. If you are unfortunate enough to share a room with another patient, then either he will be sick enough that the staff keeps you awake half the night as they attend to him, or he will be feeling fairly well, and will insist on watching Family Feud all night on the TV mounted on the wall.
From what I heard most new hospitals have gone private room only for triage reasons alone - sure a broken leg isn't contagious but hospital bugs are downright nasty.
