During my intern year, I learned a very important lesson:
Never let the family of your patient see your very detailed discharge summary, unless they are already out the door. I can do without being questioned on every sentence of my discharge summary.
Wife of patient: (furious) "You doctors keep saying that he has sinus problems, but he doesn't. He can breathe fine. This is a mistake!"
Me: "Where did I say he had sinus problems?"
Wife: "Right here! You wrote he had sinus bradycardia!"
