Continuity mistake: During the scene where Dr. Chase and Dr. Cameron are out having a drink, Cameron picks up Dr. Foreman's cell phone. Before she does she takes a drink of her soda. This drink drops the level of drink to half full. When Foreman returns a few seconds later she suddenly has a glass that is 3/4 full. There was no time for anyone to give her a refill.
Factual error: When House is looking over his whiteboard of symptoms for the swimming patient, the symptom "Intercranial Hemorrhage" is shown on the board. However, this is an error. The correct term is "Intracranial Hemorrhage." Anything inside the head is referred to as "intra" not "inter." This is a common mistake for laypeople, however the highly trained and knowledgeable Dr. House should not have made that error.
