But Dr. House almost never accepts the wishes of patients when those wishes don't put postponing death above all other considerations. It works on the show, because it almost always works out for the best on the show, but the logic is not as compelling in the real world, where it is not always easy to be sure which choice will lead to the best outcome for the patient.
“In the program, it looks like the doctor knows best. And that’s one of the things that one has to fight in medicine, is the idea that doctors do know best. They may know medicine best, but they may not know what’s best for patients, because patients have all sorts of priorities and preferences and values. And it is not necessarily maximum length of life or maximum health.” - Bioethicist Mark Wicclair, PhD.
