You could be sued for not keeping up, at least in Israel. I read about this in TheLancet. In the News section, Robert Fishman reported that the Supreme Court of Israel "upheld a lower district court conviction of malpractice resulting from ignorance of the current medical literature."1 The case involved a patient who underwent surgery for what was thought to be a brain tumor but who actually had a rare form of multiple sclerosis "that behaved like a brain tumor." The judge ruled that "the physicians were negligent for not keeping abreast of the published professional literature, which would have alerted them to this alternative diagnosis."
