How would you handle a patient who wanted and needed knee surgery but who refused on religious grounds to accept any blood products?
Frank M. Brown, MD, an orthopedic surgeon at the Asheville (N.C.) VA Medical Center, was sued by a Jehovah's Witness named William Clinton, who claimed Dr. Brown refused to operate on him and thereby violated his First Amendment right to freedom of religion. Dr. Brown says he didn't refuse, but he did try to talk Mr. Clinton into reconsidering his refusal to accept blood products under any circumstances.
