If I was a doctor and recommeded a patient have a certain treatment and they refused on religious grounds I would then not be their doctor but advise them to find another doctor who will honour their beliefs.
For doctors to be restricted this way by patients and then when things go wrong the patient sues the doctor ,how pathetic is that .?
Doctors nowadays need to protect themselves from patients that are too eager to sue them for unforseen occurences that happen.
And for Jehovahs Witnesses to do that just shows where their priorities lie. $$$$$$$
