I apologise if I offend anyone in my ignorance here, however, I have just watched a programme which had a storyline of a Jehovah's Witness being ill and requiring an operation, which possibly meant a blood transfusion. The patient refused to have the operation because of her beliefs.
Now, this is what got me wondering, what if the situation is that the patient is JW and the doctor is also JW and this situation arises, does the doctor refuse to do the operation? Do they mutually agree not to do it? Or does he put the patients needs before his (and possibly the patients) belief system?
A doctor agrees a moral oath that he/she will treat anyone who is need of help. I can't see that being an issue for a doctor. I think a person (JW or not) can refuse treatment. I don't think it's right if a parent refuses treatment to their child as the child isn't old enogh to make that decission or have it taken away!
The doctor must put his beliefs aside and provide care whatever the situation, the patient of parents of patient have final say even if it is life or death, but I have heard of muslim doctors refusing to do or put forward women for abortions.
