I think that we need to maintain perspective & look at what tools we are given.
The most important of these is our protocols and, to ensure we 1. do the best for the patient & 2 CYA, we need to follow them, irrespective of religious beliefs or not.
This does not mean we blindly follow the book, but to refuse treatment to someone because you have a religious objection in my opinion is reprehensible. It is your choice not mine to take this stand & your beliefs should not be forced onto me as your patient.
Also, here we are in the worst case, answerable to the coroner who would defer to our protocols & tell us that we are to use them and if we don't agree with them, argue for change showing clinical proof and outcomes resultant from alternative therapies or leave.
Stay safe
