In parts of America, most hospitals are run by religiously-inspired (faith-based) organisations.
That's a horrifying thought. Because if a medical procedure goes against the faith system of the hospital, they won't provide it. I don't think that there are any Jehovah's Witness-based hospitals, but if there were, you wouldn't get blood transfusions there. Or maybe a faith-based doctor decides that your best treatment would be to be prayed for?
As a practical matter, a Roman Catholic hospital might refuse to perform a procedure that would kill the fetus but save the mother.
So maybe you could choose to only go to a secular hospital? Good luck with that; when you need emergency treatment, you don't usually get to make a considered, informed choice. Plus, there's no requirement on a faith-based hospital to disclose which procedures they would refuse to do.
Thank god for out own dear NHS!
