Horrible story, but according to the press here (in Florida) she had contracted one of those terrible bacterial infections and there was really no alternative. Her limbs essentially started to die, and she had developed gangrene in all of them.
I am sure she knew she had an infection and would need surgery.
I believe her complaint is the hospital was negligent in letting her caught the infection in the first place.
The "right to privacy" is a fiction, created by government apologists to shield it from having to reveal its activities. Government has, above all, the obligation to disclose, to everybody, everything that it does.
Some national security and perhaps police-investigation exceptions exist, doubtless. But in the main, government needs to be open about everything.
Ok. This stuff is fast moving and certainly lethal. But noone was able to talk with the husband and brief him as to the wife's problems? He could not have been far from the hospital?
The other question, is how did she contract the bacteria? If the hospital was in any way at fault, I could see why they are stonewalling the family. There is probably a medical license or two that could be at stake, not to mention the millions from a malpractice suit.
