I showed your article to my wife, a nurse with 20 years clinical experience, and her comment was " There are about 10 different things in that story that would get my, or the hospitals, credentials revoked."
Of course that is in the "Bastion of all that is Violent, Crass and Not Nice" hereafter known as America, for brevity's sake.
I'm not naive enough to think that that the American health system is perfect, but your sad story only hardens my belief that further socializing the healthcare system in the U.S. is clearly not the answer.
You have my deepest sympathies on the death of your uncle. :-(
