I was once an RGN (Registered General Nurse) student. I went into nursing to be a missionary, not kill people, so when I found out there were secret plans not to resuscitate patients, and other ways they finished up without the planned resuscitation, I went on Channel 4 TV News in England to try to expose the practices. However I would describe the TV broadcast as a clever cover-up. They actively refused to allow me to quote evidence of a planned resuscitation that did not occur, even though the patient and relatives thought a resuscitation would be performed in the event of a cardiac arrest.
If you want to see just how bad the secret practices were just see the paper that was published by one of the hospitals I worked in, where I made complaints about subjects like "The Hollywood Code" "Light Blue" or "The slow code".
