The answe to 'is it wide scale", I don't know, but I can tell you the same occurred when my Mother was admitted to the Heath after a fall in her Care Home. I was given copies of the documents which were to go to the Home's Doctor and in a small box at the bottom it had 'DNR'. At this stage of life she was had dememtia and was quite frail, but hadn't been in hospital for years - when she would have been fit and healthy. Neither I nor my Brother would have given permission.
