I must disagree with your assumption of patients being sedated to death. That is an incorrect statement. Further DNR is entered on a physicians order only. A hospital cannot do this on its own and I know of no physician who changes a code status without a witnessed conversation and very clear communication.
“A hospital cannot do this on its own”
I don’t know where you work but you need to get out more
Hospitals have done this and ARE doing this. My nurse practitioner cousin who works in a university tertiary care hospital in one of the largest cities in the US called me to say how distressed she was that COVID patients in her ICU were marked as DNR, which is just one of a multitude of examples I can cite.
Family consent is not being obtained. Are you aware of how the CARES Act stripped patients of their rights? Hospitals have been empowered to do this garbage and the ghouls have certainly seized the opportunity
