SOme serious misunderstanding and misinformation.
Do not attempt cardiopulmonary resuscitation is a way of protecting patients from inappropriate and overzealous care. It allows a dignified and natural death instead of broken ribs and tubes at a point when resuscitation would be futile.
Trusts have marginally different policies but are broadly the same.
It is a clinical decision. Usually a decision made by a more junior doctor has to be signed off by a consultant within 24 hours. Consent is not necessary as it is about not giving specific treatment rather than giving treatment. Much as you wouldn’t consent to not having chemotherapy if it wasn’t in your best interests and wasn’t likely to be effective- but hopefully the medical team would explain why.
The guidance is that the decision around CPR should be discussed with any patient with capacity to be involved. There is no obligation for family to be involved if the patient chooses not to. Families should be informed and involved where a patient lacks the capacity- but they are not consenting.
Most resuscitation attempts are unsuccessful- despite what is portrayed on casualty. Something like 10% of patients are resuscitated successfully- although many of those don’t jump up and start dancing.
In acute illness the decision should be kept under review as the patients condition changes - so a younger patient in ITU, for example.
Most hospices won’t admit patients where end of life discussions have not taken place and a DNACPR is not in place.
DNACPR is not the same as stopping all treatment. It refers simply to withholding intervention if the heart stops beating. The person should still receive treatment for conditions other than that - urinary tract infections, broken leg, burns etc. Withholding all active treatment is a separate discussion.
