How can he do this? Don't we get a say? Yes, Dad has vascular dementia, but only diagnosed 4 days ago! Dad is currently on dialysis (started 10 days ago) and with his improvement of mental state, he's looking forward to being discharged next week (whether that be into a care home, or to his house, with a care package in place) and have outpatient dialysis 3 times a week. He can still have a good quality of life, he can see his eldest daughter turn 40 in the summer, he can see his younger daughter get married and start a family, he can still be a husband to his wife.
If this was an end of life decision, if he was just talking about if and when dialysis treatment is withdrawn and death for my Dad is inevitable then I'd understand this. But no, the consultant said for all the time Dad is under his care, in that hospital ward, if for any reason, his heart stops, they won't resuscitate.
