I would suggest a kidney transplantation, but due to his I
suppose higher age, he wouldn't be a good candidate. Younger
patients are prefered. I'm not wondering he doesn't want to have
the peritoneal dialysis, that idea scares me off too.
If your hospital can't provide dialysis for him and sending him
somewhere else, then they should find other hospital for him, where
he can get it done and book the dialysis for him there, preferably
a hospital close to his home.
Also someone with diplomatical skills should talk to him, calm him
down and explain him the whole situation of the hospital and of his
health state, offer him all possibilities, give him the feeling
that everyone is interested to help him.
He must be given the feeling, that someone cares to solve his
problem and help him, not the feeling that the hospital wants to
get rid of him. You must choose a psychological tactics. Doctors
often must use psychological tactics.
When he has the feeling that the doctors care and want to help him,
he won't get excited so easily and accept also the negative news
from the doctors without sending the medical personnel to hell or
having the idea of beating the souls out of them. As a government
servant he expects that the country for which he has been working
so long provides proper medical care for him.
