The problem is, if you say you cannot accommodate them, and will not source care for them, they could be housed in the most horrible care homes, the ones where there are loads of vacancies...... This almost happened to my mum. She had advanced breast cancer and severe dementia(she did not know who we were).
She had been in hospital with a uti and they wanted to discharge her. I live 90 kles away from her, my brother over 200. My step dad desperately wanted her home, to care for her. Problem was, he did not encourage her to eat - if she said she was not hunhry, he did not feed her. She had not been bathed for several weeks, jer nails were filty, her hair was matted, but they still wanted to send her home to him.
We pushed and pushed for continuing care, but in the meantime, I found a local, lovely home for her to move into. Brother and I agreed to cover the costs if needed (we knew that she was dying).
She lived their, happily, as far as that is possible, for 9 weeks before she died. We ended up just paying for 3 days care (?)
Had it been left to social services, she would have been homed in the most desperate, horrible care home. We could never have seen her in there.
I guess the moral is: what would YOU want if it was you? Go for it, and sod the expense!
