Isn't it dreadful that the Surgeon didn't ask at the initial consult, who was going to care for your Aunt after discharge?
A Social Worker should have been in to talk with her whilst she was being treated. There really is no joined up thinking these days
However: without being rude, can she really not afford a week in respite? It's not a lot for full B&B, assisted bathing, company. She won't then have to wait for carers to go in, she may well have eye drops for a while too which as we know, can be difficult to get into the eye without missing.
Do U know her well enough to suggest that she should take the advantage of being spoiled for a week in the care home? What else is she going to spend the money on if she does indeed have savings. If she doesn't then that care should be free anyway.
