There was a case like this on a TV documentary recently. An elderly lady (can't remember where she lived) who was bedridden, kept calling the ambulance service because she'd slipped down the bed. I think over a 2 year period she'd cost the NHS £58,000. Social Services kept trying to persuade her to go into a care home, but she was adamant she wanted to stay at home. Her husband, who wasn't in the best of health himself was quite prepared to go into a care home with her, but she wouldn't have any of it.
