Yeah, this is a problem more people need to know about. My Dad was cavalier about pressing the red 'help' button when Mum fell over, to get someone to come round and get her up. All very well - but when this happened, say, three times in maybe half a year, they said, into hospital she goes, she has a urine infection. And we'll keep her there.
Meanwhile, the ward doctor put my mum, who has Parkinson's, back onto Motilium. Now, google motilium and try to figure out why this isn't a good thing to give someone with Parky's. Here's a clue: a side effect is that it inhibits the dopamine receptors. We only figured this out later.
Anyway, soon it became a case of, your dad can't really cope anymore, can he? And look - she's obviously deteriotated. It's time for a home!
So that, it seems to me, is what that red button is for. Push it once too often, and it is used as evidence that you either get full time carers in, or it's a care home. That decision has cost us something like, what £60K that last year. Or rather, it's cost my Dad, or our inheritance (an inglorious comment I know, but still). And all because it was too much to send a couple of burly guys to help pick my Mum up off the floor. Honestly, had we known I'd have paid for a taxi and come round myself, would have been cheap at half the price.
