There is a massive difference in shutting them away because you can't be bothered to support them, and them needing proper nursing care 24/7.
And to be quite honest, it's not as simple as just putting them in a home. There are HUGE waiting lists and they're more likely to have home carers first.
My grandfather needs 24hr nursing care, something I can't provide while I have two young children.
Yes, he brought me up, and I've looked after him for as long as I can, but I can't be with him 24hrs a day.
He's now in hospital because of falls and is now unable to walk, eat or drink without assistance. Requires extensive personal care regarding washing and toileting needs and needs equipment to mobilise.
As other posters have said, you can only do so much.
Also, residential and nursing homes are not what they used to be. Social interaction is very important and they get this in a home. They have shows, tv, friends, it's like a holiday for them. Staff get them up dancing and they are happy there.
My grandfather is on a waiting list for the home that he had respite in a few months back, and I know 100% that he will be looked after very well.
Yes there are stories that you see about neglect, but thankfully they are few and far between. There should be more publication about the homes that ARE fantastic, and I'm lucky enough to have seen a few that are really really amazing with staff that deserve much higher pay. The staff I have witnessed are an absolute credit to the care industry and I couldn't thank them enough for all they do.
