But they could refuse to accept the consequences were their fault. That can be not uncommon - it’s everyone else’s fault not the person’s. They can’t (or won’t) link the consequence with their action or non-action.
I mentioned choices earlier and I think that’s a good way to deal with people like this woman. As said, the fact she’s got all her stuff piled around her doesn’t look safe (or hygienic) for anyone. Most hospitals are very strict about keeping things out of the way so the floor is clear. Yet they appear not to have been strict about this with this woman. Maybe if they had been able to, that might have helped a little.
Who brought all the stuff to the hospital? If it was her mother or the previous care home, why didn’t the hospital refuse it? I guess she refused suggestions about where to store it by simply saying No when offered. But, if she was offered a choice then that might have worked better, and might have facilitated the removal of the excess stuff. That choice should then have been implemented. If she refused to opt for either option, the consequence of that should have been made clear and actioned, eg “You can chose A or B, whichever you prefer. If you don’t choose, we will have to do C as you cannot have this amount of stuff around your bed. Your stuff will still be safe and you can choose a bag’s worth to keep with you plus your dolls”.
Choice C would be something like social services arranging storage of the items. I imagine this is the ‘tough love’ talked about earlier (at least, I hope so).
