If they haven't forgotten the elderly while they still come to the hall, then they pretty much ignore them once they are in a nursing home.
This is what I observed with a large number of cases. If they could still make it to a meeting, then if (and only if) some individual witness family or individual would get them to the meetings, they at least were noticed to be at the meetings.
Once it got to the point they couldn't get to the meetings, they were generally forgotten in some nursing home.
I think that the dirty secret was that nobody cared - if they were baptized, then you couldn't count time - so what would be the point?
