Care of the elderly

Today I found out a different way of looking after the elderly.
It consists of a group of detached and terraced houses and nice bungalows, in a private area where the elderly can live keeping their independence but they also get medical care.
Daily, the person in charge takes care of elderly residents by visiting or calling their homes at least once. The elderly also have a way to ask for assistance, if they need it, they can pull a red chord which is in each room, then a person will come to help them as quickly as possible.
I think, its a good way to take care of the elderly.
