The survey, which applied to English and Welsh councils only, found that 106,000 elderly people and physically disabled children and adults were comprehensively assessed by social services staff between May and July this year, to help them decide whether they should be cared for in the community or in a residential or nursing home.
It found that 21,308 of those assessed decided to go into some form of institutional care, with 80% of them in non council-run homes. The remainder chose to live in their own homes with varying degrees of social services support.
The survey also showed that 46% of users entering an establishment went to a residential home, while 54% were admitted to a nursing home. And for every five comprehensive assessments made, one social services user opted for residential care.
He also stressed the importance of monitoring and regularly inspecting residential homes.
