The charity Mencap has called on the Government to show leadership in providing better local services for people with learning difficulties.
Spokesman for Dan Scorer said institutions like Winterbourne View are supposed to provide temporary care.
Instead he said they were becoming a "dumping ground for people with complex needs who local authorities are struggling to support".
Mr Scorer said better local service would prevent people being taken away from their friends and family and help prevent abuse in the future.
