The closure of Hughes Health & Rehabilitation in West Hartford is partly due to a shift to home and community-based services, its owner said. Over the last few weeks, as he waited for the state Department of Social Services to approve his application to close Hughes, he and his staff have been helping the residents still there find new homes. The building’s closure is in part a consequence of a statewide shift to home and community-based services, Flaxman has said, and in part due to declining occupancy and swelling costs.
