A controversial South Australian Government-run nursing home for elderly people with dementia has been sanctioned by the Commonwealth following allegations of mistreatment of residents. The Federal Government has acted on concerns about medication management at the Older Persons Mental Health Service in Adelaide’s north-east. A nursing adviser must be appointed to help bring the facility at Oakden up to standard. Former independent advisers Carla and Neil Baron have blown the whistle on “shocking” failings at the facility, after being brought in as advisers when the facility was last sanctioned in 2008. Mrs Baron said she was haunted by a memory from her time at the facility.
