The case was first revealed by InDaily last year after the man was rushed to hospital from the Transition to Home (T2H) care service run by the Department of Human Services at Hampstead Rehabilitation Centre.

Paramedics and doctors were so concerned about his condition they lodged complaints about his alleged neglect.

In a report released yesterday following an investigation, Health and Community Services Complaints Commissioner Grant Davies revealed that the man had an infected pressure wound, appeared to be malnourished and was left to sit in faeces and urine for long periods.

Davies made a series of recommendations to improve care for other vulnerable South Australians and demanded authorities apologise to the man and his family.

T2H is a step-down facility for people with disabilities who have been discharged from a long stay in hospital and are awaiting more permanent accommodation.

Responding to the report yesterday, Marshall said there was “no doubt that we have let this patient down and we apologise for that”.

“I unreservedly apologise to this patient and his family,” he told reporters.

“We have fallen well short of the standard which is acceptable and we will take action to ensure this never happens again.”

Marshall said the Government would implement “every single one” of the Commissioner’s recommendations.

“And if there’s need for overall system change then that will be put into place,” he said.

“There are already things identified in this report which I think will lead to improved outcomes for all patients that are in that transitional accommodation.”
