Carer fired after cerebral palsy sufferer's 'disgusting' death

The carer responsible for looking after cerebral palsy sufferer Ann Marie Smith when she died has had her employment terminated.

Her employer, Integrity Care SA, said it was "shocked and appalled" by Ms Smith's case, which has left disability advocates calling for more safeguards.

Ms Smith, 54, died in the Royal Adelaide Hospital on April 6 from septic shock and multiple organ failures from severe pressure sores, and was also malnourished.

Police allege Ms Smith had been confined to a single chair in her home for 12 months or more, despite having a carer.

Detective Superintendent Des Bray claimed Ms Smith had died in "disgusting and degrading" circumstances.

The home of Ms Smith's carer has since been raided by detectives, and Integrity Care SA is being scrutinised by the industry watchdog.

The company insisted all other clients within that carer's purview were in good health, and that it had been "misled" by the carer.

However, the NDIS Quality and Safeguards Commission has accused Integrity Care SA of "failing to take all reasonable steps to prevent and respond to all forms of violence against, and exploitation, neglect and abuse of, people with disability".

Calls for systemic change following Ms Smith's death include a push to expand the community visit scheme, which allows volunteers to perform spot checks on people in care.

State Human Services Minister Michelle Lensink, however, said the scheme had never allowed volunteers to visit private homes.

Nobody has been charged over Ms Smith's death.
