A history of SA's troubled Oakden home

THE HISTORY OF ADELAIDE'S FAILED OAKDEN NURSING HOME:

* In 2014 first reports of the excessive use of restraints emerge at the state-run home in Adelaide's northeast.

* In 2016 a formal complaint is made to the health department after the death of Bob Spriggs whose family said he was over-medicated and suffered bruising as a result of restraints.

* A report by the state's chief psychiatrist in 2017 finds rough handling of elderly dementia patients, excessive use of restraints and a high level of injuries.

* In May 2017 the ICAC investigation is launched focusing on possible maladministration by senior staff, public servants and ministers.

* The final two patients are moved from Oakden in September 2017 and the home closed.

* In February 2018 a separate Senate inquiry releases an interim report which finds it deeply concerning that warning signs such as unexplained bruising, medication mismanagement and falls were not investigated promptly.

* In his report on February 28, Independent Commissioner Against Corruption Bruce Lander clears former health minister Jack Snelling and former mental health minister Leesa Vlahos of maladministration.

* Mr Lander finds the conduct of five people amounted to maladministration including four former Oakden staff and one health department official.
