A NSW parliamentary committee had called on NSW Health to finalise an upgrade to the state's Incident Information Management System (IIMS) “as a matter of urgency” after hearing there were flaws in the system that meant the full implementation has been delayed.

NSW Health officials also blamed the 2017 purchase of Melbourne-based RiskMan International – which won the tender in 2015 to replace the existing AIMS-based incident management system – by UK firm Datix as another reason behind the delay.
