Integrated South Australian Activity Collection (ISAAC)

The Integrated South Australian Activity Collection (ISAAC) contains state-wide data capturing information about patients separated from public and private hospitals.

It provides SA Health with the information resources necessary to effectively fund, organise, evaluate, and plan health services in South Australia.

ISAAC data also allows SA Health to meet national obligations through annual submissions to the Australian Institute of Health and Welfare (AIHW). ISAAC forms part of the Admitted Patient Care National Minimum Data Set through submission to AIHW.

For more information on ISAAC please contact the Information Assembly Unit on (08) 8226 7321 or refer to the ISAAC Reference Manual.
