WAASM commenced on 1 June 2001 as a pilot project, under the management of the University of Western Australia.
In 2005 management of the project was transferred to the College. The WAASM Management Committee oversees the project which constitutes an invaluable foundation to the running and success of the audit program.
The project is funded by the Western Australian Department of Health (WADH).
In November 2006, the WADH issued an operational directive stating that all deaths that occur in public hospitals and licensed private health care facilities providing services for public patients are required to be classified and reviewed under the Western Australian Review of Mortality (WARM). WARM came into effect on 1 January 2007. Deaths that are reviewed under the WAASM process are exempt from the WARM process.
