Western Australian Audit of Surgical Mortality (WAASM)

What is WAASM?

The Western Australian Audit of Surgical Mortality is an external, independent and confidential peer review surgical audit.

The audit is centred on evidence based methodology adapted from the Scottish Audit of Surgical Mortality (external site).

WAASM commenced in 2001, and is funded by the WA Department of Health while being managed by the Royal Australasian College of Surgeons (RACS) (external site).

WAASM is designed to provide feedback by surgeons to surgeons. The purpose of this feedback is to inform, educate, facilitate change and improve practice of all clinicians.

The WAASM process

The WAASM methodology flowchart (PDF 18.20KB) gives a diagrammatic representation of the following process:

  • deaths where a surgeon was involved in the care of the patient that occur in public hospitals are automatically notified to WAASM through:
    • electronic patient administration systems (TOPAS or WebPAS)
    • directly by the medical records departments of regional and private hospitals.
  • the consultant surgeon is sent a proforma for completion, highlighting any areas for consideration or concern or adverse events that may have occurred.
  • the completed proforma is anonymised and then given to another consultant surgeon (first-line assessor) for peer review.
  • if the case warrants an additional detailed review it may then be referred to a second-line assessor for case note review.
  • feedback is disseminated to all surgeons, hospitals and the public via WAASM annual reports and other formats.
  • the process is currently protected by:

WAASM annual reports
