Investigating apparent variation in quality of care: the critical role of clinician engagement.

• This article reports the experience of the Victorian Department of Health in seeking clinician engagement in the testing of 11 quality-of-care indicators in 20 health services in Victoria. • The Department previously developed a suite of 18 core indicators and seven subindicators known as the AusPSI set. • We used routinely collected administrative data from the Victorian Admitted Episodes Dataset to produce variable lifeadjusted display (VLAD) control charts for 11 selected indicators.
