The Victorian Cardiac Outcomes Registry is a clinical cardiac registry that commenced data collection in 2013, providing a detailed description of selected aspects of contemporary cardiology clinical practice in a majority of Victorian hospitals. This information enables hospitals and cardiac units to benchmark their practice, clinical outcomes and quality of care to other similar units and hospitals across the state. If replicated by other states in Australia, there will be the potential for important national comparisons, with the goal to foster continuous improvement in patient care and outcomes across the entire Australian health system.
