Millions of Australians use the private health system every year. They should receive safe, high-quality, value-based care. However, poor policy and inadequate regulation of medical technology is driving low-value care at great expense to consumers and the broader health system. Key drivers include the Prescribed List of Medical Devices and Human Tissue, gaps in quality and safety controls for devices being used, and marketing and conflicts of interest. All of these should be addressed to reduce low-value care in Australia's private health system, so consumers are protected from harm and limited health budgets are used effectively.
