The Australian Digital Health Agency (ADHA) has revealed roughly 900,000 people have opted out of My Health Record as of the 12th of September.

ADHA head Tim Kelsey says the estimate is not comprehensive and reflected only opt outs via the website and call centres, as paper forms have not yet been reconciled.

A variety of health and privacy advocate groups have criticised My Health Record, due to concerns about patient privacy, the system’s security, and access by third parties such as law enforcement.
