One in 10 don't have My Health Record

Almost one-in-10 Australians using Medicare services have decided they do not want an electronic medical record.

By the time the formal opt-out period for the My Health Record system ended in January, 2.5 million Australians had chosen not to be part of it.

Australian Digital Health Agency chief executive Tim Kelsey confirmed the figures at a Senate estimates hearing in Canberra, noting the authority has met its target of 90 per cent participation.
