E-health company Pro Medicus has delivered more than one million transactions through its e-health offering, Promedicus.net.
Pro Medicus chief executive officer, Dr Sam Hupert said: "Promedicus.net is now the largest e-health service in Australia."
The Promedicus.net Secure E-mail System is a specialised 'secure hotmail' service that enables referring doctors to receive encrypted patient results via the Internet. It was launched in May 2000.
More than 7000 doctors are registered with the service.
Transaction volumes have been breaking the 100,000 per month barrier and total volumes have now exceeded the one million transactions.
"With this rate of growth we expect to record our two millionth transaction in about half the time it took to notch up the first million," Hupert said.
