Doctors in the Hunter region are reporting major flaws in the Federal Government's E-health system that was set up to improve patient treatment.
The Hunter Valley is one of three regions in Australia to pilot the program that links a patient's medical records between doctors, hospitals and other providers.
Trials are also running in Brisbane and Melbourne.
Newcastle's King Street Group Practice is one of several GP services struggling with the new system.
The group's Doctor Peter Hopkins says one of the major failures is keeping a patient's medical information updated.
"It doesn't change unless someone re-enters (the information) and puts in a new page, so it's not something that can easily be altered in someone who changes their medications or other health issues develop unless the page is updated, it still has the old information on and that's what we access," he said.
"The amount of work that's going to be needed to keep that up to date is tremendous."
Many Newcastle GPs say the system is adding to stress levels and making their workloads excessive.
They are complaining the E-health program unworkable in its present form and is increasing their workload by up to two hours a day.
Doctor Hopkins says doctors in his group practice support the initiative, but feel it is an unfair burden.
"It's actually how many patients the GPs have enrolled in their own practice and I haven't enrolled anyone yet.
"Doctor Barnett who is our main computer doctor has tried to do it for some patients and the time it's taking to do it and the hurdles he's had to jump over when he's tried to implement it and the feedback we're getting from him hasn't been positive."
