The NSW Labor Opposition says the latest revelations of more problems at the trouble-plagued Northern Beaches Hospital are deeply disturbing and demonstrate the importance of a Parliamentary inquiry to shed light on the ongoing failures at the new facility.

A submission by a Dee Why GP to the Parliamentary inquiry reveals how extremely confidential patient records relating to their discharge from the hospital were sent to the wrong doctors.

Hundreds of confidential patient discharge papers were mistakenly sent by Sydney's new Northern Beaches Hospital to the wrong doctors, according to a local GP.

Critically important information including whether the patient had experienced a heart attack were missing from discharge papers, reveals Dr Elana Roseth in her submission to the inquiry that is currently under way into the hospital.

Shadow Health Minister Ryan Park said: “It’s quite clear that the Berejiklian Liberal Government has failed the community with its obsession for privatising the state’s hospitals. As a result it is patients and other medical professionals who are suffering.

“This latest debacle comes on top of key staff leaving the hospital and an endless list of harrowing stories from both doctors and patients undergoing treatment at the hospital.

“The Government and Health Minister Brad Hazzard have tried to put it down to a few teething issues but every new revelation by patients and medical professionals exposes that to be nothing more than a big lie. Patients and health professionals feel incredibly let down.”

Labor pushed for the inquiry because the Auditor-General cannot examine the performance or operations of the $600 million hospital as it are a public-private partnership.
