A report released late last year by the Auditor General found that during 2009, Liverpool Hospital's surgery waiting list increased by 450 patients from 1851 to 2301.

Ms Skinner said the figures showed Labor's health policies had failed Liverpool residents.

``There are more patients waiting for surgery in NSW than ever before and it is because the incompetent State Labor Government has failed miserably to deliver for families, patients and frontline health workers,'' she said.

She said local Labor MPs Alison Megarrity, Andrew McDonald, Diane Beamer and Paul Lynch were part of the problem, because they had focused on Labor's factional fighting instead of fixing the health system.

Dr McDonald, Macquarie Fields MP and an acting clinician at the hospital one day a week teaching medicine students and seeing patients, said he saw a lot more of the hospital system than Ms Skinner did.

``The NSW health system has never been under greater pressure, so as a consequence the waiting lists are long,'' he said.

``We try to treat everybody based on the priority of waiting lists, based on the fact we are all living 14 years longer and medical technology means we are able to do so much more than we used to.

``While John Howard took a billion dollars a year out of the hospital system, Jillian sat as mute as a Buddhist statue. What the people of the electorate want to know is what the Liberal Party are actually going to do.''

The hospital's general manager, Glenda Cleaver, said hospital staff were working diligently to treat the majority of major elective surgery patients within benchmark times.

``Emergency surgery accounts for almost 50per cent of overall surgery performed at the hospital,'' she said.

``The average wait for patients requiring surgery within the 90-day benchmark was only 50 days.''
