Patients across NSW are spending less time waiting in emergency departments, and the state is on track for a multi-million dollar reward for the improved performance.
However, some hospitals, including in western Sydney, are still struggling to see half of the people who front emergency departments leave within four hours.
The Bureau of Health Information released its Hospital Quarterly Report on Wednesday, detailing improvements in surgical and emergency department waiting times across the board.
Between July and September, 65 per cent of people in emergency departments were seen within four hours, a seven per cent improvement but still short of the 71 per cent 2013 national efficiency benchmark.
The National Emergency Access Target (NEAT) measures the ratio of patients who leave emergency departments within four hours.
The waiting times are longer in hospitals such at Bankstown and Blacktown, where 47 per cent and 46 per cent of people respectively left emergency departments in four hours.
However, NSW Health is confident it will achieve this year's NEAT of seeing 71 per cent of emergency department presentations in October and November.
NSW will find out early next year whether the monthly results will be enough to claim $31 million in reward funding from the Commonwealth.
"In October we were just above 71 per cent and in the November preliminary data, we are just shy of 73 per cent," NSW Health systems relationship branch director Luke Worth said.
"We started the year as an accumulative average of 65 per cent, so to jump four per cent in an entire year is a massive improvement."
But Health Minister Jillian Skinner said patient care in NSW would not be compromised to meet NEAT.
"What this report shows is that patients in NSW are receiving quality care quicker than ever before," she said on Wednesday.
"The work that has been done on the ground to get us to this point cannot be underestimated.
"Huge improvements have been made and I'm very proud of the innovative work being undertaken at a local level to ensure hospitals are not only meeting patient demand but striving to be better."
Opposition health spokesman Andrew McDonald said while he supported the NEAT, there was a danger in pressuring hospitals to meet targets.
"If the hospital's main drive is to achieve the NEAT benchmark ... everyone then has incredible pressure to get patients out," he told AAP.
Dr McDonald said based on the new quarterly results, half of the state's emergency patients were still on a stretcher after 27 minutes.
The report also shows despite an increase in elective surgery procedures, 97 per cent were completed on schedule in NSW - a four per cent improvement on the previous year.
The opposition highlighted waiting time blow outs for elective surgeries at some individual hospitals.
The waiting time for ear, nose and throat surgery increased from 121 to 302 days at Sutherland Hospital in Sydney's south and 122 to 300 days at Maitland Hospital in the Hunter.
