Wollongong Hospital has continued to improve on the number of patients leaving the emergency department within four hours of arrival, according to new data.
Bureau of Health Information statistics for October to December 2013 show 64 per cent of the 15,199 patients who presented to the ED left within four hours.
While still below the state average of 70 per cent, it was a significant improvement on the 49 per cent in the same period in 2012.
Illawarra Shoalhaven Local Health District's acting director clinical operations Suzanne Harris said the hospital was always working on ways to improve treatment times and address increases in demand.
"An example of this is the implementation of a minor injuries and illness unit within the ED at Wollongong," she said.
"This allows less urgent presentations to been seen more quickly, reducing wait times and improving access for those with minor illness."
At Shellharbour Hospital, 61 per cent of the 7196 patients left within four hours, while at Bulli Hospital (1595 patients) the rate was 99 per cent.
The average time for seriously ill patients - known as triage two - to begin treatment was 10 minutes at Wollongong Hospital, two minutes below the NSW median.
