NSW's hospitals are the busiest in the country when it comes to emergency departments and elective surgeries.
More than 714,100 people presented to NSW's emergency departments from January to March, the Bureau of Health Information's latest quarterly data reveals.
That means an increase of 1.6 per cent over the same period last year.
During the same period 52,717 elective surgeries were performed in the state's hospitals, an increase of 1.7 per cent.
Western Sydney hospitals are facing record demand but performing well, NSW Health deputy secretary Susan Pearce said in a statement on Wednesday.
