Highest priority NSW ambulance call-outs have spiked, with unions blaming the blowout on a change to triage questions asked by triple zero operators.
The most urgent of emergencies, classified P1A by the service, increased 72.8 per cent in the second half of this year compared to before the COVID pandemic, according to the Bureau of Health Information (BHI).
NSW Ambulance conducted 330,591 responses in the July to September quarter, of which a record 12,321 were P1As or immediately life-threatening.
