To the Editor: Recent media reports imply there is an increased pressure on Adelaide’s metropolitan emergency medical system which has resulted in additional ambulance ramping and consequent industrial action.1,2,3 We collected a novel dataset of emergency department (ED) capacity state observations at 30‐minute intervals from the public South Australia ED Dashboard4 to investigate the claims of increased pressure. The dashboard uses a traffic light system to indicate ED busyness.
