That judgement is based on the WA Emergency Access Target (WEAT), which requires 90 per cent of all patients are dealt with within a four-hour window.

Health department reports reveal for the first half of 2019, Joondalup Health Campus was the worst performing ED in trying to meet the time-restricting rule that was imposed on WA hospitals in 2009.
