  1. Time components of total ED length of stay are presented as median (IQR) and categorical data are presented as frequency (%). The ED LOS of each subgroup of the total population is shown
  2. In total, 796 (56%) patients had diagnostic tests of which 193 (24%) patients had advanced triage, known as starting diagnostic testing before entering the ED room. In 116 patients, the median time between starting of the blood analysis and entering ED room was 23 min (IQR 9–54). Likewise, urine analysis started in 8 patients and radiology imaging started in 78 patients before entering ED room. The median times and IQR were respectively, 12 min (2–22) and 20 min (11–40). The urine analysis was not finished in 9 patients before admission and the blood analysis was not finished in 68 patients before admission. In these patients the times between finishing diagnostic testing and ED discharge were negative
