Primary ICT LOS (hours) 26.9 [23.2; 46.0] 41.1 [24.8; 60.2] 0.02
PACU + ICU + IMC excl. readmission
Total ICT LOS (hours) 30.9 [23.9; 59.9] 43.9 [24.9; 65.4] 0.08

  1. Total ICT LOS = total intensive care treatment (ICU + IMC + PACU) length of stay including readmissions from step-down unit to unit of higher grade (reintubation time was calculated only for patients who were reintubated). PACU, post-anaesthetic care unit; ICU, intensive care unit; LOS, length of stay; IMC, intermediate care unit.
