Post-operative/ morbidity/ mortality indicators
Post-operative ICU LOS by procedure type In 2021, the median LOS in the ICU post-operatively for all cardiac surgery cases was three days (IQR: 2–4 days) (Figure 12).
Mortality
Table 9 details each mortality type by clinical status and procedure types. The values are expressed as frequencies and percentages, with percentages calculated by dividing the number of mortalities by the number of cases in each procedure type (n) .
