Intensive care unit (ICU) readmission after cardiac surgery is believed to be associated with higher in-hospital mortality and may predict poor outcomes. ICU readmissions use resources and increase treatment costs. ⋯ The most common cause of readmission to ICU is haemodynamic instability. Postoperative complication and in-hospital mortality rates are significantly higher in patients readmitted to ICU. Factors most commonly predisposing to readmission to ICU after cardiac surgery included advanced patient age, non-elective surgery, and longer initial stay in ICU after the surgery.
