Risk Factors for Readmission to ICU Following Cardiac Surgery

Purpose: To identify risk factors for readmission to the intensive care unit (ICU) following cardiac surgery as reported by Litmathe et al.

Description

Litmathe et al identified risk factors for intensive care unit (ICU) readmission for a patient who has undergone cardiac surgery. Aggressive follow-up of a patient with risk factors may reduce the risk of readmission. The authors are from Heinrich-Heine University in Duesseldorf.


Patient selection: patient discharged from the ICU after cardiac surgery

 

About 6% of 3,374 patients were readmitted to the ICU. Readmission is associated with long ICU stays and a relatively high hospital mortality rate.

 

Risk factors for readmission to the ICU:

(1) mechanical ventilation > 24 hours during the initial ICU admission

(2) preoperative renal failure

(3) re-exploration for bleeding

(4) low cardiac output

(5) complex surgery (valve replacement with or without CABG, other)

 

Reasons for ICU readmission:

(1) respiratory failure

(2) cardiovascular instability

(3) renal failure

(4) cardiac tamponade or post-operative bleeding

(5) gastrointestinal complications

(6) sepsis
