Insights
Intensive care unit (ICU) readmission after coronary artery bypass grafting (CABG) occurs in 3.5% of patients, significantly increasing 90-day mortality. Identifying risk factors like respiratory and cardiac complications is crucial for better patient outcomes.
Area of Science:
- Cardiovascular Surgery
- Critical Care Medicine
- Health Services Research
Background:
- Coronary artery bypass grafting (CABG) is a common cardiac surgery procedure.
- Intensive care unit (ICU) readmission after initial recovery can indicate underlying patient vulnerability or care gaps.
Purpose of the Study:
- To determine the incidence, causes, and predictors of ICU readmission following CABG surgery.
- To assess the impact of ICU readmission on patient mortality after CABG.
Main Methods:
- Retrospective analysis of 4112 patients undergoing on-pump CABG from January 2007 to January 2017.
- Comparison of demographic and perioperative characteristics between patients with and without ICU readmission.
Main Results:
- The ICU readmission rate was 3.5%, with respiratory (29%) and cardiac (23.4%) complications being the primary causes.
- ICU readmission was strongly associated with increased 90-day mortality (22.1% vs. 1.6%).
- Predictive factors included severe left ventricular dysfunction, COPD, ESRD, emergency CABG, high EuroSCORE II, prolonged cross-clamp time, and various postoperative complications.
Conclusions:
- ICU readmission post-CABG is a significant marker for increased mortality risk.
- Comprehensive evaluation of comorbidities, intraoperative factors, and postoperative complications is essential for identifying at-risk patients.
Objective:
To evaluate the frequency, causes, and related predictive factors of intensive care unit (ICU) readmissions after coronary artery bypass grafting (CABG) surgery.
Methods:
A total of 4112 consecutive patients who underwent on-pump CABG between January 2007 and January 2017 were retrospectively evaluated. The patients were divided into two groups as patients with and without ICU readmission. Demographic and perioperative characteristics were compared between the two groups.
Results:
The ICU readmission rate was 3.5%. The most common reasons for ICU readmissions were respiratory (29%) and cardiac (23.4%) complications. The 90-day mortality risk was significantly higher in the readmitted patients than the non-readmitted patients (22.1% and 1.6%, respectively; P<0.001; OR=17.6; 95% CI=11.19-28.41). Severe left ventricular dysfunction, chronic obstructive pulmonary disease, end-stage renal disease, emergency CABG, EuroSCORE II > 5%, cross-clamp time > 35 minutes, postoperative respiratory complications, neurological complications, and cardiac complications showed a strong association with ICU readmissions.
Conclusion:
ICU readmission after CABG is associated with an increased mortality rate. Evaluation, not only of patients' comorbidities, but also of intraoperative conditions and postoperative complications, is important to identify patients at risk for ICU readmission.
