Hypothesis
The LODS might have good predictive power for risk of mortality in cardiac surgical patients.
Conclusion
The LODS showed reasonable accuracy in predicting ICU mortality in patients after cardiac surgery.
Supporting Evidence
- The study included 2801 patients with a 5.2% ICU mortality rate.
- The LODS had a good calibration with no significant difference between expected and observed mortality rates.
- The highest accuracy of LODS was observed on ICU day 3.
Takeaway
The LODS is a tool that helps doctors predict if heart surgery patients might have serious problems after their operation.
Methodology
This prospective study included all consecutive adult patients admitted to the ICU after cardiac surgery between January 2007 and December 2008, with daily LODS calculations.
Potential Biases
The LODS may overestimate mortality risk in low-risk patients due to temporary effects of surgery.
Limitations
The study focused only on ICU mortality rather than in-hospital or longer-term mortality.
Participant Demographics
The mean age was 66.4 years, with 29.6% female participants.
