Hypothesis
What are the incidence, outcomes, and risk factors for readmission to the surgical intensive care unit?
Conclusion
Readmission to the ICU was associated with a more than five-fold increase in hospital mortality.
Supporting Evidence
- The readmission rate was 13.4%, with 381 patients readmitted.
- In-hospital mortality was significantly higher in readmitted patients (17.1% vs 2.9%).
- Older age and higher SOFAmax scores were associated with a higher risk of readmission.
Takeaway
Some patients who leave the ICU have to come back, and this can be very dangerous for them. Older patients and those with certain health issues are more likely to return.
Methodology
Analysis of prospectively collected data from all patients admitted to the postoperative ICU between September 2004 and July 2006.
Potential Biases
Unmeasured variables may have influenced the results.
Limitations
The study's observational nature limits the ability to determine if readmissions were appropriate.
Participant Demographics
Of 2852 patients, 1828 were male (64.1%), with a mean age of 62 years.
