Key result
Intensive care unit readmission was associated with a four-fold greater probability of hospital mortality and a 2.5-fold increase in hospital stay compared to patients without readmission.
Why the study?
What patient characteristics increase the risk for intensive care unit readmission, and is readmission associated with increased mortality and resource use?

Identifies high-risk patients post-ICU; leaves open whether preventing readmission improves survival or requires case-mix adjustment in quality metrics.

What patient characteristics increase the risk for intensive care unit readmission, and is readmission associated with increased mortality and resource use?
Effect estimate: 4-fold greater probability
Intensive care unit readmission is associated with a four-fold increased risk of hospital mortality and significantly longer hospital stays, highlighting the need for careful discharge decision-making and case-mix adjustment when using readmission as a quality measure.
Kramer et al. (2011) conducted a cohort in Intensive care unit admission (n=229,375). Intensive care unit readmission vs. No intensive care unit readmission was evaluated on Hospital mortality (4-fold greater probability). Intensive care unit readmission was associated with a four-fold greater probability of hospital mortality and a 2.5-fold increase in hospital stay compared to patients without readmission.
