Association of severity of XXXX and intensive care unit readmission: A systematic review.

@entity1 @entity221
OBJECTIVES: To determine whether ICU readmission is associated with higher severity of @entity221 scores in adult @entity1 . BACKGROUND: Readmissions to the intensive care unit (ICU) are associated with increased costs, morbidity, and mortality. METHODS: We performed searches of MEDLINE, EMBASE, and grey literature databases. We selected studies reporting data from adults who were hospitalized in an ICU, received severity of @entity221 scores, and were discharged from the ICU. Characteristics of readmitted and non-readmitted @entity1 were examined. RESULTS: We screened 4766 publications and included 31 studies in our analysis. In most studies, severity of @entity221 scores were higher in @entity1 readmitted to the ICU. Readmission was also associated with higher mortality and longer ICU and hospital stays. Excessive heterogeneity precluded the reporting of results in the form of a meta-analysis. CONCLUSIONS: ICU readmission is associated with higher severity of @entity221 scores during the same hospitalization in adult @entity1 .
