Readmission following liver transplantation: an unwanted occurrence but an opportunity to act

Background Liver transplant (LT) patients are at high risk for readmission. This study sought to identify predictors of readmission following liver transplantation and to evaluate their impact on survival in a region with prolonged waiting list times. Methods A single center review of adult deceased donor LT's from 2005 to 2015 was performed, with linkage to the UNOS Standard Transplant Analysis and Research registry. Readmission was defined as hospitalization within 90 days of discharge. Logistic regression was used to identify independent predictors of readmission and Kaplan–Meier analysis for survival. Results 325 patients underwent LT with an overall 90-day readmission rate of 46%. Upon adjusted analysis, predictors of readmission were age (OR 0.97 per year), male gender (OR 0.48), hospital length of stay (OR 1.03 per day), and hepatitis C liver failure (OR 2.37). Readmitted patients demonstrated a significantly lower 5-year survival (75% vs. 88%, p = 0.008) with only one patient (0.7%) dying during initial readmission. Conclusions Nearly half of all patients are readmitted after LT. As readmission portents decreased survival, an emphasis should be placed on identifying and optimizing those at increased risk. If readmission does occur, however, it presents an opportunity to intervene, as virtually no patients died during initial readmission.
