Abstract
INTRODUCTION: There is a lack of data on the impact of readmission to the same vs a different hospital following an index hospital discharge in cirrhosis patients. METHODS: We sought to describe rates and predictors of different-hospital readmissions (DHRs) among patients with cirrhosis and also determine the impact on cirrhosis outcomes including all-cause inpatient mortality and hospital costs. Using the national readmissions database, we identified cirrhosis hospitalizations in 2013. Regression analysis was used to determine the predictors of DHRs. A time-to-event analysis was performed to assess the impact on subsequent readmissions and all-cause inpatient mortality. RESULTS: In 2013, there were 109,039 cirrhosis readmissions with 67% of these being same-hospital readmissions and 33% being DHRs (P < 0.001). Two percent of readmitted patients were treated at ≥4 different hospitals. The 30-day readmission rate was 29.1%. Predictors of DHR included Medicaid payer (adjusted odds ratio [OR] 1.07, 95% confidence interval [95% CI] 1.01-1.14), age (OR 0.98, 95% CI 0.978-0.982), elective admission (OR 1.09, 95% CI 1.01-1.17), hepatic encephalopathy (OR 1.20, 95% CI 1.16-1.25), hepatorenal syndrome (OR 1.09, 95% CI 1.03-1.16), and low socioeconomic status (OR 1.15, 95% CI 1.06-1.25). No difference was observed in 30-day readmission risk following a DHR (adjusted hazard ratio 1.044, 95% CI 0.975-1.118). In addition, there was no increased risk of inpatient death observed during a DHR within 30 days (adjusted hazard ratio 1.08, 95% CI 0.94-1.23). However, patients with DHR had significantly higher hospital costs and length of stay. CONCLUSIONS: Majority of cirrhosis readmissions are same-hospital readmissions. Different-hospital readmissions do not increase the risk of 30-day readmissions and inpatient mortality but are associated with higher hospital costs.
