ARTICLE HIGHLIGHTS
Research Background

Among cirrhotic patients, hepatic encephalopathy (HE) indicates a poor prognosis despite the use of artificial liver and liver transplantation, presenting as frequent hospitalizations and increased mortality rate.

Research motivation

The aim of this study was to determine predictors of early readmission and mid-term mortality in patients with cirrhosis after an episode of HE, which may contribute to early recognition of fragile cirrhotic patients.

Research objectives

To determine predictors of early readmission and mid-term mortality in patients with cirrhosis after an episode of HE to provide theoretical support for the management of cirrhotic patients.

Research methods

This is an observational study, and the total follow-up time was 6 mo. The primary endpoints were the incidence of early readmission (30 d) and mid-term mortality (6 mo). For each subject, demographic, clinical, and laboratory variables were assessed at the time of diagnosis of HE, during hospital stay, at discharge, and during follow-up.

Research results

International normalized ratio (INR) level at discharge predicted early readmission in cirrhotic patients after the resolution of HE and Model for End-stage Liver Disease score at discharge predicted early readmission caused by HE in these patients. Meanwhile, hemoglobin level at discharge predicted early non-readmission in these patients. Finally, artificial liver use during the first hospitalization independently predicted mid-term mortality.

Research conclusions

INR could be applied to identify fragile cirrhotic patients, Model for End-stage Liver Disease score could be used to predict early relapse of HE, and anemia is a potential target for preventing early readmission.

Research perspectives

Further controlled trials are needed to verify the efficacy of these strategies in lowering early readmission rate when surveilling fragile cirrhotic patients. Expect for patients with anemia, how those patients with an elevated INR and MELD score can be prevented from readmission remains a question that needs to be answered in future studies.
