Abstract:
We would like to congratulate Mumtaz et al.1 for their important study attempting to develop and validate a risk score to predict 30-day hospital readmission in decompensated cirrhosis patients using the US nationwide readmission database (NRD). The identification of cirrhosis patients at high-risk for readmission is critical for developing processes to effectively address this problem. However, flaws in patient identification challenge the utility of the risk-score outlined in this study. This article is protected by copyright. All rights reserved.
