Abstract
Background
The liver-renal-risk (LIRER) score was developed to predict adverse outcomes in cirrhotic patients with Model for End-stage Liver Disease (MELD)<18, helping the allocation to liver transplantation in this population. We aimed to assess its prognostic performance compared to other prognostic scores in first admission for hepatic cirrhosis decompensation.
Methods
Retrospective study that included patients admitted for initial decompensation of cirrhosis between January 2010 and February 2017. The LIRER, Child-Pugh (CP), MELD and MELD-sodium (MELD-Na) scores were calculated at admission.
Results
One-hundred and forty-six patients were included, 65.1% with MELD < 18. LIRER was a predictor of in-stay (AUC 0.70; p = .04), first-year (0.70; p < .001), two-years (0.72; p < .001) and overall mortality (0.70; p < .001), being the only score with an acceptable discriminating ability (AUC ≥ 0.70). Stratifying patients in MELD < 18 and ≥18, LIRER was found to be an independent predictor of first-year, two-years and overall-mortality only in MELD < 18 patients (AUC 0.67; 0.70; 0.72), being superior to all other scores predicting first-year mortality and the only with an AUC with a reasonable discriminating ability for predicting two-years and overall-mortality. The LIRER was also a predictor of 30-days hospital readmission (AUC 0.75; p < .001), independently of MELD, with patients with LIRER > 15.9 having a significantly higher probability to be readmitted at 30 days.
Conclusions
The LIRER score is a predictor of first-year, two-years and overall-mortality in decompensated cirrhosis, particularly in patients with MELD < 18. LIRER is therefore an important tool to predict medium-long-term outcomes in this population. Besides, it allows predicting the 30-days readmission probability in overall patients, independently of MELD.
