Prognostic Significance of Frailty in Liver Cirrhosis Patients: A Prospective Single-Center Study

TL;DR

This study shows that frailty is a strong predictor of complications and death in liver cirrhosis patients, suggesting it should be used in clinical assessments.

Contribution

The study demonstrates that frailty assessment improves risk prediction beyond traditional liver-specific scores in cirrhosis patients.

Findings

Frailty was significantly linked to higher rates of complications and hospitalizations in cirrhosis patients.

Frail patients had a 22% mortality rate compared to 3.8% in non-frail patients.

Each component of the Fried Frailty Index was independently associated with adverse outcomes.

Abstract

Background: Liver cirrhosis is a systemic disease characterized by progressive hepatic dysfunction and frequent decompensation events. Conventional prognostic models such as the Child–Turcotte–Pugh (CTP) and Model for End-stage Liver Disease (MELD) scores primarily reflect liver-specific severity and may not fully capture the multidimensional vulnerability of patients with cirrhosis. Frailty, a syndrome reflecting reduced physiological reserve, has emerged as a potential prognostic marker in this population. Methods: In this prospective single-center cohort study, 134 patients with liver cirrhosis were enrolled between March and October 2021 and followed at three-month intervals. Frailty was assessed at baseline using the Fried Frailty Index (FFI). Patients were categorized as fit/prefrail or frail. The primary endpoints were cirrhosis-related complications, unplanned hospitalizations, and all-cause mortality. Associations between frailty, its individual components, and clinical outcomes were evaluated. Results: Frailty was present in 41% of patients. Frail patients were older and had higher MELD and CTP scores. During follow-up, frailty was significantly associated with higher rates of ascites (p < 0.001), hepatic encephalopathy (p < 0.001), hepatorenal syndrome (p < 0.001), spontaneous bacterial peritonitis (p = 0.01), and unplanned hospitalizations (p < 0.001). Mortality occurred in 22% of frail patients compared with 3.8% in non-frail patients (p < 0.001). Each frailty component, including reduced grip strength, slow gait speed, low physical activity, exhaustion, and unintentional weight loss, was independently associated with adverse outcomes. Conclusions: Frailty, as assessed by the Fried Frailty Index, is a strong predictor of complications, hospitalization, and mortality in patients with liver cirrhosis. Incorporating frailty assessment into routine clinical practice may improve risk stratification and guide long-term management strategies.
