Frailty predicts waitlist mortality in liver transplant candidates

Area of Science:

• Geriatrics
• Transplantation Medicine
• Clinical Outcomes Research

Background:

• Frailty is a recognized geriatric syndrome indicating increased vulnerability to stressors.
• Its predictive value for mortality in liver transplant candidates requires further investigation.
• Liver transplant candidates often present with complex health conditions impacting outcomes.

Purpose of the Study:

• To assess the association between frailty and waitlist mortality in liver transplant candidates.
• To determine if frailty predicts mortality independently of liver disease severity (MELD score).
• To evaluate the prevalence of frailty using multiple validated instruments in this population.

Main Methods:

• A prospective study of 294 adult liver transplant candidates with MELD score ≥12.
• Four frailty assessments were performed: Fried Frailty, SPPB, ADL, and IADL scales.
• Competing risks models were used to analyze the association between frailty and waitlist mortality (death or delisting).

Main Results:

• 17% of patients were identified as frail using the Fried Frailty criteria.
• Frail patients had a significantly higher rate of waitlist mortality (22% vs. 10%, p=0.03).
• Increased Fried Frailty score and decreased SPPB score were independently associated with higher waitlist mortality risk, even after MELD adjustment.

Conclusions:

• Frailty is prevalent and a strong independent predictor of waitlist mortality in liver transplant candidates.
• Incorporating frailty assessments can enhance risk stratification for patients awaiting liver transplantation.
• The findings underscore the clinical relevance of the frailty construct in managing end-stage liver disease.
