Frailty is independently associated with increased hospitalisation days in patients on the liver transplant waitlist

AIM: To investigate the impact of physical frailty on risk of hospitalisation in cirrhotic patients on the liver transplant waitlist. METHODS: Cirrhotics listed for liver transplantation at a single centre underwent frailty assessments using the Fried Frailty Index, consisting of grip strength, gait speed, exhaustion, weight loss, and physical activity. Clinical and biochemical data including MELD score as collected at the time of assessment. The primary outcome was number of hospitalised days per year; secondary outcomes included incidence of infection. Univariable and multivariable analysis was performed using negative binomial regression to associate baseline parameters including frailty with clinical outcomes and estimated incidence rate ratios (IRR). Incidence of infection was not influenced by frailty. CONCLUSION: In cirrhotics on the liver transplant waitlist, physical frailty is a significant predictor of hospitalisation and total hospitalised days per year, independent of liver disease severity.
