Introduction Frailty is a common but often underestimated complication in patients with liver cirrhosis. The Clinical Frailty Scale (CFS) allows the assessment of frailty within a short period of time but has only been investigated in a Canadian cohort of outpatients. The aim of the current study was to evaluate the ability of the CFS to predict mortality in outpatients and nonelectively hospitalized German patients. Methods Two hundred outpatients and 99 nonelectively hospitalized patients with liver cirrhosis were prospectively enrolled. Outpatients/inpatients were followed for a median of 364/28 days regarding the primary outcome of death or liver transplantation. Eighty-seven patients of the outpatient cohort and 64 patients of the inpatient cohort had available computed tomography-scans for the quantification of muscle mass. Results Median CFS was 3 in the outpatient and the inpatient cohort. Twenty-one (10.5%) outpatients were at least prefrail (CFS > 3) and 26 (26.3%) inpatients were frail (CFS > 4). For every one-unit increase, there was an independent association between the CFS and mortality in the outpatient cohort (hazard ratio 1.534, P = 0.007). This association remained significant after controlling for muscle mass in the subcohort with available computed tomography scans. In the inpatient cohort, frailty (CFS > 4) was an independent predictor for 28-day mortality after controlling for acute-on-chronic liver failure, albumin, and infections (odds ratio 4.627, P = 0.045). However, this association did not reach significance in a subcohort after controlling for muscle mass. Discussion Especially in outpatients, CFS is a useful predictor regarding increased mortality independent of the muscle mass.
