BACKGROUND: Frailty is prevalent in end-stage liver disease and predicts higher waitlist and posttransplant mortality. Despite association of frailty with poor clinical outcomes, evidence-based interventions to reverse frailty remain scarce.
METHODS: In this pilot study, we tested the feasibility of a novel home-based frailty intervention using home exercise equipment, a smartphone application, and remote frailty assessments to create a dynamic and personalized exercise program for patients with cirrhosis evaluated for liver transplantation.
RESULTS: Fifty-four patients (mean 57.2 [±9.9] y, 59% men) enrolled in the study, with a mean Model for End-Stage Liver Disease-Na 16.9 (±5.8; 70% decompensated). The mean baseline Liver Frailty Index (LFI) was 3.59 (±0.60). The mean follow-up time was 259 (±190) d and the mean change in LFI at the end of the intervention was -0.11 (3.59 versus 3.48, P = 0.05), representing a clinically meaningful improvement in frailty previously associated with increased survival. In comparison, the retrospective control group, which had similar demographics and clinical characteristics as the intervention group, did not show a significant change in LFI (3.97 versus 3.91, P = 0.57). Fifty-six percent of patients were adherent (fully or partially) to recommended levels of exercise, and adherence rates declined from 1 to 3 mo after enrollment, underscoring the need to maintain patient engagement in exercise.
CONCLUSIONS: This study shows that a home-based frailty intervention is feasible. The intervention led to significant improvement in frailty, which was not seen in the retrospective control group. Future studies, including randomized controlled trials, are necessary to further assess the efficacy of the intervention and also determine its impact on downstream clinical outcomes.
