Frailty in Pediatric Liver Disease May Be Associated With an Increased Incidence of Readmissions After Pediatric Liver Transplantation

Abstract

Background: Frailty is a phenotype of cumulative decline leading to decreased physiologic reserve and vulnerability to stressors. Frailty is associated with adverse outcomes after liver transplantation (LT) in adults, but similar data are not available in children. A prospective multicenter study previously determined that frailty is present in 46% of children with end-stage liver disease (ESLD). We utilized this cohort to evaluate the impact of pre-transplant frailty on post-LT outcomes.

Methods: The study included pediatric participants from the original frailty study across 10 North American transplant centers who had subsequently undergone LT. Clinical outcomes were collected up to 1 year post LT. Participants were stratified by their pre-transplant frailty score (defined by a pre-LT frailty score of ≥ 6.0) and long-term outcomes were compared between groups.

Results: 28 (60.7% female, 46.4% biliary atresia) pediatric LT recipients were included, and 54% of children met criteria for frailty (n = 15). Baseline characteristics were comparable between groups; however, those with frailty were significantly more likely to have pre-transplant failure to thrive (33.3% vs. 0%, p = 0.044). Thirty-four hospital readmissions (22 in frail and 12 in non-frail children) occurred in 20 patients. Higher pre-transplant frailty scores were also significantly associated with an increased number of readmissions after transplantation (p = 0.034).

Conclusions: Pediatric frailty may be associated with the adverse outcome of increased frequency of hospitalization in the first year after pediatric liver transplantation. These data support the concept that frail children should be identified and targeted for prehabilitation prior to LT.

Keywords: comprehensive clinical assessment; end‐stage liver disease; functional status; pediatric liver transplant outcomes; prehabilitation.
