Abstract
PURPOSE OF REVIEW: Frailty is an emerging concept in liver transplantation. We reviewed the literature for the tests of frailty which have been validated to predict outcomes in patients with cirrhosis evaluated for liver transplantation. RECENT FINDINGS: Several tools have been developed to further stratify risk of adverse events independent of liver disease severity. These include tests of disability such as activities of daily living and the Karnofsky Performance Score as well as tests of physical frailty such as the Liver Frailty Index (hand-grip, chair stands, and balance). SUMMARY: Increasingly, the frailty assessment is seen as a critical component of the liver transplant evaluation. Further research is needed to clarify the optimal timing of testing and the implications of longitudinal change.
