“…Frailty is an increased state of vulnerability due to a decline in function across multiple physiologic systems ( Exterkate et al, 2016 ; Watford et al, 2021 ). Among solid organ transplant (SOT) patients, frailty is an important clinical marker associated with increased risk of waitlist death/delisting, post-transplant mortality in kidney, heart, and lung transplant recipients ( Montgomery et al, 2020 ; Varughese at al., 2020 , 2021 ), and increased risk of graft dysfunction and delirium in kidney transplant recipients ( Harhay et al, 2020 ). The most common measure of physical frailty is the Fried Frailty Index (FFI) ( Fried et al, 2001 ), which includes five domains: muscle weakness, low physical activity, weight loss, slowness, and exhaustion ( Kobashigawa et al, 2019 ).…”
