Comparison of Frailty Trajectories in Lung Transplantation

Purpose: Two conceptual models of frailty, physical/frailty phenotype and cumulative deficits/frailty index, have both been associated with lung transplant outcomes. We aimed to compare the trajectories of physical and cumulative deficits frailty before and after lung transplantation (LTx). While physical frailty has been shown to improve post-LTx, we hypothesized that cumulative deficits would not improve as new deficits accrue after LTx.
