Exercise-based Frailty Intervention in Lung Transplantation (XFIT)

We will randomize 70 patients who reflect the diversity and spectrum of illness seen in the general lung transplant candidate population to either XFIT or enhanced standard of care. An interventionalist with expertise in exercise physiology and remote interventions will deliver 8 weekly sessions using video-conference software in participants' homes. These sessions feature one-on-one exercise training and targeting of behavioral barriers to optimizing physical activity using motivational interviewing principles. Establishing safety is our primary outcome. We will secondarily establish feasibility and acceptability, and explore responsiveness six-minute walk distance, frailty, Patient Reported Outcomes . We anticipate that this first-of-its kind study in solid organ transplantation will establish fundamental safety, feasibility, and accessibility data needed inform larger scale interventions.
