Brief summary

This is a single center, 2-arm, patient-randomized study evaluating the feasibility and potential efficacy of the PRIMER intervention in improving physical function and reducing frailty in adult Liver Transplant candidates. The intervention will consist of a patient-tailored prehabilitation program designed to reduce frailty, improve physical function and nutritional status, and optimize pre- and post-transplant outcomes.

Detailed description

The investigator will pilot-test a two-arm, randomized trial of a prehabilitation intervention in 38 pre-liver transplant patients with End Stage Liver Disease (ESLD). The investigator estimates an attrition rate of 20%, resulting n=30 participants; 10 participants in Arm 1 (control arm) and 20 participants in Arm 2 (intervention arm). To be eligible, patients must be waitlisted or Penn-Ready with a MELD-Na less than or equal to 25, English-speaking, able to safely participant in an exercise program, have a smartphone, and be identified as frail. The purpose of this trial is to develop and implement a program of medical optimization, physical activity, and nutrition recommendations specifically tailored to ESLD and designed to reduce frailty, improve physical function, and optimize pre- and post-transplant outcomes.

Interventions

DEVICENokia GO Wearable StepTracker

All participants will be provided with a Nokia GO step tracker to monitor daily step counts. The device is not subject to FDA regulation.

Medication reminders are sent to participants in Arm 2 on a daily basis.

OTHERWeekly Check-in appointment with study team or provider

Virtual meeting or telephone call between participants and study team to assess study involvement, adherence to procedures, and following of medical care recommendations.

Intervention model description

The investigator will conduct a patient-randomized, two-arm pilot study of 38 participants with a predicted attrition rate of 20% resulting in 30 total participants; n=10 in Arm 1 and n=20 in Arm 2. Arm 1 will serve as the control arm and Arm 2 will serve as the intervention arm.

Inclusion criteria

1. Participants must be wait-listed, in transplant evaluation, or Penn Ready with a MELD-Na score less than or equal to 25; 2. Patients must be English speaking and own/use a smartphone and cognitively able to consent; 3. Patient and physician feel that individual can safely participate in an exercise program; 4. Meeting at least one 'at risk' criterion for impaired physical performance, frailty, or malnutrition (by SPPB, abPG-SG, dynamometer measured grip strength), or physical deconditioning as determined by physical therapist, or treating clinician.

Exclusion criteria

1. The patient is unable to provide informed consent; 2. The patient has been hospitalized within the last 30 days; 3. A score of 0-3 points on the SPPB assessment indicating inability to participate in a physical activity program or a score of 12 in the absence of frailty or malnutrition (indicating low risk for poor physical or performance or malnutrition); 4. The patient is at risk for falling as defined by clinician assessment results or if the patient states that he/she has a history of falling (record of a fall(s) in the past 30 days); 5. The patient is already enrolled in a financial incentive-based exercise program using a wearable device; 6. Any other medical conditions that would prohibit participation in a physical activity program as determined by transplant clinicians or severe vision, hearing, or mobility impairment precluding participation.

Design outcomes

Primary

MeasureTime frameDescription
Feasibility of the Intervention14 weeksFeasibility of the intervention will be evaluated by the percentage of patients that complete the study intervention.
Acceptability of the Intervention14 weeksAcceptability will be measured using a patient satisfaction questionnaire upon study completion.

Secondary

MeasureTime frameDescription
Performance on the Short Physical Performance Battery (SPPB)14 weeksThe SPPB is a simple test to measure lower extremity function using tasks that mimic daily activities. The SPPB examines three areas of lower extremity function; static balance, gait speed, and getting in and out of a chair. Static balance is measured in units of time (seconds) and patients are timed holding 3 different stances. Gait speed is measured in time (seconds) to walk 4 meters. Chair sits are measured as the time (seconds) it takes to get up and out of a chair 5 times without using one's arms to assist the exercise. Collectively, the three tests are used to generate a total score (0-12) that reflects a patient's frailty (score of 0) or lack of frailty (score of 12).
Grip strength14 weeksGrip strength will be measured using a digital hand dynamometer and the unit of measure is kilograms.
Grip strength level relative to BMI14 weeksBody Mass Index (BMI) will be calculated using height in inches and weight in pounds and reported as 'kg/m\^2'. Grip strength will be compared to BMI and a 'BMI-adjusted' grip strength level will be reported using established 'kilogram to BMI ratio' standards.
Body composition/BIA14 weeksBioelectrical impedance analysis will be completed using the Bodystat Quadscan 4000, which is a multi-frequency body composition analyzer. Body fat percentage (%) will be compared to lean body mass percentage and total body water percentage to assess sarcopenia and nutritional status.
