Clinical Trial Summary
The purpose of this study is to test a home-based exergaming intervention designed to
decrease frailty and fatigue and improve affective well-being, functional capacity, and
immune function in individuals with advanced heart failure (HF) and multiple chronic
conditions (MCC) prior to receiving either a left ventricular assist device (LVAD) or
orthotopic heart transplantation (OHT). Prior to surgery, individuals with advanced HF/MCC
experience a high symptom burden that often precludes them from participating in meaningful
physical activity. Pre-surgical fitness programs have been used in other critically ill
populations to improve function prior to surgery. Interactive gaming systems have been
successfully used to engage other seriously ill adults in low-intensity physical activity.
However, exergaming interventions have not yet been applied in individuals with advanced
HF/MCC as prehabilitation prior to LVAD implantation or OHT. The investigators propose that a
prehabilitation exergaming intervention will not only enhance pre-surgical outcomes but will
also augment postoperative outcomes. This study is designed in two-phases. Phase 1 examines
intervention feasibility and phase 2 is a pilot study with a two-group design. In phase 2,
participants will be randomized to a usual care group or the exergaming intervention group.
The exergaming group will participate in a low-intensity exergaming intervention and
additional investigator-developed educational modules that will be delivered via the Nintendo
Wii U exergaming system. The investigators will evaluate pre- and post-surgical frailty,
fatigue, affective well-being, and immune function as primary outcomes. The investigators
expect that participation in low intensity exergaming will improve these primary outcomes
pre- and post-surgically, and decrease post-surgical complications and health care
utilization. Investigator-developed modules will promote self-efficacy, self-regulation, and
activation. This is the first study to apply low-intensity exergaming to a pre-operative
advanced HF/MCC population. The successful application of this intervention has significant
implications to the pre-operative conditioning of individuals with advanced HF/MCC prior to
LVAD implantation or OHT.
Description:
Specific Aims. The objectives of this study are two-fold: (1) To test the feasibility of a
low intensity, home-based exergaming intervention in individuals with advanced HF/MCC prior
to left ventricular assist device (LVAD) implantation or orthotopic heart transplantation
(OHT), and (2) To examine the effectiveness of delivering a low intensity, home-based
exergaming intervention to decrease frailty and fatigue and improve affective well-being,
functional capacity, and immune function in individuals with advanced HF/MCC prior to
receiving an LVAD or OHT.
Other surgical populations who were deconditioned, fatigued, and frail before surgery have
benefited from the use of pre-surgical fitness interventions (prehabilitation).3-5 Innovative
interventions strategies, like the Nintendo Wii Fit exergaming system, have been successful
at engaging seriously ill adults in low-intensity physical activity6,7. However, exergaming
interventions have not yet been applied in individuals with advanced HF as prehabilitation
prior to LVAD implantation or OHT. The investigators propose that a home-based,
prehabilitation exergaming intervention will not only enhance pre-surgical outcomes but will
also augment postoperative outcomes.
The investigators will conduct this study in two phases. Phase 1 is designed as a feasibility
study in a smaller sample (5 participants and 5 informal caregivers) to allow initial
evaluation of the intervention including troubleshooting the technological components and
evaluating study recruitment, retention, and intervention safety prior to initiating the
larger, two-group randomized study. Phase 2 will enroll a convenience sample of 40
participants with advanced HF/MCC who are being evaluated for LVAD implantation or OHT at
Nebraska Medicine and their 40 informal caregivers for a total sample of 80 enrollees (n=40
exergaming, n=40 usual care).
In both phases, the exergaming group will participate in a low-intensity exergaming
intervention and additional investigator-developed educational modules (e.g. symptoms while
exercising, exercising with heart failure) that will be delivered via the Nintendo Wii U
exergaming system. Investigator-developed modules are designed to promote self-efficacy,
self-regulation, and activation. Individuals with advanced HF/MCC will be expected to
participate in the exergaming intervention and the investigator-developed modules. Caregivers
will be asked to be present for all training sessions and participate in the
investigator-developed modules. The investigators will evaluate pre- and post-surgical
frailty, fatigue, affective well-being, and immune function as primary outcomes in the
individuals with advanced HF/MCC. The investigators expect that participation in low
intensity exergaming will improve these primary outcomes pre- and post-surgically, and
decrease post-surgical complications and health care utilization. Relationships will be
examined among self-efficacy, self-regulation, and activation scores over time, and adherence
to the intervention to test whether self-management mechanisms were effective in promoting
adherence. Additionally, post-intervention qualitative interviews will be conducted to assess
participant and caregiver experiences with the intervention.
Specific aims of this study are the following:
Aim 1 (Phase 1): Evaluate the feasibility of the home-based, low intensity exergaming
intervention in individuals with advanced HF/MCC prior to LVAD implantation or OHT and their
informal caregivers by assessing recruitment, enrollment, acceptability, adherence, subjects
perception of barriers and facilitators, and implementation (delivery, fidelity, and
procedures for data collection).
Aim 2 (Phase 2): Evaluate the impact of home-based, low intensity exergaming on pre- and
post-surgical outcomes: frailty, fatigue, affective well-being, immune function, and
biomarkers of co-morbid conditions at baseline, 4 weeks, and 1 and 3 months post-surgery
compared to usual care (All subjects with advanced HF/MCC).
H1. Subjects in the exergaming group will have decreased frailty and fatigue and improved
affective well-being and immune function compared to usual care.
Aim 3 (Phase 2): Evaluate the impact of home-based, low intensity exergaming on post-surgical
complications (death, infection, bleeding, and rejection) and health care utilization
(emergency department visits, unplanned hospital admissions) compared to usual care (both
groups of subjects).
H2.a. Subjects in the exergaming group will have fewer post-surgical complications compared
to usual care.
H2.b. Subjects in the exergaming group will have fewer emergency department visits and
hospital admissions compared to usual care.
Aim 4 (Phase 2): Explore relationships among self-efficacy, self-regulation, and activation
scores over time, intervention adherence, and pre- and post-surgical outcomes (Exergaming
group participants and caregivers only).
There is a critical need to address deconditioning, fatigue, and frailty in individuals with
advanced HF/MCC prior to LVAD implantation or OHT. This innovative exergaming intervention
incorporates the use of an interactive, home-based technology to improve pre-and
post-surgical outcomes
