smartphone delivered in-home cardiopulmonary rehabilitation

Conditions: Cardiovascular Disease; Coronary Artery Disease

Summary: the goal of this study is to determine if a remote cardiac or pulmonary rehabilitation program delivered via a smartphone application and regular telephone calls will lead to improved delivery of cardiac rehabilitation compared to usual care. this includes increased adherence for eligible veterans, increased program completion, improved patient outcomes as measured by functional capacity, improved patient compliance in monitoring symptoms, improved self-efficacy and knowledge in managing disease and, a decreased rate of hospitalization and re-admissions.

this project aims to determine if a smartphone-delivered cardiac rehabilitation (cr) program could show similar clinical outcomes to in-person programs at a low cost in a large population of patients. investigators will also assess the feasibility of tailoring a virtual cr program to a small sample of copd participants who also stand to benefit in the absence of an established pulmonary rehabilitation (pr) program. this is a non-randomized clinical trial of participants at the atlanta veterans affairs medical center with an applicable diagnosis for cardiac or pulmonary rehabilitation versus usual care during the study period. we will evaluate the outcomes related to smartphone-enabled home base cardiopulmonary rehabilitation in those who choose the intervention and those who opt into home-based cr, traditional cr, or those who decline. data from the past 5 years will also be evaluated to obtain a baseline event rate. investigators seek to address the following: 1. determine whether a home-based cardiac or pulmonary rehabilitation program delivered through smartphones is feasible and improves functional status. 2. determine if education and lifestyle counseling lead to increased adherence with prescribed follow-up, pharmacotherapy, quality of life, self-efficacy and lifestyle changes. 3. determine if a home-based cardiac or pulmonary rehabilitation program reduces health system utilization, including ed visits and readmission rates.
