RecoveryPlus Telerehab Platform Pilot Study

Study Overview
=================
Brief Summary
-----------------
In this prospective, single-arm study, we will look at the initiation, participation, sustained engagement, and safety of 100 adult subjects (ages 45 years or older) with recent (within the past 60 days) clinician referral to CR who are offered CTR via the RecoveryPlus platform. We want to understand the effectiveness of the RecoveryPlus platform in engaging participants in CR while remaining a safe alternative for the delivery of evidence-based CR content. The primary hypothesis of this study is that the RecoveryPlus CTR platform and patient-facing mobile application provide a safe alternative to traditional in-person CR, and demonstrate a high rate of initiation, participation, and engagement in CR exercise programming than traditional modes of CR delivery, as documented in the literature. Current in-person and non-personalized CR programming lacks RecoveryPlus' convenient remote access, easy-to-use digital tools to support independent, autonomous exercise, and a platform to facilitate engagement and feedback between patients and EPs.

Detailed Description
-----------------
1 BACKGROUND INFORMATION AND RATIONALE 1.1 Introduction Cardiac rehabilitation (CR) is an evidence-based program designed to help individuals with heart disease recover and improve their physical, psychological, and social functioning. CR is an important component in the management of patients with cardiovascular disease, which aims to reduce the risk of subsequent cardiovascular events and improve quality of life. However, traditional modes of CR delivery such as in-person sessions, have limitations, including low participation rates and inconvenience for patients. Telehealth technology may provide a viable alternative, and the RecoveryPlus platform has been developed specifically to deliver evidence-based CR content remotely. 1.2 Clinical Need Cardiovascular diseases (CVDs) are the leading cause of morbidity and mortality worldwide, and their incidence and prevalence have steadily risen over the past decades. Several common cardiovascular diseases include coronary heart disease, heart surgery cerebrovascular disease, rheumatic heart disease, deep vein thrombosis, congestive heart failure, and pulmonary embolism. The Million Hearts Cardiac Rehabilitation Collaborative, co-led by the Centers for Disease Control and Prevention (CDC) and the Centers for Medicare and Medicaid Services (CMS), aimed to prevent one million CVD events by 2027. However, there were only 2,300 CR programs in the U.S. in 2021. 1.3 Clinical Rationale This study will capture metrics that demonstrate the effectiveness and safety of RecoveryPlus in engaging participants in a 12-week, hybrid, synchronous/asynchronous remote CR program, thus contributing to study subjects' recovery from a precipitating cardiac health condition. 1.4 Design Rationale Given that RecoveryPlus is a remote CR platform that includes synchronous telehealth visits with a licensed Exercise Physiologist (EP) and a patient-facing mobile application offering tools for asynchronous exercise guidance, the study will be conducted entirely remotely. Study data, including clinical endpoints, will be collected per usual RecoveryPlus program participation. 1.5 Proposed Solution Safe, effective remote cardiac telerehabilitation (RCR) offers a scalable solution to the need for greater engagement of patients recovering from CVD events in evidence-based CR exercise programming. CR generally is a multi-faceted approach that combines exercise training, patient education, nutritional counseling, risk factor behavior modification (e.g., around management of lipids, blood pressure, weight, smoking) to improve outcomes of patients with CVD and reduce associated morbidity and mortality.4 In particular, physical activity has become a core component of CR programs as mortality risk is lower among patients who meet WHO recommendations for physical activity.5 Over the past decade, the use of home-based programs for CR has become more prevalent, as they expand access to rehabilitation for patients with limited mobility, and allow providers to manage a broader panel of patients.4 As with many healthcare services, the COVID-19 pandemic accelerated the transition of many CR programs to home-based care, also termed telerehabilitation or CTR.6 Status Quo: CR is a safe, effective, evidence-based intervention that remains severely underutilized by patients for a variety of reasons, including: inconvenience, lack of incorporation of patient input and capacity for personalization, and poorly designed, static content. Therefore, while proven effective, the lack of initiation and engagement of patients in CR programming means it falls short of its potential to widely impact patient outcomes. 1.6 Device Description RecoveryPlus has developed an innovative CTR platform for patients with CVD that leverages: (1) video conferencing for synchronous telehealth sessions of CR instruction for patients and licensed EPs, (2) a patient-facing mobile application delivering asynchronous exercise videos, and (3) a health care provider web portal for clinicians and EPs. The RecoveryPlus platform includes the ability for EPs and clinicians to monitor patient clinical data (e.g., heart rate) and input (e.g., rating of difficulty for individual exercises) and tailor individual patient regimens regularly for increased safety and optimal outcomes. The main goal of RecoveryPlus is to engage and motivate patients to achieve sustained engagement in their cardiac rehabilitation in a safe environment. The RecoveryPlus team has done this by solving the problem experienced by medical professionals who otherwise lacked reliable clinical and adherence data needed to understand patients' CR experience in real-time. The solution is a purpose-built platform incorporating synchronous telehealth visits with licensed EPs along with a mobile medical application to be used for asynchronous exercise instruction. With exercise videos and personalized heart rate targets, and continuous readings during exercise sessions, RecoveryPlus provides patients with more robust instruction, monitoring, and support, and medical professionals the tools to guide patients' exercise, track patients' heart rates and receive patients' feedback. Data derived from a heart rate monitor as well as the patient's feedback is reviewed by medical professionals to assess exercise intensity, the patient's conditions, and adherence to the prescribed exercise. Patients are asked for frequent feedback on their exercise experience. Individual exercises are followed by prompts to rate the perceived level of difficulty [1-10 scale] of the exercise. If a patient chooses to skip an exercise, the app asks the reason [too hard, cannot reach target HR, pain, personal reasons] and requires qualitative characterization of the reason before being allowed to continue. If a patient chooses to exit a session prior to completion, the app asks for a reason [uncomfortable, too tired, movement too hard, personal business] and requires qualitative characterization of the reason. Unlike current practice, the RecoveryPlus platform provides the capability for real-time, automated alerts sent to RecoveryPlus personnel for any negative symptom report or out-of-range heart rate reading and immediate evaluation to determine the severity of a symptom and what follow-up course of action is required (if any). Patients are instructed as part of regular RecoveryPlus programming practice to stop exercising and report any cardiac-related symptom to their clinician or EP at any time, during or outside of exercise sessions. RecoveryPlus staff receive and respond to alerts 24 hours/7 days per week. The healthcare provider web portal allows clinicians and EPs to enter a patient's basic demographic and clinical information, create fitness assessments, define and update a patient's exercise prescription, provide educational information, and generate wellness reports.

What is the study measuring?
-----------------
Primary Outcome Measures

| Outcome Measure | Measure Description | Time Frame |
| --- | --- | --- |
| INITIATION | Initiation will be defined as the proportion of enrolled screen-eligible patients who completed all baseline assessments and completed the initial CTR session. | 3 months | 
| PARTICIPATION | Participation will be defined as the proportion of prescribed CTR sessions per participant that are completed (51% or more of prescribed session length completed) throughout the 12-week study period. | 3 months | 
| SUSTAINED ENGAGEMENT | Sustained engagement will be defined as the proportion of enrolled participants who had a minimum of 1 completed session, synchronous and/or asynchronous, per week (within each 7day interval from the initial session) for at least 9 weeks of the 12-week study period. | 3 months | 
| SAFETY | Safety will be measured as the total number of adverse events over the entire course of the 12-week study period. | 3 months | 

Secondary Outcome Measures

| Outcome Measure | Measure Description | Time Frame |
| --- | --- | --- |
| 6-minute WALK TEST | This endpoint will be defined as the difference in fitness as measured by performance on a 6-minute walk test from baseline to endline. The 6-minute walk test is a widely used and well documented measure of aerobic exercise capacity used to indicate change in fitness.7 In this test, one measures the distance an individual is able to walk over a total of six minutes on a hard flat surface. Per routine RecoveryPlus practice, the EP will instruct participants virtually on completion of the test at baseline and again at endline. | 3 months | 
| RESTING HEART RATE | This endpoint will be defined as the difference in fitness as measured by resting heart rate from baseline to endline. Resting heart rate is positively associated with mortality and is known to lower with regular exercise. Per routine RecoveryPlus practice, the EP will instruct participants virtually on completion of resting heart rate assessment at baseline and again at endline. | 3 months | 
| QUALITY OF LIFE | QoL will be defined as the difference in score on the Short-Form Health Survey (SF-36), a validated and commonly used measure of patient perceived quality of life and functional health and wellbeing, from baseline to endline.8 During the initial teleheath evaluation appointment, EPs will provide a link to a secure web form and facilitate participant completion of the baseline SF-36 online; after 12 weeks, EPs will facilitate completion of an endline SF-36 using the same process. | 3 months |
