Brief Summary

Review the sponsor-provided synopsis that highlights what the study is about and why it is being conducted.

This pragmatic randomized crossover trial looks at the effect(s) of using a remote patient monitoring device (Heartfelt device) with health alerts to monitor the development of peripheral edema in patients with heart failure (HF). The hypothesis is that this passive measurement method will lead to better data availability, which in turn will improve patient care and reduce hospitalizations for the management of worsening HF (HF hospitalizations, HFHs) in nonadherent participants with chronic HF. The study objectives are:

* Primary objective: Establish if the Heartfelt device is safe to use and effective at reducing HFHs.
* Secondary objectives:

1. Establish the effect of the Heartfelt device on data availability compared to existing remote monitoring devices.
2. Establish the effect of the Heartfelt device on HF clinical outcomes.

Participants will need to:

* Install the device in their home for at least a year and up to 4 additional years after.
* Reply to remote patient monitoring phone calls to follow the care plans.

Detailed Description

Dive into the extended narrative that explains the scientific background, objectives, and procedures in greater depth.

Participants will be recruited through Remote Patient Monitoring Providers (RPMPs) based in the US, using crossover randomization between standard care and Heartfelt device usage with health alerts sent to RPMPs. The RPMPs will follow a protocolized intervention when responding to raised alerts.

The study design is a crossover randomization between:

* Standard care (control), 162 days: The device is installed in the home and captures data but no health alerts are sent, and the RPMP does not receive data from the device. (Health alerts are generated and stored for review at the end of the study period to correlate with health issues which occurred during usual care).
* Standard care + Heartfelt (intervention), 162 days: The device captures data and transmits volume measurements and health alerts to the RPMP for review. RPMPs follow a pre-specified alert protocol, potentially following up with the patient.

At consent, patients get randomized to an install date over a period from 21 to 60 days following consent, subject to scheduling this at least 14 days after the most recent recorded hospital discharge at the time of consent, or the discharge from their current hospitalization if hospitalized at the time of consent.

Total study length is 366 days (days 0 to 365). There are two 21-day "washout" periods to prevent carryover between study arms. The first washout period extends from day 0-20 inclusive, and the second from day 183-203 inclusive

At the completion of both crossover arms, patients will be offered the opportunity to keep the device for as long as the study remains active (potentially up to an additional 4 years, for those patients recruited early in the study). During this long-term follow-up, the device will be placed in "Intervention" mode, with randomized 100-day periods where the device is switched into "Standard care" mode (control).

Allocation Method

RANDOMIZED

Intervention Model

CROSSOVER

This trial is a crossover randomized study with two arms:

1. Standard Care (control): Device is installed and data is captured but volume measurements and health alerts are not transmitted to the RPMP;
2. Standard Care + Heartfelt (intervention): Device is installed and data is captured, and volume measurements and health alerts are transmitted to the RPMP for review and potential follow-up (per a pre-specified alert protocol).

Optional long-term follow-up where the device will be placed in "Intervention" mode, with randomized 100-day periods of "Standard care" mode (control).
Primary Study Purpose

PREVENTION

Blinding Strategy

SINGLE

Outcome Assessors
Participants cannot be effectively blinded as they receive feedback from the RPMP in the intervention arm, and false alerts could alter the control arm's dynamics. The RPMP cannot be effectively blinded to study arms due to access to additional patient data (such as weighing scale data) to compare to any "fake" foot volume data that might be provided.

The focus of blinding is the Clinical Events Committee (CEC), which will adjudicate if events recorded in the EHR/Claims data count as outcome events. There is no reason for the CEC to have access to logs of contact with patients or data measured with the Heartfelt device. Prior to EHR/Claims data-derived data being provided to the CEC, it will be cleansed of any such potentially-unblinding data. This ensures unbiased outcome assessment, with the CEC not accessing device alert data.
