View original scientific description
The LINKED- HEARTS Program is a multi-level project that intervenes at the practice level by linking home blood pressure monitoring (HBPM) with a telemonitoring platform (Sphygmo). The program incorporates team-based care by including community health workers (CHWs) and pharmacists to improve the outcomes of multiple chronic conditions (reduced blood pressure (BP), lower blood sugar, and improved kidney function). The LINKED-HEARTS Program will recruit a total of 600 adults with uncontrolled hypertension (BP ≥ 140/90 mm Hg) AND either type 2 diabetes or chronic kidney disease (CKD) across 16 community health centers or primary care practices serving high-risk adults. This cluster-randomized trial consists of two arms: (1) enhanced "usual care arm," wherein patients will be provided with Omron 10 series home BP monitors and will be managed by the patients' primary care clinicians as usual; and (2) the "intervention arm" which will integrate HBPM telemonitoring, a CHW intervention and provider-level interventions into the usual clinical care to improve BP control and provide support for self-management of chronic conditions. The study pharmacist will conduct telehealth, use the Sphygmo app and the Pharmacist Patient Care Process to collaborate with other providers to optimize pharmacologic therapy to improve hypertension outcomes and with payors to ensure consistent access to drug therapy.

Frequently asked questions
What is a clinical trial?
A clinical trial is a research study that tests new medical treatments, drugs, devices, or procedures to determine their safety and effectiveness. Trials are carefully designed and monitored to protect participants while advancing medical knowledge.
Is it safe to participate?
Clinical trials follow strict safety guidelines and ethical standards. Trials must be reviewed and approved, and participants are closely monitored by medical professionals throughout the study. You can withdraw at any time if you choose.
Will I be compensated?
Many clinical trials offer compensation for your time, travel expenses, and inconvenience. The specific compensation varies by study and will be discussed during the screening process. All study-related medical care is typically provided at no cost to participants.
Will I receive a placebo instead of treatment?
When effective treatment exists, participants typically receive either the standard treatment plus the study intervention, or the standard treatment plus placebo. You would not be denied effective care. Placebos are primarily used when no proven treatment is available, or in addition to standard care. Your trial consent form will clearly explain what treatments you may receive.
Can I leave a trial if I change my mind?
Absolutely. Participation in clinical trials is completely voluntary. You have the right to withdraw from the study at any time, for any reason, without penalty or loss of benefits to which you are otherwise entitled.
How long does a clinical trial last?
Trial duration varies widely depending on the study design and purpose. Some trials last just a few weeks, while others may continue for months or years. The study coordinator will provide specific timeline information during your screening call.
