Description

In this comparative effectiveness trial, we aim to answer the research question of whether a remote blood pressure management program (RBPM, inclusive of home blood pressure monitoring and telehealth visits with a nurse or pharmacist delivering protocol-supported BP management, inclusive of medications and lifestyle modifications) alone or an RBPM program with community health worker (CHW) support is more effective than standard screening with education and referral to primary care in controlling blood pressure and addressing social determinants that lead to poor health outcomes.

This is a multisite study using a stepped wedge design. Health systems in 4 different cities are each partnered with 10 community based organizations (CBOs). CBOs are randomized into one of 4 sequences. Each sequence moves through the 3 study arms at different time points: Community Standard, RBPM alone, and RBPM+CHW.

At the CBOs, research health advocates screen for hypertension. Qualifying individuals who provide informed consent can enroll in the study and are assigned to the intervention that the CBO is in at that particular time. All participants receive a blood pressure cuff and a device that syncs their data with the research database. If enrolled in the RBPM arm, participants are scheduled for telehealth visits with the Pressure Check medical team to improve blood pressure control through lifestyle support and medication initiation/titration. If enrolled in the RBPM+CHW arm, participants additionally receive support from a CHW to help with medical visits and address social determinants of health. The primary outcome is blood pressure control at 6 months. Additional outcomes include implementation science to understand factors associated with adoption and outcomes, and 12 and 18 month blood pressure control.

In partnering with the community, health systems can extend their reach. CBO leaders support health messaging around hypertension and increase trust between the health system and their clients (patients). The two models, RBPM alone and RBPM+CHW, are based on the concept that disparities in hypertension control among Black, Latinx, and low-income populations exist because of inequities related to health system access and trust, individual-level socioeconomic and lifestyle factors, the physical/built environment, sociocultural factors, and discriminatory policies. Addressing these barriers may improve blood pressure control.
