Uncontrolled hypertension remains one of the most persistent and deadly health disparities in the United States, with Black adults bearing a disproportionate burden of cardiovascular mortality. An intervention that demonstrably narrows that gap — using scalable digital tools rather than costly new infrastructure — deserves serious attention from clinicians and health system designers alike.
This observational study evaluated a telehealth navigator program embedded within a Federally Qualified Health Center (FQHC) network in Massachusetts, targeting Black adults with a confirmed hypertension diagnosis. The program combined enhanced care coordination with remote patient monitoring (RPM). Researchers applied a staggered difference-in-differences design with doubly robust regression and inverse propensity weighting to compare blood pressure control rates — defined as readings below 140/90 mmHg — before and after enrollment, against a matched group of never- or not-yet-enrolled patients. Secondary outcomes included total primary care visit volume. The analytic unit was the patient-month, allowing granular tracking of longitudinal changes across the study cohort drawn from electronic health records.
The findings enter a growing but still incomplete evidence base for tech-assisted care coordination in safety-net settings. RPM combined with human navigation addresses a well-documented failure mode: patients who receive devices but lack the support infrastructure to act on readings. The navigator component is arguably the more important element — prior trials suggest that RPM alone produces modest or inconsistent results without accompanying behavioral support. Key limitations here include the single-network, single-state design, which constrains generalizability, and the observational architecture, which cannot fully rule out selection effects despite sophisticated weighting. The cohort is also defined by data availability rather than randomization. Still, for a population historically underserved by both clinical trials and digital health investment, this represents a practically meaningful, incrementally confirmatory addition to the literature on equity-focused hypertension management.
