Remote monitoring program improves blood pressure control in underserved patients

Background and goal: Underserved communities are at higher risk for uncontrolled high blood pressure (hypertension), which can lead to heart disease and higher death rates. This study evaluated the impact of a remote monitoring program called DIG IT on blood pressure control in underserved patients at a Federally Qualified Health Center (FQHC) in Orange County, California.

Study approach: Researchers compared two groups: 70 patients using the DIG IT program, which includes digital blood pressure monitoring, medication management, and a team-based care approach, and a historical control group of 70 patients who received standard care without digital tools. The study focused on patients aged 40 and older with uncontrolled hypertension. Researchers tracked blood pressure readings and heart disease risk scores over three months.

Main findings: 

• Patients in the DIG IT program saw their systolic blood pressure drop by an average of 31 points. This is compared to a reduction of just 15 points in the control group. Diastolic blood pressure decreased by 11 points in the DIG IT group, compared to a 5-point reduction in the control group.

• The program led to a significant reduction in the estimated American College of Cardiology 10-year risk of heart disease. Patients in the DIG IT group showed twice the improvement compared to those in the control group.

• Nearly 73% of patients in the DIG IT program reached their blood pressure goals within three months, compared to 37% in the control group.

Why it matters: These findings show that remote monitoring programs, like DIG IT, can significantly improve blood pressure control and lower heart disease risks in underserved communities. By connecting digital health tools with real-time care, these programs provide timely interventions crucial for managing chronic diseases.
