Background

Hypertension affects over 116 million adults in the United States, with direct costs projected to exceed $220 billion by 2035. Over one third of Americans with hypertension are not aware they have it. Despite the existence of proven interventions, only 48% of patients who are diagnosed with hypertension have their condition controlled. 

Disparities are well documented in hypertension treatment, control and outcomes. The prevalence of hypertension among Black Americans is much higher than among non-Hispanic white Americans, and deaths attributable to hypertension are twice as frequent.

In Durham County, the prevalence of hypertension is 42%, with a strong association with residential racial isolation. This data suggests opportunities to intervene at a neighborhood level to reduce hypertension disparities and improve overall population health.

Project Description

Building on the work of previous teams, this project will focus on evaluating the policy implications of the January 2022 ruling from the Centers for Medicare and Medicaid Services and the Agency for Healthcare Research and Quality. This ruling was designed to close the gap in health disparities and treatment outcomes for persons with uncontrolled hypertension by enabling patient-reported self-monitored blood pressure readings to “count” as valid and reliable healthcare quality measures. It is also meant to advance the value and visibility of patient-reported blood pressure and to expand payment options and reimbursement models for healthcare systems, clinics and providers. 

The team will also strive to engage patients in learning the digital literacy skills required for self-monitored blood pressure reporting as an evidence-based approach to improving care of uncontrolled hypertension.

Team members will design and implement an intervention to encourage participation in a blood pressure reduction initiative. They will conduct 1:1 telephone outreach, teach classes and partner with community organizations to achieve this goal. The team will also create a portfolio of policy briefs, blogs and journalistic pieces for lay leaders.

Anticipated Outputs

Delivery of blood pressure cuffs; improved website access to Zoom platform for classes; policy briefs, blogs and journalistic pieces

Student Opportunities

Ideally, this project team will include 4 graduate students and 20 undergraduate students. Applicants may come from a variety of academic backgrounds, including healthcare disciplines (nursing, medicine and behavioral science) as well as population health, health policy and the humanities. Students with additional social science backgrounds are encouraged to apply.

Students will have the opportunity to contribute to publications and presentations at a number of national professional forums, including the American Heart Association Scientific Sessions; the American Academy of Nursing’s Transforming Health, Driving Policy Conference; the American Public Health Association’s Annual Meeting; and the AcademyHealth Annual Research Meeting. 

This project includes an optional summer component in 2023. Students will work approximately 10-20 hours per week for eight weeks during June and July.

Vivien Wambugu will serve as project manager.

Timing

Summer 2023 – Spring 2024
