The goal of this randomized controlled trial is to tailor a health communication intervention to improve functionally health illiterate (FHI) patients' management of their hypertension and to evaluate the impact of this intervention on health outcomes. The investigators expect the intervention will improve FHI patients' management of their hypertension and the study will demonstrate an effective and cost-efficient method for clearly conveying health information to FHI adults.

Study summary:

The proposed research will develop a cost-effective, health communication intervention specifically for the purpose of improving BP control among patients with low levels of functional health literacy. Its objectives are: - To enroll 250 FHI, hypertensive individuals from primary care clinics into the randomized controlled study; - To implement a health communication intervention in which a nurse delivers personally tailored information about BP management over the phone to the patient, using standardized scripts and complementing the phone intervention with visual aids and support of a family member or friend; - To evaluate the effectiveness of the intervention on a primary clinical outcome measure -- blood pressure control; - To evaluate the intervention's effect on secondary outcome measures -- changes in hypertension risk perception, satisfaction with care, patient confidence following recommended regimen, and self-reported adherence to recommended regimens. We expect to demonstrate improved health outcomes, measured by BP control (<140/90 mm/Hg), as a result of the intervention. If successful, our intervention will constitute an important health communication tool specifically designed to improve BP control of patients with low health literacy.
