| Sumario: | Objective of this study is to test the efficacy of a TBI, OPtimizing Technology to Improve Medication Adherence and BP Control (OPTIMA-BP), as an approach to support hypertension self-management to improve BP, health-related quality of life (HRQOL), and long-term compliance in African Americans with hypertension. Methods: This prospective, 2-arm randomized trial conducted in the Midwest will enroll African American older adults with hypertension, 50 years of age and older, recruited from primary clinics and community settings. Participants are allocated in a 1:1 ratio using computer-generated randomization to OPTIMA-BP intervention (n = 104) or Waitlist control group (n = 104). Participants are asked to participate in the study over a 12-month period and complete 5 study visits. Individuals in the OPTIMA-BP intervention group will receive three technology components (web-based education, medication adherence mHealth app, study provided home BP monitor), coupled with nurse counselling and communication to providers for guideline-directed treatment regimen. We will also collect data on knowledge-attitude mechanisms of self-management (hypertension knowledge, self-efficacy, perceived social support) and proximal behavioral mechanisms (antihypertension medication-taking, diet, exercise). Qualitative analyses will explore participants' experiences with self-managing hypertension using technology. Results: Participant recruitment began in March 2022, and is currently ongoing. It is anticipated that preliminary findings appropriate for analysis will be disseminated in Summer 2025. The primary endpoint is a change in BP (< 130/80 mmHg) and improved HRQOL. Conclusion: Using TBI along with standard preventive measures provides a unique opportunity to improve BP control and enhance secondary cardiovascular disease prevention in this high-risk group.
