The specific goals of this project are to (1) refine the Home Automated Telemanagement (HAT) program according to the JNC 7 Report based on focus group review conducted by the key personnel, primary care providers, and patients and to fully implement the multidisciplinary model for hypertension telemanagement in African Americans as an adjunct of ambulatory care and (2) evaluate in a randomized clinical trial the impact of HAT on hypertension care delivery and on patients' clinical outcomes using both clinic- and patient-level variables. The comparison will be made with the standard of hypertension care recommended by the JNC 7 Report.
