The goal of this study is to improve patients' management of their hypertension. We will examine the impact of a nurse administered patient tailored intervention and home blood pressure (BP) monitor on BP control. This 4-year randomized controlled trial will occur in a primary care setting among diagnosed hypertensive patients. The nurse-administered intervention is based on the principles of Health Decision Model and is designed to increase awareness, yet be easily implemented in patient care so as to enhance adherence with the prescribed regimen The use of home BP monitors has been found to be associated with increased self-management, adherence, and improved BP control. ? ? Elevated BP levels are a major risk factor for stroke, CAD, CHF, and renal disease. However, stroke rates are no longer improving and CHF and renal failure continue to increase in the U.S. Despite the high prevalence of hypertension, only approximately 25% of all hypertensive patients have adequate BP control. This study will be an important step in testing the effectiveness of both a nurse and self-administered intervention to improve BP control among a community sample. ? ? We will obtain consent from 530 hypertensive patients from 2 large Primary Care Clinics and randomly assign them to receive the nurse intervention alone, home monitoring alone, both interventions, or usual care. Based on baseline needs assessment, patients randomized to the nurse administered, tailored intervention will receive a telephone behavioral education intervention to promote adherence with medication, including support and reminders, information on the risks of hypertension, health behaviors, patient/provider communication, literacy, and side effects at periodic telephone contacts. Patients will receive continuous patient education and will be monitored and supported to enhance adherence. Patients assigned to the home BP monitors will record their BP bi-weekly and either provide this information to the intervention nurse or their provider. ? ? The primary outcome will be dichotomous, representing whether or not the patient's BP is >140/90 mm/Hg (nondiabetic) and >1 30/85 mm/1-Ig (diabetics) at each outpatient clinic visit. Descriptive statistics will be computed for all study variables stratified by treatment group. Because each patient may have a different number of unequally spaced observations over time, we will model the responses and evaluate the interventions using a mixed effects model for dichotomous outcomes. Based upon preliminary data, this study is expected to improve patients' management of their hypertension, decrease health are utilization and subsequentlv improve BP control.
