Improving Blood Pressure in Colorado

Completed · Not applicable

Conditions studied: Hypertension

In brief

We will improve hypertension control in Colorado by implementing a population-based intervention using interactive voice response (IVR) technology that will be delivered to patients in three healthcare systems across Colorado (Denver Health and Hospitals \[DH\], VA Colorado Healthcare System \[VA\], and Kaiser Permanente of Colorado \[KPCO\]). Together, these organizations serve over 1 million Coloradans. The IVR-based hypertension program will: 1) reach out to more patients using fewer resources than a traditional patient visit approach, 2) implement evidence based guidelines for therapy, 3) facilitate patients' acquisition of medications by allowing them to order and receive medications at home, and 4) enhance medication adherence using tailored educational and motivational messages. HYPOTHESES: 1. A sizable population of patients is at high risk for further cardiovascular morbidity and mortality, based on uncontrolled hypertension. 2. An IVR-centered intervention among patients with diagnosed but uncontrolled hypertension is feasible. 3. An IVR-centered intervention plus usual care for these patients improves BP control, compared to usual care alone.
