  Purpose

There are 65 million Americans and over 8.5 million veterans who have been diagnosed with hypertension; yet only 31% of all hypertensive patients have their blood pressure (BP) under effective control (less than 140/90 mm/Hg). Uncontrolled hypertension greatly increases the risk of cerebral vascular accidents, coronary artery disease, myocardial infarction, renal failure, congestive heart failure, and mortality. Despite the damaging impact of hypertension and the availability of well-defined therapies and widely accepted target values for BP, interventions to improve BP control have had limited success.

Primary Outcome Measures:
  • Blood pressure control and medication adherence [ Time Frame: Blood pressure measured at 6mo intervals, baseline, 6mo, 12 mo, & 18 mo ] [ Designated as safety issue: No ]

Secondary Outcome Measures:
  • Knowledge & perceived risks associated w/hypertension as determined by questionnaire; confidence w/hypertension regimen using a composite of 4 items; medication adherence (pill refill using calculated Med-out index for interventional period) [ Time Frame: Surveys administered at 6 mo intervals, baseline, 6mo, 12 mo, & 18 mo ] [ Designated as safety issue: No ]
  • Blood pressure control sustainability [ Time Frame: 6 mo-2 years after primary study completion ] [ Designated as safety issue: No ]
  • Intervention efficacy through process evaluation for understanding [ Time Frame: Questionnaire administered at follow-up appt 6 mo - 2 years after primary study completion ] [ Designated as safety issue: No ]
