Brief Summary:
The purpose of this study is to determine if the use of home blood pressure monitors plus nurse telephone monitoring is more effective than the use of blood pressure monitors alone in improving control of high blood pressure in an urban medical clinic.

Condition or disease Intervention/treatment Phase
Hypertension Device: Home monitoring Other: monitor & phone call Phase 1

Detailed Description:
Participants will all have home blood pressure monitors, education session on controlling their blood pressure and will be randomized to recieve 6 months of intensive telephonic on a set monitoring schedule or no telephonic follow up. Phone calls will be weekly for 4 weeks, then every 2 weeks for 8 weeks then monthly for 3 months.

Study Type : Interventional  (Clinical Trial)
Actual Enrollment : 111 participants
Allocation: Randomized
Intervention Model: Parallel Assignment
Masking: None (Open Label)
Primary Purpose: Treatment
Official Title: A Structured Program for Hypertension Control in Community Clinics: A Randomized Trial
Study Start Date : April 2008
Actual Primary Completion Date : June 2015
Actual Study Completion Date : June 2015

Arm Intervention/treatment
Active Comparator: home monitoring
home blood pressure monitor
Device: Home monitoring
Participants will receive a home blood pressure monitor and be taught how to use it. They will have an education session to review treatment goals, medications, diet and exercise. They will be asked to see their primary care provider at least every 3 months and the research nurse at 3, 6 and 12 months.
Experimental: monitor & phone call
home blood pressure monitor + phone calls
Other: monitor & phone call
Participants will receive all of the same interventions of the home monitoring group plus they will receive scheduled telephone follow up by the research nurse

Primary Outcome Measures :
  1. Blood Pressure [ Time Frame: at 6 mo and 12 mo after randomization ]

Secondary Outcome Measures :
  1. Blood pressure measured at home [ Time Frame: 6 and 12 months post randomization ]
  2. Compliance with use of home blood pressure monitor [ Time Frame: 6 and 12 months post randomization ]
  3. Number and type of antihypertensives prescribed [ Time Frame: 12 months post randomization ]
  4. Patient satisfaction and Quality of Life [ Time Frame: 6 and 12 months post randomization ]
  5. Primary care provider satisfaction with intervention [ Time Frame: 6 mo post randomization of a provider's first patient to enroll in the trial ]
  6. Number of primary care provider visits [ Time Frame: 12 months post randomization ]
  7. Number and quality of adverse events [ Time Frame: 3, 6, and 12 months post randomization ]
  8. cost analysis [ Time Frame: 12 months post randomization ]
