The specific aim of the study is to assess the impact of an Internet-enabled, automated, self-management program on blood pressure control of employees of a large local company.

Condition Intervention
Blood Pressure
Other: Internet-enabled automated self-management program
Other: BP cuff at workplace

Study Type: Interventional
Study Design: Allocation: Randomized
Intervention Model: Parallel Assignment
Masking: Open Label
Official Title: Blood Pressure Self Management for Hypertension & Prehypertension Using an Internet Enabled, Automated Self Management Program

Further study details as provided by Massachusetts General Hospital:

Primary Outcome Measures:
  • Change in systolic blood pressure. [ Time Frame: 6 months ]

Secondary Outcome Measures:
  • Assess whether the intervention increases the motivation and self-efficacy of patients managing blood pressure. Assess patient satisfaction with the intervention. Assess the impact of the intervention on healthcare utilization and expenditure [ Time Frame: 6 months ]

Enrollment: 404
Study Start Date: April 2007
Study Completion Date: December 2008
Primary Completion Date: December 2008 (Final data collection date for primary outcome measure)
Arms Assigned Interventions
Experimental: Intervention
Internet-based hypertension self-management platform
Other: Internet-enabled automated self-management program
An internet platform to display blood pressure readings and provide subjects with automated messages and educational information about hypertension management.
Active Comparator: Control
Installation of BP cuff for communal use at the worksite
Other: BP cuff at workplace
Provided BP cuff for communal use at the worksite

Detailed Description:

We propose to conduct a randomized controlled trial of an Internet-enabled, automated self-management program. The study will be carried out through six local sites (offices) of a large employer. 3 sites will be intervention sites and 3 will be control sites.

Subjects enrolled from the intervention sites will receive a blood pressure meter and access to an Internet site where they can view their readings, read educational material regarding hypertension management and receive personalized tips and feedback.

Subjects enrolled from the control sites will have access to a blood pressure monitor located at their workplace but will only be provided with basic written information about hypertension at the start of the trial and will receive no feedback.

The trial will run for 6 months from the time of enrollment and the primary outcome measure will be a change in systolic blood pressure.
