Blood Pressure Self Management for Hypertension & Prehypertension Using an Internet Enabled, Automated Self Management Program

Study Overview
=================
Brief Summary
-----------------
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.

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.
