Plain English summary of protocol
Background and study aims
This study addresses overlapping issues in patient engagement: a patient support tool to implement a lifestyle intervention that practice nurses currently do not have the time and expertise to implement, and home blood pressure measurements with self-titration (dose adjustment) of medication for lowering blood pressure.
Who can participate?
Patients aged over 18 with high blood pressure
What does the study involve?
The study involves two phases. In Phase 1 the LifeGuide web tool, diet materials, and web pages used in an obesity web intervention (on diet and exercise) are used as the basis for writing the initial web pages for the web intervention. Focus groups and 1:1 interviews with patients and nurses are used to modify the site. In Phase 2 patients are randomly allocated to one of three groups. The first group receive usual care (normal clinic measurement by a GP or nurse). The second group use home blood pressure measurement with telemonitoring. The third group use home blood pressure measurement with telemonitoring and receive access to the lifestyle website with reinforcement by the practice nurse over a 3-month period. After 3 months the changes in blood pressure in the three groups are compared.

| Scientific title | Self Measurement and management using the Internet for Lowering blood pressure in Everyday practice: a randomised controlled trial |
| Study acronym | SMILE |
| Study objectives | This study addresses overlapping issues in patient engagement: 1. A patient support tool to implement lifestyle intervention (the effective and acceptable DASH diet and exercise) that practice nurses currently do not have the time and expertise to implement 2. Home blood pressure measurements with self titration of medication It involves two distinct phases, the initial development of a web intervention followed by a randomised controlled trial to explore the extent to which the interventions can change. |
