Plain English Summary
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.

Study hypothesis
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.

Results and Publications
Publication and dissemination plan
This was a very small pilot and development study that mainly concentrated on the development of the website, and was used as the basis for arguing for a much larger Programme grant subsequently funded by NIHR PGfAR: the trial from that Programme will be published and the data will be made available.
Intention to publish date
Individual participant data (IPD) Intention to share
No
IPD sharing plan
The datasets generated during and/or analysed during the current study are not expected to be made available due to the fact that this was preliminary pilot work.
