Plain English summary of protocol

Background and study aims
The number of adults with high blood pressure, or hypertension, doubled from 650 million in 1990 to 1.3 billion in 2019. Many people don't know they have high blood pressure or don't have it under control. Traditional methods to measure blood pressure use an arm cuff, which can be uncomfortable and sometimes gives inaccurate readings. Other illnesses related to having high blood pressure put a burden on patients and healthcare systems. Using a small, non-invasive at-home device is a possible way of reducing the number of people with high blood pressure and its associated complications worldwide.
This study will observe how blood pressure changes over time using the Aktiia 24/7 device, a comfortable wrist-worn device that measures blood pressure continuously. We want to see how blood pressure changes over time, and how people feel about using this device over 12 weeks. The Aktiia device will be sent directly to the participant's home, who will wear the bracelet 24/7 for 12 weeks. Participants will be asked to download the Aktiia phone application (app) on their smartphone and perform weekly syncs of the device with a cuff and the app.

Who can participate?
We are inviting individuals to participate in this study who are aged 22 - 85 years, with a blood pressure reading within the last 12 months that was either systolic ≥145 mmHg and/or diastolic ≥90 mmHg. This reading can be one taken by a medical professional (e.g. doctor, nurse, pharmacist) or a reading taken from a reliable CE-marked at-home blood pressure measuring device. A member of the study team will check whether you are suitable for the study based on the study eligibility criteria and the blood pressure reading you provide.

What does the study involve?
The study will last for approximately 12 weeks. Participants will be asked to complete some online forms at the beginning of the study, taking around 5 minutes and two questionnaires in the Aktiia study app, one when they first use the Aktiia device and the other at the end of the 12 weeks. Participants may be asked to upload evidence of their high blood pressure (e.g. via a picture of a blood pressure reading or a blood pressure medication, or a screenshot of their medical record in the NHS app) when they join the study. This will be used to confirm they are suitable for the study. Participants will wear the Aktiia bracelet for 12 weeks and should perform weekly syncs of the bracelet with the cuff and app. The app will send notifications to remind participants to do this. Once participants have completed the study, they will keep the device and be prompted to download the app available on app stores. They will also receive a £50 payment or voucher if they have completed all study activities (3 questionnaires and 12 weekly syncs with the cuff and app).

What are the possible benefits and risks of participating?
Taking part in this study may not have any direct benefit to participants, but their participation may help to generate knowledge on how the device could be used in the future to improve management of high blood pressure. In addition, the Aktiia 24/7 device offers continuous blood pressure monitoring, providing participants with a more comprehensive understanding of their blood pressure over time.
The Aktiia 24/7 device is not expected to cause any side effects. The device should be kept clean to prevent skin irritation on the wrist. The device is ‘CE marked’, which means the manufacturer has checked that the device meets certain safety, health and environmental requirements. Using the device may indicate that participants have dangerously high blood pressure. There will be no medical follow-up by the study team if high readings are recorded. If participants are concerned about the blood pressure readings they see on the device, they are asked to seek medical help as soon as possible, via usual care e.g. via their GP or by calling 111.

Scientific titleBlood pressure evolution and user satisfaction in a hypertensive population using the Aktiia 24/7 Optical Blood Pressure Monitoring (OBPM) device: a prospective observational cohort study
Study acronymSHINE
Study objectivesThe SHINE study aims to gather data on the evolution of participant's blood pressure and to correlate this with demographic, lifestyle and health factors in a hypertensive population as well as, to gather data on participants' perception of the device under test (Aktiia 24/7).
Ethics approval(s)

Approved 15/07/2024, London – Queen Square REC (2 Redman Place, Stratford, London, E20 1JQ, United Kingdom; +44 207 104 8284; queensquare.rec@hra.nhs.uk), ref: 24/PR/0776

Health condition(s) or problem(s) studiedHypertension
InterventionEach study subject will receive an Aktiia device and will use it continuously for 12 weeks. Study participants will have to complete two different surveys: one at baseline, and one after 23 weeks of Aktiia device use to give their perception on the Aktiia device use as compared to other blood pressure monitors currently on the market.
