Research summary
Summary of Research
The VISION-RWE study aims to test whether a novel software-based blood pressure (BP) monitor called Lifelight is as good as the conventional method of home blood pressure monitoring for helping people with high BP keep their blood pressure at safe levels. Lifelight allows patients to monitor their blood pressure contactlessly, without needing to do any calibration and using only their smartphone. The conventional method is a popular upper-arm blood pressure cuff and monitor.
Study participants (18 yrs & older) will be patients with high blood pressure who are not at target for their blood pressure control. 500 participants will be recruited and monitored at William Harvey Clinical Research Centre, Barts Health NHS Trust. 250 participants will be provided Lifelight and the other 250 will be provided a standard blood pressure cuff and monitor. They will be asked to use these devices to monitor their blood pressure for at least 1 week each month, lasting for 6 months. They will be seen in the clinic 3 times (at the beginning, after 3 months and after 6 months) as part of the study for study nurses to evaluate if their blood pressure control is improving by self-monitoring as they progress through the study.
Participants will note down the home blood pressure measurements they make in between these clinic visits in a paper diary. They will also record their experiences of using the traditional cuff-based blood pressure monitor or smartphone app assigned to them, details about any GP visits, hospital admissions etc that they have while they are in the study in this same diary. They will complete questionnaires about their quality of life, lifestyle and blood pressure monitoring habits in a questionnaire booklet on 3 occasions. Some participants using Lifelight will be invited to have an interview about their experiences in the study.Summary of Results
This study looked at whether adults with high blood pressure could use a new contactless technology to measure their blood pressure without a traditional cuff, in everyday settings.
A total of 249 participants were recruited before the study ended early. Most participants were older adults (average age around 61 years), and their starting blood pressure levels confirmed they had uncontrolled hypertension, meaning they were at higher risk of heart disease and stroke.
The study closed earlier than planned because a newer version of the technology received regulatory approval, making it inappropriate to continue evaluating the earlier version. Some participants completed follow-up visits at three and six months, but not enough people reached later visits to allow meaningful assessment of clinical outcomes.
Although we could not assess effectiveness, the study showed that it is possible to recruit people with hypertension into technology-enabled monitoring. Participant feedback highlighted practical issues such as sensitivity to lighting and movement, the need for physical phone supports, and the importance of reminders and easy access to previous readings. Many participants expressed interest in digital sharing of results with clinicians.
This feedback was used directly to improve the newer version of the device (Class II), including usability, accessibility, and integration into care pathways. The study also provided important learning about recruitment, onboarding, and how digital tools can fit into routine healthcare.
Overall, while the study did not generate clinical outcome results, it produced valuable insights that helped refine the technology and inform future research into digital approaches for managing high blood pressure.REC name
