Smart Wearable Insights to Prevent Exacerbations and Recurrence - Rehabilitation Study: SWIPER-REHAB

Aims of the study:

* To measure the rate of completion of a digital cardiac rehabilitation programme at Imperial College Healthcare NHS Trust (ICHNT) * To measure the health economic impact of a digital cardiac rehabilitation programme at ICHNT

Any adult patient eligible for ICHNT cardiac rehabilitation (CR) programmes is eligible to participate. Participants will receive a commercially available smart watch and be asked to wear the device as much as possible. In addition, they will be asked to download a smartphone application called 'Imperial Healthy Hearts', which displays movement and information on heart rate, breathing and oxygen levels to both the participant and the research team (digital data). The Healthy Hearts app also allows the direct care team to provide educational materials to patients as part of their routine care.

The clinical content and structure of the CR programme is determined by the clinical CR team, and does not deviate from established local and national standards and practices.

Researchers will capture physiological data such as heart rate, respiratory rate, blood pressure (where available) and oxygen saturation (where available) via the Healthy Hearts platform. Researchers will also capture clinical information from the electronic health record, and will compare CR programme uptake and completion rates with historical data and national targets.
