The available evidence suggests that the device reliably detects atrial fibrillation and may increase the rate of detection when used in primary care during hypertension screening. People suspected of having atrial fibrillation after use of ‘WatchBP Home A’ should have an electrocardiogram (ECG) in line with NICE clinical guideline 36, Atrial fibrillation.

Use of WatchBP Home A in primary care is associated with estimated overall cost savings per person, ranging from £2.98 for those aged between 65 and 74 years to £4.26 for those aged 75 years and over.

Cost analyses did not support the use of the device by patients in their homes.
