RT Journal Article SR Electronic T1 NICE atrial fibrillation guideline snubs wearable technology: a missed opportunity? JF Clinical Medicine JO Clin Med FD Royal College of Physicians SP 77 OP 82 DO 10.7861/clinmed.2021-0436 VO 22 IS 1 A1 Andre Briosa e Gala A1 Michael TB Pope A1 Milena Leo A1 Trudie Lobban A1 Timothy R Betts YR 2022 UL http://www.rcpjournals.org/content/22/1/77.abstract AB Atrial fibrillation (AF) is the most common sustained cardiac arrhythmia and a growing public health epidemic. In the UK, over 1.3 million people have a diagnosis of AF and an estimated 400,000 remain undiagnosed. AF-related strokes account for a quarter of all strokes and, as AF episodes are often asymptomatic, are still often the first manifestation of AF. Early diagnosis and initiation of oral anticoagulation, where appropriate, may prevent some of these thromboembolic strokes. Public Health England is committed to decrease the incidence of AF-related strokes and has sponsored initiatives aimed at improving AF detection by promoting the uptake of wearable technologies. However, the National Institute for Health and Care Excellence (NICE) has not recommended wearable technology in their recent AF diagnosis and management guidelines (NG196). Diagnostic accuracy of single-lead electrocardiography (ECG) generated by the latest iteration of wearable devices is excellent and, in many cases, superior to general practitioner interpretation of the 12-lead ECG. High-quality ECG from wearable devices that unequivocally shows AF can expedite AF detection. Otherwise, there is a real risk of delaying AF diagnosis with the potential of devastating consequences for patients and their families.
