Abstract
A trial fibrillation (AF) increases cardio-embolic stroke risk, yet AF diagnosis and subsequent prophylactic anticoagulant prescription rates are suboptimal globally. This project aimed to increase AF diagnosis and subsequent anticoagulation prescription rates in East Midlands Clinical Commissioning Groups (CCGs). This service improvement evaluation of the East Midlands AF Advance programme investigated the implementation of mobile AF detection devices (Kardia, AliveCor) into primary-care practices within East Midlands CCGs, along with audit tools and clinician upskilling workshops designed to increase AF diagnosis and anticoagulation prescription rates. AF prevalence and prescription data were collected quarterly from July to September (Q3) 2017/18 to April to June/July to September (Q2/3) 2018/19. AF prevalence increased from 1.9% (22,975 diagnoses) in Q3 2017/18 to 2.4% (24,246 diagnoses) in Q2 2018/19 (p=0.026), while the percentage of high-risk AF patients receiving anticoagulants increased from 80.5% in Q3 2017/18 to 86.9% in Q3 2018/19 (p=0.57), surpassing the Public Health England 2019 target of 85%. The East Midlands AF Advance programme increased AF diagnosis and anticoagulation rates, which is expected to be of significant clinical benefit. The mobile AF detection devices provide a more practical alternative to traditional 12-lead electrocardiograms (ECGs) and should be incorporated into routine clinical practice for opportunistic AF detection, in combination with medication reviews to increase anticoagulant prescription.
