Atrial fibrillation (AF) is one of the most common cardiac arrhythmia diseases [As China progressed in primary care and implemented a two-way referral system, most patients with AF would receive antithrombotic medical services in community health centers in the future. The movement also corresponded with the view of “integrated care and stratified therapy” highlighted by some scholars, which meant that patients could get access to comprehensive management in primary care, such as risk assessment, AF treatment, international normalized ratio (INR) monitoring, health education, and treatment of comorbidity diseases, with superior hospitals responsible for the treatment of complications, emergencies, and operations [CDSSs, to some extent, are typical examples of artificial intelligence applications in healthcare settings, in which they are supported by computer algorithms. They can help primary care providers quickly make individualized and correct clinical decisions by combining patient data with guidelines in short consultations [We evaluated an AF antithrombotic management-associated CDSS, specifically designed for GPs, and wanted to carry out a cluster-randomized controlled trial to confirm its utility. This study was a prospective cohort study with a semistructured interview and a feasibility study for the cluster-randomized controlled trial. We aimed to primarily investigate the effect of the CDSS in community health centers in Shanghai, China, on the proportion of patients prescribed guideline-directed antithrombotic therapy. We also sought to evaluate the GP's acceptance of the CDSS who worked in the atrial fibrillation (AF) special consulting room of the CDSS group.
