Quality indicators in the management of atrial fibrillation: the BALKAN-AF survey

Abstract

Background: The implementation of quality indicators in the atrial fibrillation (AF) care should be considered to improve quality of management and patient outcome. Methods: In the post-hoc analysis of the BALKAN-AF dataset, we assessed concordance with quality indicators for AF management. Available domains for AF management [patient assessment (baseline), anticoagulation, rate control strategy, rhythm control strategy and risk factor management] were identified and assessed at baseline visit. Results: Among 132 patients with a CHA2DS2-VASc score of 0 (men) or 1 (women), 75 (56.8%) were prescribed oral anticoagulation (OAC). Of 2539 patients with a CHA2DS2-VASc score ≥ 1 for men and ≥ 2 for women, 1890 (74.4%) were prescribed OAC. Among 1088 patients with permanent AF, 110 (10.1%) individuals were prescribed antiarrhythmic drugs (AADs). Of 1616 patients with structural heart disease, 37 (2.2%) were prescribed class IC AADs. Of 1624 patients with paroxysmal or persistent AF, 59 (3.6%) were offered catheter ablation. Among 2712 AF patients, 2121 (78.2%) had hypertension, 671 (24.7%) were obese, 53 (2.0%) had obstructive sleep apnoea, 110 (4.0%) had alcohol abuse and 340 (12.5%) were smokers. Conclusions: In the BALKAN-AF cohort, the use of OAC for stroke prevention was poorly associated with patients stroke risk. The use of AADs in patients with permanent AF was low. The prescription of class IC AADs to patients with structural heart disease was infrequent. A large proportion of AF patients had their modifiable risk factors identified. © 2021
