Background: The Jessa Atrial Fibrillation Knowledge Questionnaire (JAKQ) was successfully used to assess knowledge gaps in patients with atrial fibrillation (AF).

Aims: To evaluate the regional differences among Polish patients in their awareness of AF diagnosis and oral anticoagulation use.

Methods: A total of 1583 patients with AF at a median (IQR) age of 72 (66–79) years completed the JAKQ in 3 cardiology centers (center I, Kraków; center II, Toruń; center III, Kielce) from January 2017 to June 2018. The final analysis included 1525 patients, 32.9% were on vitamin K antagonists (VKAs) and 67.1% on non-VKA oral anticoagulants (NOACs), that is, rivaroxaban and dabigatran (28.9% each), and apixaban (9.3%).

Results: The mean (SD) score on the JAKQ was 55.5% (18.4%) with better results among patients on VKAs compared with NOACs (58% [18.3%] vs 54.3% [18.4%]; P = 0.0002) with time from AF diagnosis more than 12 months (57.4% [17.5%] vs 50% [19.9%]; P < 0.0001). There was a significant difference in the knowledge scores between the 3 centers (I, 59.5%; II, 48.5%; III, 54.3%; P < 0.0001). In all centers the number of correct answers correlated inversely with patient’s age (r = –0.20; P < 0.0001). NOACs were more frequently used in center III. The percentage of correct responses was lower in patients on reduced NOAC doses (35.4% of patients on NOACs), compared with the full-dose NOAC groups in center I (56.9% vs 62.5%; P = 0.012) and II (48.1% vs 56.2%; P = 0.003).

Conclusions: Patients from a high-volume academic center showed better knowledge than their peers from district hospitals. There are large regional differences in prescription patterns of oral anticoagulants, including the preferred NOAC.
