Abstract
The Atrial fibrillation Better Care (ABC) pathway provides a framework for holistic care management of atrial fibrillation (AF) patients. This study aimed to determine the impact of changes in compliance to ABC pathway management on clinical outcomes.
This is a prospective multicenter AF registry. Patients with non-valvular AF were enrolled and followed-up for 3 years. Baseline and follow-up compliance to the ABC pathway was assessed. The main outcomes were all-cause death, ischaemic stroke/systemic embolism, major bleeding, and heart failure. There studied 3096 patients (mean age 67.6 ± 11.1 years, 41.8% female). Patients were categorized into four groups: Group 1: ABC compliant at baseline and 1 year [n = 1022 (33.0%)]; Group 2: ABC non-compliant at baseline but compliant at 1 year [n = 307 (9.9%)]; Group 3: ABC compliant at baseline and non-compliant at 1 year [n = 312 (10.1%)]; and Group 4: ABC non-compliant at baseline and also at 1 year [n = 1455 (47.0%)]. The incidence rates [95% confidence intervals (CI)] of the composite outcome for Group 1–4 were 5.56 (4.54–6.74), 7.42 (5.35–10.03), 9.74 (7.31–12.70), and 11.57 (10.28–12.97), respectively. With Group 1 as a reference, Group 2–4 had hazard ratios (95% CI) of the composite outcome of 1.32 (0.92–1.89), 1.75 (1.26–2.43), and 2.07 (1.65–2.59), respectively.
Re-evaluation of compliance status of the ABC pathway management is needed to optimize integrated care management and improve clinical outcomes. AF patients who were ABC pathway compliant at baseline and also at follow-up had the best clinical outcomes.
