The Atrial Fibrillation Better Care (ABC) pathway is such an integrated care approach, recommended in guidelines. The aim of this service evaluation study was to evaluate the impact of implementing the ABC pathway in Iranian population.
In this prospective longitudinal cohort study, consecutive patients with a diagnosis of AF were initially evaluated. Patients at baseline were evaluated in hence of adherence to ABC pathway strategy. After study enrolment, first and second follow-up service evaluations were conducted at 6 and 12 months, respectively.
The use of vitamin K antagonists (VKA) decreased from 25.1 % at enrolment to 13.8 % at follow-up; instead, non-VKA oral anticoagulants (NOAC) utilization increased from 40.0 % to 86.1 %, while antiplatelet treatment decreased from 34.9 % to 0 %. Use of antihypertensive drugs, ARBs, diuretics, and statins increased after implementation of the ABC pathway. Implementation of the ABC pathway approach led to a decrease in the occurrence of stroke/TIA (from 6.3 % to 2.2 %, p = 0.002), systemic thromboembolism (from 1.4 % to 0.0 %, p = 0.04), nose bleeds (from 0.8 % to 0.6 %, p = 0.04), skin bruising (from 1.2 % to 0.0 %, p = 0.002), and heart failure (from 7.7 % to 4.7 %, p = 0.04). The proportion of patients in EHRA Class I-II increased from 93.3 % at enrolment to 98.1 % at follow-up.
In this first study from a Middle East population, compliance with ABC pathway strategy in the management of AF was associated with optimization of management and general improvements in patient outcomes during follow-up.
