The SILVER-AP study]. / Perfil clínico de pacientes con fibrilación auricular tratados con anticoagulantes orales de acción directa atendidos en atención primaria. Estudio SILVER-AP.

ABSTRACT

OBJECTIVE: To analyse the clinical characteristics and management of patients with non-valvular atrial fibrillation (NVAF) treated with direct oral anticoagulants (DOAC). DESIGN: Observational, cross-sectional and multicentre study. LOCATION Autonomous Communities in which the general practitioner can prescribe DOAC (n=9). PARTICIPANTS: The study included a total of 790 patients on chronic treatment with anticoagulants, and on whom therapy was changed, as well as being currently on treatment with DOAC for at least for 3 months. MAIN MEASURES: A record was made of the sociodemographic and clinical management date. RESULTS: Mean age was 78.6±8.4 years, and 50.5% of patients were men. Mean CHADS2 score was 2.6±1.2, mean CHA2DS2-VASc score was 4.3±1.6, and the mean HAS-BLED score was 2.3±1.0. Mean duration of treatment with DOAC was 15.8±12.5 months. Rivaroxaban was the DOAC most frequently prescribed (57.8%), followed by dabigatran (23.7%), and apixaban (18.5%). Of the patients receiving rivaroxaban, 70.2% were taking the dose of 20mg/daily. Of the patients receiving dabigatran, 41.7% were taking the dose of 150mg twice daily, and in the case of apixaban, 56.2% were taking the dose of 5mg twice daily. Satisfaction (ACTS Burdens scale 52.0±7.2 and ACTS Benefits scale 12.1±2.2), and therapeutic adherence (97.8% of patients took their medication regularly) with DOAC were high. CONCLUSIONS: Patients treated with DOAC in Spain have a high thromboembolic risk. A significant proportion of patients receive a lower dose of DOAC than that recommended according to their clinical profile. Satisfaction and medication adherence are high.
