ABSTRACT
OBJECTIVE: During the first wave of the SARS-CoV-2 pandemic, management of anticoagulation therapy in hospitalized patients with atrial fibrillation (AF) was simplified to low-molecular-weight heparin (LMWH) followed by oral anticoagulation, mainly owing to the risk of drug-drug interactions. However, not all oral anticoagulants carry the same risk. METHODS: Observational, retrospective, and multicenter study that consecutively included hospitalized patients with AF anticoagulated with LMWH followed by oral anticoagulation or edoxaban concomitantly with empirical COVID-19 therapy. Time-to-event (mortality, total bleeds, and admissions to ICU) curves, using an unadjusted Kaplan-Meier method and Cox regression model adjusted for potential confounders were constructed. RESULTS: A total of 232 patients were included (80.3 ± 7.7 years, 50.0% men, CHA2DS2-VASc 4.1 ± 1.4; HAS-BLED 2.6 ± 1.0). During hospitalization, patients were taking azithromycin (98.7%), hydroxychloroquine (89.7%), and ritonavir/lopinavir (81.5%). The mean length of hospital stay was 14.6 ± 7.2 days, and total follow-up was 31.6 ± 13.4 days; 12.9% of patients required admission to ICU, 18.5% died, and 9.9% had a bleeding complication (34.8% major bleeding). Length of hospital stay was longer in patients taking LMWH (16.0 ± 7.7 vs 13.3 ± 6.5 days; P = .005), but mortality and total bleeds were similar in patients treated with edoxaban and those treated with LMWH followed by oral anticoagulation. CONCLUSIONS: Mortality rates, arterial and venous thromboembolic complications, and bleeds did not significantly differ between AF patients receiving anticoagulation therapy with edoxaban or LMWH followed by oral anticoagulation. However, the duration of hospitalization was significantly lower with edoxaban. Edoxaban had a similar therapeutic profile to LMWH followed by oral anticoagulation and may provide additional benefits.

Antecedentes y objetivos: En los últimos años los anticoagulantes orales directos (ACOD) se han convertido en una alternativa a los antagonistas de la vitamina K (AVK) para la prevención del ictus y embolia sistémica en pacientes con fibrilación auricular no valvular (FANV), así como para la prevención y tratamiento de la trombosis venosa profunda. Los ensayos clínicos han demostrado la no inferioridad y la potencial superioridad en comparación con la warfarina, lo cual permite ampliar las opciones de anticoagulación. En nuestro medio, las Unidades de Tratamiento Anticoagulante (UTA) y los Centros de Atención Primaria (CAP) son los encargados de la educación, seguimiento, control de adherencia y del manejo en situaciones especiales de los pacientes anticoagulados. Estas consideraciones han motivado la preparación del presente documento de consenso, que tiene como objetivo establecer recomendaciones que incorporen los hallazgos de la investigación científica a la práctica clínica para mejorar la calidad asistencial en el ámbito de la anticoagulación. Material y métodos: Un grupo de expertos del Grupo Catalán de Trombosis (TROMBOC@T) ha revisado la bibliografía publicada entre 2007 y 2016 para poder establecer recomendaciones basadas en la evidencia clínica. Resultados: Como resultado del proyecto se han establecido un conjunto de recomendaciones de carácter práctico que facilitarán el tratamiento, educación, seguimiento y manejo en situaciones especiales de los pacientes anticoagulados con ACOD. Conclusiones: El aumento progresivo del uso de los ACOD requiere establecer y homogeneizar las directrices de actuación clínica en el paciente anticoagulado con estos antitrombóticos tanto en las UTA como en los CAP
Background and objectives: In recent years, direct oral anticoagulants (DOACs) have become an alternative to vitamin K antagonists (VKA) for the prevention of stroke and systemic embolism in patients with non-valvular atrial fibrillation (NVAF) as well as for prevention and treatment of deep venous thrombosis. Pivotal trials have demonstrated non-inferiority and potential superiority compared to warfarin, which increases the options of anticoagulant treatment. In our setting, the Anticoagulant Treatment Units (ATUs) and Primary Care Centres (PCCs) play an important role in the education, follow-up, adherence control and management in special situations of anticoagulated patients. These considerations have motivated us to elaborate the present consensus document that aims to establish clear recommendations that incorporate the findings of scientific research into clinical practice to improve the quality of care in the field of anticoagulation. Material and methods: A group of experts from the Catalan Thrombosis Group (TROMBOC@T) reviewed all published literature from 2009 to 2016, in order to provide recommendations based on clinical evidence. Results: As a result of the project, a set of practical recommendations have been established that will facilitate treatment, education, follow-up and management in special situations of anticoagulated patients with ACODs. Conclusions: Progressive increase in the use of DOACs calls for measures to establish and homogenise clinical management guidelines for patients anticoagulated with DOACs in ATUs and PCCs
