Impact of atrial fibrillation and anticoagulation on the risk of death, thromboembolic disease and bleeding in patients with COVID-19: the ACO-VID Registry
CONCLUSIONS: Among patients hospitalized with COVID-19, patients with AF were older, had more comorbidities and had a higher risk of major bleeding. Age and elevated transaminases during hospitalization, but not AF nor anticoagulant treatment increased the risk of all-cause death.PMID:37189306 | DOI:10.1080/03007995.2023.2204009

Risk of stroke/systemic embolism, major bleeding and associated costs in non-valvular atrial fibrillation patients who initiated apixaban, dabigatran, or rivaroxaban compared with warfarin in the United States Medicare population: updated analysis
CONCLUSIONS: This real-world analysis showed DOACs to be associated with lower risk of stroke/SE and major bleeding, and lower medical costs compared to warfarin. Among them, only apixaban appears to be associated with a significantly lower risk of all three outcomes collectively: stroke/SE, major bleeding, and lower related medical costs compared to warfarin.PMID:35993487 | DOI:10.1080/03007995.2022.2115772

Impact of the COVID-19 pandemic on England's national prescriptions of oral vitamin K antagonist (VKA) and direct-acting oral anticoagulants (DOACs): An interrupted time series analysis (January 2019 - February 2021)
Conclusion: The overall oral anticoagulants use in this period was lower than expected, indicating a medical needs gap, possibly due to adherence issues. The potential clinical and logistical consequences warrant further study to identify contributing factors and mitigate avoidable risks.PMID:35582854 | DOI:10.1080/03007995.2022.2078100

Risk of stroke and other thromboembolic complications after interruption of DOAC therapy compared with warfarin therapy in patients with atrial fibrillation: a retrospective cohort analysis
This study did not find a significant difference in the complication rate after interruption of DOAC therapy compared with interruption of warfarin therapy in hospitalized patients with a high risk of thromboembolism.

Effectiveness and Safety of Non-Vitamin K Antagonist Oral Anticoagulants in Asian Patients with Atrial Fibrillation and Valvular Heart Disease.
CONCLUSIONS: NOACs had a comparable risk of ischemic stroke and bleeding in patients with AF and VHD, and reduced the risk of venous thromboembolism, intracranial hemorrhage, and mortality, compared to warfarin. Therefore, NOAC is an effective and safe alternative to warfarin in these patients. PMID: 33538623 [PubMed - as supplied by publisher]

Minor bleeding in patients with atrial fibrillation using a non-vitamin K antagonist oral anticoagulant.
Conclusion: Our data showed that minor bleeds are common in novel NOAC users, especially when using apixaban and rivaroxaban. In the latter two NOACs, hematoma (bruises) and nose bleeds were more frequently observed and accounted for the difference with dabigatran. Besides type of NOAC, a higher HAS-BLED score and novel anticoagulant drug use were associated with an increased risk of minor bleeding. PMID: 32573287 [PubMed - as supplied by publisher]

Reasons for discontinuation of novel oral anticoagulant therapy in patients with atrial fibrillation.
Conclusion: DOAC discontinuation rates varied significantly and appeared related to drug-specific side effects, patient-initiated discontinuation, and bleeding. We observed longer-term administration of apixaban, suggesting that this drug is better tolerated than dabigatran or rivaroxaban. PMID: 32011180 [PubMed - as supplied by publisher]

Real-life behaviour of direct oral anticoagulants in a Spanish cohort with nonvalvular atrial fibrillation: Refase Registry.
CONCLUSION: Our results of safety and efficacy are very similar to those of other previously published national registries. There were no differences among the different types of DOAC regarding outcomes. However, it was found that people taking the adjusted dose of the drug seemed to have a higher risk of death. A non-negligible proportion of patients received DOAC doses inconsistent with labelling (mostly underdose). PMID: 31335222 [PubMed - as supplied by publisher]

Impact of methodological choices on a meta-analysis of real-world evidence comparing non-vitamin K antagonist oral anticoagulants with vitamin K antagonists for the treatment of patients with non-valvular atrial fibrillation.
Conclusions Sensitivity analyses showed the impact of similar assumptions was different depending on the outcome, and the drug considered. The development of recommendations and guidelines for the inclusion of RWE in meta-analyses could prove useful in evaluating the effectiveness of health care interventions.
