Key result

DUTCH-AF registry evaluates the clinical impact of oral anticoagulation non-adherence in newly diagnosed AF.

  • n=6,000

Why the study?

Prospective registries with longitudinal data on anticoagulant therapy, treatment adherence, and adverse events in practice-based cohorts were lacking, particularly for NOACs.

What is the effect of non-adherence and non-persistence of anticoagulation therapy on clinical adverse events in patients with newly diagnosed non-valvular atrial fibrillation?

Population

Target of 6000 patients with newly diagnosed non-valvular AF across the Netherlands

Comparison

Adherence and persistence to anticoagulant therapy in routine clinical care

Design

Nationwide prospective registry programme and observational study

Follow-up

At least 2 years

What is the effect of non-adherence and non-persistence of anticoagulation therapy on clinical adverse events in patients with newly diagnosed non-valvular atrial fibrillation?

P
Population
A target of 6,000 adults with newly diagnosed non-valvular atrial fibrillation in the Netherlands, to be followed for at least 2 years to assess anticoagulation adherence and outcomes.
E
Exposure
Oral antithrombotic treatment (including non-vitamin K oral anticoagulants) in routine clinical care
O
Outcome
Clinical adverse events (e.g., bleeding and stroke) associated with non-adherence and non-persistence of anticoagulation therapyhard clinical

The DUTCH-AF registry aims to provide longitudinal data on anticoagulant therapy adherence, persistence, and associated adverse events in a nationwide cohort of patients with newly diagnosed non-valvular atrial fibrillation.

Limitations

  • Confounding by indication cannot be entirely captured in the minimal data sheet
  • Recall bias can occur during the telephone conversation with the patient as part of follow-up
  • Risk of misclassification
  • Potential disproportionate enrollment from primary and secondary/tertiary care could limit extrapolation and generalizability
  • Concise echocardiographic data were not registered to minimize registration burden

Cite This Study

Chu et al. (2020) conducted an observational in Atrial fibrillation (n=6,000). Oral anticoagulation therapy (adherence and persistence) vs. Non-adherence and non-persistence was evaluated on Thromboembolic and bleeding events, changes in antithrombotic therapy, and hospital admissions. The DUTCH-AF registry is a prospective nationwide observational study designed to evaluate the clinical impact of non-adherence and non-persistence to oral anticoagulation therapy in 6,000 patients with newly diagnosed atrial fibrillation.
