Brief Summary

Public health surveillance models, previously used for the ongoing detection of occurrence of rare events, could be used to reinforce existing pharmacovigilance systems. These models have not been previously used for Adverse Drug Reaction (ADR) detection in medico-administrative databases. DABISURV research project focuses on a new anticoagulant therapy, dabigatran, launched recently on the French market for atrial fibrillation (AF). This drug is at high risk for severe ADR and requires thus careful pharmacovigilance monitoring. Primary objective is to compare the results of ongoing surveillance models to detect hemorrhages or acute myocardial infarction (AMI) associated with dabigatran, with the results obtained from the analysis of a cohort of patients with AF under the same treatment.

Outcome Measures

Primary Outcomes (1)

  • results of ongoing surveillance models to detect hemorrhages or AMI (in frequency and proportion) associated with dabigatran or VKA for AF in a health database cohort of patients with AF treated by dabigatran or VKA

    Propensity-matching is required for adequate comparison and multivariate regression

    36 months

Study Arms (2)

VKA

First Initiators of VKA for non-valvular atrial fibrilation

Dabigatran

First Initiators of Dabigatran for non-valvular atrial fibrilation

Drug: Dabigatran

Interventions

Healthy VolunteersNo
Age GroupsAdult (18-64), Older Adult (65+)
Sampling MethodProbability Sample
Study Population

Cohort of adult patients diagnosed with AF or atrial flutter and who received at least one prescription of VKA (warfarin /acenocoumarol /fluindion) or dabigatran between 2009 and 2014. As opposed to other countries, in France, warfarin is not the most prescribed VKA for AF.

You may qualify if:

  • Patients with non-valvular atrial fibrillation
  • Patients receiving an first prescription of anticoagulants

You may not qualify if:

  • Patients with valvular atrial fibrillation
