Filter by:The rhythm disorders of Atrial Fibrillation (AF) require continuous treatment with anticoagulants to prevent stroke. The introduction of direct oral anticoagulants (DOACs) quickly supplanted the administration of anti-vitamin K (AVK) which presented an elevated risk of hemorrhage. However, the adherence of the treatments by the OAD is very poor, several studies show that 30 to 50% of the patients fail to adhere to their treatment very soon after starting it. In a recent study, in the United States, using data collected between 2010 and 2014 in more than 60,000 patients with AF, Yao et al show that less than 50% of patients can be considered "adherent". They conclude in this study that adherence to anticoagulation is low in practice, although it may be slightly improved with DOACs. More recently a meta-analysis shows that 66% of patient treated by DOACs were considered adherent (PDC > 80 %). In addition, therapeutic adherence seems to be essential in patients with a CHA2DS2-VASc score ≥2. Indeed improving adherence reduces the risk of stroke occurrence. The investigators propose to evaluate during an interview in the pharmacy, the adherence of ambulatory patients (at the time of their renewal of treatment at the pharmacy) by the "Proportion of Days Covered" (PDC) of the treatment by AOD, and by a simplified questionnaire and to define a profile of patients treated for AF at risk of nonadherence to AOD (PDC adherence prediction score). The investigators perform an observational, prospective multicenter study , in which patients adherence will be quantified in a standardized method.
The outcomes regiStry for non-vitamin k antagonist oral anticoagUlants treatmeNt in variouS tHrombotIc dIseases for better cliNical practicE (SUNSHINE) is a multicenter, prospective, observational non-interventional inpatient/outpatient disease registry to assess the utilization of Non-vitamin k antagonist oral anticoagulants (NOACs), and associated outcomes. The SUNSHINE registry will focus on the collection and analysis of observational data in medical records from hospital information system (HIS) to evaluate the outcomes related with these NOACs when applied in extensive patient populations outside of clinical research studies. The registry will also allow for mainly combining the atrial fibrillation (AF) and venous thromboembolism (VTE) databases. In brief, the SUNSHINE registry will provide important information on the outcomes of NOACs in routine practice and gather further information on its safety and effectiveness.
