Insights
Many patients with non-valvular atrial fibrillation (NVAF) in Spain have poor anticoagulation control with vitamin K antagonists (VKA). Direct oral anticoagulants (DOACs) offer better control and reduced bleeding risk, but barriers to their use persist.
Area of Science:
- Cardiology
- Pharmacology
- Primary Care Medicine
Background:
- Suboptimal anticoagulation control affects approximately 40% of patients with non-valvular atrial fibrillation (NVAF) on vitamin K antagonists (VKA) in Spanish primary care.
- This highlights a critical need to evaluate current anticoagulant practices and identify areas for improvement.
Purpose of the Study:
- To analyze the current use of VKAs and non-vitamin K antagonist oral anticoagulants (NOACs) in NVAF patients within Spanish primary care.
- To identify challenges and controversies associated with oral anticoagulant use in this population.
Main Methods:
- An online survey was distributed to experts, employing a two-round modified Delphi approach.
- The survey covered various aspects of oral anticoagulant use in NVAF, with results compiled into practical guidelines.
Main Results:
- Consensus was reached on 62% of survey items, confirming poor INR control in many VKA-treated patients.
- Experts identified that a significant number of patients who could benefit from NOACs are not receiving them.
- NOAC use was associated with improved anticoagulation control and reduced risk of severe/intracranial hemorrhage, though barriers like administrative issues, knowledge gaps, and cost exist.
Conclusions:
- The ACTUA study reveals significant controversies in oral anticoagulant use for NVAF in Spanish primary care.
- Consensus-based recommendations were developed to potentially enhance the appropriate use of these medications.
Objectives:
Approximately 40% of patients with non-valvular auricular fibrillation (NVAF) who receive vitamin K antagonists (VKA) in Primary Care in Spain have poor anticoagulation control. The objective of the study Actuación en antiCoagulación, Tratamiento y Uso de anticoagulantes orales de acción directa (ACOD) en Atención primaria (ACTUA) (Action in Coagulation, Treatment and Use of direct oral anticoagulants [DOACs]) in Primary Care) was to analyse the current situation regarding the use of VKA and non-vitamin K antagonist oral anticoagulants (NOACs) in patients with NVAF in Primary Care in Spain and the possible issues arising from it.
Patients And Methods:
An online survey was created covering various aspects of the use of oral anticoagulants in NAFV. A two-round modified Delphi approach was used. Results were compiled as a set of practical guidelines.
Results:
Forty-four experts responded to the survey. Consensus was reached in 62% (37/60) of the items. Experts concluded that a considerable number of patients with NVAF who receive VKA do not have a well-controlled INR and that a substantial group of patients who could benefit from being treated with NOACs do not receive them. The use of NOACs increases the probability of having good anticoagulation control and decreases the risk of severe and intracranial haemorrhage. Current limitations to the use of NOACs include administrative barriers, insufficient knowledge about the benefits and risks of NOACs, limited experience of doctors in using them, and their price. Renal insufficiency influences the choice of a particular anticoagulant.
Conclusions:
The ACTUA study highlights the existing controversies about the use of oral anticoagulants for the treatment of NVAF in Primary Care in Spain, and provides consensus recommendations that may help to improve the use of these medications.
