Brief Summary

Atrial fibrillation (AF) is the most common cardiac arrhythmia and increases the risk of ischemic stroke 4-5-fold. The prevention of complications is based on oral or antiplatelet anticoagulant treatment. The first choice of anticoagulant therapy (AT) is the vitamin K antagonist (VKA). Contraindication to VKA or poor control of the International Normalized Ratio leads to the administration of direct-acting oral anticoagulants (DOACs). There is a trend towards inadequate AT in non-valvular AF (NVAF) patients. The Objective of the study is evaluate the impact of the implementation of a decision support tool linked to digital clinical history on the adequacy of AT, the incidence of complications and the mortality in patients with NVAF in primary health care of the Catalan Institute of Health (ICS).

Outcome Measures

Primary Outcomes (4)

  • Incidence rate of Thromboembolic events

    Thromboembolic events: acute myocardial infarction or angina, ischemic stroke, peripheral embolism or transient ischemic attack (TIA)

    Two years after the beginning of the intervention

  • Incidence rate of Hemorrhagic events

    Hemorrhagic events: intracranial hemorrhage and gastrointestinal hemorrhage

    Two years after the beginning of the intervention

  • Incidence rate of mortality

    All-cause mortality

    Two years after the beginning of the intervention

  • Adequacy of anticoagulant treatment

    This variable encompasses the adequacy of the anticoagulant treatment, taking into account if an adequate change has occurred or not. 0 = No adequate change (when an inadequate change has been produced or when an inadequate treatment has been maintained) 1 = adequate change (when an adequate change has been produced or when an adequate treatment has been maintained) The adequacy of the anticoagulant therapy in patients with NVAF will be based on the fulfillment of the criteria of the Ministry of Health, Social Services and Equality of Spain, 2016\* \* Ministry of Health, Social Services and Equality. Criteria and recommendations for the use of direct oral anticoagulants (ACOD) in the prevention of stroke and systemic embolism in patients with non-valvular atrial fibrillation. 2016. available in: https://www.aemps.gob.es/medicamentosUsoHumano/informesPublicos/docs/criterios-anticoagulantes-orales.pdf

Interventions

CDS-NVAFDEVICE

The CDS-NVAF is intended for patients diagnosed with NVAF and treated with VKA. This tool calculates the time in the therapeutic range (TTR) using the Rosendaal method considering the last International Normalized Ratio (INR) data. The INR data are found in the clinical history of NVAF patients. The CDS-NVAF will be activated when the physician introduces the last INR value. At this time the TTR will be calculated automatically. If the TTR value is \< 65%, a pop up screen with a warning text will open suggesting a change to DOAC therapy. The physician can decide whether to change or not the previous prescription. If the TTR value in \> 65% the pop up screen will not appear. The TTR value will remain registered on the screen of the follow up of oral anticoagulant use and can be consulted in future queries. The diffusion of the CDS-NVAF will be made by an announcement on the first day of the intervention when the health care professional opens the electronic clinical history.
