BACKGROUND AND OBJECTIVE

To evaluate the adherence to the recommendations in clinical practice performed by the Therapeutic Positioning Report (TPR) of the Spanish Agency of Medicines and Sanitary Products about the treatment with oral anticoagulants in patients aged≥75 years old with nonvalvular atrial fibrillation (NVAF) treated in Internal Medicine departments in Spain.

PATIENTS AND METHODS

Observational, cross-sectional and multicenter study in which 837 patients aged≥75 years old with NVAF, with stable treatment with oral anticoagulants at least 3 months before inclusion, and that had started treatment with oral anticoagulants before the inclusion period were included.

RESULTS

Mean age was 83.0±5.0 years old, mean CHADS score 3.2±1.2, mean CHADS-VASc score 5.0±1.4, and mean HAS-BLED score 2.1±0.9. A percentage of 70.8 of patients were treated with vitamin K antagonists (VKA) and the rest of patients with direct oral anticoagulants (DOACs). A percentage of 65.6 of patients treated with VKA did not follow the recommendations made by the TPR compared with 43.0% of patients treated with DOACs (P<.0001). In the case of VKA, the main reason for being considered as not appropriate according to the TPR was having poor control of anticoagulation and not switching to DOACs, whereas in the case of DOACs, it was not receiving the adequate dose according to the TPR.

CONCLUSIONS

In a high proportion of anticoagulated elderly patients with NVAF in Spain, the recommendations performed by the TPR are not followed, particularly with VKA, since patients are not switched to DOACs despite time in therapeutic range.
