Abstract
Objective: To evaluate medication knowledge and adherence in oral anticoagulant-taking outpatients. Subject and method: A cross-sectional descriptive study was conducted on 152 outpatients using vitamin K antagonists (VKA) or direct oral anticoagulants (DOAC) at 108 Military Central Hospital from December 2023 to February 2024. The study evaluated knowledge and adherence to anticoagulants by utilizing AKT and GMAS questionnaires, which had been already translated, validated, and culturally adapted in Vietnam. Result: The average age was 70.9 ± 8.1 years. Anticoagulation was indicated primarily (94.1%) in atrial fibrillation. The standardized knowledge score of the entire sample was 43.2%. The DOAC group had a better score of 44.1% compared to the VKA group with a score of 36.5%. Only 3.9% of patients were classified as having “Good” knowledge. Regarding adherence, a significant majority of patients (88.8%) demonstrated a “High” level of adherence to anticoagulant use. The rate in the DOAC group was 88.1%, which was lower than the rate in the VKA group at 94.1%. Conclusion: The study identified a deficiency in anticoagulant use knowledge among outpatients; nevertheless, adherence to anticoagulants was satisfactory. Efficient strategies are required to increase knowledge on anticoagulants, therefore leading to the optimization of anticoagulant therapy and enhancement of treatment quality.
