Abstract

Background Oral anticoagulants are widely used for treatment and prevention of thromboembolic diseases. We set up a pharmaceutical counseling program for both direct oral anticoagulant and vitamin K antagonist drugs in our hospital in 2015. Objective Evaluate patient satisfaction and the evolution of their knowledge throughout the pharmaceutical counseling program on anticoagulants and identify knowledge variability factors. Setting Cardiology Inpatient Unit from the University Antoine Béclère Hospital, France. Methods Evaluation was based on data collection of patients surveyed between 2015 and 2018. Inpatients in the cardiology department on oral anticoagulants were eligible. The learning process was designed to enhance patient knowledge and understanding based on 10 cognitive or self-management skills, relating to the optimization of oral anticoagulant therapy management. It consisted in 2 face-to-face interviews during hospitalization and 2 additional phone interviews one and six months after discharge. The median patient score was evaluated at each step of the process as well as the mean score for each item from the global population. A sub-analysis was run on the less well-acquired skills in order to identify risk factors for limited knowledge. The association between those factors and the level of knowledge (score ≥ 7 or < 7) was assessed using Chi square test followed by multivariate analysis. Main outcome measure Patient knowledge of anticoagulation therapy depending on specific factors. Results Of the 880 patients eligible for pharmaceutical counseling, 319 entered the process and 102 completed it. Median knowledge scores were 8/10 and 9/10 after the first and the final interviews respectively with a significant improvement (p = 0.0003). The least well-acquired items at each step were surveillance and under-dosing management. The sub-analysis showed the use of vitamin K antagonist to be linked to an enhanced understanding related to treatment surveillance (p = 0.029). Patients suffering from atrial fibrillation were found to have a worse understanding of under-dosing management (p = 0.013). Finally, patients evaluated the process as helpful and suitable for their conditions. Conclusion Pharmaceutical counseling is appropriate for patients, improving and maintaining knowledge of oral anticoagulants. Our evaluation highlights the need to focus on patient-specific profiles to reach a satisfactory level of knowledge.
