Background Knowledge about oral anticoagulant treatment can impact treatment outcomes in patients with atrial fibrillation. However, evidence is scarce regarding the knowledge of oral anticoagulants among Saudi patients with atrial fibrillation. Hence, this study aimed to assess the level of anticoagulation knowledge among patients with atrial fibrillation taking oral anticoagulants. Methodology A survey using a cross-sectional study design was conducted among patients with a confirmed diagnosis of atrial fibrillation in a tertiary care setting. The Oral Anticoagulation Knowledge Tool (AKT), a 33-item, self-administered questionnaire, was used to assess the knowledge of anticoagulation. Results A total of 290 patients with a median age of 67 years participated in the survey. More than half of those surveyed (56.2%) were females. Overall, 195 (67.2%) patients had an overall adequate anticoagulation knowledge. The median knowledge score of participants on warfarin was significantly higher than those on direct-acting oral anticoagulants ( < 0.001). Only age was found to be a predictor of AKT. Increasing age was associated with fewer odds of adequate AKT. For every one-year increase in age, the knowledge score decreased by 0.08 (95% confidence interval: -0.13 to -0.04). Conclusions This study found significant knowledge gaps among Saudi patients with atrial fibrillation taking oral anticoagulants. Advancing age was inversely associated with oral anticoagulation knowledge.
背景
关于口服抗凝治疗的知识会影响房颤患者的治疗效果。然而，沙特房颤患者对抗凝剂知识的相关证据却很匮乏。因此，本研究旨在评估服用口服抗凝剂的房颤患者的抗凝知识水平。
方法
在一家三级医疗机构中，对确诊为房颤的患者进行了一项采用横断面研究设计的调查。使用《口服抗凝知识工具》（AKT），这是一份有33个项目的自填式问卷，用于评估抗凝知识。
结果
共有290名中位年龄为67岁的患者参与了调查。超过一半（56.2%）的受访者为女性。总体而言，195名（67.2%）患者的抗凝知识总体充足。参与者对华法林的知识得分显著高于对直接口服抗凝剂的得分（<0.001）。仅发现年龄是AKT的一个预测因素。年龄增长与AKT充足的几率降低相关。年龄每增加一岁，知识得分下降0.08（95%置信区间：-0.13至-0.04）。
结论
本研究发现，沙特服用口服抗凝剂的房颤患者存在明显的知识差距。年龄增长与口服抗凝知识呈负相关。
