BACKGROUND
The Beliefs about Medicines Questionnaire (BMQ) is a validated tool that has been correlated with medication adherence.
OBJECTIVES
To determine patients' beliefs about their heart failure (HF) medications and their self-reported adherence.
METHODS
In this prospective cross-sectional survey of community-dwelling adult patients with any type of HF, beliefs were assessed using the BMQ. Self-reported adherence was assessed using the 5-item Medication Adherence Report Scale (MARS-5). Data were collected between January and May 2024. The primary outcome was the BMQ necessity-concerns differential (NCD).
RESULTS
Thirty-five patients completed the survey. The mean age was 63.9 years, and 22 (63%) of the patients were women. Thirteen patients (37%) self-reported having HF with reduced ejection fraction. The mean NCD was 7.8 (range -20 to +20). The mean BMQ subscale scores were as follows: general-harm, 8.8 out of 25; general-overuse, 8.1 out of 15; specific-necessity, 20.7 out of 25; and specific-concerns, 12.9 out of 25. The mean MARS-5 score was 22.3 out of 25.
CONCLUSIONS
The positive value for mean NCD indicated that patients' beliefs about the necessity of their HF medications exceeded their concerns. Self-reported adherence was high.
背景
药物信念问卷（BMQ）是一种经过验证的工具，已被证明与药物依从性相关。
目的
确定患者对其心力衰竭（HF）药物的信念以及他们自我报告的依从性。
方法
在这项针对社区居住的任何类型HF成年患者的前瞻性横断面调查中，使用BMQ评估信念。使用5项药物依从性报告量表（MARS-5）评估自我报告的依从性。数据于2024年1月至5月收集。主要结局是BMQ必要性-担忧差异（NCD）。
结果
35名患者完成了调查。平均年龄为63.9岁，22名（63%）患者为女性。13名患者（37%）自我报告射血分数降低的心力衰竭。平均NCD为7.8（范围-20至+20）。BMQ子量表平均得分如下：一般危害，25分中得8.8分；一般过度使用，15分中得8.1分；特定必要性，25分中得20.7分；特定担忧，25分中得12.9分。MARS-5平均得分为25分中的22.3分。
结论
平均NCD的正值表明患者对其HF药物必要性的信念超过了他们的担忧。自我报告的依从性较高。
