A patient's knowledge of heart failure (HF) is associated with better outcomes. The more information patients have about their illness, the less likely they are to be readmitted to the hospital. Such knowledge includes the cause, symptoms, probable duration, and expected evolution of the clinical picture. In Portugal, a tool for testing patient knowledge is an unmet need. Therefore, this study aimed to adapt and test the Chronic Heart Failure Knowledge Questionnaire (KQCHF) for the Portuguese context.
This work includes three cross-sectional studies. In Study 1, subjects were divided between before and after receiving information about HF. In Study 2, participants answered the questionnaire before and after reading the brochure. In Study 3, KQCHF was applied to patients with HF. Studies 1 and 2 were carried out in the general population. Study 3 was carried out with HF outpatients. Convenience sampling was applied to participants in the three studies.
In Study 1 (n = 45), those who received information had better scores (9.2 ± 1.9) than those who did not (6.0 ± 2.3). In Study 2 (n = 21), the scores were higher after reading the brochure (10.4 ± 1.7 vs. 6.5 ± 2.9). In Study 3 (n = 169), women had better scores than men (9.1 ± 2.1 vs. 8.3 ± 2.2, overall: 8.5 ± 2.2), and knowledge was correlated with education (r = .340, p < .001) and age (r = -.170, p = .030).
The Portuguese adaptation of KQCHF captured relevant knowledge about HF and has shown promising results for clinical and research purposes. The questionnaire can be useful in assessing HF patients' knowledge of their disease and as a basis for the implementation of general and personalised educational strategies to improve HF knowledge and, therefore, promote health literacy and self-care.
患者对心力衰竭（HF）的了解与更好的预后相关。患者对疾病的了解越多，他们再次住院的可能性就越小。这种知识包括疾病的病因、症状、可能的持续时间以及临床症状的预期演变。在葡萄牙，测试患者知识的工具是一个未满足的需求。因此，本研究旨在改编并测试慢性心力衰竭知识问卷（KQCHF）在葡萄牙的应用。
这项工作包括三项横断面研究。在研究 1 中，受试者被分为接受 HF 信息前后两组。在研究 2 中，参与者在阅读手册前后回答问卷。在研究 3 中，KQCHF 应用于 HF 门诊患者。研究 1 和 2 在普通人群中进行。研究 3 在 HF 门诊患者中进行。在三项研究中均采用便利抽样方法选择参与者。
在研究 1（n=45）中，接受信息的患者得分（9.2±1.9）优于未接受信息的患者（6.0±2.3）。在研究 2（n=21）中，阅读手册后得分更高（10.4±1.7 vs. 6.5±2.9）。在研究 3（n=169）中，女性的得分高于男性（9.1±2.1 vs. 8.3±2.2，总体：8.5±2.2），知识与教育程度（r=0.340，p<0.001）和年龄（r=-0.170，p=0.030）相关。
KQCHF 的葡萄牙语改编版捕捉了 HF 相关的重要知识，并显示出在临床和研究目的方面的有前途的结果。该问卷可用于评估 HF 患者对其疾病的了解程度，并为实施一般和个性化教育策略提供基础，以提高 HF 知识，从而促进健康素养和自我护理。
