To evaluate the preliminary effectiveness and usability of a novel mobile phone-based self-care intervention (named WithUs) for patients with heart failure (HF).
We conducted a mixed-methods pilot study with group pre-test-post-test design and usability testing. Participants were 26 Korean HF patients (20 men; median age 62 years) who took part in this study after hospital discharge. Data were collected at baseline and after the 24-week intervention, using questionnaires and interviews. The outcome variables were eHealth literacy, disease knowledge, and self-care behaviours. The Wilcoxon signed-rank test was used to compare the pre- and post-intervention results. Thematic analysis was used for analysing qualitative data. The WithUs programme improved the eHealth literacy (P = 0.005), disease knowledge (P < 0.001), and self-care behaviours (P < 0.001) of patients with HF. The median score of total app usability was 4.1 out of 5 (interquartile range = 4.0-5.0). Four themes were identified which complemented the quantitative results. These were increased awareness of the importance of routine self-care behaviours, enhanced motivation toward self-care behaviours, challenges adapting to the new app, and suggestions for improving app adoption.
The app was effective in improving adherence to self-care behaviours, eHealth literacy, and disease knowledge in patients with HF. The usability evaluation results showed that the app is usable and has the potential to support HF patients in self-care. However, the app needs to be modified to improve its adoption.
评估一种新型的基于手机的自我护理干预措施（名为WithUs）对心力衰竭（HF）患者的初步有效性和可用性。
我们进行了一项采用组内前后测设计和可用性测试的混合方法试点研究。参与者为26名韩国HF患者（20名男性；中位年龄62岁），他们在出院后参加了本研究。在基线和24周干预后，使用问卷和访谈收集数据。结果变量为电子健康素养、疾病知识和自我护理行为。采用Wilcoxon符号秩检验比较干预前后的结果。采用主题分析法分析定性数据。WithUs项目提高了HF患者的电子健康素养（P = 0.005）、疾病知识（P < 0.001）和自我护理行为（P < 0.001）。应用程序总体可用性的中位数得分为4.1分（满分5分）（四分位间距 = 4.0 - 5.0）。确定了四个与定量结果相辅相成的主题。这些主题分别是对日常自我护理行为重要性的认识增加、对自我护理行为的动机增强、适应新应用程序的挑战以及对提高应用程序采用率的建议。
该应用程序在提高HF患者对自我护理行为的依从性、电子健康素养和疾病知识方面是有效的。可用性评估结果表明该应用程序可用，并且有潜力支持HF患者进行自我护理。然而，该应用程序需要进行修改以提高其采用率。
