The use of eHealth as a monitoring system in people with heart failure (HF) has been shown to be effective in promoting self-care and reducing re-admissions and mortality. The present study develops and evaluates the accessibility and usability of the web app iCardioMonitor HF monitoring system. This study consisted of two stages. The first stage (co-design) comprised two phases: (1) analysis of the scientific literature and expert opinions and (2) co-design of the iCardioMonitor (web app plus a knowledge-base algorithm) and definition of alert criteria. The second stage (cross-sectional descriptive study) analyzed system accessibility (% of people using the iCardioMonitor and % of parameters recorded) and usability, employing the Spanish version of the System Usability Scale for the Assessment of Electronic Tools. The iCardioMonitor was configured by a web app and an algorithm with the capacity to detect decompensated HF automatically. A total of 45 patients with an average age of 55.8 years (standard deviation [SD] = 10.582) and an average time since diagnosis of 7.1 years (SD = 7.471) participated in the second stage. The percentage of iCardioMonitor use was 83.2%. The average usability score was 77.2 points (SD = 21.828), higher in women than men (89.2; SD = 1.443-76.0; SD = 1.443) ( = 0.004). The usability score was higher the shorter the time since diagnosis (r = 0.402; = 0.025) and the higher the number of responses (r = 0.377; = 0.031). The results obtained show that iCardioMonitor is a tool accepted by patients and has obtained a remarkable score on the usability scale. iCardioMonitor was configured by a web app and an algorithm with the capacity to detect decompensated HF automatically.
已证明，将电子健康（eHealth）用作心力衰竭（HF）患者的监测系统，在促进自我护理、减少再入院率和死亡率方面是有效的。本研究开发并评估了网络应用程序iCardioMonitor HF监测系统的可及性和可用性。本研究包括两个阶段。第一阶段（协同设计）包括两个阶段：（1）科学文献和专家意见分析，以及（2）iCardioMonitor（网络应用程序加知识库算法）的协同设计和警报标准的定义。第二阶段（横断面描述性研究）使用西班牙文版的电子工具评估系统可用性量表，分析系统的可及性（使用iCardioMonitor的人群百分比和记录的参数百分比）和可用性。iCardioMonitor由一个网络应用程序和一个能够自动检测失代偿性HF的算法配置而成。共有45名患者参与了第二阶段，平均年龄为55.8岁（标准差[SD]=10.582），自诊断以来的平均时间为7.1年（SD=7.471）。iCardioMonitor的使用率为83.2%。平均可用性得分为77.2分（SD=21.828），女性得分高于男性（89.2；SD=1.443 - 76.0；SD=1.443）（P=0.004）。自诊断以来时间越短，可用性得分越高（r=0.402；P=0.025），回复数量越多，可用性得分越高（r=0.377；P=0.031）。获得的结果表明，iCardioMonitor是患者接受的一种工具，并且在可用性量表上获得了显著分数。iCardioMonitor由一个网络应用程序和一个能够自动检测失代偿性HF的算法配置而成。
