To evaluate whether a new home intervention system (HIS, OPTILOGG(®)) consisting of a specialised software, a tablet computer (tablet) wirelessly connected to a weight scale may improve self-care behaviour, health-related quality of life (HRQoL), knowledge about heart failure (HF) and reduce hospital days due to HF.
82 patients (32% females) with mean age: 75 ± 8 years hospitalised with HF were randomised at discharge to an intervention group (IG) equipped with the HIS or to a control group (CG) receiving standard HF information only. The tablet contained information about HF and lifestyle advice according to current guidelines. It also showed present dose of diuretic, changes in patient-measured weight and HRQoL over time.
After 3 months the IG displayed a dramatic improvement in self-care with p < 0.05 (median IG: 17 [IQR: 13, 22] and CG: 21 [IQR: 17, 25]). The disease-specific HRQoL was measured by Kansas City Cardiomyopathy Questionnaire. The IG had significantly higher score (median IG: 65.1 [IQR: 38.5, 83.3] vs. CG: 52.1 [IQR: 41.1, 64.1] p < 0.05) and an improved physical limitation (median IG: 54.2 [IQR: 37.7, 83.3] vs. CG: 45.8 [IQR: 25.0, 54.2] p < 0.05) There was no difference in knowledge. IG showed fewer HF-related days in the hospital, with 1.3 HF-related hospital days/patient versus 3.5 in CG (risk ratio: 0.38; 95% confidence interval: 0.31-0.46; p < 0.05).
HF patients with a HIS tablet computer and scale improved in self-care and HRQoL. Days in hospital due to HF were reduced. A medical device that is easy to use can be a valuable tool for improving self-care and outcome in patients with HF.
评估一种由专用软件、无线连接体重秤的平板电脑组成的新型家庭干预系统（HIS，OPTIMALOGG(®)）是否可以改善自我护理行为、健康相关生活质量（HRQoL）、关于心力衰竭（HF）的知识，并减少因HF导致的住院天数。
82例平均年龄为75±8岁的HF住院患者（32%为女性）在出院时被随机分为配备HIS的干预组（IG）或仅接受标准HF信息的对照组（CG）。平板电脑包含根据当前指南的HF信息和生活方式建议。它还显示了当前利尿剂剂量、患者测量体重的变化以及随时间的HRQoL。
3个月后，IG在自我护理方面有显著改善，p<0.05（IG中位数：17[四分位间距：13，22]，CG：21[四分位间距：17，25]）。特定疾病的HRQoL通过堪萨斯城心肌病问卷进行测量。IG的得分显著更高（IG中位数：65.1[四分位间距：38.5，83.3]，CG：52.1[四分位间距：41.1，64.1]，p<0.05），身体限制得到改善（IG中位数：54.2[四分位间距：37.7，83.3]，CG：45.8[四分位间距：25.0，54.2]，p<0.05）。知识方面没有差异。IG的HF相关住院天数较少，每位患者HF相关住院天数为1.3天，而CG为3.5天（风险比：0.38；95%置信区间：0.31 - 0.46；p<0.05）。
配备HIS平板电脑和体重秤的HF患者在自我护理和HRQoL方面有所改善。因HF导致的住院天数减少。一种易于使用的医疗设备可以成为改善HF患者自我护理和预后的有价值工具。
