New technologies have allowed remote real-time electronic recording of symptoms and spirometry. The feasibility of utilising this technology in COPD patients has not been investigated. This is a feasibility study. The primary objective is to determine whether the use of an electronic diary with a portable spirometer can be performed by COPD patients with a moderate to severe disease. Secondary objectives are to investigate the value of this method in early detection of acute exacerbations of COPD (AECOPD). In this 6-month study, 18 patients recorded daily their symptom score and spirometry. Data was sent on real time. AECOPD which was defined according to pre-set criteria were noted. Spirometry values and scores for health-related quality of life were compared between the start and the end of the study. Hospitalisation rate due to AECOPD was compared with a parallel period in the previous year. On average, patients were able to record 77% of their total study days. The system detected 73% of AECOPD. In further 27% of AECOPD patients sought treatment although the change in symptoms did not meet AECOPD definition. The number of COPD-related hospitalisations significantly reduced compared to the previous year. There was a significant increase in FEV(1) and FVC from the start to the end of the study. The remote monitoring device used in this study can be used in COPD patients. AECOPD was detected early in the majority of cases. Hospitalisation rate due to AECOPD was reduced and FEV(1) and FVC values increased during the study.
新技术已经可以实现远程实时电子记录症状和肺量测定。但尚未对利用该技术在 COPD 患者中的可行性进行调查。这是一项可行性研究。主要目的是确定使用带有便携式肺量计的电子日记能否由中重度 COPD 患者执行。次要目标是研究该方法在早期发现 COPD 急性加重（AECOPD）中的价值。在这项为期 6 个月的研究中，18 名患者每天记录他们的症状评分和肺量测定值。数据实时发送。根据预设标准记录 AECOPD。比较研究开始和结束时的肺量计值和健康相关生活质量评分。比较因 AECOPD 而住院的比率与前一年同期的比率。平均而言，患者能够记录其总研究天数的 77%。该系统检测到了 73%的 AECOPD。在另外 27%的 AECOPD 患者中尽管症状的变化不符合 AECOPD 定义，但仍寻求了治疗。与前一年相比，因 COPD 相关的住院率显著降低。从研究开始到结束，FEV（1）和 FVC 显著增加。本研究中使用的远程监测设备可用于 COPD 患者。在大多数情况下可以早期检测到 AECOPD。因 AECOPD 而住院的比率降低，并且在研究过程中 FEV（1）和 FVC 值增加。
