Abstract

BACKGROUND

Research integrating multisensory home-monitoring in respiratory disease is scarce. Therefore, we created a novel multisensory home-monitoring device tailored for long-term respiratory disease management (named the CAir-Desk). We hypothesize that recent technological accomplishments can be integrated into a multisensory participant-driven platform. We also believe that this platform could improve chronic disease management and be accessible to large groups at an acceptable cost.

OBJECTIVE

This study aimed to report on user adherence and acceptance as well as system functionality of the CAir-Desk in a sample of participants with stable chronic obstructive pulmonary disease (COPD) or asthma.

METHODS

We conducted an observational usability study. Participants took part in 4 weeks of home-monitoring with the CAir-Desk. The CAir-Desk recorded data from all participants on symptom burden, physical activity, spirometry, and environmental air quality; data on sputum production, and nocturnal cough were only recorded for participants who experienced symptoms. After the study period, participants reported on their perceptions of the usability of the monitoring device through a purpose-designed questionnaire. We used descriptive statistics and visualizations to display results.

RESULTS

Ten participants, 5 with COPD and 5 with asthma took part in this study. They completed symptom burden questionnaires on a median of 96% (25th percentile 14%, 75th percentile 96%), spirometry recordings on 55% (20%, 94%), wrist-worn physical activity recordings on 100% (97%, 100%), arm-worn physical activity recordings on 45% (13%, 63%), nocturnal cough recordings on 34% (9%, 54%), sputum recordings on 5% (3%, 12%), and environmental air quality recordings on 100% (99%, 100%) of the study days. The participants indicated that the measurements consumed a median of 13 (10, 15) min daily, and that they preferred the wrist-worn physical activity monitor to the arm-worn physical activity monitor.

CONCLUSIONS

The CAir-Desk showed favorable technical performance and was well-accepted by our sample of participants with stable COPD and asthma. The obtained insights were used in a redesign of the CAir-Desk, which is currently applied in a randomized controlled trial including an interventional program.

摘要

背景

整合多感官居家监测用于呼吸系统疾病的研究较少。因此，我们创建了一种专为长期呼吸系统疾病管理量身定制的新型多感官居家监测设备（名为CAir-Desk）。我们假设，近期的技术成果能够整合到一个由参与者驱动的多感官平台中。我们还认为，这个平台可以改善慢性病管理，并且能以可接受的成本供大量人群使用。

目的

本研究旨在报告CAir-Desk在稳定期慢性阻塞性肺疾病（COPD）或哮喘参与者样本中的用户依从性、接受度以及系统功能。

方法

我们进行了一项观察性可用性研究。参与者使用CAir-Desk进行了4周的居家监测。CAir-Desk记录了所有参与者的症状负担、身体活动、肺功能以及环境空气质量数据；只有出现症状的参与者的痰液生成和夜间咳嗽数据被记录。研究期结束后，参与者通过一份专门设计的问卷报告他们对监测设备可用性的看法。我们使用描述性统计和可视化方法来展示结果。

结果

10名参与者，5名患有COPD，5名患有哮喘，参与了本研究。他们完成症状负担问卷的比例中位数为96%（第25百分位数为14%，第75百分位数为96%），肺功能记录比例为55%（20%，94%），腕部佩戴的身体活动记录比例为100%（97%，100%），臂部佩戴的身体活动记录比例为45%（13%，63%），夜间咳嗽记录比例为34%（9%，54%），痰液记录比例为5%（3%，12%），环境空气质量记录比例为100%（99%，100%）。参与者表示，这些测量每天平均耗时13（10，15）分钟，并且比起臂部佩戴的身体活动监测器，他们更喜欢腕部佩戴的身体活动监测器。
