An incentive spirometer (IS) is a medical device used to help patients improve the functioning of their lungs. It is provided to patients who have had any surgery that might jeopardize respiratory function. An incentive spirometer plays a key role in the prevention of postoperative complications, and the appropriate use of an IS is especially well known for the prevention of respiratory complications. However, IS utilization depends on the patient's engagement, and information and communication technology (ICT) can help in this area.
This study aimed to determine the effect of mobile ICT on the usage of an IS (Go-breath) app by postoperative patients after general anesthesia.
For this study, we recruited patients from April to May 2018, who used the Go-breath app at a single tertiary hospital in South Korea. The patients were randomly classified into either a test or control group. The main function of the Go-breath app was to allow for self-reporting and frequency monitoring of IS use, deep breathing, and active coughing in real time. The Go-breath app was identical for both the test and control groups, except for the presence of the alarm function. The test group heard an alarm every 60 min from 9 am to 9 pm for 2 days. For the test group alone, a dashboard was established in the nurse's station through which a nurse could rapidly assess the performance of multiple patients. To evaluate the number of performances per group, we constructed an incentive spirometer index (ISI).
A total of 44 patients were recruited, and 42 of them completed the study protocol. ISI in the test group was 20.2 points higher than that in the control group (113.5 points in the test group and 93.2 points in the control group, P=.22). The system usability scale generally showed almost the same score in the 2 groups (79.3 points in the test group and 79.4 points in the control group, P=.94). We observed that the performance rates of IS count, active coughing, and deep breathing were also higher in the test group but with no statistically significant difference between the groups. For the usefulness "yes or no" question, over 90% (38/42) of patients answered "yes" and wanted more functional options and information.
The use of the Go-breath app resulted in considerable differences between the test group and control group but with no statistically significant differences.

激励式肺活量计（IS）是一种用于帮助患者改善肺部功能的医疗设备。它提供给那些接受过可能危及呼吸功能的手术的患者。激励式肺活量计在预防术后并发症方面起着关键作用，其正确使用尤其以预防呼吸并发症而闻名。然而，IS 的使用取决于患者的参与度，而信息和通信技术（ICT）可以在这方面提供帮助。
本研究旨在确定移动 ICT 对全麻术后患者使用 Go-breath 应用程序（IS）的影响。
在这项研究中，我们招募了 2018 年 4 月至 5 月在韩国一家三级医院使用 Go-breath 应用程序的患者。这些患者被随机分为测试组或对照组。Go-breath 应用程序的主要功能是允许患者实时自我报告和监测 IS 使用、深呼吸和主动咳嗽的频率。Go-breath 应用程序对测试组和对照组都是相同的，只是没有报警功能。测试组从上午 9 点到晚上 9 点每 60 分钟响一次警报，持续 2 天。仅为测试组建立了一个仪表盘，护士站可以通过该仪表盘快速评估多个患者的表现。为了评估每组的执行次数，我们构建了激励式肺活量计指数（ISI）。
共招募了 44 名患者，其中 42 名完成了研究方案。测试组的 ISI 比对照组高 20.2 分（测试组 113.5 分，对照组 93.2 分，P=.22）。系统可用性量表在两组中的得分基本相同（测试组 79.3 分，对照组 79.4 分，P=.94）。我们观察到 IS 计数、主动咳嗽和深呼吸的执行率在测试组中也更高，但组间无统计学差异。对于“是或否”的有用性问题，超过 90%（38/42）的患者回答“是”，并希望有更多的功能选项和信息。
Go-breath 应用程序的使用在测试组和对照组之间产生了显著差异，但无统计学意义。
