Wearable devices have been used extensively both inside and outside of the hospital setting. During the COVID-19 pandemic, in some contexts, there was an increased need to remotely monitor pulse and saturated oxygen for patients due to the lack of staff and bedside monitors.
A prototype of a remote monitoring system using wearable pulse oximeter devices was implemented at the Hospital for Tropical Diseases in Ho Chi Minh City, Vietnam, from August to December 2021. The aim of this work was to support the ongoing implementation of the remote monitoring system.
We used an action learning approach with rapid pragmatic methods, including informal discussions and observations as well as a feedback survey form designed based on the technology acceptance model to assess the use and acceptability of the system. Based on these results, we facilitated a meeting using user-centered design principles to explore user needs and ideas about its development in more detail.
In total, 21 users filled in the feedback form. The mean technology acceptance model scores ranged from 3.5 (for perceived ease of use) to 4.4 (for attitude) with behavioral intention (3.8) and perceived usefulness (4.2) scoring in between. Those working as nurses scored higher on perceived usefulness, attitude, and behavioral intention than did physicians. Based on informal discussions, we realized there was a mismatch between how we (ie, the research team) and the ward teams perceived the use and wider purpose of the technology.
Designing and implementing the devices to be more nurse-centric from their introduction could have helped to increase their efficiency and use during the complex pandemic period.
可穿戴设备在医院内外都得到了广泛应用。在 COVID-19 大流行期间，由于人员短缺和床边监护仪不足，在某些情况下，需要远程监测患者的脉搏和血氧饱和度。
2021 年 8 月至 12 月，在越南胡志明市热带病医院实施了一个使用可穿戴脉搏血氧仪设备的远程监测系统原型，旨在为正在进行的远程监测系统实施提供支持。
我们采用行动学习方法，结合快速实用方法，包括非正式讨论和观察，以及根据技术接受模型设计的反馈调查表格，评估系统的使用情况和可接受性。根据这些结果，我们使用以用户为中心的设计原则召开了一次会议，更详细地探讨了用户的需求和对系统开发的想法。
共有 21 名用户填写了反馈表。技术接受模型的平均得分范围从 3.5（感知易用性）到 4.4（态度），行为意向（3.8）和感知有用性（4.2）的得分在中间。护士的感知有用性、态度和行为意向得分高于医生。根据非正式讨论，我们意识到我们（即研究团队）和病房团队对技术的使用和更广泛的用途存在理解上的差异。
从引入开始，将设备设计得更侧重于护士，可能有助于在复杂的大流行期间提高其效率和使用。
