| Summary: | 碩士 === 國立臺灣科技大學 === 設計系 === 105 === The intractable process of intravenous infusion therapy (IV infusion) has been a common problem that increasing the workload for nursing staff. Along with the development of eHealth promoted by Internet of things (IOTs) technology, remote monitoring IV infusion process is considered to be a novel solution to this long-standing problem. Also, at the time of building an intravenous infusion monitoring, it’s necessary to ensure not only the stable operation of the system but also the effective information transmission of the user interface (UI). After all, The user interface effectively deliver Infusion process will directly influence nurses' recognition and decision-making, which has a significant impact on the performance of the IV infusion operations.
In order to understand how to provide a monitoring UI that meets the needs of nursing staff, this study adopted a prototype as a test sample for related discussions about its visual presentation, usability, and practical benefits to intravenous therapy. Three phases are designed in the experiment methods and procedures. The pilot study phase is to establish the prototype. Firstly, collecting the UI requirement from nursing staff with semi-structured interviews. Secondly, Case study is applied to understand the UI features for sorting and management. Finally, integrating the demands and the UI features to build the prototype version 1.0. In the first usability evaluation, task testing and semi-structured interviews are adopted to understand the experiences and opinions from nursing staff who operates prototype V1.0. The usability problems and recommendations were defined with induction. Then the results were applied in the improvement for the prototype. (Version 1.0 was upgraded to version 2.0.) In the final phase, the second usability evaluation, task testing and semi-structured interviews were also conducted as the first usability evaluation, and then the improvement results were inspected with the feedback from the nursing staff.
Based on the results from each phase, the conclusions are drawn as follows: (1) The findings in user-centered design process: The importance of cycling evaluation and the nursing staff is liable to compromise with the usability problems ; (2) Design elements of monitoring UI: A monitoring UI is suggested to include simple interaction mode, clear visual presentation, straight-column monitoring pages, intuitive volume information, obvious alert messages, unambiguous patient Information, obvious infusion record, permanent process information, distinct classification of infusion type ; (3) Practical benefits of an intravenous infusion monitoring system: The system is very suitable for general ward, and its functionality can be enhanced through integrating with other clinical information systems.
