| Summary: | 碩士 === 國立雲林科技大學 === 工業工程與管理系 === 103 === The emergency department frequently admits patients with external wounds whose injuries require a photographic record for the purpose of national health insurance claims or possible lawsuits. The photo record procedure currently in place has not been able to reduce medical personnel’s workload and ensure effective data organization. The common problem of photo misplacement can easily cause the unnecessary waste of time and resources and mistakes in insurance claims. The Emergency Photography App was developed to address this issue. The app is able to integrate with a hospital’s information systems and patient record systems, to reduce the need of repeated data entries and filing errors with an automatic filing feature. This research worked with the case hospital’s emergency department and data centre to analyze the efficiency of its information system. Despite the advent of mobile technology and applications in recent years, there have not been many studies focusing on their efficacy. Based on the Task-Technology Fit Theory, this research explored the match between task needs and technological functionalities and included exogenous variables to improve the model’s explanatory power and the analytical results.
Data analyses confirmed the model’s overall explanatory power as 92.6% after adjustments and the inclusion of the usability variable. Technology characteristics were shown in the model to have a significant influence on the task-technology fit. Social norm, however, was found to have significant negative effects on system utilization, while individuals and the hospital both affected system performance in a positive way with significance. According to the case hospital, the introduction of this photography App has helped reduce the occurrence of photo misplacement, enabling the hospital to improve on the monthly application points with the national health insurance. In terms of research contributions, the Task-Technology Fit Theory incorporating the usability variable presents a streamlined version of the existing one with enhanced overall explanatory power and the potential of wider applicability. In terms of substantive contributions, the usability of the information system was shown to affect task efficiency. The results give the case hospital important insights into the technology that could lead to technological optimization, functional expansion and wider application. Such information should also help hospital managers duplicate successful technological introduction elsewhere and take advantage of information technologies to enable better work quality and efficiency. The introduction of a new technology should aim at sharing workload, reducing staff turnover and enhancing the standard of hospital care.
