OBJECTIVES: The number of healthcare institutions adopting smartphones continues to increase, implying that their utilization is undoubtedly gaining attention. Understanding the needs of smartphone users will provide a greater opportunity for successful information technology acceptance by expanding the scope of its utilization. This study focuses on how smartphones are accepted and utilized in hospitals and analyzes the factors influencing users' attitude, social influence, and intention of use. METHODS: For the study model, the researcher has mainly adopted the Theory of Reasoned Action and further modified and used the models of Technology Acceptance and Information Systems Success. To test the model empirically, a survey was conducted with 122 professionals on information development teams in Korean tertiary hospitals. RESULTS: The common smartphone usage modes were Internet searching, e-mail, scheduling, and social networking in consecutive order. Phone calls consisted of 51.4% of work-related purposes, while other functions, such as text message, Web browser, and scheduling, were mostly used for personal purposes. Costs, contents quality, innovation, ease of use, and support were shown to have statistically significant effects on user attitude, and social influence, portability, security, content quality, and innovation were significant. User attitude and social influence were both statistically significant with respect to intention of use, with user attitude greater than social influence. CONCLUSIONS: The participating staff were analyzed as having strong personal faith and principles, independent from their external environment. Timely information exchanges among medical staff will facilitate appropriate communication and improved health services to patients in need.

OBJECTIVES: This study evaluated the functional characteristics of hardware and software in Picture Archiving and Communication System (PACS) in dental hospitals and examined the impact of the functional characteristics on user satisfaction, ease of use, and usefulness of PACS. METHODS: A cross-sectional survey was conducted on dentists at 20 dental hospitals. The dentists assessed the functional characteristics of PACS, and also evaluated the outcomes of PACS use such as user satisfaction, ease of use, and usefulness. For each outcome variable, regression analysis was performed to determine the significant functional characteristics influencing each outcome variable. RESULTS: The image quality of device and the diagnosis-supporting function served as the most important factors in user satisfaction. Experience of the PACS system was correlated with ease of use. Dentists specialized in oral maxillofacial surgery evaluated PACS very useful, and intention to participation in education in the future showed significant correlation with usefulness. The more experience of using PACS system and concern about education, the higher usefulness for the system. CONCLUSIONS: This study has significance in that it can be used as reference for constructing high-efficiency system in dental hospitals adopting the PACS system and also in companies producing the system.

OBJECTIVE: An application service provider (ASP) is a business that provides computer-based services to customers over a network. The need for ASPs has developed due to increasing costs of information systems, which have far exceeded the price-range of small to medium sized businesses. The ASP could be considered as a potential strategy in hospital information systems (HIS). This study investigates significant factors influencing the adoption of an ASP in hospitals. METHODS: Two survey instruments were developed for information technology (IT) experts in hospitals and IT companies, respectively, and a total of 101 responses were analyzed using SAS, version 9.1. Respondents' characteristics were presented using descriptive statistics, while factor analyses were performed for ASP characteristics and influencing factors for ASP adoption. Regression analyses enabled the understanding of relationships between factors and attitudes toward ASP adoption. RESULTS: Nine factors were derived: efficiency, availability, responsiveness, security, resistancy, service quality, attitude toward information-oriented work of CEO or IT experts, environment, and user attitude. Except for responsiveness and CEO or IT experts' attitude, the seven factors had significant effects on the adoption of an ASP in hospitals. In particular, security and user attitude showed negative effects on ASP adoption. There were variations in the subsystems of HIS. CONCLUSION: For adopting ASP in hospitals, efficiency, availability, security, resistancy, service quality, environment, and user attitude need to be considered, especially security and user attitude. This study allowed the understanding and comparative analysis of user (hospitals) and supplier (IT companies) perspectives of information systems in terms of ASP adoption in hospitals.

With the institutional and market changes in hospitals, strategic management has become increasingly important. Strategic managerial innovations can have impact on market pioneering and hospital performance, enabling better customer satisfaction, productivity improvement, and quality management. Hospital Information systems also require strategic planning to improve functionality in all aspects. This article reviewed the concept of strategic management and strategic information system (SIS), and summarized a framework for developing SIS for hospitals. The SIS formulation process consists of two interrelated phases: organizational analysis and SIS development. The first phase involves an analysis of the hospital's current position and the development of the hospital's vision and goals. The second phase incorporates three activities: SIS goals assessment, strategic information requirements analysis (SIRA), and SIS implementation planning. In particular, in SIRA, four dimensions of SIS and their interrelationships between dimensions would permit an organization to specify the strategic information needs within a hospital. Hospitals that integrate this framework with other aspects of their own hospital management information systems cope more effectively with the rapid changes and challenges encountered in today's health service industry.

OBJECTIVES: Big data analysis is receiving increasing attention in many industries, including healthcare. Visualization plays an important role not only in intuitively showing the results of data analysis but also in the whole process of collecting, cleaning, analyzing, and sharing data. This paper presents a procedure for the interactive visualization and analysis of healthcare data using Tableau as a business intelligence tool. METHODS: Starting with installation of the Tableau Desktop Personal version 10.3, this paper describes the process of understanding and visualizing healthcare data using an example. The example data of colon cancer patients were obtained from health insurance claims in years 2012 and 2013, provided by the Health Insurance Review and Assessment Service. RESULTS: To explore the visualization of healthcare data using Tableau for beginners, this paper describes the creation of a simple view for the average length of stay of colon cancer patients. Since Tableau provides various visualizations and customizations, the level of analysis can be increased with small multiples, view filtering, mark cards, and Tableau charts. CONCLUSIONS: Tableau is a software that can help users explore and understand their data by creating interactive visualizations. The software has the advantages that it can be used in conjunction with almost any database, and it is easy to use by dragging and dropping to create an interactive visualization expressing the desired format.

OBJECTIVE: With the rapid growth of picture archiving and communication systems (PACS) in the healthcare industry, this article describes the users' satisfaction with PACS by employing functional PACS features and the two concepts of perceived ease-of-use (PEOU) and perceived usefulness (PU), based on the extended technology acceptance model (TAM). METHODS: A cross-sectional survey was conducted with dentists in 25 dental hospitals which were cluster sampled from the national registry of 132 dental hospitals. Of the 204 respondents (response rate 81.6%), the data of 159 PACS users were analyzed using the structural equation modeling method. RESULTS: The fitted model showed significant relations between the technical components and the TAM variables, via the following three significant paths: hardware to PEOU, and software to PEOU and also to PU. Moreover, the critical path of TAM variables was observed: PEOU-->PU-->SAT. Therefore, the model produced three significant routes: hardware-->PEOU-->PU-->SAT, software-->PU-->SAT, and software-->PEOU-->PU-->SAT. CONCLUSION: Contrary to expectations, the direct effect of PEOU on user satisfaction was not significant. The final model provided critical paths from technical components to user satisfaction, by utilizing PEOU and PU as intermediary, latent factors.
