Applying the Technology Acceptance Model to the introduction of healthcare information systems

With the rapid development of information systems and advances in healthcare technology paired with current concerns arise over patients' safety and how to cure them efficiently, the healthcare information systems are attracting the attention of more and more people. The purpose of this study is to propose a conceptual model, appropriate for the intention to use healthcare information systems, by adopting the system, service, and information qualities covered in the Information System Success Model proposed by DeLone and Mclean [1] as the external variables and integrating the three dimensions of perceived usefulness, perceived ease of use, and intention to use — referred to in Venkatesh and Davis' updated Technology Acceptance Model, TAM [2]. This study first analyzes relevant researches on the intention to use such systems as the basis for the questionnaire design, then conducts questionnaire survey among district hospital nurses, head directors, and other related personnel. After the questionnaires are collected, SEM is used to analyze the data. The analysis shows that the proposed factors positively influence users' intention to use a healthcare system. Information, service and system quality influence user's intention through the mediating constructs, perceived usefulness and perceived ease-of-use. Managerial implications are provided accordingly. Suggestions for introducing healthcare information system are then provided as well.

Research Highlights
► This paper explores the factors lead to successful introduction of healthcare information system.
► Information system success model and Technology Acceptance Model are integrated to identify the factors.
► This paper investigates the interrelationships among these factors.
► Information, service and system quality are mediated by perceived usefulness and perceived ease-of-use to influence user's intention to use a healthcare information system.
