The implementation of information systems throughout the healthcare industry has increased dramatically over the past decade since it is now generally believed that IS/IT will be able to bring about immense benefit to medical personnel in delivering better services. However, the enthusiasm of having new information systems implemented usually deteriorates dramatically once the system is acquired. This causes a major issue in the assimilation of the newly implemented technology which could provide a negative impact on the successful ongoing use of the information system. This paper describes a research in progress that explores key technology innovation assimilation issues in a healthcare setting with the aim of developing a technology innovation assimilation model for hospitals to successfully implement and sustain the use of the healthcare information system.
