For technology to improve productivity, efficiency, and safety in healthcare setting, an essential prerequisite is utilization by its users. Existing theories about technology acceptance mostly deal with voluntary systems, but many systems used in healthcare settings are mandatory systems, so other outcomes rather than the usage or use itself need to be considered in applying existing models to mandatory health information systems. Thus, the focus is moving on user satisfaction. Also, there is a need to see if the technology acceptance leads to the organisational benefits because investments on the technology should show a return as other investments normally do. This research assumes that major constructs of UTAUT (Unified Theory of Acceptance and Use of Technology) increase user satisfaction and organisational benefits, and aims to integrate existing theoretical frameworks to explain user’s evaluation of mandatory information systems and its impacts in healthcare setting.
