Technology validation for e-trial systems

[摘要] This research study presents a Hypothesised Model, developed on the basis of the Unified Theory of Acceptance and Use of Technology (UTAUT). Its aim is to evaluate innovative Health Information Technology (HIT) at the early stages of projects. It is contended that this practice would support system developers at the design and implementation phases, and reduce the risk of underutilisation or rejection. The performance of the model was tested in three studies within the Clinical Trial Management Systems framework. The Hypothesised Model approaches Behavioural Intention from a socio-technical point of view, taking into consideration the complexity and need of HIT to achieve joint optimisation. Moreover, it simplifies and extends UTAUT so that it may fit soundly within the healthcare context. Hence, it excludes the moderators and adds three core constructs, including: System-Specific Features, Technology Anxiety, and Adaptation Timeline. However, the model is easily adjustable to fit specific situations, especially given that this research study posits the non-existence of a single model that suits all situations. This approach appears to have improved the final outcome and outperformed the use of generic models within the healthcare context. The total explained variance reported from the three studies is: (76%), (86%), and (87%) respectively.
