Towards an integrated model of IT acceptance in healthcare

We develop and test an integrated model of IT acceptance that revisits the technology acceptance model (TAM) and compares the role of attitude, use, and compatibility as measures of IT acceptance. A pair of second-order constructs define perceived usefulness in terms of information quality (accuracy, content, format, and timeliness), while perceived ease of use is defined in terms of factors that enable the user to make use of the system (specifically, computing support and user efficacy). Using PLS, we apply the model to the adoption of a clinical management system for hospital workers and find strong support. By assessing levels of user experience we find enabling factors drive a users' initial understanding of the system, while more experienced users focus on usefulness and compatibility. Theoretical and practical contributions are discussed.

► We develop a model of IT acceptance in healthcare based on TAM.
► Compatibility with the way people like to work is a key measure of IT acceptance.
► Training and ease of use are important to novice users.
► Information quality and usefulness are important to experienced users.
