Understanding continuance intentions of physicians with electronic medical records (EMR): An expectancy-confirmation perspective

摘要

This paper examines physicians' continuance intentions with electronic medical records (EMR) in the post-adoption phase. Expectation-confirmation theory (ECT) is used with the incorporation of perceived risk as the theoretical foundation. Based on the extended ECT model, eight hypotheses were formulated to aid in the understanding of physicians' continuance intentions. A field survey of 135 Canadian physicians that utilize EMR systems was conducted to test these hypotheses. The study found that physicians are willing to continue using EMR systems. In addition, the empirical results suggest that perceived usefulness and perceived risk impact satisfaction, which in turn influences physicians' continuance intentions. In addition, perceived risk also has a direct influence on physicians' continuance intentions. These results contribute to the IT adoption and use literature, particularly in the post-adoption context.
