An Analysis of Executive Behavior with Hospital Executive Information Systems in Medical Centers

摘要

Existing Health Information Systems largely only support the daily operations of a medical center, and are unable to generate the information required by executives for decision-making. In this environment, executives must consider not only the best application of information technology, but also how to use this information effectively [1]. Building on past research concerning information retrieval behavior and learning through mental models, this study examines the use of information systems by hospital executives in medical centers. It uses a structural equation model to help find ways hospital executives might use information systems more effectively. The results show that computer self-efficacy directly affects the maintenance of mental models, and that system characteristics directly impact learning styles and information retrieval behavior. Additionally, individual differences between executives and their locus of control impact the usefulness of scan-based information searches. Contextual factors and unstructured work characteristics also impact the usefulness of more focused information searches. Other results include the significant impact of perceived environmental uncertainty on scan searches; information retrieval behavior and focused searches on mental models and perceived efficiency; scan searches on mental model building; learning styles and model building on perceived efficiency; and finally the impact of mental model maintenance on perceived efficiency and effectiveness.
