End-user perceptions of the impacts of computer self-efficacy and outcome expectancy on job performance and patient care when using a medical information system

Abstract

The research examines a theoretically sound model linking exogenous variables to dependent variables of interest regarding the use of a computer-based medical information system in a large non-profit hospital. Specifically, the theoretical model links management support, previous system experience, ease of system use and information quality to the medical staff's perceptions of the impact of the computer-based medical information system on the quality of patient care and their job performance, mediated by computer self-efficacy and outcome expectancy. The model was empirically tested using 384 responses to a questionnaire from the medical staff of a large non-profit hospital. The empirical technique employed structural equations with latent variables. The results showed that all the exogenous variables impacted indirectly on the quality of patient care mediated by computer self-efficacy and/or outcome expectancy. Based upon these results, managerial implications, conclusions and directions for future research are provided.
