User Satisfaction Regarding Hospital Information Systems: Structural Equation Modeling

User satisfaction is considered as the most important criterion of information system effectiveness. The aim of this study was to determine the factors affecting user satisfaction regarding hospital information systems.
This was a descriptive-analytical study. The study population consisted of users of information systems of the teaching hospitals affiliated to Tabriz University of Medical Sciences, Iran. A questionnaire was designed based on the findings from literature review. After assessing the validity of the questionnaire with the help of medical informatics and health information management experts and its final confirmation, questionnaires were distributed among 384 users that had been selected through stratified random sampling. Structural equation modeling was used for data analysis.
Overall, 8 domains of factors related to user satisfaction regarding hospital information system (HIS) were confirmed to be statistically significant by structural equation modeling. They included information quality (estimate = 1), system quality (CR = 3.891), service quality (CR = 5.039), organizational structure and managing style (CR = 4.648), system usefulness (CR = 3.683), system use (CR = 4.963), user characteristics (CR = 5.043), and computer anxiety (CR = 4.963). The significance level of all domains was P The integrated model obtained from this study can be used as an effective tool in design, development, and management of user-driven HISs. This can contribute to enhancing user satisfaction which can prevent wasting of financial and human resources.
