Complex institutions comprising several divisions and departments such as hospitals need access to information.

According to the questionnaires, the results of the collected data were divided into two groups: results of experts and those of system users. In the experts group, after identifying the measures and determinants from the literature, they were presented to experts and with the use of one sample T test, the influencing measures and determinants on the success of hospital information systems have been identified. These measures were provided to users and then the confirmatory factor analysis was performed to assess the validity of questionnaires and structure of the identified determinants from the users’ opinions. Finally, several linear regression analyses were conducted to examine the hypotheses and proposed a model to improve user satisfaction in hospitals.
