Abstract
Introduction: Users’ behavioral intention to use the Picture Archiving and Communication System (PACS) is important in the systems’ success and is an indicator of the users’ satisfaction with commitment and dependence on information systems. The present study aimed to evaluate the users’ continuous intention to use PACS based on the expectation confirmation model in educational hospitals of Shiraz University of Medical Sciences.Method: This cross-sectional study was conducted in Nemazee and Shahid Faghihi hospitals, Shiraz, Iran in 2014. The subjects were50 general practitioners, residents and specialists selected through stratified random sampling. The study data were collected using a researcher-made questionnaire. The content validity of the questionnaire items was confirmed by five experts in health information management. To evaluate the accuracy of relationships among the measurement models, reliability criteria, including Cronbach’s alpha and composite reliability, convergent and divergent validity were used which showed acceptable reliability and validity. The data were entered into Smart PLS software, version 3.1.9 and analyzed through Structural Equation Modeling (SEM) by using Partial Least Squares (PLS) approach.Results: The results showed appropriate fitness of reliability indices (Cronbach’s alpha >0.7, composite reliability >0.7, loading >0.7), validity indices (AVE >0.5), structural  model (redundancy  =0.395, Q2CI=0.364, f2H5=0.524, R2CI=0.687), and the total model (GoF=0.518). Moreover, all the research hypotheses, except H1 (the relationship between expectation confirmation and perceived usefulness) with T-value of <1.96, showed a significant relationship (T-value >1.96).Conclusion: Expectation confirmation, perceived usefulness, and satisfaction were effective in continuous intention to use PACS. Thus, these factors should be considered by designers, developers, and managers while designing and implementing information systems to guarantee their success and improve the quality of health services.Keywords: Information Systems, Expectation confirmation model, PACS, Satisfactio
