Picture Archiving and Communication System (PACS) is the support for more accu rate diagnosis in the medical field. Therefore, the present study aimed to determine the factors affecting the continuance of this system . Material and Methods: This is a descriptive - analytic cross - sectional study conducted in 2014. The sample consisted of 200 PACS users (general practitioners, residents , specialists and radiologists ) in Faghihi and Nemazee hospitals of Shiraz which selected by stratified random sampling. Data were collected using a researcher - made questionnaire. To confirm the reliabilit y of the questionnaire, the Cronbach's alpha coefficient (84%) was used and 5 experts from health information management were used to confirm the validity of the questionnaire. The data were analyzed using descriptive and inferential statistics . Results: The study showed that in selected hospitals according to the model, the highest correlation was found between the relationship between expectation confirmation of and satisfaction (r=0.682; R2=0.465) and the least correlation was related to the relations hip between the expectation confirmation and the compatibility (r=0.347; R2=0.120). Also, there was a significant relationship between the level of education of users and the continuance intention to use the PACS system (P=0.008). Radiologists have the hig hest tendency to continue using the PACS system and the least - favored were specialists. Conclusion: The results indicate d that for continued use of information systems by users and increase their satisfaction and the success of systems, consideration of u sers' expectations, requirements and technical requirements of systems to fit the system with the tasks of users before implementing information systems is necessary and inevitable.
