Introduction: Picture Archiving and communication system (PACS) has caused a revolution in radiology performance and has increased efficiency in medicine and radiology. Identifying the important factors influencing the success and failure of PACS is necessary to ensure its successful implementation. This study aimed to determine the success factors of PACS using structural equation modeling approach in educational hospitals of Shiraz University of Medical Sciences, Shiraz, Iran.Methods: This cross-sectional, descriptive-correlational study was conducted in 2014. The study population consisted of PACS users (general practitioners, specialists, residents, and radiology experts) in Faghihi and Nemazi Hospitals of Shiraz. The subjects consisted of 250 PACS users, who were selected using stratified random sampling. A questionnaire was used to collect data; its validity was confirmed using confirmatory factor analysis and its reliability was measured using Cronbach's alpha (α = 0.84). Data were analyzed using descriptive statistical methods in SPSS and structural equations modeling technique in LISREL software.Results: Findings showed that the proposed conceptual model for success of PACS in Shiraz University of Medical Sciences has an appropriate fitness in terms of analysis of the constitutive factors. Hypothesis analysis using structural equation modeling showed that 11 hypotheses out of 16 were confirmed and 5 hypotheses w refuted. Factors of individual performance, organizational performance, and perceived usefulness of the system had the greatest impact on the dependence on PACS, respectively.Conclusion: Designing and evaluating health information systems based on standard and well-known models is necessary in order to have quality information, quality systems, and satisfied users. Findings of this study can be a good reference for health care institutions, companies which provide information system services, and information system developers in order to evaluate and promote the quality, usability, and effectiveness of these systems.

Introduction: To successfully implement new information systems in health care, especially electronic medical records, it is important to understand the factors that influence the adoption of these systems in the opinions of users, particularly managers. Therefore, the purpose of this study was to determine the factors affecting the adoption of electronic medical records using the technology acceptance model (TAM). Methods: This descriptive-analytical survey was conducted in 2015. The study population consisted of 235 top and middle managers of teaching hospitals in Shiraz, Iran. The subjects were selected through census method without the use of sampling. Data were collected using the standard TAM questionnaire and analyzed in SPSS and LISREL software using regression analysis, independent t-test, and ANOVA. Results: The findings of this study showed a positive direct relationship between perceived ease of use and attitude of the users (r = 0.46) (P < 0.05). There was also a positive, direct relationship between perceived usefulness and attitude toward use (r = 0.42) (P < 0.05). In addition, there was a positive, direct relationship between attitude toward use and actual use (r = 0.36) (P < 0.03). Conclusion: In evaluations and plans, through the consideration of factors of perceived usefulness and perceived ease of use, which affect the attitude toward use, the adoption of the electronic medical records system among top and middle managers in hospitals can be improved.

Introduction: One of the main characteristics of a hospital information system (HIS) is confidentiality.Studies have shown that the security requirements on electronic health records are not fully met in Iran.This study was conducted to determine the percentage of HIPAA (health insurance portability andaccountability act) security safeguard application in university hospitals of Shiraz University of MedicalSciences in 2010.Methods: This was a cross-sectional descriptive study. The study population included university hospitalsof Shiraz University of Medical Sciences equipped with HIS. Data were collected by a checklist throughinterview with the IT authorities of the hospitals. The checklist was in accordance with HIPAA securitystandard rules. Tool validity was checked by the content validity method. Data were analyzed usingdescriptive statistics.Results: The risk management and data backup plan, two out of seven required administrative securitysafeguards (i.e. risk analysis, risk management, sanction policy, information system activity review, databackup plan, disaster recovery plan, and emergency mode operation plan), were fully applied in all thehospitals. Both of two required physical security safeguards, disposal and media reuse, were applied in themajority of the hospitals. Of the two required technical security safeguards, unique user identifications,and emergency access procedure were applied only in one of the hospitals.Conclusion: Operational planning must be implemented in order to increase the application of requiredadministrative security safeguards. Full application of the required physical security safeguards, which areclose to reach, and the required technical security safeguards could be the main steps in promotingsecurity of the HIS.
