 Background and Aim: Information technology acceptance model predicts acceptance based on end-users' perceived usefulness and ease of use of technology for a specific purpose. The aim of this study is to understand nursing staff’s adoption of clinical information systems based on information technology acceptance model.

 Materials and Methods: This descriptive- analytic study was conducted on 316 nurses in hospitals affiliated with Semnan University of Medical Sciences (SUMS) and those affiliated with the Social Security Organization (SSO). The data collection tool was a valid and reliable questionnaire . The d ata were analyzed by descriptive statistics, Mann-Whitney and chi-square tests .

 Results: Some 73 % of nurses agreed that the nursing information system provides them with correct information. Besides, 55.7% of nurses had accepted the information system. The results showed that male nurses had admitted clinical information systems more than female ones (P<0.05). Moreover, nurses who were aware of their duties towards the computer program or those who were aware of the goals of computer applications had adopted information technology more (P <0.05).

 Conclusion : Most of the nurses had accepted the clinical information system in their daily work. However, issues such as inadequate number of computers , content design, system c apability problems, and nurses' computer skills and knowledge should be seriously examined . Moreover, several interventions should be planned and developed in technical and individual areas such as enhancement of nurses' IT knowledge , teamwork culture , organizational position , team cooperation, and updating and upgrading the network.

Background and Aim: Despite all inherent advantages of information technology in health sector, its implementation still faces many problems. One of the most important barriers is people’s resistance. This study was carried out to survey the factors affecting the acceptance of information technology by Health Information Management (HIM) staff of Tehran University of Medical Sciences (TUMS) hospitals based on Technology Acceptance Model (TAM) in 2011.

Materials and Methods: It is a descriptive-analytical survey. The population of the study consisted of the HIM staff (363 members) of TUMS hospitals. As the sample, 123 employees were selected. The data gathering tool was a questionnaire the validity and reliability of which were confirmed. The data were collected and analyzed by SPSS software, descriptive statistical methods and Spearman Test.

Results: The results showed that there was a positive direct relationship between perceived ease of use (PEOU) on the one hand and the staff’s attitude and their application of IT on the other hand (R=0.14, P= 0.05 R=0.36, P=0.05). Also, perceived usefulness (PU) had a significant direct effect on the staff’s attitude and their application of IT (R=0.22, P= 0.05 R=0.37, P=0.05).

Conclusion : Perceived ease of use (PEOU) and perceived usefulness (PU) are the factors affecting the acceptance of information technology by the HIM staff of TUMS hospitals. Therefore, it is suggested that the above two principles be considered when designing and implementing the IT systems.

Background and Aim: The function of any technology in a society depends on the culture of that society. Organizational culture leads to a common understanding and agreement on institutional practices. Meanwhile, it is a powerful barrier to change, especially technological change. This study aims to determine the effect of indicators of organizational culture on the unified theory of acceptance and use of technology in hospitals of Rasht, Gilan Province.

Materials and Methods: This is a cross-sectional, descriptive-analytic study . From April to July 2013, 235 questionnaires were completed by health, administrative, financial and educational personnel of Razi, Poursina, and Heshmat Hospitals. For data analysis, such tests as compound reliability test, root mean square of variance, bootstrap test, t-test, and hierarchical regression were applied using Lisrel, PLS and SPSS softwares.

Results: Among the components of organizational culture (performance expectancy, effort expectancy, subjective norm, and facilitating conditions), there was a significant relationship only between "performance expectancy and facilitating conditions" and "behavioral inclination and using computers" (P<0.0001). Gender played no role in the relationship between cultural components and the use of computers (P>0.05).

Conclusion: The results of the study indicate that there is a relationship between organizational culture and application of information technology, and that a unified organizational culture can facilitate and speed up the acceptance and application of information technology.

Background and Aim: Inclusive implementation of Electronic Medical Records (EMR) is more serious because of physicians’ perception. This study was carried out to identify the effects of organizational contextual factors on physicians’ perception regarding EMR’s adoption in 2013 (The merger of Tehran University and Iran). 
Materials and Methods: This was a descriptive, analytical and cross- sectional study in which a sample of 270 physicians working in hospitals affiliated to Tehran University of Medical Sciences was selected. Physicians’ perception toward adoption of EMR has been assessed by Technology Acceptance Model or TAM questionnaire and organizational context variables. Collected data were analyzed by SPSS. The study model was tested by Structural Equation Modeling (SEM) and represented by AMOS. 
Results: The findings showed that perceived usefulness (PU), perceived ease of use (PEOU), management support, physicians’ involvement, physicians’ autonomy, and physician- patient relationship have direct and significant effect on physicians’ attitudes toward EMR adoption. However, training has no significant effect on TAM variables. Moreover, the results showed authorizing proposed conceptual path model explained about 56 percent of the variance of EMR adoption.
Conclusion: The present study revealed that organizational context factors had significant effect on physicians’ attitude toward EMRs’ adoption. The study clearly identified six relevant factors that affected physicians’ perception regarding EMR adoption. These factors should be considered when comprehensive implementation is pursued.
