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: 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.
