Introduction:  Electronic Medical Records, which is a valuable system to access the patients information at the hospital, is one of the innovative technologies for the utilization of health information. For its successful implementation, this system should be assessed regarding the factors affecting its adoption and use. The purpose of this study was to review the published articles on the factors influencing the adoption of electronic medical records systematically and according to Information Technology Adoption Theories and to identify and classify the factors affecting the adoption of this system.

Method: The present study is a systematic review survey. Data were collected by searching strategy in valid databases such as Google Scholar, Emerald, Science Direct, SID, MagIran, IranMedex, Pubmed from  2004 to 2014, and then the data were recorded on checklist.

Results: Among the studies that use information technology theories to survey the factors affecting adoption of electronic medical record, TAM model was used more than other models. Factors such as perceived ease of use, perceived usefulness, and social influence of TUATU are the most effective on adoption of electronic medical records.

Conclusion: The results of the study showed, perceived ease of use, perceived usefulness, and social influence are effective factors in adopting EMR. Consequently these factors are recommended to be considered in planning to run systems.
