Nowadays, the main concern for any service provider organization is to improve their services with reducing the time of service accompanying with increase in their efficiency and effectiveness. In healthcare systems, specially, these concerns are much more important where the information is the core material of providng services to patients. Electronic health record (EHR) systems are designed to address these concerns and using them is becoming more and more important for many countries. EHR systems provide many capabilities to hospitals with collecting, sharing and manipulating information in the digitals format. Moreover, actual EHR systems enable hospitals to share their patient information with any other hospital no matter of the first location of storing data. Incorporating a system with the main goal of making integrity between different organizations is not an easy task and many challenges and problems should be considered to make the system efficient for the organizations. Although many good attempts have been done in some developing countries such as Denmark and USA this issue is still a big challenge for many developing countries. In this research study, it is tried to review the situation of EHR systems in a developing country to extract the challenges and barriers for adopting it. At first, the researcher has a deep literature review on past works on EHR from different aspects. After extracting needed information, a case study will be run to better understanding of the real situation and make a comparison between the literature and real environment. The researcher selected Iran as a developing country to review its healthcare system and the degree of using computerized system in the organizations.
