Rayavaran Dynamic Medical Objects and Documents (DMOD)
Rayavaran is a private company based in Tehran, Iran and a leader in production and implementation of health information management systems.
Rayavaran Co. was established in 1995 by a group of young physicians in Tehran, Iran with the aim of developing a windows based hospital information system (HIS). Their first version of EMR was released in 2000 and is called Dynamic Medical Objects and Documents (DMOD). DMOD has been a breakthrough in the field of EMR in the country since it was the first web/windows-based medical record system in the country which could be adjusted to the different user requirements without the need to modify the source code.
Originally the system consisted of a web server and web calls from desktop applications to dynamically build the html pages by applying the xsl templates to the xml structures containing the patient medical data. The data is stored in an Entry-Attribute-Value (EAV) model in a relational database (SQL Server).
Users and Customers
This system is used in more than 90 hospitals in Iran and has received widespread acceptance and usability. It is capable of storing and presenting a wide range of data types in virtually any format, with the help of custom templates and custom script programming. Users include researchers, lab users, physicians in clinics and inpatient wards, nurses and any other group of practitioners who need to store and retrieve health related data.
Strengths and weaknesses
The main strength of DMOD is its adaptability to almost any kind of medical data and the ability to represent it in the desired format. The main weaknesses of this system are lack of standardized coding for medical concepts and lack of separation of content from layout.
