Background: In recent years lots have been done for hospital automation but this non harmonized ac­tions leads to different software usage and entrance of different data into the system when partly is not useful . In this way, usage of soft wares in medical records specialty in the high loaded reception and recording will decrease defect in registration and storage of medical data. Using computerized system which cover applied soft wares could decrease many problems in medical data records. Any research in medical record area needs to be fed with data there fore it should be to use and evaluation of comput­erized systems. 

Method: This cross sectional study was conducted in reception and recording department teaching hospitals of Tehran University of Medical Sciences (TUMS), Iran, using check list and direct collection of the data in the hospital. We used descriptive statistics tools to analysis the data.

Results: Specialized hospital and general hospital use computerized system for medical record with percents of 49.06% and 40.73% respectively .search of the input data and output data were considered as 66.7%.

Conclusion: The usage of automation in reception and recording departments of TUMS hospitals was low and even the operating system was not capable to register the patients data. Even though a few humble of systems in medical records awards were set which would be the source of some problems is saving and processing the data.
