Various countries have indicated that they have played an effective role in decreasing exposures and its economic costs and attracting optimal resources through establishment of a comprehensive information system for occupational diseases with a appropriate structure. Health improvement is considered as the first aim of the health system which requires a comprehensive, complete and integrated information system on occupational disease.

Main instrument of this research was articles, books, magazines, valid internet sites in English language. Then, the gathered data were classified and analyzed.
Results: All the three selected countries had an electronic information system and database in the field of occupational disease. In Finland, data of occupational diseases as well as their damages are kept in separate databases while US lacks a comprehensive system. There are countless systems in these countries in this field. In France, supervision on laboratories is a priority. In Iran, there is no certain comprehensive system for registering diseases.
