RESUMO
PURPOSE: The purpose of this article was to highlight the importance of data management systems in radiotherapy. METHODS: We performed a database search to review the errors or potential errors in radiotherapy planning and delivery which could be prevented in case of using the DICOM communication system. RESULTS: We registered the following rates of errors: 1) Errors caused by manual rewriting of treatment plan 30%; 2) Errors caused by wrong assignment of the verification system 15%; 3) Errors during the manual rewriting of treatment data to the verification system 15%; 4) Patient identification 5%; 5) Field verification 15% 6) Wedge orientation 10%. CONCLUSION: DICOM communication system may significantly improve the quality assurance in radiotherapy.
