Purpose: Many radiotherapy (RT) databases are generated in the clinics in treatment planning systems (TPS) and oncology information systems (OIS). So far, much of the work to retrieve and coordinate RT-data has been done manually. Swedish quality registries for cancer are presently diagnose specific with very sparse and varying information on RT. Access to structured RT-databases and quality registries containing relevant quality parameters is necessary for efficient research, clinical evaluation and reporting.
Methods: An IT solution designed to facilitate a national quality registry for radiotherapy is implemented. The solution consists of a local storage of DICOM RT data in a structured database, Medical Information Quality Archive (MIQA), and an application for recalculation of the data from the 4D representation to dose-volume parameters for each fraction. These parameters are then sent to the platform that hosts the Swedish quality registries for cancer, Information Network for Cancer Care (INCA). MIQA is a multipurpose system that provides data to the RT-registry and can also be used as a research database. MIQA includes basic functionality to monitor the status of the treatment for patients in order to send only data sets for complete treatment courses.
Results: A national Swedish naming convention has been published. The convention is adapted to international standards. The technical infrastructure has been verified, with transfer of information from clinical systems to the MIQA data base through DICOM and direct reading in the information systems, to the calculation of volumes and dose volume descriptors and in cooperation in INCA. The installations of MIQA is installed at a majority of RT clinics in Sweden and the coverage is estimated to be complete by end of 2017.
Conclusion: A national IT solution for a structured registration of RT-data is a powerful tool for research, clinical evaluation and reporting.
