• W2946715442 abstract "Abstract Introduction This paper provides a demonstration of how non‐curated data can be retrospectively cleaned, so that existing repositories of radiotherapy treatment planning data can be used to complete bulk retrospective analyses of dosimetric trends and other plan characteristics. Methods A non curated archive of 1137 radiotherapy treatment plans accumulated over a 12‐month period, from five radiotherapy centres operated by one institution, was used to investigate and demonstrate a process of clinical data cleansing, by: identifying and translating inconsistent structure names; correcting inconsistent lung contouring; excluding plans for treatments other than breast tangents and plans without identifiable PTV , lung and heart structures; and identifying but not excluding plans that deviated from the local planning protocol. PTV , heart and lung dose‐volume metrics were evaluated, in addition to a sample of personnel and linac load indicators. Results Data cleansing reduced the number of treatment plans in the sample by 35.7%. Inconsistent structure names were successfully identified and translated (e.g. 35 different names for lung). Automatically separating whole lung structures into left and right lung structures allowed the effect of contralateral and ipsilateral lung dose to be evaluated, while introducing some small uncertainties, compared to manual contouring. PTV doses were indicative of prescription doses. Breast treatment work was unevenly distributed between oncologists and between metropolitan and regional centres. Conclusion This paper exemplifies the data cleansing and data analysis steps that may be completed using existing treatment planning data, to provide individual radiation oncology departments with access to information on their own patient populations. Clearly, the well‐planned and systematic recording of new, high quality data is the preferred solution, but the retrospective curation of non‐curated data may be a useful interim solution, for radiation oncology departments where the systems for recording of new data have yet to be designed and agreed." @default.
