Conclusion The analysis of retrospective CBCTs allowed to evaluate which immobilization procedure is best suited for TMI patient setup and to optimize the procedure. Thanks to this study, all future patients will be positioned with arms leaning on the frame, and feet immobilized with a personal cushion. Thus, the role and experience of the RTT in TMI patient setup is fundamental.

1 Imperial College Healthcare NHS Trust, Radiotherapy, London, United Kingdom; 2 Sheffield Hallam University, Health Research Institute, Sheffield, United Kingdom; 3 The Society and College of Radiographers, Professional Practice and Education, London, United Kingdom Purpose or Objective Current radiotherapy practice suggests that RISR presents the same in all skin tones, however research shows there may be significant differences. This survey aimed to understand what tools and evidence-based practice is being used across the workforce and if confidence levels vary between assessing, managing and teaching RISR; allowing understanding of any national training needs. Materials and Methods Post publication of the Radiation Dermatitis Guidelines (Society and College of Radiographers, 2020), a survey was developed (AlchemerTM survey tool) to assess confidence in assessing and managing RISR. The survey included questions on grading tools used to assess RISR literature and confidence in assessing, managing and teaching RISR across skin tones. The survey was piloted (n=35) before national dissemination. Each radiotherapy department in the UK was contacted between August-November 2021. Descriptive statistics were used to understand respondents differing confidence in assessing skin reactions between white and darker skin tones; Fisher’s exact test was used to determine statistical significance. The majority of respondents (74.2% n=303) use information developed locally, with less than a third of respondents using SCoR evidence based patient leaflets. Higher confidence (score 4 and 5) in assessing RISR was reported in lighter skin vs. darker skin (74% n=302 vs. 41.9% n=171, p<0.0001). Confidence in managing skin reactions was higher in lighter compared to darker skin tones (66.9% n=273vs 49% n=200, p<0.0001). Respondents were more confident in teaching assessments in lighter compared to darker skin tones (60.5% n=247vs 42.6% n=174, p<0.0001). Conclusion Lighter skin tones are more confidently assessed for RISR than darker skin tones in the sample of the radiotherapy workforce that responded to the survey. Higher levels of confidence were seen within the workforce who had been qualified longer. Confidence does not necessarily suggest competence, and the findings should be explored further. Future work should focus on developing strong RISR education and training and review of the current assessment tools. 1 Utrecht UMC, Radiation Oncology, Utrecht, The Netherlands; 2 Fontys Hogeschool, MBRT, Eindhoven, The Netherlands; 3 Amsterdam UMC, Radiation Oncology, Amsterdam, The Netherlands; 4 Leiden UMC, Radiation Oncology, Leiden, The Netherlands; 5 Elekta, Sales, Best, The Netherlands; 6 Philips , Healthcare, Best, The Netherlands; 7 Catharina Hospital , Radiation Oncology, Eindhoven, The Netherlands Purpose or Objective Over the last years there has been a rapid growth in the number of state-of-the-art MRI scanners and MR-Linacs in radiotherapy clinics. These technological advances have made radiation therapy more precise and have improved accuracy in delineation and online image guidance. The role and responsibilities of the RTT are evolving and new educational programs are necessary using these new techniques. A survey by all RT institutes in the Netherlands has indicated there is a need for extra education for RTTs working in MR guided Radiotherapy (MRgRT). This abstract reports on the development and evaluation of a new course in MRgRT for RTTs and other specialists working with MR in RT. Materials and Methods This MRgRT course is developed in collaboration between the Fontys University, Amsterdam UMC, Catharina Hospital Eindhoven, Utrecht UMC and industry. RTTs, application specialists, product experts, medical physicist experts and radiation oncologists have developed modules, hands-on exercises and presentations within this course. A non-vendor Results A total of 406 complete responses were received from therapeutic radiographers across the UK. The most commonly used RISR assessment tool was Radiation Therapy Oncology Group (RTOG) (58% n=237).
