Results 30 cervix and endometrial patients were included in the study before and after introduction of the IGRT APR decision making framework. Prior to the introduction of the framework treatment workflows were interrupted and the patient rescanned for 14% of fractions (101/721). This reduced to 7.3% (53/730) after the framework was implemented, representing a reduction of 48%. The primary justifications for rescans prior to implementation were larger rectum (44.6%/45) and smaller bladder volume (35.6%/36). After implementation the main justifications given were smaller bladder volume (52.8%/28) and larger rectum (26.4%/14).

Conclusion The development and implementation of a clinician-directed IGRT APR decision making framework leads to a significant reduction of on-treatment XVI rescans for gynaecological radiotherapy treatment. The framework has augmented the IGRT APRTT skillset, helped standardise actions and reduce uncertainty, improved on-treatment efficiency and reduced the number of imaging exposures delivered to patients. The project has provided a template for developing similar decision making matrices for other complex IGRT sites/techniques e.g. head and neck and SABR.

Law 1 1 The Hong Kong Polytechnic University, Department of Health Technology and Informatics, Hong Kong, Hong Kong (SAR) China Purpose or Objective The radiotherapy (RT) teaching team collaborated with RT and medical physics students to develop education workshops in preparing paediatric cancer patients for RT using semi-immersive virtual reality. This provides a precious opportunity for students to engage with patients and their carers before commencing treatments. Each workshop was led by students under the supervision of academic staff and professionals from both disciplines. Students can sharpen their communication skills and translate what they have learnt in the classroom into actual clinical practice.
