participation and collection method. The authors examined the data independently and then compared and discussed their independent findings to reach a consensus on the results. Results Quantitative (from the CSEQ) and qualitative data were collected from 73 of 109 RTs, who consented to participate, 66 were female. Data was analysed independently by the authors. RTs responded favourably to PGS, reporting a positive impact on coping with work related stressors, self-awareness, and the majority of participants considered PGS had positive implications for team development and trust. The qualitative data identified the need to address aspects of workplace culture to enable the groups to fully develop and therefore enhance the overall experience of peer supervision for RTs. Conclusion Overall, the data indicates there is a need for the ongoing development of PGS and support structures for RTs in NZ. PGS can improve reflective practice, encourage team dynamics, and provide support for RTs in the clinical setting. This study is ongoing and will be repeated in eight months to detect meaningful changes in staff perceptions of PGS over time. PV-094 Implementation of Quality Audit (QA) in Clinical Radiotherapy Units in HCG in India-A Report M. Pundalika 1 , R. Bilimagga 1 1 Health Care Global Enterprises Ltd, Radiation Oncology, Bangalore, India Purpose or Objective Studies have shown high error rates and geographical misses leading to local recurrence due to faulty process and lack of quality and training. In this study, we evaluate the role of Quality and Uniform Practice of Radiotherapy Technologists (QUPORTT) training program on adherence to quality practices across a chain of radiotherapy facilities in the country. The present study analyses data Chronologically audit was carried out for 11, 10, 8, and 16 centres each year from 2013 onwards. Process implementations with approved radiotherapy forms, prescription cards, treatment charts, demographic stickers, radiotherapy process protocols and standard operating procedures (SOP) including a professional outlook (grooming and dress code) as per NABH audit standards were audited. Entries in registers of different radiotherapy process chains in mould-rooms, treatment rooms, X-ray and Computed Tomography (CT) simulations, were systematically evaluated. Audit on treatment machine variables (daily LINAC checklists, EPID quality assurance, and CT/X-ray daily checks) were recorded. Uniformity of practice in different centres based on initial training programme (Quality and Uniform Practice of Radiotherapy Technologists (QUPORTT-2013) was checked. Advanced training (QUPORTT-2016) along with the discussions on audit programme and internal department audits were carried out in 2016. Results This quality audit resulted in achievement of 82.4% on the professional outlook variables, 88.9% standards of quality assurance in NABH approved patient documents, 94.4% in radiotherapy process standards and SOP and 100% in treatment registers. Recommendations based on these quality indicators included development of mandatory radiotherapy and allied infrastructure and achieving excellence in the expertise of RTT personnel. Conclusion Present-day care for patients receiving radiotherapy, calls for high standards in treatment delivery with complex technology in order to ensure accurate tumour control and between 2013 and 2016. Material and Methods

treatment outcomes. (2) RT Technologists play a crucial role in treatment set-up, reproducibility and execution of treatment delivery. Quality practices are ensured whereby; complex situations are made streamlined and implementable even in tier 2 and tier 3 cities, by the help of QUPORTT. This training also could help upcoming centres at an initial level for ensuring gold standard practices. SP-095 From GTFRCC to GIRO Y.

Abstract text Already thirty years ago afterloading units with a stepping source was available. Such device enabled a high degree of freedom with regard to what dose distributions that was possible to deliver. However, the tools to support the decision on how the dose distribution should be for each individual brachytherapy patient were not available. Not until the introduction of image guided brachytherapy (IGBT) it has been possible to move from point prescription to prescription of dose to a 3 -dimensional target volume in terms of dose volume histogram parameters. The optimal image modality for brachytherapy treatment planning is depending on the treatment site and which type of applicator that is used. Several guidelines on 3D image based treatment planning have been published for various brachytherapy sites the last 10-15 years and these guidelines usually recommend and discuss the optimal image modality. To be able to optimise the dose
