available. We found that clinical trials involving more than one institution were associated with a better publication rate. Trials funding in radiotherapy should take this result into account to better optimize human and economic resources. Non-publication means a poor use of financial resources, a loss of knowledge through hidden data, and poses an ethical issue with our patient community.

The IAEA conducted a survey using two sets of validated radiation oncology quality indicators (ROI). The purpose was to assess the quality of radiotherapy services provided in order to identify areas of weakness for further improvement and support. Material and Methods 11 countries were assessed: Armenia, Azerbaijan, Belarus, Georgia, Kazakhstan, Kyrgyzstan, Moldova, Russian Federation, Tajikistan, Ukraine, and Uzbekistan. A country coordinator was identified for each country and acted as the liaison between the country and the IAEA providing the required data. The methodology was a cross-sectional one-time study survey using a 58-question tool in Russian which was sent

to all participating centres. The questionnaire was based on two previously validated sets of ROI: for data on radiotherapy centres, the set of indicators proposed by Cionini et al. (R&O 2007), and for data at the country level, the Australasian ROI (2011). Results The overall response ratio was 66.3%, but for the Russian Federation, it was 24%. Analysis of the results provided an update of current infrastructure in terms of radiotherapy and supporting equipment in each country. There are 246 RT centres operating 262 linear accelerators and 343 cobalt-60 units. 61% of teletherapy machines are older than 10 years. The concept of multidisciplinary decision making usually involves successive patient referrals and consultations as opposed to multidisciplinary tumour board meetings. 56% of patients are discussed in multidisciplinary meetings. The ratio of curative/palliative treatments is 2.7. CT- based treatment planning is performed in 42.5% of patients, 21.5% of treatments involve the use of an MLC, 87% of centres use local clinical treatment guidelines, and 67% have QA/QC protocols, 42.7% of treatments use open fields. The mean number of fractions is 31 for curative, 14 for palliative and 23 for all treatments. The ratio of non-planned downtime vs. planned maintenance for linacs is 5:1, and 28.7% of centres use R&V systems. Split-course radiotherapy is practiced routinelly in all countries except Azerbaijan for H&N, cervical, prostate and lung cancers. The naming, task profile and education programmes of radiotherapy professionals are different than in the west. Conclusion Most countries need modernization of their RT infrastructure coupled with adequate staffing numbers and education programmes. Some radiotherapy practices and techniques differ significantly from those practiced in western countries. Radiation oncology training programmes need expansion and update. The profession of medical physics is officially recognized in the Russian Federation only, while the profession of RTT is not recognized and there are no formal education programmes. EP-1679 Prospective survey regarding a mobile application-based concept for supportive care in radiotherapy R.A. El Shafie 1,2 , N. Bougatf 1,2,3 , J. Debus 1,2,3,4 , T. Machmer 5 , N.H.

The present survey aims to assess acceptance and possible benefits of a mobile application-based concept for supportive care of patients undergoing radiotherapy.
