ESTRO 2023

So far 194 Swedish professionals (clinical oncologists, medical physicists, RTT:s and others with an interest in radiotherapy have joined the association. The organisation has achieved an increasing interest and has contributed to a large number of activities from several stakeholders in Swedish radiotherapy and cancer care; the Swedish cancer association have in 2021 and 2022 assigned more than 11 million EURO for clinical research in radiation oncology; the government has financed a benchmarking project comparing radiotherapy in the Nordic countries; Swedish manufacturers of radiotherapy associated products have shown an increasing interest in collaboration; patient groups have joined the mission and are lobbying for a national strategy to form the future for radiotherapy in Sweden; the heads of Swedish oncology department support their staff to participate in ESTRO-meetings and SSOF has organised and plan additional scientific meetings covering the development in radiation oncology. Furthermore, media and patient advocates have helped to set focus on radiotherapy and revealed the emerging needs in Swedish radiotherapy. Conclusion Multiprofessional collaboration based on a framework as ESTRO:s five-point action plan seem to be a powerful tool to enhance national collaboration and create a focus on joint actions from several stakeholders.

PO-1100 Validity and feasibility study of direct observation of radiotherapy planning skills

1 ST Luke's Radiation Oncology Network, Radiation Oncology, Dublin, Ireland; 2 University of Dundee School of Medicine, Postgraduate Medicine, Dundee, United Kingdom Purpose or Objective Radiotherapy planning skill (RPS) is a fundamental skill for radiation oncologists. There is a dearth of research investigating the use of Direct Observation of Procedural skills (DOPS) for RPS. There are variations in the DOPS tools among different radiation oncology training programs internationally. The aim of this study was to examine the validity and feasibility of DOPS for RPS in the Irish post graduate training program. Materials and Methods This is a quantitative study aligned with the positivism paradigm. Data were collected using an online survey. All the trainers and trainees in the Irish postgraduate radiation oncology training program were invited to complete a survey questionnaire. Total population sample was used. To examine content validity, a potential checklist of 34 items was developed and responders were asked to rate each step according to its importance. Questionnaire included other questions related to the face validity and feasibility like the DOPS scoring system and frequency of need. The acquired data were analysed by descriptive statistics. Both Content validity ratio (CVR) and Content validity index (CVI) were calculated. Results Twenty three out of invited 47 trainers and trainees completed the survey questionnaire (13 trainers and 10 trainees). The items CVI and CVR for a potential 34 items checklist were calculated. An Updated checklist containing 16 items which met the validity threshold was created and achieved excellent validity (S-CVI and CVR 0.93 and 0.87 respectively). A minimum of 4 DOPS of RPS per year is considered feasible. There is an agreement to keep the scoring system for each step based the expected performance of the trainees according to their stage of training. However, there is no agreement on the global score. The majority recommended development of site specific DOPS tools. Conclusion This study showed the feasibility of DOPS. It illustrated acceptable quantity indices of content validity for a 16 item checklist for DOPS of RPS. Based on the study results, I recommend implementing an updated DOPS checklist with a minimum of 4 DOPS of RPS per year as formative assessment in the Irish radiation oncology postgraduate training program.

Failure Mode and Effect Analysis (FMEA) is a proactive methodology that allows to analyze a process and to evaluate the risk connected, regardless of whether an adverse event occurs. In this study, the simulation CT process was analyzed using FMEA approach by radiation oncologists (ROs) in training and was validated by expert ROs. Materials and Methods An eight-hours course, led by two clinical risk experts, was performed during the school of specialization in RO to illustrate the risk analysis approaches. During this course, the six ROs in training, helped by the two experts, performed a detailed process analysis of the CT simulation and evaluated the possible Failure Modes (FMs). For each FM, the estimated frequency of occurrence (O – range 1-4), the expected severity of the damage (S – range 1-5) and the detectability lack (D – range 1- PO-1101 FMEA of the simulation CT in a RT department: lesson learned by radiation oncologists in training
