A pre and post-test was developed comprising of 12 questions in order to assess the trainee’s understanding of the knowledge of basic quality concepts deliberated in the lecture. The intent of tests was to provide qualitative feedback about the trainee’s knowledge and understanding of these processes. A total of 25 trainees (8 post graduate residents, 9 trainee medical physicists, 8 RTTS) participated. The class was led by a senior faculty who delivered a lecture and moderated the interactive discussion. Results There was an open and constructive interaction among the trainees during all four phases of this evaluation. Changes in trainee’s knowledge and understanding was positive. The pretest scores of all 12 questions varied from 8% to 72%. This trend was positively changed to a score ranging from 84-100%. Conclusion The pretest survey results showed that most trainees have less than expected practical knowledge of healthcare quality concepts. Our team would recommend introduction of a well-constructed module for inclusion in these three training programs which can fill this knowledge gap.

Material and Methods With a median age of 67 years (range 45-89 years), 69 patients (56 women and 13 men) were enrolled in a prospective analysis between April 2015 and March 2018. 111 treatments were performed due to enrollment of patients affected with more than one location. Patients analyzed presented finger joints osteoarthritis, rhizarthrosis, wrist osteoarthritis, gonarthrosis, shoulder and hip arthritis or spondyloarthrosis. All patients underwent CT-based simulation. Planning target volume (PTV) contoured on CT scan included painful joint. Treatment was delivered in a LINAC and daily verified with orthogonal X-ray. 6 Gy were delivered in single fractions of 1 Gy every other day, however, if complete response wasn´t reached, a second course of identical characteristics was delivered 6-8 weeks after finishing the first course. Pain was measured before and after radiotherapy using the visual analogue scale (VAS). Long term response was also evaluated with the functional scale proposed by von Pannewitz and determining the variation in the daily analgesic drugs intake. Results Most prevalent locations were fingers (47%), knees (30%), and shoulders (14%). With a median follow-up of 7 months (1-28 months), 52% of patients referred improvement, however, objectively, 74% of treated patients experienced pain relief in different degrees. According to the VAS scale, pain reported was greater or equal to 7 in 82% of the patients before treatment and 88% of this group showed response. After treatment, half of all patients showed grade 3 or less of pain even though, 86% of these patients had pain greater than 7 before treatment. 42% of the patients needed to take less analgesia after

elucidated and validated. The learning concepts included history, physical examination, imaging interpretation, staging, as well as anatomy, epidemiology, pertinent literature, differential diagnosis, prognostication, radiation treatment planning, summarizing, and patient and peer communication skills. Clinical vignettes were then designed, in collaboration with a virtual patient education expert, to mimic the clinical presentation and evolution of a typical patient for three common oncologic emergencies: spinal cord compression, superior vena cava syndrome, and hemorrhage. Results 3 virtual cases were developed: spinal cord compression, superior vena cava syndrome, and tumour-induced hemorrhage. Each case includes 25 to 30 screens to progress through, with a total estimated completion time of 30 to 45 minutes. Each node branches out to provide a detailed answer and explanation of the key concept. Figures were included to mimic real patients and provide a more authentic learning environment. The modules also included quantitative pre- and post- testing with multiple choice questions, true or false, fill in the blank, and text response. The cases were then transcribed onto a virtual patient simulation platform. The platform is accessible to the learner through his or her own personal sign-on. Following completion of the module, a report is generated for each individual learner to track all responses and can be used as an assessment tool. Qualitative data will also be collected regarding user- friendliness and learner satisfaction. The pilot test showed an increase of 27% in the pre-to- post-test results in a cohort of 9 residents. The mean pre- test result of 64% increased to a mean post-test result of 91% (range: 70-100%) after completing the three modules. Conclusion Virtual patient cases can be used for the management of oncologic emergencies and can be done on a simulation- based learning platform. The modules can be used as an assessment and leaning tool for junior residents. The preliminary results of the pilot-test show a significant improvement in competence after completion of the three modules. EP-1669 Evaluation of Healthcare Quality Concepts in Radiation Oncology PG Training Programs M. Uddin Karim 1 , A.N. Abbasi 2 , B.M. Qureshi 2 , N. Ali 2 , A. Hafiz 2 , B. Mir Khan 2 1 Aga Khan University Hospital, Oncology, Karachi, Pakistan ; 2 Aga Khan University, Oncology, Karachi, Pakistan Purpose or Objective Radiation Oncology (RO) Trainees (Post graduate Residents, Trainee medical physicists, Trainee Radiation Therapy Technologists RTTs) face ongoing challenges associated with the everyday reality of having demanding clinical workloads. They are expected to contribute to patient safety and quality improvement in RO, but prior studies suggest that training for this may be inadequate. In order to inculcate the basic concepts of healthcare quality in all three training programs, an evaluation of awareness was performed in our department. As per our team’s deliberations, this evaluation will allow treatment idea sharing of quality systems and processes after training. As healthcare providers, these future carers will be looking after their professional development needs. It is important to identify weaker links and to learn core concepts of quality. Material and Methods An orientation lecture was designed to give a practical overview of quality RO practice concepts. The content was streamlined to fit into a single day activity and delivered through a lecture followed by interactive group discussion of the concepts.
