The FMEA provided a useful method for evaluating the errors detected in the PTPCR. The FMEA results and the planning compliance rate could help us to improve the quality of treatment planning and to ensure the patient safety during radiation therapy.

PO-2309 A Pilot Initiative Using Telemedicine in Online Reviewing of CBCT For Stereotactic Radiation Therapy

1 National University Cancer Instituite Singapore, National University Health System, Radiation Oncology, Singapore, Singapore Purpose or Objective On-site to review and approval of the cone-beam computed tomography prior to the radiation delivery has been the usual practice. Remote review using telemedicine1,2 was formulated to reduce waiting time and travel time. The COVID-19 pandemic made on-site review increasingly challenging due to team segregation and movement cessation between hospitals had to be imposed. A pilot study was conducted to quantify the benefits of using telemedicine for online reviewing and approval of cone-beam computed tomography prior to stereotactic ablative radiation therapy delivery from March 2020 to December 2021. 74.9 % of the patients (212 out of 283) receiving stereotactic radiation therapy benefited from this new initiative. The aim of the study is to quantify the realized time savings and utilization of appointment slots for patients. Materials and Methods - Baseline data of patients received stereotactic body radiation therapy, stereotactic fractionated radiation therapy to brain and stereotactic radiosurgery to brain were obtained. initiative - Explore the options of secured network, speed of network, suitable mobile devices and its immobilization gear to allow better viewing of cone-beam computed tomography - Establish the workflow and work process especially radiation oncologists stationed off-site - Reduce time spent for patients in the department - Reduce time wastage for radiation oncologists to travel between hospitals - Consensus among the radiation oncologists for the

- Improve appointment allocation for patients - Increase radiation oncologists’ consultation slots - Improve radiation oncologists’ job satisfaction

Results There are 162 out 168 patients receiving stereotactic radiation therapy to the body, 50 out of 97 receiving stereotactic radiation therapy to the brain trial under the initiative. Baseline data was collected and patients often spend an average of 60 minutes in the department on the day of their treatment. The median time patient spent was reduced to 45 minutes. Prior the intervention, radiation oncologists have to travel between hospitals and be on-site to view and approve the cone- beam computed tomography and often delay at the other centre’s clinics, weather, road conditions are causes of the delay to be on-site. Intervention to improve workflow was implemented with the introduction of using telemedicine for viewing and approval of cone-beam computed tomography.
