105 Background: Radiation oncologists are frequently involved in providing palliative and supportive care (PSC) for patients with advanced cancers through delivery of palliative radiation. Whether they are confident in their ability to assess and initiate treatments for pain, non-pain, and psychosocial distress is unknown. The American Society for Radiation Oncology (ASTRO) surveyed its practicing members in the United States on self-assessment of their primary PSC skills, and access to continuing medical education on PSC. Methods: We electronically surveyed 4,093 practicing radiation oncologists in the United States. The survey consisted of 17-questions in five sections: demographics, PSC training, domains of PSC, perceived barriers as a radiation oncologist to initiate advanced care planning, and discussion on prognosis. Results: The majority (91%) of radiation oncologists surveyed believe PSC is an important competency for radiation oncologists. Most radiation oncologists reported that they are moderately confident in their ability to assess and manage pain and GI symptoms but less confident in their ability to manage anorexia, anxiety, and depression. Despite areas of decreased confidence, a large number (42%) of radiation oncologists do not receive any additional PSC education beyond their residency training. Lastly, a perceived fear of upsetting referring medical oncologists and lack of clinic time are concerns for radiation oncologists who may want to initiate goals of care/advance care planning discussions with patients and their families. Conclusions: Radiation oncologists are more confident in their ability to assess and manage pain than in their ability to manage depression, anxiety, anorexia, and fatigue. There is a need for increasing continuing medical educational efforts in PSC for practicing radiation oncologists, and strengthening PSC training in residency programs.
