Caring for the dying is a core competency for oncologists, yet the quality of oncology fellowship training in end-of-life (EOL) care has not been assessed. A convenience sample of physicians attending the 2004 annual meeting of the American Society of Clinical Oncology responded to a 112-item questionnaire that assessed fellows' knowledge and education about EOL care. Of the 120 respondents, 107 (89%) rated caring for dying patients as"quite" or "very important. "Forty-two percent of the fellows rated the overall quality of teaching EOL care in their fellowship as "very good" or "excellent," whereas 23% gave such ratings to EOL teaching in fellowship (P < or = 0.001). Fellows viewed attending oncologists as having more expertise in dealing with acute complications of cancer (eg, managing spinal cord compression, 78%) than in delivering EOL care (eg, managing pain, 54%; P < 0.001). Fellows also were more likely to have received observation and feedback on bone marrow biopsies than on EOL discussions. Knowledge about key EOL care topics was poor; only 31% correctly performed an opioid conversion. Oncology fellows described deficiencies in training on EOL issues;they may benefit from improved education on EOL topics.
