Background Despite its established benefits, palliative care (PC) is rarely utilized for hematopoietic stem cell transplant (HSCT) patients. We sought to examine transplant physicians’ perceptions of PC. Methods We conducted a cross‐sectional survey of transplant physicians recruited from the American‐Society‐for‐Blood‐and‐Marrow‐Transplantation. Using a 28‐item questionnaire adapted from prior studies, we examined physicians’ access to PC services, and perceptions of PC. We computed a composite score of physicians’ attitudes about PC (mean = 16.9, SD = 3.37) and explored predictors of attitudes using a linear mixed model. Results 277/1005 (28%) of eligible physicians completed the questionnaire. The majority (76%) stated that they trust PC clinicians to care for their patients, but 40% felt that PC clinicians do not have enough understanding to counsel HSCT patients about their treatments. Most endorsed that when patients hear the term PC, they feel scared (82%) and anxious (76%). Nearly half (46%) reported that the service name ‘palliative care’ is a barrier to utilization. Female sex (β = 0.85, P = .024), having <10 years of clinical practice (β = 1.39, P = .004), and perceived quality of PC services (β = 0.60, P < .001) were all associated with a more positive attitude towards PC. Physicians with a higher sense of ownership over their patients’ PC issues (β = ‐0.36, P < .001) were more likely to have a negative attitude towards PC. Conclusions The majority of transplant physicians trust PC, but have substantial concerns about PC clinicians’ knowledge about HSCT and patients’ perception of the term ‘palliative care’. Interventions are needed to promote collaboration, improve perceptions, and enhance integration of PC for HSCT recipients.
