Background: Transfusions are an essential palliative tool in the stem cell transplant (SCT) population. Limited data exist regarding transfusion practices at end-of-life for SCT patients and whether these practices may limit enrollment in hospice. Methods: A retrospective chart review was conducted of deceased patients with hematologic malignancies who underwent SCT at an academic medical center from 2011 to 2015. The primary objective was to determine the difference between the dates of last transfusion and death in patients enrolled and not enrolled in hospice. A secondary objective was evaluation of the number of transfusions between groups. Data were compiled from a single electronic medical record. Descriptive analyses were performed. Days to last transfusion were analyzed using the Wilcoxon-Mann-Whitney test. Number of packed red blood cell (PRBC) transfusions and platelets transfusions on the last day were analyzed using Fisher and chi-squared tests, respectively. Results: A total of 633 SCT were performed from 2011 to 2015 including 39% (n = 245) allogeneic and 61% (n = 388) autologous transplants (n = 29 patients had 2 transplants). Mean ± SD age of SCT patients was 55 ± 13 years. As of January 2016, 20% (n = 119) of these SCT patients have died. Of those that died, 15% (n = 18) were enrolled in hospice. For SCT patients enrolled in hospice, the mean ± SD time of last blood transfusion from death was 42.3 ± 63.4 days, with mean ± SD 0.67 ± 0.77 units of PRBC’s and 0.72 ± 0.75 units of platelets administered. For SCT patients not enrolled in hospice, the mean ± SD time of last blood transfusion from death was 14.2 ± 47.9 days, with mean±SD total 0.69 ± 1.03 units of PRBC’s and 1.14 ± 1 units of platelets administered. Hospice patients had a statistically significant longer number of days until last blood transfusion compared to non-hospice patients (p < 0.001). There was no difference between SCT patients enrolled in hospice and not enrolled in PRBC transfusions (p = 0.069), but there was a significantly higher amount of platelet transfusions in patients not enrolled in hospice (p < 0.005). Conclusions: This data suggests that time to last transfusion may be a significant obstacle for SCT patients when enrolling in hospice, but requires further validation.
