This article reports a single‐center randomized clinical trial that evaluated the effect of early integrated specialty palliative care on patient‐ and caregiver‐reported outcomes in patients with newly‐diagnosed, incurable cancers. It was hypothesized that caregivers of patients assigned to early integrated palliative care would report lower psychological distress and better quality of life compared with caregivers of patients assigned to usual oncology care.
Purpose
Inpatient palliative care integrated with transplant care improves patients’ quality of life (QOL) and symptom burden during hematopoietic stem-cell transplant (HCT). We assessed patients’ mood, post-traumatic stress disorder (PTSD) symptoms, and QOL 6 months post-transplant.
Methods
We randomly assigned 160 patients with hematologic malignancies who underwent autologous or allogeneic HCT to inpatient palliative care integrated with transplant care (n = 81) or transplant care alone (n = 79). At baseline and 6 months post-transplant, we assessed mood, PTSD symptoms, and QOL with the Hospital Anxiety and Depression Scale and Patient Health Questionnaire, PTSD checklist, and Functional Assessment of Cancer Therapy-Bone Marrow Transplant. To assess symptom burden during HCT, we used the Edmonton Symptom Assessment Scale. We used analysis of covariance while controlling for baseline values to examine intervention effects and conducted causal mediation analyses to examine whether symptom burden or mood during HCT mediated the effect of the intervention on 6-month outcomes.
Results
We enrolled 160 (86%) of 186 potentially eligible patients between August 2014 and January 2016. At 6 months post-transplant, intervention participants reported lower depression symptoms on the Hospital Anxiety and Depression Scale and Patient Health Questionnaire (adjusted mean difference, −1.21 [95% CI, −2.26 to −0.16; P = .024] and −1.63 [95% CI, −3.08 to −0.19; P = .027], respectively) and lower PTSD symptoms (adjusted mean difference, −4.02; 95% CI, −7.18 to −0.86; P = .013), but no difference in QOL or anxiety. Symptom burden and anxiety during HCT hospitalization partially mediated the effect of the intervention on depression and PTSD at 6 months post-transplant.
Conclusion
Inpatient palliative care integrated with transplant care leads to improvements in depression and PTSD symptoms at 6 months post-transplant. Reduction in symptom burden and anxiety during HCT partially accounts for the effect of the intervention on these outcomes.
