Multimodal psychosocial intervention for family caregivers of patients undergoing hematopoietic stem cell transplantation: A randomized clinical trial

Background: Caregivers of patients undergoing hematopoietic stem cell transplantation (HCT) experience an immense caregiving burden before, during, and after HCT.

Methods: We conducted an unblinded, randomized trial of a psychosocial intervention (BMT-CARE) for caregivers of patients undergoing autologous and allogeneic HCT at Massachusetts General Hospital. Caregivers were randomly assigned to BMT-CARE or usual care. BMT-CARE was tailored to the HCT trajectory and integrated treatment-related education and self-care with cognitive-behavioral skills to promote coping. Caregivers assigned to BMT-CARE met with a trained interventionist (a psychologist or a social worker) in person, via telephone, or via videoconferencing for 6 sessions starting before HCT and continuing up to day +60 after HCT. The primary endpoint was feasibility, which was defined as at least 60% of eligible caregivers enrolling and completing 50% or more of the intervention sessions. We assesed caregiver quality of life (QOL; Caregiver Oncology Quality of Life Questionnaire), caregiving burden (Caregiver Reaction Assessment), psychological distress (Hospital Anxiety and Depression Scale), self-efficacy (Cancer Self-Efficacy Scale-Transplant), and coping (Measures of Current Status) at baseline and 30 and 60 days after HCT. We used mixed linear effect models to assess the effect of BMT-CARE on outcomes longitudinally.

Results: We enrolled 72.5% of eligible caregivers (100 of 138), and 80% attended 50% or more of the intervention sessions. Caregivers randomized to BMT-CARE reported improved QOL (B = 6.11; 95% CI, 3.50-8.71; P < .001), reduced caregiving burden (B = -6.02; 95% CI, -8.49 to -3.55; P < .001), lower anxiety (B = -2.18; 95% CI, -3.07 to -1.28; P < .001) and depression symptoms (B = -1.23; 95% CI, -1.92 to -0.54; P < .001), and improved self-efficacy (B = 7.22; 95% CI, 2.40-12.03; P = .003) and coping skills (B = 4.83; 95% CI, 3.04-6.94; P < .001) in comparison with the usual-care group.

Conclusions: A brief multimodal psychosocial intervention tailored for caregivers of HCT recipients is feasible and may improve QOL, mood, coping, and self-efficacy while reducing the caregiving burden during the acute HCT period.
