Effectiveness of a Three-Stage Intervention in Reducing Caregiver Distress During Pediatric Hematopoietic Stem Cell Transplantation: A Randomized Controlled Trial.

More than one fourth of primary caregivers report clinically significant distress during the hematopoietic stem cell transplantation (HSCT) process. Providing early support to primary caregivers could reduce caregiver distress and improve the quality of life. This study examined the effects of a three-stage caregiver support intervention designed to reduce caregiver distress and improve quality of life during pediatric HSCT hospitalization. A two-group comparative study was conducted with repeated measures. Participants were randomly assigned to an intervention group or a control group. The intervention group received the support intervention 5 days before the transplant, 14 days after transplant, and 1 week before hospital discharge. The control group received standard support provided in the hospital ward. Measures were obtained at all three time points from self-report questionnaires, which were related to anxiety, depression, perceived stress, and quality of life. Findings indicated that primary caregivers in the intervention group (n = 22) reported significantly lower levels of perceived stress and higher levels of quality of life than the control group (n = 23) at 14 days after transplant. In the intervention group, caregiver distress significantly decreased from pretransplant through 14 days after transplant, while over the same period caregiver quality of life significantly increased. The intervention effectively changed the trend of distress and quality of life for caregivers of children during the process of HSCT and hospitalization. The findings of this study suggest that it is important to provide early targeted interventions at critical junctures for caregivers at risk of adverse outcomes.
