Predictors of health-related quality of life over time among pediatric hematopoietic stem cell transplant recipients.

Background: Advances in hematopoietic stem cell transplantation (HSCT) have contributed to increased survival for pediatric patients. However, there are inconsistent findings regarding the impact of HSCT on health-related quality of life (HRQOL) outcomes for children. This study aimed to establish trajectories of HRQOL following HSCT and identify predictors of the HRQOL course.

Procedure: Ninety caregivers of a child who received HSCT (mean age = 6.42 years) for various oncologic, immunologic, and metabolic conditions completed questionnaires regarding family psychosocial functioning and child HRQOL at the time of discharge from HSCT and follow-up HRQOL at four additional time points.

Results: There was a significant change in overall HRQOL in 3 months postdischarge, with the greatest improvement in physical functioning. Caregiver stress and social support, and child psychosocial problems predicted changes in HRQOL over time.

Conclusions: These results point to potentially modifiable factors that are related to the course of HRQOL following HSCT, and interventions aimed at these factors should be implemented.
