Longitudinal Study on the Quality of Life of Pediatric Patients After Hematopoietic Stem Cell Transplantation and Its Influencing Factors

Objective: To longitudinally track the dynamic changes in the survival quality of pediatric patients after hematopoietic stem cell transplantation at different time points within 1 year post-transplantation, analyze the influencing factors of survival quality at each time point, identify independent risk factors that can be intervened, provide reference for medical staff to recognize survival quality problems early, guide the dynamic management of clinical survival quality, and formulate continuation care management plans.

Methods: This study adopted a repeated measurement study design. A total of 250 pediatric patients who underwent hematopoietic stem cell transplantation in three tertiary hospitals in Guangdong Province from August 2023 to December 2025 and met the research standards were selected as the research subjects. The "Childhood Health Assessment Questionnaire Transplant Module 3.0 Chinese Version" was used to evaluate the survival quality of the patients at six time points: 1 week before pre-treatment (T0), the day of stem cell infusion (T1), 1 month (T2), 3 months (T3), 6 months (T4), and 1 year (T5) after transplantation. Statistical methods for repeated measures were used to analyze the relevant information, and mixed-effect linear models were used to analyze the influencing factors of survival quality at the six time points, and to identify independent risk factors.
