Implementation of a light therapy team to administer photobiomodulation therapy: A standardized protocol to prevent and treat oral mucositis in the pediatric hematopoietic stem cell transplant population.

BACKGROUND

Oral mucositis (OM) is a painful and common complication of hematopoietic stem cell transplant (HSCT). The Children's Oncology Group recently published guidelines recommending photobiomodulation (PBM) for preventing and treating OM in pediatric HSCT patients. However, this is a rarely used intervention in pediatric hospitals.

PROCEDURE

Patients undergoing allogeneic HSCT, or autologous HSCT for a neuroblastoma diagnosis, had PBM administered from the first day of conditioning to transplant Day +20. We successfully developed a standardized treatment protocol and workflow to ensure consistent and uniform delivery of PBM. In addition, clinical patient data were compared before and after PBM implementation.

RESULTS

The administration of PBM at our center was feasible, but required dedicated staff. A registered nurse (RN) was determined to be the best fit to deliver PBM. Sixty-two patients received PBM from October 2022 to September 2023; patients from 2021 before PBM implementation were used for comparison. Patients receiving PBM were more likely (p = .03) to engage in teeth brushing (56/62 = 90%) compared to baseline (61/81 = 75%). Mean days of OM decreased from 11.3 to 9 days; patients who received PBM were less likely (p < .001) to be discharged on total parental nutrition (TPN) (11/62 = 18%) compared to baseline (50/82 = 61%). OM-related supportive care costs (TPN and patient-controlled anesthesia [PCA]) were lower (p = .02) for those who received PBM (median cost = $31,229.87 vs. $37,370.66).

CONCLUSION

PBM, as the standard of care in the pediatric HSCT population, is safe, feasible, and well-tolerated. At our center, a dedicated RN was critical to providing standardized treatment and ensuring sustainability.
