AbstractAllogeneic hematopoietic cell transplantation (HCT) is a curative option for patients with acute leukemia and myelodysplastic syndromes (MDS) but is associated with significant cost. Compared with children (age <15 years), adolescents and young adults (AYA; age 15 to 39 years) undergoing HCT have an increased risk for transplantation-related complications. However, whether such complications translate into increased resource utilization and costs during HCT remains unknown. Therefore, we conducted a multicenter database study using the Pediatric Health Information System database, an administrative database containing resource utilization data from 49 US tertiary children's hospitals to compare inpatient costs and resource utilization in children and AYA undergoing HCT for acute leukemia and MDS. The International Classification of Diseases, Ninth Revision, Clinical Modification codes were used to identify HCT recipients and transplantation-related complications occurring up to 1 year post-HCT. We identified 1693 HCT recipients at pediatric centers between January 2010 and September 2014. Eighty percent of the total costs (from admission for HCT up to 1 year post-HCT) occurred during the initial transplantation admission. During initial admission, although AYA and children had a similar median length of stay (LOS) of 43 days, AYA incurred significantly greater adjusted costs ($338,458 versus $275,723; P < .001) and costs per hospital day ($7122 versus $5838; P < .001). Median total costs and costs per day during subsequent time periods post-HCT were also significantly greater in the AYA group. In multivariable analysis, increasing age at HCT, LOS, use of cord blood or an unrelated donor, occurrence of any graft-versus-host disease, infection, and use of dialysis or mechanical ventilation were significant drivers of increased cost at initial admission. In conclusion, allogeneic HCT for acute leukemia and MDS is associated with higher costs in AYA recipients than in children. Therefore, directing efforts and resources aimed at reducing HCT-related costs may be advantageous in this high-risk group.Copyright © 2019 American Society for Blood and Marrow Transplantation.
