Insights
Allogeneic hematopoietic stem cell transplants (HSCTs) for pediatric acute lymphoblastic leukemia incur substantial healthcare resource utilization and direct costs, particularly in the first year post-transplant.
Area of Science:
- Hematology
- Pediatric Oncology
- Health Economics
Background:
- Acute lymphoblastic leukemia (ALL) is a common childhood cancer.
- Allogeneic hematopoietic stem cell transplant (HSCT) is a curative treatment option for high-risk ALL.
- Understanding the long-term healthcare burden of HSCT is crucial for resource planning.
Purpose of the Study:
- To evaluate the 5-year healthcare resource utilization (HRU) and direct payer costs.
- To analyze HSCT outcomes in pediatric patients with acute lymphoblastic leukemia (ALL).
Main Methods:
- Retrospective analysis of two large US administrative databases.
- Inclusion of 209 pediatric patients diagnosed with ALL who underwent allogeneic HSCT.
- Description of HRU and costs for up to 5 years post-HSCT.
Main Results:
- Substantial HRU and direct costs were observed following allogeneic HSCT.
- The first year post-HSCT exhibited the highest costs (US$683,099) and HRU (49 outpatient visits, 29 lab visits, 68 inpatient days).
- Significant healthcare costs persisted in the subsequent years after HSCT.
Conclusions:
- Allogeneic HSCT for pediatric ALL is associated with considerable HRU and direct financial costs.
- The initial year post-transplant represents the period of highest resource intensity and expenditure.
Aim:
To assess the 5-year healthcare resource utilization (HRU) and direct payer costs following allogeneic hematopoietic stem cell transplants (HSCTs) in acute lymphoblastic leukemia pediatric patients using data from two large US administrative databases.
Patients & Methods:
Among the 209 patients with acute lymphoblastic leukemia, HRU and costs were described over the up to 5 years after the HSCT.
Results:
HRU and costs following the HSCTs were substantial. The highest average costs and most intensive HRU were observed within the first year following the HSCTs (49 outpatient visits; 29 laboratory service visits; 68 inpatient days), with a first year cost of US$683,099 and substantial costs over the following years.
Conclusion:
HRU and direct costs associated with allogeneic HSCTs are substantial.
