We wanted to evaluate factors associated with high costs after allogeneic haematopoietic SCT (HSCT). We collected all in-patient and outpatient costs during the first year after HSCT over 5 years, from 2003 to 2007. Mean 1-year costs per patient were \[euro]141,493 (95% confidence interval (95% CI)=125,019-157,967). Patients treated with non-myeloablative conditioning (NMC) had reduced costs, but patients treated with reduced-intensity or myeloablative conditioning had similar 1-year costs. Multivariate analysis showed that increased 1-year costs were seen in post-transplant complications: rejection (relative hazard (RH) 1.24, P<0.001), acute GVHD of grades III-IV (1.31, P<0.001) and invasive fungal infection (1.15, P=0.02). In addition, increased costs were associated with re-transplantation (1.21, P=0.001), mesenchymal stem-cell therapy (1.26, P<0.001), unrelated donor transplants (1.20, P=0.002) and the need for G-CSF treatment due to poor engraftment (1.12, P=0.047). In patients without any of these risk factors, mean 1-year costs were \[euro]84,773 (95% CI=71,145-98,400) (n=51). With three risk factors, the cost increased to \[euro]249,775 (95% CI=166,824-332,727) (n=14). To conclude, major complications increased the costs of HSCT. Unrelated donor transplants were more expensive than HLA-identical sibling transplants. Costs were reduced in patients treated with NMC.
