The overall transfusion rates for spinal fusion remained stable in the US during the last decade. During the last decade, the ALBT rate increased, whereas the PR-ABT rate decreased in patients who underwent spinal fusion in US hospitals. The overall transfusion rate may be reduced by utilizing a patient blood management program, targeting the subgroups of patients with the high ALBT rate.
