Effects of a restrictive blood transfusion protocol on acute pediatric burn care

Background Blood transfusion is costly and associated with various medical risks. Studies in critically ill adult and pediatric patients suggest that implementation of more restrictive transfusion protocols based on lower threshold hemoglobin concentrations can be medically and economically advantageous. The purpose of this study was to evaluate the implications of a hemoglobin threshold change in pediatric burn patients. Methods We implemented a change in hemoglobin threshold from 10 to 7 g/dL and compared data from patients before and after this protocol change in a retrospective review. Primary endpoints were hemoglobin concentration at baseline, before transfusion, and after transfusion; amount of blood product administered; and mortality. Secondary endpoints were the incidence of sepsis based on the American Burn Association physiological criteria for sepsis and mean number of septic days per patient. All endpoint analyses were adjusted for relevant clinical covariates via generalized additive models or Cox proportional hazard model. Statistical significance was accepted at p 0.05) were comparable between groups. The group transfused based on the more restrictive hemoglobin threshold had lower hemoglobin concentrations before and after transfusion throughout acute hospitalization, received lower volumes of blood during operations (pre: 1012 mL, post: 824 mL; p
