Multicenter Study Comparative Study
Transfusion reactions: a comparative observational study of blood components produced before and after implementation of semiautomated production from whole blood.
A semiautomated method of component production from whole blood was implemented at Canadian Blood Services. To assess safety of the new components, the frequency of adverse transfusion events (ATEs) to platelet components (PCs) and red blood cell (RBCs) produced before and after implementation of the new method was surveyed and compared. ⋯ The change in manufacturing method was associated with lower reaction rates to SAGM RBCs than to AS-3 RBCs. Pooled BC PLTs were noninferior to random-donor PRP PLTs with respect to ATEs.
