[New crossmatch procedure: computer crossmatch experience in a blood service division]

Abstract

We established a computer crossmatch system in our hospital to commence 24-hour-a-day blood services. About 97% of red blood products were shipped using this system. Among them, only one patient developed a mild delayed hemolysis. ABO-mismatched transfusion or release of incompatible blood components was not reported at all. Since the turnaround time is shortened, cost reductions were achieved by reductions in blood units tied up in the crossmatched blood inventory, leading to reduced blood ordering.
