Pathogen reduction technologies (PRTs) may induce storage lesion in platelet (PLT) concentrates. To investigate this, buffy coat PLTs (BCPs) in PLT additive solution (AS; SSP+) with or without Mirasol PRT (CaridianBCT Biotechnologies) were assessed by quality control tests and four-color flow cytometry. ⋯ PRT treatment of BCP in AS induced a minor initial PLT loss and enhanced metabolism and PLT activation. The clinical relevance for PLT function in vivo of these findings will be investigated in a clinical trial.

Trypanosoma cruzi, the etiologic agent of Chagas disease, is a potential threat to transfusion recipients in the United States. The cost-effectiveness of seven testing strategies was evaluated against no testing and hierarchically in incremental analysis. Donor-specific strategies included testing donors born in endemic countries, testing all donors a specific number of times, or testing all donors every time. Component-specific strategies are based on screening platelet-containing donations. ⋯ Selective T. cruzi screening generates nearly the same effectiveness as universal screening, but at a reduced cost. Outcomes and associated costs of Chagas disease take longer to materialize than the average life expectancy of transfusion recipients.

The purpose of this study was to evaluate the ability of uncrossmatched transfusions in the emergency department (ED) to predict early (< 6 hr) massive transfusion (MT) of red blood cells (RBCs) and blood components. ⋯ Patients receiving uncrossmatched RBCs in the ED are more than three times more likely to receive early MT of RBCs. Additionally, patients transfused with ED RBCs are more likely to receive 6 units or more of plasma and two or more apheresis PLT transfusions. Given these findings, ED transfusion of uncrossmatched RBCs should be considered a potential trigger for activation of an institution's MT protocol.

Red blood cell (RBC) product wastage in hospitals is reported to range from 0.1% to 6.7%. Wastage at our institution averaged 4.4% of 63,000 issued RBC products. Data indicated that approximately 87% of wasted RBC units were either individual units that were out of blood bank for more than 30 minutes (dispensed but not administered) or units packed in transport containers that had temperature indicators affixed to each unit. We hypothesized that Lean Sigma methodology could be used to reduce RBC wastage by 50%. ⋯ Lean Sigma methodology was an effective tool for reducing RBC wastage in a large academic hospital.
