Multicenter Study
Electronic health record surveillance algorithms facilitate the detection of transfusion-related pulmonary complications.
Transfusion-related acute lung injury (TRALI) and transfusion-associated circulatory overload (TACO) are leading causes of transfusion-related mortality. Notably, poor syndrome recognition and underreporting likely result in an underestimate of their true attributable burden. We aimed to develop accurate electronic health record-based screening algorithms for improved detection of TRALI/transfused acute lung injury (ALI) and TACO. ⋯ Electronic screening algorithms have shown good sensitivity and specificity for identifying patients with TRALI/transfused ALI and TACO at our institution. This supports the notion that active electronic surveillance may improve case identification, thereby providing a more accurate understanding of TRALI/transfused ALI and TACO epidemiology.

Comparative Study Clinical Trial
Transfusion of banked red blood cells and the effects on hemorrheology and microvascular hemodynamics in anemic hematology outpatients.
The aim of this study was to investigate the effects of red blood cell (RBC) transfusion on the hemorrheologic properties and microcirculatory hemodynamics in anemic hematology outpatients receiving 2 to 4 RBC units of either "fresh" (leukoreduced storage for less than 1 week) or "aged" (leukoreduced storage for 3-4 weeks) RBCs. ⋯ Storing leukoreduced SAGM-suspended RBCs for 3 to 4 weeks did not affect their ability to improve hemorrheologic properties and microcirculatory hemodynamics in our small group of anemic hematology outpatients. Larger studies are needed to confirm this finding.

Randomized Controlled Trial Multicenter Study Comparative Study
Plasma transfusion in liver transplantation: a randomized, double-blind, multicenter clinical comparison of three virally secured plasmas.
The clinical equivalence of plasma treated to reduce pathogen transmission and untreated plasma has not been extensively studied. A clinical trial was conducted in liver transplant recipients to compare the efficacy of three plasmas. ⋯ Compared to both Q-FFP and S/D-FFP, use of MB-FFP was associated with a moderate increase in volume transfused, partly explained by a difference in unit volume and bleeding risk factors. Q-FFP was associated with fewer units transfused than either S/D-FFP or MB-FFP.

A systematic review of randomized controlled trials and observational studies assessing platelet (PLT) transfusion therapy identified gaps in the descriptions of trial design, variables of the PLT products transfused, and outcomes. We aimed to systematically develop a reporting guideline to aid in designing, reporting, and critiquing PLT trials. ⋯ Use of the Delphi method was successful in finding consensus on items to include in reports of a clinical PLT transfusion study. The final checklist and explanatory guide will be useful for authors and editors to improve the reporting of PLT transfusion trials.

Variables of hemostasis before surgery might indicate an elevated risk of bleeding. We determined hemostasis tests and standardized bleeding history and their association with bleeding and transfusion requirements in cardiopulmonary bypass (CPB) surgery. ⋯ A standardized bleeding history may help to identify patients undergoing CPB surgery whose risk of bleeding is elevated. ADP-induced MEA appears to predict postoperative bleeding and PC transfusion requirements, while AA-induced MEA and preoperative Hb indicate the need for RBCs. The time of aspirin withdrawal before surgery influences perioperative blood loss and PC transfusion.
