BACKGROUND: Using the recent Consensus Panel recommendations, we sought to describe the incidence of transfusion‐related acute lung injury (TRALI) and transfusion‐associated circulatory overload (TACO) in critically ill patients.

STUDY DESIGN AND METHODS: Consecutive patients at four intensive care units (ICUs) who did not require respiratory support at the time of transfusion were identified with custom electronic surveillance system that prospectively tracks the time of transfusion and onset of respiratory support. Respiratory failure was defined as the onset of noninvasive or invasive ventilator support within 6 hours of transfusion. Experts blinded to specific transfusion factors categorized the cases of pulmonary edema as permeability edema (suspected or possible TRALI) or hydrostatic edema (TACO) according to predefined algorithm. In a nested case‐control design, transfusion variables and lung …
