This retrospective observational study was performed to determine if the age of transfused units of red blood cells (RBCs) was related to mortality. The study included 31 transfused patients admitted to the intensive care unit during 1992 with severe sepsis (i.e., sepsis associated with organ dysfunction, hypoperfusion, or hypotension). ⋯ The authors concluded that the duration of storage of RBCs is directly related to the risk of mortality among transfused patients with severe sepsis. Recognizing the limitations of their small retrospective study that did not adjust for confounders, they also stated that further studies are needed to confirm or refute this association.
