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.

Multicenter Study
The influence of anesthesia-controlled time on operating room scheduling in Dutch university medical centres.
Predicting total procedure time (TPT) entails several elements subject to variability, including the two main components: surgeon-controlled time (SCT) and anesthesia-controlled time (ACT). This study explores the effect of ACT on TPT as a proportion of TPT as opposed to a fixed number of minutes. The goal is to enhance the prediction of TPT and improve operating room scheduling. ⋯ Efficient operating room (OR) management demands the accurate prediction of the times needed for all components of care, including SCT and ACT, for each surgical procedure. Supported by an extensive dataset from six UMCs, we advise grossing up the SCT by 33% to account for ACT (revised prediction of TPT = SCT × 1.33), rather than employing a methodology for predicting ACT based on a fixed number of minutes. This recommendation will improve OR scheduling, which could result in reducing overutilized OR time and the number of case cancellations and could lead to more efficient use of limited OR resources.
