Effective handoffs of care are critical for maintaining patient safety and avoiding communication problems. Using the flow disruption observation technique, we examined transitions of care along the trauma pathway. We hypothesized that more transitions would lead to more disruptions, and that different pathways would have different numbers of disruptions. ⋯ Transitions in trauma care are vulnerable to systems problems and human errors. Coordination problems predominate as the cause. Sicker, time-pressured, and more at-risk patients are more likely to experience problems. Safety practices used in motor racing and other industries might be applied to address these problems.

High-dose vancomycin is increasingly prescribed for critically ill trauma patients at risk for methicillin-resistant Staphylococcus aureus pneumonia. Although trauma patients have multiple known risk factors for acute kidney injury (AKI), a link between vancomycin and AKI or mortality has not been established. We hypothesize that high vancomycin trough concentration (VT) after trauma is associated with AKI and increased mortality. ⋯ AKI is common in trauma patients who receive intravenous vancomycin. A supratherapeutic trough level of >20 mg/L is an independent predictor of AKI and mortality in trauma patients.

As the population ages, trauma in the elderly is an increasingly recognized source of elderly morbidity. However, previous reviews on the topic provide only broad recommendations. The purpose of this study was to examine the elderly recidivist cohort at an urban trauma center for mechanisms of repeat injury. ⋯ The overall recidivism rate in the elderly population is low. Nevertheless, recidivists were more susceptible to penetrating trauma, ATV/motorcycle collisions, and possibly bicycle accidents. These findings can help design counseling initiatives and injury prevention programs that target specific elderly trauma patients.

Information regarding the use of negative pressure wound therapy (NPWT) in the pediatric population is limited. Because of adverse outcomes in adult patients, the Food and Drug Administration issued a warning in 2011 about the use of NPWT in infants and children. ⋯ NPWT is an effective adjunct in wound healing and closure in the pediatric population, with no mortality ascribed to NPWT. Also, the complication rates were low.

Tumor necrosis factor-α (TNF-α), a cytotoxic cytokine, induces endothelial cell barrier dysfunction and microvascular hyperpermeability, leading to tissue edema, a hallmark of traumatic injuries. The objective of the present study was to determine whether B-cell lymphoma-extra large (Bcl-xL), an antiapoptotic protein, would regulate and protect against TNF-α-mediated endothelial cell barrier dysfunction and microvascular hyperpermeability. ⋯ Our results have demonstrated the protective effects of recombinant Bcl-xL protein against TNF-α-induced endothelial cell adherens junction damage and microvascular endothelial cell hyperpermeability. These findings support the potential for Bcl-xL-based drug development against microvascular hyperpermeability and tissue edema.
