Coagulopathy is associated with massive transfusion in trauma, yet most clinical scores to predict this end point do not incorporate coagulation assays. Previous work has identified that shock increases circulating tissue plasminogen activator (tPA). When tPA levels saturate endogenous inhibitors, systemic hyperfibrinolysis can occur. Therefore, the addition of tPA to a patient's blood sample could stratify a patients underlying degree of shock and early coagulation changes to predict progression to massive transfusion. We hypothesized that a modified thrombelastography (TEG) assay with exogenous tPA would unmask patients' impending risk for massive transfusion. ⋯ The tPA-TEG identifies trauma patients who require massive transfusion efficiently in a single assay that can be completed in a shorter time than other scoring systems, which has improved performance when combined with international normalized ratio. This new method is consistent with our understanding of the molecular events responsible for trauma-induced coagulopathy.

Post-discharge surgical care fragmentation is defined as readmission to any hospital other than the hospital at which surgery was performed. The objective of this study was to assess the impact of fragmented readmissions within the first year after orthotopic liver transplantation (OLT). ⋯ Post-discharge fragmentation significantly increases the risk of both 30-day mortality and subsequent readmission after a readmission in the first year after OLT. More inpatient visits before a readmission and less time elapsed from index surgery increase the odds of an adverse event after discharge from a fragmented readmission. These parameters could guide transfer decisions for patients with post-discharge fragmentation.

Patients diagnosed with a malignancy must decide whether to travel for care at an academic center or receive treatment at a nearby hospital. Here we examine differences in demographics, treatment, and outcomes of those traveling to academic centers for their care vs those not traveling, as well as compare travel for an aggressive vs indolent malignancy. ⋯ There are improvements in both quality and survival for those traveling to academic centers for their cancer care. In the case of PTC, this difference in quality did not affect overall survival. In PDAC, however, differences in quality translated to a survival advantage.

Aorto-enteric fistulas (AEF) represent a lethal subset of aortic graft infections. The optimal management of AEF remains unclear. We aimed to identify predictors of morbidity and mortality. ⋯ Over 20 years, approximately 50% of patients with AEF repairs died within 60 days. Gastrointestinal complications increase the risk of mortality more than 3-fold, representing an attractive surgically modifiable risk factor. Future multicenter studies are required to clarify optimal methods of arterial and GI reconstruction in AEF.
