Randomized Controlled Trial Multicenter Study
Non-Vitamin K Antagonist Oral Anticoagulants for the Treatment of Cerebral Venous Sinus Thrombosis: a Retrospective, Matched Cohort Analysis.
The management of cerebral venous sinus thrombosis (CVT) is a common problem facing vascular neurologists. American Heart Association/American Stroke Association guidelines suggest the use of heparin followed by vitamin K antagonists (VKAs) for anticoagulation in CVT. In recent years, the evidence base has solidified for the use of non-vitamin K antagonist oral anticoagulants (NOACs) in lower extremity deep vein thrombosis. Because data supporting their use in CVT are limited, with the strongest evidence comprising one randomized controlled trial of dabigatran, we sought to review our experience with NOACs in the treatment of CVT at a tertiary care center to address efficacy and safety. ⋯ The safety and efficacy results of NOAC use for CVT were similar to those for age-matched and sex-matched controls treated with VKAs, as well as historical published controls. Assessment of NOAC efficacy and safety in CVT in multicenter cohort studies and randomized controlled trials is warranted.

Prognostic Value of Hemorrhagic Brainstem Injury on Early Computed Tomography: A TRACK-TBI Study.
Traumatic brainstem injury has yet to be incorporated into widely used imaging classification systems for traumatic brain injury (TBI), and questions remain regarding prognostic implications for this TBI subgroup. To address this, retrospective data on patients from the multicenter prospective Transforming Research and Clinical Knowledge in TBI study were studied. ⋯ These findings suggest two groups of patients with brainstem injuries may exist with divergent recovery potential after TBI. These data support the notion that newer CT imaging classification systems may augment traditional clinical measures, such as GCS in identifying those patients with TBI and brainstem injuries that stand a higher chance of favorable outcome.

Prognostic Uncertainty in Critically Ill Patients with Traumatic Brain Injury: A Multicenter Qualitative Study.
Prognostic uncertainty is frequently cited as a barrier to communication between physicians and patients and is particularly burdensome for surrogate decision-makers, who must make choices on behalf of their incapacitated family members. The Conceptual Taxonomy of Uncertainty is one model through which physician and surrogate communication can be analyzed to identify strategies for reducing uncertainty in surrogate decision-making. Our objective was to examine themes of uncertainty in physician communication of prognosis and surrogate goals-of-care decision-making for critically ill patients with traumatic brain injury (TBI). ⋯ We found that physician communication strategies rarely addressed surrogate needs regarding uncertainty adequately, suggesting an urgent need for future research into improved communication of prognostic uncertainty.

Inactivated Four-Factor Prothrombin Complex Concentrate Dosing Practices for Reversal of Warfarin-Related Intracranial Hemorrhage.
Inactivated four-factor prothrombin complex concentrate (I4F-PCC, Kcentra®) has become an important agent for the urgent or emergent reversal of bleeding associated with vitamin K antagonists such as warfarin. There is recognized inter-institutional variability with the use of I4F-PCC, especially as it relates to dosing practices. We sought to characterize variations in I4F-PCC dosing practices and their impact on patient outcomes and describe overall real-world clinical practice surrounding I4F-PCC utilization in the context of the management of warfarin-related intracranial hemorrhage (ICH). ⋯ Most patients received single doses of I4F-PCC, with adjunctive reversal agents and rounding doses to vial size. The time difference from baseline INR to factor product administration is a potential opportunity for process improvement in the management of warfarin-related ICH.

Systemic Severity and Organ Dysfunction in Subarachnoid Hemorrhage: A Large Retrospective Multicenter Cohort Study.
Acute physiologic derangements and multiple organ dysfunction are common after subarachnoid hemorrhage. We aimed to evaluate the simplified acute physiology score 3 (SAPS-3) and the sequential organ failure assessment (SOFA) scores for the prediction of in-hospital mortality in a large multicenter cohort of SAH patients. ⋯ nSAPS-3 and nSOFA scores were independently associated with in-hospital mortality after SAH. The addition of these scores improved early prediction of hospital mortality in our cohort and should be integrated to other specific prognostic indices in the early assessment of SAH.
