The aim of this study was to describe the utilization patterns of brain tissue oxygen (PbtO2) monitoring following severe traumatic brain injury (TBI) and determine associations with mortality, health care use, and pulmonary toxicity. ⋯ PbtO2 monitor utilization varied widely throughout the study period by calendar year and hospital. PbtO2 monitoring in addition to ICP monitoring, compared with ICP monitoring alone, was associated with a decreased in-hospital mortality, a longer length of stay, and a similar risk of ARDS. These findings provide further guidance for clinicians caring for patients with severe TBI while awaiting completion of further randomized controlled trials.

Observational Study
Hierarchical Cluster Analysis Identifies Distinct Physiological States After Acute Brain Injury.
Analysis of intracranial multimodality monitoring data is challenging, and quantitative methods may help identify unique physiological signatures that inform therapeutic strategies and outcome prediction. The aim of this study was to test the hypothesis that data-driven approaches can identify distinct physiological states from intracranial multimodality monitoring data. ⋯ A data-driven approach can identify distinct groupings from invasive multimodality neuromonitoring data that may have implications for therapeutic strategies and outcome predictions. These groupings could be used as classifiers to train machine learning models that can aid in the treatment of patients with acute brain injury. Further work is needed to replicate the findings of this exploratory study in larger data sets.

We evaluated the association between D-dimer (DD) levels and long-term neurological prognoses among patients with isolated traumatic brain injury. ⋯ We revealed an association between DD levels and poor long-term neurological outcomes among patients with isolated traumatic brain injury.
