Derivation and Validation of Two Decision Instruments for Selective Chest CT in Blunt Trauma: A Multicenter Prospective Observational Study (NEXUS Chest CT).
Unnecessary diagnostic imaging leads to higher costs, longer emergency department stays, and increased patient exposure to ionizing radiation. We sought to prospectively derive and validate two decision instruments (DIs) for selective chest computed tomography (CT) in adult blunt trauma patients. ⋯ We prospectively derived and validated two DIs (Chest CT-All and Chest CT-Major) that identify blunt trauma patients with clinically significant thoracic injuries with high sensitivity, allowing for a safe reduction of approximately 25%-37% of unnecessary chest CTs. Trauma evaluation protocols that incorporate these DIs may decrease unnecessary costs and radiation exposure in the disproportionately young trauma population.

Multicenter StudyVentilator-Associated Events: Prevalence, Outcome, and Relationship With Ventilator-Associated Pneumonia.
Centers for Disease Control and Prevention built up new surveillance paradigms for the patients on mechanical ventilation and the ventilator-associated events, comprising ventilator-associated conditions and infection-related ventilator-associated complications. We assess 1) the current epidemiology of ventilator-associated event, 2) the relationship between ventilator-associated event and ventilator-associated pneumonia, and 3) the impact of ventilator-associated event on antimicrobials consumption and mechanical ventilation duration. ⋯ Ventilator-associated event is very common in a population at risk and more importantly highly related to antimicrobial consumption and may serve as surrogate quality indicator for improvement programs.

Inter-rater Reliability and Diagnostic Performance of Subjective Evaluation of Sublingual Microcirculation Images by Physicians and Nurses: A Multicenter Observational Study.
This was a cross-sectional multicenter study to investigate the ability of physicians and nurses from three different countries to subjectively evaluate sublingual microcirculation images and thereby discriminate normal from abnormal sublingual microcirculation based on flow and density abnormalities. ⋯ The subjective evaluations of sublingual microcirculation by physicians and nurses agreed well with a conventional offline analysis and were highly sensitive and specific for sublingual microcirculatory abnormalities.
