Multicenter StudyStatins and Delirium During Critical Illness: A Multicenter, Prospective Cohort Study.
Since statins have pleiotropic effects on inflammation and coagulation that may interrupt delirium pathogenesis, we tested the hypotheses that statin exposure is associated with reduced delirium during critical illness, whereas discontinuation of statin therapy is associated with increased delirium. ⋯ In critically ill patients, ICU statin use was associated with reduced delirium, especially early during sepsis; discontinuation of a previously used statin was associated with increased delirium.

Multicenter StudyCompliance with prevention practices and their association with central line-associated bloodstream infections in neonatal intensive care units.
Bundles and checklists have been shown to decrease the rates of central line-associated bloodstream infections (CLABSIs), but implementation of these practices and association with CLABSI rates have not been described nationally. We describe implementation and levels of compliance with preventive practices in a sample of US neonatal intensive care units (NICUs) and assess their association with CLABSI rates. ⋯ Most of the NICUs in this national sample have instituted CLABSI prevention policies and monitor compliance, although reporting compliance ≥95% was suboptimal. Reporting ≥95% compliance with select CLABSI prevention practices was associated with lower CLABSI rates. Future studies should focus on identifying and improving compliance with effective CLABSI prevention practices in neonates.

Multicenter Study Observational Study
Age-related differences in biomarkers of acute inflammation during hospitalization for sepsis.
The authors aimed to evaluate age-related differences in inflammation biomarkers during the first 72 h of hospitalization for sepsis. This was a secondary analysis of a prospective observational cohort of adult patients (n = 855) from 10 urban academic emergency departments with confirmed infection and two or more systemic inflammatory response syndrome criteria. Six inflammation-related biomarkers were analyzed-chemokine (CC-motif) ligand-23, C-reactive protein, interleukin-1 receptor antagonist, neutrophil gelatinase-associated lipocalin (NGAL), peptidoglycan recognition protein, and tumor necrosis factor receptor-1a (TNFR-1a)-measured at presentation and 3, 6, 12, 24, 48, or 72 h later. ⋯ However, older adults had higher mean values during the entire 72-h period only for NGAL and TNFR-1a and higher final 72-h values only for TNFR-1a. Adjustment or stratification by sepsis severity did not change the age-inflammation associations. Although older adults had higher levels of inflammation at presentation and an increased incidence of severe sepsis and septic shock, these age-related differences in inflammation largely resolved during the first 72 h of hospitalization.

Multicenter Study Comparative StudyGuideline Bundles Adherence and Mortality in Severe Sepsis and Septic Shock.
Surviving Sepsis Campaign bundles have been associated with reduced mortality in severe sepsis and septic shock patients. Case-mix adjusted mortality evaluations have not been performed to compare hospitals participating in sepsis bundle programs with those not participating. We aimed to achieve an individual bundle target adherence more than 80% and a relative mortality reduction of at least 15% (absolute mortality reduction 5.2%) at the end of 2012. ⋯ Implementation of a national sepsis program resulted in improved adherence to sepsis bundles in severe sepsis and septic shock patients and was associated with reduced adjusted in-hospital mortality only in participating ICUs, suggesting direct impact of sepsis screening and bundle application on in-hospital mortality.

Accuracy of oxygen tissue saturation values in assessing severity in patients with sepsis admitted to emergency departments.
Near-infrared spectrometry assesses hemoglobin saturation of oxygen in tissues (StO2). Although it may provide additional information on local microcirculation function, the usefulness of near-infrared spectrometry in septic patients is debated. This study evaluated whether baseline StO2 value is useful in septic patients admitted to the emergency department with a diagnosis of severe sepsis. ⋯ This study fails to show any value of StO2 baseline at triage for early detection of severe sepsis in emergency patients.
