CONTEXT In previous smaller trials, a procalcitonin (PCT) algorithm reduced antibiotic use in patients with lower respiratory tract infections (LRTIs). OBJECTIVE To examine whether a PCT algorithm can reduce antibiotic exposure without increasing the risk for serious adverse outcomes. DESIGN, SETTING, AND PATIENTS A multicenter, noninferiority,(More)
BACKGROUND Acute respiratory tract infections (ARTI) are among the most frequent reasons for consultations in primary care. Although predominantly viral in origin, ARTI often lead to the prescription of antibiotics for ambulatory patients, mainly because it is difficult to distinguish between viral and bacterial infections. Unnecessary antibiotic use,(More)
BACKGROUND In controlled studies, procalcitonin (PCT) has safely and effectively reduced antibiotic drug use for lower respiratory tract infections (LRTIs). However, controlled trial data may not reflect real life. METHODS We performed an observational quality surveillance in 14 centers in Switzerland, France, and the United States. Consecutive adults(More)
INTRODUCTION Close monitoring and repeated risk assessment of sepsis patients in the intensive care unit (ICU) is important for decisions regarding care intensification or early discharge to the ward. We studied whether considering plasma kinetics of procalcitonin, a biomarker of systemic bacterial infection, over the first 72 critical care hours improved(More)
Previous randomized controlled trials suggest that using clinical algorithms based on procalcitonin levels, a marker of bacterial infections, results in reduced antibiotic use without a deleterious effect on clinical outcomes. However, algorithms differed among trials and were embedded primarily within the European health care setting. Herein, we summarize(More)
INTRODUCTION Previous reports suggest that endothelial activation is an important process in sepsis pathogenesis. We investigated the association between biomarkers of endothelial cell activation and sepsis severity, organ dysfunction sequential organ failure assessment (SOFA) score, and death. METHODS This is a prospective, observational study including(More)
RATIONALE High cortisol levels are of prognostic value in sepsis. The predictive value of cortisol in pneumonia is unknown. Routinely available assays measure serum total cortisol (TC) and not free cortisol (FC). Whether FC concentrations better reflect outcome is uncertain. OBJECTIVES To investigate the predictive value of TC and FC in community-acquired(More)
Procalcitonin is a surrogate biomarker for estimating the likelihood of a bacterial infection. Procalcitonin-guided initiation and termination of antibiotic therapy is a novel approach utilized to reduce antibiotic overuse. This is essential to decrease the risk of side effects and emerging bacterial multiresistance. Interpretation of procalcitonin levels(More)
OBJECTIVE In an effort to improve upon the traditional sepsis syndrome definitions, the predisposition, infection, response, organ dysfunction (PIRO) model was proposed to better characterize sepsis. The objective of this investigation was to derive and validate a sepsis staging system based on the PIRO concept that risk stratifies patients with suspected(More)
Identifying strongly connected substructures in large networks provides insight into their coarse-grained organization. Several approaches based on the optimization of a quality function, e.g., the modularity, have been proposed. We present here a multistep extension of the greedy algorithm MSG that allows the merging of more than one pair of communities at(More)
