Multicenter StudyShort-course aminoglycosides as adjunctive empirical therapy in patients with Gram-negative bloodstream infection, a cohort study.
Short-course aminoglycosides as adjunctive empirical therapy to β-lactams in patients with a clinical suspicion of sepsis are used to broaden antibiotic susceptibility coverage and to enhance bacterial killing. We quantified the impact of this approach on 30-day mortality in a subset of sepsis patients with a Gram-negative bloodstream infection. ⋯ Short-course adjunctive aminoglycoside treatment as part of empirical therapy with β-lactam antibiotics in patients with GN-BSI did not result in improved outcomes, despite better antibiotic coverage of pathogens.

We report the utilisation and impact of a novel triage-based electronic screening tool (eST) combined with clinical assessment to recognise sepsis in paediatric ED. ⋯ Utilisation of a novel triage-based eST allowed sepsis screening in over 99% of eligible patients. The screening tool showed good accuracy to recognise sepsis at triage in the ED, which was augmented further by combining it with clinician assessment. The screening tool requires further refinement through multicentre evaluation to avoid missing sepsis cases.

Randomized Controlled Trial Multicenter StudyProcalcitonin to Reduce Long-Term Infection-associated Adverse Events in Sepsis: A Randomized Trial.
Rationale: Although early antimicrobial discontinuation guided by procalcitonin (PCT) has shown decreased antibiotic consumption in lower respiratory tract infections, the outcomes in long-term sepsis sequelae remain unclear. Objectives: To investigate if PCT guidance may reduce the incidence of long-term infection-associated adverse events in sepsis. Methods: In this multicenter trial, 266 patients with sepsis (by Sepsis-3 definitions) with lower respiratory tract infections, acute pyelonephritis, or primary bloodstream infection were randomized (1:1) to receive either PCT-guided discontinuation of antimicrobials or standard of care. ⋯ The cost of hospitalization was also reduced in the PCT arm. Conclusions: In sepsis, PCT guidance was effective in reducing infection-associated adverse events, 28-day mortality, and cost of hospitalization. Clinical trial registered with www.clinicaltrials.gov (NCT03333304).

Multicenter Study
Machine learning predicts mortality in septic patients using only routinely available ABG variables: a multi-centre evaluation.
To evaluate the application of machine learning methods, specifically Deep Neural Networks (DNN) models for intensive care (ICU) mortality prediction. The aim was to predict mortality within 96 hours after admission to mirror the clinical situation of patient evaluation after an ICU trial, which consists of 24-48 hours of ICU treatment and then "re-triage". The input variables were deliberately restricted to ABG values to maximise real-world practicability. ⋯ An LSTM-based model could help physicians with the "re-triage" and the decision to restrict treatment in patients with a poor prognosis.

Multicenter StudyThe Diagnostic Yield of Routine Admission Blood Cultures in Critically Ill Patients.
Although the Surviving Sepsis Campaign bundle recommends obtaining blood cultures within 1 hour of sepsis recognition, adherence is suboptimal in many settings. We, therefore, implemented routine blood culture collection for all nonelective ICU admissions (regardless of infection suspicion) and evaluated its diagnostic yield. ⋯ Implementation of routine blood cultures was associated with a 1.5-fold increase of detected bloodstream infection. The 4.3-fold increase in contaminated blood cultures was not associated with an increase in vancomycin use in the ICU.
