Procalcitonin-guided decision-making results in a significant reduction of antibiotic therapy and hospital stay in neonates with suspected early-onset sepsis
Bibliographic record
Abstract
Commentary on : Stocker M, van Herk W, El Helou S, et al . Procalcitonin-guided decision making for duration of antibiotic therapy in neonates with suspected early-onset sepsis: a multicentre, randomised controlled trial (NeoPIns). Lancet 2017;390:871–81. The diagnostic approach of sepsis in neonates is challenging with lack of sensitive and specific microbiological tests leading ultimately to antibiotic overuse in this population. Host-derived blood markers of infection are promising tools to better guide antibiotic management. In adults, use of procalcitonin (PCT) has shown to reduce antibiotic usage with positive effects on clinical outcome.1 The study by Stocker et al assessed whether the concept of PCT-guided antibiotic management would also work in neonates.2 This is a multicentre, randomised controlled trial that prospectively included neonates with suspected early-onset sepsis in 18 different Hospitals in the Netherlands, Switzerland, Canada and Czech Republic. Probability of sepsis was assessed by scoring system based on risk factors, clinical symptoms and conventional laboratory tests. Neonates were …

Direct model labels (unvalidated)
Per-model category and study-design labels from the labeling rounds. They are machine output, unvalidated, and the disagreement between models ships as data. No study design here is MEDLINE-validated yet.

Full frame distilled prediction
Teacher imitationNot calibrated prevalence, not ground truth. Human validation pending. Learned from the 10,348 direct Codex labels and 10,348 direct Gemma labels. Candidate is the union of thresholded teacher heads; consensus is their intersection. These outputs are machine_predicted_unvalidated and are not human labels or direct frontier model labels.

Machine scores (provisional)
The two teacher heads of the student model, read on this work. A score orders the frame for review; it never asserts a category, and the validation status ships verbatim with every row.
Baseline scores from an immature model (maturity gate not passed, 7 training rounds). Scores rank; they never assert a category.
score_only:v0-immature-baseline · verbatim from the scoring run: score_only means the number may rank works, and no category label ships from itClassification
machine, unvalidatedLabeled directly by 2 models reading the full record.
