Four year surveillance of central line-associated bloodstream infection (CLABSI) in neonatal intensive care unit (NICU)
Bibliographic record
Abstract
All laboratory confirmed blood cultures from the NICU were evaluated to determine CLABSI using the National Healthcare Safety Network (NHSN) definition prior and after 2008.The PICC team are specific bedside nurses trained to insert, monitor insertion site and line removal. They use age/weight specific skin antiseptics (2% CHG, 0.5% and 2% CHG in 70% alcohol) with designated equipment. Bedside nurses access infusion lines for administering medication, total parenteral nutrition and changing the line/connectors. Over the past 4 years (2007–11) there were 37 CLABSI using the old NHSN definition versus 22 CLABSI with the new definition. The infection rate was 5.97 /1000 Catheter Days (CD) and 3.55/1000 CD respectively. The overall catheter utilization ratio was 0.20.The most prevalent microorganisms recovered were Coagulase-negative Staphylococci (71%) followed by Candida , Enterobacter and Klebsiella species (6% each).There were two associated CLABSI mortalities within 30 days. Rates of CLABSI decreased from 8.1 to 3.71 using old definition and from 4.7 to 1.06 per 1000 CD using new definition 2007-08 to 2010-11.Catheter utilization ratio increased from 0.19 to 0.24. Implementation of a dedicated interprofessional PICC Team and a prevention bundle was successful in decreasing rates of CLABSI in the NICU. The change in definition considerably affects the rates of CLABSI (-41%).

How this classification was reachedexpand
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, unvalidatedMachine predicted; a candidate call from one teacher head, not a consensus.
