Tunnelled central venous catheter-related bloodstream infection in Canadian blood stem cell transplant recipients: Associated costs
Bibliographic record
Abstract
Problem: Central catheter-related bloodstream infection (CRBSI) is associated with increased health care costs and patient morbidity.The purpose of the study was to estimate the direct inpatient charges of CRBSI in Canadian blood and marrow cell transplant recipients with a tunnelled central venous catheter (CVC).Method: A case-controlled comparison of patient records from a single centre was completed.Records indicating CRBSI were paired for comparison to patient records not indicating CRBSI in the following domains: length of stay, laboratory tests, diagnostic tests, medications used, consultations to a specialty physician, catheter replacement costs, and length of stay in the intensive care unit.Results: Cases stayed on average an extra 19.37 days in the hospital.Extra charges for diagnosing and treating CRBSI averaged $4,739.95.The total estimated burden of CRBSI in Canadian blood and marrow transplant for the 2013 fi scal year was $44,816.48 per incident.Infections also reduced the length of catheter use time by an average of 18.68 days.

Full frame machine prediction
Teacher imitationNot calibrated prevalence, not ground truth. Human validation pending. The Gemma side is a direct model label for every work in the frame, read from the title-only record. The Codex side is a classifier learned from the 10,348 direct Codex labels and calibrated to design-weighted sample rates; fields without enough sample support carry no Codex call. Candidate is the union of the two sides; consensus is their intersection. These outputs are machine_predicted_unvalidated and are not human 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 source (direct Gemma or distilled Codex), not a consensus.
