Abstract

fetched live from OpenAlex

Individuals who require renal replacement therapy overwhelmingly choose outpatient hemodialysis. Appropriate cannulation techniques are an essential element in access preservation and in the prevention of access-related complications. Missed cannulations can result in damage of arteriovenous fistulas (AVFs) and arteriovenous grafts (AVGs). Ultrasound-guided cannulation is an effective technique for the placement of peripheral intravenous (IV) catheters and central venous catheters (CVCs) for hemodialysis. The purposes of this project were to determine if ultrasound-guided cannulation of AVFs decreased the number of missed cannulations, to determine staff and patient perceptions regarding cannulation, and to implement a quality incentive program (QIP) to implement an evidence-based ultrasound-guided policy and procedure, training program, and competency evaluation at a hospital-based dialysis facility.

Fetched live from OpenAlex and de-inverted. Abstracts are not stored in this database: the inverted indexes are 8.6 GB of the frame’s 9.3 GB of text, and the host has 13 GB free.

Not 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.
