Abstract
PURPOSE: We describe the development and implementation of a comprehensive multidisciplinary vascular access (VA) program and describe its impact on VA distribution rates. METHODS: A retrospective review of all incident and prevalent patients in our hemodialysis (HD) unit was conducted in September 2001 to determine baseline data including: type of VA along with patient characteristics and comorbidities. Similar data was extracted from the database in 2005 for incident and prevalent patients. RESULTS: The VA program had a significant impact on arteriovenous fistulae (AVF) rates in both incident and prevalent HD patients: incident AVF rates increased from 14 to 39% (p=0.04) and prevalent AVF rates from 60 to 64% (p=0.015). Multivariate analysis revealed that male gender (OR 1.79 [CI 0.85-0.98, p=0.006]) and year of dialysis initiation 2005 vs. 2001 (OR 1.65 [CI 1.09-2.5, p=0.017]) were associated with AVF use among prevalent HD patients. Furthermore, age (per 5 years over 70) is associated with a decreased likelihood of having an AVF (OR 0.91 [CI 0.85-0.98, p=0.009]) whereas comorbidities of cardiovascular disease and diabetes had no impact. CONCLUSION: We demonstrate that a structured VA program can increase the number of functioning fistulas without a corresponding increase in catheters in incident and prevalent HD patients.

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 it
