Abstract
BACKGROUND: Most deaths in patients with abdominal vascular injuries (ABVI) are caused by exsanguination and irreversible shock. Therefore, time to definitive hemorrhage control is an important factor affecting survival. The study goals were: (1) document current outcomes in patients with ABVI, and (2) compare outcomes to those from the era preceding improvements in an urban prehospital system. METHODS: A retrospective review of all patients with ABVI at an urban level 1 trauma center was completed. Patients injured prior to prehospital transport improvements (1991-1994) were compared to those following a reduction in transport times (1995-2004). RESULTS: Of 388 patients, 70 (18%) arrived prior to prehospital improvements (1991-1994). Patient/injury demographics were similar in both groups (age, sex, penetrating mechanism; p > 0.05). The number of patients presenting with ABVI increased (23 vs. 35 per year; p < 0.05) concurrent to a reduction in transport times (27 vs. 20 minutes; p < 0.05). Patients were more frequently unstable (63% vs. 91%; p < 0.05). Regardless of the specific vessel, mortality increased (37% vs. 67%; p < 0.05) following prehospital improvements. CONCLUSIONS: A reduction in urban transport times resulted in an increase in (1) the number of patients arriving with abdominal vascular injuries, (2) the proportion presenting in physiologic extremis, and (3) overall mortality.

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
