Abstract
BACKGROUND: Spontaneous bacterial peritonitis (SBP)-associated septic shock carries significant mortality in cirrhosis. AIM: To determine whether practice-related aspects of antimicrobial therapy contribute to high mortality. METHODS: Retrospective cohort study of all (n = 126) cirrhotics with spontaneous bacterial peritonitis (neutrophil count >250 or positive ascitic culture)-associated septic shock (1996-2011) from an international, multicenter database. Appropriate antimicrobial therapy implied either in vitro activity against a subsequently isolated pathogen (culture positive) or empiric management consistent with broadly accepted norms (culture negative). RESULTS: Overall hospital mortality was 81.8%. Comparing survivors (n = 23) with non-survivors (n = 103), survivors had lower Acute Physiology and Chronic Health Evaluation (APACHEII) (mean ± s.d.; 22 ± 7 vs. 32 ± 8) and model for end-stage liver disease (MELD) (24 ± 9 vs. 34 ± 11) scores and serum lactate on admission (4.9 ± 3.1 vs. 8.9 ± 5.3), P < 0.001 for all. Survivors were less likely to receive inappropriate initial antimicrobial therapy (0% vs. 25%, P = 0.013) and received appropriate antimicrobial therapy earlier [median 1.8 (1.1-5.2) vs. 9.5 (3.9-14.3) h, P < 0.001]. After adjusting for covariates, APACHEII [OR, odds ratio 1.45 (1.04-2.02) per 1 unit increment, P = 0.03], lactate [OR 2.34 (1.04-5.29) per unit increment, P = 0.04] and time delay to appropriate antimicrobials [OR 1.86 (1.10-3.14) per hour increment, P = 0.02] were significantly associated with increased mortality. CONCLUSIONS: Cirrhotic patients with septic shock secondary to spontaneous bacterial peritonitis have high mortality (>80%). Each hour of delay in appropriate antimicrobial therapy was associated with a 1.86 times increased hospital mortality. Admission APACHEII and serum lactate also significantly impacted hospital mortality. Earlier initiation of appropriate antimicrobial therapy could substantially improve outcome.

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
