Abstract
Background: Early observation of clinical worsening is critical for reducing morbidity and mortality in hospitalized patients. Conventional early warning scores have limited accuracy, while artificial intelligence–powered early warning systems (AI-EWS) may offer improved predictive value. Objectives: To estimate the influence of AI-EWS on case results, involving mortality, intensive care unit (ICU) transfer, and duration of hospitalization. Methods: This systematic review and meta-analysis have been done after PRISMA guidelines. Five investigations (2013–2024) involving 95,162 patients were included. Eligible studies compared AI-EWS with standard care or conventional scoring systems and reported mortality, ICU transfer, or length of stay. Data extraction was performed independently by 2 reviewers. Risk of bias has been evaluated utilizing the Cochrane instrument for randomized trials and the Newcastle–Ottawa Scale for observational studies. Random-influences models have been utilized for pooled analysis. Results: AI-EWS significantly reduced all-cause mortality (OR = 0.76; ninety-five percent confidence interval: 0.63–0.91; p equal to 0.004). An insignificant variance has been found for ICU transfers (OR = 0.90; ninety-five percent confidence interval: 0.76–1.07; p equal to 0.22). Duration of stay in the hospital was modestly reduced in AI-EWS groups (MD = –0.35 days; ninety-five percent confidence interval: –0.68 to –0.01; p = 0.04). Risk of bias was low to moderate, mainly due to heterogeneity in study design. Conclusion: AI-EWS are associated with lower mortality and shorter hospital stays compared with conventional systems, though their effect on ICU transfers remains uncertain. Larger high-quality trials are required to confirm these findings.

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
