AI-Powered Early Warning System Halves Cardiac Arrest Risk in General Wards
A prospective, non-randomized trial reveals that an AI-based cardiac arrest prediction model (AI-SaMD) significantly reduces in-hospital cardiac arrest and all-cause mortality among general ward patients. Integrated seamlessly into clinical workflows, this system requires no additional resources while enhancing patient safety and optimizing rapid response system performance.

AI-SaMD: Revolutionizing Cardiac Arrest Prediction
This study investigates the clinical effectiveness of VUNO Med®-DeepCARSTM (AI-SaMD), an AI-based cardiac arrest prediction model, in general ward patients. Operating as a software as a medical device (AI-SaMD), it generates real-time risk scores from vital signs, alerting clinical staff to elevated in-hospital cardiac arrest (IHCA) risk within 24 hours.
The trial aimed to assess if AI-SaMD-guided interventions could improve patient outcomes without modifying existing staffing or protocols, addressing previous studies' limitations where outcomes were confounded by significant RRS efferent limb restructuring.
Study Design & AI-SaMD Integration
This 1-year, prospective, non-randomized, single-blinded interventional trial was conducted at a tertiary academic hospital. Adult general ward admissions (excluding DNR or missing vital signs) were screened.
Patients were categorized into a "target cohort" (AI-SaMD alert triggered, score ≥ 95) and a "non-target cohort." Within the target cohort, patients were further divided into "AI-SaMD-guided" (intervention/reassessment within 24h of first alert) and "usual care" (no action within 24h) groups.
AI-SaMD was embedded in the EMR, displaying alerts alongside conventional EWSs. RRS teams provided guidance for reassessment and interventions, but no mandatory protocols or additional resources were introduced. Primary outcome: ward-based cardiac arrest. Secondary outcome: in-hospital mortality.

Significant Reduction in Adverse Clinical Events
The study included 35,627 general ward admissions. Among the 2906 patients triggering an AI-SaMD alert (target cohort), 1409 received AI-SaMD-guided interventions.

Strategic Advantages for Enterprise Healthcare
This study provides strong evidence for the clinical effectiveness of AI-SaMD in reducing adverse events in general ward patients. The findings demonstrate that earlier and proactive responses following AI-SaMD alerts are crucial for improved patient outcomes, with delays of 20-24 hours leading to significantly higher adverse event rates.
The ability of AI-SaMD to enhance patient monitoring and risk stratification without disrupting established workflows or demanding extra resources makes it highly applicable for healthcare systems facing workforce shortages.
The study's robust methodology, including multiple sensitivity analyses, reinforces confidence in these findings. Future research will focus on assessing the combined effect of AI-SaMD alerts and RRS efferent limb function through randomized controlled trials.
Impact of Timely Intervention and Continuous Compliance
The study highlighted the critical role of timely responses to AI-SaMD alerts. Delays in intervention were directly linked to worse outcomes. Specifically, interventions delayed by 20–24 hours resulted in a 10 times higher incidence of adverse outcomes compared to interventions initiated within 4 hours. Furthermore, high compliance rates with all continuous AI-SaMD alerts (exceeding 90%) were associated with a 2–4-fold lower incidence of adverse outcomes, underscoring the importance of ongoing monitoring and response. This demonstrates that continuous vigilance, guided by AI, significantly enhances patient safety and outcomes in the general ward.
