From Days to Minutes: An Autonomous AI Agent Achieves Reliable Clinical Triage in Remote Patient Monitoring
This study introduces Sentinel, an autonomous AI agent designed to revolutionize remote patient monitoring (RPM) by providing reliable, contextual clinical triage of vital signs. By overcoming the limitations of traditional rule-based systems and human-intensive approaches, Sentinel offers a scalable solution to improve patient safety and operational efficiency in healthcare.

Agent Reliability and Inter-rater Consistency
Sentinel demonstrates almost perfect self-consistency (Fleiss' κ = 0.850) with 83% perfect 5/5 agreement across multiple runs, significantly exceeding human intra-rater reliability (averaged 75.8%). Agent-reviewer agreement (62.1%) falls within the range of inter-human agreement (59.7%), indicating alignment with professional consensus while reducing extreme subjectivity seen among clinicians.
Outperforming Traditional Rule-Based Systems
Unlike conventional RPM alerting, Sentinel avoids both data floods and missed cases. The fixed threshold baseline flagged 53.5% of readings as urgent (high alert burden) with only 59.2% specificity. The adaptive baseline, by normalizing chronic abnormalities, missed 81.7% of clinician-identified actionable cases. Sentinel achieved 69.4% four-level accuracy, 88.5% actionable sensitivity, and 85.7% specificity, offering a superior balance.
Superiority in Patient Safety Metrics
Leave-one-out analysis revealed Sentinel outperformed every individual clinician in patient safety, detecting 97.5% of emergencies (vs. clinician aggregate 60.0%) and 90.9% of actionable cases (vs. clinician aggregate 69.5%). The agent's exact match rate (75.5%) was comparable to most clinicians, and its overtriage rate (18.9%) was lower than two of the six clinicians, demonstrating a safer operating profile without excessive false positives.
Clinically Defensible Escalations
Agent-human disagreements skewed toward overtriage (22.5% vs. 8.1% undertriage), reflecting a deliberate tilt towards clinical caution. Independent physician adjudication of severe overtriage cases (agent-majority gap ≥2 levels) found that 88–94% of these escalations were clinically justified or debatable, with 0% true overtriage after consensus. This confirms Sentinel's ability to identify real concerns overlooked by human majorities.
Cost-Effective and Scalable Operations
Sentinel processes each triage at a median cost of $0.34 and a median duration of 94.5 seconds. This cost-efficiency allows organizations to provide intensive, contextualized monitoring at a fraction of the cost of human clinical review, making the TIM-HF2 model (which reduced mortality by 30%) economically scalable across large patient populations. The agent allocates more reasoning effort to higher-acuity cases, ensuring appropriate diligence.

Case Study: Agent Detects Missed Emergency (Case D from Paper)
Patient: 82F, HFpEF, CKD Stage 3b-4, Severe COPD on supplemental O2, recent hospitalization. Vital sign reading: BP 172/117, HR 59.
Human Majority: MONITOR
Agent Classification: EMERGENCY
Agent Reasoning: The agent identified a convergence of alarming findings: marked diastolic hypertension of 117 mmHg (a +36 mmHg surge, threatening AKI in CKD patient); acute relative bradycardia (HR 59, a 52 bpm drop from recent, indicating conduction disease or medication effect during unreconciled period); ominous hemodynamic pattern (severe hypertension with acute relative bradycardia); and absent clinical oversight for 6 days despite prior concerns.
Adjudication: Both independent physician reviewers agreed with Emergency, confirming the clinical validity of the agent's escalation. This case highlights the agent's ability to synthesize full patient context and apply tie-breaker rules (if immediate safety risk is uncertain but possible, choose EMERGENCY) to prevent missed critical deteriorations that human reviewers, even with pre-assembled summaries, classified as less severe.
Impact: The agent's deep contextual reasoning identified a life-threatening situation where human clinicians, reviewing the same pre-assembled data summary, initially categorized it as 'Monitor'. This demonstrates Sentinel's capability to act as a crucial safety net, particularly for complex patients with multiple comorbidities.
