The rapid influx of patients in emergency departments (EDs) necessitates advanced systems for triage prioritization, where artificial intelligence (AI) can orchestrate decision-making to enhance efficiency and equity. This conceptual manuscript proposes a novel AI-orchestrated triage intelligence architecture designed to integrate heterogeneous data streams, clinical workflows, and governance mechanisms within ED settings. Drawing from peer-reviewed literature on clinical AI architectures, healthcare analytics infrastructures, and decision support pipelines, we synthesize theoretical foundations to outline a layered orchestration topology that addresses interoperability challenges, real-time intelligence processing, and ethical monitoring. The proposed framework, termed the emergency triage orchestration lattice (ETOL), features modular layers for data ingestion, predictive analytics, orchestration governance, and feedback integration, ensuring adaptive triage without empirical validation. Conceptual formulas capture decision confidence aggregation and governance load distribution, highlighting theoretical trade-offs in latency and resource allocation. By emphasizing infrastructural resilience and human-AI symbiosis, this architecture theorizes improved triage throughput and reduced bias propagation in high-acuity environments. Implications for ED workflow redesign and AI deployment scalability are discussed, underscoring the need for robust interoperability frameworks to support future intelligence ecosystems. This work contributes to the discourse on AI governance in acute care, advocating for orchestrated systems that prioritize clinical relevance over isolated algorithmic performance.

This article proposes a conceptual framework for a diagnostic support system in emergency departments that leverages large language models, retrieval-augmented generation, and chain-of-thought reasoning. By combining triage notes and vital signs, the system generates a ranked differential diagnosis list to assist clinicians without replacing their judgment. The framework includes components like a triage note encoder, a vital sign encoder, a retrieval module, and a diagnosis ranker, using evidence from clinical guidelines, curated references, and de-identified prior cases. The approach grounds the model in authoritative knowledge while ensuring transparency and explainability in the diagnostic process. However, prospective validation, integration into workflows, and clinician oversight are crucial before implementation to ensure safety and effectiveness.
