Hospital environments face escalating demands for proactive, multimodal risk management amid rising patient complexity and data volume. While neural-enabled artificial intelligence has advanced specialized clinical decision support, existing systems remain fragmented, lacking unified coordination across electronic health record ecosystems, predictive modules, and governance mechanisms. This conceptual systems article introduces the neural-enabled risk orchestration (NERO) framework. This novel architectural model orchestrates multiple neural intelligence components into a cohesive topology for hospital-wide risk mitigation. Grounded exclusively in theoretical, infrastructural, and architectural principles, NERO comprises five interdependent layers—multimodal neural perception, risk propagation and connectivity, central orchestration engine, adaptive synthesis and prioritization, and governance feedback with drift mitigation—linked through bidirectional temporal feedback loops. The model addresses core gaps in current clinical AI architectures by enabling dynamic weighting of risk signals, context-aware decision synthesis, and continuous recalibration without empirical performance claims. Theoretical integration with interoperability standards and workflow models ensures seamless integration into hospital operations, while robust governance manages neural drift and compliance. By synthesizing advances in clinical decision support pipelines, EHR intelligence ecosystems, and AI monitoring systems, NERO offers a foundational blueprint for scalable, human-centric neural-enabled risk platforms. This orchestration-centric approach theoretically reduces decision latency trade-offs and enhances adaptive risk intelligence across acute and critical care settings.

The integration of artificial intelligence (AI) into healthcare systems marked a pivotal evolution in clinical analytics architectures and governance structures, transforming data-driven decision-making from siloed, retrospective analyses to dynamic, predictive, and integrated frameworks. This period witnessed rapid advancements in machine learning (ML) applications for healthcare infrastructure, encompassing electronic health records (EHRs), imaging diagnostics, population health management, and real-time monitoring systems. Key developments included the shift toward federated learning to address data privacy concerns, the emergence of explainable AI (XAI) to enhance clinical trustworthiness, and the standardization of regulatory pathways for AI as medical devices. Architecturally, healthcare systems evolved from static analytics pipelines—where data ingestion, model training, and inference occurred in isolated phases—to adaptive, closed-loop configurations that incorporate feedback mechanisms for continuous model refinement and human-AI collaboration. Governance structures are adapted accordingly, emphasizing ethical frameworks to mitigate bias, ensure data equity, and promote algorithmic accountability, particularly for underserved populations.

Sepsis remains a major cause of mortality in intensive care units, largely due to delayed recognition and the limitations of current machine learning models that rely on retrospective, static electronic health record data. Although these models often show strong offline performance, their clinical translation is constrained by mismatches between training conditions and real-time bedside environments. Most existing systems depend on hourly aggregates or batch processing, introducing delays that reduce their usefulness within the narrow therapeutic window for intervention. In contrast, continuous vital sign streams generated by modern bedside monitors represent an underused source of real-time physiological information. This perspective argues that effective sepsis prediction requires a shift toward edge AI architectures that enable low-latency, privacy-preserving inference directly at the point of care. By treating physiological signals as continuous data streams rather than static records, and by deploying computation at the bedside instead of centralized cloud systems, models can better align with clinical realities. Such an approach could improve early detection, reduce alert fatigue through more context-aware predictions, and mitigate privacy, latency, and bandwidth challenges associated with cloud-based solutions. Ultimately, transitioning from retrospective modeling to real-time, edge-enabled decision support represents a necessary evolution in clinical AI, requiring close collaboration between clinicians, engineers, and data scientists to enable deployable, trustworthy, and timely sepsis prediction systems.

The integration of artificial intelligence into clinical decision support systems offers improved diagnostic accuracy and efficiency, but the opacity of many machine learning models raises concerns about trust, accountability, and regulatory compliance. Explainable artificial intelligence (XAI) has been proposed to address this by making model predictions interpretable to clinicians; however, its true clinical value remains uncertain, and evaluation has not kept pace with methodological development. This systematic review aimed to identify XAI methods used in clinical decision support systems, assess how they are evaluated with clinicians, and determine whether explanations improve diagnostic accuracy, trust, mental models, and efficiency. Following PRISMA guidelines, we searched PubMed, Web of Science, IEEE Xplore, ACM Digital Library, and Scopus for studies published between 2017 and 2024. Eligible studies included original research evaluating XAI in clinical decision support systems with clinician participants and reporting quantitative or qualitative outcomes. Risk of bias was assessed using adapted QUADAS-2 and ROBIS tools, and findings were synthesized narratively with subgroup analyses. From 2,847 records, 68 studies were included. The most common XAI methods were SHAP-based feature attribution (38%), saliency or heatmap methods (29%), concept-based approaches such as TCAV (15%), and counterfactual or example-based explanations (12%). Radiology was the dominant field (54%), followed by dermatology (18%) and pathology (12%). Evaluation approaches were highly inconsistent, with few validated instruments and most studies relying on Likert-scale trust measures or qualitative feedback. Only 16% of studies showed improved diagnostic accuracy with explanations, 67% showed no significant effect, and 17% reported reduced accuracy due to over-reliance or misinterpretation. Although 82% of studies reported increased clinician trust, trust rarely correlated with actual diagnostic performance. Overall, while XAI methods are widely studied in clinical decision support, their evaluation is inconsistent and their benefits are limited. Explanations tend to increase clinician trust without reliably improving diagnostic accuracy, and may sometimes worsen performance, highlighting a trust–accuracy gap that poses important safety concerns for clinical deployment.

Large language models (LLMs) have rapidly advanced since the transformer architecture was introduced in 2017, with systems such as GPT-3, GPT-4, Med-PaLM, and Claude increasingly explored for applications in medical education, clinical documentation, decision support, and patient communication, raising both optimism and concerns regarding safety and reliability. This systematic review synthesizes evidence across studies retrieved from PubMed, arXiv, ACL Anthology, IEEE Xplore, and Google Scholar that empirically evaluated LLMs in clinical settings using quantitative performance metrics, with risk of bias assessed using an adapted PROBAST framework for machine learning research. Findings show that LLMs achieve 60–90% accuracy on USMLE-style examinations, with leading models such as GPT-4 and Med-PaLM 2 reaching or surpassing passing thresholds, while in clinical documentation tasks they can reduce physician workload by approximately 30–50% in generating outputs such as discharge summaries, though human review remains consistently required. Performance in clinical decision support is more variable and specialty-dependent, and hallucination rates ranging from 5–30% have been reported, alongside persistent issues of bias and overconfidence in incorrect outputs. Overall, while LLMs demonstrate strong capabilities in structured medical knowledge tasks and documentation support, current limitations including hallucinations, bias, and lack of prospective clinical validation prevent safe autonomous deployment, making clinician oversight and robust safety safeguards essential for any clinical use.

Anticoagulation management requires balancing multiple factors such as bleeding risk, thromboembolic risk, drug interactions, and renal function. Deep learning can assist in risk prediction, but its effectiveness relies on clinicians' ability to understand and verify the recommendations. Black-box models may recommend actions without providing clear explanations. In contrast, clinical guidelines are rule-based but not directly executable by neural models. This article introduces a neuro-symbolic XAI framework that combines deep learning predictions with explicit clinical guidelines. It includes a neural prediction module, a symbolic reasoning engine, and an integration layer for traceable justifications. The neuro-symbolic approach connects data-driven predictions to clinical rules, improving auditability and trustworthiness in decision support. This framework aims to enhance anticoagulation management by providing verifiable, clinician-understandable decision support, focusing on explainability-by-design.
