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.

This narrative review synthesizes recent literature on AI governance in healthcare, focusing on systems-level infrastructure and clinical analytics. Drawing from peer-reviewed publications, we examine how AI tools enhance healthcare delivery through data-driven insights while addressing ethical, regulatory, and operational challenges.Central to AI governance is transparency, which involves making algorithmic processes interpretable to clinicians and stakeholders. Studies highlight the need for explainable AI models in clinical decision-making, where opaque “black-box” systems can undermine trust and accountability. For instance, frameworks for implementing machine learning in healthcare emphasize ethical considerations, such as disclosing model limitations and decision rationales to prevent misinformed clinical actions. Bias mitigation emerges as a critical pillar, with research demonstrating how algorithmic biases in electronic health records can perpetuate health disparities, particularly among underrepresented populations. Strategies include proactive monitoring of algorithms for equity, incorporating diverse datasets during development, and post-deployment audits to detect and correct biases.Lifecycle monitoring models ensure sustained performance and safety of AI systems over time.

Sepsis is a leading cause of ICU mortality, and early detection is critical for improving patient outcomes. However, existing machine learning models often rely on hourly aggregated data, limiting their ability to capture rapid physiological changes, and frequently lack interpretability, reducing clinical trust and usability. This paper proposes a conceptual framework that integrates Temporal Convolutional Networks (TCNs) with an attention mechanism to analyze high-frequency, minute-level vital sign data for early sepsis prediction. The architecture includes a data input layer, a TCN-based feature extractor with causal dilated convolutions and residual connections, an attention module for identifying clinically relevant time points and variables, and a prediction head that estimates the risk of sepsis within a 6-hour horizon. The proposed approach enables efficient parallel processing, improved temporal sensitivity, and enhanced interpretability compared to recurrent models. While offering advantages in real-time prediction and explainability, challenges remain in handling missing data, ensuring generalizability across ICUs, and minimizing false alarms for clinical deployment.
Over the past five years, sepsis prediction models have reported strong retrospective performance, often exceeding AUROC 0.85–0.90 by leveraging vital signs, laboratory data, and machine learning to predict sepsis earlier than clinical recognition. However, despite these results, bedside adoption remains minimal, and external or prospective validations frequently show substantial performance decline, with clinicians still relying on traditional criteria such as qSOFA and SIRS. This position paper argues that AUROC is an insufficient and potentially misleading metric for clinical deployment, as it reflects retrospective rank discrimination rather than real-world utility, calibration, or actionable impact. High AUROC scores often conceal poor threshold selection, excessive alert burden, and clinically unacceptable alarm fatigue, while retrospective evaluations create an overly optimistic view that fails in real-time settings. We propose shifting evaluation toward clinically meaningful metrics such as net benefit, alert burden per patient-day, and number needed to alert at clinician-defined thresholds, alongside earlier incorporation of workflow requirements. Ultimately, the continued dominance of AUROC-centric evaluation represents a systemic mismatch between model development and clinical reality, limiting sepsis prediction tools from achieving meaningful impact at the bedside.
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.
Sepsis remains a major cause of mortality in intensive care units worldwide, with an estimated 49 million cases and over 11 million deaths annually, highlighting the need for earlier detection to improve outcomes. This systematic review synthesizes evidence on machine learning models for early sepsis prediction in adult ICU patients from 2017 to 2021, focusing on prediction horizons, data modalities, and validation approaches. A comprehensive search of PubMed, Embase, IEEE Xplore, ACM Digital Library, and arXiv identified studies meeting criteria for ICU-based sepsis prediction with at least a 4-hour forecast window, following PRISMA guidelines. Of 1,478 records screened, 35 studies were included, with prediction horizons ranging from 4 to 24 hours and most relying on hourly vital sign data and internal validation. Reported performance varied widely depending on horizon length, data sampling, and validation rigor, with external validation generally producing lower but more realistic results. Overall, while machine learning models show promising predictive ability, limitations in generalizability and standardization remain, emphasizing the need for stronger validation frameworks and reporting practices to support clinical translation.
Acute kidney injury (AKI) is a common and serious condition in critical care, making early prediction essential for timely intervention, reduced mortality, and lower healthcare costs. Machine learning methods using electronic health records have shown promise in identifying at-risk patients, but their performance is often limited by reliance on single-institution datasets and poor generalizability across populations. Privacy regulations such as HIPAA and GDPR further restrict cross-hospital data sharing, hindering the development of more robust models.To address these challenges, this study proposes a federated learning–based framework for AKI prediction, enabling multiple hospitals to collaboratively train models without exchanging raw patient data. Each institution acts as a local client that trains on its own data and shares only model updates, which are aggregated into a global model. The framework incorporates standardized feature processing, secure aggregation, and communication-efficient strategies to ensure scalability across heterogeneous healthcare environments.This privacy-preserving approach improves model generalization by leveraging diverse multi-institutional data while maintaining regulatory compliance. Although it introduces challenges such as communication overhead and convergence complexity, these are mitigated through optimized aggregation methods. Overall, the proposed framework enhances predictive performance, supports clinical decision-making, and offers a scalable foundation for future privacy-aware healthcare AI systems in AKI management.
The Berlin definition of ARDS provides standardized diagnostic criteria based on acute onset within one week of a known insult, bilateral chest imaging opacities not explained by other causes, respiratory failure not due to cardiac issues or fluid overload, and impaired oxygenation measured by the PaO₂/FiO₂ ratio, enabling consistent identification in intensive care; however, its clinical use is limited by variability in imaging interpretation and the need for rapid decision-making, often causing delays and inconsistent diagnoses. Current practice relies heavily on subjective assessment of chest X-rays and limited integration of clinical notes and laboratory trends, resulting in moderate inter-observer agreement and reduced diagnostic reliability. To overcome these challenges, a multimodal transformer framework is proposed that integrates chest X-rays, clinical notes, and laboratory data using vision transformers, BERT-based text encoders, and temporally aware lab embeddings, with cross-modal attention enabling interaction across data types and a fusion module producing final ARDS probability estimates. This integrated approach improves diagnostic accuracy by combining complementary information, enhances interpretability through attention mechanisms, and offers a more objective and timely method for ARDS detection, with potential to support earlier intervention and better outcomes in critically ill patients.
Septic shock, defined as sepsis with persistent hypotension despite adequate fluid resuscitation and requiring vasopressors, has a mortality rate of 30–50% despite modern treatment. Intravenous fluids remain the cornerstone of early therapy, with guidelines recommending at least 30 mL/kg of crystalloids within the first three hours. However, both insufficient and excessive fluid administration can be harmful, making individualized, data-driven management essential. Reinforcement learning (RL) has been proposed to optimize fluid and vasopressor dosing in sepsis using retrospective ICU data. While models such as the AI Clinician suggest potential survival benefits, they often prioritize long-term outcomes like mortality and overlook short-term harms such as fluid overload and organ injury, raising safety concerns. Safety constraints and harm-aware reward design are essential in RL systems for septic shock. Pure outcome optimization is insufficient, and clinical AI must include mechanisms to prevent unsafe actions and ensure adherence to safety limits. Offline RL is vulnerable to distributional shift and unsafe extrapolation. Reward functions focused only on survival ignore acute complications, leading to unsafe policies. Human-in-the-loop oversight is necessary to maintain clinical accountability and enable intervention. RL systems should include action constraints, conservative learning with uncertainty estimation, and reward penalties for fluid overload indicators. Regulatory bodies and journals should require safety validation, and clinicians must retain override authority and transparency in decision-making. RL in septic shock management must prioritize patient safety through constraints, harm-aware rewards, and clinical oversight. Without these safeguards, deployment risks patient harm and loss of trust in clinical AI.
Wearable electrocardiogram (ECG) devices such as smartwatches and ambulatory monitors generate large-scale continuous cardiac data suitable for arrhythmia detection in real-world settings. However, the development of supervised machine learning models is limited by the scarcity of expert-annotated ECG data, class imbalance due to rare arrhythmias, and privacy constraints that restrict data sharing. These challenges make it difficult for traditional deep learning approaches to scale effectively in clinical applications.This work proposes a self-supervised contrastive learning framework that leverages large volumes of unlabeled wearable ECG data to learn meaningful cardiac representations. Using ECG-specific data augmentations, the model is trained to maximize agreement between different views of the same signal while distinguishing between different segments. A deep encoder produces latent embeddings, which are optimized through a contrastive loss, and later adapted for arrhythmia classification using a lightweight classifier with minimal labeled data.The proposed approach reduces dependence on expert annotations, improves generalization across devices and populations, and supports privacy-preserving training. Overall, it offers a scalable and efficient pathway for wearable-based arrhythmia detection, potentially enabling earlier diagnosis and broader deployment of cardiac AI systems in resource-limited healthcare settings.
Polypharmacy, defined as the concurrent use of five or more medications, is highly prevalent among older adults and patients with multiple chronic conditions and is associated with an increased risk of drug–drug interactions (DDIs), leading to adverse drug events, hospitalizations, and higher healthcare costs. Existing DDI databases are often incomplete and fail to capture higher-order interactions, while many machine learning approaches overlook temporal prescription patterns and molecular structure information, limiting their effectiveness in real-world clinical settings. To address these limitations, this study proposes a graph neural network (GNN)-based framework that integrates prescription sequence data with molecular representations to improve DDI prediction. The model constructs a unified graph where drug nodes encode both known interactions and learned similarities, while a prescription sequence encoder captures temporal co-prescribing patterns and a molecular encoder processes SMILES-based structures. These multimodal representations are fused within a patient–drug interaction graph and refined using GNN layers with attention mechanisms to enhance interpretability. By combining longitudinal clinical data with chemical structure information, the framework enables more accurate, context-aware, and patient-specific prediction of DDIs, supports the identification of novel interactions, and improves risk stratification in polypharmacy settings, offering a scalable and interpretable foundation for future clinical decision support systems.
Postoperative delirium affects 10–60% of elderly surgical patients and is linked to longer hospital stays, cognitive decline, and increased mortality. Although machine learning models have been developed to predict this condition using perioperative data, most rely on point predictions that fail to express uncertainty, limiting their clinical reliability in high-stakes surgical decision-making. These models often report a single risk estimate without indicating whether predictions are supported by strong or sparse evidence, which can lead to overconfidence and potential patient harm in vulnerable populations with heterogeneous frailty and comorbidity profiles. We argue that Bayesian deep learning is essential for postoperative delirium prediction because it provides distributional outputs and uncertainty estimates that allow clinicians to assess prediction reliability. Incorporating uncertainty quantification can transform these models from opaque tools into clinically trustworthy decision aids. We recommend that uncertainty reporting be required in all predictive models for postoperative delirium and that regulatory and publication standards enforce the use of Bayesian approaches. Overall, replacing point estimates with distributional predictions is necessary to improve safety and clinical utility in perioperative care of elderly patients.
Acute ischemic stroke prediction from electronic health record time series data holds significant potential for enabling early intervention and reducing long-term disability. LSTMs have been widely used to model clinical sequences such as vital signs and laboratory trends, showing strong performance in stroke-related prediction tasks from 2018–2022. However, their sequential nature limits scalability and long-range dependency modeling in large EHR datasets. Transformers, despite transforming sequence modeling in other domains since 2017, remain underused in stroke prediction compared to LSTMs. Although early healthcare studies suggest potential benefits of attention-based models, robust validation in acute ischemic stroke contexts is still limited. Transformers offer advantages in parallel processing, long-range dependency modeling, and interpretability, but require more data and computational resources. They are likely to complement rather than replace LSTMs, with hybrid architectures providing a balanced solution for clinical time series analysis. Key themes include long-range dependency capture, parallel computation, interpretability, and data efficiency trade-offs between LSTMs and transformers. Hybrid LSTM–transformer models may offer improved performance and practicality for stroke prediction, with model selection depending on data scale and clinical constraints. Further benchmarking is needed to determine when transformers or hybrid models outperform LSTMs, guiding the development of more effective stroke prediction systems.
Surgical site infections (SSIs) affect 2–20% of surgical procedures and are a major source of postoperative morbidity, prolonged hospitalization, readmission, mortality, and healthcare costs, making prevention a key priority. Existing prediction tools such as the NNIS index and SENIC score depend on a limited set of clinical variables including wound class, ASA status, and operative duration, while failing to capture complex interactions among patients, surgeons, and comorbidities. To address this limitation, we propose a graph attention network (GAT) framework that represents each surgical case as a heterogeneous graph composed of patient, surgeon, and comorbidity nodes, with intraoperative variables included as features and attention mechanisms used to learn the most influential relationships. This approach models relational dependencies such as the interaction between surgeon experience, patient conditions, and comorbidity combinations, enabling more accurate and context-aware SSI risk prediction to support personalized preventive interventions.
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.
