In the realm of observational clinical systems, where electronic health records (EHRs) and real-world data dominate decision-making pipelines, robust treatment-effect estimation remains a critical challenge. This conceptual manuscript introduces the treatment effect integrity network (TEIN), a novel governance model driven by causal inference principles to orchestrate monitoring, adjustment, and validation of treatment effects within heterogeneous healthcare analytics infrastructures. By integrating causal diagrams, counterfactual reasoning, and dynamic adjustment mechanisms, TEIN addresses biases inherent in observational data, such as confounding and selection effects, without relying on empirical datasets or model training. The architecture emphasizes interoperability across clinical AI systems, facilitating seamless integration into EHR intelligence ecosystems and decision-support pipelines. Key components include a causal mapping layer for identifying potential biases, a governance orchestration module for real-time effect monitoring, and a feedback topology that propagates integrity signals through clinical workflows. Theoretical formulas are presented to interpret risk propagation in causal chains and governance load under varying observational constraints. This model advances AI governance in healthcare by providing a structured approach to maintaining the reliability of treatment effects, ultimately supporting ethical deployment in observational settings. Through literature synthesis, we highlight alignments with existing clinical AI frameworks while underscoring TEIN’s unique focus on causal-driven governance. Implications for clinical practice include enhanced decision confidence and reduced monitoring burdens in resource-constrained environments.

Ultimately, EHART represents a paradigm for future-proofing hospital intelligence in real-time clinical contexts, balancing innovation with regulatory compliance.

The integration of artificial intelligence (AI) into healthcare systems marks a fundamental shift from isolated predictive analytics tools to embedded, scalable architectures that support autonomous governance. This narrative review synthesizes 28 peer-reviewed publications from leading journals to examine AI’s role across healthcare infrastructure and clinical analytics. Early work established deep learning foundations for risk prediction, diagnostic support, and prognostic modelling using multimodal data. These capabilities rapidly evolved into system-level applications that enhance data ingestion, real-time inference, and operational optimisation across entire care ecosystems.By the early 2020s, attention turned to deployment realities, including clinician acceptance, cost-effectiveness, and integration into existing workflows. Frameworks for responsible implementation emerged alongside regulatory perspectives that emphasise safety, equity, and continuous oversight. Recent contributions highlight the transition toward closed-loop systems in which predictive outputs inform decisions, trigger interventions, and feed outcome data back for model recalibration. Governance architectures now address ethical challenges, explainability gaps, and the move from generalist to specialised medical AI.This review organises the literature through an original systems-level lens spanning four interconnected pillars—data foundations, analytic intelligence, deployment mechanisms, and governance layers—rather than replicating prior application-specific taxonomies. Cross-study analysis reveals consistent patterns: predictive analytics serve as the foundational engine, clinical decision support acts as the execution layer, closed-loop feedback enables adaptation, and governance ensures sustainable autonomy. The synthesis demonstrates that AI is no longer an adjunct technology but a core infrastructural element reshaping how healthcare systems ingest, process, act upon, and learn from data at scale.Trajectory as a coherent progression toward autonomous yet human-centred governance, the review provides clinicians, system architects, and policymakers with a unified understanding of current capabilities and the infrastructural requirements for responsible scaling.

Foundation models, characterized by their large-scale pretraining on diverse datasets, represent a transformative paradigm in artificial intelligence (AI) applications for healthcare systems and analytics. These models, often based on transformer architectures, enable generalist capabilities that extend beyond narrow task-specific AI, facilitating integration into complex healthcare infrastructures. This review synthesizes recent literature on the architectural integration of foundation models into healthcare systems, emphasizing their role in enhancing clinical analytics, decision support, and operational efficiency while addressing critical oversight considerations, including ethical, regulatory, and safety frameworks.In healthcare systems, foundation models are increasingly deployed to process multimodal data streams, including electronic health records (EHRs), medical imaging, and real-time patient monitoring. Architectural integration involves embedding these models within hospital information systems, enabling seamless data ingestion, inference, and feedback loops. For instance, models like those adapted from large language models (LLMs) support natural language processing for EHR mining, predictive analytics for disease progression, and generative tasks for synthetic data augmentation. Oversight considerations are paramount, encompassing regulatory compliance, bias mitigation, and human-AI collaboration protocols to ensure patient safety and equity.The synthesis highlights key architectural patterns: federated learning for privacy-preserving model training, hybrid human-AI workflows for clinical decision-making, and adaptive systems for continuous model recalibration. Analytics applications span precision medicine, where foundation models integrate genomic and clinical data for personalized interventions, to population health management, optimizing resource allocation through predictive modeling. Ethical oversight includes checklists for AI deployment in low- and middle-income countries (LMICs), emphasizing equitable access and cultural adaptability.Challenges in integration include data interoperability, model interpretability, and scalability in resource-constrained settings. Regulatory imperatives call for validation frameworks and safety standards to govern the rollout of generative AI. This review provides an original systems-level framing, structuring the discourse around data-to-decision pipelines, governance overlays, and evaluative metrics for sustainable adoption.Ultimately, foundation models hold promise for closed-loop healthcare systems, where AI-driven insights inform interventions and feedback refines models iteratively. However, rigorous oversight is essential to balance innovation with accountability, ensuring these technologies augment rather than disrupt clinical workflows. By synthesizing high-impact publications, this narrative review offers integrative insights for researchers, clinicians, and policymakers navigating AI-enabled healthcare transformation.

Patient safety remains a paramount concern in healthcare systems, where incident narratives provide rich, unstructured evidence for identifying root causes and enhancing learning mechanisms.

Key components include a unique layered structure for theme extraction and bidirectional feedback topologies to integrate evidence into learning cycles. The discussion explores implications for clinical deployment, data modality integration, and ethical governance, highlighting how this approach can theoretically mitigate systemic vulnerabilities. Ultimately, this work advocates for a shift toward narrative-driven, evidence-structured intelligence in patient safety, promoting proactive theme-based interventions in dynamic healthcare settings.

In the rapidly evolving landscape of digital pathology, the exponential growth of specimen data volumes poses significant challenges to timely and accurate diagnostic workflows. This conceptual manuscript introduces a novel prioritization framework designed to enhance the triage of high-risk specimens within queue-aware systems, ensuring that critical cases receive expedited review without compromising overall system integrity. Drawing on theoretical principles from systems architecture and healthcare analytics, we propose the specimen prioritization and queue intelligence network (SPQIN), a multi-layered orchestration model that integrates dynamic queue monitoring, risk assessment heuristics, and adaptive feedback topologies to mitigate bottlenecks in pathology laboratories. The framework emphasizes infrastructural resilience, incorporating interpretive formulas for risk propagation and resource allocation to optimize workflow efficiency theoretically. By synthesizing recent literature on artificial intelligence applications in digital pathology, we highlight how SPQIN addresses governance constraints, such as ethical prioritization and data modality integration, in clinical deployment environments. This work underscores the potential for queue-aware triage to transform high-risk specimen review, fostering a more responsive and equitable diagnostic ecosystem. While devoid of empirical validation, the conceptual design offers a blueprint for future infrastructural advancements in AI-driven healthcare systems, promoting theoretical discussions on scalability and interoperability.

In the evolving landscape of healthcare systems, ensuring adherence to clinical guidelines through order-sets remains a critical challenge, particularly when temporal dynamics influence decision-making processes. This conceptual manuscript introduces a novel framework for modeling guideline adherence as temporal logic constructs, enabling systematic conformance verification within order-set evaluation environments. By leveraging linear temporal logic (LTL) and computational tree logic (CTL) principles, the proposed system architecture facilitates the theoretical assessment of sequential and branching compliance pathways without relying on empirical data or simulations. Key components include a layered temporal abstraction module, a verification engine for detecting deviations in real-time clinical workflows, and a feedback topology that integrates governance constraints to mitigate potential risks. The framework emphasizes infrastructural uniqueness by incorporating a unique acronym, TCV-OS (temporal conformance verification for order-sets), with distinct layers for logic encoding, state monitoring, and adaptive reconciliation. Conceptual formulas are presented to interpret risk propagation across temporal states and decision confidence in adherence scenarios. This work synthesizes recent literature on temporal reasoning in medical decision support, highlighting gaps in current approaches and proposing architectural innovations for enhanced guideline orchestration. Ultimately, the framework offers a theoretical foundation for improving healthcare analytics integrity, fostering safer and more efficient order-set deployments in diverse clinical settings.

Nursing workload has long been recognized as a critical but under-theorized determinant of patient safety. This conceptual systems article reframes workload not as a static staffing metric but as a dynamic, measurable safety signal whose temporal and structural characteristics can be modeled to detect emerging risk states before adverse events materialize. Drawing exclusively on peer-reviewed literature published, the manuscript synthesizes evidence that elevated workload correlates with missed care, falls, medication errors, and burnout, yet existing approaches remain fragmented across isolated predictive models or retrospective acuity tools.To address this architectural gap, the article introduces the TASK-RISK framework—a novel, task-structured orchestration infrastructure that decomposes clinical activities into granular, temporally anchored units, fuses them into composite safety signals, and propagates those signals through a closed-loop detection topology. The framework is purely conceptual, specifying layer definitions, feedback mechanisms, and interpretive mathematical formalisms without empirical training or performance claims. Its five-layer architecture—task acquisition, workload quantification, signal generation, risk propagation, and governance feedback—operates entirely within existing electronic health record and sensor infrastructures, thereby offering a scalable blueprint for proactive safety governance. Theoretical implications for clinical deployment, ethical oversight, and system drift management are delineated. The manuscript establishes workload as a first-class safety signal and supplies the infrastructural scaffolding required for its integration into next-generation healthcare analytics platforms.

Multi-agent systems (MAS) represent a paradigm shift in artificial intelligence applications for healthcare operations, enabling distributed, autonomous entities to collaborate in complex environments characterized by uncertainty, heterogeneity, and real-time demands. This narrative review synthesizes recent advancements in MAS for healthcare systems and analytics, focusing on coordination theory, safety constraints, and implementation considerations. We examine how MAS facilitates intelligent coordination among agents—such as AI models, human clinicians, and IoT devices—to optimize operational workflows, enhance clinical decision-making, and ensure patient safety. Coordination theory in MAS underscores the mechanisms for agent interaction, including negotiation protocols, consensus algorithms, and hierarchical structures, which are critical for synchronizing tasks in healthcare settings like emergency response and chronic disease management. For instance, MAS enables adaptive resource allocation in hospitals by modeling agents as decision-makers that negotiate bed assignments or staff scheduling based on real-time data inputs. Safety constraints emerge as a pivotal concern, encompassing formal verification methods, fault-tolerant designs, and ethical safeguards to mitigate risks such as erroneous agent decisions leading to adverse patient outcomes. Implementation considerations address scalability, interoperability with legacy systems, and regulatory compliance, highlighting challenges in deploying MAS in fog-cloud architectures for remote monitoring. The review integrates a systems-level perspective, illustrating how MAS evolve from isolated AI tools to interconnected ecosystems that support closed-loop healthcare processes—from data acquisition to intervention feedback. We propose an original interpretive framework that structures MAS across layers: perceptual (data sensing), cognitive (analytics and decision fusion), coordinative (agent interaction), and governance (safety and oversight). This framework reveals cross-study insights, such as the role of large language models (LLMs) in augmenting agent rationality and the integration of digital twins for simulation-based safety testing. Comparative analysis shows that while MAS excel in dynamic environments like cardiology case retrieval or pain management, persistent gaps in standardization hinder widespread adoption. By synthesizing these elements, the review offers novel insights into MAS as enablers of resilient healthcare infrastructure, emphasizing the need for hybrid human-AI coordination to balance autonomy with oversight. Future implications include advancing MAS toward predictive analytics in personalized medicine, with recommendations for interdisciplinary research to address implementation barriers. Ultimately, this work advocates for MAS as foundational to next-generation healthcare analytics, promoting efficiency, equity, and safety in operational contexts.

The integration of social determinants of health (SDoH) into artificial intelligence (AI) systems for healthcare represents a pivotal advancement in addressing inequities within clinical analytics and decision-making frameworks. SDoH encompass socioeconomic, environmental, and behavioral factors that profoundly influence health outcomes, yet their incorporation into AI models has been inconsistent, often exacerbating biases rather than mitigating them. This narrative review synthesizes recent literature on strategies for embedding SDoH data into AI pipelines, elucidates mechanisms of bias propagation, and evaluates approaches to equity assessment in healthcare systems. Drawing from peer-reviewed publications, we highlight the evolution of AI applications in healthcare analytics, where machine learning algorithms increasingly process electronic health records (EHRs), wearable data, and population-level datasets to predict risks and optimize interventions. However, without deliberate integration of SDoH, these systems risk perpetuating disparities, as evidenced by models that underperform for underrepresented groups due to skewed training data. Integration strategies range from data augmentation techniques, such as linking EHRs with geospatial SDoH indices, to hybrid modeling approaches that fuse clinical variables with socioeconomic proxies. For instance, federated learning frameworks enable cross-institutional data sharing while preserving privacy, facilitating broader SDoH representation. Bias mechanisms are multifaceted, including selection bias from non-diverse datasets, algorithmic amplification of historical inequities, and deployment biases in real-world settings where AI outputs influence resource allocation. Studies demonstrate how unaddressed confounders, like zip code-based proxies for race or income, can lead to discriminatory predictions in areas such as readmission risk or treatment recommendations. Equity evaluation methodologies emphasize fairness metrics, such as demographic parity and equalized odds, adapted for healthcare contexts. Prospective audits, involving diverse stakeholder input, are recommended to assess model performance across SDoH strata. Consensus emerges on the need for governance structures that incorporate ethical AI principles, including transparency in SDoH feature engineering and continuous monitoring for drift. Challenges persist in standardizing SDoH data collection, with calls for interoperable ontologies to enhance AI generalizability. This review proposes a systems-level framework for SDoH-aware AI, advocating for closed-loop systems that integrate feedback from equity audits into model retraining cycles. Ultimately, advancing SDoH integration in healthcare AI requires interdisciplinary collaboration between clinicians, data scientists, and policymakers to foster equitable systems. By prioritizing bias mitigation and equity-centric design, AI can transition from a tool that mirrors societal inequities to one that actively reduces them, promoting health justice in analytics-driven care. Future directions include scalable implementations in low-resource settings and regulatory frameworks to enforce SDoH considerations. This synthesis underscores the transformative potential of SDoH-informed AI while cautioning against unchecked deployment that could widen health gaps.

The integration of artificial intelligence into healthcare systems has transitioned from isolated diagnostic tools to comprehensive workflow automation platforms that fundamentally reshape clinical operations, decision cycles, and accountability frameworks. This narrative review synthesizes studies that examine how AI-driven task modeling, human–AI interaction dynamics, and evolving accountability structures collectively enable scalable, safe, and ethically grounded automation across healthcare analytics and delivery infrastructures. Rather than cataloging isolated applications, the analysis adopts an original systems-level lens that organizes the literature into four interdependent layers—data orchestration, model orchestration, deployment orchestration, and governance orchestration—revealing recurring patterns of closed-loop intelligence that link real-time data ingestion to automated intervention and continuous recalibration. Task modeling emerges as the foundational mechanism through which heterogeneous clinical workflows are decomposed into machine-executable primitives while preserving human oversight at critical decision nodes. Multiple integrative reviews demonstrate that well-designed task ontologies reduce cognitive burden on clinicians by 30%–50% in high-volume settings such as nursing documentation, pathology slide triage, and echocardiographic measurement, yet success critically depends on explicit representation of human factors, including workload, trust calibration, and exception-handling protocols. Human factors literature further highlights the bidirectional influence between automation and clinician performance. While AI scribes and large language model-assisted note generation improve throughput, they simultaneously introduce new forms of automation bias and alert fatigue that must be mitigated through adaptive interface design and real-time transparency mechanisms. Accountability structures constitute the least mature yet most decisive layer of AI-enabled healthcare automation. Governance models that embed continuous human–AI shared liability, audit trails for every automated decision, and dynamic recalibration triggers are shown to be essential for regulatory acceptance and clinical adoption. Studies of real-world deployments in pathology foundation models and closed-loop infection prevention systems illustrate that accountability is not an afterthought but an infrastructural requirement: without traceable lineage from raw data through model inference to clinical action and feedback, organizations cannot fulfill medico-legal or ethical obligations. This review contributes an original integrative framework—the clinical intelligence loop—that formalizes the end-to-end automation architecture as a continuous cycle of data ingestion, task-modeled inference, human-augmented decision fusion, intervention execution, outcome monitoring, and governance-driven recalibration. Cross-study synthesis reveals that systems achieving sustained performance do so by maintaining tight coupling across all five stages rather than optimizing any single component in isolation. The analysis underscores that workflow automation in healthcare AI succeeds only when task modeling is human-centered, human factors are explicitly engineered into the loop, and accountability is infrastructural rather than retrofitted. These insights provide both theoretical scaffolding and practical guidance for health-system leaders, regulators, and technology developers seeking to scale responsible AI automation beyond pilot projects.

The rapid expansion of unstructured narrative data within patient safety event (PSE) reporting systems presents both a valuable source of safety intelligence and a major analytical challenge for healthcare organizations. Traditional manual review processes are labor-intensive, subjective, and incapable of scaling to the vast volumes of incident reports generated across modern health systems. Artificial intelligence techniques, particularly natural language processing and machine learning, provide scalable approaches for extracting meaningful insights from these narratives. This narrative review synthesizes advances in AI-enabled PSE analytics across three interconnected domains: automated narrative mining, data-driven taxonomy development, and integration within learning health systems that transform safety data into continuous improvement cycles. Evidence indicates that AI methods can improve event classification, accelerate detection of emerging safety signals, and reduce the analytical burden on safety teams. However, challenges remain regarding model generalisability, interpretability, and governance. AI-driven narrative analytics is emerging as a foundational component of next-generation safety intelligence infrastructures.

Wearable and mobile sensing technologies are transforming healthcare by enabling continuous monitoring, real-time analytics, and personalized interventions. This narrative review explores recent advances in artificial intelligence (AI)–driven healthcare analytics, focusing on validation frameworks, drift detection, and generalization challenges associated with wearable sensing systems. Modern wearable devices equipped with biosensors capture physiological signals such as heart rate, activity, and stress indicators, while AI algorithms analyze multimodal data to generate actionable clinical insights. Ensuring reliability requires robust validation strategies that address sensor accuracy, data integrity, and clinical relevance in real-world settings. Drift detection methods help maintain model performance despite environmental changes and user variability. At the same time, generalization techniques support reliable deployment across diverse populations and clinical contexts, advancing scalable and adaptive digital healthcare systems.

Antimicrobial resistance (AMR) is a major global health crisis, particularly due to multidrug-resistant gram-negative bacteria that are difficult to treat because of their impermeable outer membrane and strong efflux mechanisms, making antimicrobial peptides (AMPs) a promising alternative owing to their broad-spectrum activity and rapid bactericidal effects, although their clinical translation is limited by instability, production costs, and toxicity to human cells; meanwhile, traditional experimental discovery of AMPs is slow and expensive, and existing computational methods often optimize only antimicrobial activity while neglecting toxicity or diversity, leading to unsafe or narrow solutions, while reinforcement learning approaches may suffer from mode collapse and limited exploration of sequence space; to address these limitations, this work proposes a generative flow networks (GFlowNets)-based framework for multi-objective AMP design against gram-negative pathogens, in which a sequence generator constructs peptides stepwise and is guided by a reward function that integrates predicted antimicrobial activity and human cell toxicity from separate machine learning models, enabling simultaneous optimization of efficacy and safety; unlike conventional generative models, GFlowNets sample sequences proportional to reward, promoting diverse outputs that span the Pareto frontier of activity-toxicity trade-offs, while also allowing conditioning on desired properties and modular improvement of predictive components over time; overall, this framework provides a principled and scalable approach to antimicrobial peptide discovery that balances potency, safety, and diversity, potentially accelerating the identification of therapeutic candidates for combating antimicrobial resistance.

Postpartum hemorrhage (PPH) is the leading cause of maternal mortality worldwide, accounting for 25–30% of deaths, particularly in low-resource settings, and early identification of high-risk patients during labor could enable timely interventions such as uterotonic administration, blood preparation, and escalation of care; however, current risk stratification models rely mainly on static antepartum factors and fail to incorporate dynamic intrapartum physiological changes. Existing tools, including those from the California Maternal Quality Care Collaborative, use baseline maternal characteristics such as prior PPH, BMI, parity, and comorbidities, but do not capture continuously evolving labor data, despite intrapartum signals like fetal heart rate patterns, maternal vital sign trends, and labor progression metrics containing rich predictive information that remains underused in real-time decision-making, while clinical judgment is limited by inter-observer variability and inability to integrate complex temporal trends. To address this gap, we propose an explainable gradient boosting machine framework for real-time PPH risk prediction that integrates electronic fetal monitoring parameters (baseline rate, variability, decelerations), maternal vital signs (heart rate, blood pressure, temperature, oxygen saturation), and labor progression features (cervical dilation, contraction frequency, stage duration, and oxytocin use), producing continuously updated risk scores throughout labor. The system combines a gradient boosting model (XGBoost or LightGBM), a SHAP-based explainability module, a real-time feature extraction pipeline, and a clinician-facing dashboard that displays risk scores and key contributing factors, where SHAP provides both global and patient-specific interpretability by identifying how features such as tachysystole or prolonged labor stages influence predictions, thereby improving transparency and clinical trust. Overall, this framework enables dynamic, interpretable PPH risk assessment using routinely collected intrapartum data, combining predictive accuracy with explainability to support earlier detection of hemorrhage risk and more timely, targeted interventions.

During the COVID-19 pandemic, machine learning models developed in high-resource hospitals achieved strong performance in predicting outcomes such as mortality, ICU admission, and mechanical ventilation, but their accuracy often degrades when applied to low-resource settings due to differences in patient populations, disease severity, clinical practices, and documentation quality. Low-resource hospitals also face limited patient volumes, incomplete labeled data, and strict privacy regulations (e.g., HIPAA and GDPR), which prevent centralized data sharing and hinder independent model development, creating a barrier to equitable AI deployment. To address this, we propose a federated transfer learning framework that adapts prognostic models from high-resource to low-resource hospitals without exchanging patient-level data. The approach transfers only aggregate statistics (e.g., feature means, variances, class-conditional distributions, and correlations) via a secure lightweight protocol, enabling target hospitals to align feature distributions using domain adaptation techniques and fine-tune models on small local datasets. The framework includes source model training, statistical aggregation, secure transmission, and target-side adaptation modules, ensuring no raw patient data leaves any institution. By relying on aggregate statistics, the method preserves privacy while mitigating domain shift and maintaining clinical utility across diverse healthcare environments. This scalable and privacy-preserving framework supports broader deployment of COVID-19 predictive models and provides a generalizable strategy for other medical conditions with heterogeneous healthcare settings.

Surgical site infections (SSIs) remain a significant source of postoperative morbidity despite established guidelines for perioperative antibiotic prophylaxis. Current protocols emphasize fixed preoperative timing and interval-based intraoperative redosing, yet fail to account for patient heterogeneity, pharmacokinetic variability, and uncertainty in procedure duration. This study proposes a hierarchical reinforcement learning (HRL) framework for personalized optimization of antibiotic prophylaxis across the perioperative timeline. The framework decomposes decision-making into two coordinated levels: a high-level policy that determines optimal preoperative antibiotic timing based on predicted procedure duration and patient-specific infection risk, and a low-level policy that adaptively manages intraoperative redosing using real-time updates on elapsed time, remaining duration, and cumulative drug exposure. Procedure duration is estimated using machine learning models that provide both point predictions and uncertainty intervals, enabling risk-sensitive decision-making. The problem is formalized as a Markov decision process with a reward structure balancing SSI prevention against antibiotic stewardship, incorporating penalties for unnecessary dosing and suboptimal timing. Off-policy evaluation using historical surgical data is proposed to assess performance relative to guideline-based and clinician-driven strategies. By integrating predictive modeling with multi-timescale decision optimization, the framework aims to reduce SSI incidence while minimizing antibiotic overuse. This approach highlights the potential of reinforcement learning to advance precision perioperative care and improve clinical outcomes through adaptive, data-driven prophylaxis strategies.

Intensive care unit (ICU) data consist of high-frequency multivariate time series, including vital signs, laboratory results, and hemodynamic variables, which are crucial for clinical decision-making and predictive modeling. However, these data are frequently incomplete due to monitor interruptions, clinical workflows, and selective measurement, with missing rates ranging from 20% to over 80% depending on the variable. Missingness in ICU time series is often not random, as sicker patients tend to be monitored more frequently, creating a missing not at random (MNAR) mechanism. Conventional imputation methods such as mean filling, interpolation, and multiple imputation assume random missingness and therefore introduce bias and distort clinical signals under MNAR conditions. We propose a variational recurrent neural network (VRNN) with stochastic attention to impute ICU time series under MNAR settings. The framework integrates latent state modeling of physiological dynamics, stochastic attention over observed measurements using Gumbel-Softmax sampling, and a missingness pattern encoder that explicitly models the observation process. An imputation decoder generates probabilistic estimates of missing values conditioned on latent states, attention context, and missingness structure. This framework enables uncertainty-aware and potentially unbiased imputation in ICU time series by jointly modeling physiological dynamics and missingness mechanisms. It combines variational inference and stochastic attention to address systematic bias in conventional approaches, with future work needed to validate performance on real-world ICU datasets.

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.

Oncology drug development is an expensive and high-failure process, with costs exceeding two billion dollars per approved drug and success rates below 10%. Deep learning has recently been explored as a strategy to improve efficiency across the drug discovery pipeline. This systematic review evaluates its application in target identification, compound screening and de novo drug design, and clinical trial optimization. Following PRISMA 2020 guidelines, multiple databases were searched and studies were screened using predefined inclusion criteria, with risk of bias assessed via established tools. The literature shows that graph neural networks and transformer-based models are the most widely used architectures, particularly in early-stage discovery tasks. Although many studies report strong in silico performance, often with AUC values above 0.80, only a small proportion demonstrate experimental or clinical validation. Overall, deep learning significantly advances computational drug discovery in oncology, but translation into clinically validated therapies remains limited, especially in trial optimization, highlighting the need for stronger prospective and experimental validation frameworks.

Sepsis continues to be a major contributor to morbidity and mortality among hospitalized patients globally, especially within intensive care and emergency departments, where rapid recognition is essential for improving survival through timely treatment. In recent years, machine learning approaches have gained attention for their ability to predict sepsis onset using routinely collected electronic health record data. This systematic review, conducted in accordance with PRISMA 2020 guidelines, synthesizes evidence from studies published between 2017 and 2025, focusing on model architectures, feature selection and engineering strategies, prediction time horizons, and validation methodologies. Searches across major biomedical and informatics databases identified 67 eligible studies. The included literature shows that logistic regression, ensemble tree-based algorithms, and deep learning models are most frequently applied for sepsis prediction tasks. However, the majority of studies rely on retrospective datasets with internal validation, while only a limited number incorporate prospective or real-world validation frameworks. Overall, although reported model performance is often strong in retrospective analyses, a consistent decline in accuracy is observed when models are evaluated in real clinical environments. These findings highlight that prospective validation and improved generalizability are still underdeveloped areas, underscoring the need for future research to emphasize real-time deployment and robust external validation before clinical integration.

Synthetic electronic health record (EHR) data generation has emerged as a potential solution to balancing clinical data accessibility with patient privacy, using generative artificial intelligence to simulate tabular, longitudinal, and textual health records without exposing identifiable patient information. This critical review, informed by PRISMA-ScR methodology, examines studies published between 2017 and 2025 focusing on generative models for synthetic EHR creation, with particular attention to privacy risks, data fidelity, downstream task utility, and ethical or regulatory considerations. A total of 67 studies were included after systematic screening, showing a dominance of GAN-based approaches alongside growing use of diffusion models and large language models in recent years, although privacy assessment and benchmarking practices remain inconsistent. Overall, the evidence suggests that while synthetic EHR data can facilitate data sharing, research, and model development, achieving a balance between realism, utility, and privacy remains challenging, as high statistical fidelity does not necessarily translate into clinical usefulness and strong downstream performance does not ensure adequate privacy protection.

Sleep disorders, including obstructive sleep apnea, insomnia, restless legs syndrome, narcolepsy, and central sleep apnea, represent a major public health burden. Polysomnography is the diagnostic gold standard but is resource-intensive, leading to increasing use of home sleep apnea testing and wearable devices to improve accessibility. This systematic review evaluates deep learning models in sleep medicine across polysomnography, home sleep apnea testing, and wearable data, focusing on architectures, signal types, validation approaches, diagnostic tasks, and clinical readiness. A PRISMA 2020–compliant search was conducted in PubMed, IEEE Xplore, Scopus, and Web of Science for studies published from 2017 to 2025, including those applying deep learning for sleep staging, apnea/hypopnea detection, or sleep disorder diagnosis using PSG, HSAT, or wearable-derived signals. Twenty-nine studies were included. Convolutional neural networks were the most widely used architecture, often combined with recurrent or hybrid models for temporal dependencies, while transformer-based models have recently emerged for long-sequence sleep analysis. Deep learning methods demonstrate strong performance in sleep staging and respiratory event detection, especially using polysomnography data. However, limited external validation, heterogeneous datasets, and a lack of prospective clinical deployment remain major barriers to clinical translation.

Rare diseases are challenging for AI development due to sparse patient populations, fragmented expertise, and strong inter-site variability, making federated learning a promising privacy-preserving solution for multi-institutional model training. This systematic review evaluates federated learning approaches for rare disease diagnosis and related data-scarce clinical settings, with emphasis on handling extreme data scarcity, class imbalance, heterogeneity, and privacy constraints. A PRISMA 2020-compliant search of PubMed, IEEE Xplore, Scopus, Web of Science, and arXiv (2017–2025) identified 2,015 records, with 56 studies included after screening. The most commonly used strategies included FedProx-based optimization, personalized federated learning, class-aware aggregation, generative data augmentation, and domain adaptation techniques. Overall, standard federated averaging is often insufficient under severe scarcity and distribution shift, while hybrid approaches combining personalization, augmentation, and domain adaptation show greater promise for improving performance in rare disease applications.

Public health emergencies reveal critical weaknesses in healthcare supply chains, especially when PPE demand outpaces procurement and distribution capacity, making predictive analytics an important tool for forecasting demand and improving allocation during crises. This systematic review evaluates predictive analytics models for PPE demand forecasting and distribution optimization during public health emergencies, focusing on model types, data sources, validation approaches, performance metrics, equity considerations, and implementation readiness. Following PRISMA 2020 guidelines, searches were conducted in PubMed, Web of Science, Scopus, IEEE Xplore, and Google Scholar for studies published between 2017 and 2025, yielding 2,847 records, of which 35 met inclusion criteria. Included studies comprised time series and statistical models (34%), machine learning and hybrid approaches (29%), optimization methods (26%), and simulation or digital twin frameworks (11%), with limited evidence of real-world deployment. Overall, findings indicate that predictive analytics can enhance PPE supply chain resilience by improving demand forecasting, allocation decisions, and scenario testing, but widespread adoption is limited by poor data interoperability, insufficient prospective validation, weak equity integration, and limited operational integration into healthcare decision systems.

Chronic obstructive pulmonary disease (COPD) is a leading cause of death, with exacerbations worsening functional decline, reducing quality of life, and increasing healthcare use. Current management remains reactive, with treatment often initiated only after symptoms worsen. Existing monitoring approaches struggle to distinguish between clinically significant deterioration and normal variability, leading to delayed intervention. This article proposes a digital twin framework combining patient-specific respiratory models with real-time wearable data to predict and manage COPD exacerbations proactively. The framework includes a mechanistic lung model, continuous data ingestion, a data assimilation module, an exacerbation prediction layer, and an alert system, enabling early detection of physiological deviations before severe symptoms arise. By supporting pre-emptive telehealth, medication adjustments, and patient self-management with clinician oversight, this approach could shift COPD care from reactive to personalized, proactive management, pending robust modeling, reliable sensing, and real-world validation.
