The integration of artificial intelligence (AI) into healthcare systems and analytics has revolutionized clinical workflows, enabling predictive analytics, diagnostic support, and personalized interventions. However, this embedding raises profound ethical, liability, and regulatory challenges that must be addressed to ensure safe, equitable, and effective deployment. This narrative review synthesizes literature governance frameworks for AI-embedded healthcare, focusing on systems-level infrastructure and clinical analytics.Ethically, AI systems introduce risks of bias amplification, where algorithms trained on non-representative datasets perpetuate disparities in health outcomes, as seen in racial biases in risk prediction tools. Privacy concerns escalate as data mining from digital phenotyping proliferates, necessitating robust consent mechanisms and transparency in algorithmic decision-making.

Regulatory governance demands a shift from product-centric to system-view approaches, incorporating human-AI interactions, ongoing monitoring, and adaptive oversight, as proposed for AI/ML-based software as medical devices (SaMD).In healthcare systems, AI analytics facilitate end-to-end loops from data ingestion to intervention feedback, but require governance to mitigate distributional shifts and automation complacency. Clinical decision support systems (CDSS) exemplify this, where AI augments human judgment but risks reinforcing outdated practices without ethical recalibration. Radiology is a key domain, and AI in imaging analytics underscores the need for multisociety ethical statements and regulatory vetting.This review provides an original synthesis that structures AI governance across data ecosystems, model transparency, deployment integrity, and feedback mechanisms. It underscores the imperative for interdisciplinary frameworks that prioritize patient well-being, fairness, and accountability, while avoiding over-speculation. By integrating cross-study insights, we position governance as integral to AI’s infrastructural role in healthcare, advocating for actionable ethics to bridge regulatory gaps and enhance the reliability of clinical analytics. Ultimately, effective governance will enable AI to converge with human expertise, fostering high-performance medicine without compromising equity or safety.

Federated learning (FL) has emerged as a transformative paradigm in artificial intelligence (AI) for healthcare systems and analytics, enabling collaborative model training across distributed institutions without direct data sharing, thereby addressing stringent privacy regulations such as the Health Insurance Portability and Accountability Act (HIPAA) and General Data Protection Regulation (GDPR). This narrative review synthesizes the architectural models underpinning FL ecosystems in healthcare, elucidating their integration into clinical analytics pipelines and the privacy trade-offs they entail. We delineate how FL facilitates decentralized AI applications in areas such as predictive modeling for clinical outcomes, medical imaging analysis, and real-time health monitoring, while balancing model utility against data protection imperatives.Central to FL architectures are client-server frameworks where edge devices (e.g., hospitals or wearable sensors) perform local training on siloed datasets, aggregating updates via a central coordinator to refine global models. Variants include horizontal FL for identical feature spaces across institutions and vertical FL for complementary datasets, often augmented with differential privacy mechanisms to mitigate inference attacks. In healthcare systems, these models support analytics for disease prediction, as seen in COVID-19 outcome forecasting, and enable scalable infrastructures for multi-institutional collaborations without compromising patient confidentiality. However, privacy trade-offs manifest in reduced model accuracy due to noisy perturbations, communication overheads in bandwidth-constrained environments, and vulnerabilities to model inversion or membership inference attacks.We explore the landscape of AI-driven healthcare systems, highlighting how FL integrates with electronic health records (EHRs), imaging repositories, and wearable data streams to foster intelligent analytics. Key syntheses include closed-loop systems where AI inferences inform clinical decisions, feedback loops recalibrate models, and governance layers ensure ethical deployment. Challenges such as data heterogeneity across federated nodes and the need for robust incentive mechanisms are critically examined, alongside opportunities for hybrid FL-blockchain integrations to enhance trust. This review posits that optimized FL ecosystems can revolutionize healthcare delivery by enabling privacy-preserving, generalizable AI analytics, but that these systems require interdisciplinary frameworks to navigate trade-offs between innovation and patient safeguards. Ultimately, FL represents a cornerstone for sustainable, equitable AI in healthcare, promoting data sovereignty while accelerating clinical insights.

Atrial fibrillation (AFib) is a major and often undiagnosed risk factor for ischemic stroke, with paroxysmal episodes that frequently evade conventional intermittent monitoring. Wearable devices combining photoplethysmography (PPG) and single-lead ECG have enabled large-scale AFib screening, but many current systems rely on cloud-based processing, introducing latency, connectivity dependence, and privacy concerns. While clinical studies demonstrate promising detection performance, real-world deployment remains limited by the lack of fully continuous, autonomous operation. Edge artificial intelligence (AI), which enables on-device deep-learning inference directly on smartwatches, represents a key advancement toward real-time, scalable AFib detection. By eliminating reliance on cloud infrastructure, edge AI reduces latency, enhances privacy, and supports immediate alerts during transient arrhythmic events. However, practical implementation requires careful optimization of model efficiency, power consumption, and hardware constraints alongside clinical validation. Future progress will depend on multi-objective design strategies that integrate accuracy, latency, and energy efficiency, as well as collaboration among engineers, clinicians, and regulators. Addressing challenges such as alert fatigue, equitable access, and data governance will be essential. Ultimately, edge AI has the potential to transform AFib management from reactive diagnosis to continuous, preventive monitoring, functioning as an unobtrusive, always-available cardiac safeguard.

Type 2 diabetes affects over 400 million people worldwide and requires lifelong management through continuous monitoring of laboratory values, medications, and comorbidities, yet the use of longitudinal electronic health records for research is restricted by privacy regulations such as HIPAA and GDPR, making synthetic data generation an important alternative for preserving utility while protecting confidentiality. However, existing synthetic data models often fail to accurately capture temporal treatment effects and the gradual development of comorbidities, limiting their usefulness for downstream clinical and machine learning applications. To address this, a time-series generative adversarial network is proposed for longitudinal diabetes data, incorporating a temporal encoder for irregular sampling, a treatment-conditioned generator, and dual discriminators that evaluate both static patient characteristics and dynamic clinical trajectories to ensure consistency between interventions and outcomes. By explicitly modeling temporal dependencies and comorbidity structures, the framework produces more realistic synthetic patient records that better reflect disease progression and medication-response relationships, thereby enabling privacy-preserving data sharing while supporting robust secondary analyses and future applications in chronic disease modeling.

Cardiovascular disease remains the leading global cause of death, emphasizing the need for improved risk stratification beyond traditional tools such as Framingham, ASCVD, QRISK, and SCORE, which show limitations in diverse modern populations. Machine learning methods applied to electronic health records can enhance prediction by capturing complex, high-dimensional, and nonlinear relationships. This systematic review (2017–2022) evaluated machine learning models for cardiovascular risk prediction using EHR data, focusing on discrimination (AUROC, AUPRC), calibration, external validation, and reporting quality including TRIPOD adherence. A PRISMA-compliant search identified peer-reviewed studies applying machine learning to EHR-based cardiovascular risk prediction. Risk of bias was assessed using PROBAST, and narrative synthesis was conducted due to heterogeneity. Twenty-nine studies were included. XGBoost, random forest, and neural networks were the most common models and generally outperformed logistic regression and traditional risk scores in discrimination. However, calibration was infrequently reported, and external validation was limited, often showing reduced performance. Machine learning models demonstrate improved predictive discrimination over conventional risk scores, but limited calibration assessment and weak external validation constrain clinical applicability. Stronger validation frameworks are needed for clinical translation.

Breast cancer remains a leading cause of cancer-related mortality among women worldwide, underscoring the importance of effective screening strategies for early detection and improved survival. Although conventional modalities such as mammography reduce mortality, they are limited by false positives, false negatives, and overdiagnosis, particularly in dense breast tissue and diverse populations. Deep learning, especially convolutional neural networks (CNNs), has shown promise in improving diagnostic accuracy and reducing inter-reader variability; however, its translation into routine clinical practice requires critical evaluation beyond reported performance metrics. This critical review evaluates CNN-based deep learning applications for breast cancer detection across mammography, ultrasound, and MRI, with emphasis on training strategies and barriers to clinical deployment. A targeted literature search identified peer-reviewed studies focusing on CNN architectures, transfer learning, and implementation challenges. Findings indicate that models such as ResNet, DenseNet, and EfficientNet perform well in controlled settings, supported by transfer learning and data augmentation approaches. However, these results often fail to translate into consistent clinical performance, particularly across imaging modalities and real-world workflows. Limitations including demographic bias, insufficient external validation, and weak evidence of outcome or cost-effectiveness highlight a substantial gap between experimental success and clinical readiness. The review concludes that while deep learning in breast imaging is promising, its adoption should remain cautious and evidence-driven until robust clinical benefit is clearly demonstrated.

Emergency department crowding is a persistent global healthcare challenge linked to longer wait times, increased patients leaving without being seen, worse clinical outcomes, and staff burnout. It also contributes to ambulance diversion and inefficient resource use, worsening hospital operational strain. This systematic review evaluates machine learning models for predicting ED crowding and optimizing patient flow, focusing on input features (e.g., arrival rates, acuity, bed availability) and reported operational outcomes such as waiting times and ambulance delays. A PRISMA-compliant review was conducted across PubMed, Embase, IEEE Xplore, and Scopus. Included studies applied machine learning to ED crowding or patient flow prediction and reported operational or crowding outcomes. Due to heterogeneity, a narrative synthesis was used, and risk of bias was assessed using an adapted tool. Thirty-two studies met inclusion criteria, using classification, regression, time-series, and deep learning models. Common predictors included arrival patterns, occupancy, and bed availability. While predictive performance was generally high, few studies evaluated real-world operational impacts, and most remained retrospective. Although machine learning models demonstrate strong predictive accuracy for ED crowding, evidence of real-world operational benefits remains limited. A clear gap exists between prediction and implementation into clinical workflow and decision-making. Future research should focus on translating predictions into measurable improvements in ED performance.

Mortality prediction in the ICU is essential for effective resource allocation and early clinical intervention. Bedside monitors generate multivariate physiological time-series data, but these are often irregularly sampled, making standard predictive modeling challenging. Conventional transformer models assume regular time intervals and fixed positional encodings, which limits their ability to capture clinically meaningful temporal gaps in real ICU data. This can reduce the accuracy of mortality risk prediction by obscuring important short- and long-term physiological patterns.To address this limitation, the TERTIAN framework introduces a hierarchical transformer with time-aware positional encoding specifically designed for irregular ICU data. It combines a local transformer to capture short-term dynamics and a global transformer to model long-term trends, integrating both through time-sensitive attention mechanisms. This design eliminates the need for data imputation and improves temporal understanding of patient trajectories.Overall, the framework better captures rapid deterioration and gradual decline by respecting irregular sampling patterns, leading to more clinically relevant predictions. By aligning model structure with real-world ICU data characteristics, TERTIAN offers a promising approach for improving mortality prediction and supporting critical care decision-making.

Diabetic retinopathy is a leading cause of preventable blindness, with fundus photography commonly used for early detection and severity grading, while deep learning models have shown strong performance in classification but require large, diverse multi-center datasets that are difficult to obtain due to privacy and regulatory restrictions. Because fundus images are protected health information, hospitals cannot share data, resulting in isolated datasets that limit model generalizability across different populations, imaging devices, and clinical settings. To overcome this limitation, a hybrid framework combining federated learning with homomorphic encryption is proposed, allowing multiple hospitals to collaboratively train a shared model without exchanging raw images or plaintext gradients. Each institution performs local training and transmits only encrypted model updates to a central server for secure aggregation, ensuring that patient data remains fully protected while still enabling global model improvement. This approach also mitigates gradient leakage and reconstruction attacks, supports compliance with regulations such as HIPAA and GDPR, and enables scalable, fault-tolerant deployment across heterogeneous healthcare systems, ultimately providing a privacy-preserving pathway for robust multi-center diabetic retinopathy detection.

Rare dermatological conditions (or orphan diseases) present major diagnostic challenges due to their low prevalence, limited clinician exposure, and the scarcity of well-labeled datasets, which together hinder the development of conventional AI systems. As a result, most deep learning models trained on supervised approaches perform well only on common skin diseases while failing to generalize to rare conditions, leaving a significant gap in clinical support and contributing to delayed diagnoses and worse patient outcomes, especially in regions with limited specialist access. To address this limitation, contrastive language-image pre-training offers a promising alternative by leveraging paired dermatological images and unstructured clinical notes from electronic health records in a self-supervised manner. This allows models to learn meaningful visual–textual relationships without requiring large-scale manual annotation. The framework typically includes an image encoder, a clinical text encoder, a contrastive alignment objective, and a zero-shot classification mechanism based on prompt similarity. By learning from existing multimodal clinical data, such systems can generalize to previously unseen rare conditions and enable zero-shot diagnosis, reducing dependence on labeled datasets. This approach transforms routine physician documentation into a rich supervisory signal, helping overcome annotation bottlenecks and improving AI applicability in real-world dermatology settings. Ultimately, foundation models trained in this way offer a scalable path toward more inclusive and effective AI-assisted diagnosis of rare skin diseases.

Chronic kidney disease (CKD) affects 10–15% of adults worldwide and often progresses silently toward kidney failure requiring dialysis or transplantation. Monitoring longitudinal markers such as estimated glomerular filtration rate, creatinine, and albuminuria is essential for early intervention and delaying disease progression. However, current predictive models typically rely on static or isolated clinical features, limiting their ability to capture dynamic interactions between laboratory trends, medications, and comorbidities, which leads to incomplete risk assessment. To address this limitation, a conceptual framework based on a graph convolutional network with attention mechanisms is proposed to integrate longitudinal laboratory data, medication networks, and comorbidity structures for CKD progression prediction. Patient records from 2017–2023 are represented as a heterogeneous graph, where nodes include laboratory values, drugs, and diagnoses, and edges encode clinical and pharmacological relationships. Graph convolutional layers capture relational patterns, while attention mechanisms highlight the most clinically relevant interactions, enabling more informative patient-level representations for risk prediction across CKD stages. This approach improves interpretability by revealing which laboratory trends, medications, and comorbidities most influence predicted outcomes, aligning model behavior with clinical nephrology knowledge. Overall, the framework provides a unified and scalable strategy for more accurate and interpretable CKD progression risk prediction by leveraging relational and temporal data structures that traditional models fail to exploit.

Hospital-acquired pressure injuries (HAPIs) are a common and largely preventable complication in ICU patients, affecting 5–15% of cases and contributing to increased morbidity and healthcare costs. Despite standardized nursing protocols, incidence remains high, highlighting the need for more effective predictive and preventive approaches. While traditional tools like the Braden Scale offer interpretability, they lack sufficient predictive accuracy in critically ill populations. In contrast, machine learning models such as XGBoost and random forests improve prediction but function as black boxes, limiting clinical trust and actionable insight. To address this gap, this work proposes an Explainable Boosting Machine (EBM) framework trained on electronic health record (EHR) data from over 50,000 ICU admissions (2017–2023). EBMs combine strong predictive performance with interpretability by modeling feature effects through shape functions and capturing pairwise interactions. This allows identification of both global and patient-specific risk factors while maintaining transparency. The framework emphasizes modifiable factors such as repositioning frequency, nutrition, and medical device management, revealing nonlinear thresholds and interaction effects often missed by conventional methods. Overall, the proposed approach integrates accurate prediction with clear, clinically interpretable insights, enabling real-time identification of actionable risk factors for HAPI prevention. By bridging predictive modeling and nursing decision-making, it supports more targeted interventions and improved patient outcomes in critical care settings.

Sepsis prediction models perform poorly when transferred between ICUs due to demographic and practice variation, leading to substantial performance drops caused by differences in patient populations, admission criteria, and data recording standards, which limits reliable deployment across healthcare systems. Retraining models from scratch requires large labeled datasets that many ICUs lack due to cost, time, and resource limitations, making it difficult for low-resource settings to develop or adopt effective predictive tools. We propose a meta-learning approach that enables rapid adaptation of sepsis prediction models using few-shot local data, leveraging pre-training across multiple ICUs to support fast personalization in new environments. The framework includes meta-training across diverse source ICUs to learn a generalizable initialization and meta-adaptation at the target ICU using only a few gradient updates on limited data, enabling efficient few-shot learning. This approach improves sepsis prediction in low-resource and heterogeneous ICU settings by reducing data requirements and increasing robustness to demographic shifts, supporting more equitable access to AI tools in critical care. The proposed framework enables efficient and fair deployment of sepsis prediction models across diverse ICUs, bridging resource gaps and improving scalability and adaptability of clinical AI systems globally.

Elevated intracranial pressure (ICP) is a critical condition in traumatic brain injury, stroke, intracerebral hemorrhage, and hydrocephalus, often associated with poor outcomes when exceeding 20–25 mmHg. While invasive monitoring is accurate, it carries risks and is not always feasible, motivating the use of non-invasive approaches based on transcranial Doppler (TCD) ultrasound and arterial blood pressure (ABP) waveforms for continuous neurocritical care monitoring. However, existing non-invasive methods and purely data-driven machine learning models often lack physiological grounding, leading to reduced reliability and potential violations of cerebral hemodynamic principles, especially across diverse ICU settings with variable signal quality. To address these limitations, a physics-informed neural network (PINN) framework is proposed that integrates TCD and ABP signals while embedding cerebral hemodynamic equations into the learning process. The model uses separate encoders for TCD and ABP features, followed by a physics-constrained module and a loss function combining data accuracy with physical law consistency, such as mass conservation and pressure–flow relationships. This structure enables physiologically consistent ICP estimation, reduces data requirements, and improves generalization in clinical environments where labeled data are limited. Overall, the PINN-based approach enables more reliable, non-invasive, and continuous ICP monitoring by combining machine learning with physiological modeling. It offers a safer alternative when invasive monitoring is not possible and supports improved clinical decision-making in neurocritical care, though challenges remain in modeling complex autoregulation and ensuring high-quality waveform inputs.
