Contemporary healthcare delivery is characterized by frequent deviations from normative care pathways, driven by patient heterogeneity, resource variability, and real-time clinical judgment. Rather than viewing these deviations as noise to be minimized, the present conceptual work reframes them as structured knowledge artifacts amenable to systematic interpretation. We propose a sequence pattern language that encodes deviations as first-class clinical signals within AI-enabled healthcare analytics infrastructures. Building on established process-mining foundations and EHR intelligence ecosystems, the language formalizes deviation sequences into interpretable knowledge structures that can inform decision support pipelines without requiring empirical model training or performance benchmarking.

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.
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.
