Despite these advances, healthcare organizations continue to face challenges related to digital literacy, uneven access to technology, data privacy, platform interoperability, and the integration of advanced digital solutions into clinical and operational workflows. This paper proposes an analytics-driven telemedicine framework that emphasizes secure data governance, interoperability, and decision support in healthcare organizations. The framework integrates permissioned blockchain services to provide immutable logging, identity and access management, and end-to-end traceability of clinical and pharmaceutical activities, while federated learning supports decentralized model training without centralizing sensitive patient data. In addition, large language models are incorporated to enhance clinical text understanding and enable multimodal decision making. The framework is evaluated through controlled experiments across two complementary dimensions. An operational simulation of healthcare service indicators demonstrates meaningful performance gains under controlled conditions, reducing consultation response times from 24 to 72 h to 1 to 4 h, shortening diagnostic delays from 3 to 7 days to 2 to 12 h, and decreasing medication traceability errors from 2 to 8 percent annually to below 0.5 percent. A multimodal analytics assessment using 15,000 paired medical images and clinical reports related to breast, liver, and lung cancer shows strong predictive performance, with the best configuration achieving 93.5% accuracy, 94.5% precision, and 91.5% recall, along with low cross entropy values that indicate reliable classification and coherent report generation. Overall, the results indicate that the integration of advanced analytics with secure and auditable data infrastructure can improve efficiency, data integrity, and clinical decision support in telemedicine systems. The framework is particularly relevant for healthcare environments where institutional fragmentation and infrastructure limitations require scalable, privacy-preserving, and interoperable digital solutions.</div></div>","PeriodicalId":73222,"journal":{"name":"Healthcare analytics (New York, N.Y.)","volume":"9 ","pages":"Article 100472"},"PeriodicalIF":0.0,"publicationDate":"2026-06-01","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"148183850","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":0,"RegionCategory":"","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}

While traditional methods often focus on univariate time series and assume fixed temporal dynamics, real-world systems are typically multivariate and characterized by complex interdependencies. Ignoring these relationships can lead to suboptimal detection of system-level anomalies. This paper proposes a novel graph-based framework for multivariate time series anomaly detection that explicitly captures temporal patterns and structural relationships among variables. Individual univariate time series are first transformed into Horizontal Visibility Graphs (HVGs), which are then combined into multiplex networks to preserve inter-layer interactions. Additionally, we construct feature-based similarity graphs derived from statistical properties of the series to model inter-series relations. Anomalies are identified by comparing the neighborhood structure of each series against a historical reference set, enabling the detection of subtle and coordinated deviations. Computational experiments on real-world healthcare data illustrate the behavior and practical relevance of the proposed approach in capturing complex anomalies, offering a robust and interpretable alternative to traditional techniques.</div></div>","PeriodicalId":73222,"journal":{"name":"Healthcare analytics (New York, N.Y.)","volume":"9 ","pages":"Article 100447"},"PeriodicalIF":0.0,"publicationDate":"2026-06-01","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"146023162","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":0,"RegionCategory":"","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}

This coupling of tumor-immune-drug interactions, calibrated specifically for breast cancer, distinguishes the model from existing mathematical tumor-immune systems. To maintain simplicity and avoid unnecessary complexity, the study initially considers the interaction between tumor cells and the two cytokine groups. The results show that cytokines alone are insufficient to eliminate tumor cells. The analysis then extends to the interaction between tumor cells and the three immune cell types. Graphical simulations demonstrate that tumor cells can still evade immune cell responses. A dynamical analysis is conducted, proving the uniqueness and nonnegativity of the model solutions and identifying two types of equilibrium points. The existence conditions for each equilibrium are discussed. A transcritical bifurcation analysis (TBA) indicates that the tumor-free equilibrium loses stability at a critical tumor growth rate of 0.25 per day, beyond which a stable positive tumor state emerges. Comparison with clinical tumor growth data shows that the model accurately captures tumor dynamics, achieving a goodness-of-fit of 98.46 percent using nonlinear least squares (NLS) fitting. The full model, which incorporates immune cells, tumor cells, and a chemotherapeutic agent, is then presented. Mathematical techniques are applied to reduce the system, and the Adomian Decomposition Method (ADM) is used for analysis. The convergence of ADM in the context of the model is established and proved. Graphical results indicate that tumor cells can be eliminated under this treatment strategy. Phase-plane (PP) and vector field (VF) analyses reveal oscillatory immune responses and regulatory feedback among immune cells, while surface plots highlight the sensitivity of tumor suppression to key parameters. The findings suggest that effective treatment requires both reducing tumor proliferation and enhancing immune-mediated lysis.

A retrospective cohort of 6661 inpatient admissions from an academic hospital was analyzed, with 1.8% experiencing at least one fall. In line with recent guideline recommendations that discourage the use of stand-alone fall risk scores for screening, this work uses routinely collected electronic health record (EHR) data to support locally defined multifactorial fall prevention rather than proposing a new point-of-care score. The selected SEIPS-based Autoencoder, evaluated under nested stratified cross-validation, showed more balanced performance than purely data-driven models and achieved a recall of 0.74 for fall events. Feature analysis identified clinically plausible contributors spanning patients, tasks, tools, and technology, organizational conditions, and physical environment. BBNs captured probabilistic dependencies among these predictors, and CEGs summarized high-risk pathways involving combinations of impaired mobility, lower cognitive status, intermediate neurological responsiveness, and higher potassium values. Uplift modeling suggested that patients who received fall education had an estimated 7.5% lower probability of falling, under standard causal assumptions for observational data.

Unlike conventional models that rely solely on deterministic parameters, the incorporation of fuzzy theory allows for representing uncertainties and variabilities inherent in real-world disease transmission. The model further incorporates time-delay terms to account for incubation periods and other latent effects, enhancing the accuracy of system dynamics. This fuzzy framework performs key analyses, including identifying equilibrium points, computation of the basic reproduction number, sensitivity analysis, and assessment of local and global stability. Numerical solutions are obtained using the Forward Euler and Nonstandard Finite Difference (NSFD) methods. The NSFD scheme is rigorously examined for convergence, non-negativity, boundedness, and consistency properties. Simulation results confirm that the NSFD approach maintains the qualitative features of the model even under larger time steps.
