Latest 84 papers on healthcare: Feb. 21, 2026

Artificial intelligence is rapidly transforming healthcare, moving beyond theoretical discussions to deliver tangible solutions in diagnostics, treatment optimization, and patient engagement. Recent advancements highlight a multifaceted approach, leveraging sophisticated models, robust evaluation frameworks, and ethical considerations to address some of the most pressing challenges in clinical practice. From enhancing diagnostic accuracy to ensuring data privacy and promoting equitable care, AI and ML are poised to redefine the patient-physician relationship and democratize access to high-quality healthcare.

The Big Idea(s) & Core Innovations

At the heart of these breakthroughs is the pursuit of more reliable, accessible, and ethical AI in healthcare. One prominent theme is the use of federated and hybrid learning to ensure data privacy without compromising model performance. Chowdhury et al. (from unspecified affiliations), in their paper “A Hybrid Federated Learning Based Ensemble Approach for Lung Disease Diagnosis Leveraging Fusion of SWIN Transformer and CNN”, propose fusing SWIN Transformers and CNNs within a federated learning (FL) framework to boost lung disease diagnostic accuracy while keeping sensitive patient data localized. Building on this, “Hybrid Federated and Split Learning for Privacy Preserving Clinical Prediction and Treatment Optimization” by Author Name 1 and Author Name 2 introduces a hybrid FL and Split Learning (SL) model, demonstrating superior performance and privacy compared to standalone methods. Similarly, Irureta et al. (from Ikerlan Technology Research Center and others) in “Mixture of Predefined Experts: Maximizing Data Usage on Vertical Federated Learning” present Split-MoPE, an alignment-agnostic Vertical Federated Learning (VFL) framework that is robust against data misalignment and malicious participants.

Large Language Models (LLMs) are also being tailored for complex clinical tasks. Karacan et al. (University of Illinois Chicago), in “Bridging the Domain Divide: Supervised vs. Zero-Shot Clinical Section Segmentation from MIMIC-III to Obstetrics”, explore the adaptability of zero-shot LLMs for clinical section segmentation, finding that post-processing corrections can overcome domain adaptation challenges. Ferrazzi et al. (Fondazione Bruno Kessler and University of Padova) show in “Small LLMs for Medical NLP: a Systematic Analysis of Few-Shot, Constraint Decoding, Fine-Tuning and Continual Pre-Training in Italian” that fine-tuning small LLMs can achieve performance comparable to or even surpassing larger models for Italian medical NLP tasks. For Alzheimer’s disease diagnosis, Zhang et al. (University of Toronto, Harvard Medical School, and others) explore “Chain-of-Thought Reasoning with Large Language Models for Clinical Alzheimer’s Disease Assessment and Diagnosis”, demonstrating enhanced diagnostic accuracy through structured reasoning pathways.

Addressing biases and enhancing fairness is another critical area. Shabu et al. (University of Sheffield and University of Chester) in “A Generative AI Approach for Reducing Skin Tone Bias in Skin Cancer Classification” use generative AI (Stable Diffusion with LoRA fine-tuning) to augment datasets and reduce skin tone bias in skin cancer detection. Hirsch et al. (Instituto de Ciencias de la Computación and others) highlight in “Implicit Bias in LLMs for Transgender Populations” the persistent implicit biases in LLMs regarding transgender individuals in healthcare scenarios, underscoring the need for more equitable AI systems. The MENTAT dataset, introduced by Lamparth et al. (Stanford University and others) in “Moving Beyond Medical Exams: A Clinician-Annotated Fairness Dataset of Real-World Tasks and Ambiguity in Mental Healthcare”, aims to evaluate language models on real-world mental health tasks with explicit demographic bias removal.

Beyond individual models, robust evaluation and integration frameworks are emerging. “A Scalable Framework for Evaluating Health Language Models” by Mallinar et al. (Google Research and Vituity) introduces Adaptive Precise Boolean rubrics, significantly improving inter-rater reliability and efficiency in evaluating health LLMs. Boll et al. (Amsterdam UMC, University of Amsterdam, and University of São Paulo) offer “DistillNote: Toward a Functional Evaluation Framework of LLM-Generated Clinical Note Summaries”, focusing on retaining diagnostic utility in compressed clinical summaries. For more reliable conversational agents, Silva et al. (Sword Health) introduce “Arbor: A Framework for Reliable Navigation of Critical Conversation Flows” to decompose decision tree navigation into node-level tasks, enhancing accuracy and efficiency in healthcare triage.

Remote healthcare and infrastructure are also seeing significant advancements. Kumar et al. (University of Surrey) address “Hierarchical Edge-Cloud Task Offloading in NTN for Remote Healthcare” through a hierarchical edge-cloud framework for Non-Terrestrial Networks (NTN), optimizing latency and QoS. Monfared et al. (University of Bergamo and University of Jyväskylä) explore the integration of “Quantum Computing for Healthcare Digital Twin Systems”, identifying challenges and directions for secure, clinically viable Quantum Digital Twins (QDTs). Pei et al. (TU Dortmund University) propose “A Real-Time DDS-Based Chest X-Ray Decision Support System for Resource-Constrained Clinics” using FastDDS middleware and ResNet50 for efficient, low-latency diagnostic support.

Ethical considerations are being proactively integrated into AI design. Ranischa and Salloch (University of Potsdam and Hannover Medical School) discuss in “Agentic AI, Medical Morality, and the Transformation of the Patient-Physician Relationship” how autonomous AI could reshape medical morality and the patient-physician dynamic, calling for ethical foresight. Jerry et al. (Universidad Carlos III de Madrid) propose “Human Oversight-by-Design for Accessible Generative IUIs”, a framework for embedding human oversight into generative AI interfaces for high-stakes domains like healthcare, ensuring traceability and accountability.

Impact & The Road Ahead

These advancements collectively paint a picture of a healthcare future where AI is not just a tool but a trusted partner. The development of privacy-preserving techniques like federated and split learning is crucial for building trust in AI systems that handle sensitive patient data. The increasing sophistication of LLMs in clinical NLP, from section segmentation to diagnostic reasoning, promises to alleviate administrative burdens and provide clinicians with richer, more accessible information. However, the explicit focus on fairness and bias mitigation in model training and evaluation, particularly for underrepresented populations, underscores the critical need for ethical AI development.

The creation of specialized datasets and benchmarks, like MENTAT, ADRD-Bench, and 3DLAND, is instrumental in pushing the boundaries of what AI can achieve in specific medical domains. These resources enable researchers to develop and rigorously test models for real-world applicability, moving beyond theoretical performance to practical utility. Furthermore, frameworks for efficient model selection, interpretable explanations, and human oversight are vital for integrating AI safely and effectively into clinical workflows. Innovations in remote healthcare, such as edge-cloud offloading and quantum digital twins, will expand access to quality care, especially in underserved areas, by addressing latency and scalability issues.

The ethical discussions around agentic AI and its impact on the patient-physician relationship are paramount. As AI systems become more autonomous, proactive design that incorporates human values, ethical foresight, and robust governance will be essential. The roadmap ahead involves continuous innovation in model trustworthiness, fairness, and interpretability, alongside the development of adaptable, culturally competent AI solutions. Ultimately, these advancements are paving the way for a more intelligent, equitable, and patient-centered healthcare ecosystem, where AI supports both clinical excellence and human well-being.
