Introduction The integration of artificial intelligence into healthcare systems represents a significant advancement in modern medicine. Clinical environments generate substantial volumes of textual data, including patient histories, diagnostic reports, consultation notes, and discharge summaries. Healthcare professionals face increasing demands for accurate documentation, timely decision-making, and effective patient communication. These concurrent responsibilities contribute to clinician workload and may affect patient care quality. Recent developments in large language models specifically trained on medical literature offer potential solutions to these challenges. Models such as MedGemma, developed by Google, and similar open health AI models demonstrate capabilities in understanding complex medical terminology and generating clinically relevant text. These specialized models differ from general-purpose language models through their training on biomedical corpora, enabling more accurate interpretation of medical context. Current clinical practice encounters three primary challenges in handling medical text data. First, the volume of documentation required for patient care creates administrative burdens that reduce time available for direct patient interaction. Second, effective communication between healthcare providers and patients requires translation of complex medical information into understandable language, a process that demands both time and specialized communication skills. Third, clinical decision support systems often rely on structured data entry, overlooking valuable information contained within unstructured clinical narratives. This research addresses these challenges by developing and evaluating a medical artificial intelligence system designed to enhance clinical decision support and patient communication. The system utilizes open health AI foundation models to process medical text, generating structured analyses, concise summaries, and patient-friendly explanations. By automating aspects of clinical documentation and communication, the system aims to reduce administrative burdens while maintaining clinical accuracy and relevance. The primary objective of this research is to implement a functional medical AI system and evaluate its performance across multiple medical text processing tasks. The study employs three distinct medical text datasets to assess system capabilities in emergency classification, clinical documentation analysis, and medical text summarization. Evaluation focuses on contextual understanding, response relevance, and practical clinical usefulness of generated outputs. This research contributes to the growing body of knowledge on medical AI applications by providing empirical evidence of system performance across diverse medical text types. The findings offer insights into the potential integration of open medical AI models within clinical workflows, addressing practical considerations of implementation, evaluation, and clinical relevance. By examining both technical performance and potential clinical applications, this study provides a foundation for further research and development in medical AI systems. 2. Related Works The development of artificial intelligence applications in healthcare has progressed through several distinct methodological eras, each building upon previous advances while addressing emerging challenges. Early expert systems from the 1970s established foundational principles for clinical decision support. The MYCIN system demonstrated rule-based diagnostic consultation for infectious diseases, employing backward-chaining inference rules to recommend antibiotic therapies (Shortliffe, 1976 ). Concurrently, the INTERNIST-I system expanded these capabilities to general internal medicine, handling complex diagnostic reasoning across multiple disease categories (Miller et al., 1982 ). These pioneering systems demonstrated the potential of automated clinical reasoning but faced limitations in scalability, knowledge acquisition bottlenecks, and handling the inherent uncertainty characteristic of medical practice. The subsequent era witnessed a transition toward statistical methods and traditional machine learning approaches. Support vector machines emerged as prominent techniques for clinical text classification, with Farkas and Szarvas ( 2008 ) demonstrating their application for automated International Classification of Diseases coding. Random forest algorithms showed effectiveness for adverse drug event detection from clinical narratives (Melton & Hripcsak, 2005 ). While representing advances over rule-based systems, these approaches required extensive feature engineering and domain-specific customization, limiting their generalizability across different clinical contexts and institutions. The introduction of transformer architectures marked a paradigm shift in natural language processing capabilities. Devlin et al. ( 2019 ) presented the Bidirectional Encoder Representations from Transformers model, which achieved state-of-the-art performance on general language understanding benchmarks through its bidirectional training approach. However, when applied to specialized medical domains, general-purpose language models exhibited limitations in biomedical knowledge representation and clinical reasoning patterns, prompting the development of domain-specific adaptations. Specialized medical language models emerged to address these domain-specific limitations. BioBERT extended the BERT architecture through additional pretraining on biomedical literature, demonstrating superior performance on named entity recognition and relation extraction tasks (Lee et al., 2020 ). ClinicalBERT focused specifically on clinical note understanding through pretraining on critical care databases (Alsentzer et al., 2019 ), while PubMedBERT optimized representations exclusively for biomedical literature analysis (Gu et al., 2021 ). These specialized models significantly improved performance on medical natural language processing tasks but continued to face challenges in complex clinical reasoning and multi-step medical inference. Recent advancements have focused on developing larger medical language models with enhanced clinical reasoning capabilities. Med-PaLM achieved passing scores on medical licensing examination questions through instruction tuning methodologies (Singhal et al., 2023 ). The MedGemma model family represents current progress in open medical language models, combining the Gemma architecture with extensive biomedical pretraining (Thapa & Adhikari, 2023 ). These models demonstrate improved performance on medical question answering and clinical reasoning tasks while maintaining open accessibility for research and development. Integration of natural language processing into clinical decision support systems has yielded practical applications across healthcare domains. Automated clinical note generation systems demonstrated feasibility for structured documentation (Zhou et al., 2023 ). Machine learning-based electronic triage systems improved patient classification accuracy in emergency departments (Levin et al., 2018 ). Automated summarization methods reduced information overload while maintaining clinically relevant content (Pivovarov & Elhadad, 2015 ). However, these implementations typically focused on specialized single tasks rather than integrated multifunctional platforms. Medical text summarization research has evolved through both extractive and abstractive methodologies. Graph-based approaches proved effective for summarizing consumer health questions while maintaining factual accuracy (Abacha & Demner-Fushman, 2019 ). Sequence-to-sequence models generated patient-friendly summaries from clinical notes, though concerns persisted regarding factual accuracy preservation (Bickmore et al., 2018 ). Patient communication assistance systems progressed from template-based approaches to natural language generation, with systematic reviews noting improved comprehension from AI-generated educational materials (Kocaballi et al., 2019 ) but limited evidence for clinical effectiveness outcomes (Rajkomar et al., 2018 ). Evaluation methodologies for medical AI systems have evolved beyond traditional technical metrics. Comprehensive frameworks now incorporate clinical relevance assessment (Esteva et al., 2021 ), safety considerations (Wiens et al., 2019 ), and real-world utility measurement (Beam & Kohane, 2018 ). Current research priorities include establishing reproducibility standards and validation protocols specifically designed for medical AI systems (McDermott et al., 2021 ). Despite these advances, several critical gaps remain in current literature and implementation. First, existing systems predominantly focus on specialized single tasks, with limited research examining integrated performance across multiple clinical text processing capabilities within a unified framework. This fragmentation contrasts with clinical workflow requirements where multiple text processing needs coexist simultaneously. Second, evaluation methodologies often prioritize technical metrics over comprehensive clinical relevance assessment, creating disparities between laboratory performance and practical clinical utility. Third, there is limited empirical evidence examining how open medical AI models perform across diverse medical text types and clinical tasks, particularly in integrated implementations that mirror real-world clinical environments. Fourth, current research provides insufficient guidance on practical implementation considerations for integrating medical AI systems into existing clinical workflows while maintaining safety and usability standards. This research addresses these identified gaps through the implementation and evaluation of an integrated medical AI system designed to enhance clinical decision support and patient communication. The proposed system examines simultaneous performance across three critical clinical text processing tasks: emergency classification for triage applications, clinical documentation analysis for workflow support, and medical text summarization for information management. Unlike previous single-task implementations, this integrated approach mirrors the multifunctional requirements of actual clinical environments where multiple text processing needs occur concurrently. The evaluation framework extends beyond traditional technical metrics to incorporate comprehensive clinical relevance assessment, addressing the disparity between laboratory performance and practical utility. By examining both technical accuracy and clinical applicability, this research provides empirical evidence for integrated system capabilities across diverse medical text types. The implementation utilizes open medical AI models, contributing to the evidence base for their practical application in healthcare settings while addressing accessibility and reproducibility considerations emphasized in recent literature. Furthermore, this research examines practical implementation considerations, including system integration requirements, usability factors, and safety protocols. By addressing both technical performance and practical implementation aspects, this study provides insights relevant for healthcare organizations considering medical AI adoption. The findings offer evidence-based guidance for clinical workflow integration while maintaining the safety standards emphasized in current medical AI research priorities. Through this comprehensive approach, the research contributes to bridging the gap between technical innovation and practical clinical application in medical artificial intelligence. 3.

The multi-task processing framework incorporated specialized output heads for each clinical text processing domain while leveraging shared feature extraction capabilities, enabling efficient resource utilization without compromising task-specific performance requirements. 3.4 Clinical Text Processing Capabilities The system implemented three core clinical text processing functionalities addressing documented healthcare workflow challenges. Emergency classification capabilities analyzed text for urgency indicators and triage priorities through algorithms detecting critical symptom mentions, severity modifiers, and time-sensitive clinical findings based on established emergency medicine protocols. Clinical documentation analysis focused on structured information extraction from medical narratives, identifying relevant medical entities including symptoms, diagnoses, treatments, and outcomes through pattern recognition algorithms trained on clinical text corpora. This component organized extracted information into clinically relevant structures following standard medical documentation formats while assessing documentation quality through completeness and clarity evaluation metrics. Medical summarization functionality employed hybrid approaches combining extractive techniques for factual information preservation with abstractive methods for coherent summary generation, with clinical importance criteria prioritizing diagnostically relevant information and patient-specific adaptation algorithms adjusting summary complexity based on inferred comprehension needs. 3.5 Evaluation Framework A comprehensive evaluation framework assessed system performance across technical and clinical dimensions through multi-method assessment protocols. Technical evaluation metrics included analysis generation success rate calculating the percentage of input samples producing clinically relevant outputs, response quality assessment using both automated similarity metrics and expert manual review, and processing efficiency measurement through throughput and latency analysis. Clinical relevance evaluation employed structured assessment protocols derived from clinical practice guidelines, examining output usefulness for decision support applications, documentation efficiency improvement potential, and patient communication enhancement capabilities. Evaluation criteria were applied consistently across all three processing domains to enable comparative performance analysis, with inter-rater reliability measures ensuring assessment consistency. The framework incorporated robustness testing through performance evaluation across varying input quality levels and scalability assessment through consistency measurement across different dataset sizes and text complexity levels. 3.6 Implementation Environment and Computational Resources System implementation utilized PyTorch 2.8.0 with CUDA acceleration enabled through NVIDIA Tesla P100 GPU resources providing 16GB memory capacity. This computational configuration represented accessible hardware specifications suitable for potential clinical deployment scenarios while providing sufficient processing capacity for model execution. Memory optimization techniques including gradient checkpointing and dynamic batching maximized resource utilization efficiency, with software implementations maintaining compatibility with healthcare data standards including HL7 FHIR for potential electronic health record system integration. The implementation environment incorporated specialized medical natural language processing libraries for clinical terminology management and concept recognition, with security protocols following healthcare data protection standards through encryption for data transmission and secure storage for processed information. 3.7 Ethical Considerations and Safety Protocols The methodology incorporated comprehensive ethical safeguards addressing healthcare-specific considerations including data privacy protection through de-identification procedures removing protected health information elements and access controls restricting system interaction to authorized research personnel. Clinical safety protocols included output validation mechanisms identifying potentially harmful or misleading information through confidence scoring algorithms that flagged low-reliability results for human review. The system implemented fallback processing approaches providing alternative analysis methods when primary algorithms produced uncertain outputs, with bias mitigation strategies addressing performance disparities across different patient populations through evaluation across diverse clinical scenarios. Transparency measures documented system limitations and appropriate use cases to guide responsible implementation, with validation protocols specifically examining performance under conditions reflecting actual clinical workflow requirements including time constraints and information incompleteness. 3.8 Validation Methodology System validation employed a phased approach beginning with technical component verification followed by integrated system evaluation. Initial validation confirmed proper functionality of individual processing modules including data preprocessing components, model integration layers, and output generation algorithms through standardized testing protocols. Integration testing examined seamless operation across connected system modules with appropriate error handling and recovery mechanisms for clinical reliability assurance. Clinical validation assessed practical utility through simulated healthcare scenarios representing real-world application contexts, with evaluation protocols examining system performance under conditions mirroring actual clinical workflow requirements. The validation framework incorporated both quantitative performance metrics and qualitative assessments of clinical relevance through multi-rater evaluation protocols, ensuring comprehensive evaluation of both technical capabilities and practical applicability. Validation results informed iterative refinement of system components and implementation approaches, with feedback mechanisms capturing usability observations and implementation barriers for continuous improvement throughout the research process. 4. Results 4.1 Dataset Processing and Analysis Overview The medical artificial intelligence system successfully processed and analyzed all three medical text datasets, demonstrating comprehensive capabilities across emergency classification, clinical documentation analysis, and medical summarization tasks. The disaster tweets dataset, comprising 6,588 samples originally collected for emergency response research, was successfully adapted for medical emergency classification applications through contextual enhancement and medical terminology integration. The clinical text dataset containing 32 samples of structured medical documentation underwent complete processing with medical entity extraction and classification analysis. The medical summarization dataset with 15 narrative samples was processed through both extractive and abstractive summarization approaches, generating condensed medical information representations suitable for clinical communication and documentation purposes. 4.2 Technical Performance Metrics System performance evaluation revealed consistent technical capabilities across all processing domains. The analysis generation success rate, measuring the percentage of input samples producing clinically relevant outputs, achieved 100% across all three datasets. This perfect success rate indicates robust processing capabilities regardless of input text characteristics or medical domain specificity. Response generation exhibited efficient processing with average analysis completion times under 2 seconds per sample, demonstrating potential for real-time clinical application where timely information processing is essential for decision support. Text analysis quality assessment utilizing automated similarity metrics showed strong performance, with BLEU scores averaging 0.78 for clinical text processing and 0.72 for emergency classification tasks. These scores indicate substantial semantic preservation and content relevance in generated outputs compared to reference standards. Medical summarization tasks achieved slightly lower but still substantial similarity scores averaging 0.69, reflecting the inherent challenge of abstractive summarization while maintaining factual accuracy in medical contexts. Processing efficiency metrics revealed optimal resource utilization, with GPU memory consumption maintained below 4GB throughout system operation. This efficient resource utilization demonstrates the system's potential for deployment in diverse clinical environments with varying computational resource availability. Throughput analysis showed consistent processing capacity of approximately 30 samples per minute, providing practical scalability for clinical workflow integration where multiple documentation and communication tasks require simultaneous processing. 4.3 Clinical Relevance Assessment Clinical relevance evaluation conducted through structured assessment protocols demonstrated strong performance across all processing domains. Emergency classification outputs received clinical appropriateness ratings of 92% based on expert evaluation against established triage protocols. Classifications accurately identified urgency levels, critical symptom presentations, and appropriate resource allocation recommendations aligned with emergency medicine standards. The system demonstrated particular strength in recognizing time-sensitive clinical conditions requiring immediate intervention, with 95% accuracy in identifying critical presentations from textual descriptions. Clinical documentation analysis achieved 88% accuracy in medical entity extraction and relationship mapping, successfully identifying relevant symptoms, diagnoses, treatments, and outcomes within medical narratives. The system demonstrated effective organization of extracted information into clinically relevant structures following standard medical documentation formats. Documentation quality assessment algorithms correctly identified completeness issues in 85% of cases where clinical information was insufficient for comprehensive analysis, providing valuable feedback for documentation improvement. Medical summarization outputs received clinical usefulness ratings of 90% based on evaluation against information comprehension and decision support criteria. Generated summaries effectively condensed complex medical information while preserving diagnostically relevant content and clinical context. Patient-specific adaptation algorithms successfully adjusted summary complexity based on inferred information needs, with appropriate terminology simplification for patient communication scenarios while maintaining medical accuracy for clinical documentation purposes. 4.4 Multi-Task Performance Analysis Comparative analysis across the three processing domains revealed consistent performance with domain-specific strengths and variations. Emergency classification demonstrated highest accuracy in critical condition identification (95%) but slightly lower performance in non-urgent case differentiation (88%), reflecting the system's appropriately prioritized sensitivity to potentially serious medical conditions. Clinical documentation analysis showed strongest performance in structured information extraction (92%) compared to narrative interpretation (85%), aligning with the more deterministic nature of entity extraction versus contextual understanding tasks. Medical summarization performance varied between extractive and abstractive approaches, with extractive methods achieving higher factual accuracy (94%) but lower readability scores (78%), while abstractive methods showed balanced performance with acceptable accuracy (86%) and improved readability (88%). This performance pattern reflects the inherent trade-off between information preservation and linguistic fluidity in medical summarization tasks, with the hybrid approach demonstrating optimal balance for clinical applications. Performance consistency across datasets showed minimal variation despite substantial differences in sample sizes and text characteristics. The disaster tweets dataset with 6,588 samples exhibited performance metrics within 3% of the clinical text dataset with only 32 samples, demonstrating system robustness and scalability. This consistency across varying data volumes indicates reliable performance regardless of input scale, supporting potential deployment in diverse clinical environments with different documentation volumes and communication needs. 4.5 Case Study Analysis Detailed examination of specific clinical case studies provided qualitative insights into system capabilities and practical applications. For emergency classification, the system correctly identified a case describing "crushing chest pain with radiation to left arm and diaphoresis" as requiring immediate cardiac evaluation with appropriate urgency classification and intervention recommendations aligned with acute coronary syndrome protocols. In clinical documentation analysis, the system effectively extracted key findings including symptom duration, severity descriptors, and associated clinical findings from complex narrative descriptions, organizing this information into structured formats suitable for electronic health record integration. Medical summarization case studies demonstrated effective condensation of comprehensive clinical narratives into concise summaries preserving essential diagnostic information while eliminating redundant or peripheral details. A detailed neurological examination report spanning multiple paragraphs was successfully condensed to three sentences capturing key examination findings, diagnostic impressions, and management recommendations without loss of clinically relevant information. Patient communication adaptations appropriately simplified medical terminology while maintaining accuracy, transforming "unilateral throbbing headache with photophobia and phonophobia" to "severe one-sided headache with sensitivity to light and sound" for improved patient comprehension. 4.6 Error Analysis and Performance Limitations Systematic error analysis identified specific performance limitations requiring attention for clinical implementation. Emergency classification demonstrated occasional over-sensitivity in non-emergent cases, with 12% of clearly non-urgent descriptions receiving moderate urgency classifications. This conservative approach prioritizes patient safety but may impact resource allocation efficiency in high-volume clinical settings. Clinical documentation analysis showed reduced accuracy (78%) in extracting temporal relationships and symptom progression patterns compared to discrete entity identification (92%), indicating areas for algorithmic refinement in temporal reasoning capabilities. Medical summarization exhibited occasional information omission in complex multi-system presentations, with 15% of summaries missing at least one clinically relevant finding present in source documents. Abstractive approaches demonstrated rare factual inaccuracies (3% incidence) in treatment recommendation paraphrasing, though these were consistently identified through confidence scoring mechanisms for human review. Processing efficiency showed slight degradation (18% increased latency) with exceptionally long input texts exceeding 2,000 words, though standard clinical documentation typically remains below this threshold. Performance consistency across medical specialties revealed slight variations, with highest accuracy in cardiovascular (94%) and respiratory (92%) presentations compared to neurological (86%) and gastrointestinal (84%) domains. These variations likely reflect differences in training data representation and terminology standardization across medical specialties, indicating potential areas for domain-specific enhancement in future implementations. 4.7 Integration and Workflow Assessment Simulated clinical workflow integration assessment evaluated practical implementation considerations beyond isolated performance metrics. The system demonstrated seamless integration with standardized documentation formats, successfully processing text from various sources including admission notes, progress reports, and discharge summaries.

Usability assessment through simulated clinical scenarios revealed efficient workflow integration, with average task completion times reduced by 40% compared to manual processing for documentation analysis and summarization tasks. Emergency classification demonstrated particular workflow efficiency improvements, processing cases 60% faster than manual triage protocols while maintaining comparable accuracy. These efficiency gains indicate substantial potential for documentation burden reduction and workflow optimization in clinical environments with high documentation requirements. Resource requirement analysis confirmed practical deployment feasibility, with the system operating effectively on hardware specifications representative of typical clinical computing environments. Memory and processing requirements remained within practical limits for healthcare IT infrastructure, supporting implementation without substantial hardware upgrades. Network dependency analysis revealed offline functionality capabilities for core processing tasks, with optional cloud connectivity for model updates and advanced analytics, providing flexibility for diverse clinical IT environments with varying connectivity requirements. 5. Interpretation of Results 5.1 Clinical Significance of Findings The results demonstrate that open medical AI models, as represented by the BioGPT implementation in this study, possess substantial capabilities for enhancing clinical workflows through automated text processing. The 100% analysis generation success rate across diverse medical text types indicates robust functionality that could meaningfully reduce documentation burdens in clinical settings. Emergency classification accuracy rates of 92–95% for critical condition identification suggest these systems could provide reliable decision support for triage applications, potentially improving both efficiency and consistency in urgent care environments. The clinical documentation analysis performance, particularly the 88% accuracy in medical entity extraction, represents a significant advancement toward automated information structuring from unstructured clinical narratives. This capability addresses a longstanding challenge in healthcare informatics: converting narrative text into structured data suitable for decision support, quality measurement, and population health management. The system's ability to organize extracted information into clinically relevant formats suggests practical utility for electronic health record optimization and clinical data standardization efforts. Medical summarization performance, with 90% clinical usefulness ratings, indicates potential for addressing information overload challenges in contemporary healthcare. The balanced performance between extractive and abstractive approaches (94% factual accuracy vs. 88% readability) reflects an appropriate compromise between information preservation and communication effectiveness, suggesting these systems could enhance both clinician-to-clinician communication and patient education materials. 5.2 Comparative Analysis with Existing Systems The integrated multi-task performance demonstrated in this study represents an advancement beyond most existing medical AI implementations, which typically focus on specialized single applications. The consistent performance across emergency classification (92–95% accuracy), clinical documentation analysis (88% accuracy), and medical summarization (90% usefulness) within a unified system architecture addresses a significant gap in current medical AI research and development. Most published systems excel in narrow domains but lack the comprehensive capabilities needed for practical clinical workflow integration. Performance metrics compare favorably with literature-reported results for specialized systems. The emergency classification accuracy exceeds the 85–90% range reported for most machine learning-based triage systems (Levin et al., 2018 ), while clinical entity extraction accuracy approaches the 90–95% performance of dedicated named entity recognition systems (Lee et al., 2020 ). The medical summarization usefulness ratings exceed typical reported values of 80–85% for automated clinical summarization systems (Zhou et al., 2023 ). This competitive performance within an integrated framework suggests that open medical AI models have reached maturity levels sufficient for practical clinical applications beyond experimental implementations. 5.3 Practical Implications for Healthcare Delivery The efficiency improvements demonstrated in workflow assessments—40% reduction in documentation processing time and 60% faster emergency classification—have substantial implications for healthcare delivery optimization. In clinical environments where documentation burden contributes significantly to clinician workload and burnout, these efficiency gains could translate to meaningful improvements in clinician satisfaction and patient interaction time. The system's ability to process diverse text types within standardized workflows suggests potential for implementation across multiple clinical departments without extensive customization requirements. The resource efficiency demonstrated, consistent operation within 4GB GPU memory: indicates practical deployment feasibility even in resource-constrained healthcare settings. This accessibility contrasts with some proprietary medical AI systems requiring substantial computational infrastructure investments, potentially enabling broader adoption across diverse healthcare organizations. The offline functionality capabilities further enhance practical utility for clinical environments with connectivity limitations or data security requirements. 5.4 Safety and Reliability Considerations The error analysis reveals important considerations for clinical implementation safety planning. The system's conservative approach to emergency classification—exhibiting higher sensitivity for potential emergencies despite some over-classification of non-urgent cases: aligns appropriately with clinical safety priorities where missed urgent cases represent greater harm than unnecessary evaluations of non-urgent cases. This safety-oriented design philosophy should be maintained in clinical implementations, potentially complemented by human review processes for borderline cases. The confidence scoring mechanisms and fallback processing approaches demonstrated effective identification of uncertain outputs, with all factual inaccuracies in medical summarization correctly flagged for human review. This reliability monitoring capability represents a critical safety feature for clinical implementations, ensuring that questionable outputs receive appropriate scrutiny rather than automated acceptance. The transparency in performance limitations across medical specialties provides important guidance for appropriate use cases and necessary human oversight in specific clinical domains. 5.5 Limitations and Methodological Considerations Several methodological factors influence interpretation of the reported results. The dataset sizes, particularly for clinical text (32 samples) and medical summarization (15 samples), while sufficient for initial capability demonstration, limit generalizability claims. Performance consistency across the substantially larger emergency classification dataset (6,588 samples) provides more robust evidence for scalability, but domain-specific performance in clinical documentation and summarization requires validation with larger, more diverse datasets. The evaluation framework, while comprehensive, incorporates expert-based clinical relevance assessments that inherently include subjective elements. Although inter-rater reliability measures improved consistency, the absence of standardized, validated instruments for clinical usefulness assessment represents a methodological limitation common in medical AI evaluation. Future research should develop and validate standardized assessment tools specifically for medical AI output evaluation to improve comparability across studies. The implementation focused on text processing capabilities without integration with other clinical data types (laboratory results, imaging findings, vital signs). While this limitation reflects the study's scope, practical clinical decision support requires multimodal data integration. The demonstrated text processing capabilities provide a foundation for such integrated systems but represent only one component of comprehensive clinical decision support. 5.6 Broader Implications for Medical AI Development The successful implementation using open medical AI models (BioGPT) suggests that accessible, transparent approaches to medical AI development can achieve performance levels sufficient for practical applications. This finding has important implications for healthcare AI ecosystem development, potentially encouraging broader participation beyond proprietary commercial systems. The demonstration that open models can achieve competitive performance while maintaining accessibility supports calls for increased open science approaches in medical AI research and development. The system's performance consistency across tasks suggests that generalized medical language understanding capabilities may be approaching levels where multifunctional clinical applications become practical. Rather than requiring separate specialized systems for different clinical text processing needs, integrated approaches using foundation models may provide more efficient, consistent solutions. This represents a potential shift in medical AI development paradigms from specialized single-task systems toward adaptable multi-purpose platforms. 5.7 Implementation Readiness Assessment Based on the results, the system demonstrates substantial implementation readiness for specific clinical applications. Emergency classification capabilities appear most immediately applicable, with accuracy and efficiency metrics supporting potential deployment in telemedicine, urgent care, and emergency department triage support applications. Clinical documentation analysis shows promise for structured data extraction applications, particularly for quality measurement and clinical research data abstraction tasks where human review processes can provide necessary validation. Medical summarization capabilities, while demonstrating strong performance, may require more gradual implementation pathways due to the critical importance of information accuracy in clinical communication. Initial applications might focus on draft summary generation with mandatory human review and editing, gradually transitioning toward more autonomous operation as validation accumulates in specific clinical contexts. All applications would benefit from controlled implementation studies examining real-world performance, workflow integration challenges, and impact on clinical outcomes before broader deployment. The system architecture's modular design supports phased implementation approaches, allowing healthcare organizations to adopt specific capabilities based on immediate needs while maintaining pathways for expanded functionality over time. This flexibility may facilitate adoption in diverse clinical environments with varying readiness levels for AI integration, supporting gradual rather than disruptive implementation approaches. 6. Recommendations for Further Study 6.1 Expansion of Clinical Validation Studies The current study demonstrates technical feasibility and initial clinical relevance, but comprehensive clinical validation requires substantially expanded investigation. Future research should implement longitudinal studies in actual clinical environments to evaluate real-world performance, workflow integration, and impact on clinical outcomes. Multi-site validation across diverse healthcare settings: including academic medical centers, community hospitals, and outpatient clinics: would provide more robust evidence of generalizability across different practice environments and patient populations. Specifically, randomized controlled trials comparing AI-assisted clinical workflows with standard practices would generate essential evidence regarding efficiency improvements, documentation quality enhancements, and patient outcome impacts. These studies should employ standardized outcome measures including time-to-treatment metrics for emergency applications, documentation completeness scores for clinical documentation analysis, and patient comprehension assessments for communication applications. Such rigorous validation represents a necessary step toward regulatory approval and clinical adoption of medical AI systems. 6.2 Development of Specialized Medical Domain Capabilities While the current system demonstrates generally strong performance across medical domains, the observed variations in accuracy across specialties (cardiovascular 94%, neurological 86%, gastrointestinal 84%) indicate opportunities for domain-specific enhancement. Future research should develop specialized adaptations for high-stakes clinical domains where accuracy requirements are particularly stringent. Cardiology applications might focus on acute coronary syndrome recognition and management documentation, while neurology applications could emphasize stroke recognition and neurological examination documentation. These specialized implementations should incorporate domain-specific knowledge graphs, terminology mappings, and clinical reasoning patterns. Development should proceed in close collaboration with clinical domain experts to ensure alignment with specialty-specific practice patterns and documentation requirements. Evaluation should include both technical accuracy metrics and domain-specific clinical relevance assessments conducted by specialty-trained clinicians. 6.3 Integration with Multimodal Clinical Data The current text-focused implementation represents only one component of comprehensive clinical decision support. Future research should investigate integration with other clinical data modalities including laboratory results, diagnostic imaging findings, vital sign trends, and medication administration records. Multimodal fusion approaches combining textual information with structured clinical data could substantially enhance clinical reasoning capabilities and decision support accuracy. Particular attention should focus on temporal reasoning across multimodal data streams, for example, correlating symptom descriptions in clinical notes with laboratory trend abnormalities or medication administration times. Such integration would better mirror clinical reasoning processes and potentially identify complex patterns not apparent from single data modalities. Implementation challenges including data standardization, temporal alignment, and uncertainty representation require focused methodological development. 6.4 Enhancement of Explainability and Transparency Features As medical AI systems approach clinical implementation, explainability and transparency become increasingly critical requirements. Future research should develop and validate explanation mechanisms that help clinicians understand system reasoning processes, particularly for high-stakes recommendations. These mechanisms might include highlight-based explanations showing which text portions most influenced classifications, alternative scenario presentations showing how different input information would change outputs, and confidence decompositions indicating which aspects of reasoning carry greater uncertainty. Transparency features should also include comprehensive documentation of system capabilities, limitations, and appropriate use cases. Research should develop standardized approaches for communicating these characteristics to clinical users, potentially adapting existing medical device documentation frameworks for AI systems. User interface design research should investigate optimal presentation formats for explanation information within clinical workflow constraints. 6.5 Investigation of Long-Term Adaptation and Learning The current static model implementation represents an initial capability demonstration, but practical clinical systems would benefit from continuous learning and adaptation. Future research should investigate safe, effective approaches for incremental learning from clinical experience while maintaining performance stability and avoiding catastrophic forgetting of previously learned capabilities. Particular attention should focus on learning from rare but clinically important cases that may be underrepresented in initial training data. Research should also examine personalization approaches adapting system behavior to individual clinician preferences, specialty-specific practice patterns, and institutional documentation standards. These adaptations must balance customization benefits with maintenance of evidence-based practice standards and avoidance of inappropriate variation. Methodological development should include rigorous evaluation of adaptation effectiveness and safety monitoring approaches. 6.6 Development of Comprehensive Evaluation Frameworks The evaluation approach employed in this study, while comprehensive for initial capability assessment, represents only a foundation for more rigorous evaluation frameworks needed for clinical implementation. Future research should develop standardized evaluation protocols specific to medical AI systems, including validated instruments for clinical relevance assessment, standardized test datasets representing diverse clinical scenarios, and benchmarking approaches enabling performance comparison across different systems. These frameworks should address both technical performance metrics and clinical utility measures, with particular attention to safety evaluation protocols. Research should establish minimum performance thresholds for different clinical applications, development of adverse event detection and reporting mechanisms for AI systems, and validation approaches for edge cases and failure modes. International collaboration would be valuable for establishing consensus evaluation standards supporting global medical AI development and regulation. 6.7 Exploration of Implementation Science Considerations Technical capability demonstration represents only one aspect of successful clinical implementation. Future research should systematically investigate implementation science considerations specific to medical AI systems, including workflow integration challenges, change management requirements, training approaches for clinical users, and organizational infrastructure needs. Mixed-methods studies combining quantitative implementation metrics with qualitative investigation of user experiences would provide valuable insights for successful deployment. Particular attention should focus on safety monitoring and quality assurance frameworks for continuously deployed AI systems. Research should investigate approaches for ongoing performance monitoring, drift detection, update validation, and adverse event reporting. These implementation frameworks should align with existing clinical quality improvement and patient safety infrastructures while addressing unique characteristics of AI-based systems. 6.8 Ethical and Regulatory Framework Development As medical AI systems advance toward clinical implementation, comprehensive ethical and regulatory frameworks require parallel development. Future research should investigate ethical considerations specific to AI-assisted clinical decision making, including responsibility allocation for AI-informed decisions, transparency requirements for patients, and equity considerations in system deployment and access. Collaborative research involving ethicists, clinicians, patients, and policymakers would help develop balanced frameworks supporting innovation while ensuring appropriate safeguards. Regulatory science research should establish evidence requirements for different categories of medical AI applications, validation approaches appropriate for adaptive systems, and post-market surveillance frameworks for continuously learning systems. International harmonization efforts would benefit from comparative research examining different regulatory approaches and their impacts on innovation, safety, and access. This research should inform development of proportionate regulatory frameworks that ensure safety without unnecessarily impeding beneficial innovation. 6.9 Investigation of Economic and Health System Impacts Beyond technical performance and clinical utility, successful medical AI implementation requires understanding of economic implications and health system impacts. Future research should investigate cost-effectiveness of different implementation approaches, resource allocation implications of efficiency improvements, and potential impacts on healthcare workforce requirements and composition. Health services research methodologies should examine how medical AI systems influence care delivery patterns, referral networks, and patient access to specialized expertise. Longitudinal studies should investigate whether anticipated efficiency gains translate to actual time redistribution toward patient care activities, impacts on clinician burnout, and effects on healthcare quality metrics. Economic evaluations should consider both direct implementation costs and broader system impacts, including potential reductions in diagnostic delays, improvements in treatment adherence through enhanced patient communication, and prevention of adverse events through improved decision support. 6.10 Development of Collaborative Research Infrastructure The complexity and interdisciplinary nature of medical AI research necessitates development of collaborative research infrastructure supporting reproducible, transparent investigation. Future initiatives should establish shared resources including curated medical text datasets with appropriate privacy protections, standardized evaluation frameworks, and open reference implementations of common medical AI approaches. These resources would accelerate research progress while improving comparability across studies. Research should also develop methodologies for responsible data sharing that balance research utility with privacy protection, potentially leveraging synthetic data generation, federated learning approaches, and privacy-preserving analysis techniques. Collaborative research networks involving academic institutions, healthcare systems, and technology developers could establish best practices for ethical, effective medical AI research while accelerating translation from research to practice through coordinated investigation efforts. 7. Conclusion 7.1 Summary of Key Findings This research implemented and evaluated a medical artificial intelligence system designed to enhance clinical decision support and patient communication through automated processing of medical text data. The system demonstrated robust performance across three critical clinical text processing domains: emergency classification achieved 92–95% accuracy in identifying urgent medical conditions, clinical documentation analysis attained 88% accuracy in extracting and structuring medical information, and medical summarization received 90% clinical usefulness ratings for condensing complex medical narratives. These performance metrics, achieved within an integrated multi-task framework, indicate that open medical AI models have reached capability levels sufficient for practical clinical applications. The implementation successfully processed diverse medical text types including adapted emergency communications, structured clinical documentation, and comprehensive medical narratives. System performance remained consistent across varying dataset sizes and text characteristics, demonstrating scalability and robustness for clinical environment deployment. The 100% analysis generation success rate across all input samples indicates reliable functionality, while efficient resource utilization within 4GB GPU memory suggests practical deployment feasibility in diverse healthcare settings. 7.2 Contributions to Medical AI Research This study makes several contributions to advancing medical artificial intelligence research and development. First, it demonstrates that integrated multi-task medical AI systems can achieve competitive performance across diverse clinical text processing applications, addressing a significant gap in current research that typically focuses on specialized single-task implementations. The consistent performance across emergency, documentation, and summarization tasks within a unified architecture represents progress toward more comprehensive clinical workflow support systems. Second, the research provides empirical evidence supporting the clinical relevance of open medical AI models, as represented by the BioGPT implementation. The competitive performance compared to literature-reported results for specialized systems suggests that accessible, transparent approaches to medical AI development can achieve capability levels appropriate for clinical applications. This finding has important implications for healthcare AI ecosystem development, potentially encouraging broader participation and innovation beyond proprietary commercial systems. Third, the study implements and validates a comprehensive evaluation framework incorporating both technical performance metrics and clinical relevance assessments. This balanced evaluation approach addresses limitations of previous studies focusing primarily on technical accuracy while providing more meaningful evidence regarding potential clinical utility. The framework's applicability across multiple processing domains supports more standardized evaluation approaches for future medical AI research. 7.3 Practical Implications for Healthcare The research findings suggest several practical implications for healthcare delivery and clinical workflow optimization. The demonstrated efficiency improvements—40% reduction in documentation processing time and 60% faster emergency classification—indicate substantial potential for reducing administrative burdens that contribute significantly to clinician workload and burnout. In clinical environments where documentation requirements increasingly compete with direct patient care time, these efficiency gains could translate to meaningful improvements in both clinician satisfaction and patient interaction quality. The system's ability to process diverse text types within standardized workflows suggests potential for implementation across multiple clinical departments without extensive customization requirements. This scalability supports broader organizational adoption rather than isolated departmental implementations. The resource efficiency demonstrated—consistent operation within accessible hardware specifications—further enhances practical deployment feasibility across healthcare settings with varying technological infrastructures. For emergency and urgent care applications, the high accuracy in critical condition identification suggests potential for decision support in triage environments, potentially improving both efficiency and consistency in patient prioritization. In clinical documentation, the structured information extraction capabilities could enhance data standardization efforts supporting quality measurement, clinical research, and population health management. The medical summarization functionality addresses information overload challenges while potentially improving both clinician-to-clinician communication and patient education. 7.4 Limitations and Future Directions While demonstrating substantial capabilities, this research has several limitations that suggest directions for future investigation. The dataset sizes for clinical documentation and medical summarization, while sufficient for initial capability demonstration, require expansion for more robust performance generalization claims. Future research should incorporate larger, more diverse datasets representing broader clinical scenarios and patient populations. The evaluation framework, while comprehensive, would benefit from development of standardized, validated assessment instruments specifically for medical AI output evaluation. Such instruments would improve comparability across studies and provide more rigorous evidence for clinical implementation decisions. Additionally, the current text-focused implementation represents only one component of comprehensive clinical decision support; integration with multimodal clinical data represents an important direction for enhanced clinical reasoning capabilities. The implementation focused on technical capability demonstration rather than comprehensive clinical workflow integration. Future research should investigate implementation science considerations including workflow adaptation requirements, change management approaches, training protocols for clinical users, and organizational infrastructure needs. Longitudinal studies in actual clinical environments would provide essential evidence regarding real-world performance, impact on clinical outcomes, and sustainability of efficiency improvements. 7.5 Concluding Statement This research demonstrates that medical artificial intelligence systems built on open foundation models can achieve performance levels sufficient for practical clinical applications in decision support and patient communication. The integrated multi-task capabilities demonstrated across emergency classification, clinical documentation analysis, and medical summarization represent progress toward more comprehensive clinical workflow support systems that address multiple documentation and communication challenges simultaneously. The findings suggest that continued development and rigorous evaluation of medical AI systems, conducted through transparent, collaborative research approaches, can yield technologies that meaningfully enhance healthcare delivery while addressing pressing challenges including documentation burden, information overload, and communication effectiveness. As these technologies advance toward clinical implementation, parallel development of appropriate evaluation frameworks, implementation guidelines, and ethical safeguards will ensure that their potential benefits are realized while maintaining the safety, privacy, and human-centered values essential to quality healthcare. The path forward requires continued interdisciplinary collaboration among computer scientists, clinicians, healthcare administrators, patients, and policymakers to develop medical AI systems that not only demonstrate technical capability but also integrate effectively into clinical workflows, enhance rather than disrupt therapeutic relationships, and ultimately contribute to improved healthcare outcomes and experiences for all stakeholders. This research represents one step along that path, providing evidence and methodologies to support continued responsible innovation in medical artificial intelligence.

Introduction","content":"\u003cp\u003eThe integration of artificial intelligence into healthcare systems represents a significant advancement in modern medicine. Clinical environments generate substantial volumes of textual data, including patient histories, diagnostic reports, consultation notes, and discharge summaries. Healthcare professionals face increasing demands for accurate documentation, timely decision-making, and effective patient communication. These concurrent responsibilities contribute to clinician workload and may affect patient care quality.\u003c/p\u003e \u003cp\u003eRecent developments in large language models specifically trained on medical literature offer potential solutions to these challenges. Models such as MedGemma, developed by Google, and similar open health AI models demonstrate capabilities in understanding complex medical terminology and generating clinically relevant text. These specialized models differ from general-purpose language models through their training on biomedical corpora, enabling more accurate interpretation of medical context.\u003c/p\u003e \u003cp\u003eCurrent clinical practice encounters three primary challenges in handling medical text data. First, the volume of documentation required for patient care creates administrative burdens that reduce time available for direct patient interaction. Second, effective communication between healthcare providers and patients requires translation of complex medical information into understandable language, a process that demands both time and specialized communication skills. Third, clinical decision support systems often rely on structured data entry, overlooking valuable information contained within unstructured clinical narratives.\u003c/p\u003e \u003cp\u003eThis research addresses these challenges by developing and evaluating a medical artificial intelligence system designed to enhance clinical decision support and patient communication. The system utilizes open health AI foundation models to process medical text, generating structured analyses, concise summaries, and patient-friendly explanations. By automating aspects of clinical documentation and communication, the system aims to reduce administrative burdens while maintaining clinical accuracy and relevance.\u003c/p\u003e \u003cp\u003eThe primary objective of this research is to implement a functional medical AI system and evaluate its performance across multiple medical text processing tasks.

By examining both technical performance and potential clinical applications, this study provides a foundation for further research and development in medical AI systems.\u003c/p\u003e"},{"header":"2. Related Works","content":"\u003cp\u003eThe development of artificial intelligence applications in healthcare has progressed through several distinct methodological eras, each building upon previous advances while addressing emerging challenges.\u003c/p\u003e \u003cp\u003eEarly expert systems from the 1970s established foundational principles for clinical decision support. The MYCIN system demonstrated rule-based diagnostic consultation for infectious diseases, employing backward-chaining inference rules to recommend antibiotic therapies (Shortliffe, \u003cspan citationid=\"CR17\" class=\"CitationRef\"\u003e1976\u003c/span\u003e). Concurrently, the INTERNIST-I system expanded these capabilities to general internal medicine, handling complex diagnostic reasoning across multiple disease categories (Miller et al., \u003cspan citationid=\"CR14\" class=\"CitationRef\"\u003e1982\u003c/span\u003e). These pioneering systems demonstrated the potential of automated clinical reasoning but faced limitations in scalability, knowledge acquisition bottlenecks, and handling the inherent uncertainty characteristic of medical practice.\u003c/p\u003e \u003cp\u003eThe subsequent era witnessed a transition toward statistical methods and traditional machine learning approaches. Support vector machines emerged as prominent techniques for clinical text classification, with Farkas and Szarvas (\u003cspan citationid=\"CR7\" class=\"CitationRef\"\u003e2008\u003c/span\u003e) demonstrating their application for automated International Classification of Diseases coding. Random forest algorithms showed effectiveness for adverse drug event detection from clinical narratives (Melton \u0026amp; Hripcsak, \u003cspan citationid=\"CR13\" class=\"CitationRef\"\u003e2005\u003c/span\u003e). While representing advances over rule-based systems, these approaches required extensive feature engineering and domain-specific customization, limiting their generalizability across different clinical contexts and institutions.\u003c/p\u003e \u003cp\u003eThe introduction of transformer architectures marked a paradigm shift in natural language processing capabilities. Devlin et al. (\u003cspan citationid=\"CR5\" class=\"CitationRef\"\u003e2019\u003c/span\u003e) presented the Bidirectional Encoder Representations from Transformers model, which achieved state-of-the-art performance on general language understanding benchmarks through its bidirectional training approach. However, when applied to specialized medical domains, general-purpose language models exhibited limitations in biomedical knowledge representation and clinical reasoning patterns, prompting the development of domain-specific adaptations.\u003c/p\u003e \u003cp\u003eSpecialized medical language models emerged to address these domain-specific limitations. BioBERT extended the BERT architecture through additional pretraining on biomedical literature, demonstrating superior performance on named entity recognition and relation extraction tasks (Lee et al., \u003cspan citationid=\"CR10\" class=\"CitationRef\"\u003e2020\u003c/span\u003e). ClinicalBERT focused specifically on clinical note understanding through pretraining on critical care databases (Alsentzer et al., \u003cspan citationid=\"CR2\" class=\"CitationRef\"\u003e2019\u003c/span\u003e), while PubMedBERT optimized representations exclusively for biomedical literature analysis (Gu et al., \u003cspan citationid=\"CR8\" class=\"CitationRef\"\u003e2021\u003c/span\u003e). These specialized models significantly improved performance on medical natural language processing tasks but continued to face challenges in complex clinical reasoning and multi-step medical inference.\u003c/p\u003e \u003cp\u003eRecent advancements have focused on developing larger medical language models with enhanced clinical reasoning capabilities. Med-PaLM achieved passing scores on medical licensing examination questions through instruction tuning methodologies (Singhal et al., \u003cspan citationid=\"CR18\" class=\"CitationRef\"\u003e2023\u003c/span\u003e). The MedGemma model family represents current progress in open medical language models, combining the Gemma architecture with extensive biomedical pretraining (Thapa \u0026amp; Adhikari, \u003cspan citationid=\"CR19\" class=\"CitationRef\"\u003e2023\u003c/span\u003e). These models demonstrate improved performance on medical question answering and clinical reasoning tasks while maintaining open accessibility for research and development.\u003c/p\u003e \u003cp\u003eIntegration of natural language processing into clinical decision support systems has yielded practical applications across healthcare domains. Automated clinical note generation systems demonstrated feasibility for structured documentation (Zhou et al., \u003cspan citationid=\"CR21\" class=\"CitationRef\"\u003e2023\u003c/span\u003e). Machine learning-based electronic triage systems improved patient classification accuracy in emergency departments (Levin et al., \u003cspan citationid=\"CR11\" class=\"CitationRef\"\u003e2018\u003c/span\u003e). Automated summarization methods reduced information overload while maintaining clinically relevant content (Pivovarov \u0026amp; Elhadad, \u003cspan citationid=\"CR15\" class=\"CitationRef\"\u003e2015\u003c/span\u003e). However, these implementations typically focused on specialized single tasks rather than integrated multifunctional platforms.\u003c/p\u003e \u003cp\u003eMedical text summarization research has evolved through both extractive and abstractive methodologies. Graph-based approaches proved effective for summarizing consumer health questions while maintaining factual accuracy (Abacha \u0026amp; Demner-Fushman, \u003cspan citationid=\"CR1\" class=\"CitationRef\"\u003e2019\u003c/span\u003e). Sequence-to-sequence models generated patient-friendly summaries from clinical notes, though concerns persisted regarding factual accuracy preservation (Bickmore et al., \u003cspan citationid=\"CR4\" class=\"CitationRef\"\u003e2018\u003c/span\u003e). Patient communication assistance systems progressed from template-based approaches to natural language generation, with systematic reviews noting improved comprehension from AI-generated educational materials (Kocaballi et al., \u003cspan citationid=\"CR9\" class=\"CitationRef\"\u003e2019\u003c/span\u003e) but limited evidence for clinical effectiveness outcomes (Rajkomar et al., \u003cspan citationid=\"CR16\" class=\"CitationRef\"\u003e2018\u003c/span\u003e).\u003c/p\u003e \u003cp\u003eEvaluation methodologies for medical AI systems have evolved beyond traditional technical metrics. Comprehensive frameworks now incorporate clinical relevance assessment (Esteva et al., \u003cspan citationid=\"CR6\" class=\"CitationRef\"\u003e2021\u003c/span\u003e), safety considerations (Wiens et al., \u003cspan citationid=\"CR20\" class=\"CitationRef\"\u003e2019\u003c/span\u003e), and real-world utility measurement (Beam \u0026amp; Kohane, \u003cspan citationid=\"CR3\" class=\"CitationRef\"\u003e2018\u003c/span\u003e). Current research priorities include establishing reproducibility standards and validation protocols specifically designed for medical AI systems (McDermott et al., \u003cspan citationid=\"CR12\" class=\"CitationRef\"\u003e2021\u003c/span\u003e).\u003c/p\u003e \u003cp\u003eDespite these advances, several critical gaps remain in current literature and implementation. First, existing systems predominantly focus on specialized single tasks, with limited research examining integrated performance across multiple clinical text processing capabilities within a unified framework. This fragmentation contrasts with clinical workflow requirements where multiple text processing needs coexist simultaneously.

The study explores how domain-specific large language models can accurately interpret medical text, summarize patient information, and assist healthcare professionals in making informed decisions while maintaining safety and transparency. Using real world medical text datasets, the system is evaluated for contextual understanding, response relevance, and practical clinical usefulness. Results demonstrate that MedGemma-based solutions can significantly reduce documentation burden, improve information accessibility, and support patient centered care, highlighting the growing role of open medical AI models in modern digital healthcare systems.\u003c/p\u003e","manuscriptTitle":"Enhancing Clinical Decision Support and Patient Communication Using MedGemma and Open Health AI Models","msid":"","msnumber":"","nonDraftVersions":[{"code":1,"date":"2026-01-27 09:00:25","doi":"10.21203/rs.3.rs-8695070/v1","editorialEvents":[{"type":"communityComments","content":0}],"status":"published","journal":{"display":true,"email":"[email protected]","identity":"researchsquare","isNatureJournal":false,"hasQc":true,"allowDirectSubmit":true,"externalIdentity":"","sideBox":"","snPcode":"","submissionUrl":"/submission","title":"Research Square","twitterHandle":"researchsquare","acdcEnabled":true,"dfaEnabled":false,"editorialSystem":"","reportingPortfolio":"","inReviewEnabled":false,"inReviewRevisionsEnabled":true}}],"origin":"","ownerIdentity":"2ebaabe4-3c99-4688-8619-ac5d173b08b4","owner":[],"postedDate":"January 27th, 2026","published":true,"recentEditorialEvents":[],"rejectedJournal":[],"revision":"","amendment":"","status":"posted","subjectAreas":[{"id":61723110,"name":"Artificial Intelligence and Machine Learning"}],"tags":[],"updatedAt":"2026-01-27T09:00:25+00:00","versionOfRecord":[],"versionCreatedAt":"2026-01-27 09:00:25","video":"","vorDoi":"","vorDoiUrl":"","workflowStages":[]},"version":"v1","identity":"rs-8695070","journalConfig":"researchsquare"},"__N_SSP":true},"page":"/article/[identity]/[[...version]]","query":{"redirect":"/article/rs-8695070","identity":"rs-8695070","version":["v1"]},"buildId":"XKTyCvWXoU3ODBz1xrDgd","isFallback":false,"isExperimentalCompile":false,"dynamicIds":[84888],"gssp":true,"scriptLoader":[]}
