TY - JOUR T1 - Multi-Relational Graph Learning for Patient Similarity and Clinical Decision Support AU - Claire Martin AU - Ahmed Mansour JF - Journal of Artificial Intelligence for Healthcare Systems JO - J. Artif. Intell. Healthc. Syst. SN - 3149-8981 Y1 - 2024 VL - 3 IS - 1 SP - 20 N2 - The integration of graph-based architectures into healthcare systems represents a pivotal advancement, enabling personalized clinical intelligence through patient similarity metrics. This conceptual manuscript proposes a novel framework, the Graph-Integrated Patient Affinity Network (GIPAN), that orients patient data as interconnected nodes within a dynamic graph, facilitating similarity-driven insights for clinical decision-making. Drawing from theoretical foundations in clinical AI infrastructures, electronic health record (EHR) ecosystems, and interoperability frameworks, GIPAN emphasizes layered graph embeddings that capture multidimensional patient profiles, including temporal trajectories, comorbidity patterns, and treatment responses. The architecture incorporates feedback loops for adaptive similarity refinement, ensuring alignment with evolving clinical workflows without empirical validation. Key theoretical contributions include formulas for similarity propagation across graph layers and governance load estimation in deployment scenarios. By synthesizing recent literature on graph neural networks in healthcare analytics and decision-support pipelines, this work highlights the infrastructural prerequisites for scalable, privacy-preserving patient matching. Potential impacts encompass enhanced diagnostic precision in heterogeneous populations and streamlined resource allocation in personalized medicine ecosystems. This conceptual design underscores the need for robust AI governance to mitigate biases in similarity computations, paving the way for future theoretical explorations in graph-centric clinical intelligence.
