【Abstract】 Objective To enable deep integration and efficient utilization of cross-domain data, this study explores how to unlock the value of data elements to advance intelligent clinical applications in smart hospitals, thereby promoting high-quality hospital development by fostering "new-quality productive forces". Methods Leveraging hospital information infrastructure-including a centralized data platform and collaborative systems-we pursued a core construction pathway across four dimensions: unification of multi-campus data; integration of cross-institutional data within and beyond the hospital; linkage of medical data with home-based health data; and fusion of large-scale datasets with curated, high-quality knowledge bases. These efforts supported the development of clinical applications grounded in cross-domain data integration. Results The integrated approach yielded an efficient, intelligent clinical application system that enables unified patient data retrieval, intelligent diagnostic decision support, dynamic monitoring of chronic diseases, collaborative clinical research, and fine-grained workload management. Conclusion Building clinical applications on crossdomain data integrationnot only addresses the needs of clinical diagnosis and treatment, research services, and operational management, but also lays a solid foundation for smart hospital development.更多还原
