Purpose/Significance To establish a pre-structured electronic medical record (EMR) data management system, and to discuss its impact on the construction level of smart hospitals and the improvement of the hospitals’ medical, teaching, scientific research and management efficiency. Method/Process Based on the existing management model of EMR systems, a multi-level data management model for pre-structured EMR and the key technical path of “writing-storage-transfer-utilization” are designed. By unifying disease-specific templates, dictionary standards and construction paths, efficient management and utilization of EMR data can be achieved. Result/Conclusion The implementation of standardized medical record templates and data management systems effectively empower hospital medical care, teaching, research, and management, enhancing the standardization level of medical record writing and the utilization efficiency of data, and laying a high-quality medical record data foundation for the construction of smart hospitals.
