Application of Supply Processing and Distribution Model in Interventional Consumables Management Based on Whole-Process Coding Technology

Objective: To explore the application effectiveness of the integration of the whole-process coding technology and Supply Processing and Distribution (SPD) supply chain management model in the management of interventional consumables. Methods: Based on the original SPD management mode of interventional consumables in a tertiary hospital, a standardized classification and coding system was constructed, and a basic database of consumables with a unique identification code was established and integrated into various information management platforms to achieve the whole - process code management. Comparison and analysis were made on the changes in key indicators such as the timely supply rate of interventional consumables, the traceability accuracy of barcodes, the matching accuracy between consumables and pricing items, the information registration accuracy, and the billing - outbound matching rate before and after the application of the system. Results: After the implementation of the integrated management model, all measured indicators demonstrated statistically significant improvements ( p < 0.05). The timeliness of consumable supply increased from 81.53% to 95.69%, traceable barcode accuracy from 85.28% to 96.39%, correct match rate between consumables and pricing items from 92.08% to 99.17%, accuracy of consumable information registration from 94.17% to 99.31%, and consistency rate between consumable pricing and inventory outflow from 96.39% to 99.58%. Staff satisfaction also significantly rose from 64.33% to 93.33% (all p < 0.05). Conclusion: This integrated management model significantly improves the lean and intelligent management of interventional consumables and demonstrates strong potential for clinical application and broader adoption.
