Abstract: Objective To establish a multidimensional management system of medical consumables（MMM-MCM） based on hospital resource planning （HRP） system and validate its operational efficacy. MethodA four-dimensional management framework was constructed encompassing quality control [unique device identifier（UDI） traceability], cost optimization （ABC-VEN classification）, operational efficiency （dynamic inventory）, and risk mitigation （integrity early-warning）.A prospective intervention research method was used to analyze the hospital consumables data （1 236 589 items） from 2020 to 2024, and a difference-in-difference （DID） model was used to analyze the management efficiency before and after the implementation of MMM-MCM. Results Post-implementation outcomes demonstrated 35.1% improvement in comprehensive management score （92.3±3.1） compared with baseline （P<0.001）. Specifically, （1） the inventory turnover increased by 38.7% with acceptance error rate reduced to 0.9%; （2） the supplier license completeness reached 99.6% with 28.5% higher delivery punctuality;（3）high-value consumables cost accounting errors decreased to 2.1%, freeing up ¥21 million capital. Conclusion The MMM-MCM model significantly enhances standardization in medical consumables management after innovatively integrating the HRP system with the whole-life management of medical consumables, providing a replicable paradigm for hospital lean operations.
