Abstract: Objective To develop and a hierarchical training system based on the Miller pyramid model ifor enhancing the job competency of blood collection and supply technicians in blood stations. Methods A preliminary indicator framework was established through literature analysis and semi-structured interviews. Core indicators were identified using the Delphi method (2 rounds) with weights determined via the he analytic hierarchy process. A dynamic evaluation mechanism was introduced to optimize the training pathways. Results A hierarchical training system was finalized, comprising 4 first-level indicators, 13 second-level indicators and 53 three-level indicators. The pilot study showed that the experimental group was significantly better than the control group in theoretical assessment performance (92.3±3.1 vs. 85.6±4.2), operation compliance rate (100% vs. 83.3%) and blood donor satisfaction score (4.8±0.2 vs. 4.2±0.3) (P<0.05). Conclusion The Miller pyramid-based hierarchical training system, featuring a "theory-application-practice" ladder and dynamic assessment, can effectively improve the comprehensive competency of blood collection and supply technicians and provide a scientific basis for standardized training in blood centers.
