ABSTRACT: Objective: To explore the main causes of blood discard during blood component preparation, formulate targeted solution strategies, and provide a basis for improving the quality of blood preparation and conserving blood resources. Methods: Data from 127 discarded products during the 12-month pre-intervention period (June 2024 to June 2025) were collected as a baseline to analyze discard causes and distribution. Subsequently, twelve staff members were randomly divided into a control group (6 individuals, continuing conventional work mode) and a study group (6 individuals, implementing targeted solution strategies for 3 months). Post-intervention quality management scores were compared between groups, and discard rates during the intervention period were collected for supplementary comparison. Results: Among 127 discarded products, the proportions for ordinary frozen plasma (53.54%), virus-inactivated plasma (22.05%), and whole blood (20.47%) were relatively high. The primary cause of discard was lipemic blood (70.87%), followed by testing non-conformance (10.24%), insufficient volume and clots (5.51% each), etc. After the 3-month intervention, the blood discard rate in the study group was 18.6% lower than that in the control group. The study group’s quality management scores across seven dimensions—blood control, collection management, etc.—were significantly higher than those of the control group, with a statistically significant difference (P
