风险矩阵法在静脉用药调配中心肠外营养液配制中的价值

Objective To investigate the effectiveness of risk matrix method in optimizing parenteral nutrition solution preparation processes at pharmacy intravenous admixture service(PIVAS). Methods This study analyzed prescription data from January 2024 to June 2025 at our hospital's PIVAS. The control group used conventional process management from January to June 2024, while the observation group implemented risk matrix method optimization from July 2024 to June 2025. A total of 6,000 prescriptions and 50 risk points were sampled for each group. Comparative analysis was conducted on preparation nonconformity rate, risk event occurrence rate, risk level distribution, and preparation efficiency between the two groups. Results The observation group demonstrated significantly lower preparation nonconformity rates than the control group, reduced proportions of high-risk levels(E and H grades), decreased high-risk event occurrences, and improved preparation efficiency—all statistically significant(P<0.05). Conclusion The risk matrix method effectively optimizes parenteral nutrition solution preparation processes in PIVAS, reduces preparation risks, and enhances medication safety and operational efficiency.
