目的: 本研究旨在评估广东省药品挂网价格相对于联盟集采中选价的偏离程度,为药品价格监管与医院采购工作提供参考。方法: 构建价格偏离度指标,利用IBM SPSS Statistics 27软件,采用曼-惠特尼U检验和皮尔逊相关性分析方法实证研究。结果: 58.89%的药品价格偏离度未超过0.5。不同剂型间的偏离度存在显著差异,如栓剂显著高于注射剂,且挂网时间与偏离度呈弱相关。但原料药资质、企业产权性质、上市状态、是否纳入医保目录等因素均未产生统计学上的显著影响。结论: 建议将价格偏离度指标纳入常态化价格监测,实施基于剂型等关键因素的精细化治理,并落实药品购销双方的价格管控责任。

Objective: This study aims to evaluate the degree of deviation of Guangdong Province's drug online listing prices from the winning bid prices in the alliance centralized procurement, providing a reference for drug price regulation and hospital procurement. Methods: A price deviation index was constructed, and empirical research was conducted using IBM SPSS Statistics 27 software, employing the Mann-Whitney U test and Pearson correlation analysis methods. Results: 58.89% of the drug prices had a deviation degree not exceeding 0.5. Significant differences in deviation degrees were observed among different dosage forms, with suppositories showing a significantly higher deviation than injections, and a weak correlation between online listing duration and deviation degree. However, factors such as the qualification of active pharmaceutical ingredients, the nature of enterprise property rights, the status of market listing, and whether the drug was included in the medical insurance directory did not have a statistically significant impact. Conclusion: It is recommended to incorporate the price deviation index into regular price monitoring, implement refined governance based on key factors such as dosage form, and enforce price control responsibilities for both drug buyers and sellers.
