摘　　要：目的针对目前医院手术器械管理主观性较强、分类管理方法忽略市场供应风险的问题,提出一种科学的手术器械分类方法,为提高手术器械物流管理水平提供管理依据。方法收集2021年H医院151件手术器械的出库数据,基于Kraljic矩阵构建手术器械分类指标体系,使用主成分分析法(Principal Component Analysis,PCA)对指标体系降维,将多维空间上复杂的手术器械分布展现在低维空间中,根据对主成分的解读及手术器械分布情况,基于Kraljic理论对手术器械分类。结果结合Kraljic矩阵和领域经验构建出含10个特征的指标体系,使用PCA算法提取出2个主成分,分析得出主成分1由经济价值主导,主成分2由市场供应风险主导,最后基于Kraljic矩阵将手术器械分为战略类22件,杠杆类15件,瓶颈类46件,常规类68件,并提出手术器械分类管理方法。结论基于Kraljic矩阵和PCA算法的手术器械分类管理研究为手术器械物流管理提供了科学实用的管理办法。Objective To propose a scientific classification method for surgical instruments,addressing the subjectivity and neglect of market supply risk in the current hospital surgical instrument management,which will provide a basis for improving the level of surgical instrument logistics management.Methods The outbound data of 151 surgical instruments from H Hospital in 2021 was collected.An indicator system for surgical instrument classification was constructed using the Kraljic matrix.Principal component analysis(PCA)was employed to reduce the dimensionality of the indicator system,presenting the complex distribution of surgical instruments in a lower-dimensional space.Based on the interpretation of principal components and the distribution of surgical instruments,we classified them using the Kraljic matrix theory.Results Combining the Kraljic matrix with domain expertise,we developed a 10-feature indicator system and extracted 2 principal components using PCA.Principal Component 1 was dominated by economic value,while Principal Component 2 was influenced by market supply risk.Using the Kraljic matrix,we categorized surgical instruments into strategic(22 items),leverage(15 items),bottleneck(46 items),and routine(68 items)classes.We proposed a classification management method for surgical instruments.Conclusion This research on surgical instrument classification management,based on the Kraljic matrix and PCA,provides a practical and scientific approach for surgical instrument logistics management.
