对应分析在探讨多重耐药菌季节分布中的应用

Exploring the seasonal distribution of Multi-drug resistant organism based on correspondence analysis

目的采用对应分析探讨医院多重耐药菌在时间上的流行分布特征,为有针对性地制定医院感染防控策略提供依据。方法采用简单对应分析与多重对应分析相结合的方法对云南省某医院2016年多重耐药菌目标监测数据进行分析。结果对应分析结果显示某些多重耐药菌具有明显的季节相关性,如耐甲氧西林金黄色葡萄球菌检出与12月份有联系,耐碳青霉烯类铜绿假单胞菌检出与5月份联系紧密。结论医院多重耐药菌种在不同月份呈现不同分布特征,掌握其分布规律有利于提高医院感染风险预警主动性。对应分析方法适宜于疾病群体现象与季节性关系的探讨,并可获得良好效果,为医院决策者提供有力的信息指导。

Objective To explore the time distribution of multi-drug resistant organisms（ MDRO） in hospital and to provide the basis for targeted prevention and control strategy. Methods Single and multi correspondence analysis（ CA） were used to analyze the surveillance data of MDRO in a hospital of Yunnan in 2016. Results The results showed that the distribution of MDRO had obvious seasonal relativity. For example,the MRSA had a close relationship with December and CRPA were closely linked with May. Conclusion MDRO have different distribution characteristic in different month. Grasping its features was conducive to improve the initiative of risk warning of hospital infection. CA is suitable for exploring the relationship between disease population phenomenon and seasonality,and can get good results,which provides powerful information guidance for hospital decision makers.
