摘要
目的分析某三甲医院3年多重耐药菌感染趋势,了解多重耐药菌种类及分布特点,探索下一阶段多重耐药菌防控工作关键点。方法监测2014年1月至2016年12月住院患者致病菌中检出多重耐药菌3 921株,分析多重耐药菌检出率、感染部位、重点部门多重耐药菌构成比等相关数据。结果医院多重耐药菌的检出率3年来呈逐渐下降的趋势,分别为40.36%、36.92%、28.47%,差异有统计学意义(X^2=122.563,P=0.001);多重耐药菌感染部位分布连续3年以呼吸道感染占首位,分别59.14%、60.96%、45.75%,差异有统计学意义(X^2=66.972,P=0.001);ICU检出多重耐药菌在全院检出科室分布中的构成比逐年下降,分别为30.54%、28.60%、25.78%,差异有统计学意义(X^2=7.000,P=0.030)。结论近年来社区检出多重耐药菌有增多的趋势,而本院多重耐药菌检出逐年下降,至2016年全院各科室检出多重耐药菌构成比分布趋于均匀,符合各专科细菌感染的特点,消除了多重耐药菌集中在医院感染高危科室检出率高的现象。
Objective To analyze the multiple drug - resistant Organism （MDRO） infection trend in a 3 A Grade Hospital in 3 years, to explore the characteristic of nosocomial MDRO infection and the pivotal prevention and control of MDRO. Methods The data of inpatients from January 2014 to December 2016 were analyzed. A total of 3 921 strains of MDRO were detected. The detection rates of MDRO, locations of infection, and nosocomial infection rates of the key de- partments were analyzed. Results Significant annually decreasing tendency was found on positive rate of MDRO, from 40. 66% to 28.47% （ X^2 = 122. 563, P = 0. 001 ）. The positive rate of respiratory infections of nosocomial MDRO was the first in 3 years, and decreasing significantly from 60.96% to 45.75% （ X^2 =66. 972, P =0. 001 ）. Constituent ratios of MDRO infection in ICU was significantly reduced from 30. 54% to 25.78% （ X^2 = 7. 000, P = 0. 030）. Conclusion Ac- cording to the three years monitoring data, the current prevention and control measures are effective in general and should be maintained. Moreover, new measures should be explored.
